我试图让我的程序使用事件处理程序和tableadapters将一行添加到数据库。我可以成功添加一行到数据库，但是当我单击“btnRefresh”按钮时它不会保存。这是事件处理程序的代码。在Visual Studio中更新tableadapter数据库

Private Sub btnRefresh_Click(sender As Object, e As EventArgs) Handles btnRefresh.Click 
    Try 
     Validate() 
     CarsBindingSource.EndEdit() 
     CarsTableAdapter.Update(Me.ABVDataSet.Cars) 
     MsgBox("Refreshed Successfully") 
    Catch ex As Exception 
     MsgBox("Update failed") 
    End Try 
End Sub 

回答：

Private Sub btnRefresh_Click(sender As Object, e As EventArgs) Handles btnRefresh.Click Try Validate() CarsBindingSource.EndEdit() CarsTableAdapter.Update(ABVDataSet,"table_name") MsgBox("Refreshed Successfully") Catch ex As Exception MsgBox("Update failed") End Try End Sub
