Re-direct the user on the page first load

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :ASP.Net

Hi all,

Hope I can get a quick bit of help on the best way to proceed with a security related question.

When my main page loads I would like it to complete a check against a database to make sure it's 'recognised'. The check would involve passing a parameter from the Web.Config file to a MSSQL database. If the database comes back with a positive result (via a stored proc), the application should continue to run. If it does not come back with the OK, it should alert the user, possibly with a redirect.

I have the DB setup and the stored proc running well. I can call the proc and compare it to the web.config value. I set up the code to compare the values inside session_start of Global.asax, redirecting via response.redirect("errorPage.aspx") if it didn't.

First time around it worked great. I gave the web.config file a fake value and the page re-directed me as required. The only problem being I could change the address bar URL to another page name and it loaded correctly. I guess it saw the session as started and didnt run the check.

I finally tried putting in a session.abandon() before the redirect, the the pages just loop forever until I broke the debugger.

What's the best way to do this check, against any page request in the solution?

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");

Knowing the event occured in user control in current page




      My web application has user control which uses third party controls called Devexpress controls. The user control is a menu  and is part of the Master page. It is placed there because this needs to be available in all the pages. My user controls raises a even on item clicked. Now, My question is that Is there any way to know that the event has occurred in page_load of the current page in which I am in?

How to process data AFTER page is completely loaded for the user?


I have some logging that has to be done, which are some database update or inserts.

However this logging is of no importance to the user, so I only want to process the data/logs after the page is completed for the user.
As of now, if I process the data while the page is loading, I go from 1.4 to 2.0 speed (server side time processing of code), which is quite a bit comparing it is of no use to the user.

So I want this code only executed after that the page is complete.

I've been checking out Ajax, async pages etc, but the problem is it still gets executed before the page is rendered to the client, which means the client will have to wait longer then it is not being processed.

I've been checking out Threadpool.queueBackgroundWorker, however if I get it correct, this will still be executed before the page is shown to the user, as it has to complete before the prerender.

Then I thought about creating a new thread, and do the processing there, which would not have my page waiting to complete the data/logging.
However when I have 100 or 200 users loading pages at the same time, then that would mean I would be creating 200 threads on those loads, which I doubt will be good for performance. So if I want to solve this, I would have to create my own threadpool and only assign for example a max of 40 threads to it which can pr

Slow page load during a list query one time during the day


We have a monitoring tool set to check to see if the home pages for our 3 web apps load in under 60 seconds every 10 minutes.  All 3 web apps load in under 3 seconds on every 10 minute check except for one exception.  One check every day one of the web app's home page takes longer than 60 seconds to load.  This happens at 11:45PM when there is very little user usage on the environment.  The characteristics of this page are as follows: The only thing on the page is a list view web part which was added by the browser.  The page has not been customized with SPD or code at all.  The list that it pulls is a simple links list that has 281 items on it.  The view pulls all 281 items and displays them in sets of 100.  I cannot find any associated event in the server events and/or SharePoint ULS logs nor are there any daily sharepoint timer jobs running at that time.  Our full index happens at midnight with incremental happening hourly.  Our enviroment is 2 WFEs, 1 App/indexer and we have a separate SQL cluster backend.  

Could someone lead me possibly in the direction I should take next in my troubleshooting?

User Control not accessing the value of the properties send to it from the aspx page.


I have a dynamic accordion on a page. Set its datasource to an object of paged data source.The user control is in the accordions content template. When i was writing code the properties were showing but after giving the values of databases as


<uc:UserControl1  runat="server" Property1='<%#DataBinder.Eval(Container.DataItem,"columname1")%>' Property2='<%#DataBinder.Eval(Container.DataItem,"columname2")%>'  ></uc:UserControl1>


but the values shows null, these properties are shown as textboxes text property by user control.

MoreOver when I checked the values of database Items.So i made a textbox instead of usercontrol here as

<asp:TextBox ID="txtTest" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"Columname1")%>'></asp:TextBox>

It is showing the correct value. And if i pass the value directly it is also showing correctly like

<uc:UserControl1  runat="server" Property1="XYZ")%>' Property2="ABC")%>'  ></uc:UserControl1>

. where I am wrong

the problem is eval is not passing the value to usercont

page load timeouts and http 500 on MOSS2007


Hi All

I'm hoping someone can point me in the right direction re troubleshooting. We have a MOSS server farm - 3 WFE 1 APP 1 SQL cluster. All Server 2008 sp1 x64. We see occasional http timeouts (HttpException (0x80004005): Request timed out) with associated http 500 error. I have enabled failed request tracing and can see the following:

SiteId 754431215
AppPoolId SharePoint - intranet.*********.com80
ConnId 1610966466
RawConnId 0
RequestURL http://intranet.*********.com:80/Pages/default.aspx
RequestVerb GET

and then later in the trace:

ModuleName IsapiModule
Notification 128
HttpStatus 500
HttpReason Internal Server Error
HttpSubStatus 0
ErrorCode 0
ErrorCode The operation completed successfully. (0x0)

The problem happens on other pages too but the rest of the time the page is returned in less than 5 seconds. The server app logs and sharepoint ULS logs do not give any more detailed info. What I want to know is what other troubleshooting step can I take for http500 errors.

Long execution times for Search pages even after 4th or 5th user has accessed the same page.

Hi Guys We have a Sharepoint 2010 farm with two NLB web fronts ends, a Index server and a two box SQL cluster. The same problem also occurs on a dev box which has Sharepoint 2010 and SQl server running on the same single box. When a user access the search or advanced search page we get long execution times of between 15 and 30 seconds.  The strange thing is that the user will have a slow response the first time, then they are fine for a period of an hour or two and then they hit the slow response again.  Below i have copied info from the developer dashboard.  Does anyone have a suggestion of where to start tackiling this issue.
