TabbedMdi "Create New Horizontal Group" for each open tab

What is the best way to programmatically go through all open tabs and create a new horizontal group?

I tried the code below:
foreach(Form form in this.tabbedMDIManager.MdiChildren)
{
form.Activate(); if(this.tabbedMDIManager.CanCreateNewHorizontalGroup())
{ this.tabbedMDIManager.CreateNewHorizontalGroup();
}
}

It works but it has a horrible repainting issue where as if I go to each tab and use the right click menu "Create New Horizontal Tab Group" everything is fine. So is their anyway to access the right click context menu of a tab programtically?

Thanks

Hi Alan,

My apologies for the delay in responding to you.

If your intention is to create a HorizontalGroup without using ContextMenu means, please use the following code snippet in button_click Event.

Form childform = new Form();
childform.WindowState = FormWindowState.Normal;
childform.Text = "MDI Child Form " + count.ToString();
childform.MdiParent = this;
childform.Show();
this.tabbedMdiManager.CreateNewHorizontalGroup();

Using Beforpopup Event and clear method you can disable and clear the contextmenu respectively.

void ContextMenuItem_BeforePopup(object sender, CancelEventArgs e)
{
e.Cancel = true;
}
this.tabbedMdiManager.ContextMenuItem.Items.Clear();

You can add the new item in context menu using Add() Method in tabbedMDIManager. The following code snippet which illustrate how to add a neww context menu item in tab.

BarItem x = new BarItem();
x.Text = "New";
this.tabbedMdiManager.ContextMenuItem.Items.Add(x);
x.PerformClick();
x.Click += new EventHandler(x_Click);

Pleasse refer the attached sample.

The above sample which illustrates how to create horizontalgroupbar and how to customize the tab using contextmenu programatically.

Thanks and Regards,
