Hi BIshara,

In order to select multiple rows without the GridClientSelectColumn, the user have to hold the "CTRL" key (the common approach for multiple selection). However, if you need to enable multiple selection without the "CTRL" key you could use the following approach to override the built-in behavior:
<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        var targetSelectItem;
 
        function rowClick(sender, args) {
            targetSelectItem = args.get_gridDataItem();
            if (targetSelectItem.get_selected()) {
                setTimeout(function () {
                    targetSelectItem.set_selected(false);
                })
            }
        }
 
        function rowDeselecting(sender, args) {
            if (args.get_gridDataItem().get_itemIndexHierarchical() != targetSelectItem.get_itemIndexHierarchical()) {
                args.set_cancel(true);
            }
        }
    </script>
</telerik:RadCodeBlock>
 
<telerik:RadGrid runat="server" ID="RadGrid1" OnNeedDataSource="RadGrid1_NeedDataSource" AllowMultiRowSelection="true">
    <ClientSettings>
        <Selecting AllowRowSelect="true" />
        <ClientEvents OnRowDeselecting="rowDeselecting" OnRowClick="rowClick" />
    </ClientSettings>
</telerik:RadGrid>

Hope this helps.
