Error with UltraGridDocumentExporter and threading

Hi,

UltraGridDocumentExporter1.Export(Me.ugvDataGrid, MyPath,
DocumentExport.GridExportFileFormat.PDF) don't work when i put this line in
a second thread .... why ?

The thread procédure:
Private Sub ThreadProcedure()
        Try
              _ugePDF.Export(_Grid, _Chemin,
DocumentExport.GridExportFileFormat.PDF)

        Finally

        End Try

    End Sub

To launch the thread:

    Public Sub Exporter()
        _ExportThread = New Thread(New ThreadStart(AddressOf
ThreadProcedure))
        _ExportThread.IsBackground = True
        _ExportThread.Start()
    End Sub

It's working with ExcelExporter ...

Perhaps that's wrong?:

Public WithEvents _ugePDF As UltraGridDocumentExporter

Public Sub New(ByVal uGrid As UltraGrid)

_ugePDF = New UltraGridDocumentExporter
_Grid = uGrid
_ugePDF.TargetPaperOrientation = Infragistics.Documents.Report.PageOrientation.Landscape
_ugePDF.TargetPaperSize = Infragistics.Documents.Report.PageSizes.Letter
_ugePDF.ImageCompressorType = ImageCompressorType.Flate
_ugePDF.AutoSize = AutoSize.None
_ugePDF.UseFileBuffer = False

End Sub

Here's the exact code that I used, which generated an outlook groupby rendered to PDF.
private void ultraButton1_Click(object sender, EventArgs e)
{

this.ultraCheckEditor1.DrawFilter = this;
Infragistics.Win.UltraWinGrid.UltraGrid grid = new Infragistics.Win.UltraWinGrid.UltraGrid();
grid.CreateControl();

grid.InitializeLayout += InitLayout;

grid.Width = 500;

grid.Height = 500;
grid.DisplayLayout.ViewStyleBand = Infragistics.Win.UltraWinGrid.ViewStyleBand.OutlookGroupBy;
grid.BindingContext = new BindingContext();
grid.DataSource = new AdventureWorksDataSetTableAdapters.vJobCandidateTableAdapter().GetData();
grid.DataBind();
Infragistics.Win.UltraWinGrid.DocumentExport.UltraGridDocumentExporter exporter = new Infragistics.Win.UltraWinGrid.DocumentExport.UltraGridDocumentExporter();exporter.Export(grid, "c:\\temp.pdf", Infragistics.Win.UltraWinGrid.DocumentExport.GridExportFileFormat.PDF);
}
protected void InitLayout(object sender, EventArgs e)
{

Infragistics.Win.UltraWinGrid.UltraGrid grid = (Infragistics.Win.UltraWinGrid.UltraGrid)sender;
grid.DisplayLayout.Bands[0].SortedColumns.Add(grid.DisplayLayout.Bands[0].Columns[0], false, true);
}

You need to specify the viewstyle for the grid to be OutlookGroupBy in order for it to perform any grouping. Try the following -

_Grid.DisplayLayout.ViewStyleBand = Infragistics.Win.UltraWinGrid.ViewStyleBand.OutlookGroupBy;

Hi!
export works fine but not the group..
what's wrong ? :
        _Grid = New UltraGrid
        _Grid.CreateControl()
        _Grid.BindingContext = New BindingContext()
        _Grid.DataSource = GridSource.DataSource
        _Grid.DataBind()

        For Each col As UltraGridColumn In GridSource.DisplayLayout.Bands(0).SortedColumns
            Dim bSort As Boolean = (col.SortIndicator = SortIndicator.Ascending)
            Dim cUltraGriCol As UltraGridColumn = _Grid.DisplayLayout.Bands(0).Columns(col.Index)
            _Grid.DisplayLayout.Bands(0).SortedColumns.Add(cUltraGriCol, bSort, True)
        Next
