MultiRowSelection - change behaviour

[Martin Gleiß]

Hi,
out of the Box RadGrid with enabled MutlirowSelection behaves similar to Excel. (f.e. mutltiple row selection by holding shift to get all rows from one selected to new selected row or holding pressed ctrl to select various rows).
Logically my grid looses all other selected rows when clicked  on a new row without holding ctr pressed.
Our wants the grid to behave the following way:

• Select row by simple click on ANY place in the row not hollding ctrl without deselecting previously selected rows
• Deselect selected row the same way and behaviour 

Is there a way to make selection behave like having permanently ctrl pressed?


Greetz,
Steffen

Hello,

Try the following code.
aspx:

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" >
 <ClientSettings EnableRowHoverStyle="true">
  <Selecting AllowRowSelect="true" EnableDragToSelectRows="false" />
  <ClientEvents OnRowClick="RadGrid1_OnRowClick" OnRowDeselecting="RadGrid1_OnRowDeselecting" OnRowSelecting="RadGrid1_OnRowSelecting" OnRowSelected=" RadGrid1_OnRowSelected"  />
 </ClientSettings>
</telerik:RadGrid>

Javascript:

<script type="text/javascript">

    var originalClickedRowState = null;
    var clickedRow = null;

    function RadGrid1_OnRowClick(sender, args)
    {
        clickedRow = args.get_gridDataItem();
        originalClickedRowState = args.get_gridDataItem().get_selected();
    }

    function RadGrid1_OnRowDeselecting(sender, args)
    {
        if (clickedRow != null && clickedRow != args.get_gridDataItem())
        {
            args.set_cancel(true);
        }
    }

    function RadGrid1_OnRowSelecting(sender, args)
    {
        if (clickedRow == args.get_gridDataItem() && originalClickedRowState)
        {
            args.set_cancel(true);
            originalClickedRowState = null;
            clickedRow = null;
        }
    }

    function RadGrid1_OnRowSelected(sender, args)
    {
        originalClickedRowState = null;
        clickedRow = null;
    }

</script>
