I have a RadTreeView Bound to the generic List<Category>. Nodes are loaded on Demad.
I have the code :
void Page_Load(object sender, EventArgs e)
void RadTreeView_NodeExpand(object sender, RadTreeNodeEventArgs e)
so when I delete Category from the RadTreeView (the delete button is nested in the NodeTemplate), fisrt I call method to delete the category from the database : (CategoriesData.Delete(SelectedNode.Value)) and after that remove the node from the RadTreeView.
But when I press the refresh Button of the Browser after the node was removed from the TreeView, it appears again.So my question is how I can Refresh the TreeView on delete operation, when i use Load-on demand feature and NodeTemplate.
Best Regards Deyana
