I need to know a way to disable nodes in a tree view when a particular node is checked (the leafs has check boxes), currently I was able to do it but my problem is I have check the check box, then click on the node in order to get it disabled, this not an user friendly at all. I want it to happen when I check the checkbox in the tree node.

I need to check/select all the nodes in a tree view with minimum complexity. My tree view has 3 levels and many nodes in it. below is my code:
<asp:TreeView ID="TreeView1" runat="server" DataSourceID="XmlDataSource1" ShowCheckBoxes="All" ShowExpandCollapse="true"
<DataBindings>
<asp:TreeNodeBinding DataMember="Category" TextField="Name"
ValueField="Value" />
<asp:TreeNodeBinding DataMember="LeafCategory" TextField="Name"
ValueField="Value" />
<asp:TreeNodeBinding DataMember="ChildCategory" TextField="Name"
ValueField="Value" />
<asp:TreeNodeBinding DataMember="SubCategory" TextField="Name"
ValueField="Value" />
<asp:TreeNodeBinding DataMember="Categories" TextField="Name"
ValueField="Value" />
</DataBindings>

In my website, I have a TreeView that has this structure:
Root
|-Leaf
|-Parent
|--Leaf
|--Leaf
|--Child
|---Leaf
|---Leaf
|--Child
|---Leaf
|---Leaf
Is it possible to make the tree in a "collapsed" state where all the Leaf nodes and ONLY leaf nodes are hidden from view until its parent node is expanded? The ideal solution would be to do this without a postback, but any solution at this time would be helpful. The "collapsed" view would look like this:
Root
|-Parent
|--Child
|--Child
Expanding the Root, Parent or Child nodes should show their Leaf nodes. Collapsing the node should re-hide its leaf nodes, but leave the child nodes visible.
I have been trying to delete nodes from a tree view that is being generated from a database. I have the code written and it works, but only on the root Nodes. It will not delete Parents/Childs/Leaf, it will if I delete the root, but I also want to be able to delete parent nodes and such.
Right now i have this code so far
Dim tn As TreeNode = treeView.SelectedNode
treeView.Nodes.Remove(tn)
I know that I can just use treeView.Nodes.Remove(treeView.SelectedNode) but was doing some error checking to see if I could firgue out what was going on. I am using VB6, I am not so worried about the database deleting at the moment. I would prefer not to use the Clear() method as this will remove all the nodes I only want to remove certain ones and keep the rest.
I am trying to build a tree view and was able to create one.The tree is a multi-level tree(6 child levels). The problem I am facing is that for some node the node text is more than 260 characters and for those nodes the node is not expanding and showing the child nodes. I read in the web that the Max lenght for the node Text is 260 only. I am picking these node text values from database and they can be longer than the 260 mark.

View 4 RepliesI have a treeview in my .aspx: <asp:TreeView ID="tvDocCatAndType" runat="server" /> Not much else going on in the page -- two <asp:LinkButtons> and one <asp:Label>; the page is a child of a master page, so these controls are within a <asp:Content> control. I populate the treeview in code -- just 3 node levels, including the root node. All nodes have checkboxes, and I initialize all node.Checked to true. I have some Javascript to do the usual check/uncheck up and down the tree as parent and child node checkboxes are toggled.
No matter how many checkboxes I clear in the UI, on postback every single node has node.Checked = true regardless of the state of the checkbox in the UI. This is not the first time I've used a treeview, but I've never had this problem before. I created this page by light adaptation of an earlier project that works fine.
I have a added a webform user control in my master page. This user control contains an ASP.NET tree view control. How can I get its node click event in my default.aspx which in implemented master page. I have to show some text on default.aspx page against that selected node ID.
