DataSourceView::CanUpdate Property

Gets a value indicating whether the DataSourceView object associated with the current DataSourceControl object supports the ExecuteUpdate operation.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)

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

Property Value

Type: System::Boolean
true if the operation is supported; otherwise, false. The default implementation returns false.

The CanUpdate 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-bound control supports the ExecuteUpdate operation, if a required update command or some other data is not set, the CanUpdate property returns false, as an update operation would fail.

The following code example demonstrates how to override the CanUpdate property and the ExecuteUpdate method in a class that extends the DataSourceView class. This code example is part of a larger example provided for the DataSourceView class.

No code example is currently available or this language may not be supported.
