I am trying to create image 15-puzzle game, where you have to combine the image by sliding the squares.
Almost everything works correctly, except that instead of showing the image inside a button it shows it as a text "System.Drawing.Image".
Here is my MainWindow.xaml.cs code:

What am I doing wrong??
Here is what I did to get this to work.
I created a list of StackPanels similar to your button list.
private static readonly List<StackPanel> StackPanels = new List<StackPanel>(15);
then populated the list like you did the buttons..
private static readonly List<StackPanel> StackPanels = new List<StackPanel>(15);
Then Here is the for loop with the fix in the CreateDynamicWPFGrid method. Added the Stack panel to the content and added the Image to the stack panel after converting it to a Control.Image.
// Bind Buttons and Grid Cells
int j = 0;
var imgList = Randomizer();
for (var i = 0; i < 16; i++)
{
if (i % 4 != _xPos || _yPos != i / 4)
{
//Add image in a button
var bitmapImage = new BitmapImage();
var bitmap = imgList[j];
using (var memoryStream = new MemoryStream())
{
bitmap.Save(memoryStream, System.Drawing.Imaging.ImageFormat.Bmp);
bitmapImage.BeginInit();
bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
bitmapImage.StreamSource = memoryStream;
bitmapImage.EndInit();
}
var image = new System.Windows.Controls.Image
{
Source = bitmapImage,
Stretch = Stretch.None
};
var currentstack = StackPanels[j];
currentstack.Orientation = Orientation.Horizontal;
currentstack.Children.Add(image);
Buttons[j].Content = currentstack;
Buttons[j].Click += Button_Click;
Grid.SetColumn(Buttons[j], i % 4);
Grid.SetRow(Buttons[j], i / 4);
dynamicGrid.Children.Add(Buttons[j]);
j++;
}
}

In this Application, i have a car class with a method called Spawn (which should draw the object on a Canvas which i defined in the XAML file). I call the Method in MainWindow, but when I run my program, there is no car being drawn onto the Canvas.
Here is the Spawn method:
public void Spawn(Canvas cvs)
{
cvs = new Canvas();
cvs.Children.Clear();
carBody.Width = 70;
carBody.Height = 120;
carBody.Background = new SolidColorBrush(Color);
Canvas.SetLeft(carBody, SpawnLocation.X);
Canvas.SetTop(carBody, SpawnLocation.Y);
Rectangle[] tires = new Rectangle[4];
Rectangle[] windows = new Rectangle[2];
Label lblBrand = new Label();
RotateTransform rotation = new RotateTransform();
// Reifen
tires[0] = new Rectangle()
{
Fill = Brushes.Black,
Width = 20,
Height = 30
};
Canvas.SetLeft(tires[0], -9);
Canvas.SetTop(tires[0], 18);
tires[1] = new Rectangle()
{
Fill = Brushes.Black,
Width = 20,
Height = 30
};
Canvas.SetLeft(tires[1], 61);
Canvas.SetTop(tires[1], 18);
tires[2] = new Rectangle()
{
Fill = Brushes.Black,
Width = 20,
Height = 30
};
Canvas.SetLeft(tires[2], -9);
Canvas.SetTop(tires[2], 80);
tires[3] = new Rectangle()
{
Fill = Brushes.Black,
Width = 20,
Height = 30
};
Canvas.SetLeft(tires[3], 61);
Canvas.SetTop(tires[3], 80);
// Fenster
windows[0] = new Rectangle() // Front
{
Fill = Brushes.White,
Width = 50,
Height = 40
};
Canvas.SetLeft(windows[0], 0);
Canvas.SetTop(windows[0], 0);
windows[1] = new Rectangle() // rear
{
Fill = Brushes.White,
Width = 50,
Height = 50
};
Canvas.SetLeft(windows[1], 0);
