Associating a GridView with a List of Rows

Question

I have a list that I bind to a GridView, so my GridView will only have one column of these string values. I want to have the appropriate header text for this column. Please help me. See what I tried to do:

<asp:GridView ID="GridView1" runat="server" Width="95%">

<Columns>

<asp:BoundField HeaderText="My List" />

</Columns>

</asp:GridView>

And in the code behind:

List<string> myList = new List<string>();

:

:

// code to populate myList

:

:

GridView1.DataSource = myList;

GridView1.DataBind();

When I run this code, I get two columns in the GridView. The first column has heading text as “My List” and has empty rows, while the second column has heading text as “Item” and has rows with myList values. I want to have only one column in my GridView with a text heading like "My List" and rows with the values ​​of the myList object.

thank
