Setting the size of a docked toolwindow?

[Malcolm]

Can set the default size for auto hide, but can't seem to set the size for when the window is docked. Would rather set a minimum size on it to make it usable.

Is there a way to do this?

[Richard Slade]

Hello Stephen,

you can set the size of your docked ToolWindow in the following way

Dim window As ToolWindow = Me.ToolWindow1
Dim strip As DockTabStrip = DirectCast(window.TabStrip, DockTabStrip)
strip.SizeInfo.AbsoluteSize = New System.Drawing.Size(100, strip.SizeInfo.AbsoluteSize.Height)

Hope that helps
Richard

Support should consider adding this to this help topic

Building an Advanced Layout at Runtime - WinForms Dock Control - Telerik UI for WinForms

So, when the first two windows are added, a custom width is set to the docked window. It would be a lot easier to find.  It took me nearly 20 minutes just to find this.

Hi, Kris, Note that the DockTabStrip is a derivative of SplitPanel. Hence, the sizing mechanism would be very similar to the one for the SplitPanel. The following help articles are quite useful on this topic:

Thanks Richard. Set me on the right path:

Dim navwin As HostWindow = Me.RadDock1.DockControl(Navigator, Telerik.WinControls.UI.Docking.DockPosition.Left, Telerik.WinControls.UI.Docking.DockType.ToolWindow)
Dim strip As DockTabStrip = DirectCast(navwin.TabStrip, DockTabStrip)
strip.SizeInfo.AbsoluteSize = New System.Drawing.Size(300, strip.SizeInfo.AbsoluteSize.Height)

Works perfect!

I create a new tab, to a raddock, but when I try and switch back to another tab, I get

 

System.NullReferenceException: Object reference not set to an instance of an object.
   at Telerik.WinControls.UI.Docking.DockTabStrip.ProcessFocusRequested(RadElement element)

 

How do i fix this?

 

Thanks.

I have a document container with 3 tabs on it as the attached snap show.  Each of them works fine right now, and I can switch between them.

I needed to add another one. From the radDock tab I clicked and did, "Add Tabbed Document". This works fine.

 

Whens I run the code though, when I try and click on the other tabs it crashes, and the I get the above stack trace.

Hello, Raji, 

Thank you for writing back. 

Following the provided information, I tried to replicate the error but without any success. Please refer to the attached gif file illustrating the behavior on my end. Am I missing something? I have also attached my sample project. Is it possible to provide a video demonstrating what steps do I need to perform in order to obtain the unexpected behavior? Thank you in advance for your cooperation.

I am looking forward to your reply.

Hi dear admin !

Can i fix radDock toolwindow size ?

I want  restrict toolwindow minimum or maximum size on runtime by user.

[Nadya | Tech Support Engineer]

Hello Gh Reza,

Thank you for writing.

In order to restrict the size of a toolwindow, you can use the MinimumSize and MaximumSize properties. Here is an example that demonstrates how you can fix the tool windows height:

 public RadForm1()
        {
            InitializeComponent();

            ToolWindow window1 = new ToolWindow();
            ToolWindow window2 = new ToolWindow();
            ToolWindow window3 = new ToolWindow();

            this.radDock1.DockWindow(window1, DockPosition.Top);
            this.radDock1.DockWindow(window2, DockPosition.Top);
            this.radDock1.DockWindow(window3, DockPosition.Top);

            window1.TabStrip.SizeInfo.MinimumSize = new System.Drawing.Size(0, 100);
            window2.TabStrip.SizeInfo.MinimumSize = new System.Drawing.Size(0, 100);
            window3.TabStrip.SizeInfo.MinimumSize = new System.Drawing.Size(0, 100);


            window1.TabStrip.SizeInfo.MaximumSize = new System.Drawing.Size(0, 300);
            window2.TabStrip.SizeInfo.MaximumSize = new System.Drawing.Size(0, 300);
            window3.TabStrip.SizeInfo.MaximumSize = new System.Drawing.Size(0, 300);
        }

Additional information about RadDoc is available in the following help article: https://docs.telerik.com/devtools/winforms/controls/dock/object-model/example-building-an-advanced-layout-at-runtime

I hope this helps. Should you have other questions do not hesitate to ask.
