推荐答案

具有EmptyDataText的DataGridView组件属性-Windows窗体应用程序 [^ ]

尝试执行以下操作.基本上，dataset.fill返回查询返回的行数

Try following.Basically dataset.fill returns number of rows returned by your query

int rows = DatasetName.fill(dataadapter,"tablename");
if(rows <= 0)
{
  //Add a row to data grid and display your msg
}
else
{
  //do what needs to be done
}

<EmptyDataTemplate>
                                                <table width="100%">
                                                    <tr>
                                                        <td class="ob_gNRM" style="height: 40px; text-align: center">
                                                            There are no records available.
                                                        </td>
                                                    </tr>
                                                </table>
                                            </EmptyDataTemplate>
