Selecting Values in a DataGrid, via a checking a CheckBox

Hello, I am fairly new to C# and .NET. I am trying to select values in a DataGrid on a Button_Click event, if that particular row has a CheckBox checked. There 3 columns in my DataGrid, startTime, endTime which are both databound and a checkbox column which is not. Then these values will be passed in to by sql 2000 DB. This is what I have done so far….. private void Button_Click(object sender, System.EventArgs e) { int i = 0; CheckBox cb; foreach (DataGridItem dgi in this.DataGrid1.Items) { cb = (CheckBox) dgi.Cells[0].Controls[1]; if(cb.Checked) { //Not too sure what to do here, but no idea if the above works? } i++; } } Could some please help, any help would be much appreciated. I would like to do this in the code behind aspx.cs Thanks, Tom
