    Hello,

    I get this error when switch in edit mode for my grid.
    The column causing this is a GridDateTimeColumn which has display='false' in grid declaration.
    And it displays correctly when in non edit mode.
    ??

    Last RadControls version, IE7.
    Seems a bug ?

    Hi Christian,

    I suspect that the error stems from the fact that the default MinValue setting for date picker in the GridDateTimeColumn is equal to SQL smalldatetime min value. Does changing the min value for the date picker editor programmatically inside the ItemCreated handler of the grid as follows:

    private void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)  
    {  
     if(e.Item is GridEditableItem && e.Item.IsInEditMode)  
     {  
       ((e.Item as GridEditableItem)["<My_DateTimeColumn_UniqueName>"].Controls[0] as RadDatePicker).MinDate = "01/01/1700";  
     }   

    addresses the error in question? Let us know whether this helps.

    Kind regards,
