how to dynamically add rows?

[Patrick]

I always get a nullreference exception in the report designer. I just copied the code from the InitializeComponent method and modified it to my needs.

private Table CreateTable()
       {
           Table table1 = new Table();
           table1.Name = "table1";
           //important!
           table1.RowGroups.Clear();
           table1.ColumnGroups.Clear();
           table1.Body.Columns.Clear();
           table1.Body.Rows.Clear();

           this.detail.Items.AddRange(new Telerik.Reporting.ReportItemBase[] {
           table1});
           table1.Size = new Telerik.Reporting.Drawing.SizeU(new Telerik.Reporting.Drawing.Unit(15.199901580810547D, Telerik.Reporting.Drawing.UnitType.Cm), new Telerik.Reporting.Drawing.Unit(0.99999994039535522D, Telerik.Reporting.Drawing.UnitType.Cm));
           table1.Location = new Telerik.Reporting.Drawing.PointU(new Telerik.Reporting.Drawing.Unit(0, Telerik.Reporting.Drawing.UnitType.Cm), new Telerik.Reporting.Drawing.Unit(0, Telerik.Reporting.Drawing.UnitType.Cm));

           TableGroup grpPos = new TableGroup();
           TableGroup grpCount = new TableGroup();
           TableGroup grpArtName = new TableGroup();
           TableGroup grpLaufzeit = new TableGroup();
           TableGroup grpPrice = new TableGroup();

           table1.Body.Columns.Add(new Telerik.Reporting.TableBodyColumn(Unit.Cm(1)));
           table1.Body.Columns.Add(new Telerik.Reporting.TableBodyColumn(Unit.Cm(1)));
           table1.Body.Columns.Add(new Telerik.Reporting.TableBodyColumn(Unit.Cm(1)));
           table1.Body.Columns.Add(new Telerik.Reporting.TableBodyColumn(Unit.Cm(1)));
           table1.Body.Columns.Add(new Telerik.Reporting.TableBodyColumn(Unit.Cm(1)));


           //CreateRows(table1);

           TableGroup grp = new TableGroup();
           Telerik.Reporting.TextBox txtPosValue = new Telerik.Reporting.TextBox();
           txtPosValue.Value = "=Fields.ArtikelPosition";
           txtPosValue.Name = "txtPosValue";
           txtPosValue.Size = new SizeU(Unit.Cm(1.1), Unit.Cm(0.4));

           table1.Body.Rows.Add(new Telerik.Reporting.TableBodyRow(new Telerik.Reporting.Drawing.Unit(1, Telerik.Reporting.Drawing.UnitType.Cm)));
           table1.Body.SetCellContent(0, 0, txtPosValue);


           table1.ColumnGroups.Add(grpPos);
           table1.ColumnGroups.Add(grpCount);
           table1.ColumnGroups.Add(grpArtName);
           table1.ColumnGroups.Add(grpLaufzeit);
           table1.ColumnGroups.Add(grpPrice);

           Telerik.Reporting.TextBox textboxGroupPos = new Telerik.Reporting.TextBox();
           textboxGroupPos.Value = "Pos.";
           textboxGroupPos.Size = new SizeU(Unit.Cm(1.1), Unit.Cm(0.4));
           grpPos.ReportItem = textboxGroupPos;

           Telerik.Reporting.TextBox textboxGroupCount = new Telerik.Reporting.TextBox();
           textboxGroupCount.Value = "Menge";
           textboxGroupCount.Size = new SizeU(Unit.Cm(1.5), Unit.Cm(0.4));
           grpCount.ReportItem = textboxGroupCount;

           Telerik.Reporting.TextBox textboxGroupArtName = new Telerik.Reporting.TextBox();
           textboxGroupArtName.Value = "Bezeichnung";
           textboxGroupArtName.Size = new SizeU(Unit.Cm(6.5), Unit.Cm(0.4));
           grpArtName.ReportItem = textboxGroupArtName;

           Telerik.Reporting.TextBox textboxGroupLaufzeit = new Telerik.Reporting.TextBox();
           textboxGroupLaufzeit.Value = "Laufzeit";
           textboxGroupLaufzeit.Size = new SizeU(Unit.Cm(3.5), Unit.Cm(0.4));
           grpLaufzeit.ReportItem = textboxGroupLaufzeit;

           Telerik.Reporting.TextBox textboxGroupPrice = new Telerik.Reporting.TextBox();
           textboxGroupPrice.Value = "Preis / Monat";
           textboxGroupPrice.Size = new SizeU(Unit.Cm(2.4), Unit.Cm(0.4));
           grpPrice.ReportItem = textboxGroupPrice;

           //table1.Items.AddRange(new Telerik.Reporting.ReportItemBase[] {
           //textboxGroupPos,textboxGroupCount,textboxGroupArtName,textboxGroupLaufzeit,textboxGroupPrice,txtPosValue});

           grp.Groupings.AddRange(new Telerik.Reporting.Data.Grouping[] {
           new Telerik.Reporting.Data.Grouping("")});

           grp.Name = "DetailGroup";
           table1.RowGroups.Add(grp);

           return table1;
       }

thx 4 help

The structure of the Table item is not trivial, so good understanding of the Table API is required. If you're not sure what you're doing make the changes to the table in the report designer and then use the code.

Cheers!
