HeaderSizeNeeded is fired twice with the same index and affects the header row width.
Hello,
I use RadPdfViewer to view a PDF file in my WPF application, the PDF file has only one page and the contents are in the middle of the page, so I'm trying to zoom and focus on the middle of the page, I use the following code:
private void DocumentChanged(object sender, DocumentChangedEventArgs e)
{
pdfViewer.ScaleFactor = 1.3;
var size = pdfViewer.Document.Pages[0].Size;
pdfViewer.ScrollToVerticalOffset(size.Height * 0.3);
pdfViewer.ScrollToHorizontalOffset(size.Width * 0.20);
}
however, I only see the horizontal scroll working.
How can I zoom then scroll to vertical and horizontal offset?
i hope add char controls
like :

Right now, it is not easy to disable styles for standard controls like Button.
Especially when using NoXaml.
You have to create an Empty style on Application level for the control to "rewind" its style.
I do believe this kind of style drags down performance of controls when unloading, since it causes StyleChanged events.
Some explanation about performance (how things work to my understanding). Might be BS, but I spend a few hours debugging through .net code to get this idea:
Issue is, that when control is unloaded, its not part of the logical / visual tree of the application anymore, so it falls back to styles defined on assembly level.
e.g. Themes/Generic.xaml. So the empty styles defined on Application level do not count anymore, but the ones you defined in your theme.
This can be observed on RadTabbedWindow. When unloading pages (like switching between them), controls fall back to the styles defined in the theme from Telerik.Windows.Controls.Navigation, because they are still children of that page.
You can observe this behaviour if you set a Breakpoint in FrameworkElement.OnStyleChanged before unloading a control tree.
If you'd remove the System.Windows.xaml from your theme-dictionaries so that one can decide to merge those styles or not, that would be great.
Hi
I would like to know if Progress Telerik has some plan to port their WPF controls to Avalonia (avaloniaui.net).
Thanks

Hi:
China has the largest population and we have a lot of Chinese customers. Increasing support for Chinese localization, IME and bug fixes should be a high priority.
Unfortunately, there are still no support plans for many features. In the Chinese environment, there are still many bugs.
Hope can be taken seriously!
There is too much unplanned feedback, not just in Chinese, but also in Japanese and Korean. These should be viewed as a single issue and considered a serious one.
That's more than enough votes. The following should be combined。

Hi,
our company is slowly rolling out high-DPI laptops to our users. On such devices, Windows automatically enables DPI scaling, using a value of 125% or 150%, depending on the screen's resolution. In combination with an external (unscaled) monitor, this causes our application, to appear blurry on the scaled screen.
Windows has built-in functionality to reduce the blurring, however, this only works on the main screen. If you connect a secondary screen and set that as your main screen, the application will always appear blurry on the laptop screen.
My understanding of the topic is that WPF is DPI aware - but on the system level. So it does not cope well with monitors that have different DPI settings. However, I found a tutorial on Microsoft Docs (https://docs.microsoft.com/en-gb/windows/win32/hidpi/declaring-managed-apps-dpi-aware?redirectedfrom=MSDN), hinting that it is possible to make WPF windows per-monitor DPI aware. Unfortunately, this workaround requires you to inherit your window class from their utility class.
Since all of our windows already inherit from RadWindow, I have no chance to include this without copying either their base class or RadWindow. Having RadWindow support per-monitor DPI awareness would be a great feature to have. Or is there already a way to support this?

PS: Why does the first feature form in the feature request workflow (the one, where it first searches for similar requests) not let me select the control/area I am searching for like the one for private tickets? I almost submitted this request for the Area "All (Multiple Controls)" because of that.
Default keystroke in other editors to activate text replacement is: ctrl+H
Would be nive to enable this in the syntax editor.
Good afternoon,
When we add a new child element to the RadDiagram(see attach file), the diagram automatically optimizes their layout. After the chart is updated, the new element and its parent are automatically moved to the left side. How to make them stay in their places?
There is a small discussion of this problem on the forum.

I would like the possibility to change the color of a line depending on the value.
For example:
I have values between -1 to 10.
If the value is -1 I would like the color (or possible the opacity) to change until it goes back to 0 or above.
As far as I know, there are no way to set the color of the title bar. As far as I know there are no properties "color" of the title bar.
Thanks
Hi Team,
Dennis Callahan from Telerik submitting this on behalf of Don -
If your team could create a theme for UI for WPF that mimicked the look of a UWP application and responded to the Windows 10 Light and Dark setting that would be excellent. I have not found such a theme in any of the products I have looked at so if Telerik could do it I think it might be the first.
I'm trying to draw a polygon on my RadMap using the MapPolygonView control. I can only see the polygon after I finished drawing it, but while I'm drawing - I can't see the lines.
Please add the capability for the RadMap to visualize the animation of shape's lines as it is being drawn.
Please add a property to disable the zoom witch CTRL+MouseWheel. Maybe something like IsMouseWheelZoomEnabled with a defaut value of true.
There are already other properties like IsPanningEnabled or ZoomToCursor.
The currently known solution is:
private void imageEditor_PreviewMouseWheel(object sender, MouseWheelEventArgs e)
{
if (Keyboard.IsKeyDown(Key.LeftCtrl) || Keyboard.IsKeyDown(Key.RightCtrl))
{
e.Handled = true;
}
}
Add a property to force only allowing uppercase values, without needing to specify a number of characters or have the underline in the control.
This is achievable in code, but it seems unnecessary to go to such lengths for each instance where it is needed.
private void bankCode_ValueChanging(object sender, Telerik.Windows.Controls.MaskedInput.RadMaskedInputValueChangingEventArgs e)
