Question

Answer 1

I had a user control within another user control. textbox1.Select() worked for me but textbox1.Focus() did not work.

You can also try setting Tabstop to false, textbox1.Focus(), TabStop true.

Answer 2

The following is the solution:

private void frmMainLoad(object sender, EventArgs e)
{
    ActiveControl = textBox1;
}

The better question would however be why... I'm not entirely sure what the answer to that one is.

Edit: I suspect it is something to do with the fact that both the form, and the TabControl are containers, but I'm not sure.

Answer 3

  private void ChildForm1_Load(object sender, EventArgs e)
        {
            ActiveControl = txt_fname;

        }

Answer 4

Try putting it in the Form_Shown() event. Because it's in a container, putting in the Form_Load or even the Form() constructor won't work.

Answer 5

Try to use textbox1.Select() instead of textbox1.Focus(). This helped me few times.

Answer 6

You just need to add the Control.Select() for your control to this code. I have used this to set focus on controls during validation when there are errors.

private void ShowControlTab(Control ControlToShow)
    {
        if (!TabSelected)
        {
            if (ControlToShow.Parent != null)
            {
                if (ControlToShow.Parent.GetType() == typeof(TabPage))
                {
                    TabPage Tab = (TabPage)ControlToShow.Parent;
                    if (WOTabs.TabPages.Contains(Tab))
                    {
                        WOTabs.SelectedTab = Tab;
                        TabSelected = true;
                        return;
                    }
                }

                ShowControlTab(ControlToShow.Parent);
            }
        }
    }
