Use the attached sample project.
Sceen 1 (Screen with program shortcuts) on the right in the gif: this screen has display scale 125%
Screen 2 (Screen with the Form) on the left in the gif: this screen has display scale 100%
When all three toolwindows are placed in the forms, there is no issue. The Dropdown list of ToolWindow1 (floating, dockable..) when opened is placed correctly.
If I moved the ToolWindow3 from Screen2 to Screen1 and make it the most recent active window (by clicking on it), I go back to the Screen2 and open the dropdown list of Toolwindow1, this list's position is now wrong and the text size bigger. This is because it takes the display scale (125%) of the screen where the most recent active toolwindow (ToolWindow3 ) is.
If I popup the ToolWindow2, place it in Screen2 (the same screen with ToolWindow1), make ToolWindow2 the most recent active window, and open the dropdown list of Toolwindow1, this list's position is now correct and the text size normal. This is because it takes the display scale (100%) of the screen where the most recent active toolwindow (ToolWindow2 ) is.
Workaround: add app.manifest file and declare the application as DPI aware:
public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
public RadForm1()
{
InitializeComponent();
this.SizeChanged += RadForm1_SizeChanged;
this.timer1.Start();
}
private void RadForm1_SizeChanged(object sender, EventArgs e)
{
this.Text = this.Size.ToString();
}
private void timer1_Tick(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.WindowState = FormWindowState.Normal;
}
else
{
this.WindowState = FormWindowState.Minimized;
}
}
}
In this case, we have an MS standard Form with control position on the form. Each of the controls has the right anchor. Moving the form to a monitor with a higher resolution messed up the size of the controls.
IMPROVE. RadShortcut - having displayed two forms both using the same shortcut for some action, the shortcut is applied to the first opened form instead to the one on focus.
Project Update Utility throws unhandled exception when you try to upgrade project which files are not checked-out from source control.
How to reproduce: check the attached video Workaround: select a color from a different tab or use the color picker
To reproduce: please refer to the attached sample project and gif file. Workaround: use screentips: https://docs.telerik.com/devtools/winforms/telerik-presentation-framework/tooltips-and-screentips/screen-tips
Workaround: manually increase the font of the controls protected override void OnShown(EventArgs e) { base.OnShown(e); var dpi = NativeMethods.GetSystemDpi(); this.Font = new Font(this.Font.Name, this.Font.Size * dpi.X / 96, this.Font.Style); this.radMenu1.Font = new Font(this.radMenu1.Font.Name, this.radMenu1.Font.Size * dpi.X / 96, this.radMenu1.Font.Style); this.radCommandBar1.Font = new Font(this.radCommandBar1.Font.Name, this.radCommandBar1.Font.Size * dpi.X / 96, this.radCommandBar1.Font.Style); }

Implement functionality to rotate the text in a cell.
To reproduce: add a RadLabel and change its cursor to Hand. this.radLabel1.Cursor = Cursors.Hand; The PixelatedHandCursor.png shows the poor quality of the cursor which should be improved. Workaround: https://stackoverflow.com/questions/6016995/un-antialiased-hand-cursor-in-windows-forms-apps/6017174#6017174 public class LinkLabelEx : RadLabel { private const int WM_SETCURSOR = 0x0020; private const int IDC_HAND = 32649; [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)] private static extern IntPtr LoadCursor(IntPtr hInstance, int lpCursorName); [DllImport("user32.dll", CharSet = CharSet.Auto)] private static extern IntPtr SetCursor(IntPtr hCursor); protected override void WndProc(ref Message m) { if (m.Msg == WM_SETCURSOR) { // Set the cursor to use the system hand cursor SetCursor(LoadCursor(IntPtr.Zero, IDC_HAND)); // Indicate that the message has been handled m.Result = IntPtr.Zero; return; } base.WndProc(ref m); } } The ImprovedCursorRendering.png shows the improved cursor.
The performance of the DayView when the control is bound to a large number of recurring appointments and it is grouped by resources needs to be improved.
Hi,
We are using Telerik UI WinForms in our project. Current built-in themes are not suitable for our project requirements. We need Visual Studio 2019 Theme for UI WinForms.
As mentioned in the Telerik blog, the latest R3 2019 release of Telerik UI for WPF and Telerik UI for Silverlight is having Visual Studio 2019 Theme.
When can we expect Visual Studio 2019 Theme for UI WinForms?
Documentation about High-DPI mechanisms available on the website is very outdated and mostly does not consider the changes and improvements that Microsoft made with .net 7.0 and 8.0.
What's needed is thorough documentation about Telerik's behavior in comparison with the different situations on .net Framework 4.9 and the major .net Versions 6.0, 7.0, and 8.0.
Kind regards
Erwin
