Hi, If the Textbox value is empty then, when i click "Ok" button an alert should display as "Please Enter the value for textbox" and simultaneously i have to display an "*"(Asteristic) only if the textbox is empty. Otherwise don't display. Please help me.. if(document.getElementById('txtbox').value=="") { alert('Enter text value'); return false; } -------

So what's the problem here ? Why don't you use validation control ?

yes here i used validation as below you see if(document.getElementById('txtvalue').value=="") { alert('Entertext value'); document.getElementById('Asteristic').style.display="inline"; return false; } but it says "Object required". How can i display the "*"(label control) only if the textbox is null?

Your textbox id is txtTickInfo, not txtbox.

I guess your textbox name is txtTickInfo. Check that
