</table>
</div>

<!-- Form content goes here -->
<button type="submit" id="b2" class="btn btn-primary">Export</button>
</form>

    Hello,

    I have been looking into your question and what I understand is that you want to export to excel only the selected rows from your igGrid.

    What I can suggest as an approach is to use ig.GridExcelExporter. You will handle the rowExporting event of the GridExcelExporter, which is fired for each exported row from the grid to Excel.

    $.ig.GridExcelExporter.exportGrid($("#grid"),{
       fileName: "igGrid",
},
{
   rowExporting: function (sender, args) {
   }
});

    First you will get the id of each exported row from the grid.

    var id = args.rowId;

    Then you will get all the selected rows with igGridSelection and the selectedRows method.

    var selectedRows = $("#grid").igGridSelection("selectedRows");

    You will go through the selected rows and check if the taken id of the exported row currently matches the id of the selected rows and if so then the row is selected then you will export this row and if it does not match the id then this row is not selected, and you will not export it.

    for (var i = 0; i < selectedRows.length; i++) {
      if (selectedRows[i].id === id) {
            return true;
       }
}
return false;

    This will happen when the export button is pressed.

    $("#export").igButton( {
                labelText: $("#saveChanges").val(),
                click: function(e)
                {
                     $.ig.GridExcelExporter.exportGrid($("#grid"),{
                            fileName: "igGrid",
                      },
                      {
                            rowExporting: function (sender, args) {
                             var id = args.rowId;
                             var selectedRows = $("#grid").igGridSelection("selectedRows");
                             for (var i = 0; i < selectedRows.length; i++) {
                                 if (selectedRows[i].id === id) {
                                    return true;
                                  }
                              }
                              return false;
                            }
                      }
                      );
               }
          });

    The described scenario could be observed here:

     

    In addition, I have prepared small sample illustrating this behavior which could be found here. Please test it on your side and let me know how it behaves.

    If you require any further assistance on the matter, please let me know.
