Set date back to null
posted

I have a grid with a date that is nullable but when I set the date and then want to clear it, it will not let me set it back to null.   How can I do this?

I am using Entity Framework for my data

    To enable a Infragistics grid date column to allow null value, try the following steps:

    1) In your business object class (a bindable data source that binds to the grid), create a property using the nullable date type:

        Public Property YourOptionalDate() As Nullable(Of Date)

    2) Then set these Infragistics Grid settings:

        Me.UltraGrid1.DisplayLayout.Bands(0).Columns("YourOptionalDate").Style = Infragistics.Win.UltraWinGrid.ColumnStyle.Date
        Me.UltraGrid1.DisplayLayout.Bands(0).Columns("YourOptionalDate").ButtonDisplayStyle = Infragistics.Win.UltraWinGrid.ButtonDisplayStyle.OnMouseEnter
        Me.UltraGrid1.DisplayLayout.Bands(0).Columns("YourOptionalDate").Nullable = Infragistics.Win.UltraWinGrid.Nullable.Nothing

    Then you will get a grid with a optional date column that correctly displays null. Hope it helps.
