Contextmenu in empty grid

[usha]

Hi,

    I have a tree view with folder structure. when i double click on any folder it displays all files and folder in a grid. that grid consisiting of context menu with some options. now my question is how to display context menu on grid when i double click on folder if that folder contains no records and folders(means displaying context menu on empty Rad Grid).

Thanks in adv

Hello Usha,

You could achieve your scenario by setting the RadGrid DataSource property to a empty list of objects which will cause the grid to show its NoRecordsTemplate so the context menu will be accessible. Additionally, you could use the RadContextMenu showAt function and specify the x and y coordinates of the grid.

• RadMenu and RadContextMenu objects

this.RadGrid1.DataSource = new List<object>();

Hello Usha,

I have assembled a sample project demonstrating how the desired functionality could be implemented. The idea is to include the RadGrid in the RadContextMenu Targets collection as it is shown below. Note that binding to a source with no records is required to show the grid.

<telerik:RadContextMenu ID="RadContextMenu1" runat="server">
    <Targets>
        <telerik:ContextMenuControlTarget ControlID="RadGrid2" />
    </Targets>
    <Items>
        <telerik:RadMenuItem Text="Item1" Value="Value1">
        </telerik:RadMenuItem>
        <telerik:RadMenuItem Text="Item2" Value="Value2">
        </telerik:RadMenuItem>
    </Items>
</telerik:RadContextMenu>
<telerik:RadGrid ID="RadGrid2" runat="server" OnNeedDataSource="RadGrid2_NeedDataSource">
    <MasterTableView>
        <NoRecordsTemplate>
            No recods available. Right-click for context menu.
        </NoRecordsTemplate>
    </MasterTableView>
</telerik:RadGrid>
