TreeView not expanding in some browsers

[matt vaughn]

I have been researching something similiar to this for applications using the new Callback. There are (2) JavaScript methods that used by this mechanism and really handled by the WebResources.axd handler.

In my case I get WebForm_InitCallback() and WebForm_DoCallback() - - > "Object expected" errors.

The only way I get it to work is to:
1. go to the IIS console
2. right-click the site and select Properties
3. Click on the "Configuration" button
4. Select the .axd Extension and click Edit
5. Uncheck the box "Check that file exists".

In addition:
1. restart IIS
2. dump any Temporay Internet files from the browser Tools | Options
3. I even clear the Tempary ASP.Net files from the Framework directories.

I report some usefull informations due to the old date of this thread.

I'm talking about TreeView Web Control in ASP.NET 2.0.
The error in object occurs when a user with IE5.5 SP2 click on the + near a
TreeNode: the node does not expand itself and the browser raise the
following client script error "The download of the specified resource has
failed". In IE6 all works well".

Thanks again.

In Visual Studio 2010 using IE 7 I get this error almost everytime there is a corp wide security update. Also an error on the web.config <pages maintainScrollPositionOnPostback="true"> setting. I have found that everytime I simply empty the IE7 Temporary Internet Files, these js errors are gone.

No need to follow IIS instructions when in Debug in VS.

dump any Temporay Internet files from the browser Tools | Options
