Shh... IT in progress.

My XtraLookupEdit, allows you to bind a DisplayValue and EditValue

The title might not seem to make sense so I will hopefully describe it better here.

I have a scenario where in my application the User has security restrictions, these restrictions include limiting the list of users they can assign to a record.

This is where the normal LookupEdit has it’s limitations, you can bind the EditValue but if the Lookup list doesn’t contain a record that is currently assigned it gives a blank/null display.

I was going to put a Suggestion/Question in over at the Support Center but I figured I should see what I could do first.

So I created a simple inherited LookupEdit control, I then added my DisplayValue property which would hold the value I want displayed regardless of the EditValue, next was easy to accomplish by just handling the CustomDisplayText event and violla, I bind the ID to the EditValue and the Display property to the DisplayValue.

Public Class XtraLookupEdit

    Inherits DevExpress.XtraEditors.LookUpEdit

 

    Private _displayValue As String

    <System.ComponentModel.Bindable(True)> _

    Public Property DisplayValue() As String

        Get

            Return _displayValue

        End Get

        Set(ByVal Value As String)

            _displayValue = Value

        End Set

    End Property

 

    Public Sub DisplayText(ByVal sender As Object, ByVal e As DevExpress.XtraEditors.Controls.CustomDisplayTextEventArgs) Handles Me.CustomDisplayText

        e.DisplayText = DisplayValue

    End Sub

End Class

When I get some more time I will ellaborate more in how this is used however if you have any questions in the mean time don’t hesitate to ask.
