Wrong RootCompass indicators location

[nagibator4000]

Hello everyone.

I have shell WinForms application that hosts WPF User Control contains RadDocking. When I drag RadPane, a RootCompass indicators of RadDocking shows in wrong location (see attachment). It looks like indicators shows without offset of embedded WPF Control relatively shell WinForms application.

Is it bug? Or maybe is there a way to change a location of RootCompass indicators? 

 

Thank you.

I've prepared a simple example reproduces that bug. You can find it using link below.

WinFormsWPF.sln is solution of WPF User Control contains RadDocking.

WFHost.sln is solution of WinForms host application.

Hi Egor,

Please check the following example from our online XAML SDK repository that demonstrates how to host RadDocking in WinForms application:
https://github.com/telerik/xaml-sdk/tree/master/Docking/DockingInsideWinForms

What you need to do in your application is to add reference to Telerik.Windows.Controls.dll in the WFHost project in order to implement a custom IWindowInteropabilityAdapter as shown here. Afterwards set the adapter to the WPF control. You can find below all the needed code:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        var wpfControl = new WpfHosted.UserControl1();
        WindowInteropabilityHelper.SetWindowInteropabilityAdapter(wpfControl, new Adapter(this));
        elementHost1.Child = wpfControl;
    }

    private class Adapter : IWindowInteropabilityAdapter
    {
        private Form1 form;
        public Adapter(Form1 form)
        {
            this.form = form;
        }

        public int AbsoluteLeft
        {
            get { return this.form.PointToScreen(this.form.elementHost1.Location).X; }
        }

        public int AbsoluteTop
        {
            get { return this.form.PointToScreen(this.form.elementHost1.Location).Y; }
        }

        public IntPtr Handle
        {
            get { return this.form.Handle; }
        }
    }
}

Hope this helps.

Hi, Kalin.

Your solution is works. Thank you very much.

Hi,

I checked the example and observed that the Root Compass Location is not at the center of the screen but a bit displaced.

 

I have attached the screen shot here.

Hello Egor,

I was able to reproduce this with a DPI scale set to 125%. Can you confirm that this is your setting too?

Hi Martin,

Yes, I reproduced it with DPI scale set to 125%. This is still reproducible when the DPI scale is set to 100% or 150%.

 

Thanks and regards,

Hello Shrikant,

I was able to reproduce this only on a DPI different than 100%. This happens because the PointToScreen method used in the Adapter class doesn't take into account the currently applied DPI. To resolve this, you can get the current DPI of the monitor and update the AbsoluteLeft and AbsoluteLeft property implementations of the Adapter class. For example:

public int AbsoluteLeft
{
	get 
	{
		Graphics graphics = Graphics.FromHwnd(IntPtr.Zero);
		var dx = graphics.DpiX / 96;
		graphics.Dispose();
		return (int)(this.form.PointToScreen(this.form.elementHost1.Location).X / dx);
	}
}

public int AbsoluteTop
{
	get 
	{
		Graphics graphics = Graphics.FromHwnd(IntPtr.Zero);
		var dy = graphics.DpiY / 96;
		graphics.Dispose();
		return (int)(this.form.PointToScreen(this.form.elementHost1.Location).Y / dy); 
	}
}
