Solution 1

In your java script method raise a __dopostback call to a Server side method.

<script type="text/javascript">
     function YourFunction()
     {
         __doPostBack('btnTemp', '')
     }
</script>

Where btnTemp is a server side button, so write a onClick event of this button on server side, where you can do the processing and then redirect to other page.

You can have a good understanding of dopostback at DoPostBack Understanding

Solution 2

My aspx page is like:

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <script type="text/javascript">
        function CallMe() { __doPostBack('btnTemp', '') }
    </script>
</head>
<body>
    <form id="form1" runat="server">
         <asp:Button ID="btnTemp" runat="server" Text="Test" onclick="btnTemp_Click" />
         <div> <asp:Label ID="Label1" runat="server" Text="Label1"></asp:Label>
         <asp:Label ID="Label2" runat="server" Text="Label"></asp:Label></div>
    </form>
</body>

And my Server Side code is as:

protected void Page_Load(object sender, EventArgs e)
    {
        Label1.Attributes.Add("onClick", "CallMe();");
    }
protected void btnTemp_Click(object sender, EventArgs e)
    {

    }

Thats the code that I have written, I haven;t included the using statement, Page directive etc in above code.

i would like to create OnClick event for my panel. So far now the most of the google results look more or less like this: adding onclick event to aspnet label. Is there any way, to call codebehind function from javascript or panel attributes? Because I would like to Redirect user to a new page and before that save some information in ViewSTate or Sessionstate. Any suggestions?
