CheckBoxClick event or CurrentCellChanged event

Here is the scenario and I am not sure which event (CheckBoxClick or CurrentCellChanged) is the right one to use. I have a grid control that has two check boxes. These check boxes suppose to do totally different things. When click in one of them it suppose to display two hidden columns and the other one suppose to change some coloring. CheckBoxClick event is for grid therefore I need to know which checkbox has changed to do the proper action. I thought of CurrentCell.RowIndex and CurrentCell.ColIndex. But for first time when I click on the checkbox the RowIndex and ColIndex returns -1, -1. The second time it returns the correct position. How can I fix this? Should I use CurrentCellChanged instead?

What kind of grid are you using? Why can you not use gridControl1.CheckBoxClick or gridGroupingControl1.TableControlCheckBoxClick or gridDataBoundGrid1.CheckBoxClick?

I am using GridControl. When I said CheckBoxClick event I meant the same as gridControl1.CheckBoxClick. Since I have two check boxes I need to know which checkbox has been checked by user. Therefore I need to know the row and column of the checkbox. I found out how I can get the row and column. I used e.RowIndex and e.ColIndex. private void _WorksheetGrid_CheckBoxClick(object sender, GridCellClickEventArgs e) { GridStyleInfo style; GridControl grid = sender as GridControl; if (grid != null) { if (e.RowIndex == 1 && e.ColIndex ==5 ) //Show Prefault { .... } if (e.RowIndex == 14 && e.ColIndex == 11 ) { ... } ... }

Actually, Clay, Najmeh''s question raises an important question - is there something broken about the CurrentCellChanged event w/r/t checkboxes?? Inside that event, I am seeing what seems to be inconsistent behavior. If the cell firing the event is a textbox, grid.CurrentCell().GetRenderer().GetCellValue() returns the correct "new value" in the text box. If, however, the cell that changed is a checkbox, GetRenderer().GetCellValue() ~always~ returns true. Could this be correct?

This is actually by design. The CheckBox CellType is special. It has no active cell control and the checkbox is drawn in a static manner. There is no Control used to render this cell. The values are immediately stored in the grid as they are changed. Here is code that shows how to get this current value in CurrentCellChanged.

private void gridControl1_CurrentCellChanged(object sender, EventArgs e)
{
	GridCurrentCell cc = this.gridControl1.CurrentCell;
	if(this.gridControl1[cc.RowIndex, cc.ColIndex].CellType == "CheckBox")
	{
		Console.WriteLine(this.gridControl1[cc.RowIndex, cc.ColIndex].CellValue);
	}
}

Clay, Thanks for confirming this behavior is by design. I had already figured out to use grid[r,c].cellvalue - but I wasn''t sure this was by intent, or just a convenient hack. -ralph
