in windows forms controls in tabpage increments by one when tabpage is recreated

In my windows form I create a tabpage and added controls to them. But when I close a particular tabpage and reopen it then the controls in it are incremented by one.
I mean to say, I only want to display one panelbox in tabpage when I close it and reopen it. the tabpage contains two panels.
Here is the code:
//onButtonClickEvent
TabPage tab1 = new TabPage();
tab1.Name = "CriminalRecord";
tab1.Text = "Criminal Record".ToString();
tab1.Visible = true;
tab1.BackColor = Color.Brown;
if (tabControl1.TabPages.Count != 0)
{
for (int i = 0; i <= tabControl1.TabCount; i++)
{
if (tabControl1.TabPages.Contains(tab1))
{
tabControl1.SelectTab(tab1);
}
else
{
tabControl1.Controls.Add(tab1);
tab1.Controls.Add(loadPanelBottom());
tab1.Controls.Add(loadPanel());
tab1.Controls.Add(loadPanelTop());
}
}
}
else
{
tabControl1.Controls.Add(tab1);
tab1.Controls.Add(loadPanelBottom());
tab1.Controls.Add(loadPanel());
tab1.Controls.Add(loadPanelTop());
}
Splitter loadPanel()
{
Splitter splitter1 = new Splitter();
splitter1.BackColor = SystemColors.ControlDarkDark;
splitter1.Cursor = Cursors.HSplit;
splitter1.Dock = DockStyle.Top;
splitter1.Location = new System.Drawing.Point(0, 0);
splitter1.Name = "splitter1";
splitter1.Size = new System.Drawing.Size(100, 5);
splitter1.TabIndex = 1;
return splitter1;
}

You should declare new tabpage into the form class
example
public partial class main:form
{
TabPage tab1;
}
and then
//onButtonClickEvent
TabPage tab1 = new TabPage();
tab1.Name = "CriminalRecord";
tab1.Text = "Criminal Record".ToString();
tab1.Visible = true;
tab1.BackColor = Color.Brown;

How to Change Content of Button if it is a child of a grid?

I want to change content of button1 on click event of button2 . But not able to get the object of grid's child Button class which is in List<> UiList.
Please Guide me in getting the right approach to look it and solve it . And also guide that if the object is build in runtime then how to access it ?
public partial class MainPage : PhoneApplicationPage
{
List<Grid> UIList = new List<Grid>();
Grid objGrid1 = null;
Button objButton1 = null;
Button objButton2 = null;
// Constructor
public MainPage()
{
InitializeComponent();
createGrid1("grid1");
createButton2("Button2");
}
public void createGrid1(string x)
{
objGrid1 = new Grid();
objGrid1.Height = 100;
objGrid1.Name = x;
objGrid1.Width = 200;
objGrid1.Margin = new Thickness(100, 100, 0, 0);
objGrid1.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
objGrid1.VerticalAlignment = System.Windows.VerticalAlignment.Top;
objGrid1.Background = new SolidColorBrush(Colors.Orange);
createButton1("changename");
}
public void createButton1(string _name)
{
objButton1 = new Button();
objButton1.Height = 90;
objButton1.Name = _name;
objButton1.Content="Button1";
objButton1.FontSize = 20;
objButton1.Width = 190;
objButton1.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
objButton1.VerticalAlignment = System.Windows.VerticalAlignment.Top;
objButton1.Background = new SolidColorBrush(Colors.Blue);
objButton1.Foreground = new SolidColorBrush(Colors.White);
objGrid1.Children.Add(objButton1);
LayoutRoot.Children.Add(objGrid1);
UIList.Add(objGrid1);
}
public void createButton2(string _name)
{
objButton2 = new Button();
objButton2.Margin = new Thickness(240, 300, 0, 0);
objButton2.Name = _name;
objButton2.Height = 90;
objButton2.Content = "Button2";
objButton2.FontSize = 20;
objButton2.Width = 190;
objButton2.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
objButton2.VerticalAlignment = System.Windows.VerticalAlignment.Top;
objButton2.Background = new SolidColorBrush(Colors.Blue);
objButton2.Foreground = new SolidColorBrush(Colors.White);
LayoutRoot.Children.Add(objButton2);
objButton2.Click += (s, e) =>
{
int c = UIList.ElementAt(0).Children.Count;
if (c == 1)
{
//logic to change content of Button1 on click of Button2
}
};
}
}

