GDBG checking all checkboxs in multi selected rows

[Administrator]

Hi,

i am using the GDBG with columns bound to a data set, one of the columns is a checkbox. I need to have the ability that when i select more then one row, clicking one of the selected checkboxs will check all the selected checkboxs and not only the clicked cell.

Hi Tzvika,

This can be done through the CurrentCellChanged event of the grid. Here is some code snippet.

// CurrentCellChanged event handler
GridCurrentCell cc = this.gridDataBoundGrid1.CurrentCell;
int top = this.gridDataBoundGrid1.Selections.Ranges.ActiveRange.Top;
int bottom = this.gridDataBoundGrid1.Selections.Ranges.ActiveRange.Bottom;

if(this.gridDataBoundGrid1.Selections.Ranges.AnyRangeContains(cc.RangeInfo))
{
    if(cc.Renderer.StyleInfo.CellType == "CheckBox")
    {
	bool check = (bool) cc.Renderer.StyleInfo.CellValue;
	if(check)
	{
	    for(int i = top ; i <= bottom ; i++)
	    {
		this.gridDataBoundGrid1.Model[i, cc.ColIndex].CellValue = true;
	    }
	}
    }
}

Here is a sample demonstrating this feature.
