determine if ajax update is occuring

[Albert Shenker]

I have a two buttons on different pages which perform the same action. In one case, the button is ajaxified and in the other it is not. In the code which handles both button clicks, I need to call some client-side script. If the button is ajaxified, I simply add the script using  ajaxamanager.ResponseScripts.Add. In the nonajaxified scenario, I simply use RegisterScriptManagerScript.

My question is:

is there a way within code to tell if an ajax update is occurring. Like I said, I would like to have one function which handles the button cick in both scenarios. Within this function, I need a way to branch off and call the ajaxmanager code if an ajasupdate is occuring, and the other if it is not.

Hi Albert,

You could handle the OnButtonClick events for the both buttons and use the following to check if the request is ajax request:

if (ScriptManager.GetCurrent(Page).IsInAsyncPostBack)
           {
                   // Do something only when the page is partially posted back
           }

I hope this helps.

Kind regards,
