.net - Calling A Method When A Tree Node Is Clicked In The Standard ASP.NET 2.0 TreeView?

Apr 17, 2009

I have a treeview which i populate dynamically using an XML Datasource. The leaf nodes in the TreeView attempt to open a URL in an iframe within the page.This all works fine, but i would like the iframe to be hidden until the point the leaf node is selected.what event is triggered when the nodes are clicked?? I tried the SelectedNodeChanged event but this doesnt seem to get triggered!

UPDATE - The TreeView code is shown Below

<asp:TreeView ID="TreeView1" runat="server" OnSelectedNodeChanged="TreeView1_SelectedNodeChanged" DataSourceID="XmlDataSource2" AutoGenerateDataBindings="False">
<DataBindings>

[code]....

While fiddling with my code i noticed that when i remove the NavigateUrlField="URL" from my code the tree triggers the SelectedNodeChange event, But does not Trigger if NavigateUrlField="URL" is put back in.

Return A Collection Of Child Nodes From A Treeview Node?

Jul 17, 2010

way to return a collection of treenodes which are children of a selected node? I can't find on MSDN a object of treenodes that is a collection of childnodes.

I have two treeviews, and I am writing code that will copy treenodes from one treeview to another treeview if it is selected. If a parent node is selected, I would also like to copy over all the children. If it is just a childnode, then I would like to copy just that.

Here is what I have so far.

Dim treeobj As TreeNode
treeobj = TreeView2.Nodes.Add(TreeView1.SelectedNode.Text)
If TreeView1.SelectedNode.Parent.Index.ToString Is System.DBNull.Value Then

Check Child And Subchild If Parent Node Is Checked In Treeview?

Apr 25, 2011

I have a treeview with nodes being represented as checkbox.

All works fine i.e when a parent nod is checked, its child and sub child should be checked as well but it won't check only the first subchilds and i am not able to find the solution, i have debugged it many time, but still not able to figure the solution.

I tried finding the solution on the web, but didn't got the proper solution. Below is the code which i am using in my form.

Private Sub trvModule_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles trvModule.AfterCheck, trvReports.AfterCheck, trvMasterAccess.AfterCheck

Treeview - Check All Child Nodes On Checking Parent Node?

Jul 6, 2011

I was wondering how I would go about placing a check in the checkboxes for each child node of a parent node in a TreeView control, if I was to check the parent node.

For example:
Parent 1Child 1
Child 2
Child 3

If I was to check "Parent 1" how would I be able to make that event place a checkbox beside all of the child nodes of "Parent 1"? (Child1, 2, and 3.)
