Dynamically create hyperlinks For English Characters from A-Z

This is how to Dynamicly build the a links of characters from A-Z , somthing like this

A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z

You may need to filter a GridView results , like displaying the list of users in which there names begins with specific character .

We can use the Repeater Control to Dynamicly generate the character links  as follows:

ASPX:

            <asp:Repeater ID="Repeater1" runat="server">
                <ItemTemplate>
                    <asp:HyperLink ID="hyp1" runat="server" NavigateUrl='<%# eval("Name","~/Target.aspx?Key={0}") %>'
 Text='<%# eval("Name") %>'></asp:HyperLink>
                </ItemTemplate>
                <SeparatorTemplate>|</SeparatorTemplate>
            </asp:Repeater>

 And the Page Code Behind:

VB:

    Private Sub BindRepeater()

        Dim dt As New Data.DataTable
        dt.Columns.Add("Name")

        Dim c As Char = "A"

        Do While Asc(c) <= Asc("Z")
            dt.Rows.Add(c.ToString())
            c = Chr(Asc(c) + 1)
        Loop Me.Repeater1.DataSource = dt
        Me.Repeater1.DataBind()
    End Sub Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        BindRepeater()
    End Sub

C#:

private void BindRepeater() 
{ 
    
    Data.DataTable dt = new Data.DataTable(); 
    dt.Columns.Add("Name"); 
    
    char c = "A"; 
    
    while (Strings.Asc(c) <= Strings.Asc("Z")) { 
        dt.Rows.Add(c.ToString()); 
        c = Strings.Chr(Strings.Asc(c) + 1); 
    } 
    
    this.Repeater1.DataSource = dt; 
    this.Repeater1.DataBind(); 
} 

protected void Page_Load(object sender, System.EventArgs e) 
{ 
    BindRepeater(); 
}
