Remarks
When creating custom filter values by handling the ASPxGridView.HeaderFilterFillItems event, you can use the CreateShowNonBlanksValue method to create the (Non blanks) filter item. The created item can be added to a header filter using the event argument's ASPxGridHeaderFilterEventArgs.AddValue method.
protected void ASPxGridView1_HeaderFilterFillItems(object sender, DevExpress.Web.ASPxGridViewHeaderFilterEventArgs e)
{
e.Values.Clear();
FilterValue showNonBlanksItem = e.CreateShowNonBlanksValue("Non Blank Items");
e.Values.Add(showNonBlanksItem);
}
