    Hi there,

    just got reported by our user that the RadComboBox is somehow not working correctly. Here are the steps:

    01. type a for search, and there will be items listed => select one of them => eveything seems ok and works fine.

    02. click the ComboBox, all text are automatically selected => works as expected

    03. start to type something, e.g. b => now weird thing happens, a list of items are expected to shown, but it stucks at loading, if you look at the client requests in your browser debugging tool, you will notice that the client keeps sending requests to the server side with weird search string from the previous select. ==> a BUG? or did I make anything wrong.

    This is a Production Issue, hope you guys can guide me out how to fix it.

    PS. i tried to upload a small demo application to reproduce the error, but i don't how to upload it, seems I cannot upload a zip file!


    Regards

    Z. Wang

    Hello,

    You're not allowed to zip files when you write a forum post. You need to open a support ticket in order to send a demo application.

    The problem is caused by the AutoPostBack property of the ComboBox which is set to true. When using the load on demand functionality the ComboBox items are not accessible on the server-side. Having AutoPostBack="False" will fix the issue.

    And last, but not least, I would ask you avoiding threads duplication for an issue, which allows us to provide you with better support. Since you've opened a support ticket I would suggest you to continue our conversation there, if you have any further questions.

    Regards,

    Hello Thomas,

    The problem in this concrete scenario was when using the load on demand functionality the ComboBox items are not accessible on the server-side as I pointed out in my last post.
    If that's not your case I would suggest you to open a support ticket and elaborate more on your issue.
