将 ASP.NET GridView 控件绑定到字符串数组 [英] Binding an ASP.NET GridView Control to a string array

问题描述

我正在尝试将一个 ASP.NET GridView 控件绑定到一个 string 数组，我得到以下项目:

I am trying to bind an ASP.NET GridView control to an string array and I get the following item:

具有名称的字段或属性在所选项目上找不到项目"数据来源.

A field or property with the name 'Item' was not found on the selected data source.

我应该为 GridView 控件中 asp:BoundField 列的 DataField 属性使用什么正确值.这是我的源代码:

What is correct value I should use for DataField property of the asp:BoundField column in my GridView control. Here is my source code:

ASPX 页面

<asp:GridView ID="MyGridView" runat="server" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField DataField="Item" />
        <asp:CommandField ButtonType="Link" ShowSelectButton="true" SelectText="Click Me!" />
    </Columns>
</asp:GridView>

背后的代码:

string[] MyArray = new string[1];
MyArray[0] = "My Value";
MyGridView.DataSource = MyArray;
MyGridView.DataBind();

更新

我需要将 AutoGenerateColumns 属性设置为 false，因为我需要生成额外的 asp:CommandField 列.我已经更新了我的代码示例以反映这种情况

I need to have the AutoGenerateColumns attribute set to false because I need to generate additional asp:CommandField columns. I have updated my code sample to reflect this scenario

推荐答案

一种方法是将一个具有单个命名字段的类传递给它.这样，您就可以为其命名.

One method is to pass it a class with a single, named field. That way, you can give it a name.

public class GridRecord
{
    public string MyValue { get; set; }
}

然后将您的字符串数组转换为类的列表

Then convert your string array to a list of the class

string[] MyArray = new string[1];
MyArray[0] = "My Value";
List<GridRecord> MyList = (
    from ar in myArray
    select new GridRecord
    {
        MyValue = ar
    }).ToList();
MyGridView.DataSource = MyList;
MyGridView.DataBind();

现在您可以命名您的 DataField 属性

Now you can name your DataField property

<asp:GridView ID="MyGridView" runat="server" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField DataField="MyValue" />
    </Columns>
</asp:GridView>