Canvas.SetTop(windows[1], 0);
// Label Automarke
lblBrand.Width = 40;
lblBrand.Height = 23;
lblBrand.Content = Brand;
// Add2Canvas
for (int i = 0; i < tires.Length; i++)
carBody.Children.Add(tires[i]);
for (int i = 0; i < windows.Length; i++)
carBody.Children.Add(windows[i]);
carBody.Children.Add(lblBrand);
if (Direction == "nord")
{
rotation.Angle = 0;
rotation.CenterX = SpawnLocation.X;
rotation.CenterY = SpawnLocation.Y;
carBody.RenderTransform = rotation;
}
else if (Direction == "süd")
{
rotation.Angle = 180;
rotation.CenterX = SpawnLocation.X;
rotation.CenterY = SpawnLocation.Y;
carBody.RenderTransform = rotation;
}
else if (Direction == "west")
{
rotation.Angle = 90;
rotation.CenterX = SpawnLocation.X;
rotation.CenterY = SpawnLocation.Y;
carBody.RenderTransform = rotation;
}
else if (Direction == "ost")
{
rotation.Angle = 270;
rotation.CenterX = SpawnLocation.X;
rotation.CenterY = SpawnLocation.Y;
carBody.RenderTransform = rotation;
}
cvs.Children.Add(carBody);
}
Calling the methodMainWindow:
Car car1;
public MainWindow()
{
InitializeComponent();
car1 = new Car("Audi", Colors.Red);
car1.Direction = "west";
car1.SpawnLocation = new Point(550, 340);
car1.Spawn(gameScreen);
}
Thanks in advance!
Fixed it! I initialized the argmument of my Spawn method, it now works after I deleted it.
My method looked like this first:
public void Spawn(Canvas cvs)
{
cvs = new Canvas();
cvs.Children.Clear();
carBody.Width = 70;
I initialized my the Argument, but since i don't wanna create a new Canvas, i deleted these two first lines of my method.
public void Spawn(Canvas cvs)
{
carBody.Width = 70;
carBody.Height = 120;
carBody.Background = new SolidColorBrush(Color);
Now its working fine.
I have C# project already done but im having issue with printing it's charts when comes out with more pages of data points, i got the scroll bar work when start getting more pages so the user can review all data on all pages but i could not find how to make the print preview shows them or print them,
when click on print, it shows only the first page on the print preview and same thing when print it out.
her is the print code:
PrintPreviewDialog ppd = new PrintPreviewDialog();
ppd.Document = this.chart1.Printing.PrintDocument;
((Form)ppd).WindowState = FormWindowState.Maximized;
chart1.Printing.PrintDocument.DefaultPageSettings.Landscape = true;
chart1.Printing.PrintDocument.DefaultPageSettings.Margins.Left = 0;
chart1.Printing.PrintDocument.DefaultPageSettings.Margins.Right = 0;
chart1.Printing.PrintDocument.DefaultPageSettings.Margins.Top = 0;
chart1.Printing.PrintDocument.DefaultPageSettings.Margins.Bottom = 0;
ppd.ShowDialog();
and here is the chart load code:
public void loadChart(string sqlvalue)//load chart method
{
chart1.ChartAreas[0].AxisY.Maximum = 55;
chart1.ChartAreas[0].AxisY.Minimum = 35;
chart1.ChartAreas[0].AxisY.Interval = 5;//control how many lines/Interval
chart1.ChartAreas[0].AxisY.ScrollBar.Enabled = true;
chart1.ChartAreas[0].AxisY.ScaleView.Zoomable = true;
chart1.ChartAreas[0].AxisX.Minimum = 0;
// chart1.ChartAreas[0].AxisX.Maximum = 10;
chart1.ChartAreas[0].AxisX.Interval = 1;
//X AXES label angle
chart1.ChartAreas[0].AxisX.LabelStyle.Angle = 60;
da = new SqlDataAdapter(sqlvalue, cn.connect());
