'Declaration Public Overridable ReadOnly Property CanDelete As Boolean 'Usage Dim instance As DataSourceView Dim value As Boolean value = instance.CanDelete
Property ValueType: System.Boolean
true if the operation is supported; otherwise, false. The base class implementation returns false.
The property reflects not only a capability of the data source control, but also whether it is currently appropriate to perform an operation. For example, even though a data source view supports the ExecuteDelete operation in general, if a required property or some other data is not set, the property returns false, as a delete operation would fail.
The following code example demonstrates how to override the property and the ExecuteDelete method in a class that extends the DataSourceView class. This code example is part of a larger example provided for the DataSourceView class.
' The CsvDataSourceView does not currently ' permit deletion. You can modify or extend ' this sample to do so. Public Overrides ReadOnly Property CanDelete() As Boolean Get Return False End Get End Property Protected Overrides Function ExecuteDelete(keys As IDictionary, values As IDictionary) As Integer Throw New NotSupportedException() End Function 'ExecuteDelete
