implement javascript message in Code behind C#

Question

I need a code segment to call a javascript function recordInserted() which shows up an alert, from my following code behind method,

protected void add_Click(object sender, EventArgs e)
    {
        String gradename = txt_gradename.Text;
        int allocatedclasses = Int32.Parse(txt_allocatedclasses.Text);
        String headid = txt_head_id.Text;
        int numberofstudents = Int32.Parse(txt_numberofstudents.Text);

        db = new DBConnection();
        db.getConnection();
        db.executeUpdateQuery("INSERT INTO Grade (GradeName,AllocatedClasses,GradeHeadID,NumberOfStudents) VALUES ('"+gradename+"','"+allocatedclasses+"','"+headid+"','"+numberofstudents+"')");

//I Need to call it from here before redirecting
        Response.Redirect("AdminReferenceGradeAdd.aspx");
    }

Please helpp me with this.

I have tried the following but never worked,

Page.ClientScript.RegisterStartupScript(this.GetType(),"Call my function","recordInserted()",true);

This will never work .. beacuse you are saying to redirect.
when you say Response.Redirect every thing which you have prepared to send is not sent,instead response is redirect to a new page.So your client script never reaches to browser. you can use it like this :-

Page.ClientScript.RegisterStartupScript(this.GetType(),"Call my function","recordInserted();window.location.href='wwW.google.com'",true);

use window.location.href to redirect to your page("yourpage.aspx').

Try this:

ClientScript.RegisterClientScriptBlock(typeof(Page), "Call your function", "recordInserted()", true);

Or try calling Javascript function after a second:

ClientScript.RegisterClientScriptBlock(typeof(Page), "Call your function", "setTimeout('recordInserted()', 1000)", true);

It didn't work, simply redirected to the aspx page without showing up the alert! :(
