    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.


    void rTree_NodeCheck(object sender, RadTreeNodeEventArgs e)





      hdnCurrentNode.Value = e.Node.Text;






      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.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()).
