How can I set the number of copies equal to the amount in DataGridView

I have a Datagridview which is connected with excel sheets. My Excel sheet is a good receipt which contains the quantity of the items. Now i want to print labels as much as the amount. E.g if i have 10 T shirts, i want to print 10 labels with a 1 in quantity.
I've already tried the following code.
private void btnSingle_Click(object sender, EventArgs e)
{
BindingList<LableClass> GoodReceipt= new BindingList<LableClass>();
GoodReceipt.Add(new LableClass()
{
Charge = dataGridView1.SelectedCells[0].Value.ToString(),
ItemNr= dataGridView1.SelectedCells[1].Value.ToString(),
Description= dataGridView1.SelectedCells[2].Value.ToString(),
Quantity= float.Parse(dataGridView1.SelectedCells[8].Value.ToString())
});
LableClassBindingSource.DataSource = GoodReceipt;
PrinterSettings prtSetting = new PrinterSettings();
foreach (PaperSize item in prtSetting.PaperSizes)
{
if (item.PaperName == "62mm x 29mm")
prtSetting.DefaultPageSettings.PaperSize = item;
}
PageSettings ps = new PageSettings(prtSetting);
ps.Landscape = false;
ps.Margins.Top = 8;
ps.Margins.Bottom = 0;
ps.Margins.Left = 6;
ps.Margins.Right = 0;
PrintDocument prtDoc = new PrintDocument();
prtDoc.PrinterSettings = prtSetting;
prtSetting.Copies = 5;
prtSetting.FromPage = 1;
prtSetting.ToPage = 5;
reportViewer1.SetPageSettings(ps);
prtDoc.Print();
reportViewer1.RefreshReport();
}
I tried to print 5 labels for a test, but somehow all of them are empty. Sorry for bad english.

ASP.NET Charting - Y value doesn't start at 0

I'm working on a chart in asp.net that is dinamically created from a DataTable. Basically I've got a DataTable like this:
So, what I want in my chart is a column for each differente location, and for each diferent Type I want to have a "portion" of the column, meaning I would like to have a column per location divided per type.
I have managed to do something like this, but not quite what I would like:
Now I'll try to explain my code.
First, i add the different locations in my datatable to a list of strings
string loc = "";
for (int i = 0; i < dtTipos.Rows.Count; i++)
{
if (loc != dtTipos.Rows[i]["Location"].ToString())
listaLocais.Add(dtTipos.Rows[i]["Location"].ToString());
loc = dtTipos.Rows[i]["Location"].ToString();
}
After, for each different location, I select the rows to the corresponding location and create a series for each one of them. I proceed to create a point with y=0 and one with y=total
for (int i = 0; i < listaLocais.Count; i++)
{
DataRow[] lRow = dtTipos.Select("Location = '" + listaLocais[i] + "'");
foreach (DataRow dr in lRow)
{
string serie = dr["Location"].ToString().Substring(0, 2) + "_" + dr["Type"].ToString() + " - " + dr["Total"].ToString();
Series s = new Series();
s.Name = serie;
s.Label = dr["Location"].ToString();
s.ChartType = SeriesChartType.StackedColumn;
chartTipo1.Series.Add(s);
s.Points.AddXY(i + 1, 0);
s.Points[0].Label = " ";
s.Points.AddXY(i + 1,Convert.ToInt32(dr["Total"].ToString()));
s.Points[1].Label = " ";// dtTipos.Rows[i]["Total"].ToString();
}
}
The thing is: I think that because I create a serie for each row, everytime I use a diferent column, the y axis starts from where I left it.
Is there any way so I can get this to work?
I'll appreciate any help.

You're adding your series and data points in the same loop. First add your series, then your data points:
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new MyDataTable();
//first add your series
foreach (DataRow row in dt.DefaultView.ToTable(true, new string[] { "Type" }).Rows)
{
Series series = new Series();
series.Name = (string)row["Type"];
series.ChartType = SeriesChartType.StackedColumn;
Chart1.Series.Add(series);
}
// then add your points;
foreach (DataRow row in dt.Rows)
Chart1.Series[(string)row["Type"]].Points.AddXY(row["Location"], new object[] { row["Total"] });
}
}

How to display data from an array in a grid in WindowsForms - C#

I have a WindowsForms application that I am compiling as a DLL to be used by another program. This program supplies the DLL with an array filled with information(floats). What I want to do is display these numbers in an organized way(row and columns). The methods I've investigated so far incorporate the use of a DataGridView object, however I do not have a "database", I only have the raw data stored as an array.
Would the only way to do this involve creating a SQL database with my data from the array? Or is there an easier/faster way of doing this?

Thanks for the replies, but I just ended up looping through the creation of the rows and columns and filling them with my required data.
Creating/initializing DataGridView:
private System.Windows.Forms.DataGridView dataGridView1;
this.dataGridView1 = new System.Windows.Forms.DataGridView();
//Size and location can be changed to whatever you want
this.dataGridView1.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;
this.dataGridView1.Location = new System.Drawing.Point(12, 436);
this.dataGridView1.Name = "dataGridView1";
this.dataGridView1.RowHeadersWidth = 70; //Adjusts row header to fit entire "Score" string
this.dataGridView1.Size = new System.Drawing.Size(976, 398);
this.dataGridView1.TabIndex = 10;
Creating rows/columns and filling them with my data:
for (int i = 0; i <= 40; i++)
{
dataGridView1.Columns.Add("column" + i.ToString(), i.ToString());
dataGridView1.Columns[i].Width = 22;
}
DataGridViewRow row = (DataGridViewRow)dataGridView1.Rows[0].Clone();
for (int i = 0; i <= 40; i++)
{
row.Cells[i].Value = scores[0,i]; // "scores" is an Int32[,] array filled with my data
}
dataGridView1.Rows.Add(row);
dataGridView1.Rows[0].HeaderCell.Value = "Score";
The result looked something like this.

