我有一个带Datagridview的数据输入表单，我使用的是本地database.sdf文件。当我搜索某个人的特定名称时，单击“编辑”按钮将显示一个新的更新表单。数据成功传递到更新表单
要求： 要从更新表单成功更新Person的数据，数据将在Datagridview中刷新并显示当我点击Update按钮并且Update表单Closes
错误： 我首先尝试了SqlceDataAdapter ADAP.Fill（databaseDataSet，“Mainform”）; //其余的代码将显示在// // 但是当我单击“更新”按钮时，它会更新数据，但也会在DatagridView中创建整个数据的整个副本。所以我试过SqlCeDataAdapter ADAP.Update（databaseDataSet，“Mainform”）;和此代码更新数据成功并且不创建任何副本，但Datagridview不刷新，仅在我关闭并再次打开应用程序时显示数据
代码尝试： 在表格1中：
