记录更改时触发的WinForms事件 [英] WinForms events that fire when the record changes

问题描述

我正在将MS Access程序转换为C＃Windows窗体。表单包含一个Datagridview，应限制为1到4个条目。在MS Access版本中，我使用"on current";在记录更改和加载表单时触发。它会在
中禁用子项中的addrow 函数。什么会等于记录指针更改时触发的事件。我需要在用户向datagridview添加行后以及记录更改时进行检查。  

 int MaxRows = 4; 
 if（shiftPrintersDataGridView.Rows.Count< = MaxRows）
 {
 shiftPrintersDataGridView.AllowUserToAddRows = true; 
} 
其他
 {
 shiftPrintersDataGridView.AllowUserToAddRows = false; 
}

I am converting a MS Access program to C# Windows form. The form contains a Datagridview that should be limited to 1 to 4 entries. In the MS Access version I use "on current" that fires when the record changes and when the form is loaded. It will disable\enable the addrow function in the subform. What would the equal to a event that fires when the record pointer changes. I need to check after a user adds a row to the datagridview and when the record changes.  

            int MaxRows = 4;
            if (shiftPrintersDataGridView.Rows.Count <= MaxRows)
            {
                shiftPrintersDataGridView.AllowUserToAddRows = true;
            }
            else
            {
                shiftPrintersDataGridView.AllowUserToAddRows = false;
            }
