    Hello Allen,

    You need to set the IsDropDownOpen property.

    All the best,

    I have a radGrid control inside a radCombobox control. When I try to sort the items in the radGrid by clicking on the grid column header, the RadGrid NeedDataSource event gets called and the radCombobox collapses. I want the radCombobox dropdown to stay open so that the user can pick the rows from the radGrid after sorting. Can someone assist me in what needs to be done to keep the
    radComboxbox open after sorting the datagrid?

    Thanks in advance.

    It is possible do it using method showDropDown, such like this:

    var combo = $find("<%= rcbDistricts.ClientID %>");

    Add this to your RadComboBox:

    OnClientKeyPressing="(function(sender, e){ if (!sender.get_dropDownVisible()) sender.showDropDown(); })"
