The Microsoft® Windows Forms DataGridView control in Microsoft® Visual Studio® 2005 provides a grid experience similar to Microsoft® Excel, but does not provide the column filtering drop-down lists that Excel provides in its AutoFilter feature. However, the DataGridView can bind to data sources that provide filtering, such as the ADO.NET DataView. This article describes how to build a custom DataGridView column header cell that displays drop-down filter lists, by taking advantage of the filtering capabilities of the data source and the new BindingSource component.
