How to hard-code a GridView in my .aspx file? - asp.net

Question

I want to have a GridView with static data in it, not linked to any database or data source, and I would like to hard-code it directly in my aspx file.
I'm brand new to ASP.NET and have no idea what I'm doing, and for whatever reason I can't find anything online about how to do this.
I'm trying to create a one-column table with a heading of "Hello World" and two data items, "Hello" and World". Here is what I'm trying, but nothing is showing up on the page when I run it:
<asp:GridView ID="GridView" runat="server">
<Columns>
<asp:TemplateField HeaderText ="Hello World">
<ItemTemplate>
<asp:Label ID="lblHello" runat ="server" Text ="Hello"/>
</ItemTemplate>
<ItemTemplate>
<asp:Label ID="lblWorld" runat ="server" Text ="World"/>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

You want to assign either IEnumerable, DataSet or DataTable to display data in GridView.
<asp:GridView ID="GridView" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField HeaderText="Hello World">
<ItemTemplate>
<asp:Label ID="lblHello" runat="server"
Text='<%# Eval("Text1") %>' />
<asp:Label ID="lblWorld" runat="server"
Text='<%# Eval("Text2") %>' />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
public class Item
{
public string Text1 { get; set; }
public string Text2 { get; set; }
}
protected void Page_Load(object sender, EventArgs e)
{
GridView.DataSource = new List<Item>
{
new Item {Text1 = "Hello", Text2 = "World"}
};
GridView.DataBind();
}
Updated:
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
GridView.DataSource =
new Dictionary<string, string> { { "Hello", "World" } };
GridView.DataBind();
}
</script>
<asp:GridView ID="GridView" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField HeaderText="Hello World">
<ItemTemplate>
<asp:Label ID="lblHello" runat="server"
Text='<%# Eval("Key") %>' />
<asp:Label ID="lblWorld" runat="server"
Text='<%# Eval("Value") %>' />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
