    I have a fixed position div that is always at the bottom of my page.  Inside that is a RadComboBox with around 30 items.  Sometimes it expands upwards, sometimes it expands downwards and so out of view and unusable. 

    How can I force the RadComboBox to always expand upwards?

    Thanks.

    Hello Craig,


    Set the EnableScreenBoundaryDetection property of RadComboBox to "True" which in turn opens the dropdown based on screen Boundaries.

    Hi Shinu,

    I have now added the property but it does not work for me.  The combobox now alternates between expanding up or down with each click - 1st click down, 2nd click up, 3rd click down, 4th click up and so on.  It may have already being doing this and I had not noticed.

    Hi Craig Wallace,

    This may be an issue in the screen boundary detection.

    Can you share here the minimum layout of the page that triggers the issue?

    Hi Simon,

    I have tried a few resolutions and they all exhibit the same behaviour.  Even 800x600 and lower does it.

    Hello simon torrance,

    Please excuse me for not being clear enough in my previous post.

    I meant that you send me the minimum HTML required to trigger the issue as we will need to first reproduce it and confirm it is a bug before actually proceed with the fix. If it will be more convenient for you, you can send us a runnable project via a support ticket.

    Thank you in advance for your assistance.
