Examples
The following example shows an event handler for the Updating event. The example shows how to compare properties from the OriginalObject property and the NewObject property to determine whether the value in the Category property has changed. If so, the CategoryChanged property of the object in the NewObject property is set to true.
protected void LinqDataSource_Updating(object sender, LinqDataSourceUpdateEventArgs e)
{
Product originalProduct = (Product)e.OriginalObject;
Product newProduct = (Product)e.NewObject;
if (originalProduct.Category != newProduct.Category)
{
newProduct.CategoryChanged = true;
}
}
Protected Sub LinqDataSource_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.LinqDataSourceUpdateEventArgs)
Dim originalProduct As Product
Dim newProduct As Product
originalProduct = CType(e.OriginalObject, Product)
newProduct = CType(e.NewObject, Product)
If (originalProduct.Category <> newProduct.Category) Then
newProduct.CategoryChanged = True
End If
End Sub
Remarks
Create an event handler for the Updating event and retrieve the NewObject property to validate the data. You can also change the data or cancel the update operation.
