treeview node selection takes a lot of time

Posted By: Posted Date: October 03, 2010 Points: 0 Category :ASP.Net

Hi All,

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.Please suggest what can be done....

The code is as below :

<asp:UpdatePanel ID="updatePnlListBoxes" runat="server">
<ContentTemplate>
<table align="center">
<tr>
<td>
<asp:UpdateProgress ID="UpdateProgress2" runat="server" AssociatedUpdatePanelID="updatePnlListBoxes">
<ProgressTemplate>
<img id="Img2" src="~/images/ajax-loader.gif" alt="" runat="server" />
</ProgressTemplate>
</asp:UpdateProgress>
</td>
</tr>
<tr>
<td>
<asp:TreeView ID="tvNodes" runat="server" NodeIndent="15" ShowExpandCollapse="true"
ShowLines="True" Width="181px">
<ParentNodeStyle Font-Bold="False" />
<HoverNodeStyle Font-Underline="True&

(Imperfect) Solution to TreeView Postback / Client-Side Node Selection Issue

I've seen this question posted on all corners of the web... "How do I disable "AutoPostBack" on the ASP.NET 2.0 TreeView control?!" Unfortunately, most of the answers either don't work, miss the point (don't work right), or boil down to "You can't do it." I happen to know that this behavior worked perfectly in the IEWebControls TreeView that Microsoft released as an add-on prior to ASP.NET 2.0, however. So I set out to find a solution for the ASP.NET 2.0 TreeView issue.

In a nutshell, the behavior that I and others are looking for is to have a TreeView rendered in a page that allows the user to expand, contract, and select nodes within the TreeView without causing a PostBack to the server. This implies two things: (1) the most recently-selected node should be recorded as the currently-selected node [i.e., at PostBack time, the most-recently selected node is actually represented as the SelectedNode]; and (2) the selected node should exhibit the SelectedNodeStyle as specified in the TreeView declaration.

It appears that the TreeView engineers saw only two possible outcomes from selecting a leaf node in a tree: (1) immediately posting back to the server, or (2) immediately navigating to another web page. They apparently did not consider option (3) just allowing selection in-place on the client, while waiting for a click on so

How can i update treeview root node every time based on the record entries

Hi all, I will have an mdi form and with a treeview which has it's initial property as visible =false. If i select an option from menu a child form will exists i will fill some details and click on save when ever click on save i will make the root node of the treeview to some name as File[batch count:0]. Now if i select another option from menu another form will appear and if i fill it with some details and click on save i would like to change the root node name to File[batch count:1] and a child node should exists with some name

expand one node at a time in treeview

To anyone who know how to accomplish this:

I have a tree view like this:

1.1
1.2

2.1
2.2
....

what I want to accomplish is when user click a parent node (for example node 1) every other parent nodes are collapse except the selected node( node 1), in other word, only one subtree is expanded at a time.

Thank you very much!

WCF Service: takes very long time to start up

Hi, What could be the reasons, why my WCF service takes up to 40 seconds to get started? My service class is set to [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)] I am running a thread inside this class. The WCF service gets initialized and opened within the context of this thread. The Initialization: private void InitializeWCFService() { // initialize servcie base addrresses this.SetupBaseAddresses(); //MetaData behaviour : allow HttpGet ServiceMetadataBehavior metaDataBehavior = new ServiceMetadataBehavior(); metaDataBehavior.HttpGetEnabled = true; // initialize service host instance this.seviceHost = new ServiceHost(this, this.httpBaseAddress, this.tcpBaseAddress); // add service endpoints and behavior. this.seviceHost.AddServiceEndpoint(typeof(IUpdateServer), this.GetServerBinding(BindingType.Tcp), EndpointName); this.seviceHost.AddServiceEndpoint(typeof(IUpdateServer), this.GetServerBinding(BindingType.Http), EndpointName); this.seviceHost.Description.Behaviors.Add(metaDataBehavior); // MEX endpoint this.seviceHost.AddServic

WCF - First call to Callback instance from Server takes considerable time to make it to the client.

