DataGridView过滤 [英] DataGridView filtering

问题描述

我正在创建一个能够采取任何类型的列表的控件。基本上如下代码：

I'm creating a control that should be able to take any kind of list. Essentially the following code:

void BindData(IList list)
{
    BindingSource bs = new BindindSource();
    bs.DataSource = list;
    this.DataGridView.DataSource = bs;    
}

现在我有一个我想用来过滤我的数据的文本框格。我认为它可以像设置bs.Filter属性一样简单，但显然不是。 bs.SupportsFiltering也返回false。

Now I have a textbox that I want to use to filter the data in my grid. I figured it'd be as simple as setting the bs.Filter property but apparently not. The bs.SupportsFiltering returns false as well.

这是使用IList的问题吗？如果是这样，是否有另一个收集类/接口，我可以使用来实现相同的效果？ （再次，我不知道列表中的对象的类型是什么。

Is this an issue with me using the IList? If so, is there another collection class / interface that I can use to achieve the same effect? (Again, I'm not sure what the type is of the objects in the list.

推荐答案

不知道我的类型我通过手工过滤数据
这是我的代码片段，它的工作原理很好，希望它不会被证明是太慢的数据量较大:: ::手指交叉::

Not knowing the type I'm getting passed, I resulted in filtering the data by hand. Here's my code snippet. It works well. Hopefully it doesn't prove to be too slow with larger amounts of data. :: Fingers Crossed ::

List<object> filteredData = new List<object>();
foreach (object data in this.DataSource)
{
    foreach (var column in this.Columns)
    {
        var value = data.GetType().GetProperty(column.Field).GetValue(data,null)
                                                            .ToString();
        if (value.Contains(this.ddFind.Text))
        {
            filteredData.Add(data);
            break;
        }
    }
 }

 this.ddGrid.DataSource = filteredData;
