GridClientSelectColumn - How do I get checked state of header checkbox?

[Jason Maronge]

I have a GridClientSelectColumn with the Checkbox in the header that selects the row in the grid.  The question I have is how do I tell if the checkbox in the header is checked.  The problem I am having is that my grid is paged and the SelectedItems collection only contains the current page of items.  I need to know if they header checkbox was selected so I can delete all the records in the grid.

Thanks,

Jason

Hi Jason,

Try the following code snippet for getting the reference to checkbox in header.

CS:

foreach (GridHeaderItem headerItem in RadGrid1.MasterTableView.GetItems(GridItemType.Header))
{
    CheckBox chk = (CheckBox)headerItem["selectAll"].Controls[0]; // Get the header checkbox
}

Thanks,
Shinu.
