ComboBox Selected Value

[Bernard Herrok]

Hi,

I have a databound grid with a cell which is of type combobox (bound to another dataset).

I''d like to set the next 2 cells enabled/disabled according to the selection of the combobox.

e.g. if combobox is "Next Year" then the next 2 cells are disable if it''s "Base Year" then the next 2 cells are enabled.

Thanks in advanced.

Try handling the grid.Model.QueryCellInfo event.

In your handler, if e.RowIndex > 0 and if e.ColIndex points to one of the ''next two cells'' you mentioned, then get the value of the comboxcell and set e.Style.Enabled accordingly.

private void Model_QueryCellInfo(object sender, GridQueryCellInfoEventArgs e)
{
	if(e.RowIndex > 0)
	{
		if(e.ColIndex == this.grid.Binder.NameToColIndex("NextCol1")
			|| e.ColIndex == this.grid.Binder.NameToColIndex("NextCol2"))
		{
			int col = this.grid.Binder.NameToColIndex("ComboCol");
			string val = this.grid[e.RowIndex, col].Text; //may want .FormattedText
			if(val == "NextYear")
				e.Style.Enabled = true;
			else
				e.Style.Enabled = false;
		}
	}
}
