Disable selection for rows + additional issue

[Markus]

Hello!

I managed to disable the selection for some rows according to this link:
http://www.telerik.com/community/code-library/submission/b311D-tmkbk.aspx

My Problem is the following:
When clicking the checkbox in the header (select all items) all items except the ones that are disabled are checked --> as expected.
The Problem: The Checkbox in the header does not stay checked.
That means that i cannot deselect all selected items.

Can you provide a solution for this problem.

thx in advance

Hi Markus,

Thank you for the observation. You can explicitly check the select all checkbox in the Selecting event of the last data row in RadGrid. Simply modify your Selecting event in the following way:

function Selecting (sender, args)
{
    var i = 0;
    while(typeof(a[i]) != "undefined")
    {
        if (a[i++] == args.get_itemIndexHierarchical())
        {
            args.set_cancel(true);
        }
    }

    var chkAll = sender.get_masterTableView().HeaderRow.cells[0].childNodes[0];
    var index = args.get_itemIndexHierarchical();
    var maxIndex = sender.get_masterTableView().get_dataItems().length-1

    if(index == maxIndex)
        chkAll.checked = true;
}
