I have a crosstab in my report that needs dynamic columns so I am building the groups/rows/columns in the NeedDataSource method. To get me started, I set up the crosstab in the designer with 2 columns and bind it to a datatable. The Crosstab displays the data correctly. Then I reviewed the designer code, and add the groups/rows/columns exactly how it is done in the designer. Note: at this point, I am still just adding the 2 columns, so the crosstab should be exactly the same as when built in the designer. But when I bind the crosstab to the same datatable, it throws an "Index was out of range...." exception. Since the groups/rows/columns should be the same as when built in the designer, I could be missing a step prior to adding the groups/rows/columns. Currently, I am clearing all RowGroups, ColumnGroups, Body.Columns, Body.Rows, and Items from the crosstab. (then adding the rows/columns/groups) Is there anything else I need to do? Do you have any other ideas on what might cause the "Index was out of range..." exception? Here is my code:

crosstab1.RowGroups.Clear();

crosstab1.ColumnGroups.Clear();

crosstab1.Body.Columns.Clear();

crosstab1.Body.Rows.Clear();

crosstab1.Items.Clear();

crosstab1.Corner.ClearCellContent();

crosstab1.Body.Columns.Add(new TableBodyColumn(new Unit(2D, UnitType.Inch)));

crosstab1.Body.Rows.Add(new TableBodyRow(new Unit(0.26D, UnitType.Inch)));

TextBox txtBx = new TextBox() { Size = new SizeU(new Unit(2D, UnitType.Inch), new Unit(0.26D, UnitType.Inch)), Value = "=Fields.Jun2011" };

crosstab1.Items.Add(txtBx);

crosstab1.Body.SetCellContent(0, 0, txtBx);

txtBx = new TextBox() { Size = new SizeU(new Unit(2D, UnitType.Inch), new Unit(0.26D, UnitType.Inch)), Value = "=Fields.Jul2011" };

crosstab1.Items.Add(txtBx);

crosstab1.Body.SetCellContent(0, 1, txtBx);

TableGroup group1 = new TableGroup();

group1.Groupings.Add(new Telerik.Reporting.Data.Grouping("=\'ColumnGroup\'"));

txtBx = new TextBox() { Size = new SizeU(new Unit(2D, UnitType.Inch), new Unit(0.26D, UnitType.Inch)), Value = "June 2011" };

crosstab1.Items.Add(txtBx);

group1.ReportItem = txtBx;

TableGroup group2 = new TableGroup();

txtBx = new TextBox() { Size = new SizeU(new Unit(2D, UnitType.Inch), new Unit(0.26D, UnitType.Inch)), Value = "July 2011" };

crosstab1.Items.Add(txtBx);

group2.ReportItem = txtBx;

crosstab1.ColumnGroups.Add(group1);

crosstab1.ColumnGroups.Add(group2);

txtBx = new TextBox() { Size = new SizeU(new Unit(2D, UnitType.Inch), new Unit(0.26D, UnitType.Inch)), Value = "Project Name" };

crosstab1.Items.Add(txtBx);

crosstab1.Corner.SetCellContent(0, 0, txtBx);

txtBx = new TextBox() { Size = new SizeU(new Unit(2D, UnitType.Inch), new Unit(0.26D, UnitType.Inch)), Value = "Type Of Financial" };

crosstab1.Items.Add(txtBx);

crosstab1.Corner.SetCellContent(0, 1, txtBx);

TableGroup group4 = new TableGroup();

group4.Groupings.Add(new Telerik.Reporting.Data.Grouping("=Fields.TypeOfFinancial"));

txtBx = new TextBox() { Size = new SizeU(new Unit(2D, UnitType.Inch), new Unit(0.26D, UnitType.Inch)), Value = "=Fields.TypeOfFinancial" };

crosstab1.Items.Add(txtBx);

group4.ReportItem = txtBx;

group4.Sortings.Add(new Telerik.Reporting.Data.Sorting("=Fields.TypeOfFinancial", Telerik.Reporting.Data.SortDirection.Asc));

TableGroup group3 = new TableGroup();

group3.ChildGroups.Add(group4);

group3.Groupings.Add(new Telerik.Reporting.Data.Grouping("=Fields.ProjectName"));

txtBx = new TextBox() { Size = new SizeU(new Unit(2D, UnitType.Inch), new Unit(0.26D, UnitType.Inch)), Value = "=Fields.ProjectName" };

crosstab1.Items.Add(txtBx);

group3.ReportItem = txtBx;

crosstab1.RowGroups.Add(group3);

crosstab1.DataSource = ConstructDataTable();
