Hi everyone..

 I want to know how can I use confirm message "Yes - No"  for example "when I want to delete" by using Alert

cause with MsgBox it needs to install framework in client ...

thank you

use OnClientClick="return fnConfirm()" in button.

write a function name:

and write this:

<script language="javascript" type="text/javascript">
        function fnConfirm()
        {
            return confirm("Are you sure?");           
        }
        
    
    </script>

please mark as answer if this helps u

there are multiple ways to do it, also depends on where and which control will fire it...take a look here for your options: http://forums.asp.net/p/1433767/3223533.aspx#3223533

basically, the javascript "return confirm('Are you sure you want to delete?')" will do it ...you can use it inline or do a .Attributes.Add in the codebehind

<asp:Button runat="server" ID="DeleteButton" CommandName="Delete" Text="Delete" OnClientClick="return confirm('Are you sure you want to delete this record?');" />

<asp:Button ID="btnDelete" runat="server" Text="Delete" OnClientClick="javascript:return confirmation();" />

To display normal alert pop up in the code behind:

ClientScript.RegisterStartupScript(Page.GetType(), "Alert", "alert('Done perfectly.');", true);

To call a java script function in the code behind:

ClientScript.RegisterStartupScript(Page.GetType(), "confirmation", "javascript:return confirmation();", true);

(Ths is to call the confirmation java script function I wrote in my previous post.)

Thank you it works good
