    i have a solution for you, may be it help you, for using that same message box or conformation dialog of c# in Asp.Net, first you should add namespace,

    Using System.Windows.Forms;

    then, where you want to call a message box or conformation dialog, you can just call it as simple as in c#, like:

    DialogResult dialogResult = MessageBox.Show("Are you shure?", "Some Title", MessageBoxButtons.YesNo);

        if (dialogResult == DialogResult.Yes)
    {
        Response.Redirect("Page.aspx");
    }
    else if (dialogResult == DialogResult.No)
    {
        MessageBox.Show("You Select Nothing to do... :(");
  }

    I think, I explained properly, sorry for any mistake....

    You can do this using JavaScript. Include this snippet in your code -

    <script type='text/javascript'>
    document.getElementById("someButtonId").onclick = function() {
        var confirmation = window.confirm("Are you sure?"); //confirmation variable will contain true/false.

        if(confirmation) { /* Write code for Yes */ }
        else { /* Write code for No */ }
    }
</script>

    .aspx markup

    <head runat="server">
    <title>Sample Page</title>
    <script type="text/javascript">
      function doSubmit(){
            var confirmation = window.confirm("Are you sure?");
            document.getElementById("HiddenField1")["value"]=confirmation;
            return true;
        }
    </script>
</head>
<body>
    <form id="form1" runat="server" onsubmit="return doSubmit()" >
    <div>
        <asp:HiddenField ID="HiddenField1" runat="server" />
        <asp:Button ID="Button1" runat="server" Text="Button" />
    </div>
    </form>
</body>

    Code-behind

    protected void Page_Load(object sender, EventArgs e)
{
    if (HiddenField1.Value == "true")
    {

    }
    else
    {

    }
}

    You can use

    window.confirm

    for this.

    It displays a modal dialog with a message and two buttons, OK and Cancel.

    window.confirm

    Eg:

    if (window.confirm("Want to see my mood ring?")) 
{ 
    // wants to continue
}
else
{
   // cancel the action
}

    Edit:

    You can also develop custom message boxes using jQuery. Here is a nice one

    jQuery Impromptu

    window.alert(); window.confirm(); and window.prompt(); This is I guess what you are looking for.

    You can use the confirm JavaScript function, but that will be limited to OK/Cancel as options. If this is not what you want, you can lean on the VBScript MsgBox client-side function. Bear in mind that doing so will only work with Internet Explorer.

    function PerformDelete(id)
{
  if(confirm("I am about to delete this record.  Is this ok?"))
  {
    //your code here
  }
}
