绑定ASP.NET GridView控件到一个字符串数组 [英] Binding an ASP.NET GridView Control to a string array

问题描述

我试图绑定一个ASP.NET GridView控件控件的字符串数组，我得到了以下项目

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

一个字段或属性的名称
  '项目'没有被选定的发现
  数据源。

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

什么是正确的值，我应该为ASP的数据字段属性使用：绑定列列在我的GridView控件。下面是我的源$ C ​​$ C：

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>

code背后：

Code Behind:

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

更新

我需要有的AutoGenerateColumns 属性设置为假，因为我需要生成额外的 ASP：CommandField中列。我已经更新了我的code样本，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

一种方法是使用一个名为场传递一个类。这样，你可以给它一个名字。

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; }
}

那么你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，你可以命名你的数据字段属性。

Now you can name your DataField property

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