Could you please describe this more in more detail? Javascript runs on your client, not on your server. You can use the Javascript to get validation from the server though.

Without your code, we can not help you.

well the code is very long but the main logic is on client click event i check some validation and set flag variable. and now if the flag is true i return true which will execute the server side button click event. now after adding the jquery ajax post method inside the compare date function even though my function return true my server side button click event not firing.

Once again, if you want us to help you fix an error or bug, we first need to see your code.

Try adding __doPostBack('btnSave', 'btnSave_Click'); at the end of function CompareDate().

This will trigger a postback on the page executing the server side code on the button_click event

nop this was not worked. this code was always there but the main issue was the post method of jquery ajax. i have used the callback function and it started working.

Is this issue fixed? and you can validate the page inside the compareDate function. Even if you return true the Page_ClientValidate();will not let u to perform the postback until/unless the page.isvalid becomes true.

Hi, thanks for your info. yeah i got my issue fixed by putting async : false in my ajax jquery function. it was now do not allow any background code to run until my ajax request complete.
