Remarks

When creating custom header filter values by handling the ASPxGridView.HeaderFilterFillItems event, you can use the CreateShowNonBlanksValue method to create the (Non blanks) filter item. Then, the created item can be added to the header filter item list using the ASPxGridHeaderFilterEventArgs.Values.Add method.

Example

using DevExpress.Web.ASPxGridView;
...
protected void ASPxGridView1_HeaderFilterFillItems(object sender, DevExpress.Web.ASPxGridViewHeaderFilterEventArgs e) {
     e.Values.Clear();
     FilterValue showAllItem = FilterValue.CreateShowAllValue("Show All");
     e.Values.Add(showAllItem);
     FilterValue showBlanksItem = FilterValue.CreateShowBlanksValue(e.Column, "Show Blanks");
     e.Values.Add(showBlanksItem);
     FilterValue showNonBlanksItem = FilterValue.CreateShowNonBlanksValue(e.Column, "Show non Blanks");
     e.Values.Add(showNonBlanksItem);
     ...
    }
