[Solved] Setting the buttons when used as a RadGrid CommandItem

[Stuart Hemming]

I've a grid in a UserControl. The CommandItem template is defined like this ...

        <CommandItemTemplate>
        <telerik:RadToolBar runat="server" ID="GridCommandItemToolbar" AutoPostBack="false" Skin="WebBlue"
            OnClientButtonClicked="ToolBarButtonClicked" Style="width: 100%" Visible="true">
            <CollapseAnimation Duration="200" Type="OutQuint" />
            <Items>
                <telerik:RadToolBarButton runat="server" Enabled="false" ToolTip="Add Document" Value="AddDocument" ImageUrl="~/Images/Office/document_file/png/16/document_add_16x16.png">
                </telerik:RadToolBarButton>
                <telerik:RadToolBarButton runat="server" Enabled="false" ToolTip="Edit Document" Value="EditDocument" ImageUrl="~/Images/Office/document_file/png/16/document_edit_16x16.png">
                </telerik:RadToolBarButton>
                <telerik:RadToolBarButton runat="server" Enabled="false" ToolTip="Delete Document" Value="DeleteDocument" ImageUrl="~/Images/Office/document_file/png/16/document_delete_16x16.png">
                </telerik:RadToolBarButton>
                <telerik:RadToolBarButton runat="server" IsSeparator="true"></telerik:RadToolBarButton>
                <telerik:RadToolBarButton runat="server" Enabled="false" ToolTip="View Document History" Value="ViewHistory" CheckOnClick="true" Checked="false" AllowSelfUnCheck="true" ImageUrl="~/Images/Office/document_file/png/16/document_properties_16x16.png">
                </telerik:RadToolBarButton>

            </Items>
        </telerik:RadToolBar>
        </CommandItemTemplate>

I need to be able to enble/disable the buttons based on values and events on the calling page.

I thought to do it like this ...

var tb = $find("<%= GridCommandItemToolbar.ClientID %>");

But "GridCommandItemToolbar" isn't recognised, which I suppose is OK. But I can't seem to create a property on the UserControl that lets me get at the ToolBar server-side so I can access its ClientID in the <% %> code block on the page.

Can anyone offer a solution?

Never mind chaps, I've sorted it.

For the curious amongst you, the answer appears to be to:

1. Create a global variable on your calling page,
2. Wire up the OnClientLoad toolbar client-side event,
3. In the event handler access the object in the previously declared gloabl variable.

Clever me! 8-)

Well, I'd sorted it for accessing the ToolBar on the client, but now I need access to the ToolBar server-side.

Hints anyone?

I could get at using...

RadToolBar tb = (RadToolBar)RadGrid1.MasterTableView.Controls[0].Controls[0].Controls[0].Controls[0].Controls[1];

but that can't be the right/best way, can it?

Does anyone want to take a shot at this?

Hi Stuart,

You can try finding the ToolBar server side as shown below:

GridCommandItem commandItem = RadGrid1.MasterTableView.GetItems(GridItemType.CommandItem)[0] as GridCommandItem;
RadToolBar toolBar = commandItem.FindControl("GridCommandItemToolbar") as RadToolBar;

More information on how to access controls in RadGrid is available here.

Iana,

Thanks for that. I would never have found that without reading all of the help file!

Thanks again!
