ListControlDesigner::OnDataSourceChanged Method

Called when the data source for the associated control has changed.

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

public:
virtual void OnDataSourceChanged()

The OnDataSourceChanged base method connects the associated control that is derived from the ListControl object to the current data source and, if that is different from the data source to which the control was connected, updates the design-time markup. The OnDataSourceChanged method updates the design-time markup after connecting to the current data source.

The following code example overrides the OnDataSourceChanged method in a class that inherits from the ListControlDesigner class. When the data source that is associated with the designer class changes, the OnDataSourceChanged method is called and this code sets a variable named changedDataSource to true.

This code example is part of a larger example provided for the ListControlDesigner class.

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