Good evening.

Thank you.

    I write this in the xDataGrid1_Load event:

     

     

    XamDataGrid xdg = sender as XamDataGrid;
    SummaryDefinitionCollection summaries = xdg.FieldLayouts[0].SummaryDefinitions;
    summaries.Clear();

    SummaryDefinition summary = new SummaryDefinition();
    summary.Calculator =     SummaryCalculator.Sum;
    summary.SourceFieldName =     "CassaUscita";
    summaries.Add(summary);

     

     


    the first start I get this error on line SummaryDefinitionCollection summaries = xdg.FieldLayouts[0].SummaryDefinitions; :

    Index out of range. Required non-negative value and the size of the nomire.

    if I close the contentPane where you uploaded the UserControl that contains the XDataGrid and then reopen, I receive the money without any problems.

    XDataGrid the UserControl is in a load in a contentPane.