da.Fill(dt);
this.chart1.DataSource = dt;
this.chart1.Series["left"].XValueMember = dt.Columns[3].ToString();//date data
this.chart1.Series["left"].YValueMembers = dt.Columns[1].ToString();//spindle 1 data
this.chart1.Series["Right"].YValueMembers = dt.Columns[2].ToString();//spindle 2 data
//label the series lines, Backcolor and forcolor
chart1.Series[0].LabelBackColor = Color.Red;
chart1.Series[0].LabelForeColor = Color.White;
//datapoint marker's color, bordercolor,style and size
chart1.Series[0].MarkerColor = Color.White;
chart1.Series[0].MarkerBorderColor = Color.Black;
chart1.Series[0].MarkerStyle = MarkerStyle.Circle;
chart1.Series[0].MarkerSize = 8;
//datapoint marker's color, style and size
chart1.Series[1].MarkerColor = Color.White;
chart1.Series[1].MarkerBorderColor = Color.Black;
chart1.Series[1].MarkerStyle = MarkerStyle.Circle;
chart1.Series[1].MarkerSize = 8;
chart1.Series[1].LabelBackColor = Color.Blue;
chart1.Series[1].LabelForeColor = Color.White;
//Chart background lines color
chart1.ChartAreas[0].AxisX.MajorGrid.LineColor = Color.Silver;
chart1.ChartAreas[0].AxisY.MajorGrid.LineColor = Color.Silver;
this.chart1.DataBind();
cn.disconnect();
// enable autoscroll
chart1.ChartAreas[0].CursorX.AutoScroll = true;//------------
chart1.ChartAreas[0].AxisX.ScaleView.Zoomable = true;
chart1.ChartAreas[0].AxisX.ScaleView.Zoom(0, 15);
chart1.ChartAreas[0].AxisX.ScrollBar.ButtonStyle = ScrollBarButtonStyles.SmallScroll;
// set scrollbar small change to the target size
chart1.ChartAreas[0].AxisX.ScaleView.SmallScrollSize = 15;
Legend left = new Legend();
Legend LC = CustomCloneLegend(chart1, left);
chart1.Legends.Add(LC);
chart1.Padding = Padding.Empty;
ChartArea CA = chart1.ChartAreas[0];
CA.Position = new ElementPosition(4,6, 100, 90);
}
Thank you for your time and help, here is the chart code update:
private static Image MergeImages(List<Image> imageList)
{
var finalSize = new Size();
foreach (var image in imageList)
{
if (image.Width > finalSize.Width)
{
finalSize.Width = image.Width;
}
finalSize.Height += image.Height;
}
var outputImage = new Bitmap(finalSize.Width, finalSize.Height);
using (var gfx = Graphics.FromImage(outputImage))
{
var y = 0;
foreach (var image in imageList)
{
gfx.DrawImage(image, 0, y);
y += image.Height;
}
}
return outputImage;
}
The second method:
List<Image> ChartsToImages(List<Chart> charts)
{
var imageList = new List<Image>();
foreach (var c in charts)
{
using (var ms = new MemoryStream())
{
c.SaveImage(ms, ChartImageFormat.Png);
var bmp = System.Drawing.Bitmap.FromStream(ms);
imageList.Add(bmp);
}
}
return imageList;
}
and this code
var chartList = new List<Chart> { chart1 };
var imageList = ChartsToImages(chartList);
var finalImage = MergeImages(imageList);
finalImage.Save("D:\\Junk.png", ImageFormat.Png);
Im not sure is that what you mean by your first comment, but i found this code here under Converting chart to image questions. this code convert and saves the chart in the same amount of pages but i need to show them in the printpreviewcontrol and print them.
Below code refers to the as per page count starting point and ending point based printing. And Grid view value chars are row loop based counting the page.
