Hi,

I have a basic question. I have a form with a textbox and check box and a datagrid and save button. After entering the text in text box and checking the check box and clicking the save button contents are added to grid. And my contents in the text box and check box are not cleared off.

I think this is something to do with view state and post backs.

what is the efficient way to clear off all my controls content after post back.

Thanks in advance.

One of the differences between html control and web control is that html control can clear after posting back, but web control can't.
If you view the source of page, you will see the code like following example whose function is to save the web control info and display it after posting back.

<input type="hidden" name="__VIEWSTATE" value="dDwxNzY3ODc4MzI4OztsPE1vZHVsZUJhbm7Pj7sbd7l pUK5F1n7oFJus5Ob4uBEvw==" />

In my opinion, you need to clear all of the web controls by yourself.
