[Solved] Floating dockable pane opens with wrong width

[Daniel K.]

Hello everyone,
I use a selfmade drag 'n' drop control which opens a radpane when dropped in the Docking area.
My Problem the first time I drop the control in the docking area the undocked floating pane appears but with
a way smaller width than the content, which results in cutting the content.
When I resize the height with the mouse just a little bit the pane pops out to full width, and looks as it should (Please look at the attached Jpeg).
Now when I reopen it it has the correct width. It looks like there is a wrong initial width but the pane ignores every
parameter I send with.

Thank you in Advance for your help.

Hello Daniel,

When a floating RadPane instance created it is assigned a default Width and Height values. When adding RadPane instances to the control dynamically at run time and those instances should be floating with custom floating size you will need to do the flowing:

• Create the correct element structure (RadPane in RadPaneGroup in RadSplitContainer) and add it to the RadDocking control
• In order to make the new RadPane instance initially floating you can either set the InitialPosition of the new RadSplitContainer to FloatingDockable or call the MakeFloatingDockable() method of the RadPane
• In order to assign an initial floating size to the RadPane all you need to do is set the FloatingSize attached property to the RadSplitContainer of the pane.

The next code snippet shows the described approach, hope this is helpful:

private void OnAddFloatingPaneButtonClick(object sender, RoutedEventArgs e)
{
    this.AddNewPane(this.Docking, true);
}

private void OnAddDockedPaneButtonClick(object sender, RoutedEventArgs e)
{
    this.AddNewPane(this.Docking, false);
}

private void AddNewPane(RadDocking radDocking, bool isFloating)
{
    RadPane radPane = new RadPane() { Title = "New sample RadPane" };
    radPane.Content = new TextBox() { Text = "TextBox" };
    RadPaneGroup radPaneGroup = new RadPaneGroup();
    var dockState = isFloating ? DockState.FloatingDockable : DockState.DockedLeft;
    RadSplitContainer radSplitContainer = new RadSplitContainer() { InitialPosition = DockState.FloatingDockable };
    RadDocking.SetFloatingLocation(radSplitContainer, new Point(400, 400));
    RadDocking.SetFloatingSize(radSplitContainer, new Size(900, 500));
    radPaneGroup.Items.Add(radPane);
    radSplitContainer.Items.Add(radPaneGroup);
    radDocking.Items.Add(radSplitContainer);
}
