How to Lock the User Entry while Web Service is Running?

[varunkumarid]

Hi to all,

I have a Web Service to Check the User Name is Already Exists or Not.

I have called the Web Service In .cs(Code Behind) file like Following.

 txtUserName.Attributes.Add("onChange","return CheckUserNameAvailability()"); 

if Suppose the user enter the name and suddenly click the save button the onChange event wont perform Suddenly before the control is going to server, so it saved and then the onchange event called.

i check the status value that is return by webservice method. but the method called after control is going to server and then the onchange event is performed.

How can i solve this problem?

Is there any other way to do this?

Thanks to all

Perhaps you should try disabling the "save" button for the time the nickname is being checked. But it's hard to say anything without seeing much code.
