When I open a solution in Visual Studio, it often goes into a non-responsive state, with the following report:

The product I use is Telerik WinForm and it is in Trial status.

The Korean message below is translated into English as follows.

"This may cause Visual Studio to become unresponsive. Disabling extensions can improve your experience. Frequency: 6 reports from last week."

Hello,  I am developing a RFID RTLS map that uses an API to obtain a floorplan image, zone polygon coordinates and item X/Y location.  I am trying to use the Map control with the LocalMapProvider however the background image is being duplicated when zooming and scrolling.  I understand why this is happening.  Also all of the properties and functions in the map control should work perfectly.  The problem is the background image.  Since I only have a single static image is the Map control the best control to use?  Can I force the map control to not replicate images and force the polygon points XY to start based on the top left of the image?  Mind you the item location will need to be updated in real time so I wasn't sure if using a report viewer would be the ideal solution. 

Thoughts?

Hello community!!!

I want to change the color of "radWaitingBar" dots programmatically.

I tried something like this (I found it into my form designer) but with no luck...

((Telerik.WinControls.UI.WaitingBarSeparatorElement)(this.PatchSwitch_radWaitingBar.GetChildAt(0).GetChildAt(0).GetChildAt(0))).BackColor = System.Drawing.Color.FromArgb(121, 191, 80);

Hi Telerik,

Trying to find trackball behavior, but I actually need to display a horizontal line, that crosses the given ScatterLineSeries  and starts at the corresponding vertical axis. (Attached an example image.)

Hello,

Is it possible to prevent RadTreeView entering edit mode when you click on a selected node?  We would still like nodes to be editable but only when the user presses F2 or when we programmatically enter edit mode.

Thanks,

Hayley

Hello,

I haven't seen this in the demos or documentation (yet?). is it possible to display bars, lines or sparklines in the cells of a pivot grid ? is this supported by a public method or property? can this be programmed? is this difficult or extensive?

thanks in advance

Telerik UI for WinForms controls used to be automatically added to Visual Studio's Toolbox during the installation process when using .NET 2.0 (up to 4.8) Framework in your project. This means that the Toolbox population relies on the Telerik WinForms version available in the Global Assembly Cache.

With the introduction of .NET Core/.NET 5 and the WinForms designer, the Toolbox configuration doesn't rely on the GAC anymore and it is not necessary to have an installation of the Telerik UI for WinForms suite. The Toolbox version depends on the installed NuGet package:
https://docs.telerik.com/devtools/winforms/core/core-toolbox-version

There is a known issue that any UserControls/ custom controls don't show up in the toolbox for a VB  project with .NET6.  Even the RadControls are not loaded in the toolbox. 

This seems to be a known issue introduced in Visual Studio 2022 17.3 only for VB project with .NET6. Microsoft are currently working on the issue and I believe that an update will be introduced with the fix: https://developercommunity.visualstudio.com/t/Custom-and-User-Controls-not-shown-in-To/10118197 

Is it possible to control only the end of task.

I mean if I don't want the user to modify the start but let him modify the end, is it possible ?

For now I'm just able to set to readOnly the entire task and I want to get control when I let the user modify the task (and which part)

Thx

Not sure where I can submit a bug report but to replicate...

Create nodes on a RadNodeTree.

DoDragDrop on the node that is drag through NodeDragStart

When Node is dropped onto Scheduler, create the appointment.

This causes the program to flicker a lot and multiple appointments are created.

    Private Sub MyNodeTree_DragStarted(sender As Object, e As RadTreeViewDragEventArgs) Handles MyNodeTree.DragStarted
        If e.Node.Level = 0 Then
            MyNodeTree.DoDragDrop(e.Node, DragDropEffects.All)
        Else
            Return
        End If
    End Sub

    Private Sub RadScheduler1_DragEnter(sender As Object, e As DragEventArgs) Handles RadScheduler1.DragEnter
        If e.Data.GetDataPresent(GetType(RadTreeNode)) = True Then
            e.Effect = DragDropEffects.All
        End If
    End Sub

    Private Sub RadScheduler1_DragDrop(sender As Object, e As DragEventArgs) Handles RadScheduler1.DragDrop
            Dim node As RadTreeNode = e.Data.GetData(GetType(RadTreeNode))
            Dim point As Point = Me.ScheduleCalendar.PointToClient(New Point(e.X, e.Y))
            Dim schedulerCell As SchedulerCellElement = SchedulerUIHelper.GetCellAtPoint(point, Me.ScheduleCalendar)
            If schedulerCell IsNot Nothing Then
                Dim dragObject As String = e.Data.GetDataPresent(GetType(String))
                If dragObject IsNot Nothing Then
                    ScheduleCalendar.Appointments.BeginUpdate()
                    Dim ap As New Appointment(schedulerCell.Date, TimeSpan.FromMinutes(1), node.Name, "")
                    ap.AllDay = True
                    ap.BackgroundId = node.Index + 1
                    Me.ScheduleCalendar.Appointments.Add(ap)
                    ScheduleCalendar.Appointments.EndUpdate()
                End If
            End If

    End Sub
