displaying/editing with embedded tabs in databoundgrid

[James A Frisby(For EPS - Computer Software)]

I''m evaluating essential grid for a data project I''m working on. One problem I''ve found, occurs when text in the database contains embedded tab characters.

After the data is loaded into the grid, i run the .Model.RowHeights.ResizeToFit process on the grid.

When the text is presented in the grid, each tab takes a single space, however when you click in the cell to edit it, the tabs expand to read correctly.

Is there a way to set the grid so it shows the tabs expanded at display time as well as during cell edit?

Thanks

There is no property setting to handle this.

One thing you can do is to handle the DrawDisplayText event and draw the text yourself in a way that shows the tabs. For example, you can draw it as Richtext.

private RichTextBox rtb = new RichTextBox();
private void gridDataBoundGrid1_DrawCellDisplayText(object sender, GridDrawCellDisplayTextEventArgs e)
{
	if(e.Style.CellIdentity.ColIndex == 2) //use for column 2
	{
		rtb.Clear();
		rtb.SelectedText = e.DisplayText;
		string rtf = rtb.Rtf;
		Syncfusion.Drawing.RichTextPaint.DrawRichText(e.Graphics, rtb, rtf, this.gridDataBoundGrid1.PrintingMode, this.gridDataBoundGrid1.GridBounds, e.TextRectangle, 
this.gridDataBoundGrid1.GridBounds, e.Style.BackColor, e.Style.WrapText, 100, false);
		e.Cancel = true;
	}
}

Depending upon the version of the grid you are using, the DrawRichText method shown above may give a syntax error. If so, try removing the last argument.

Clay,
Your suggestion makes the tabs show correctly, but curiously, since I''m using "Model.RowHeights.ResizeToFit", it now formats the height such that the last line of the text doesn''t show anymore.

I do not have a simple solution for this problem. The sizing algorithm is using the same strings as the orignal problem you described, and thus, does not use the tab in the string.

Ok, thanks
