无法设置datagridview的行可见的false [英] Unable To set row visible false of a datagridview

问题描述

我有一个 DataGridView 我在哪里设置 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;

与我的类lccls as

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

在某个事件我想使当前行不可见： p>

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

 MyGrid.Rows[5].Visible = false;

但是我无法做到这一点。相反，抛出了以下错误消息的异常：

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

与货币经理的头寸关联的行不能被作为
invisible

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？ >

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

推荐答案

搜索很多，我得到了解决方案

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