Hi
I'm getting error in the VS2022 designer when I click on a RadComboBox.
It shows a busy cursor and then a dialog with the message "XAML designer is busy"
When I cancel the dialog it shows a message that an unhandled exception has occurred with the option to reload the designer.
The only way to make the RadComboBox clickable is to switch on "only display platform controls"
Then it shows a generic looking control in the place of the RadComboBox
This is happening on version 2022.3.1109 but was also happening on 2022.2.621
Is this something you can fix? or is the problem something that you have to wait on Microsoft for
Thanks

I am using RadTabItem s. One of them has a RadGridView. EnableRowVirtualization on the grid is set to true as it is by default.
When you change to another tab then change back to the tab with this grid, it is very slow. I am testing with about 2,000 rows. I set EnableRowVirtualization to false and loading and clearing the grid is a little slower, but it's quicker to switch back into the tab with the grid.
It seems to me that switching in and out of this tab when row virtualization is enabled, the grid is disposing and reloading the rows. Loading and clearing the grid with virtualization enabled is faster, but changing tabs is significantly slower than when it's disabled.
I have looked through all the attributes of RadGridView and tried setting a few of them with no luck.
I am trying to figure out if there is some setting/attribute for the RadGridView or RadTabItem I can configure to have tabbing as quick and it is when row virtualization is disabled.

When inserting image to Richtextbox editor (UI for wpf demo application) through insert image command from Ribbon menu and save document as .rtf. Generated document size is more than (almost twice) of inserted image.
To reproduce this issue, insert any image (sample attached) and save as .rtf. When comparing document size with image size.
Image size is 2.94 MB
.rtf document size is 5.89 MB.
When I open image editor to resize image, I noticed that current image size is 51.5 MB (screenshot attached). Is this correct image size?
Another issue I found in Richtextbox editor is that pasting image from clipboard is not working. Same can be reproduced in demo app.
Is there work around to reduce the image size when inserting image from clipboard or inserting image. Also how I can enable paste image from clipboard.
Current behavior generates large .rtf document, which If import to wpf richtextbox editor or MS word then application hangs.

When I create a MapPolygon and then I call SetView with the GeoBounds I get the correct zoom and center.
var polygon = new MapPolygon
{
Points = points,
ToolTip = toolTip,
ShapeFill = new MapShapeFill
{
Stroke = new SolidColorBrush(Colors.Blue),
StrokeThickness = 2,
Fill = new SolidColorBrush(Color.FromArgb(0x5A, 0x80, 0x80, 0x80))
}
};
RadMap.SetView(polygon.GeoBounds);
But when I create a MapEllipse and call SetView I get ZoomLevel = 1 and I don't understand why
var ellipse = new MapEllipse
{
Width = (double)radius * 2,
Height = (double)radius * 2,
Stroke = new SolidColorBrush(Colors.Blue),
StrokeThickness = 2,
Fill = new SolidColorBrush(Color.FromArgb(0x5A, 0x80, 0x80, 0x80)),
Location = points.ElementAt(0),
};
MapLayer.SetHotSpot(ellipse, new HotSpot { X = 0.5, Y = 0.5 });
RadMap.SetView(ellipse.GeoBounds);
Would appreciate help
Hi,
I find this article about the Validation Tooltip being clipped when using the Material theme.
I'm experiencing the same issue with the Windows 11 theme. Is the Win11 theme not using the tooltip element either ? The themes looks pretty close to each other so... is Win11 an extension of Material ?
Thank you for your help.

HI:
In the CloudUpload demo it uses a local service provider based on api.everlive.com but this link is broken. How can I run the demo? also how can I create the asp.net api to have it locally?
api.everlive.com

I use a RadCartesianChart3D for displaying a 3D graph. For copying this graph to Clipboard, I render the view model again and copy it to the Clipboard. But that copy does not contain the axis labels.
I use the following code to copy the view model to Clipboard:
var data = new DataObject();
var bitmap = RenderToBitmap(this);
if (bitmap != null)
{
data.SetData(DataFormats.Bitmap, bitmap);
}
Clipboard.SetDataObject(data);
And RenderToBitmap is as follows:
public BitmapSource RenderToBitmap(object viewModel, double dpi = 300.0)
{
var element = new Border()
{
Child = new ContentControl()
{
Content = viewModel,
},
Background = new SolidColorBrush(Colors.White),
};
element.Measure(new Size(double.PositiveInfinity, double.PositiveInfinity));
element.Arrange(new Rect(element.DesiredSize));
element.InvalidateVisual();
element.UpdateLayout();
var target = new RenderTargetBitmap((int)(element.ActualWidth * dpi / 96.0), (int)(element.ActualHeight * dpi / 96.0), dpi, dpi, PixelFormats.Default);
target.Render(element);
return BitmapFrame.Create(target);
}
Why is the copy not containing the axis labels?
