How to call server side button event from javascript function in asp.net?

Question

while trying to call a server side button event from javascript function my code looks like this

 _doPostBack('CalendarButton','CalendarButton_Click');

where CalendarButton is my buttonname and 'CalendarButton_Click' is my CalendarButtonevent

But this statement is not working. I know there is some minor error but i can't find what it is.

Answer 1

You have one _ it has two

__doPostBack

Answer 2

You do not have to pass in the second argument to __doPostBack(). Just __doPostBack('CalendarButton', '').

Alternatively you can call click() on the button itself. document.getElementById("CalendarButton").click();.
