How to get all the controls inside a specific cell in a GridView

Question

I am generating CheckBox controls dynamically inside a GridView. Now i need to validate if atleast one CheckBox is selected and also while saving data i need to iterate through all the controls inside the cell.

Now the issue is i cannot do grdApproverDetails.Rows[i].FindControl('controlID'), because the ID's are dynamically generated based on the control count. As shown in this thread.

This is how the GridView looks and Approver Name is the column inside which i need to find controls, if CheckBoxes.

How can i get all the controls inside a GridView cell and iterate through?

Answer 1

You can get checkboxes using (handwritten code):

foreach (GridViewRow row in grdApproverDetails.Rows)
{
    for (int k = 0; k < row.Cells.Count; k++)
    {
       for (int i = 0; i < row.Cells[k].Controls.Count; i++)
       {
           Control control = row.Cells[k].Controls[i];
           if(control is CheckBox)
           {
               CheckBox chk = control as CheckBox;
               if(chk != null && chk.Checked)
               //...
           }
       }
    }
}