You can send the gridview data in XML format
private void Form1_Load(object sender, EventArgs e) {
DataSet ds = new DataSet();
ds.ReadXml(#"XMLFile1.xml");
gridControl1.DataSource = ds.Tables[1];
gridView1.PopulateColumns();
}

Infragistics XamDataChart - Column X Labels - half showing up

As you can clearly see the XAMDataChart is skipping putting the label on every other column.
I have no clue why this is happening. The code is the same for all of them and I have verified that the data is there.
Here is how they are generated
CategoryXAxis catX = new CategoryXAxis();
NumericYAxis numY = new NumericYAxis();
foreach (var series in control.masterCollection)
{
catX.Name = "catX";
catX.ItemsSource = series;
catX.Label = "{Label}";
catX.Gap = 20;
numY.Name = "numY";
ColumnSeries cs = new ColumnSeries()
{
ItemsSource = series,
ValueMemberPath = "YPoint",
XAxis = catX,
YAxis = numY
};
}

The answer to this question is setting the Category X Axis objects interval to 1.
catX.Interval = 1;

Issues using 2 axis labels with RadBarChart and no Gap between bars

I have 2 problems:
I want the names from the datatable but it is showing me in numeric form.
I would like a gap between the two bars but I can't find a way.
Here is the code:
private void InitializeGraph (DataTable poDt)
{
Telerik.Charting.ChartSeries chartseries = new Telerik.Charting.ChartSeries();
try
{
chartseries.Type = Telerik.Charting.ChartSeriesType.Bar;
Telerik.Charting.ChartSeriesItem csItem;
RadChart1.PlotArea.XAxis.AutoScale = true;
RadChart1.PlotArea.XAxis.DataLabelsColumn = "Name";
for (int iRow = 0; iRow < poDt.Rows.Count; iRow++)
{
chartseries = new Telerik.Charting.ChartSeries();
chartseries.Type = Telerik.Charting.ChartSeriesType.Bar;
chartseries.Name = poDt.Rows[iRow]["Name"].ToString().Trim();
csItem = new Telerik.Charting.ChartSeriesItem();
csItem.Name = poDt.Rows[iRow]["Name"].ToString();
csItem.Label.TextBlock.Text = poDt.Rows[iRow]["Value"].ToString();
RadChart1.PlotArea.XAxis.Appearance.TextAppearance.AutoTextWrap = Telerik.Charting.Styles.AutoTextWrap.True;
csItem.YValue = Int32.Parse(poDt.Rows[iRow]["Value"].ToString());
chartseries.AddItem(csItem);
RadChart1.Series.Add(chartseries);
}
RadChart1.PlotArea.XAxis.AddRange(1, poDt.Rows.Count, 1);
RadChart1.PlotArea.XAxis[poDt.Rows.Count].TextBlock.Text = chartseries.Name;
poDt.Rows.Count.ToString();
RadChart1.PlotArea.XAxis.AutoShrink = false;
RadChart1.PlotArea.XAxis.AutoShrink = true;
RadChart1.Series.Add(chartseries);
RadChart1.PlotArea.Appearance.Border.Visible = false;
RadChart1.Appearance.Border.Visible = true;
RadChart1.PlotArea.YAxis.IsLogarithmic = true;
RadChart1.PlotArea.YAxis.AutoScale = true;
RadChart1.PlotArea.YAxis.Appearance.ValueFormat=Telerik.Charting.Styles.ChartValueFormat.Number;
RadChart1.Appearance.BarWidthPercent = 50;
RadChart1.Chart.Appearance.FillStyle.MainColor = System.Drawing.Color.Red;
RadChart1.Chart.Appearance.FillStyle.MainColor = System.Drawing.Color.Transparent;
RadChart1.Legend.Appearance.FillStyle.MainColor = System.Drawing.Color.Transparent;
}
catch (Exception Ex)
{
//throw;
}
finally
{
poDt.Clear();
poDt = null;
chartseries = null;
}
}

Sorry, I do not believe there is a way to display two X-axis at the same time.
My suggestion is you use a CategoricalAxis for your X axis and create a custom bar chart that has a legend which differentiates the two values. I don't have any working samples, however you can use this Telerik Silverlight demo for starters.
Also, switch to RadChartView if you can. Because I would then suggest an easier approach, which is using a Categorical X-Axis and create multiple Y axes. If you go that route, you can do something like this for a DateTimeContinuous (or Categorical) X-axis with multiple Y-axes :
int count = 0;
LineSeries lineSeries = new LineSeries();
lineSeries.CategoryBinding = new PropertyNameDataPointBinding() { PropertyName = "TimeStamp" };
lineSeries.ValueBinding = new PropertyNameDataPointBinding() { PropertyName = "Value" };
lineSeries.VerticalAxis = new LinearAxis()
{
Title = "Title Here"
};
lineSeries.ItemsSource = yourCollection.Values;
//First Y-axis to be placed on the left of X-axis,
//additional Y-axes to be placed on right
if (count > 0 )
{
lineSeries.VerticalAxis.HorizontalLocation = Telerik.Charting.AxisHorizontalLocation.Right;
}
count++;
chartName.Series.Add(lineSeries);
Hope this helps.
