How do you databind a DataSet to an Excel Worksheet from a VSTO Plugin?

Posted on 2008-09-30

I am pretty sure that the key is a listObject but I cannot figure out how to create one in code.

Here is my Setup:
Visual Studios 2008
Visual Studio Template: Excel 2007 Addin
Code Executed from a UserControl.

So far I have the code calling a webservice and returning a DataSet. I have the populated dataset but cannot get the data from that dataset into the active worksheet.

I have seen a few examples of how to do this but all of them seem to be from a different project type (Excel 2007 workbook from what I can tell) and the same commands do not seem to be available.

If someone could show me some sample code of a Dataset being bound in someway to an excel worksheet it would be greatly appreciated.

Got It, finally after a full day researching just this one item:

Attached is the slightly modified version for those having a simular issue:
/// <summary>
        /// Submits Report and populates Excel with the results.
        /// All parameters should have been validated prior to calling this method.
        /// </summary>
        private void SubmitReport()
                ReportService.ASGReportsServiceClient sc = new ExcelReportPlugin.ReportService.ASGReportsServiceClient();
                ReportService.ReturnCode oReturn = new ExcelReportPlugin.ReportService.ReturnCode();
                DataSet ds = sc.ExecuteReport(ut, SelReport, ref oReturn);
                if (oReturn.Result == ExcelReportPlugin.ReportService.Code.cSuccess)
                    //Bind Dataset to the Active Excel Sheet.
                    Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)Globals.ThisAddIn.Application.ActiveSheet;
                    Microsoft.Office.Interop.Excel.Range rng = AddData(ds.Tables[0], worksheet);
                    Addtable(rng, "ThisIsMyTable");                    
                    throw new Exception(oReturn.Description, oReturn.Exception);
            catch (Exception e) { ExceptionHandler(e); }
        /// <summary>
        /// Add data to the sheets, with the columns names at the top 
        /// </summary>
        /// <param name="dataTable">The data to be added to the sheet</param>
        /// <param name="sheetToAddTo">The worksheet to add the data to</param>

        private Microsoft.Office.Interop.Excel.Range AddData(System.Data.DataTable dataTable, Microsoft.Office.Interop.Excel.Worksheet sheetToAddTo)
            //create the object to store the column names
            object[,] columnNames;
            columnNames = new object[1, dataTable.Columns.Count];
            //add the columns names from the datatable
            for (int i = 0; i < dataTable.Columns.Count; i++)
                columnNames[0, i] = dataTable.Columns[i].ColumnName;
            //get a range object that the columns will be added to
            Microsoft.Office.Interop.Excel.Range columnsNamesRange = (Microsoft.Office.Interop.Excel.Range)sheetToAddTo.get_Range(sheetToAddTo.Cells[1, 1]
           , sheetToAddTo.Cells[1, dataTable.Columns.Count]);
            //a simple assignement allows the data to be transferred quickly
            columnsNamesRange.Value2 = columnNames;
            //release the columsn range object now it is finished with
            columnsNamesRange = null;
            //create the object to store the dataTable data
            object[,] rowData;
            rowData = new object[dataTable.Rows.Count, dataTable.Columns.Count];
            //insert the data into the object[,]
            for (int iRow = 0; iRow < dataTable.Rows.Count; iRow++)
                for (int iCol = 0; iCol < dataTable.Columns.Count; iCol++)
                    rowData[iRow, iCol] = dataTable.Rows[iRow][iCol];
            //get a range to add the table data into 
            //it is one row down to avoid the previously added columns
            Microsoft.Office.Interop.Excel.Range dataCells = (Microsoft.Office.Interop.Excel.Range)sheetToAddTo.get_Range(sheetToAddTo.Cells[2, 1],
            sheetToAddTo.Cells[dataTable.Rows.Count + 1, dataTable.Columns.Count]);
            //assign data to worksheet
            dataCells.Value2 = rowData;
            //release range
            dataCells = null;
            //return the range to the new data
            return sheetToAddTo.get_Range(sheetToAddTo.Cells[1, 1],
           sheetToAddTo.Cells[dataTable.Rows.Count + 1, dataTable.Columns.Count]);
        /// <summary>
