How to hide/ visible fales RadtreeView root node ?

[Nahid]

Hello,

I am developing a web application with telerik rad control. I Use the RadTreeView in my application. The all nodes are generate   from (server side) DB. This demo: http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/contextmenu/defaultcs.aspx

I need to hide/visible false the root node of the tree.  How can I do this?

Thanks and Regards
Nahid

Hello Nahid,

If you're getting your results from the database, just exclude the root node from the query. So excluding records where the ParentID is not null. That way it will not show up in the RadTreeView.

I hope that helps.

Hello,

I have the same problem, I tried your suggestion, but the result is that all rdatreeview items are not visible any more (Not just the root node).

My code:

<asp:SqlDataSource ID="GuideSqlDataSource" runat="server"
                    ConnectionString="<%$ ConnectionStrings:GuidesConnectionString %>"
                    SelectCommand="SELECT [SerID], ([Type] + '~/Guides/Pages/' + [Path] + '.aspx') as TypeAndFullPath, [ParentID], [Title], [Type] FROM [QAGuide] where ParentID <> NULL  order by [Type],[Title]"></asp:SqlDataSource>
                <telerik:RadTreeView ID="GuideRadTreeView" runat="server" OnNodeDataBound="QAGuideRadTreeView_NodeDataBound" OnNodeClick="QAGuideRadTreeView_NodeClick" DataValueField="TypeAndFullPath"
                    DataSourceID="GuideSqlDataSource" DataFieldParentID="ParentID" DataFieldID="SerID" DataTextField="Title"  >
                    <DataBindings>
                        <telerik:RadTreeNodeBinding Depth="0" Expanded="true" />
                    </DataBindings>
                </telerik:RadTreeView>

Please, I need your help in order to hide only the root node.
It is very appreciated to send me the modified code.

Hi Bader,

The query string seems right, could you check what is the returned result from the data source?

Hi friends,


I am sure there is no way to hide the root node in telerik RadtreeView or RadtreeList since all the reply seems diverting from the question asked over here to telerik team.
and you are right my friend, if we exclude root node in the query (fetching nodes from database) then nothing will be bind(nothing will be show in the tree).

So, My advice is not to go for more research for this question.


Thanks
