推荐答案

出现此错误是因为您在gridview中使用了两个数据源，即一个是linq数据源(检查设计并删除DataSourceID从gridview)和后面的代码中.

Gridview一次只能在数据源上使用.尝试删除一个.会的.

This error is coming because you have used two datasources in your gridview, i.e., one is linq data source(Check in your design and remove DataSourceID from gridview) and in code behind.

Gridview except only on datasource at a time. Try deleting one. It''ll work.

不显示?

do not show ?

protected void Button3_Click(object sender, EventArgs e)
{

    string[] cities = { "London", "Amsterdam", "San Francisco", "Las Vegas",

                    "Boston", "Raleigh", "Chicago", "Charlestown",

                    "Helsinki", "Nice", "Dublin" };


    GridView1.DataSource = from city in cities

                           where city.Length > 4

                           orderby city

                           select city.ToUpper();

    GridView1.DataBind();


}
