    May be doing this wrong
    but i assume the purpose of exposing the datafield is being able to replace with a more appropiate or complex type
    unfortunately it seems to loose its binding and dataannotations (label and description)

    Private Sub dfRangeSelector_AutoGeneratingField(ByVal sender As Object, ByVal e As Telerik.Windows.Controls.Data.DataForm.AutoGeneratingFieldEventArgs) Handles dfRangeSelector.AutoGeneratingField
        Select Case e.PropertyName
            Case "StartDate"
                e.DataField = New Telerik.Windows.Controls.DataFormComboBoxField
        End Select

    thanks

    Hi David,

    I am attaching a small sample which I believe does what you are trying to achieve (placing a combo box field ) .

    Thanks pavel for the sample

    I ended up doing a similar thing

    Instead i replaced the content member of the existing datafield with a combobox

    It there any advantage in replacing the datafield
    with the DataFormComboBoxField as opposed to setting the content property
    Is it considered better "Form"

    just wondering
    dco

    Hi David Ocasio,

    Both approaches are good.  Indeed we allow direct setting/replacing the content for more flexibility. However letting the field to initialize its content generally is better as all neccessary bindings, initialization etc. are done automatically .

    Best wishes,
