How to generate alphabets A to Z in asp.net

In this article I am going to explain how to generate alphabets A to Z in asp.net

In the previous article I have explained how to change background and border ofasp.net textbox on focus using CSS, how to disable Dropdownlist some itemsbased on condition in asp.net using C#, VB.net and how to remove the selecteditem from dropdownlist in asp.net using C#, VB.net.

Implementation:

HTML Markup:

<asp:DataList ID="dtlalphabets" runat="server" RepeatDirection="Horizontal">

            <ItemTemplate>

                <asp:Label ID="lbl" runat="server" Text='<%#Eval("Value")%>' CssClass="lable" ></asp:Label>

            </ItemTemplate>

        </asp:DataList>

Generate Alphabets

Create a method to generate alphabets and show in datalist data control

C# Code:

  protected void Page_Load(object sender, EventArgs e)

    {

            GenerateAlphabetsAtoZ();

    }

    private void GenerateAlphabetsAtoZ()

    {

        try

        {

            List<ListItem> alphabets = new List<ListItem>();

            ListItem alphabet = new ListItem();

            for (int i = 65; i <= 90; i++)

            {

                alphabet = new ListItem();

                alphabet.Value = Char.ConvertFromUtf32(i);

                alphabets.Add(alphabet);

            }

            dtlalphabets.DataSource = alphabets;

            dtlalphabets.DataBind();   
}

        catch(Exception ex)

        { }

    }

VB.net Code:

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load

            GenerateAlphabetsAtoZ()

    End Sub

    Private Sub GenerateAlphabetsAtoZ()

        Try

            Dim alphabets As New List(Of ListItem)()

            Dim alphabet As New ListItem()

            For i As Integer = 65 To 90

                alphabet = New ListItem()

                alphabet.Value = [Char].ConvertFromUtf32(i)

                alphabets.Add(alphabet)

            Next

            dtlalphabets.DataSource = alphabets

            dtlalphabets.DataBind()

        Catch ex As Exception

        End Try

    End Sub
