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 tabOrder of 0   If I want to achieve the same result at run-time  using code  how should I proceed  Are there alternatives to using tabOrder  I assume any run-time code will be in the form s constructor or its onload event handler     EDIT In other words I d like to be able to type straight into the textbox as soon as the form appears without having to manually tab to it  or manually select it

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

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

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