private int numberOfItemsPerPage = 0;
private int numberOfItemsPrintedSoFar = 0;
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
int height = 480; //page height stating point
for (int l = numberOfItemsPrintedSoFar; l < dataGridView2.Rows.Count; l++)
{
numberOfItemsPerPage = numberOfItemsPerPage + 1;
if (numberOfItemsPerPage <= 25) // 25 is Page Line Item
{
numberOfItemsPrintedSoFar++;
if (numberOfItemsPrintedSoFar <= dataGridView2.Rows.Count)
{
height += dataGridView2.Rows[0].Height;
e.Graphics.DrawString(dataGridView2.Rows[l].Cells[0].FormattedValue.ToString(), dataGridView2.Font = new Font("Book Antiqua", 8), Brushes.Black, new RectangleF(5, height, dataGridView2.Columns[0].Width, dataGridView2.Rows[0].Height));
e.Graphics.DrawString(dataGridView2.Rows[l].Cells[1].FormattedValue.ToString(), dataGridView2.Font = new Font("Book Antiqua", 8), Brushes.Black, new RectangleF(170, height, dataGridView2.Columns[0].Width, dataGridView2.Rows[0].Height));
e.Graphics.DrawString(dataGridView2.Rows[l].Cells[2].FormattedValue.ToString(), dataGridView2.Font = new Font("Book Antiqua", 8), Brushes.Black, new RectangleF(290, height, dataGridView2.Columns[0].Width, dataGridView2.Rows[0].Height));
e.Graphics.DrawString(dataGridView2.Rows[l].Cells[3].FormattedValue.ToString(), dataGridView2.Font = new Font("Book Antiqua", 8), Brushes.Black, new RectangleF(345, height, dataGridView2.Columns[0].Width, dataGridView2.Rows[0].Height));
}
else
{
e.HasMorePages = false;
}
}
else
{
numberOfItemsPerPage = 0;
e.HasMorePages = true;
return;
}
}
numberOfItemsPerPage = 0;
numberOfItemsPrintedSoFar = 0;
}
I am working on WPF application. I have data in the DataGrid which I have to print all the data present in it. I tried like this...
publicMainWindow()
{
InitializeComponent();
DataTabledt = newDataTable();
dt.Columns.Add("S.No");
dt.Columns.Add("Name");
dt.Columns.Add("Father's Name");
dt.Columns.Add("D-O-B");
dt.Columns.Add("Qualification");
dt.Columns.Add("Gender");
dt.Columns.Add("SSC %");
dt.Columns.Add("+2 %");
dt.Columns.Add("Graduation %");
dt.Columns.Add("Work Experience");
dt.Columns.Add("Company");
object[] rowValues = {"01","Gopi","Ravi","31","Degree","M", "88","85", "80","2 Years","Blah Blah"};
dt.Rows.Add(rowValues);
dt.AcceptChanges();
myGrid.DataContext = dt.DefaultView;
}
privatevoidPrint_Click(object sender, RoutedEventArgs e)
{
PrintDialogprintDlg = newPrintDialog();
if ((bool)printDlg.ShowDialog().GetValueOrDefault())
{
Sizepagesize = newSize(printDlg.PrintableAreaWidth,printDlg.PrintableAreaHeight);
myGrid.Measure(pagesize);
myGrid.Arrange(newRect(5, 5, pagesize.Width, pagesize.Height));
printDlg.PrintVisual(myGrid, "Personal Information");
}
}
when I click on print button it is printing only the data which we can see as below
But in my case it is not printing work experience and company columns. How can I Print all the fields. Please help me out
EDIT: I think FlowDocument is used, but suppose I have 50 rows I cannot use FlowDocument. How can I Print in this case.
I have done code recently. It is tested code.It will print every datagrid with all records.It is easy and simple code.You would add a class. If you want to decorate a datagrid then go to PrintDG class then decorate it according to your own requirement.
Follow these steps.
Step1: Add these references on top.
