    Remove window.location.href = window.location; from the alert function, and rely on reloading the data on postback.

    I am using this below code but i dont why its never working, 


     System.Text.StringBuilder sb = new System.Text.StringBuilder();
      sb.Append("<script language='javascript'>function ChangeColor() {");
      sb.Append("window.location.href = window.location; ");
     //Render the function definition. 
     if (!ClientScript.IsClientScriptBlockRegistered("JSScriptBlock"))
       ClientScript.RegisterClientScriptBlock(this.GetType(), "JSScriptBlock", sb.ToString());
    //Render the function invocation. 
    string funcCall = "<script language='javascript'>ChangeColor();</script>";
      if (!ClientScript.IsStartupScriptRegistered("JSScript"))
            ClientScript.RegisterStartupScript(this.GetType(), "JSScript", funcCall);

    A javascript window.location.href = windows.location does not go to the server and fetch new data.  It loads the page from the browser's cache.  Since you want to reload the page from the server, why use that?  The save button does a post back.  Use "IsPostBack" in the code behind page to reload the data, if it needs special handling and won't fetch new data on each load.
