Hi, I'm using VS2012.
In the row updating event, I need to see if user checked the checkbox.  In the gridview, 1st column is the auto generated Edit.  4 columns to the right is my checkbox column.  What index should I use, 4?  (edit button is 1?)  and code like this?
 dt.Rows[row.DataItemIndex]["IsComplete"] = ((CheckBox)(row.Cells[4].Controls[0])).Checked;

Also, what is the Controls[0]?  What index is it referring to with 0?

Thank you.

If this is a checkbox column the value to check is TrueValue/FalseValue
http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcheckboxcell(v=vs.110).aspx

so use something like

DataGridViewCheckBoxCell cell = (DataGridViewCheckBoxCell)row.Cells[4].Value
if (cell.Value == cell.FalseValue || cell.Value == null)
            {
                // Action if false
            }
            else
            {
                //Action if true;
            }

Open in new window


Not sure where you got your code from but I would guess in this case that this is the zero based collection of controls in the cell and since the only only control in the cell is the check box you call index 0 to get this checkbox.
