Word Interop C#: Insert new page using existing page
<p>I have a word template file which contains a table and it has 11 rows and 3 columns. So there are 33 cells in table on first page. I fill these cell with some data, however if number of records are greater than 33 say 66, I am creating two files, each containing 33 records. I want to create single file which will contain all 66 records and there should be two pages in one file instead of two separate files. How should I do it?</p>

<p>Following is the code I am using to create one doc file.</p>

<pre><code>private static string FillTemplate(List&lt;ClientListItem&gt; clients, string fileName)
    {
        //Filled document file name
        var savedFileName = string.Empty;
        //Search template file in current directory
        var templateFilePath = System.AppDomain.CurrentDomain.BaseDirectory + "templateFile.doc";

        #region Generate file for labels

        object missing = System.Type.Missing;
        // Create Word application
        WORD._Application app = new WORD.Application();

        try
        {
            Print("Creating label document.");
            // Create new file
            WORD._Document doc = app.Documents.Open(templateFilePath);

            //Print("Creating app selection object");
            WORD.Selection selection = app.Selection;

            //If the template file contains tables
            if (selection.Tables.Count &gt; 0)
            {
                //Use first table
                //Table's are accessed with starting index as 1 not 0
                var tableToUse = selection.Tables[1];

                //Counter for number of parent caregivers inserted
                var counter = 0;
                //Number of parent caregivers
                var numberOfParentCaregivers = clients.Count;
                //Loop on each row
                //Rows are accessed with starting index as 1 not 0
                for (int rowIndex = 1; rowIndex &lt;= tableToUse.Rows.Count; rowIndex++)
                {
                    //Loop on each column
                    //Columns are accessed with starting index as 1 not 0
                    for (int columnIndex = 1; columnIndex &lt;= tableToUse.Columns.Count; columnIndex++)
                    {
                        //If counter has reached to its limit
                        if (counter + 1 &gt; numberOfParentCaregivers)
                        {
                            //Stop
                            break;
                        }

                        //If current column index is even
                        if (columnIndex % 2 == 0)

<p>Please suggest changes so that I can create any number of pages based on number of records to add in template file.</p>

<p>Thanks,
