Custom Aggregates in Q3 2009 sp2

[jimit r]

How do i add my own aggregating function in the radgridview version Q3 2009 SP2? Or rather, is there any way to obtain the aggregated value from the normal SumFunction in the footer?

I am using the same code in the sample customAggrgates
The difference is tha I populate the Gridview after the InitializeComponent but the column discount is not bringing nothing, and the agregate result is show in the top

 

 

 

public IEnumerable<ErrorRecord> SourceErrorRecords ;

 

 

 

public class ErrorRecord

 

 

 

 

 

 

{

 

 

public ErrorRecord()

 

{

 

 

// this.status = new List<string> { "valid", "invalid" };

 

 

 

 

 

 

}

 

 

public string Error_Code { get; set; }

 

 

 

public string Error_Desc { get; set; }

 

 

 

public int Rejects { get; set; }

 

 

 

public int Percentage { get; set; }

 

 

 

public double NewPercentage { get; set; }

 

 

 

public double Discount { get; set; }

 

 

 

}

 

 

public frmGroupByErrorCodeWithOutSomeCodes()

 

{

 

 

//InitializeComponent();

 

 

 

 

 

 

InitializeComponent();

 

 

Menus newMenus2 = new Menus();

 

 

 

DataTable dd = newMenus2.StoreProc("CodeReject_GetErrorCodes withoutCodes");

 

 

 

 

//LabelNumber.Content = "Records: " + dd2.Rows.Count;

 

 

 

 

 

 

 

 

 

SourceErrorRecords = GetErrorRecords(dd);

 

 

ColumnGroupDescriptor descriptor = new ColumnGroupDescriptor();

 

 

 

 

 

 

 

 

descriptor.Column = this.radGridViewError.Columns["Discount"];

 

 

 

 

 

 

 

 

descriptor.SortDirection = ListSortDirection.Ascending;

 

 

 

 

 

 

 

 

this.radGridViewError.GroupDescriptors.Add(descriptor);

 

 

 

 

 

 

 

 

 

 

 

radGridViewError.ItemsSource = SourceErrorRecords;
