<BR><BR>/JanDYou can also just make the set the type=reset property on the button and it will automatically clear all the fields for you.<BR><BR>This way you don't have to do any coding....<BR><BR>I've a reset button, but it never clears the text of any of my server controls. All these server controls have their viewstate set to true. So, when i click on reset button, it wouldn't clear any of them. Any suggestions, please do advice.The reset button resets the values of the html elements back to the value specified in the "value" attribute of the html tag. In a post back situation, the HTML page gets reloaded and the "value" attribute in the html tags of those input fields are set to their corresponding values in view state... So, I think the only way to get around this is to avoid any post back in the form. Otherwise, looks like you will have to set everything manually back to the original value, which is not that difficult if you simply loop through all the elements in the Controls collection.
