[Solved] Getting A RadTreeView in a RadPanelBar

[Seth]

In a previous post I asked this question and I got a working response.  I was able to use...

myThumb = <%= rpbAttibutes.FindItemByValue("TemplateHolder").FindControl("wtvDoc").ClientID %>;

	<telerik:RadPanelbar ID="rpbAttibutes" runat="server" Skin="Vista" ExpandMode="FullExpandedItem" Height="100%" Width="100%">
	<Items>
	<telerik:RadPanelItem runat="server" Text="Thumbnails" Expanded="true">
	<Items>
	<telerik:RadPanelItem Value="TemplateHolder" Height="100%">
	<ItemTemplate>
	<center>
	<cc1:WebThumbnailViewer ID="wtvDoc" runat="server" Width="100%" Height="99%" ViewerID="wivDoc" BackColor="LightGray" BorderColor="#A7BAC5" BorderWidth="0" Centered="true" ScrollBarVisibility="Dynamic" />
	</center>
	</ItemTemplate>
	</telerik:RadPanelItem>
	</Items>
	</telerik:RadPanelItem>

...to get a control from inside a RadPanelBar Item control.

I am calling that script on a page load event and it works fine.  This code, although it gives me an [object], does not give me the actual treeview object.

oTree = <%= rpbCabinets.FindItemByValue("TemplateHolder").FindControl("rtvItems").ClientID %>;

	<telerik:RadPanelBar ID="rpbCabinets" runat="server" Skin="Vista" ExpandMode="FullExpandedItem" Width="100%" Height="100%">
	<Items>
	<telerik:RadPanelItem runat="server" Text="Cabinets" Expanded="True">
	<Items>
	<telerik:RadPanelItem runat="server" Value="TemplateHolder" Height="100%">
	<ItemTemplate>
	<telerik:RadTreeView ID="rtvItems" runat="server" Width="100%" Height="99%" Skin="Office2007" LoadingStatusPosition="BelowNodeText" PersistLoadOnDemandNodes="true"
	OnClientNodeClicked="AfterClientClickHandler"
	OnClientContextMenuShowing="onClientContextMenuShowing"
	OnClientContextMenuItemClicked="onClientContextMenuItemClicked"
	OnNodeExpand="rtvItems_NodeExpand"
	OnNodeClick="rtvItems_NodeClick">
	<CollapseAnimation Duration="100" Type="OutQuint" />
	<ExpandAnimation Duration="200" Type="OutQuint" />
	<ContextMenus>
	<telerik:RadTreeViewContextMenu ID="rtvcmCabinet" Skin="Vista" runat="server" Flow="Horizontal">
	<Items>
	<telerik:RadMenuItem Text="Create Folder" Value="CreateFolder" ExpandMode="ClientSide" runat="server" >
	<GroupSettings ExpandDirection="Auto" Flow="Vertical" />
	</telerik:RadMenuItem>
	<telerik:RadMenuItem Text="Export Items" Value="ExportItems" ExpandMode="ClientSide" runat="server" ImageUrl="images/exportFolder.gif" >
	<GroupSettings ExpandDirection="Auto" Flow="Vertical" />
	</telerik:RadMenuItem>
	<telerik:RadMenuItem Text="Import Item" Value="Import" ExpandMode="ClientSide" runat="server" >
	<GroupSettings ExpandDirection="Auto" Flow="Vertical" />
	</telerik:RadMenuItem>
	<telerik:RadMenuItem Text="Export Item" Value="ExportItem" ExpandMode="ClientSide" runat="server" >
	<GroupSettings ExpandDirection="Auto" Flow="Vertical" />
	</telerik:RadMenuItem>
	</Items>
	<DefaultGroupSettings ExpandDirection="Auto" Flow="Vertical" />
	<CollapseAnimation Duration="200" Type="OutQuint" />
	<ExpandAnimation Type="OutQuart" />
	</telerik:RadTreeViewContextMenu>
	</ContextMenus>
	</telerik:RadTreeView>
	</ItemTemplate>
	</telerik:RadPanelItem>
	</Items>
	</telerik:RadPanelItem>

Do I need to type cast it or something?  How do I do that?

Hi Seth,

You need to convert the object to type of RadTreeView.

You can do it by using the following code:

myThumb = <%= Ctype(rpbAttibutes.FindItemByValue("TemplateHolder").FindControl("wtvDoc"),RadTreeView).ClientID %>;

Hope this helps.

No luck.  Strange, that same code works fine in the vb codebehind.

I assigned a global variable to the TreeView in the OnClientNodeClicked event, I am hoping I don't need access to the treeview before that event is fired.

Thanks anyway.

Hello Seth,

Yes, the code I sent you is for VB. The code for C# will be

myThumb = <%= ((RadTreeView) rpbAttibutes.FindItemByValue("TemplateHolder").FindControl("wtvDoc")).ClientID %>;

I am sorry for the inconvenience.
