Hello,

I am having a problem when writing to the row header when I use the following line of code:
" this._grid[i, 0].CellValue = rowCount.ToString(); "

I'm simply trying to programmaticaly enumerate this column(0) with a number. But when I make a call to the CellValue, my rowIndex is returned as out of range and an exception is thrown.

i = 2
grid.RowCount = 8

Is there a reason why my grid is upset with accessing this row?

Thanks in advance.

You can try handling the PrepareViewStyleInfo event of the grid to get numbered row headers.


private void gridControl1_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
if (e.ColIndex == 0 && e.RowIndex > 0)
{
e.Style.Text = e.RowIndex.ToString();
e.Style.BaseStyle = "Header";
e.Style.Font.Bold = false;
}
}

Here is a small sample for reference.

Please let me know if this serve your needs.

Regards,
Nisha

Nisha,

Thanks for the reply. I'm building a grid which populates with vector data. Vector data is not always a 1:1 association so numbering row columns this way is not ideal. I have a separate method in which the code above is throwing an exception... the debug window I have says that it's a Syncfusion ... SetItem() method that is throwing an error.

Any Ideas?
