Example

In the following example, a LookUpEdit control is bound to the Categories table, which contains the CategoryID, CategoryName, Description and Picture fields. The control displays data from the first three fields. When you select a new record in the LookUpEditor (the control’s BaseEdit.EditValueChanged event), a separate PictureEdit control displays this record’s Picture field value.

C#

private void simpleButton1_Click(object sender, EventArgs e) {
    // Select a record in the LookUpEdit control
    lookUpEdit1.EditValue = lookUpEdit1.Properties.GetKeyValueByDisplayValue("Condiments");
}

private void lookUpEdit1_EditValueChanged(object sender, EventArgs e) {
    LookUpEdit lookUp = sender as LookUpEdit;
    // Access the currently selected data row
    DataRowView dataRow = lookUp.GetSelectedDataRow() as DataRowView;
    // Assign the row's Picture field value to the PictureEdit control
    if (dataRow != null) {
        ImageConverter imConverter = new ImageConverter();
        pictureEdit1.Image = (Bitmap)imConverter.ConvertFrom(dataRow["Picture"]);
    }
}

VB.NET

Private Sub SimpleButton1_Click(sender As Object, e As EventArgs) Handles SimpleButton1.Click
    ' Select a record in the LookUpEdit control
    LookUpEdit1.EditValue = LookUpEdit1.Properties.GetKeyValueByDisplayValue("Condiments")

End Sub

Private Sub LookUpEdit1_EditValueChanged(sender As Object, e As EventArgs) Handles LookUpEdit1.EditValueChanged
    Dim Lookup As LookUpEdit = CType(sender, LookUpEdit)
    ' Access the currently selected data row
    Dim DataRow As DataRowView = CType(Lookup.GetSelectedDataRow(), DataRowView)
    ' Assign the row's Picture field value to the PictureEdit control
    If Not DataRow Is Nothing Then
        Dim imConverter As ImageConverter = New ImageConverter()
        PictureEdit1.Image = CType(imConverter.ConvertFrom(DataRow("Picture")), Bitmap)
    End If
End Sub
