How to: Access Keyed Collections in Windows Forms

The key associated with an item in a collection is typically the name of the item. The following procedures show you how to use collection classes to perform common tasks.

To find and give focus to a nested control in a control collection

  • Use the Find and Focus methods to specify the name of the control to find and give focus to.

    
    Dim OrderForm1 As New OrderForm()
    OrderForm1.Show()
    OrderForm1.Controls.Find("textBox1", True)(0).Focus()
    
    
    

To access an image in an image collection

  • Use the Item property to specify the name of the image you want to access.

    
    Me.BackgroundImage = imageList1.Images("logo.gif")
    
    
    

To set a tab page as the selected tab

  • Use the SelectedTab property together with the Item property to specify the name of the tab page to set as the selected tab.

    
    tabControl1.SelectedTab = tabControl1.TabPages("shippingOptions")
