如何获得html.Append的输入值

Question

如何获取在VB.NET中用html.Append()进行的输入的值？

我有此代码，并且效果很好@

        Dim dt As DataTable = Me.GetData()

        Dim html As New StringBuilder()

        html.Append("<thead>")
        html.Append("<tr>")
        For Each column As DataColumn In dt.Columns
            html.Append("<th>")
            html.Append(column.ColumnName)
            html.Append("</th>")
        Next
        html.Append("</tr>")
        html.Append("</thead>")

        html.Append("<tbody>")
        For Each row As DataRow In dt.Rows

            html.Append("<tr>")
            For Each column As DataColumn In dt.Columns

                If (column.ColumnName = "False") Then
                     ''' i want get value of this input '''
                    html.Append("<td><input type='checkbox'  ID='checkall' value='false' ></td>")
                Else
                    html.Append("<td>")
                    html.Append(row(column.ColumnName))
                    html.Append("</td>")
                End If
            Next
            html.Append("</tr>")
        Next
        html.Append("</tbody>")


        tableProcessNotAttibuted.Controls.Add(New Literal() With {
           .Text = html.ToString()
         })
