Teroid Data Filter 3.0 is a .NET Windows Forms control allowing users to specify filtering criteria in applications using an ADO .NET DataView or BindingSource as a data source. It can be used on a form containing data-bound controls or a DataGridView, or on a separate dialog box. After the DataView or BindingSource properties are set, a row is added to the control for each column in the underlying data source, each containing controls allowing the user to set the criteria condition (=, >, LIKE etc) and a criteria value. These selections are then used to create a filter string for use as the DataView's RowFilter property or the BindingSource's Filter property. The control has methods to apply the filter to the data source or clear any user criteria, and can optionally show buttons to allow the user to utilize this functionality directly.
