How to handle treeview selected node changed event

Posted By:      Posted Date: September 27, 2010    Points: 0   Category :ASP.Net


From my below sample code, I don't want to use Sessions to handle each click event inside treeview selected node changed.

Secondly, if you suggest me to use treenode.SelectedValue then I would say my values are dyanmically generated.

Everytime a node a clicked, the selected node value is sent in the next request xml to get response and xml schema is different for each click. How do I handle this each click event other than using session variables. I thought of using Request.Item (and integrating with URL redirect property) but I don't want to use that.


Dim trNode As New TreeNode
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then        
            trNode.Text = "Not Postback"
            Session("Flag") = 1
        End If
    End Sub

Protected Sub TreeView1_SelectedNodeChanged(ByVal sender As Object, ByVal e As EventArgs) Handles TreeView1.SelectedNodeChanged
        If Session.Item("Flag") = 1 Then
            trNode.Text = "Is PostBack"
            Session("Flag") = 2
        End If

treeview selected node font style does not change


Hi All,

I have a treeview and I am giving the node style in code behind.

Treeview design is as below:

<asp:TreeView ID="tvIARHierarchies" runat="server" NodeIndent="15" ShowExpandCollapse="true"
                                        ShowLines="True" Width="98%" OnSelectedNodeChanged="tvIARHierarchies_SelectedNodeChanged">
                                        <ParentNodeStyle Font-Bold="False" />
                                        <HoverNodeStyle Font-Underline="True" ForeColor="#6666AA" />

Determine node type selected in TreeView and reading property values


I am hoping that someone can help me get past some problems I am having when using the WPF TreeView control.  I have a TreeView that at most can have 3 levels.  The levels are defined as Project, Discipline, Person which would look like the following:

+ Project

    + Discipline

        - Person

My TreeView is bound to a database using two HierarchicalDataTemplate's and then one DataTemplate (the binding is done in the XAML).

What I would like to get is the following information when selecting an item:

  1. Read the selected value (text of the selected node)
  2. WPF Selected xml node from treeview, I want to populate a datagrid with that node and all child node

    I have populated a tree view from a xml.  I know want to take the node and all children that has been selected by double clicking on the tree node and populate a data grid.

TreeView Set Selected Node

You cannot vote on your own post

I am using Visual Studio 2008 Standard Edition, Visual C++, Windows Forms Application.

I would like to set a treeview node to be "Selected" without clicking on it.

I know that you can click on a Node and that Node then becomes the "Selected" Node but how do you force a Node to be "Selected" (with code) without clicking on it?


Treeview: Select all children if Parent is selected etc...



I'm using a Treeview with  ShowCheckBoxes="All" , so basically I have a tree with all CheckBox Nodes. I'm using the TreeView inside an update panel, and populate the Tree code behind dynamically.

My requrements are the following:

1) Select all the children if parent is selected,

2) When parent is selected, and if we de-select a child, set parent unselected

3) Track if new nodes were selected and previously selected nodes were de-selected (becasue I need to update the database according to the selections in the Tree)

For above 1, I do the following:

protected void TreeView1_TreeNodeCheckChanged(object sender, TreeNodeEventArgs e)
        foreach (TreeNode node in TreeView1.Nodes)
            TreeNodeCollection col = node.ChildNodes;
            //select all children when the parent is checked
            if (col != null && node.Checked)

(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

Infopath Changed Event code triggering in preview but not in web filler.

Hi there, I've written some code for a changed event hookup on a field in infopath 2010. The form is for submission to a sharepoint 2010 forms library. What the code does is fill in a specific value into a field depending on the selected value from a combo-box elsewhere on the form. When i preview this in Infopath 2010 it works perfectly but when i fill out the form through the web interface it simply does nothing. I've got another piece of code which executes on load and this works perfectly in both the preview and the web filler. What it does is just set the value of a field when the form loads. Here is the code, could someone tell me what i'm doing wrong? public void InternalStartup() { EventManager.XmlEvents["/my:myFields/my:service_level"].Changed += new XmlChangedEventHandler(service_level_Changed); EventManager.FormEvents.Loading += new LoadingEventHandler(FormEvents_Loading); } public void service_level_Changed(object sender, XmlEventArgs e) { // Write your code here to change the main data source. XPathNavigator xroot = MainDataSource.CreateNavigator(); XPathNavigator serviceLevel = xroot.SelectSingleNode("/my:myFields/my:service_level",NamespaceManager); XPathNavigator xest = xroot.SelectSingleNode("/my:myFields/my:est_cost", NamespaceManager); switch (serviceLevel.Value)

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
