In this case, we add a ToolWindow directly to the control in a floating state using FloatingWindow. Each add ToolWindow will have a different BackColor property value. Now we save the layout of the control into an XML file. The next step is to close the application and load the layout from the XML. The ToolWindows are loaded, however, their BackColor property is not restored.
this.toolWindow1.TabStrip.MinimumSize = new Size(200,200)
When closing the MDI child, its FormClosing event is called twice. This is not observed if we close its HostWindow first.
The DocumentTabStrip and ToolTabStrip are created dynamically and when they initialize they call their Scale method. The tool window, the user control, and also all other controls added to it are created only once. When you undock the window a new tab strip is created and the existing controls are added to it. When we load the tab strip we call PerformRadAutoScale which calls the stip's Scale method. Calling Scale propagates to the child controls causing additional scaling to the Microsoft controls. RadControls don't have issues because we have logic to check the scaling of the window and we don't allow double scaling.
As a workaround, we can create custom tab strips and override the ScaleChildren property to return false.
this.radDock1.DockTabStripNeeded += this.RadDock1_DockTabStripNeeded;
private void RadDock1_DockTabStripNeeded(object sender, DockTabStripNeededEventArgs e)
{
if (e.DockType == DockType.ToolWindow)
{
e.Strip = new MyToolTabStrip();
}
else
{
e.Strip = new MyDocumentTabStrip();
}
}
public class MyToolTabStrip : ToolTabStrip
{
protected override bool ScaleChildren => false;
}
public class MyDocumentTabStrip : DocumentTabStrip
{
protected override bool ScaleChildren => false;
}
Our application embed a RadDock element.Unfortunately, in a non-systematic way, our application crash with this stack trace:
Our application is a 64bit application (we migrated it to NET6 using Telerik 2022.2.510.60). As I told unfortunately in this case I'm not able to isolate the case in a simple project (as I'm used to to).
It would be useful by your side, however, make a check to the last trace line of the log I've gave to you:
at Telerik.WinControls.UI.ThemedFormBehavior.OnWMNCHitTest(Message& m)
If I decompile your code I find this:
99 time to 100 the code in line 755 works fine but I think that it is not guaranteed that L_Param returned in (1) can be fit in a 32bit box. This could explain why I use the phrase "...in a very random way" and why, at the moment, I'm not be able to give you a simple application where the problem is systematic.
I suspect that at line 755 we have got a problem, I'll appreciate your point of view about it.
Use the following code snippet:
ToolTabStrip tabStrip = this.toolWindow1.TabStrip as ToolTabStrip;
this.toolWindow1.Text = "<html><span style=\"font-family:Segoe UI;font-size:8.25;\"><b>Hello</b></span><span" +
" style=\"font-family:Segoe UI;font-size:8.25;\">Woooooooooooooooooorld</span></html>";
TextPrimitive text = tabStrip.CaptionElement.FindDescendant<TextPrimitive>();
text.ClipDrawing = true;
text.StretchHorizontally = false;
text.DisableHTMLRendering = false;
text.AutoEllipsis = false;
Hi,
I have C# Winforms application targeting .Net 5.
I am trying to use the Raddock with the Visual Studio 2012 dark theme, adding to a radribbonform
There are several tool windows that i have tabbed using the Advance layout designer. When i try to select a tab in the main Visual studio designer i am unable to change it from the one i selected in the Advanced layout designer.
I am also unable to resize the windows using the split container while in standard design view.
I have attached a word document to try and explain.
My VS version is:
Microsoft Visual Studio Professional 2019
Version 16.9.1
thanks
Mark.
Hi,
I am trying to make a Winforms app high dpi aware. All seems fine except when using a toolwindow on a raddock. Is there some special to setup when I want a Raddock to also autoscale?
I created a GIF to example the behaviour. The left side is at 15% and the right side just at 100%. I move the form from right to left and back. As you can see most controls get resized, except for the size of the toolwindows in the raddock.
The raddock is the only dock on the form and is set to dock in parrent.
At the end of the gif you can see some behaviour when I place the form over both screens. Then the applications breaks. I get this error:
System.ComponentModel.Win32ExceptionHResult=0x80004005
Message=Fout bij het maken van de vensterkoppeling. (Translation: Error making window link.)

Maybe this is normal behaviour, but I still want to mention it, because it is possible that in an work environment, someone might to this from time to time. Maybe not on purpose, but still.
Regariding the high DPI, am I doing something wrong?
Thx.
