Hi,

If I double click the header of Toolwindow, it will become floating. May this function be closed? Thanks.

Hi, 

If you mean you only want to be able to resize, autohide and pin, then this should do it for you. Add to FormLoad (for example)

Me.ToolWindow1.AllowedDockState = Telerik.WinControls.UI.Docking.AllowedDockState.All And Not Telerik.WinControls.UI.Docking.AllowedDockState.Floating

Thanks for your reply, Richard. But it is not my problem.

Please refer to following online help, I want to cancel the function of
mouse support.

http://www.telerik.com/help/winforms/dock_usabilitykeyboardsupport.html

Mouse support:
Double click: Double-clicking the title bar of a ToolWindow un-docks the panel so that it
floats. Double-clicking the title bar of a floating ToolWindow docks the ToolWindow.

Besides, if I right-click on the header of  ToolWIndow, the contextmenu with option for docking or floatong will appear, can this be close? Thanks for your reply.

Tried to upload a sample project for you but not allowed here. 
This could should help


Private Sub Form_Load(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles MyBase.Load
 
    ' Tool window properties
    Me.ToolWindow1.DocumentButtons = Telerik.WinControls.UI.Docking.DocumentStripButtons.None
    Me.ToolWindow1.ToolCaptionButtons = Telerik.WinControls.UI.Docking.ToolStripCaptionButtons.AutoHide
 
    ' Document window properties
    Me.DocumentWindow1.DocumentButtons = Telerik.WinControls.UI.Docking.DocumentStripButtons.None
    Me.DocumentWindow1.ToolCaptionButtons = Telerik.WinControls.UI.Docking.ToolStripCaptionButtons.None
 
    ' Tell the Tool Window it may not float or be a tabbed document
    Me.ToolWindow1.AllowedDockState = Telerik.WinControls.UI.Docking.AllowedDockState.All And _
        Not Telerik.WinControls.UI.Docking.AllowedDockState.Floating And _
        Not Telerik.WinControls.UI.Docking.AllowedDockState.TabbedDocument
End Sub

Hello guys

KJ, if I understand your requrement correctly, you want to remove only the double-click support, but you still want to be able to float a window by a mouse drag operation. If this is the case, please refer to the code snippet below. Basically, you need to handle the TransactionCommitting event and check which is the reason for the transaction. In addition, you can prevent the context menu from appearing by handling the ContextMenuDisplaying event of the ContextMenuService:
    public Form1()
    {
        InitializeComponent();
  
        ContextMenuService menuService = this.radDock1.GetService<ContextMenuService>();
        menuService.ContextMenuDisplaying += menuService_ContextMenuDisplaying;
  
        this.radDock1.TransactionCommitting += new RadDockTransactionCancelEventHandler(radDock1_TransactionCommitting);
    }
  
    void radDock1_TransactionCommitting(object sender, RadDockTransactionCancelEventArgs e)
    {
        RedockTransaction transaction = e.Transaction as RedockTransaction;
        if (transaction != null)
        {
            if (transaction.Reason == RedockTransactionReason.ToolTabStripCaptionDoubleClick 
                || transaction.Reason == RedockTransactionReason.FloatingWindowCaptionDoubleClick)
            {
                e.Cancel = true;
            }
        }
    }
  
    private void menuService_ContextMenuDisplaying(object sender, ContextMenuDisplayingEventArgs e)
    {
        if (e.DockWindow is ToolWindow)
        {
            e.Cancel = true;
        }            
    
}

I hope this helps.

On a related note, I would like to mention that there is an issue with floating toolwindows not returning to their previous state on double-click of their headers if the previous state was a "tabbedDocument".

Steps to reproduce :

1. Dock Fill a toolwindow to have a tabbed document.
2. Right-click the tabbed document and select Floating option (I would rather prefer if this also could be achieved by double-clicking on the header of tabbeddocument).
3. Now you have a floating toolwindow, double-click on its header and it should go back to its previous state which was a "tabbedDocument" (or DockFill), but this doesn't happen and the toolwindow gets left docked on the form.

Please help with this.

Thanks

I have the exact same problem. A double-click on a floating window always default to a LeftDock.

Hello guys,

The behavior that you experience is the designed behavior of RadDock - floating windows can only become docked ToolWindows by the double click operation. I have added your requirement as a feature request in our PITS.

Despite the fact that there is no straightforward solution, I think that you can achieve the desired behavior by handling two events: DockStateChanging and TransactionCommitting. I am attaching a sample project that demonstrates the approach.

I hope this helps.

All the best,
