I implemented a simple visual web part with updatepanel with a button and a label. When I click on a button, OnClick event is called and the label is getting filled. This works fine in all browsers except for SAFARI browser. In safari the OnClick event is not getting called at all. I have even implemented this in an application but the result is same in safari browser. A sample asp.net application with the same structure with update panel works in SAFARI too. Only when implemented in sharepoint, the safari browser is not getting partial postback. I have checked that the scriptmanager has enablePartialMethods = true. Let me know if there is any solution for this in SAFARI.
you have two methods! first i would try the following:
if this solution doesnt work than you can try this:
you need to do the following:
create a js file.
goto desktop and create a text file, name it anything like so:
make sure you have the extension .js otherwise its still a text file!
now open the file, dont double click! just right click and open with any text editor like notepad or notepad++
now copy and past this code:
now save and exit! copy the file to a layouts folder under this location:
create a new folder
add the file webkitFix.js to the folder:
now update the webapplication masterpage:
open with notepad or notepad++ (prefered) or sharepoint designer
now add the JS file to load first in masterpage!
I may have a variation on this issue: Like the OP I have a very simple test page with an out of the box master page. A couple of controls in an UpdatePanel including a dropdown list with a SelectedIndexChanged event handler. Only on OSX/Safari do I get full postback on a DDL selection change.
Via JS debugging I discovered a page redirect. Fiddler revealed 401 & 302 status codes. I turned off Form authentication and now the UpdatePanel works.
This is not really an answer in my situation (it appears claim authentication requires Form authentication and I need that in production) but maybe it'll help somebody else.
