[Solved] TreeView Custom Attributes

[Zhengmao]

I loaded the treeview from SQL on code behind and add custom attributes there, 

<

telerik:RadTreeView ID="RadTreeView1" runat="server" OnNodeClick="RadTreeView1_NodeClick"

 

Skin="Default" Width="99%" Height="550px" OnClientContextMenuItemClicking="ContextMenuClick"

 

AllowNodeEditing="True" OnNodeEdit="RadTreeView1_NodeEdit" AccessKey="T" EnableDragAndDrop="True"

 

OnNodeDrop="RadTreeView1_NodeDrop" OnNodeExpand="RadTreeView1_NodeExpand" OnContextMenuItemClick="RadTreeView1_ContextMenuItemClick">

 

<ContextMenus>

 

<telerik:RadTreeViewContextMenu ID="treContextMenu" Skin="Vista" runat="server" CollapseAnimation-Duration="100">

 

<Items>

 

<telerik:RadMenuItem Text="Remote Desktop to Server" ImageUrl="Img/new.gif" ></telerik:RadMenuItem>

 

<telerik:RadMenuItem IsSeparator=true></telerik:RadMenuItem>

 

<telerik:RadMenuItem Text="New Node" ImageUrl="Img/new.gif" />

 

<telerik:RadMenuItem Text="Delete Node" ImageUrl="Img/delete.gif" />

 

<telerik:RadMenuItem Text="Rename Node" ImageUrl="Img/rename.gif" PostBack="false" />

 

<telerik:RadMenuItem Text="Copy Node" ImageUrl="Img/copy.gif" />

 

<telerik:RadMenuItem Text="Paste Node" ImageUrl="Img/paste.gif" />

 

</Items>

 

</telerik:RadTreeViewContextMenu>

 

</ContextMenus>

 

<NodeTemplate>

 

<asp:Image ID="imgSeverity" runat="server" ImageUrl="~/Images/greenfla.bmp" />

 

<asp:Image ID="ImgNode" runat="server" ImageUrl="~/Images/city.bmp" />

 

<asp:Label ID="lblNodeName" runat="server"></asp:Label>

 

<%

# DataBinder.Eval(Container.DataItem, "NodeName")%>

</NodeTemplate>

 

</telerik:RadTreeView>

serverNode.Attributes[

"Current_Severity"] = serverRow["Current_Severity"].ToString();

serverNode.Attributes[

"IP_Address"] = serverRow["IP_Address"].ToString();

when I tried to retrieve attrbitue from context menu client function, 

function ContextMenuClick(sender, eventArgs)

{

var node = eventArgs.get_node() ;

alert(node.get_text()) ;

var ip_Address = node.get_attributes().getAttribute("IP_Address");

var NodeType = node.get_attributes().getAttribute("NoteType");

if (eventArgs.get_menuItem().get_text() == "Remote Desktop to Server")

{

runApp(ip_Address) ;

}

}


it told me that ip_address is undefined.

any Idea about it?

Hi Zhengmao,

How do you populate the custom attributes on the server-side? Could you paste here your code? I suspect for some reason the custom attributes are not set for the nodes. You can try inspecting your code with a debugger to see if the code is populating those attributes.
