Setting focus to a textbox control

Question

If I want to set the focus on a textbox when the form is first opened, then at design time, I can set it\'s tabOrder property to 0 and make sure no other form control has a tabO

Answer 1

Because you want to set it when the form loads, you have to first .Show() the form before you can call the .Focus() method. The form cannot take focus in the Load event until you show the form

Private Sub RibbonForm1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    Me.Show()
    TextBox1.Select()
End Sub

Answer 2

I think what you're looking for is:

textBox1.Select();

in the constructor. (This is in C#. Maybe in VB that would be the same but without the semicolon.)

From http://msdn.microsoft.com/en-us/library/system.windows.forms.control.focus.aspx :

Focus is a low-level method intended primarily for custom control authors. Instead, application programmers should use the Select method or the ActiveControl property for child controls, or the Activate method for forms.

Answer 3

Private Sub Form1_Shown(sender As Object, e As EventArgs) Handles Me.Shown
    TextBox1.Select()
End Sub

Answer 4

Quite simple :

For the tab control, you need to handle the _SelectedIndexChanged event:

Private Sub TabControl1_SelectedIndexChanged(sender As Object, e As System.EventArgs) _
  Handles TabControl1.SelectedIndexChanged

If TabControl1.SelectedTab.Name = "TabPage1" Then
    TextBox2.Focus()
End If
If TabControl1.SelectedTab.Name = "TabPage2" Then
    TextBox4.Focus()
End If

Answer 5

create a textbox:

 <TextBox Name="tb">
 ..hello..
</TextBox>

focus() ---> it is used to set input focus to the textbox control

tb.focus()

Answer 6

Using Focus method

  Private Sub frmTest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
       yourControl.Focus()
    End Sub
