Focus onload not working properly

Question

I'm working with a windows application.(.net/c#) on load I want to make first/default control as selected and start dataEntry without using mouse.

After I add this.ActiveControl = myTextbox; OR myTextbox .Select();It would work fine looking on UI

but the same is not active or typable without using mouse initially. I tried the same for Company combobox also and not working expected manner.

I Tried with Focus() as well.

Code:

protected override void OnLoad(EventArgs e) 
{ 
    base.OnLoad(e);
    _context = new CompanyContext();
    companyList = _context.Companies.ToList();
    var companylist = new BindingList<BPS.Data.Entities.Company>(companyList);
    metroComp.DataSource = companylist;
    metroComp.DisplayMember = "CompanyName";
    metroComp.ValueMember = "CompanyName";
    this.ActiveControl = myTextBox;
    //myTextBox.Select();// Tried this line also and working same effect
}

I tried that code in Form_Load also

Maybe show us some of your code... we can see what you are doing wrong then — kevintjuh93, Oct 15 '15 at 11:29
Be careful with `OnLoad`, you may have an [exception in there that's not being caught](http://stackoverflow.com/questions/4933958/vs2010-does-not-show-unhandled-exception-message-in-a-winforms-application-on-a). — bokibeg, Oct 15 '15 at 11:37
long code in comment is too difficult to read. moved code to question. — bansi, Oct 15 '15 at 11:38
agree with @bokibeg. try `this.Activate()` also your form may not be the active parent control. — bansi, Oct 15 '15 at 11:42
@b_in_u Just use the `Shown` event instead and put `myTextBox.Focus()` inside it. That's the classic way of doing it. You can override `OnShown` if you want for the same effect. — bokibeg, Oct 15 '15 at 11:45
would calling base.OnLoad(e) at the end make any difference (or work at all)? — apokryfos, Oct 15 '15 at 11:48
can you please try by adding this two lines in your code, InitializeComponent(); myTextBox.Focus(); — Pedram, Oct 15 '15 at 11:50
@rajeshmpanchal . this is also working and nice solution too Thanks!! — b_in_U, Oct 15 '15 at 11:53

Also add below line of code,

this.Activate();

To your form. It may not be the active parent control. when the form is shown.

I would suggest to activate the form at the end of the Load event. so the form becomes the active form in the application.

So I think this is working code for your case,

protected override void OnLoad(EventArgs e)
        {
            base.OnLoad(e);
            _context = new CompanyContext();
            companyList = _context.Companies.ToList();
            var companylist = new BindingList<BPS.Data.Entities.Company>(companyList);
            metroComp.DataSource = companylist;
            metroComp.DisplayMember = "CompanyName";
            metroComp.ValueMember = "CompanyName";
            InitializeComponent();
            myTextBox.Focus();
        }
