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

The issue is that our system will not be fully maximized when using it on Windows 7, while on our PCs here (windows 10), it's fine.

To reproduce: Add a RadForm and at design time in the Properties section of Visual Studio try to customize some properties of the RadForm >> FormElement >> TitleBar, e.g. Padding, ForeColor. You will notice that even though you save the changes, they are not serialized. Thus, when you run the application, none of the changes are applied.

Workaround: set the changes programmatically at run time.

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);
        }

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:
- Set the StartPosition to CenterScreen
- Show the form on a HDPI monitor

Workaround:
var form = new RadForm();

float dpiX, dpiY;
Graphics graphics = this.CreateGraphics();
dpiX = graphics.DpiX /100;
dpiY = graphics.DpiY /100;

form.StartPosition = FormStartPosition.Manual;
var monSize = Screen.FromControl(this).Bounds;
var centerX = (monSize.Width / 2) - (form.DesktopBounds.Width * dpiX / 2);
var centerY = (monSize.Height / 2) - (form.DesktopBounds.Height * dpiY/ 2);
form.Location = new Point((int)centerX,(int) centerY);
form.Show();

To reproduce:
- Hide the border and change the BackColor of the form. 
- Dock a MenuStrip to the top. 
- You will notice that there are 2 pixels on the left and right sides of the menu. 

Project is attached as well.

How to reproduce: set the Size property of the form in the designer of Visual Studio, pay attention to the serialized ClientSize value. Run the form and check the ClientSize, it has increased

Workaround: 
public partial class Form2 : RadForm
{
    public Form2()
    {
        InitializeComponent();
        Padding p = TelerikDpiHelper.ScalePadding(this.FormBehavior.ClientMargin, new SizeF(1f / this.RootElement.DpiScaleFactor.Width, 1f / this.RootElement.DpiScaleFactor.Height));
        this.MaximumSize = new Size(this.Size.Width - p.Horizontal, this.Size.Height - p.Vertical- this.FormBehavior.ClientMargin.Bottom + this.FormElement.TitleBar.Size.Height);
    }

    protected override void OnShown(EventArgs e)
    {
        base.OnShown(e);

        this.MaximumSize = new Size(0, 0);
    }
}

How to reproduce: just create a RadForm, in the designer change its size and set its FormBorderStyle property to be None. When the form loads its size will be increased.

Workaround: set its MaximumSize property
this.MaximumSize = new Size(400, 80);

To reproduce: follow the steps from the attached gif file.

Workaround:

        public RadForm1()
        {
            InitializeComponent();

            ((RadRibbonFormBehavior)this.FormBehavior).AllowTheming = false;
        }

The issue can be reproduced by creating a form with a width of 1200 pixels in an application that is DPI aware. Then the project is run on a tablet with low resolution and an increased DPI, e.g. 1024 x 768 and scaling 120%.

Workaround:
Public Class RadForm1
    Sub New()

        InitializeComponent()

        Dim g = Me.CreateGraphics()
        Dim scale = 96.0 / g.DpiX
        Me.Size = New Size(scale * Me.ClientSize.Width, scale * Me.ClientSize.Height)
        g.Dispose()
        Me.WindowState = FormWindowState.Normal
    End Sub
End Class

Please refer to the attached screenshot and sample project.

Workaround: call the RadForm.EndInit method before showing the form.

To reproduce:

public partial class RadRibbonForm1 : Telerik.WinControls.UI.RadRibbonForm
    {
        public RadRibbonForm1()
        {
            InitializeComponent();
            this.AllowAero = true;
            this.RibbonBar.QuickAccessToolbarBelowRibbon = false;
        }
    }

Note: the system buttons not always handle the mouse click.

Workaround: set AllowAero to false OR RibbonBar.QuickAccessToolbarBelowRibbon to true.

The attached video shows how you can reproduce this.

The issue is easily reproducible on a remote Windows 7 machine.

To reproduce:

public Form1()
{
    InitializeComponent();
    this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;
}

Although the user is not allowed to resize the form from the form's borders, it is possible to do it by the context menu.

Workaround:

[DllImport("user32.dll")]
static extern bool EnableMenuItem(IntPtr hMenu, uint uIDEnableItem, uint uEnable);

internal const UInt32 MF_DISABLED = 0x00000002;

internal const UInt32 SC_SIZE = 0xF000;

internal const UInt32 WM_INITMENUPOPUP = 0x0117;

protected override void WndProc(ref Message m)
{
    if (m.Msg == WM_INITMENUPOPUP && (((int)m.LParam & 0x10000) != 0))
    {
        EnableMenuItem(m.WParam, SC_SIZE, MF_DISABLED);
    }

    base.WndProc(ref m);
}

To reproduce:
Use the following method to add a form with a textbox to a panel:
Private Sub AddPage(ByRef f As Form)
    Try
        pnlScreenContainer.SuspendUpdate()
        f.TopLevel = False
        f.Visible = False
        f.Dock = DockStyle.Fill
        pnlScreenContainer.Controls.Add(f)
        f.Visible = True
        f.BringToFront()
        f.FormBorderStyle = Windows.Forms.FormBorderStyle.None
        f.Show()

        f.Activate()
    Catch
    End Try
    pnlScreenContainer.ResumeUpdate()
End Sub

Workaround:
- Use RadTextBoxControl instead.
