Gets a value indicating whether the DataSourceView object associated with the current DataSourceControl object supports the ExecuteInsert(IDictionary) operation.

public:
 virtual property bool CanInsert { bool get(); };

public virtual bool CanInsert { get; }

member this.CanInsert : bool

Public Overridable ReadOnly Property CanInsert As Boolean

Property Value

Boolean

true if the operation is supported; otherwise, false. The base class implementation returns false.

Examples

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.
public override bool CanInsert {
    get {
        return false;
    }
}
protected override int ExecuteInsert(IDictionary values)
{
    throw new NotSupportedException();
}

' The CsvDataSourceView does not currently
' permit insertion of a new record. You can
' modify or extend this sample to do so.
Public Overrides ReadOnly Property CanInsert() As Boolean
   Get
      Return False
   End Get
End Property

Protected Overrides Function ExecuteInsert(values As IDictionary) As Integer
   Throw New NotSupportedException()
End Function 'ExecuteInsert

Remarks

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.
