ASPxGridView - How to return the number of visible data rows excluding group rows

To change the number of visible data rows excluding group rows, do the following:

- Define the TotalSummary item:

[ASPx]
<TotalSummary><dx:ASPxSummaryItemFieldName="City"SummaryType="Count"ShowInColumn="City"DisplayFormat="{0} Item(s)"/></TotalSummary>

- Handle the grid's BeforeGetCallbackResult, PreRender, and DataBound events;

- Call the ASPxGridView.GetTotalSummaryValue to obtain the number of rows;

- Set this value as SettingsPager.Summary.Text.

I have written this as an extension method.
It expects that a KeyFieldName is set if it should work...

public static void FixGridItemCount(this ASPxGridView grid)
       {
           if (string.IsNullOrWhiteSpace(grid.KeyFieldName))
           {
               return;
           }
           grid.DataBound += FixGridItemCountEventHandler;
           grid.PreRender += FixGridItemCountEventHandler;
           grid.BeforeGetCallbackResult += FixGridItemCountEventHandler;
           var firstKeyFieldName = grid.KeyFieldName.Split(';').FirstOrDefault();
           if(firstKeyFieldName != null)
           {
               grid.TotalSummary.Add(new ASPxSummaryItem
                                     {
                                         FieldName = grid.KeyFieldName,
                                         SummaryType = SummaryItemType.Count,
                                     });
           }
       }   
                                                
       private static void FixGridItemCountEventHandler(object sender, EventArgs e)
       {
           var grid = sender as ASPxGridView;
           if(grid != null)
           {
               if (string.IsNullOrWhiteSpace(grid.KeyFieldName))
               {
                   return;
               }
               var firstKeyFieldName = grid.KeyFieldName.Split(';').FirstOrDefault();
               if (firstKeyFieldName != null)
               {
                   var asPxSummaryItem = grid.TotalSummary[firstKeyFieldName];
                   if (asPxSummaryItem != null)
                   {
                       var itemCount = (int) grid.GetTotalSummaryValue(asPxSummaryItem);
                       grid.SettingsPager.Summary.Text = MembercareGlobal.GridViewPagerSummaryText.Replace("[itemCount]", itemCount.ToString());
                   }
               }
           }
       }
