Strange behavior (PropertyGridSpinEditor)

if you completely delete the contents in the editor and press the <Enter> key, then int.MinValue is returned.

Why? In this case, you must return either null or 0 or do nothing.

Troube adding custom nodes to treeview

Hi,

I'm able to get the samples to work but I'm having trouble adding to my project. It seems that TreeViewElement_CreateNodeElement isn't firing.

Can anyone see what I might be missing? The code below just needs a radtreeview named tvProjectPath.

Thanks in advance!!

Imports Telerik.WinControls.UI

Public Class RadForm1

Private Sub RadForm1_Load(sender As Object, e As EventArgs) Handles Me.Load

Dim rtvTest As Telerik.WinControls.UI.RadTreeView = tvProjectPath

Dim DFSRootNode As New RadTreeNode("Root0")

Dim ProdDataNode As New RadTreeNode("Child1")

Dim JobsNode As New RadTreeNode("Child2")

Dim ProjectRoot As New RadTreeNode("Child3")

'Dim ProjectFolder As New CustomTreeNodeElement()

tvProjectPath.Nodes.Add(DFSRootNode)

DFSRootNode.Nodes.Add(ProdDataNode)

ProdDataNode.Nodes.Add(JobsNode)

JobsNode.Nodes.Add(ProjectRoot)

'ProjectRoot.TreeViewElement =

End Sub

Private Sub CustomNodes_Load(sender As Object, e As EventArgs) Handles Me.Load

Dim test As String = ""

Me.tvProjectPath.ExpandAll()

End Sub

Private Sub TreeViewElement_CreateNodeElement(sender As Object, e As Telerik.WinControls.UI.CreateTreeNodeElementEventArgs)

e.NodeElement = New CustomTreeNodeElement()

End Sub

End Class

Exception adding any control

I was prompted to download a new version, did so.

Created a new project using option one from the dropdown. Could not add any controls to the default form. I thought it was strange that it said [Download] but tried any ways.

Next I created a new project with option 2, worked fine.

So my question is, how do I use option one marked as [Download] even though I already downloaded it and saw zero errors?

Thanks for your time with this matter.

RadForm with UserControl DPI problem

Hello.
In my program I need to create a UserControl that contains Telerik Controls and place them on forms (using RadForm). Everything looks fine until you change the DPI settings in the system. Image with the result of the work of the form in the attached files. At the top of the screen, it's just on the form, at the bottom I'm using UserControl. Tell me how to fix it. For RadForm and UserControl, I set AutoScaleMode.DPI and also I need to use the font Segoe UI 9.75

I use Telerik 2018.2 with .Net 3.5 Below I gave examples of my code (Forms and controls). I very much rely on your help and advice.

Add XAML into existing richtextboxeditor

Hi,

I have a richtextboxeditor that has imported and loaded an XAML document. I have another XAML document/section I would like to append/merge with the existing one. Using import method only erase prior loaded XAML and not append the new XAML content. Haven't been able to figure out a way to add XAML / append it to the already loaded XAML document. Any help would be appreciated.

How to do grouped columns correctly?

Hello

I'm a newbie to Telerik RadGrid and have been struggling to find the correct code to have a group summary row with columns. I find examples where the summary rows have text on the group header, but no examples where the summary rows can have values in the columns? Is this even possible with the RadGrid. I have used other manufacturer's controls and this is possible, but can't find any example code where this is possible with Telerik.

Could someone please provide some basic sample code to achieve the group summary rows with columns as in the screenshot. A simple test project demonstrated this would be appreciated.

Thanks
