DevExpress.Web.ASPxGridViewHeaderFilterEventArgs e)
{
if (e.Column.FieldName != "FieldName") return;

// Example 1: Equals to 50
FilterValue filterItem1 = new FilterValue();
filterItem1.DisplayText = "Filter Value1";
filterItem1.Value = "50";
e.Values.Add(filterItem1);
// Example 2: Equals to 100
FilterValue filterItem2 = new FilterValue("Filter Value2", "100");
e.Values.Add(filterItem2);
// Example 3: Greater than 50
FilterValue filterItem3 =
new FilterValue("> 50", null, string.Format("[FieldName] > {0}", 50));
e.Values.Add(filterItem3);
// Example 4: Clear Filtering
FilterValue showAllItem = FilterValue.CreateShowAllValue("Show All");
