Please note that issue firstly occurs in version 2018.3.116.
How to reproduce:
1. Add a new RadTabbedForm to a VS2017 VB.NET project.2. Select the new form in the design view window
3. In the properties box, got to "Tabs" and click the ellipsis (…)
4. The collection editor opens.
5. Click the first tab in the list and change the "Text" property to something new
6. Click "OK" to save changes
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:
class MyImageEditor : RadImageEditor
{
protected override RadImageEditorElement CreateImageEditorElement()
{
return new MyImageEditorElement();
}
}
class MyImageEditorElement : RadImageEditorElement
{
protected override ImageEditorCanvasElement CreateCanvasElement()
{
return new MyCanvasElement(this);
}
}
class MyCanvasElement : ImageEditorCanvasElement
{
public MyCanvasElement(RadImageEditorElement owner) : base(owner)
{
}
protected override void PaintElement(IGraphics graphics, float angle, SizeF scale)
{
base.PaintElement(graphics, angle, scale);
if (this.IsCropping)
{
Rectangle dynamicCropRect = GetCropRectangle();
SizeF scaleDown = new SizeF(1f / this.DpiScaleFactor.Width, 1f / this.DpiScaleFactor.Height);
this.AcceptButton.PositionOffset = TelerikDpiHelper.ScaleSizeF(new SizeF((dynamicCropRect.X + dynamicCropRect.Width / 2f) - this.AcceptButton.Location.X - this.AcceptButton.DesiredSize.Width,
dynamicCropRect.Y + dynamicCropRect.Height - (this.AcceptButton.DesiredSize.Height + 10)), scaleDown);
this.CancelButton.PositionOffset = TelerikDpiHelper.ScaleSizeF(new SizeF((dynamicCropRect.X + dynamicCropRect.Width / 2f) - this.CancelButton.Location.X - this.CancelButton.DesiredSize.Width,
(dynamicCropRect.Y + dynamicCropRect.Height - (this.CancelButton.DesiredSize.Height + 10)) - this.CancelButton.Location.Y), scaleDown);
}
}
}
To reproduce:
radMaskedEditBox1.MaskedEditBoxElement.ContextMenuEnabled = true;
Workaround:
public RadForm1(){
InitializeComponent();
radMaskedEditBox1.MaskType = Telerik.WinControls.UI.MaskType.Standard;
radMaskedEditBox1.Mask = "9999999999";
radMaskedEditBox1.MaskedEditBoxElement.ContextMenuEnabled = true;

if (contextMenu.Items.Count == 0)
{
RadMenuItem menuItem = new Telerik.WinControls.UI.RadMenuItem("Cut");

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);
}
LineSeries lineSeries = new LineSeries();
lineSeries.DataPoints.Add(new CategoricalDataPoint(6, DateTime.Now));
lineSeries.DataPoints.Add(new CategoricalDataPoint(4, DateTime.Now.AddDays(1)));
lineSeries.DataPoints.Add(new CategoricalDataPoint(7, DateTime.Now.AddDays(2)));
lineSeries.DataPoints.Add(new CategoricalDataPoint(5, DateTime.Now.AddDays(3)));

lineSeries.HorizontalAxis = continuousAxis;
this.radChartView1.Series.Add(lineSeries);
DateTimeContinuousAxis horizontalAxis = radChartView1.Axes.Get<DateTimeContinuousAxis>(0);
AxisScaleBreak scaleBreakItem = new AxisScaleBreak();scaleBreakItem.Name = "Item1";
