Your question and your code sample do not match - are you trying to set the focus or the TabIndex property?

Still no match with your code sample -- there is no "itemname". Not to worry, you got a general answer.

A short note to the correct answer by Mario, just to close the topic: all controls are always created and added dynamically. If you think the Designer does something different, think again. The designer only helps you to create the code during design-time. What happens during runtime is exactly what you do in your application. Look at the C# code auto-generated by the Designer to see it.

Solution 1

Once added the control to the panel1, try calling the Focus method.

txtsrno.Focus();

Should help!

Cheers!
