No Postback after response.end

Posted By:      Posted Date: October 08, 2010    Points: 0   Category :SharePoint

I have build a custom action which calls the RaisePostBackEvent Event. This works fine for me. In the RaisePostBackEvent Event i made an HttpContext.Current.Response to export a file. At the end i make a HttpContext.Current.Response.End().

My Problem is, that everything seems to be fine when i click first time on my menuitem. Its executes the RaisePostBackEvent Event and i get my file for download, too.

But its not possible to click on the menuitem a second or third time. Nothing happens. The RaisePostBackEvent Event doesnt get fired. Whtas wrong here?

Here is my code:

Imports System
Imports System.Web
Imports System.Web.UI
Imports System.Web.UI.WebControls
Imports Microsoft.SharePoint
Imports Microsoft.SharePoint.Utilities
Imports Microsoft.SharePoint.WebControls
Imports System.Collections.Specialized

Namespace MyCustomActions
    Public Class MyExport
        Inherits WebControl

jQuery $(document).ready() and ASP.NET Ajax asynchronous postback

Many call it the ASP.NET jQuery postback problem, but using the technique below should make it no problem anymore. $(document).ready() isn't called after an asynchronous postback. What this means? You lose the functionality that should be executed within $(document).ready() after an UpdatePanel rendered its contents after an asynchronous postback.

jQuery live() and ASP.NET Ajax asynchronous postback

The issue is that normally $(document).ready() is called when the DOM is ready to be manipulated. But this doens't happen after an ASP.NET Ajax asynch postback occurs.

This means that the initial jQuery bindings won't be automatically available after the asynchronous postback is over. I underline "automatically" here because my last post describes more possibilities, how this issue can be worked around.

Response.BinaryWrite help needed


Hi all

Im new to .NET and stuck now, so i hope anyone can help my with my problem.

I have a MS SQL database where i have stored some documents as Binary data. I cant figure out how to retrieve them and show/download them in my browser.

I found some guides online and have try to put something together.


private void Write()
 int id = 0;
 string strID = Request.QueryString["id"];
 int.TryParse(strID, out id);

 var db = new ModelDataContext();
 var doc = db.DocumentDatas.Where(x => x.ID == id).FirstOrDefault();

 byte[] byteArray = File.ReadAllBytes(doc);


How do i fill the byteArray with the data?

Thanks in advance :)


Response.Redirect slow


I'm in the middle of migrating servers and on the new server Response.Redirect is extremely slow. It takes around 20 seconds for the browser to get the redirect. This is something that was quick on the existing server. It's an ASP.NET 2.0 application, both servers are running IIS6.

Additionally, if I "manually" do the redirect, it's fast. For example:

Existing way:


takes around 20 seconds on the new server

New way:

Response.Status = "302 Moved Temporarily";
Response.AddHeader("Location", url);

is fast on the new server.

Any ideas why Response.Redirect would be so slow on the new server?

Dynamically load user control without postback


Hi all,

I need urgent help. (c#coding)

In my base page, I have a dropdownlist control which loads different usercontrols on selectedindexchanged event.

While loading these usercontrols, my page postbacks all the page. I used updatepanel but again same problem.

Is there any way to load controls without postback? I Really need help as soon as possible.

Here is my code:

protected void Page_Init(object sender, EventArgs e)
        if (Session["control"] != null)
            string c = Session["control"].ToString();
            if (c == "1")
                iuc = (IlkogretimUC)LoadControl("~/Controls/Ilkogretim.ascx");
                dl.SelectedValue = Session["control"].ToString();
            else if (c == "2")
                luc = (LiseUC)LoadControl("~/Controls/LiseUC.ascx");
                dl.SelectedValue = Session["control"].ToString();
            else if (c == "3")
                youc = (YuksekokulUC)LoadControl("~/Controls/Yuksekokul.ascx");

no response when refreshing reportviewer


Hi guys, I've been struggling with this for some time now, but I can't figure out why it's not working. I got a gridview in which I'm selecting a specific row. This gives me a string back, which is used to load some data inside a datatable, using DAL The callback works and it's also giving the correct string to retrieve the wanted data. But when I'm trying to use this fresh data update my reportviewer (.rdlc) nothing happens. For now I'm testing the event with a simple button, but even with the button nothing happens. Does anyone know what I'm missing The DAL is working correct and I'm using .NET 3.5

<rsweb:ReportViewer ID="ReportViewer" runat="server" Font-Names="Verdana" 
                                 InteractiveDeviceInfos="(Collection)"  WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt" >
        <LocalReport ReportPath="Office\Reporting\InvoiceReport.rdlc" />                                
    protected void Button1_Click(object sender, EventArgs e)
        string strInvoiceId = "603663";

        tblInvoiceTableAdapter InvoiceAdapt = new tblInvoiceTableAdapter();
        TGU.tblInvoiceDataTable invoiceDt = InvoiceAdapt.GetIn
