hi,

i have the following situation, working report with some input parameters and defined groups in report.
When i add new parameter on report, code for my groups in designer.cs file disappears. When i try access them in code they always trow null Exception.
I have some code in report  ItemDataBinding event for group manipulation.

example:

if (!string.IsNullOrWhiteSpace((string)ReportParameters["DatumOd"].Value) && !string.IsNullOrWhiteSpace((string)ReportParameters["DatumDo"].Value))
            {
                this.group2.Groupings.Clear(); 
                this.group2.Groupings.AddRange(new Telerik.Reporting.Grouping[] { new Telerik.Reporting.Grouping("=Fields.Sifra") });
                //this.group2.Sortings.AddRange(new Telerik.Reporting.Sorting[] { new Telerik.Reporting.Sorting("=", Telerik.Reporting.SortDirection.Asc) });
                this.groupFooterSection2.Visible = false;
            }
            else if (!string.IsNullOrWhiteSpace((string)ReportParameters["RazdobljeOd"].Value) && !string.IsNullOrWhiteSpace((string)ReportParameters["RazdobljeDo"].Value))
            {
                this.group2.Groupings.Clear();
                this.group2.Groupings.AddRange(new Telerik.Reporting.Grouping[] { new Telerik.Reporting.Grouping("=Fields.Razdoblje") });
                //this.group2.Sortings.AddRange(new Telerik.Reporting.Sorting[] { new Telerik.Reporting.Sorting("=", Telerik.Reporting.SortDirection.Asc) });
            }

Hi Dalibor,

I believe that if you move all of your custom code from the Designer.cs to the report constructor you will be fine. You can do the same for the code in the ItemDataBinding event, since I'm not sure an event is the correct place to do the grouping. For more information you can always read the reporting online help.
