LinqDataSourceDeleteEventArgs.OriginalObject Property

Definition

Gets the object that represents the data to delete.

public:
 property System::Object ^ OriginalObject { System::Object ^ get(); };
public object OriginalObject { get; }
member this.OriginalObject : obj
Public ReadOnly Property OriginalObject As Object

Property Value

An object of the type specified in the TableName property that contains the data to delete.

Examples

The following example shows how to cancel the delete operation based on a property in the OriginalObject property and a value from the Web page. In the example, users must select a CheckBox control to confirm that they want to delete a product record when its OnSale property is set to true.

protected void LinqDataSource_Deleting(object sender, LinqDataSourceDeleteEventArgs e)
{
    Product product = (Product)e.OriginalObject;
    if (product.OnSale && !confirmCheckBox.Checked)
    {
        e.Cancel = true;
    }
}
Protected Sub LinqDataSource_Deleting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.LinqDataSourceDeleteEventArgs)
    Dim product As Product
    product = CType(e.OriginalObject, Product)

    If (product.OnSale And Not confirmCheckBox.Checked) Then
        e.Cancel = True
    End If
End Sub

Remarks

You can use the OriginalObject property to interact with the data before it is deleted. You can validate the data, or you can cancel the event by setting the Cancel property to true. You can modify which record is deleted by changing the value or values of the object in the OriginalObject property.
