Protected Overrides Sub ScaleControl(ByVal factor As SizeF, ByVal specified As BoundsSpecified)
    MyBase.ScaleControl(factor, specified)

    If Me.HasOwnToolbar AndAlso Me.AllowTheming AndAlso Not Me.IsDesignMode AndAlso Me.IsInitialized Then
        Me.AllowTheming = False
    End If

Use attached to reproduce. This was working in version 2017.1.221

Workaround:
private void Instance_LocationChanged(object sender, EventArgs e)
{
    var box = sender as RadMessageBoxForm;
    box.Location = new Point((this.Location.X + this.Width / 2) - (box.Width/2), (this.Location.Y + this.Height / 2 )- (box.Height/2));  
    
}

To reproduce: on some Windows 10 machines the title bar's text is not rendered clearly. 

Workaround:

1. Set the RadForm.AllowTheming property to false.

2. In the form's Load event change the TextRenderingHint of the caption text primitive to AntiAliasGridFit:  

TextPrimitive tp = this.radRibbonBar2.RibbonBarElement.RibbonCaption.CaptionLayout.CaptionTextElement as TextPrimitive;
tp.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAliasGridFit;

How to reproduce: add a RadRibbonForm and set its MaximizeBox, MinimizeBox properties to false. Set the HelpButton property of the form to true and change its Icon. You will notice that the designer in Visual Studio has not updated.

Workaround: use the element hierarchy editor and manually change the visibility of the elements.

To reproduce: run the sample project. It ends up leaving significant blank space on the right and the bottom, whereas the normal MS Form does NOT do this and works right.

Workaround: in the Load event you can adjust the size with 10/15 px by setting the MaximumSize:

        private void Form1_Load(object sender, EventArgs e)
        {
            this.MaximumSize = new Size(this.Size.Width - 15, this.Size.Height - 10);
        }

Form goes under windows taskbar based on following conditions.

 

WindowState = Maximized

MinimizeBox = false

MaximizeBox = false

 

Also when there is no icon (ShowIcon = false) Form text, first letter is clipped.

02.{
03.    if (!IsFormOpen(typeof(frmSupplierList)))
04.    {
05.        CloseChildForm();
06.        frmSupplierList m_frmListSupplier = new frmSupplierList
07.        {
08.            Width = this.Width,
09.            Height = this.Height,
10.            MdiParent = this,
11.            MaximizeBox = false,
12.            MinimizeBox = false,
13.            ControlBox = false,
14.            WindowState = FormWindowState.Maximized
15.        };
16.        m_frmListSupplier.Show();
17.    }
18.}

 

But Still i can see the ControlBox and Minimize and Maximize Buttons on the Top right Corner.

Dear support,

i have a RadForm and custom theme.

To reproduce the problem:

1. Configure 2. montior to have 200% Scale (Monitor2).

2. Start the solution on your main Monitor1 (with 100% Scale)

3. Click on button "radbutton1".

4. Move the shown RadForm1 from Monitor1 to Monitor2 and release it. The form will scale automatically.

5. Now move the RadForm1 back to the main Monitor1

Now you can see the effect from Form.png.

What is causing it and how to remove it?

The problem has some connection with the Anchor options from radButton1 and radButton2.

If i set them to "Top, Left", then the effect does not appear, but this way i have to set their location manually, or is there other option?

 

Regards,

Stoyan

Release R3 2022

Please run the sample project on 100% and 150% DPI scaling. You will notice that with 100% the shown form is centered to its parent, but with 150% it is shifted:

I have an issue such that when I place my application (which is based on a RadRibbonForm) on to my right hand 4K monitor and then maximise it I get a small amount of "bleed" of my application on to the right hand side of my left monitor.

On inspecting the forms desktop bounds property it see X = 1908, Y = -12, width = 3864, height = 2114. I was expecting X = 1920, Y = 0, width = 3840, height = 2090 which is what is being reported in Screen.AllScreens.

I'm using the latest version of WinForms and have done what is suggested in this link.

I can reproduce the same behaviour when I run "Demo Application - Telerik UI for WinForms R2 2022 SP1", move it to my large right hand monitor then maximise it.

Kind regards
Toby

In Net 7 projects, resizing RadForm will serialize the AutoScaleBaseSize property which is deprecated with the latest versions.

Release Release R1 2023 SP1
In this particular case, we have RadGridView inside RadDock control. The RadGridView is grouped. The ScrollViewer inside the group is trying to load while maximizing the Form. At some point, the ScrollViewer collapsed which leads to re-arranging the items inside the panel and the application hangs.

Create a new project with an anchored control in all corners. You can simply do the test, insert a scheduler or gridview, snap on all corners, set WindowsState to maximized and start the program with a DPI of even 125%, and see the problem right away. Tested with new projects both in Net Framework and .Net. I also tried creating a new instance of Winforms and setting the Windowstate from there by code, but the problem remains.
