    Hi

    In our Silverlight 4 (using ria services) we use the latest version of the rad Gridview control. We allow the columns order to be changed. The grid(s) in our application normally have many columns (50 and more). In previous versions, when changing the column order, it was possible, to scroll horizontally, so it was possible, to move the first column to the end of the grid in one step. In the current version, scrolling is not possible when moving a column which makes it rather cumbersome to change the column order when there are many columns.

    My questions are:

    - Is there a workaround for the current version to reenable the feature?
    - Will the behaviour be changed/fixed in future releases?

    Greetings and thanks in advance.

    Hello Ashwini,

     Since, Q2 2011 we have made some changes in DnD logic and introduced alternative API close the build-in framework one - http://www.telerik.com/help/silverlight/dragdropmanager-events.html. However, we have left two options to support AutoScroll:

     - Switch to legacy execution mode - http://www.telerik.com/help/silverlight/raddragdropmanager-howto-change-drag-execution-mode.html

     - use AutoScrollBehaiour as the one demonstrated in the project attached.

    Hi

    Just to inform you. I managed to make it work with the legacy-mode. Thanks for your help. (I tried the behaviour stuff as well but it didn't get it working. However, I did investigate any further as I have found a solution).

    Greetings

    Hi

    There seem to be sideeffects when I switch to legacy mode. (nullpointer exceptions when increasing the size of a column) So i had to turn it of.  But the solution with the behaviour seems to work.. Thanks
