I have a GridView dynamically bind with database table.  I use TemplateField to create a CheckBox in each column's footer.  I added EventHandler when CheckedChanged for each CheckBox.  When user clicks CheckBox, I want to change color of entire column.   How do I get cell index when a CheckBox is clicked by user in CheckedChanged EvenHandler?

Type cast sender to CheckBox and access the Parent property and that would give you the cell. You can go from there.

GridViewRow Row = ((GridViewRow)((Control)sender).Parent.Parent);

GridViewColumn Col = (GridViewColumn)((Control)sender.Parent)

GridViewColumn is Windows control.  I am using ASP .NET and I can't cast sender to GridViewColumn.  This is what I got stuck.

I ended up get clicked CheckBox control and compare with each cell's CheckBox to get column number.
