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

public override IEnumerable GetDesignTimeData (
	int minimumRows,
	out bool isSampleData
public IEnumerable GetDesignTimeData (
	int minimumRows, 
	/** @attribute OutAttribute() */ /** @ref */ boolean isSampleData
Not applicable.



An integer containing the minimum number of rows to retrieve.


A value indicating whether the data returned is sample data or real data.

Return Value

A sample of the data represented by the associated ObjectDataSource or a null reference (Nothing in Visual Basic) if the designer cannot generate any sample data.

The GetDesignTimeData method provides a design-time version of the ObjectDataSource view for use by the associated data-bound control designer.

It is not expected that the designer will perform actual data access at design-time time. Instead, the designer creates sample data that matches the schema of the data source.
