I am trying to change one element in the NodeTemplate of a Treeview and my code is not working. It executes fine but the change doesn't show up on the screen. What am I doing wrong?
Here is the the code:
Here is the defintion
Here is the the code:
protected void RadTreeView1_NodeDataBound (object sender, RadTreeNodeEventArgs e)
{
e.Node.ExpandMode = TreeNodeExpandMode.ServerSide;
if (e.Node.Text == "Retailers")
{
RadTreeNode node = RadTreeView1.Nodes[0];
HyperLink hyperLink = (HyperLink)node.FindControl ("HyperLink2");
hyperLink.Visible = false; // this what is want to do
hyperLink.Text = "<
span
style=\"color: #BBBBBB\">X</
span
>"; // this is test to see that the Hyperlink Text changes
// Neither of the above two lines produce the screen changes I am looking for
}
}
