treeview selected node font style does not change

Posted By:      Posted Date: October 12, 2010    Points: 0   Category :ASP.Net

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" />

Is it possible to change the title bar background and the font style on default template?



Is there any way to change the default top link /title bar picture and the fonts of the title without breaking anything in the layout/structure?

I have changed the theme to Obsedian and I would also like to change the picture of the title bar of this theme and also the font/style of the title, top link bar, menus..etc. Is there a way to do this?

Please note: I am using WSS 3.0 and I am not the Administrator of the sharepoint. I am only the site admin of some sites on this sharepoint. I can do some basic customization using SPD.

Basically, what I am trying to do is that I want to set up a sharepoint site, however I want to make it NOT look like a sharepoint site.Well I know this is possible, but for my case it might be just partially possible due to the limitation that I am not the Site collection admin and hence I do not have direct access to the server itself.

What I want is to hide most of the sharepoint links/menus/bars, etc and use my own buttons/hyperlinks etc .. for user to navigate on the sites.

Thanks in advance for your help/advices.



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

How to handle treeview selected node changed event



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

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?

ASP.NET 4.0 Menu Top Level selected item style


I want to apply a css class to the level 1 menu item (parent) when it or any or it's children are selected.

I've looked at MSDN documentation and any number of examples and walkthroughs but I haven't come up with a way of managing this. I was thinking something like this might work but the style is not being applied to the parent. To further complicate matters, if I try to apply a css style to StaticSelectedStyle it doesn't pick it up at all.

Menu Markup:

<StaticSelectedStyle  Font-Bold="True" ForeColor="#3333CC" />

Code Behind:

        protected void MenuItemClick_NavMenu(Object sender, MenuEventArgs e)


            MenuItem parentItem = e.Item.Parent;

            if (parentItem != null)


                parentItem.Selected = true;



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