Assuming you cannot just keep a reference to the created control, such as in a class field, you can iterate through the Children property of the Grid and find the desired Button. If there are multiple buttons, you can differentiate them using the Tag property.
Once you find it, change the contents of the button using the Content property, as discussed in the contents above.

dynamically creating window form according to data returned from dataset (C#)

I have a dataset that returns questions and answers from the database, each answer in answer table is linked via a forgein key to the question table.
What I would like to achive is the following:
That a a single dynamic form is created on the first question with all the questions listed under it, meaning the FK_table_Answers = PK_table_Questions on the table_Answers:
(eg) This is Form for Question One:
Question One: How old are you?
Answer One (this is a radio button)
Answer Two (this is a radio button)
Answer Three (this is a radio button)
I have managed to get the above kind of working but the problem is my code keeps generating the forms (eg) 3 times becuase there are three answers, so can anyone point me in right direction how to generate the form dynamically but only ONCE - meaning each successive form is created only once as per the question and that particular questions answers under it.
Kind regards

private void CreateBoxAndQuestion(Form f, Panel p, Label l)

for (int i = p.Controls.Count - 1; i >= 0; i--)
{
p.Controls.RemoveAt(i);
}
}

If I understand correctly, you call CreateBoxAndQuestion every time a new question is selected.
But you create (and destroy) the form each time your code enters in this method.
A first approach would be to keep the form, label, button and panel creation outside the method (perhaps in design mode) then passing these controls to the method as
EDIT: Somewhere in your code before entering the load of your next question:
frmQuestion _form = null; // Global
// Create a global instance and keep it without displaying
if(_form == null) _form = new frmQuestion(); // frmQuestion created with panel, label e button via FormDesigner
then when you need to populate _form call
CreateBoxAndQuestion(_form, _form.Panel, _form.Label, questionText);
In this example I pass the _form to CreateBoxAndQuestion, but this is not necessary because is a global. You could change CreateBoxAndQuestion to use directly the global instance.
private void CreateBoxAndQuestion(frmQuestion f, Panel p, Label l, string _label)
{
// Do not display your form here....
}
Now when entering the method clear every RadioButton controls in the panel.Controls collection
for (int i = p.Controls.Count - 1; i >= 0; i--)
{
p.Controls.RemoveAt(i);
}
the rest of the code should change only to reflect the new text assigned to the label and controls and the re-adding of the RadioButtons to the panel. No more creation and reinitialization for Form Label, Button.
label.Text = _label;
Don't forget to destroy _form at the end of your program with _form.Dispose();

Show Dialog box at center of its parent

It's been a mess to show a DialogBox at the center of its parent form. Here is a method to show a dialog.
I am positioning its parent to center but not able to center the DialogBox
private void OpenForm(Object point, Object height, Object width)
{
FormLoading frm = new FormLoading();
Point temp = (Point)point;
Point location = new Point(temp.X + (int)((int)width) / 2,
temp.Y + (int)((int)height) / 2);
frm.Location = location;
frm.ShowDialog();
}
private void btnView_Click(object sender, EventArgs e)
{
try
{
ThreadStart starter= delegate { OpenForm(currentScreenLocation,
this.Height, this.Width); };
Thread t = new Thread(starter);
t.Start();
////// Some functionality here...
t.Abort();
}
catch (Exception)
{
}
}

You might want to check the Form.StartPosition property.
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.startposition.aspx
something along the lines of:
private void OpenForm(Form parent)
{
FormLoading frm = new FormLoading();
frm.Parent = parent;
frm.StartPosition = FormStartPosition.CenterParent;
frm.ShowDialog();
}
This of course requires setting the form's parent.

form1.StartPosition = FormStartPosition.CenterScreen;
See http://msdn.microsoft.com/en-us/library/system.windows.forms.form.startposition(v=vs.110).aspx

if you are making a custom MessageBox,you can simply put this:
CenterToParent();
in your custom MessageBox formload() method.

