Web Forms :: Clear Out The treeview Nodes Before Adding New Nodes From Different Date?
Feb 18, 2010I have a code that load hierarchy( nodes) into trew view.. by selecting different date, the hierarchy result from SP will show in the treeview..
the problem is even though I select a different date.. the result( node) of previous date is still showing in addition to the new hierarchy result...
it;s like the new result node is appended to existing node.. instead of refreshing the node and showing only the new result. How can I clear out the treeview nodes before adding new nodes from different date?

Jul 15, 2010I'm coding an Webpage in VS.NET 2010[C#] that scans the Serial Number of Product into a Treeview in a Work Order > Box > Product hierarchy.
What I wanted to do was to use the following to Remove the ChildNodes:
//Use the GetEnumerator method to create an enumerator that contains the root node data.
IEnumerator nodeEnumerator = myTreeView.CheckedNodes.GetEnumerator();
// Iterate through the enumerator to display the root nodes.
while (nodeEnumerator.MoveNext())
{
/In here I would like to Remove the TreeNode
//MessageBox(((TreeNode)(nodeEnumerator.Current)).Text);
}
}
else
{
MessageBox("The TreeView control does not have any nodes.");

Web Forms :: Treeview Expand/collapse All Nodes Client Side?
Mar 26, 2010This is so frustrating...that such a simple feature should not be included in the design of this control. I am using the cssfriendly adapters and the rendered code is shown below.
I thought I might be able to use the adapter's treeview JS function ExpandCollapse__AspNetTreeView(this) since this is what is called when I click on the node that causes it to expand/contract. But that did not work.
I have seen other code posted but it seemed to imply the treeview was a table not a ul.
Does anyone know how to simply expand or collapse all nodes from a link button without doing the postback. Of course the postback works but what a waste to have to postback to do such a simple action.
Why doesn' t MS consider the users and developers when creating these controls and tools? Stupid!

Forms Data Controls :: TreeView Doesn't Display All Nodes?
Jan 30, 2011I've created a custom implementation of SiteMapNode. I've attached it to Menu and it works ok. I've attached it to TreeView and it shows only nodes of one level. If I specify at SiteMapDataSource's ShowStartingNode==true, then I will see only root node and no expand buttons, if I specify ShowStartingNode==false, then I will see root's child nodes and no expand buttons also. What's wrong?

Feb 8, 2010I am trying to maintain the state of a TreeView on postback. I have a simple method to save the state of the tree on postback but it does not seem to capture the Expanded and the Selected state. Also, i have another method to restore the tree state after a postback. When a user selects an item in the TreeView i would like to have this item highlighted/selected. Along those lines i would also like to have all expanded or collapsed mainated after a postback.

Forms Data Controls :: Dynamically Added Treeview - Can't Get Checked Nodes Populated On Demand?
Jul 23, 2010the problem is actually in the subject. I have custom control that uses treeview. The control is added dynamically. Nodes for this treeview are populated on demand.

View 2 RepliesCan Treeview Nodes Work Without Javascript
Jan 22, 2011I understand that a treeview cannot expand/collapse without javascript. But is it possible to open the treeview in expanded form when javascript is disabled? Even if I cannot expand/collapse the nodes, at least I can click on the nodes that will display the data related to that node.
Similar to the treeview used in online auction sites, our treeview looks something like this: [URL], where clicking on a link will redirect me, and clicking on the "+" will expand or collapse the node. The only difference would be that ours is databound.
Another developer is working on this and he tells me that this is not possible without javascript. This webform in particular works almost entirely without javascript, and I'd like the treeview to also work partially.

TreeView Nodes Not Expanding And Collapsing?

Treeview Limit For Number Of Nodes
Feb 22, 2012Any limit to the number of nodes you can have in a treeview, I have been having some problems getting it to display with the panel I made. I have actually decided not to use the treeview, in fact may drop this part of the app altogether, but just wondering for future reference. I know if certain browsers have a limit for the the url, but can not seem to find anything, if there is anything, on a node limit. I am using asp.net 3.5 with VB and my browser is IE8, well the only one I tested on.
