Hi,

I have managed to successfully create Pivot Grids from code behind, the definition of the pivot grid, rows, columns and aggregates and filters are stored in SQL Server, I am able to easily create the grid at run time and display it. The sorting, column filters, row filters all work well. However the PivotGridReportFilterField defined when clicked fail with 

 

[NullReferenceException: Object reference not set to an instance of an object.] Telerik.Web.UI.PivotGridFilterWindow.InitializeControls() +904 Telerik.Web.UI.PivotGridFilteringManager.CreateFilterWindow() +90 Telerik.Web.UI.PivotGridFilteringManager.SetUpFilterWindowControls() +14 Telerik.Web.UI.RadPivotGrid.CreateChildControls(IEnumerable dataSource, Boolean dataBinding) +723

 

In the code behind, I construct the grid as follows:

foreach (var def in defList)
                {
                    if (def.ReportFieldType == (int) ReportFieldType.RowFieldForTable)
                    {
                        // Define Rows                         var rowField = new PivotGridRowField();
                        PivotGrid.Fields.Add(rowField);
                        rowField.DataField = def.Fieldname;
                        rowField.UniqueName = def.Fieldname.Replace(" "string.Empty);
                    }
                    else if (def.ReportFieldType == (int) ReportFieldType.ColumnFieldForTable)
                    {
                        // Define Columns                         var colField = new PivotGridColumnField();
                        PivotGrid.Fields.Add(colField);
                        colField.DataField = def.Fieldname;
                        colField.UniqueName = def.Fieldname.Replace(" "string.Empty);
                    }
                    else if ((def.ReportFieldType == (int) ReportFieldType.CountFieldForTable) ||                             (def.ReportFieldType == (int) ReportFieldType.AverageFieldForTable) ||                             (def.ReportFieldType == (int) ReportFieldType.SumFieldForTable))
                    {
                        //Define Aggregrates                         var aggregateField = new PivotGridAggregateField();
                        PivotGrid.Fields.Add(aggregateField);
                        aggregateField.DataField = def.Fieldname;
                        aggregateField.UniqueName = def.Fieldname.Replace(" "string.Empty);
  
                        if (def.ReportFieldType == (int) ReportFieldType.CountFieldForTable) aggregateField.Aggregate = PivotGridAggregate.Count;
                        if (def.ReportFieldType == (int) ReportFieldType.AverageFieldForTable) aggregateField.Aggregate = PivotGridAggregate.Average;
                        if (def.ReportFieldType == (int) ReportFieldType.SumFieldForTable) aggregateField.Aggregate = PivotGridAggregate.Sum;
                    }
                    else if (def.ReportFieldType == (int) ReportFieldType.FilterFields)
                    {
                        var filterField = new PivotGridReportFilterField();
                        PivotGrid.Fields.Add(filterField);
                        filterField.DataField = def.Fieldname;
                        filterField.UniqueName = def.Fieldname.Replace(" "string.Empty);
                        //filterField.FilterType = PivotGridReportFilterActionType.Includes;                     }
                }

 

Any help in resolving this issue would be much appreciated.

Thanks

Hi,

If it helps,What I have noticed is that if I use List<object> as a data source for the Pivot Grid, the Pivot Filter works as expected. However in the Need Datasource  event if I use a dynamic SQL and populate the pivot grid and then click on the filter that is when the filter fails to load, that is the filter window does not load.

Thanks
