无法设置数据网格视图的行可见假 [英] Unable To set row visible false of a datagridview

问题描述

我有一个 DataGridView，我在其中设置了 DataSource:

I have a DataGridView where I set DataSource:

taskerEntities te = new taskerEntities();
var OMsMasterDescriptiveIndicators = te.MyTable.Select(x => new lccls {Id = x.Id, name = x.name }).ToList();
MyGrid.DataSource = OMsMasterDescriptiveIndicators;

使用我的 class lccls 作为

public class lccls
    {
        public string Id { get; set; }
        public Nullable<decimal> name { get; set; }
    }

在某个事件中，我想让当前行不可见:

At a certain event I want to make the current row invisible:

 MyGrid.Rows[5].Visible = false;

但我无法做到这一点.而是抛出异常并显示以下错误消息:

But I am unable to do this. Instead an exception is thrown with the following error message:

不能制作与货币经理职位相关的行隐形

Row associated with the currency manager's position cannot be made invisible

我怀疑原因与设置DataSource有关，但为什么呢?

I suspect the reason is related to setting DataSource, but why?

推荐答案

搜索了很多，我得到了 解决方案

After searching a lot, I got the solution

CurrencyManager currencyManager1 = (CurrencyManager)BindingContext[MyGrid.DataSource];  
currencyManager1.SuspendBinding();
MyGrid.Rows[5].Visible = false;
currencyManager1.ResumeBinding();
