You can achieve this by implementing the IFilter interface and setting it with the Grid.Filter property . Data filtration implemented via IFilter interface of non-event-driven model consists in the Row.Update() method call . You can try this public class CustomFilter : IFilter { public bool IsFiltered(Row row) { //There are three ways to get cell's value: //1. Via Cell.Value property: double value = (double)row[Price].Value //2. Via IDataAccessor and IDataField: double value = (double) row.DataAccessor[Price].Value //3. Directly from the data object: double value = (double)((IList)row.DataObject)[2]; if (( double )row[ Price ].Value 30000 ) { //Filter the row return true ; } //The row is not filtered return false ; } public event EventHandler FilterUpdated; } public void FilterUsing(Grid grid) { //Initialize the grid grid.Headers.Add( new Header()); grid.Headers[ 0 ].Add( new Column( Name )); grid.Headers[ 0 ].Add( new Column( Color )); grid.Headers[ 0 ].Add( new Column( Price )); //Set filter grid.Filter = new CustomFilter(); //Populate the grid Row row1 = grid.Rows.Add( new object [] { Mercedes  Color.Black 25000 d}); Assert.IsFalse(row1.Visible); Row row2 = grid.Rows.Add( new object [] { BMW  Color.White 35000 d }); Assert.IsTrue(row2.Visible); //Set a new price for Mercedes row1[ Price ].Value = 32000 d; Assert.IsTrue(row1.Visible); } You can also get detailed explanation on Real time data filtration here

I can't see if you mean winform or wpf. Please put your post in the corresponding section.
