Update the text of the edited node.

[Andres]

hi, in the code behind I call a Confirm box in javascript(client-side), with a button that says Yes an other that says No. If the user clicks NO, the method CancelNodeEdited() is called. So I pass the old description as the argument. The problem is that if the user edit the node and enter a new description, then the Confirm box is showed. If the user clicks No, the new description is showed and the old description is not taken. How can I fix this problem ?

if ((dtProjects.Rows.Count > 0) && (checkClientAdminRole()))
                                    {
                                        // set old value to cancel action
                                        e.Node.Attributes["OldNodeDescription"] = e.Node.Attributes["NodeDescription"];

                                        // create warning message
                                        sMessage = "Are you sure you want to edit the Taxanomy? The Tax Return Line is used within your Client by:\\n" + sOtherProjectName;
                                        sMessage = sMessage.Replace("\\", "\\\\").Replace("'", "\\'").Replace("\"", "\\\"");

                                        // register script for user confirmation
                                        sScript = @"var resultado = confirm('" + sMessage + "'); if (!resultado) CancelNodeEdited('" + e.Node.Attributes["OldNodeDescription"] + "');";
                                        ClientScript.RegisterStartupScript(typeof(Page), "jsEditNode", sScript, true);
                                       
                                        // set new value
                                        e.Node.Text = e.Node.Attributes["TaxonomyNotation"] + " " + nodeText;

and in the aspx;

function CancelNodeEdited(oldValue) {   
            tree = document.getElementById('<%=trTaxonomy.ClientID%>');           
            var node = tree.FindNodeByAttribute("NodeDescription", oldValue);                       
            nodetext = node.get_attributes().getAttribute("OldNodeDescription");           
            node.get_attributes().setAttribute("NodeDescription", nodetext);
            node.set_text(node.get_attributes().getAttribute("TaxonomyNotation") + " " + nodetext);
            node.get_attributes().setAttribute("OldNodeDescription", null);
    }

Hello Andres,

In the sample code you have provided it seems to me that you are not referencing the client object of the RadTreeView. You are getting reference to the DOM element instead and thus you could not call any client-side methods.

You should replace the tree = document.getElementById('<%=trTaxonomy.ClientID%>'); with tree = $find('<%=trTaxonomy.ClientID%>');
