IE9 & Tessitura web custom screens

Jon Ballinger
$organization

Hello,

I have updated to IE9 and I have noticed that our web custom screens that use the ASP.Net Ajax UpdatePanel with a dropdown box stop fucntioning properly in tessitura.  The dropdown box  can have a value selected, but it does not retain the value after selection.  These screens are still functioning on all other computers with IE8. 

I thought I would ask to see if anyone else encountered this before I go forward with changing the screens so they do not use the UpdatePanel.

Thanks in Advance,

Jon

    Jon,

     

    Is selecting an item from the causing a partial postback? I had issues with this where the my control was coming back as undefined during the partial postback. You can tell by running a trace on the page and looking at the forms collection section and looking at the value of the control. If it is working, the value will be the "Selected Value" if it is not working, the value will be "Undefined".

    Hi Marty,

    Thanks,  I did try that it does not seem to work for me in IE9.  I am gong to keep looking around on the net and see if I can find something. I am hoping not to rewrite them.

    Jon,

     

    Try this,

    One thing to note, is that once I did this, some of my list boxes stopped working so I had to change to different controls to replace the list boxes.

    Marty,

    I am using an asp:DropDownList, and having it postback on the SelectedChange event.   The control is also set to autopostback.   The error I am getting returned to the client is:

    "Invalid postback or callback argument. Event validation is enabled using <pages enableeventvalidation="true" /> in configuration or <%@ page enableeventvalidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation."

    I am only getting this when the page is run through tessitura otherwise it is fine.  I did try setting enableEventValidation to false.  This does remove the message but the dropdown no longer holds the selected value on postback.  I think when run through tessitura it is not seeing the values as valid ones for the postback when it is checking.