Hello. There's a performance problem we are facing that we are unable to fix using DuplexChannels. The first call made by the client to the server reaches the server instantly. The first call made by the server to the first client using a Callback proxy will take several seconds to reach the client. All subsequent calls to the client (as well as other clients) will reach and execute instantly. The client connects to the Server using a proxy to IServiceProvision, supplies an instance to an implementation of IClientCallback and calls IServiceProvision.Start(). The server instantly processes the call and makes an asynchronous call to IClientCallback.DoWork(), which takes several seconds to enter the client's DoWork() implementation. The remainder of the execution then runs smoothly. Also, the server will experience such a slowdown only for the very first call of the first client that connects to it. Is it normal for the Callback interface to take so much time to warmup, only on the first call to the first client? Below is the full source code. Thanks for any information you may provide. Cheers Mike Shared Class Library using System.ServiceModel; namespace Test { [ServiceContract(Namespace = "http://test/IService", CallbackContract = typeof(IClientCallback))] public interface IServiceProvision { [OperationContract] void Start(); [OperationContract] void

SQLDataAdapter/SQLDataReader takes lot of time for executing a query

All, I have a webpage with 6 drop down lists. User can start with selecting any drop down list first, and then proceed in any order. 1. Assume when the 1st dropdown is selected first, rest 5 drop downs (except 1st) are filtered/updated based on the selected value in the 1st dropdown. 2. Assume user selects the 4th dropdown second, rest 5 drop downs (except 4th) will be filtered/updated but the condition would be based on both 1st drop down and 4th drop down. But while filtering the first drop down, only the 4th drop down is used as filter (self-filter will be ignored). The code works fine but I see a very bad performance hit in time when the user selects the fourth dropdown after selecting three drop downs. I tried using both SQLDataAdapter and SQLDataReader but neither used to solve the issue. The code takes a lot of time on one line in either of the code (which is highlighted below). When I run the query in SQLServer Mgmt Studio, the query completes in a few seconds.Using SQLDataReader: SqlConnection conn = new SqlConnection(CONNECTION); SqlCommand ObjCmd = new SqlCommand(query, conn); ObjCmd.CommandTimeout = 600; conn.Open(); SqlDataReader daSelTools = ObjCmd.ExecuteReader(); //This line takes a lot of time ddl.Items.Clear(); // Call Read before accessing data. while (daSelTools.Read()) { ddl.Items.Add(new ListItem(String.Format("{0}",daSelTools[0])));

Treeview - how to change node icon depending on node contents

I have a treeview in an MVVM application: <TreeView ItemsSource="{Binding RootNodes}"> <TreeView.ItemContainerStyle> <Style TargetType="{x:Type TreeViewItem}"> <Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}" /> <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}" /> <Setter Property="FontWeight" Value="Normal" /> <Style.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="FontWeight" Value="Bold" /> </Trigger> </Style.Triggers> </Style> </TreeView.ItemContainerStyle> <TreeView.ItemTemplate> <HierarchicalDataTemplate ItemsSource="{Binding Children}"> <TextBlock Text="{Binding NodeName}" /> </HierarchicalDataTemplate> </TreeView.ItemTemplate> </TreeView> The treeview is bound to an ObservableCollection called RootNodes. Elements in the RootNodes collection expose a member "NodeName" which is the text for the nodes in the treeview at runtime. They also expose a member called "NodeType", effectively an enumeration that indicates what type of icon should be displa

Why does it takes such a long time to load a parameter?

Hi all, I have a parameter which is filled with a set of about 90.000 rows. When running the report, it takes a long time to view the report. While it loads the report the CPU on the client is getting up with 50% and the memory stacks 300 MB. I think that I am doing something wrong as when I run the query directly at the cube, it takes just 9 seconds. Does anybody have coped with this problem? If so, what are the best practices in this? Your help will be greatly appreciated! Daniel
