I try to follow the example in https://demos.telerik.com/aspnet-ajax/orgchart/examples/applicationscenarios/drilldowntoviewdetails/defaultvb.aspx?show-source=true but if I run the code and click on an icon for drill-down I get the error at the line "If e.SourceNode.ID <> "1" Then":

Telerik.Web.UI.OrgChartDrillDownEventArguments.SourceNode.get returned Nothing.

The code is:

  Private Sub RadOrgChart2_DrillDown(sender As Object, e As Telerik.Web.UI.OrgChartDrillDownEventArguments) Handles RadOrgChart2.DrillDown
      If e.SourceNode.ID <> "1" Then
          Dim item = New OrgChartGroupItem()
          e.SourceNode.Renderer.Controls.Remove(e.SourceNode.Nodes.Renderer)
          e.SourceNode.GroupItems.Clear()
          e.SourceNode.Nodes.Clear()
          e.SourceNode.GroupItems.Add(item)
      End If
  End Sub

Please advise!

Thx
Gerhard

The tab toolbar items (Bold (B), italic (I), underlined (U), etc.) act like a Tab list (one can be selected), but when we navigate on it, the screen reader announces the role as a link, which is confusing.

Also, with the role link, the user is not getting enough information about which one is currently selected (visually with colour indication). The screen reader announces as 'Bold, link'.

The recording is attached in the zip file.

As you can see from the image, on mobile devices the date ends up breaking and making it impossible to view it completely.

This is my code:
<div class="col-xl-3 col-sm-6 col-md-6 col-xs-12 mb-2">
    <span class="EstiloLabelSimples">Data Vencimento:</span>
    <telerik:RadDatePicker RenderMode="Lightweight" ID="txtDataVencimentoCadastro" Width="100%" runat="server" />
</div>

I've tried using other RenderMode types, but none of them worked. Could someone help me achieve this responsiveness?

Hello,

I'm loading a RadTreeView from an xml file.  This has been working fine for a long time.

I've been tasked with adding a text link to another page to the right of specific nodes.

Since I'm using LoadContentFile of my RadTreeView, I'm not sure if there is a way to manipulate the nodes to add a link when loading data.

In my example below I need to find a way to add the Section links to the right of my nodes.  Can I add the section text and url as properties of a node in my xml?

Example layout

-Top

-2000s

-2021 Section 1

-2022  Section 1

-2023 Section 2

Thank you

Hi there

In order to get differing steps to show the levels on my stacked chart I can kind of do it using additional Y axis, but obviously this is showing them on separate lines.

Is it possible to manipulate the layout so that the lines are on top of each other so it looks like 1 line?

 

 

Thanks for your help

Hi Team,

We are using the Telerik RadScheduler control in our ASP.NET Web Application, configured with a Timeline view and vertical resource grouping. Appointments are displayed in the content pane, similar to the example provided in the following link, with the key difference being that resource grouping is set to vertical:

We are encountering a UI issue when a user drags an appointment to the first hour in the timeline view. If the appointment is moved slightly beyond the start of the timeline (into the previous period), it visually shrinks in width. Upon triggering the confirmation dialog and selecting "No", the appointment correctly returns to its original position, but its visual width remains reduced. This is corrected only upon a manual page refresh. Images shown below for reference.

Hi,

 

How can we display the input boxes for start- and enddate dates vertically instead of horizontally?
