Use RequiredFieldValidator. Add a RequiredFieldValidator and set the property ControlTovalidate as your textboxname , set the appropriate error message on ErrorMessage property

no i cannot use requiredfieldvalidator . I want to have clint side interaction;requiredfieldvalidator works on server side .Something in javascripting ?????????
No buddy. It works in client side. Anyway the javascript code for mandatory text field is here function RequiredField() { document.getElementById("lblErrormessage").innerText = ''; if(document.getElementById("TextBox1").value == '') { document.getElementById("lblErrormessage").innerText = "Field is required"; return false; } return true; } add this method in Page_Load event code bahind on some submit button onclick like button1.Attributes.Add("onclick","return RequiredField()");

Of course, "Textbox1" won't work, as the framework assigns it's own Id, based on where the control is in the page heirarchy. You're definately better off using the validators, which do indeed work on the client.

why are you changing your code yourself. see my code for text box as if(document.getElementById("TextBox1").value == '') but you changed as innerText. for textbox its value for label its innerText ok
