Stack overflow exception using QueryColWidth

I''m using the following code in the QueryColWidth event of a data bound grid. if (e.Index == 2) { int width = this.gridDocuments.Model.ColCount <= 0 ? 0 : (this.gridDocuments.Model.ColWidths.GetTotal(0, this.gridDocuments.Model.ColCount-1)-this.gridDocuments.Model.Cols.Size[2]); e.Size = this.gridDocuments.ClientRectangle.Width-width; e.Handled = true; } The intent (based upon postings in this forum) is to resize the second column based on the widths of the other column. The example this is borrowed from was intended to resize the last column. I want to resize a column in the middle of the other columns. The problem is that this results in a stack overflow exception in the grid. If I change the code to use the last column in the grid it works fine.

You cannot try to reference this.gridDocuments.Model.Cols.Size[2]); from within the code when e.Index = 2. The reason is that trying to retrieve this.gridDocuments.Model.Cols.Size[2]) trigeers a call to QueryColWidth with e.Index = 2. So, you get into a recursive call situation which leads to teh stack overflow. So, instead of int width = this.gridDocuments.Model.ColCount <= 0 ? 0 : (this.gridDocuments.Model.ColWidths.GetTotal(0, this.gridDocuments.Model.ColCount-1)-this.gridDocuments.Model.Cols.Size[2]); try

if(e.Index == 2)
{
	int width = this.gridDocuments.Model.ColWidths.GetTotal(0, 1);
	if(this.gridDocuments.Model.ColCount > 2)
		width += this.gridDocuments.Model.ColWidths.GetTotal(3,this.gridDocuments.Model.ColCount);
	e.Size = this.gridDocuments.ClientRectangle.Width - width;
	e.Handled = true;
}
