>Can anyone please tell me how I can move from one tab to another at design time?? Cause I can only design Tab1 ... How can I activate tab 2 etc... ??

Which tab control are you using (2 comes with VB - TabStrip and SSTab)?

With TabStrip, you need to put the contents of your different tabs into different containers (like frame) and play with their Visible property at run-time.

With SSTab, you only need to click on the desired tab and nothing to do in the code.
