Problem with Validation Controls

Hi every body,

I have a Web page with 3 Text Boxes and 3 Validation controls(all are Regular expression Validators only with runat= server attribute ) and a Submit Button.The condition is any one of the Text Box should be filled with the appropriate Data, if all the text boxes are free or the data entered in any one text box is not correct then validation should be taken place by clicking on submit button with out going to Server.

if any body help me in this..............

Thanks in advance
