Use attached to reproduce:
1. Click the button
2. Change the tab and go back to the diagram
Workaround:
Add the layout before showing the form
How to reproduce: add a MapCallout to a layer and then try to hit test it in the MouseDown event of the control. The element is not always returned even though it contains the mouse location:
private void RadMap1_MouseDown(object sender, MouseEventArgs e){
PointL point = new PointL(e.X - this.radMap1.MapElement.PanOffset.Width, e.Y - this.radMap1.MapElement.PanOffset.Height);
MapCallout callout2 = this.radMap1.Layers.HitTest(point) as MapCallout;
if (callout2 != null)
{
RadMessageBox.Show("MapCallout!");
}
}
Use attached to reproduce.
Workaround:
public RadForm1(){
InitializeComponent();
radPdfViewer1.ContainerElement.BookmarksTree.SelectedNodeChanged += BookmarksTree_SelectedNodeChanged;
}
private void BookmarksTree_SelectedNodeChanged(object sender, Telerik.WinControls.UI.RadTreeViewEventArgs e)
{
Telerik.Windows.Documents.Fixed.Model.Navigation.BookmarkItem bookmark = e.Node.Tag as Telerik.Windows.Documents.Fixed.Model.Navigation.BookmarkItem;
if (bookmark != null && bookmark.Destination == null)
{
GoToAction goToAction = bookmark.Action as GoToAction;
if (goToAction != null && goToAction.Destination != null)
{
radPdfViewer1.PdfViewerElement.GoToDestination(goToAction.Destination);
}
}
}
Workaround:

{

{
return new MyImageEditorElement();
}

Your website is horrible.
I spent an entire afternoon looking for information about how to add and retrieve data to/from a dropdown list control that should be intuitively available in close proximity to it's "Overview" page (after a lot of stumbling around I found where the "add" part was but the "retrieve" part was not found. I finally gave up and pinged Support. Another day is lost.).
And this isn't the first time I spent several hours searching for fundamental class information such as that which would be locatable in a traversable complete class hierarchy. I couldn't even find signatures to constructors for basic components such as RadProperty.
I hate to say it but your website is approaching the near-uselessness that plagues MSDN.
The difference is that I'm paying a truckload of money for the Telerik library. I dread using new controls for your product because I know what an exercise in rage it's going to be figuring out how it works. You laugh, I know. I understand. But it's the truth. I need to wear a mouth guard or pop some Xanax every time I come here. BTW, can I get a refund?
If not, please rewrite your website with your clientele in mind. Assume they know nothing that you know about your product.
My suggested solution is to use a visual model such as is demonstrated at: https://docs.telerik.com/devtools/winforms/telerik-presentation-framework/class-hierarchy/class-hierarchy-overview.html.
You could even start out with a scrolling 400 square-foot wall chart. I wouldn't care if it took a half-hour to download. I'd still be saving time.
And that's both my feedback and feature request that'll wind up in the digital dumpster.

You can use the following code snippet and follow the steps from the provided gif file:
public RadForm1(){
InitializeComponent();
DataTable dt = new DataTable();
dt.Columns.Add("Id");
for (int i = 0; i < 100; i++)
{
dt.Rows.Add(i);
}
this.radMultiColumnComboBox1.DisplayMember = "Id";
this.radMultiColumnComboBox1.ValueMember = "Id";
this.radMultiColumnComboBox1.DataSource = dt;
this.radMultiColumnComboBox1.SelectedIndex = -1;
this.radMultiColumnComboBox1.SelectedIndexChanged += radMultiColumnComboBox1_SelectedIndexChanged;
}
private void radMultiColumnComboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
RadMessageBox.Show("You just selected index " + this.radMultiColumnComboBox1.SelectedIndex);
}

Hallo,
I was using "Controldefault" theme and I got such an error message on laptops and desctops with smaller resolution when pointing to the gridview control:
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:

</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
At the same time on desctops with full HD everything was OK. I solved my problem selecting "Windows7" theme but I don't think it is a normal situation so I decided to inform You.
I use Visual Studio 2019 but I was unable to choose it from the list to finish the ticket.
Workaround:
radGridView1.CurrentRow = null;
How to reproduce:
this.radDiagram1.RoutingService.Router = new Telerik.Windows.Diagrams.Core.OrgTreeRouter() { TreeLayoutType = Telerik.Windows.Diagrams.Core.TreeLayoutType.TipOverTree };
this.radDiagram1.RouteConnections = true;
The scroll in the SuggestedActionsElement cannot be made visible, one can scroll only with the mouse. Introduce a property so there is an indication that additional items are available.
In addition, the CreateChatElement in RadChat class should be made virtual.
Workaround:
private Size minSizeState;
private Size maxSizeState;
protected override void HandleDpiChanged()
{
//base.HandleDpiChanged();
float scaleFactor = 1f;
if (this.oldDpi != 0)
{
scaleFactor = (float)this.currentDpi / this.oldDpi;
}
else if (this.oldDpi == 0) //Form shown for the first time.
{
scaleFactor = (float)this.currentDpi / 96f;
}
if (scaleFactor == 1f)
{
return;
}
this.maxSizeState = this.MaximumSize;
this.minSizeState = this.MinimumSize;
this.MinimumSize = Size.Empty;
this.MaximumSize = Size.Empty;
this.Scale(new SizeF(scaleFactor, scaleFactor));
this.MinimumSize = TelerikDpiHelper.ScaleSize(this.minSizeState, new SizeF(scaleFactor, scaleFactor));
this.MaximumSize = TelerikDpiHelper.ScaleSize(this.maxSizeState, new SizeF(scaleFactor, scaleFactor));
}
I used RadPageView under the theme "VisualStudio2012LightTheme" .
The ViewMode of RadPageview is Stack.
I wanted to change the font size of page header in runtime but it was not workable.
If I changed the theme to VisualStudio2012DarkTheme or Office2013LightTheme, it worked fine.
