Footer aggregate missing in a virtualized grid with allowsorting=true

In a virtualized grid (EnableVirtualization="false" Height="400" AllowGrouping="true") the footer only shows if I set an initial group of columns before data loading and it doesn't update if I delete the group and select new data.

If the grid is not virtualized, the footer shows and actualizes without problem.

Hi Daniel, 

Greetings from Syncfusion. 

Query: Footer aggregate missing in a virtualized grid with allowsorting=true 

Based on your details, we suspect that you are facing issues with showing footer aggregate value with sorting property. We have checked your reported problem with the provided details and we could not able to reproduce the reported problem. The footer aggregate information is shown properly in virtualization enabled grid with AllowSorting property. Find the below sample for your reference. 


Also, we need some details regarding your reported problem. Could you please share the below details which will be helpful to validate and provide a better solution. 

  • Full Grid code snippets.
  • Reproduce the reported problem in the provided sample and revert back to us / share a simple reproduceable sample if possible.
  • Video demonstration the problem.
  • Whether did you facing issues with virtualization and displaying footer information? Since you have shared code as EnableVirtualization as false.
  • More details about your requirement.

Regards, 
Rahul

Hi  Rahul,

Could you check your project sample loading data after a button click instead of using OnInitialized? The aggregates are not shown.


SfGrid<Order> grid;

public List<Order> GridData { get; set; }
protected override void OnInitialized()
{
}
private async Task LoadData()
{
     List<Order> Order = new List<Order>();
     int Code = 10000;
     for (int i = 1; i < 10000; i++)
     {
          Order.Add(new Order(Code + 1, "ALFKI", i + 0, 2.3 * i, false, new DateTime(1991, 05, 15), "Berlin", "Denmark", new DateTime(1996, 7, 16), "Kirchgasse 6"));
          Order.Add(new Order(Code + 2, "ANATR", i + 2, 3.3 * i, true, new DateTime(1990, 04, 04), "Madrid", "Brazil", new DateTime(1996, 9, 11), "Avda. Azteca 123"));
          Order.Add(new Order(Code + 3, "ANTON", i + 1, 4.3 * i, true, new DateTime(1957, 11, 30), "Cholchester", "Germany", new DateTime(1996, 10, 7), "Carrera 52 con Ave. Bolívar #65-98 Llano Largo"));
          Order.Add(new Order(Code + 4, "BLONP", i + 3, 5.3 * i, false, new DateTime(1930, 10, 22), "Marseille", "Austria", new DateTime(1996, 12, 30), "Magazinweg 7"));
          Order.Add(new Order(Code + 5, "BOLID", i + 4, 6.3 * i, true, new DateTime(1953, 02, 18), "Tsawassen", "Switzerland", new DateTime(1997, 12, 3), "1029 - 12th Ave. S."));
          Code += 5;
      }
      GridData = Order;
}
