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 : boolPublic Overridable ReadOnly Property CanInsert As BooleanProperty Value
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.
