Hi,

When you say "update the text box", do you mean you type something in the textbox and then tab out? If that triggers a postback, you will want to check the textbox's AutoPostBack property. This property itself should have nothing to do with our controls.

If AutoPostBack is set to false and the page still posts back, you will want to find out the triggering point through trial and error: gradually remove other controls (or set other controls' Visible to false) and see when the problem stops occurring. Once you know what triggered it, it should not be very difficult to find out the root cause fix/workaround it.

TabStrip does not cause a postback unless its RaisesServerEvent is set to true.

Thanks

I see. When you click a button the page supposes to postback, so there is nothing wrong there. You can however use the CallbackPanel to avoid a postback. You will need to place whatever you want to update inside the CallbackPanel and also set the CallbackPanel's Triggers --- this is probably what you have missed. You can find more information on how to use the CallbackPanel at here:

CallbackPanel is also used extensively in our sample project. So you can take a look of that. If you have not played with the CallbackPanel before, I would suggest you to try it out in a separate page first, that way you can see how the CallbackPanel works much quicker without worrying about something else in your page is wrong.

Thanks

That would be up to you. Technically there is no difference from our side. It's like choosing between an 8 seats van for the family or two separate cars, it all depends on how often you update them and how often you update them together.
