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
The issue exists in Fluent, Material, and Crystal themes.
To reproduce:
Create an MDI application and maximize the child form.
The child form buttons are not styled.
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.
Using the spellchecker, and the popup when using themes overlaps as per image below. If i make :
e.SpellingForm.Controls("buttonIgnoreAll").Visible = False
Regards
Gavin
To reproduce:
1. Use the 2020.3.1020 Telerik version
2. Show RadForm and set MinimumSize property
3. Double Click the Title Bar to maximize the form or click the Maximize button
4. Double Click the Title Bar again and see that no border is shown.

To reproduce:
- Set your monitor DPI to 200%(or any order value different from 100%). You need to Log off(or restart) in order to apply correctly the new DPI settings.
- Create a UserControl with some RadControls inside.
- Add the UserControl at design time as a child control to a RadForm.
- Run the RadForm and you will see that the controls inside the user control are scaled twice.
Workaround:
In the OnLoad method of RadForm do through all nested RadControls inside the UserControl and downscale them to the same DPI as the RadForm.
{
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
SizeF dpiScaleFactor = RootElement.DpiScaleFactor;
FixDpiScaling(this.Controls, dpiScaleFactor);
}
private void FixDpiScaling(Control.ControlCollection controls, SizeF dpiScaleFactor)
{
foreach (Control item in controls)
{
RadControl radControl = item as RadControl;
if (radControl != null)
{
SizeF dpi2 = radControl.RootElement.DpiScaleFactor;
if (dpiScaleFactor.Width != dpi2.Width)
{
SizeF fixDpiCoefficient = new SizeF(dpiScaleFactor.Width / dpi2.Width, dpiScaleFactor.Height / dpi2.Height);
radControl.Scale(fixDpiCoefficient);
}
}
FixDpiScaling(item.Controls, dpiScaleFactor);
}
}
}

Follow the steps which are illustrated in the gif file:
1. Create new .NetFrameWork Telerik WinForm project
2. Set the MinSize of the RadForm1 to 300, 300
3. Set the MaxDize of the RadForm1 to 600, 600
4. Save the Form
5. Close the form
6. Build the project
7. Add new Telerik form, inherit from RadFrom1 via the Add New Item form and picking Inherited Form (Windows Forms). When prompted, pick RadForm1.
8. Resize the new form
9. Save and Close the form.
10. Open RadForm1
11. Reset the Max Size
12. Save and Close RadForm1
13. Rebuild the project
14. Open the inherited form
Workaround: instead of adding an Inherited Form, add a Telerik RadForm. Then, change it to inherit from RadForm1:
To reproduce, use the following code and minimize the child form:
public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
public RadForm1()
{
InitializeComponent();
this.IsMdiContainer = true;
RadForm form = new RadForm();
form.Text = "MDI Child";
form.MdiParent = this;
form.MinimumSize = new Size(800,600);
form.Show();
}
}
In this particular case, we have custom RadButtonElements placed in the title bar of the form. We have subscribed to the click event on each button. In the click event handlers, we are showing file dialogs. When clicking one time to show a dialog and the mouse leaves the title bar bounds, this triggers the click event twice, thus opening another dialog.
As a workaround, we could use the MouseDown event instead or raise a flag in the click event handler.
