    Unsupported control type in DataGrid column

    Hello again,
     
    I'm receiving the following error when I attempt to update an entry from a datagrid (developed in Dreamweaver MX 2004):
     
    System.Exception: Unsupported control type in DataGrid column: CuteEditor.Editor
    at DreamweaverCtrls.DataSet.OnDataGridUpdate(Object Src, DataGridCommandEventArgs E)
     
    Any thoughts/comments/suggestions would be greatly appreciated!  If you can solve the problem I'll give you a cookie!

    Re: Unsupported control type in DataGrid column

    George,
     
    where did you implement the following methods:
     
    OnUpdateCommand="ds_common_sense_edit.OnDataGridUpdate"
    OnEditCommand="ds_common_sense_edit.OnDataGridEdit
    OnPageIndexChanged="ds_common_sense_edit.OnDataGridPageIndexChanged" OnCancelCommand="ds_common_sense_edit.OnDataGridCancel" OnItemDataBound="ds_common_sense_edit.OnDataGridItemDataBound"
     
    I can't find them in your page.

    Re: Unsupported control type in DataGrid column

    it is on the same line as some other code:
     
      ShowHeader="true" OnUpdateCommand="ds_common_sense_edit.OnDataGridUpdate" OnEditCommand="ds_common_sense_edit.OnDataGridEdit"
      OnPageIndexChanged="ds_common_sense_edit.OnDataGridPageIndexChanged" OnCancelCommand="ds_common_sense_edit.OnDataGridCancel" OnItemDataBound="ds_common_sense_edit.OnDataGridItemDataBound"
     
     
    Thanks for the speedy reply!
