Question

Hi there. I'm using v.s 2008 with c#.

I have a treeview on a master page. And i want to change a node's text. if current user's id isn't equels 222.

if (kul.M_Kullanici_id != 222)
   {
       tvMaind.Nodes[0].ChildNodes[0].ChildNodes[0].Text = "çağın";
   }

My treeview is a sitemap. And t.v has xmldatasource. i wanna rename a node's text when user which has 222 id. I m looking current user in masterpage onunload event. and i m changing text. i can see that change on watch. but in cant see change on the page. I thing xmlsource reload after i change node's text.

Answer 1

Do you want to delete a node? However your code is to update a node text.

Answer 2

You just retrieve required TreeNode and set its Text property.

> tvMenu.Nodes[I].Text = ""; // I: index of node to be retrieved.
