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:

L_param, returned in (1) is an IntPtr that, on a 64bit machine running a 64bit application could contains a value that SOMETIMES will crash in (2) where you try to convert it with an IntTo32 method...

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.

In this particular case, a HostWindow is hidden in the Loaded event of the Form. When we save the layout and load it again, the wrong autohide window is shown. The HostWindow.Hide() method in the loading scenario is forcing the wrong AutoHide HostWindow to be shown.

When closing the MDI child, its FormClosing event is called twice. This is not observed if we close its HostWindow first.

The problematic tool window has a user control that is docked to fill and it is built entirely with Telerik controls. The dock control, tab strips, windows and even the controls inside the user control are correctly scaled. The issue comes when you start undocking and then docking the tool window. The size of the user control increases with each operation. The controls have anchors and although they have correct scaling they get stretched. This results in messed layout. 

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;
}

Use cases:

1. You have a MainDocumentContainer with Document windows in it, placed in one under the other. Setting the DockState of the bottom DocumentWindow to Hidden, and restoring it afterwards, should place the DocumentWindow at the same place, instead of merging it with the above one

2. Same layout as above, when the layout is saved and then restored, the DocumentWindow positions should be exactly as they were

Use the following code snippet:

            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;

Please refer to the attached gif file illustrating better how the non-pinned tabs go behind the pinned tab. This behavior should be prevented and the tabs need to be arranged in a container on the right side of pinned tab.

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.Win32Exception
  HResult=0x80004005
  Message=Fout bij het maken van de vensterkoppeling. (Translation: Error making window link.)
  Source=System.Windows.Forms
  StackTrace:

   at System.Windows.Forms.Timer.set_Enabled(Boolean value)

   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

 

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.

Henk

Please run the sample project in an environment with left monitor at 150% DPI scaling and right monitor at 100%. You will notice that the ToolWindow remains with fixed width.

To reproduce:
1.Add a RadDock with two ToolWindows, docked in a shared TabStrip.
2.Change the dock state of the first ToolWindow to "Floating".
3.Change the dock state of the second ToolWindow to "Autohide".
4.Save the layout.
5.Change the layout.
6.Load the layout.

As a result both of the ToolWindow are autohidden.

Hello,

I have downloaded the latest winform version today and launched my application.

I experienced an immediate crash while replacing a document container by a split container.

You can see the small piece of code and the insttruction which is causing the crash ....

Obviously it was working properly before upgrading ...

Can you help? I am now just stuck so a fix or a workaround would be useful...

Thanks,
