DataGridView过滤

发布于 2024-08-07 04:43:05 字数 382 浏览 5 评论 0原文

我正在创建一个应该能够获取任何类型列表的控件。本质上是以下代码：

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

现在我有一个文本框，我想用它来过滤网格中的数据。我认为这就像设置 bs.Filter 属性一样简单，但显然不是。 bs.SupportsFiltering 也返回 false。

这是我使用 IList 的问题吗？如果是这样，是否有另一个集合类/接口可以用来达到相同的效果？（同样，我不确定列表中对象的类型是什么。

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;    
}

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.

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.

由于不知道我要传递的类型，我导致手动过滤数据。
这是我的代码片段。效果很好。希望对于大量数据来说它不会太慢。 :: 手指交叉 ::

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;

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;
