Open a Web Page according to Textbox Value

Hi,
We will learn how to Open a Web Page based on Textbox Value.
In this tutorial, we are using: Visual Studio 2010, XHTML 4.01, JavaScript, ASP.NET Ajax, C#

We put a Textbox Control in Empty Web Form. Inserted a Script Manager in Page and Used an AutocompleteExtender to Textbox. Then We wrote a method for AutoCompletion List which ,I used Static, you can change according to your need. Then created a Simple JavaScript Function and Applied to Textbox. Lets make clear through Code.

ASPX Code (XHTML):

<asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager>

<asp:TextBox ID="txtNewDate" runat="server" onblur="Redirect()"></asp:TextBox>

        <asp:AutoCompleteExtender ID="txtNewDate_AutoCompleteExtender" runat="server" DelimiterCharacters=""  Enabled="True" ServiceMethod="GetCompletionList" ServicePath="" TargetControlID="txtNewDate" UseContextKey="True" MinimumPrefixLength="1">        </asp:AutoCompleteExtender>

Now JavaScript Code which is Inserted Directly in Head Section. (JavaScript)

<script language="javascript" type="text/javascript">

        function Redirect() {

            var day = document.getElementById("<%=txtNewDate.ClientID%>").value;

            switch (day) {

                case 'hp':

                    window.location = "http://www.hp.com/";

                    break;

               case 'acer':

                    window.location = "http://www.acer.com/";

                    break;

            }

        }

    </script>

Now Code in Back End ASPX.CS (C#)

[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]

    public static string[] GetCompletionList(string prefixText, int count, string contextKey)

    {

        string[] Brands = { "hp", "acer", "dell", "lenovo" };

        return (from m in Brands where m.StartsWith(prefixText, StringComparison.CurrentCultureIgnoreCase) select m).Take(count).ToArray();  

    }

Now Try this at your Machine....
Best of Luck..
