The function you are calling from your onBlur event is "chk"... Whereas your function name is listed as "check"... That is the only problem I can see. Otherwise this will work properly.

If you just want the ID, the full ID is contained in the textbox properties ClientID; eg:

txtbox1.attributes.add("onBlur", String.Format("check('{0}')", txtbox1.ClientID));

thnx.
but dat is not mistake in function. i've perhaps wrote dis here like dis in short form. when i run the page i am getting error. alert message is not being displayed. i would like to know if there is any other way to do it.

The code is valid as I've tested it myself. Check the HTML and make sure it is adding the correct attributes to the button and calling the right JS function, the JS function is there etc.
