my javascript follow:

<script type="text/javascript"> $('#clicktoadd').click(function () {     var newrow = "<tr><td> @wg1.gethtml(htmlattributes: new { id = "tablegrid" },columns: wg1.columns(wg1.column("condition", format: @item => html.dropdownlist("condition", (ienumerable<selectlistitem>)model.sourcetablemodel[0].condition, "select condition", new { style = "width:100px", @class = "condition" })), wg1.column("sourcetable1", format: @item => html.dropdownlist("sourcetable1", (ienumerable<selectlistitem>)model.sourcetablemodel[0].sourcetablename, "select source 1", new { style = "width:100px", @class = "sourcetablea" })), wg1.column("columnnames", format: @item => html.dropdownlist("columnnames", new selectlist(string.empty, "value", "text"), "select column", new { id = string.empty, style = "width:100px", @class = "field1" })), wg1.column("operator", format: @item => html.dropdownlist("operator", (ienumerable<selectlistitem>)model.sourcetablemodel[0].operator, "select operator", new { style = "width:100px", @class = "operator" })), wg1.column("sourcetable1", format: @item => html.dropdownlist("sourcetable1", (ienumerable<selectlistitem>)model.sourcetablemodel[0].sourcetablename, "select source 2", new { style = "width:100px", @class = "sourcetablea" })), wg1.column("columnnames", format: @item => html.dropdownlist("columnname", new selectlist(string.empty, "value", "text"), "select column", new { id = string.empty, style = "width:100px", @class = "field1" })),wg1.column("condition", format: @item => html.dropdownlist("condition", (ienumerable<selectlistitem>)model.sourcetablemodel[0].condition, "select condition", new { style = "width:100px", @class = "condition" }))))</div></td></tr>";     $("#webgrid tbody: last").append(newrow); }) </script>

my edited webgrid follow:

@{ webgrid wg1 = new webgrid(model.sourcetablemodel);  }  <table> <tr>     <td>         <div id="grid1">             @wg1.gethtml(     tablestyle: "gridtable",     headerstyle: "gridhead",             rowstyle: "gridrow",     footerstyle: "gridfooter",             alternatingrowstyle: "gridaltrow",             htmlattributes: new { id = "tablegrid" },     columns: wg1.columns(     wg1.column("condition", format: @item => html.dropdownlist("condition", (ienumerable<selectlistitem>)model.sourcetablemodel[0].condition, "select condition", new { style = "width:100px", @class = "condition" })),     wg1.column("sourcetable1", format: @item => html.dropdownlist("sourcetable1", (ienumerable<selectlistitem>)model.sourcetablemodel[0].sourcetablename, "select source 1", new { style = "width:100px", @class = "sourcetablea" })),     wg1.column("columnnames", format: @item => html.dropdownlist("columnnames", new selectlist(string.empty, "value", "text"), "select column", new { id = string.empty, style = "width:100px", @class = "field1" })),     wg1.column("operator", format: @item => html.dropdownlist("operator", (ienumerable<selectlistitem>)model.sourcetablemodel[0].operator, "select operator", new { style = "width:100px", @class = "operator" })),     wg1.column("sourcetable1", format: @item => html.dropdownlist("sourcetable1", (ienumerable<selectlistitem>)model.sourcetablemodel[0].sourcetablename, "select source 2", new { style = "width:100px", @class = "sourcetablea" })),     wg1.column("columnnames", format: @item => html.dropdownlist("columnname", new selectlist(string.empty, "value", "text"), "select column", new { id = string.empty, style = "width:100px", @class = "field1" })),     wg1.column("condition", format: @item => html.dropdownlist("condition", (ienumerable<selectlistitem>)model.sourcetablemodel[0].condition, "select condition", new { style = "width:100px", @class = "condition" }))     )     )         </div>     </td> </tr>  <tr>       </tr>  <tr>     <td>         <input type="submit" value="add contact" id="clicktoadd" />         <input type="submit" id="submitbutton1" value="save" />        @using (html.beginform("whereview", "home", formmethod.post))        {         <input type="submit" id="nextbutton" value="next" />        }     </td> </tr> </table>

respective javascript dynamically adding new row :

<script type="text/javascript"> $('#clicktoadd').click(function () {     var newrow = $("#webgrid tbody tr:last").clone();     $("#webgrid tbody").append(newrow); }) </script>

it didnt work expected
