Dynamically Add Rows to Repeater on Button Click using C# and VB.Net in ASP.Net

Greetings again Gurus,

There are two versions of code below.

One is done in Gridview and it works great.

I am trying to use same code but this time in Repeater but it is not working.

How do I use same code in Repeater that I used in Gridview?

Thanks for your help as usual

  private void SetRowData()
    {
        int rowIndex = 0;

        if (ViewState["CurrTable"] != null)
        {
            DataTable dtCurrentTable = (DataTable)ViewState["CurrTable"];
            DataRow drCurrentRow = null;
            if (dtCurrentTable.Rows.Count > 0)
            {
                for (int i = 1; i <= dtCurrentTable.Rows.Count; i++)
                {
                    TextBox tbboatregNum = (TextBox)Gridview1.Rows[rowIndex].Cells[1].FindControl("txtboatregNum");
                    TextBox tbtaxpayerret = (TextBox)Gridview1.Rows[rowIndex].Cells[2].FindControl("txttaxpayerret");
                    TextBox tbfortaxofficeonly = (TextBox)Gridview1.Rows[rowIndex].Cells[3].FindControl("txtfortaxofficeonly");
                    drCurrentRow = dtCurrentTable.NewRow();
                    drCurrentRow["RowNumber"] = i + 1;
                    dtCurrentTable.Rows[i - 1]["boatregNum"] = tbboatregNum.Text;
