Hello Giri,

You can try setting the forecolor and font of the node as shown in the code snippet below:
aspx:

<telerik:RadTreeView ID="RadTreeView1" Skin="Inox" runat="server" OnNodeDataBound="RadTreeView1_NodeDataBound" OnPreRender="RadTreeView1_PreRender">
 <Nodes>
   <telerik:RadTreeNode Text="Node1">
     <Nodes>
       <telerik:RadTreeNode Text="SubNode11"></telerik:RadTreeNode>
       <telerik:RadTreeNode Text="SubNode12"></telerik:RadTreeNode>
       <telerik:RadTreeNode Text="SubNode13"></telerik:RadTreeNode>
     </Nodes>
   </telerik:RadTreeNode>
   <telerik:RadTreeNode Text="Node2">
     <Nodes>
       <telerik:RadTreeNode Text="SubNode21"></telerik:RadTreeNode>
       <telerik:RadTreeNode Text="SubNode22"></telerik:RadTreeNode>
       <telerik:RadTreeNode Text="SubNode23"></telerik:RadTreeNode>
     </Nodes>
   </telerik:RadTreeNode>
 </Nodes>
</telerik:RadTreeView>

cs:

 protected void RadTreeView1_PreRender(object sender, EventArgs e)
    {
        foreach (RadTreeNode node in RadTreeView1.Nodes)
        {
            if (node.Text == "Node1")
            {
                node.ForeColor = System.Drawing.Color.Red;
                node.Font.Bold = true;
            }
        }
    }

Thanks
Princy.

I've also tried to do this, but I get an error saying that node.Font.Bold and node.Font.Italic is readonly?

I've also tried the following:

Font

 

myfont = new Font(node.Font, FontStyle.Italic);

 

node.Font = myfont;

Then I get an exception saying that node.Font = null

What am I missing?

Hello Jill-Connie Lorentsen,

Here is the code I used which worked just fine:

<telerik:RadTreeView ID="RadTreeView1" runat="server" Skin="Vista">
    <Nodes>
        <telerik:RadTreeNode runat="server" Text="Root RadTreeNode1">
            <Nodes>
                <telerik:RadTreeNode runat="server" Text="Child RadTreeNode 1">
                </telerik:RadTreeNode>
                <telerik:RadTreeNode runat="server" Text="Child RadTreeNode 2">
                </telerik:RadTreeNode>
            </Nodes>
        </telerik:RadTreeNode>
        <telerik:RadTreeNode runat="server" Text="Root RadTreeNode2">
            <Nodes>
                <telerik:RadTreeNode runat="server" Text="Child RadTreeNode 1">
                </telerik:RadTreeNode>
                <telerik:RadTreeNode runat="server" Text="Child RadTreeNode 2">
                </telerik:RadTreeNode>
            </Nodes>
        </telerik:RadTreeNode>
        <telerik:RadTreeNode runat="server" Text="Root RadTreeNode3">
            <Nodes>
                <telerik:RadTreeNode runat="server" Text="Child RadTreeNode 1">
                </telerik:RadTreeNode>
            </Nodes>
        </telerik:RadTreeNode>
    </Nodes>
</telerik:RadTreeView>

protected void Page_Load(object sender, EventArgs e)
{
    foreach (RadTreeNode node in RadTreeView1.Nodes)
    {
        node.Font.Bold = true;
        node.Font.Italic = true;
    }
}

This made the text of all my root nodes to be Bold and Italic.

What is different in your case?

Nothing is different, - and I still get the message that the property is invalid.

I've worked around the problem, and I now use the font of the tree view as a starting point, and it works fine.

 

 

Font myfont = new Font(radTreeView.Font, FontStyle.Italic);

 

node.Font = myfont;

[Trevor]

Can I set the font size color and more importantly Bold when using an xml file.
I am able to set the following:

Text

ImageUrl

Expanded
NavigateUrl
But I am unable to set the font.

ie.

 

 

 

<Contracts Text="Contract #102" ImageUrl="~/TreeView/drafts.gif" Expanded="True"/ NavigateUrl="home.aspx"/>

 

 

 

 

<Contracts Text="Contract #103" ImageUrl="~/TreeView/drafts.gif" Expanded="True"/>

 

 

 

 

Please advise.
