How can I to remove or reset the tab order in VS 2010

Those numbers are the order that your controls will be hit when pressing the 'Tab' key. When in View Tab Order mode, you can click on the controls in the order that you want them to be hit. That will re-order them. You'll notice that the numbers start changing as you click.

Here's the MSDN page on how to do Tab Order.

None of the provided answers really satisfied me. With the accepted one, you still have to go through each control...

Here's what I did:

• Open the [Form].Designer file.
• Quick replace with regular expressions: .TabIndex = {.+}, replace with: .TabIndex = 99 or whatever highest number you want (or even zero (0)).

• THEN go to design view and set the order via Tab Order command
