使用对象列表填充 UserControl Gridview [英] Populate a UserControl Gridview with a List of Objects

问题描述

我有一个名为原因"的对象列表，其中包含两个属性代码"和文本".我想用它来填充 Gridview 的 UserControl.但是，我不明白如何将 gridview 链接到原因列表并实际设置要使用的对象数据.

I have a List of an object called "Reasons" that contains two properties "Code" & "Text". I want to use this to fill a UserControl of a Gridview. However, I don't understand how to link the gridview to the List of Reasons and actually set which data to use from the object.

我认为该方法是将数据源设置为列表，但是，这不起作用，因为它似乎用任何行填充了 gridview.有没有更好的方法来解决这个问题?

I would assume the approach would be to set the datasource to the List, however, that is not working as it does seem populate the gridview with any rows. Is there a better approach to this problem?

推荐答案

我假设您在 winform C# 中执行此操作.它在 asp.net 的 C# 代码隐藏中应该非常相似.下面是一些示例代码，您可以轻松地根据您的 obj 类型进行自定义:

I am assuming you're doing this in winform C#. It should be fairly similar in C# codebehind for asp.net. Here's some sample code you can easily customize to your obj type:

/// <summary>
/// The test class for our example.
/// </summary>
class TestObject
{
    public string Code { get; set; }
    public string Text { get; set; }
}

void PopulateGrid()
{
    TestObject test1 = new TestObject()
    {
        Code = "code 1",
        Text = "text 1"
    };
    TestObject test2 = new TestObject()
    {
        Code = "code 2",
        Text = "text 2"
    };

    List<TestObject> list = new List<TestObject>();
    list.Add(test1);
    list.Add(test2);

    dataGridView1.DataSource = list;
    dataGridView1.DataBind();
}
