How I can loop through all row of my grid and detect only row with checkbox column checked ?

i use this solution and got error :  

-------------------------------------------------------------------------------------------------------

Error:

"System.NullReferenceException: 'Object reference not set to an instance of an object.'Telerik.WinControls.UI.GridViewCellInfo.Value.get returned null."
-------------------------------------------------------------------------------------------------------

Code:

IList<GridViewRowInfo> gridRows = new List<GridViewRowInfo>();
foreach (GridViewRowInfo rowInfo in radGridView.ChildRows)
{
    bool isChecked = (bool)rowInfo.Cells["CheckboxColumn"].Value;
    if (isChecked == true)
    {
        gridRows.Add(rowInfo);
    }
}

Hello,

Your question has already been answered in the thread (Ticket ID: 1445891) you have opened on the same topic. Please, see our answer there for more information.

We kindly ask you to use just one thread for a specific problem to contact us. Posting the same questions numerous times slows down our response time because we will need to review and address two or more tickets instead of one. Moreover, threads are handled according to license and time of posting, so if it is an urgent problem, we suggest you use a support ticket, which would be handled before a forum thread.

Thank you for your understanding.

Regards,
Nadya
