Hi,

you can not integrate or combine two requests in single process.
my suggestion is approach jquery or asynchronous requests.to check condition on server from client using jquery thn if true in response post required data to server .to perform "then some code"

updated Answer

HTML

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title></title>
    <script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>
    <script src="Scripts/jquery-1.4.1-vsdoc.js" type="text/javascript"></script>
    <script language ="javascript" >
        function savefile() {
            $.post("default3.aspx?action=checkfile", { filename: document.getElementById("fileupload1").value }, function (data) {
                if (data == 'Yes') {
                    if (confirm("Are you Sure")) {
                      
                    }
                }
                else {

                }
            });
        }
    </script>
 


</head>
<body>
    <form id="form1" runat="server">

    <div id="maincontent"  runat="server" >
    <input type ="file" id="fileupload1" />
        <input type ="button" value ="Save File" id="btnsave" onclick ="savefile()" />
     
    </form>
</body>
</html>

And code behind file contains

C#

protected void Page_Load(object sender, EventArgs e)
{
    if (Request.QueryString["action"] != null)
    {
        if(Request.QueryString ["action"].ToString()=="checkfile")
        {
            Response.Clear();

            bool execsts = true ;
            //check wheather file is exists or not
            //if exists send response to client as Yes
            if (execsts)
            {
                //send response as Yes if it exists to confirm
                Response.Write("Yes");
            }
            else
            {
                //save file if it doesn't exists
                Response.Write("File Saved Successfully");
            }


            Response.End();
        }

    }
}

This just for bring idea only

you've to modify it for your requrement.

All the Best

Solution 6

C#

ibtnDelete.Attributes.Add("language", "javascript")
ibtnDelete.Attributes.Add("OnClick", "return confirm('Are you sure you want to delete this record?');")

This will bring up an OK/Cancel box when the button is clicked; if Cancel is then clicked the button's click event code won't run.

Hii professional

this is a java script code that may help you paste it on asp source page...

JavaScript

<script type="text/javascript">

    document.getElementById("yourButtonId").onclick = function()
 {
 var confirmation = window.confirm("Are you sure want to?"); //confirmation variable will contain true/false.

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

Happy to help...

If You want to show the alert from Page behind I mean from aspx.cs side then you can use:

protected void Button1_Click(object sender, EventArgs e)
{
ClientScript.RegisterClientScriptBlock(GetType(), "sas", "javascript:alert('success');", true);
}
