'Declaration Public Overridable ReadOnly Property CanInsert As Boolean 'Usage Dim instance As DataSourceView Dim value As Boolean value = instance.CanInsert
Property Valuetrue if the operation is supported; otherwise, false. The base class implementation returns false.
The CanInsert 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 control supports the ExecuteInsert operation, if a required insert command or some other data is not set, the CanInsert property returns false, as an insert operation would fail.
The following code example demonstrates how to override the CanInsert property and the ExecuteInsert 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 insertion of a new record. You can ' modify or extend this sample to do so.
