Question

I’m having trouble with setting the visibility of a tab when a file is loaded in my application.
When a user launches the app it displays the welcome tab, what I’m trying to do is when a user selects file -> open it loads the file in a new editor form fine but I can’t seem to figure out how to make it load the form and also set the visibility of the editor tab.

          if (this.openEditorDialog.ShowDialog(this) == DialogResult.OK && editForm != null)
        {
            editForm.Close();
            editForm = new EditorForm(this);
            editForm.OpenFile(this.openEditorDialog.FileName);
            editForm.Closing += new CancelEventHandler(EditorForm_Closing);
            editForm.Show();
        }

I’ve tried doing editForm.EditorTab.Show(); as well as Activecontrol = editForm.EditorTab to no avail. Many thanks in advance.

The TabControl has a SelectedTab property: check MSDN for that. I know I have a sample, just need to find it.

…oops, it is SelectTab: here on MSDN

void SetVisibleTab(TabPage tabPage) {
   myTabControl.SelectTab(tabPage);
}