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Media;
public class PrintDG
{
public void printDG(DataGrid dataGrid, string title)
{
PrintDialog printDialog = new PrintDialog();
if (printDialog.ShowDialog() == true)
{
FlowDocument fd = new FlowDocument();
Paragraph p = new Paragraph(new Run(title));
p.FontStyle = dataGrid.FontStyle;
p.FontFamily = dataGrid.FontFamily;
p.FontSize = 18;
fd.Blocks.Add(p);
Table table = new Table();
TableRowGroup tableRowGroup = new TableRowGroup();
TableRow r = new TableRow();
fd.PageWidth = printDialog.PrintableAreaWidth;
fd.PageHeight = printDialog.PrintableAreaHeight;
fd.BringIntoView();
fd.TextAlignment = TextAlignment.Center;
fd.ColumnWidth = 500;
table.CellSpacing = 0;
var headerList = dataGrid.Columns.Select(e => e.Header.ToString()).ToList();
List<dynamic> bindList = new List<dynamic>();
for (int j = 0; j < headerList.Count; j++)
{
r.Cells.Add(new TableCell(new Paragraph(new Run(headerList[j]))));
r.Cells[j].ColumnSpan = 4;
r.Cells[j].Padding = new Thickness(4);
r.Cells[j].BorderBrush = Brushes.Black;
r.Cells[j].FontWeight = FontWeights.Bold;
r.Cells[j].Background = Brushes.DarkGray;
r.Cells[j].Foreground = Brushes.White;
r.Cells[j].BorderThickness = new Thickness(1, 1, 1, 1);
var binding = (dataGrid.Columns[j] as DataGridBoundColumn).Binding as Binding;
bindList.Add(binding.Path.Path);
}
tableRowGroup.Rows.Add(r);
table.RowGroups.Add(tableRowGroup);
for (int i = 0; i < dataGrid.Items.Count; i++)
{
dynamic row;
if (dataGrid.ItemsSource.ToString().ToLower() == "system.data.linqdataview")
{ row = (DataRowView)dataGrid.Items.GetItemAt(i); }
else
{
row = (BalanceClient)dataGrid.Items.GetItemAt(i);
}
table.BorderBrush = Brushes.Gray;
table.BorderThickness = new Thickness(1, 1, 0, 0);
table.FontStyle = dataGrid.FontStyle;
table.FontFamily = dataGrid.FontFamily;
table.FontSize = 13;
tableRowGroup = new TableRowGroup();
r = new TableRow();
for (int j = 0; j < row.Row.ItemArray.Count(); j++)
{
if (dataGrid.ItemsSource.ToString().ToLower() == "system.data.linqdataview")
{
r.Cells.Add(new TableCell(new Paragraph(new Run(row.Row.ItemArray[j].ToString()))));
}
else
{
r.Cells.Add(new TableCell(new Paragraph(new Run(row.GetType().GetProperty(bindList[j]).GetValue(row, null)))));
}
r.Cells[j].ColumnSpan = 4;
r.Cells[j].Padding = new Thickness(4);
r.Cells[j].BorderBrush = Brushes.DarkGray;
r.Cells[j].BorderThickness = new Thickness(0, 0, 1, 1);
}
tableRowGroup.Rows.Add(r);
table.RowGroups.Add(tableRowGroup);
}
fd.Blocks.Add(table);
printDialog.PrintDocument(((IDocumentPaginatorSource)fd).DocumentPaginator, "");
}
}
}
Step2: Then go to print button click event and create object of PrintDG class then call printDG pass to It two parameters datagridname and title.
Like :
private void print_button_Click(object sender, RoutedEventArgs e)
{
PrintDG print = new PrintDG();
print.printDG(datagridName, "Title");
}
If any error occurs during execution tell me and I will solve It.This is running code only, you need copy and paste.
Edited:
I declared row as dynamic. The dynamic keyword decides at run time which type to instantiate, either DataTable or another.
I work with This :

I am doing C# application, and I want to change the style of a message box. Is it possible or not?
Example: change button style, fore color, etc.
You can't restyle the default MessageBox as that's dependant on the current Windows OS theme, however you can easily create your own MessageBox. Just add a new form (i.e. MyNewMessageBox) to your project with these settings:
FormBorderStyle FixedToolWindow
ShowInTaskBar False
StartPosition CenterScreen
To show it use myNewMessageBoxInstance.ShowDialog();. And add a label and buttons to your form, such as OK and Cancel and set their DialogResults appropriately, i.e. add a button to MyNewMessageBox and call it btnOK. Set the DialogResult property in the property window to DialogResult.OK. When that button is pressed it would return the OK result:
MyNewMessageBox myNewMessageBoxInstance = new MyNewMessageBox();
DialogResult result = myNewMessageBoxInstance.ShowDialog();
if (result == DialogResult.OK)
{
// etc
}
It would be advisable to add your own Show method that takes the text and other options you require:
public DialogResult Show(string text, Color foreColour)
{
lblText.Text = text;
lblText.ForeColor = foreColour;
return this.ShowDialog();
}
MessageBox::Show uses function from user32.dll, and its style is dependent on Windows, so you cannot change it like that, you have to create your own form
Here is the code needed to create your own message box:
