[CLOSED] CheckboxSelection model from codebehind --> Check all checkbox in header

[CarWise]

Hi,

When checking all checkboxes in a grid from codebehind like this:

 RowSelectionModel sm = gpUitrusting.SelectionModel.Primary as RowSelectionModel;
                    foreach (DataRow dr in dtCheckedUitrusting.Rows) sm.SelectedRows.Add(new SelectedRow(Conversie.ToString(dr["nUitrustingid"])));

The "check all" checkbox in the header stays unchecked when i'm in a situation that all rows are check. Is there a way to accomplish that ? (it works clientside)

Hi,

I would suggest you to use CheckboxSelectionModel's .SelectAll() method. It works fine.

Example

(this.GridPanel1.GetSelectionModel() as CheckboxSelectionModel).SelectAll();

Could you provide testable sample reproducing the issue? Header checks must be checked also where all rows checkboxes are checked.
