Customize the title bar of a DockPanel

[kdev]

Hi,

I create a custom DockPanel and I want to override the menu shown when we click the DropDownButton.
is that possible?
if not, can we add a second DropDownButton to the title bar of the DockPanel ?
Or is there a way to customize this title bar ? 

Thanks,
Kort

Hi kort,

You can change the dropdown menu as follows:
 

private void ChangeDropDownMenu(DockPanel dockPanel)
        {
            if (dockPanel.DefaultPresenter != null && dockPanel.DefaultPresenter is DockPresenterControl)
            {
                RadItem dockPresenterElement = ((DockPresenterControl)dockPanel.DefaultPresenter).DockPresenterElement;
                ClassSelector selector = new ClassSelector("DockPresenterCaptionDropDown");
                RadDropDownButtonElement dropDownButton = selector.GetSelectedElements(dockPresenterElement)[0] as RadDropDownButtonElement;
                this.AddMenuItems(dropDownButton);
            }
        }

        private void AddMenuItems(RadDropDownButtonElement dropDownButton)
        {
            dropDownButton.Items.Clear();

            RadMenuItem menuItem = new RadMenuItem();
            menuItem.Text = "Some Text";
            dropDownButton.Items.Add(menuItem);

            menuItem.Click += new EventHandler(menuItem_Click);
        }

        void menuItem_Click(object sender, EventArgs e)
        {
            MessageBox.Show("Menu item was clicked.");
        }

It is important that you call the ChangeDropDownMenu method after a call to SetDock:
 

this.dockingManager1.SetDock(dockPanel, dockPosition);

this.ChangeDropDownMenu(dockPanel);

Hope that helps.

Hi Jordan,

it works fine, thanks

But when I change the DockPanel dock state (Drag&Drop it), I got the original menu. perhaps that we call the SetDock method. So I try to call ChangeDropDownMenu in the Dockpanel.Activated event but it works only if we select an other panel before. I try also with the Dockingmanager.DockingStateChanged event without success :(

In which Docking event, have I to call the ChangeDropDownMenu?

Regards

Hi Kort, 

You can use this code snippet:

(dockingManager1.PrimarySite as DockSite).PostLayout +=new EventHandler(Form1_PostLayout);

void Form1_PostLayout(object sender, EventArgs e)
{
   ChangeDropDownMenu(dockPanel1);
}

Kind regards,
