ListControlDesigner.OnDataSourceChanged Method (Boolean)

Note: This method is new in the .NET Framework version 2.0.

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

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

protected override void OnDataSourceChanged (
	bool forceUpdateView
)
protected void OnDataSourceChanged (
	boolean forceUpdateView
)
protected override function OnDataSourceChanged (
	forceUpdateView : boolean
)

Parameters

forceUpdateView

A Boolean that indicates whether the design-time markup is to be unconditionally updated. This parameter is ignored.

The OnDataSourceChanged base method connects the associated control that is derived from the ListControl class 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 of the designer unconditionally updates the design-time markup after connecting to the current data source. The value of forceUpdateView is ignored.

Notes to Callers Callers should use the public OnDataSourceChanged override.

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 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.

// If the data source changes, set a boolean variable.
public override void OnDataSourceChanged()
{
    changedDataSource = true;
} // OnDataSourceChanged
