Hi,

I am using the sample code from "DropdownGrid_2008" to play around and trying to add headers to the drop down grid.

this is the code snippet:

this.GridB.GridVisualStyles = Syncfusion.Windows.Forms.GridVisualStyles.Office2007Blue;
this.GridB.Properties.BackgroundColor = System.Drawing.Color.FromArgb(((System.Byte)(227)), ((System.Byte)(239)), ((System.Byte)(255)));
this.GridB.Properties.GridLineColor = System.Drawing.Color.FromArgb(((System.Byte)(208)), ((System.Byte)(215)), ((System.Byte)(229)));
this.GridB.DefaultGridBorderStyle = GridBorderStyle.Solid;
this.GridB.ForeColor = System.Drawing.Color.MidnightBlue;
this.GridB.Font = new System.Drawing.Font("Verdana", 8.5F);
string[] header = new string[6];
header[0] = "Stephen";
header[1] = "Kenneth";
header[2] = "Nancy";
header[3] = "Ivy";
header[4] = "Clara";
header[5] = "Paddy";
this.GridB.Model.PopulateHeaders(GridRangeInfo.Cells(0, 1, 0, 6), header);


I thought it is pretty simple but this does not work. Can you tell me what's wrong?

thanks

Hi Stephen,

Thank you for your interest in Syncfusion product.

The PopulateHeader method used to populate the Header depends upon the DataSource.

Refer the example code below:

// BindingListDatsource
IList list = new List();
for (int i = 1; i <=100; i++)
{
list.Add(new Foo("Syncfusion","Syncfusion"));
}
foos = new BindingList(list);
GridB.RowCount = foos.Count;
GridB.ColCount = 2;
GridB.PopulateHeaders(GridRangeInfo.Cells(0, 1, 0, 2), foos);
GridB.PopulateValues(GridRangeInfo.Cells(1, 1, gridControl1.RowCount, gridControl1.ColCount), foos);

// DataTable DataSource
DataTable dt = GetTable();
GridB.RowCount = dt.Rows.Count;
GridB.ColCount = dt.Columns.Count+1;
GridB.PopulateHeaders(GridRangeInfo.Cells(0, 1, 0, dt.Columns.Count), dt);
GridB.PopulateValues(GridRangeInfo.Cells(1, 1, gridControl1.RowCount, gridControl1.ColCount), dt);


If you want to set the HeaderText in GridControl, then please try using Text porperty in GridStyleInfo to achieve this behavior.

Refer the code below:

GridB[0,1].Text="Header1"; // Set the Header text for First header cell
GridB[0,2].Text="Header2";


Please let me know if you have any queries.

Regards,
Lingaraj S.

This works only up to 10 columns. After 10 columns there are no names.
How to fix that?
