[Solved] The old node Text returns back after editing

[shootermv]

The scenario :
My customer wants the tree node text to be edited after some button the page clicked. The scenario is as follows:
1 button clicked
2 selected node in tree became editable (displayed inside textbox)
3 after losing focus the changes are saved

My Code :
When i populate the tree nodes i set the

AllowEdit property to false - to prevent node became editable when clicked.
in the button_Click eventhandler i put call to

 

startNodeInEditMode function

 

as in the following code:

public void startNodeInEditMode(string nodeValue)

{

                 

    string js = "Sys.Application.add_load(editNode); function editNode(){ ";

    js += "var tree = $find(\"" + RadTreeView1.ClientID + "\");";

    js += "var node = tree.get_selectedNode();";

    js += "if (node) node.startEdit();";

    js += "Sys.Application.remove_load(editNode);};";

    RadScriptManager.RegisterStartupScript(Page, Page.GetType(), "nodeEdit", js, true);           

}

protected void RadTreeView1_NodeEdit(object sender, RadTreeNodeEditEventArgs e)

{

     e.Node.Text = e.Text;

The Problem :
The changed  text of the node returns back to old version of text (the changes suddenly disappear after few seconds and old text appear)
Althougt i see that changes are saved in db inside the RadTreeView1_NodeEdit function.


Please help

Seems i've solved my own problem...
For some who interested to read my solution:
I noticed that old  node text "comes back" only if after editing the node-text user clicking on the same node (if user clicked somewhere else or lose focus - the changes stays)


After look inside RadTreeView1_NodeClick method i find:
that althought  inside preceding  function RadTreeView1_NodeEdit node text was replaced by new version, in the RadTreeView1_NodeClick ,e.Node.Text  value remains the old version value (why??? may be bug?)

My work around:

 

public void startNodeInEditMode(string nodeValue)
{
    //This code is to prevent old Text value
    //of resently edited node to return back
    //in response of selected node click (telerik bug)
    Session["oldText"] = RadTreeView1.SelectedNode.Text;

    string js = "Sys.Application.add_load(editNode); function editNode(){ ";
    js += "var tree = $find(\"" + RadTreeView1.ClientID + "\");";
    js += "var node = tree.get_selectedNode();";
    js += "if (node) node.startEdit();";
    js += "Sys.Application.remove_load(editNode);};";
    RadScriptManager.RegisterStartupScript(Page, Page.GetType(), "nodeEdit", js, true);
}
protected void RadTreeView1_NodeEdit(object sender, RadTreeNodeEditEventArgs e)
{
    //This code is to prevent old Text value
    //of resently edited node to return back
    //in response of selected node click (telerik bug)
    Session["nodeValue"] = e.Node.Value;
    Session["nodeTextNew"] = e.Text;


    e.Node.Text = e.Text;
    //Save to DB
    }
protected void RadTreeView1_NodeClick(object sender, RadTreeNodeEventArgs e)
{
    //This code is to prevent old Text value
    //of resently edited node to return back
    //in response of selected node click (telerik bug)
    if (Session["oldText"] != null)
    {
        if (Session["oldText"].ToString() == e.Node.Text && e.Node.Value == Session["nodeValue"].ToString())
        {
            e.Node.Text = Session["nodeTextNew"].ToString();
            Session.Remove("nodeTextNew");
            Session.Remove("oldText");
        }
    }

May be it is not the best solution, but it works.
