Treeview Item focus is lost

[RK]

When the user clicks on a treeview item checkbox, the following method is called. However, the page is refreshed and the treeview focus is lost. How can I stay with the currently selected item? Thx.

 

protected void rTree_NodeCheck(object sender, RadTreeNodeEventArgs e)

 

 

{

 

  hdnCurrentNode.Value = e.Node.Text;

 

  e.Node.ExpandChildNodes();

 

 

 

  if (0 == e.Node.Level)

 

    {

    e.Node.Nodes[i].Checked = e.Node.Checked;

    }

}

I tried this code as well:

 

 

//RadTreeNode rtn = this.rTree.FindNodeByText(hdnCurrentNode.Value, true);

 

 

 

 

 

 

 

 

//rtn.Selected = true;

 

 

 

 

 

 

 

 

 

//rtn.Focus();

 

 

 

 

 

 

 

 

 

//rtn.Visible = true;

 

But didn't help either.

Hi rk,

You can send the text/value of the node as a JavaScript variable (using the RegisterClientScript) and in the handler of ClientLoad event of the RadTreeView to find the node (using tree.findNodeByText/findNodeByValue), get it's text element (node.get_textElement()) and then focus the element ($telerik.$(nodeElement).focus()).
