Classic RadTreeView: No click event with ExpandMode="ServerSideCallBack"

Hello!

I'm still using the classic RadTreeView and can't find out why the click event is not fireing. I'm using ExpandMode="ServerSideCallBack".

 

Here my code:

 

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
 
<%@ Register Assembly="RadTreeView.Net2" Namespace="Telerik.WebControls" TagPrefix="radT" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<head runat="server">
   <title></title>
</head>
<body>
   <form id="form1" runat="server">
   <div>
      <asp:ScriptManager ID="SM" runat="server" />
      <radT:RadTreeView ID="tree" runat="server" OnNodeClick="tree_NodeClick" OnNodeExpand="tree_NodeExpand">
         <Nodes>
            <radT:RadTreeNode runat="server" ExpandMode="ServerSideCallBack" Text="Test" />
         </Nodes>
      </radT:RadTreeView>
   </div>
   </form>
</body>
</html>

 

 

using System;
 
using Telerik.WebControls;
 
public partial class _Default : System.Web.UI.Page {
 
   protected void tree_NodeExpand(object sender, RadTreeNodeEventArgs e) {
      var newNode = new RadTreeNode("New Node");
      e.NodeClicked.Nodes.Add(newNode);
   }
 
   protected void tree_NodeClick(object sender, RadTreeNodeEventArgs e) {
      Console.WriteLine(e.NodeClicked.Text);
   }
}

 

Thanks for helping!

 

Regards,

Tonino.

findItemByText not working if text contains ampersand (&)

Hi,

I have a contextual menu associated with a tabstrip.

Here's the menu handler:

 

function activityContextMenuClicked(sender, args) {
                var itemValue = args.get_item().get_value();
                if (itemValue == 'new') {
                    openActivityDialog('new', '', '', '');
                } else if (itemValue == 'edit') {
                    var tabStrip = $find("<%= tbsActivities.ClientID %>");
                    var tab = tabStrip._findItemByText(args.get_targetElement().innerHTML);
                    var activityIDToUpdate = tab.get_value();
                    var activityName = tab.get_text();
                    var activityDesc = tab.get_attributes().getAttribute("Description");
                    openActivityDialog('edit', activityIDToUpdate, activityName, activityDesc);
                } else if (itemValue == 'delete') {
                    var tabStrip = $find("<%= tbsActivities.ClientID %>");
                    var tab = tabStrip._findItemByText(args.get_targetElement().innerHTML);
                    activityIDToDelete = tab.get_value();
                    radconfirm("Are you really sure you want to delete this activity and all of its child elements?", deleteActivityResponse, 300, 100, null, "Delete Activity", null);
                }
            }

I must mention that the tabstrip is built dynamically, so the text is variable.

The above code works fine unless the text contains an ampersand (I suspect other special characters may cause issues as well).

I tried using findItemByValue(args.get_targetElement().value), but that did not work either.

 

Any suggestions?

Thanks

Jim

Inserted rows fail to save if prior call to ClientEvents OnCommand cancels

While using the RadGrid in Batch Mode, I am trying to do some complex client side validation on save. To do so, I am using the ClientEvents-OnCommand to handle it. What I've discovered is that if I cancel the OnCommand event (args.set_cancel(true)) the save is canceled as expected, but when I go to save again (passing validation), what the OnBatchEditCommand command receives on the server side is an UPDATE, not an Insert, and that UPDATE command's newValues and oldValues are both null.

 We are currently using version 2014.3.1209.40  I'd like to know if this has been fixed in a newer version before I upgrade our solution, as that will require a full regression test.

Here is my test jig that shows the issue.

Saving Changes to Grid without using save button in the editable grid row

I have a asp.net web page with standard Telerik Grids as well as some other Telerik controls such as text box, rich editors etc.  

Now currently in order to save data in the form users have to press save in each editable row in the grid after entering data in the row which is the standard grid behavior.  In order to save other text fields in the form, they have to press a separate Save button.  

Is it possible to have one single save button that can trigger save function in the current row in the grid that is being edited?   This single save button will additionally save all the other data in text fields as well.

Additionally users want to be able to have an auto-save feature so form is saved automatically at certain intervals or upon moving away from the page to another page on the site.