In addition, if you want to set up arbitrary location you can use this
FormLoading frm = new FormLoading();
Point location = new Point(300, 400);
frm.StartPosition = System.Windows.Forms.FormStartPosition.Manual;
frm.Location = location;
frm.ShowDialog();

NewForm.Show();
NewForm.Top = (this.Top + (this.Height / 2)) - NewForm.Height / 2;
NewForm.Left = (this.Left + (this.Width / 2)) - NewForm.Width / 2;

Custom Message Box

Is it possible to create my own custom MessageBox where I would be able to add images instead of only strings?

I also wanted this feature, so I created WPFCustomMessageBox, a WPF clone of the native Windows/.NET MessageBox which supports extra features like custom button text.
WPFCustomMessageBox uses static methods just like the standard .NET MessageBox, so you can plug-and-play the new library without modifying any code. Most importantly, I designed this control so it looks identical to the original MessageBox.
I created this library because I wanted to use verbs for my MessageBox buttons to help users better understand the functionality of the buttons. With this library, you can offer your users button descriptions like Save/Don't Save or Eject Fuel Rods/Don't do it! rather than the standard OK/Cancel or Yes/No (although you can still use those too, if you like).
The WPFCustomMessageBox message boxes return standard .NET MessageBoxResults. It also offers the same features as the original MessageBox like MessageBoxIcons and custom message box captions.
WPFCustomMessageBox is open source, so you can grab the code or make improvements here: https://github.com/evanwon/WPFCustomMessageBox
You can add WPFCustomMessage to your project via NuGet: https://www.nuget.org/packages/WPFCustomMessageBox/

Here is the code needed to create your own message box:

I've implemented a WPF MessageBox fully customizable via standard WPF control templates:
http://blogs.microsoft.co.il/blogs/arik/archive/2011/05/26/a-customizable-wpf-messagebox.aspx
Features
The class WPFMessageBox has the exact same interface as the current WPF MessageBox class.
Implemented as a custom control, thus fully customizable via standard WPF control templates.
Has a default control template which looks like the standard MessageBox.
Supports all the common types of message boxes: Error, Warning, Question and Information.
Has the same “Beep” sounds as when opening a standard MessageBox.
Supports the same behavior when pressing the Escape button as the standard MessageBox.
Provides the same system menu as the standard MessageBox, including disabling the Close button when the message box is in Yes-No mode.
Handles right-aligned and right-to-left operating systems, same as the standard MessageBox.
Provides support for setting the owner window as a WinForms Form control.

Sure. I've done it by subclassing System.Windows.Window and adding the capacity to show various kinds of content (images, text and controls), and then calling ShowDialog() on that Window:
public partial class MyMessageBox : Window
{
// perhaps a helper method here
public static bool? Show(String message, BitmapImage image)
{
// NOTE: Message and Image are fields created in the XAML markup
MyMessageBox msgBox = new MyMessageBox() { Message.Text = message, Image.Source = image };
return msgBox.ShowDialog();
}
}
In the XAML, something like this:
<Window>
<DockPanel>
<Image Name="Image" DockPanel.Dock="Left" />
<TextBlock Name="Message" />
</DockPanel>
</Window>

I was in need like you and I have found this source and modified the way I wanted and you could get the most benefit out of it
here is the link
this is what it looks like by default:
