Will calling .click() fire an updatepanel Trigger?

This might seem a bit silly but...

Basically, I have a javascript function which calls the .click() method of a button, this button resides outside of any UpdatePanels

This button is also set as a trigger for one of my UpdatePanel controls.

My problem is, the button click runs fine, the server side click event fires ok and rebinds some data for a GridView which is inside the UpdatePanel, but the UpdatePanel does not update its contents.

Do you have to physically click the button with your mouse to cause the Trigger? Or should the programmatic javascript call to click() work?

No will not cause it trigger, you need a postback for that, not a javascript call


You cantrigger an UpdatePanel refresh from the client side, using __doPostBack().

Hi

The programmatic javascript call to click() should work, you must do something wrong.

Look this sample:

Workarounds for AutoCompleteProperties

ASP.NET AJAX 1.0 no longer allow AutoCompleteProperties section. I used to have one AutoComplete Extender maps to 3 controls calling the same WebService. What's the new way to do it in this new build apart from creating more AutoComplete Extenders?

Now you must have 3 AutoCompleteExtenders because extenders now maps to their target control directly. All this extenders can use the same web service.

Hope, this helps.
