For example:  If you grouping using of DateTimeGroupDescription you should be able to format date as dd.MM.yyyy  instead of Apr-22

Resolution: You can use the GroupElementFormatting event to format the text in the GroupDescription elements. Please, note that the developer should add an own logic for formatting a date (for example you should take the year and month from another fields)

RadPivot prints only left columns and the columns placed on the right part of the control do not print

Drag the field contains date from field choicer control to Column data area. Then remove one of the sum field. The exception will thrown.

Workaround: Use the DLLs for NET2.0

GroupDescriptions loose the Custom Name after dragging.

Change the Decimal symbol/separator  to "," and run Excel export for the RadPivotGrid. Note that all "0,00" cells are displayed as "1" in Excel and all decimal values are displayed without decimal separator.

Another scenario is when you change the Format in the Regional settings to Russia. Then, when exporting data, the decimal separator for the GrandTotal column is not correct ".", instead of ",". However, for the data cells it is OK.

Workaround: If possible add the label filters with code
PropertyGroupDescription dateGroupDescription = new PropertyGroupDescription();
dateGroupDescription.PropertyName = "Date";

LabelGroupFilter filter = new LabelGroupFilter();
ComparisonCondition condition = new ComparisonCondition
{
    Condition = Telerik.Pivot.Core.Filtering.Comparison.IsGreaterThan,
    Than = new DateTime(2010, 6, 6)
};
filter.Condition = condition;
dateGroupDescription.GroupFilter = filter;

this.provider.RowGroupDescriptions.Add(dateGroupDescription);

Workaround: remove the localization provider before saving the layout and then add it back.

Steps to reproduce:
1. Add a RadPivotGrid to a form and populate it with data or use the one in the Demo application
2. Press Ctrl+A to select all cells
3, Press Ctrl+C to copy all cells to the clipboard

You will get an exception.

To reproduce:

Add a RadPivotGrid and a few columns, select one column and show the PrintingDialog. Select "Print Selection Only", exception will occur.

Workaround:
Use the following print style -

        }
    }
}

To reproduce:
- Open the demo application and navigate to the olap browser demo.
- Click the filter icon in the Product Line (top left corner).

To reproduce:

private void Form1_Load(object sender, EventArgs e)
{
    this.ordersTableAdapter.Fill(this.nwindDataSet.Orders);
    
    LocalDataSourceProvider dataProvider = new LocalDataSourceProvider(); 
    dataProvider.Culture = new System.Globalization.CultureInfo("ru-RU"); 
    dataProvider.ItemsSource = this.ordersBindingSource;

    dataProvider.BeginInit();
    dataProvider.RowGroupDescriptions.Add(new DateTimeGroupDescription() { PropertyName = "OrderDate", Step = DateTimeStep.Year, GroupComparer = new GroupNameComparer() });
    dataProvider.RowGroupDescriptions.Add(new DateTimeGroupDescription() { PropertyName = "OrderDate", Step = DateTimeStep.Quarter, GroupComparer = new GroupNameComparer() });
    dataProvider.RowGroupDescriptions.Add(new DateTimeGroupDescription() { PropertyName = "OrderDate", Step = DateTimeStep.Month, GroupComparer = new GroupNameComparer() });
    dataProvider.ColumnGroupDescriptions.Add(new PropertyGroupDescription() { PropertyName = "EmployeeID", GroupComparer = new GrandTotalComparer() });
    dataProvider.EndInit();

    dataProvider.BeginInit();
    dataProvider.AggregateDescriptions.Add(new PropertyAggregateDescription() { PropertyName = "Freight", AggregateFunction = AggregateFunctions.Sum });
    dataProvider.AggregateDescriptions.Add(new PropertyAggregateDescription() { PropertyName = "Freight", AggregateFunction = AggregateFunctions.Average });
    dataProvider.EndInit();

    this.radPivotGrid1.DataProvider = dataProvider;
}


Workaround:

CultureInfo russianCultureInfo = new System.Globalization.CultureInfo("ru-RU"); 
List<string> monthNames = DateTimeFormatInfo.CurrentInfo.MonthNames.ToList();

public Form1()
{
    InitializeComponent();
    this.radPivotGrid1.GroupDescriptorElementCreating += radPivotGrid1_GroupDescriptorElementCreating;
}

private void radPivotGrid1_GroupDescriptorElementCreating(object sender, GroupDescriptorElementCreatingEventArgs e)
{
    if (e.GroupDescriptorElement.Text == "Month")
    {
        e.GroupDescriptorElement.FilterPopup.PopupOpening -= FilterPopupPopupOpening;
        e.GroupDescriptorElement.FilterPopup.PopupOpening += FilterPopupPopupOpening;
    }
}

private void FilterPopupPopupOpening(object sender, CancelEventArgs args)
{
    PivotGroupFilterPopup popup = sender as PivotGroupFilterPopup;
    if (popup != null)
    {
        popup.TreeViewMenuItem.TreeElement.TreeView.NodeFormatting -= TreeView_NodeFormatting;
        popup.TreeViewMenuItem.TreeElement.TreeView.NodeFormatting += TreeView_NodeFormatting;
    }
}

private void TreeView_NodeFormatting(object sender, TreeNodeFormattingEventArgs e)
{
    DateTime date;
    int monthIndex = monthNames.IndexOf(e.Node.Text);
  
    if (monthIndex > -1)
    {
        e.Node.Text = russianCultureInfo.DateTimeFormat.MonthNames[monthIndex];
    }
}

To reproduce: 

Create a localization provider following the article - http://wwwsit.telerik.com/help/winforms/pivotgrid-localization-localization.html. When you start the app you will see that the PivotAggregateP0ofP1 is not used.

Workaround:

Use the formatting events to format the needed values - http://wwwsit.telerik.com/help/winforms/pivotgrid-formatting-appearance.html

If you have an object with string property and for all the available objects in the RadPivotgrid you have numeric values for this property with leading zero digits (e.g. "002"), it is exported in Excel as a numeric cell.

To reproduce:
- Add calculated field
- Try to set its number format, by clicking the Number Format option in the context menu in the field list (see image)

Workaround:
 Private Sub RadPivotGrid1_CellFormatting(sender As Object, e As UI.PivotCellEventArgs) Handles RadPivotGrid1.CellFormatting
        If e.CellElement.Column.Name = "Commission" Then
            e.CellElement.Text = String.Format(System.Threading.Thread.CurrentThread.CurrentUICulture, "{0:C}", e.CellElement.Value)
        End If
    End Sub

Workaround: 
PivotExportToExcelML.ExportVisualSettings = false;

To reproduce:

1. Add a RadPivotGrid and  change its theme to TelerikMetro. This theme uses Segoe UI font for its cells.
2. Export the RadPivotGrid.
3. You will notice that the font is applied to some of the cells, but for others, e.g. Grand Total the default font is set to Microsoft Sans Serif

Second scenario: use Demo application PivotGrid >> Export to Excel example. Use ControlDefault theme.
1. Ctrl + H to show the spy.  Check font for row  "Jun-1 >> Sum of Net", column "Printer stand >> 1 Free with 10".  The font is Segoe UI.
2. Run the export and check the same cell in Excel. Its font is Microsoft Sans Serif.

Workaround: use the PivotExcelCellFormatting event to specify the font.

Workaround:

    e.GroupDescriptorElement.FilterPopup.PopupOpened -= FilterPopup_PopupOpened;
