    PROJECT DESCRIPTION
    Sometimes you may want to enable users to select multiple RadGrid items with the mouse without the need to hold the Ctrl key (by default this is required, similarly to the Windows Explorer behavior). Here is how to do it.

    ASPX

    <asp:Button ID="Button1" runat="server" Text="Deselect all items" 
        OnClientClick="return DeselectItems()" /> 
     
    <br /><br /> 
     
    <telerik:RadGrid 
        ID="RadGrid1" 
        runat="server" 
        AllowMultiRowSelection="true" 
        OnNeedDataSource="RadGrid_NeedDataSource"> 
        <ClientSettings EnableRowHoverStyle="true"> 
            <Selecting AllowRowSelect="true" EnableDragToSelectRows="false" /> 
            <ClientEvents OnRowDeselecting="MyRowDeselecting" /> 
        </ClientSettings> 
    </telerik:RadGrid> 
     


    Javascript

    var buttonDeselectFlag = false; 
     
    function MyRowDeselecting(sender, args) 
    { 
        if (!buttonDeselectFlag) 
        { 
            args.set_cancel(true); 
        } 
    } 
     
    function DeselectItems() 
    { 
        buttonDeselectFlag = true; 
        var grid = $find("<%= RadGrid1.ClientID %>"); 
        grid.get_masterTableView().clearSelectedItems(); 
        buttonDeselectFlag = false; 
         
        return false; 
    }
