AJAX :: Treeview Node Selection Takes A Lot Of Time?
Oct 1, 2010
I have a tree-view which doesn't have any events and AutoPostBack property is also false. But whenever the treeview node is selected,its taking a lot of time...The tree view is placed inside update panel...I have an update progress and selection of any node shows the progress for atleast 5-6 seconds.
The code is as below :
<asp:UpdatePanel ID="updatePnlListBoxes" runat="server">
<ContentTemplate>
<table align="center">
<tr>
[Code]....
The script manager is in Master page.

I am binding the XML Data to treeview using XMLDataSource. Its working fime, but when the Number of nodes and childnodes increases, the treenode expand and to display the content in iframe takes moer time.
<asp:TreeView ID="TreeView1" OnSelectedNodeChanged = "OnClick" runat="server"
ExpandDepth="0" ShowExpandCollapse="true" ForeColor="Red" Font-Underline = "false"
ondatabinding="TreeView1_DataBinding" CollapseImageUrl = "Resources/TocColapse.bmp" ExpandImageUrl = "Resources/TocParent.bmp" Font-Names="Arial" >
<SelectedNodeStyle Font-Underline="false" BackColor="White" ForeColor="#0483e0" />
<NodeStyle Font-Size="11pt" ForeColor="white" HorizontalPadding="5px"
NodeSpacing="0px" VerticalPadding="0px" Font-Underline = "false" />
<ParentNodeStyle ForeColor="#0483e0" Font-Underline = "false" />
<LeafNodeStyle ForeColor="#0483e0" Font-Underline = "false" ImageUrl = "Resources/TocChild.bmp" />
</asp:TreeView>
<asp:XmlDataSource ID="XmlDataSource1" runat="server" XPath="/*/*" EnableCaching = "false" ></asp:XmlDataSource>
In OnDataBinding event of treeview I implemented the following code:
TreeNodeBinding[] TreeNode = new TreeNodeBinding[Count];
for (int i = 0; i < Count; i++)
{
TreeNode[i] = new TreeNodeBinding();
TreeNode[i].DataMember = TableOfContents[i].GetElementName();
TreeNode[i].TextField = TableOfContents[i].GetFirstAttributeName();
TreeNode[i].ValueField = TableOfContents[i].GetSecondAttributeName();
// TreeNode[i].Target = "contentFrame";
TreeView1.DataBindings.Add(TreeNode[i]);
}

I have a treeview which will be generated dynamically which need to be displayed on left side and when user clicks on a node it need to open a page on the right side of the same page. and each node has different aspx page. so whenever user selects a node the page details should be displayed on the right side .we can use an iframe on the page which will display the different pages clicked on the node.Is there any alternative i can use to display different pages based on the user selection on the right side without using iframe.

I am working on a ASP.NET 2.0 application. It is hosted on IIS 6 on Windows 2003 server.
Few pages have jpeg images (around 50 images and 50 KB each). It takes long time to load the page for the first time. But when i open the same page for the second or third time it is faster.
why does a web page take long time to load for the first time?
Is it cached somewhere when it loads for the first time? Do we have any control over it?

What I am acheiving is a simple treeview which will have a tree structure
dir1
-- xx
dir2
Simple stuff !. Here is the code
TreeNode tree1 = new TreeNode("dir1", "", "", "dir1", "");
tree.Nodes.Add(tree1);
TreeNode node = new TreeNode("xx", "xx");
tree1.ChildNodes.Add(node);
TreeNode tree2 = new TreeNode("dir2", "", "", "dir2", "");
tree.Nodes.Add(tree2);
Now I want to do is collapse all the tree and find a particular node e.g dir1xx
I have put the code
tree.CollapseAll();
tree.FindNode("dir1").Select(); <-- falls over
tree.FindNode("dir1").Expand();
tree.FindNode("dir1/xx").Select();
tree.FindNode("dir1/xx").Expand();
but it falls over on the 2nd line with object not set

I am using a treeview control. I am buliding the tree dynamically. sometimes the tree becomes larger and the down scroll bar is need to see the entire tree. user can select a node from the tree. if one node is selected ,i change the color of the node from server side.
my problem is that if a user selected a node which is bottom in the tree(means, the user used the down scrollbar to see that node), after postback it shows the top of the tree.to see the selected node the user need to use the down scroll bar.
I need to show the selected node after postback. How can I do this?
I am using c# and asp.net

I need to retrieve a specific node from the TreeView in order to dynamically set it's NavigateUrl property. I've tried using the code below:
TreeNode homeLink = TreeView1.FindNode("Home");
However this returns System.NullReferenceException error.My guess is that I'm using a wrong valuePath in the FindNode("Home"); function. I assume that valuePath refers to the "title" property of the node in the SiteMap?ere is an extract from the sitemap:
<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode url="" title="" description="" SelectAction="Expand" roles="*">

I created a sitemap with a treeview navigation in my aspx site. I am hoping someone can show me the code to put in a Masterpage so that when I expand a child node, all other nodes collapse, and when I expand another node, the previous expanded node collapses.
I have an example here of what I am trying to accomplish:
