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.

When a set of RadForms is used inside an MDI Form and are maximized, after some time, the child forms flicker continuously.

See the attached video.

The same behaviour DOES NOT happen when regular Windows Form is used.

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.

A possible workaround is to set the RadControl.EnableDpiScaling property to false.
static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        RadControl.EnableDpiScaling = false;

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new RadForm1());
    }
}

Another workaround is to mark the application as DPI-aware: https://docs.telerik.com/devtools/winforms/telerik-presentation-framework/dpi-support

Based on the support we will decide to purchase this tool.

We need your assistance asap.

1.download and install the telerik trial version for ui winforms for desktop latest version 2019. 219.

2.open new project with blank template.

3.create radform and set Radform1 as mdi form. And open a child page from this..

CHild page takes 4 seconds to load. Though child page has only grid view and loads only 6000 records

Thanks

Sathish.

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.

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.

Use attached to reproduce.
Case 1 - the initial scaling is not correct and the showing dilog1 results in a different DPI each time. 
Case 2 - the AllowTheming property disabled the scaling - see dialog 2.

Workaround:

this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi;
this.AutoScaleDimensions = new System.Drawing.SizeF(96F, 96F);

public class MyRadForm : RadForm
{
    protected override void HandleDpiChanged()
    {
        if (TelerikHelper.IsWindows10CreatorsUpdateOrHigher)
        {
            return;
        }

        base.HandleDpiChanged();
    }

}

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: 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: Create a RadForm, select a material theme from the ToolBox, and apply the theme to the Form. Set the size of the Form to anything simple like (300, 300) and then save and close out the Form. When you reopen the same Form it will grow to (304, 302).
Please refer to the attached gif file.

Workaround: set the size at run time.

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;
