It seems you are using Validation controls in your page. Your page must pass the validation before postback to server. Below is the functionality of CausesValidation property:

• The CausesValidation property specifies if a page is validated when a Button control is clicked.

• Page validation is performed when a button is clicked by default.

• This property is mostly used to prevent validation when a cancel or reset button is clicked.
