I'm wanting to insert some javascript in the body of a page using ClientScript.Register..() when a user returns to it (either by back button or on link click). When I use the back button the inline server script is never hit in debug. Any way to get the server to evaluate the code every single time the user is directed to that page.

View 3 RepliesI want to ask if I can overried a function the presents at Usercontrol that I created that Mean
I can update the function if there a need for that {Virtual,.....}
I want to override that function from the asp.net codebehind that hold that user control.
What I have is a masterpage with some tables and contentplaceholders. What I want in some pages is that a table be removed because i have 3 columns on 3 tables and i need 2 columns only(so minus one table). Now i can access the table and give it some css through code but what i give is width:0 (and visibility:hidden if ever successful). The table contains one contentplaceholder inside a <td>. I can also access the td.The problem is that the table (thus contentplaceholder) will not go away.
It remains as entity as extending the second column will just push it downside(behavior expected when the column3 with contentplaceholder is present). So is there a way to remove the table holding the contentplaceholder?Only thought is to hide it and push it right that i admit i haven't tried it yet, I suppose it would be easier to make another master page but the problem is that i want specific designs on many pages so if this does not work i would either have to make many master pages or just use simple pages.

View 8 RepliesCan someone explain to me the rules around what can and cannot be evaluated/inserted into markup using the <%# %> and <%= %> tags in asp.net?When I first discovered I could inject code-behind variables into mark-up using <%= I thought 'great'. Then I discovered that if such tags are present you can then not add to the controls collection of the page (that's a whole different question!). But <%# tags are ok.
Is there a way I can inject a code-behind variable or function evaluation into the page using <%# ?
I am trying to call a web service function within my own ASP.net (code behind) using AJAX on the page.

I want to show a loading image before the content of the whole page is loaded. How to achieve this? I'm working in ASP.NET.
View 3 RepliesI have a page which includes serveral gridviews, pulling out data from my datasources. At this stage, the parameters are set withing the page, however it will use a querystring at the end of the url. Once the page is loaded, i then have an Email function calling a HTML reader, which basically captures the content of the page and pushes to the body of the email and then emails it out.
The issue i am having is where to place this stagement. I have tried to insert the email function in the Page (load complete) event, but it still seems to send out over 20 emails, which to me, means that the page hasnt finished? loading and is constantly calling the email function.
At this stage, i need this page to load .. i cant think of any other way, i can get the data sent to an email without the interim medium; the page.
I want to add a class and initialize a JS funcion behind my nested masterpage which is being dervised from an other master page. But when I add the following code in the PageLoade event in the code behined of my derived page then it give the folowing error

In my gridview I have fields for inserting a new record in the footer.
In my objectdatasource selecting event if no records came back I bind a single mock row to force the footer to show so they can still add records. Since the row does not contain real data I hide the row.

I am creating a menu at runtime, containing this:
Code:
dividor3 = "<td onmouseover=""shomainlinks()"" style=""z-index:13001; font-weight:bold; width:10; vertical-align:center; color:rgb(180,30,40);"">ยป</td>"
The menu (there are other string components as well) is then added to a div as a literalcontrol.
Code:
<div id="mainlinks" class="tpsubmenu" runat="server" style="z-index:13000;"></div>
Everything works. But when I assign a css class to the div, the shomainlinks() function doesn't fire. Otherwise it does.
Code:
.tpsubmenu{position:absolute; display:none; width:300px; border:1px solid rgb(200,140,80); background-color:rgb(250,250,250);}
I should also tell you that I have another string, dividor4, identical but for the name of the function that does not have css styling, and that one works as it should.
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 process the data.
All I want to get done, are some update/inserts into database after the page is rendered and shown to the user. I don't want the logging to slow down the pageload for the users obviously. I want that logging or no logging makes no difference to the pageloadtime for the user at all.
I have a [WebMethod] within an aspx.cs file. It seems that whenever a second call to the method is made via AJAX before the first call is fully executed, the web method completely stops functioning until the page is reloaded.

View 2 RepliesI'm working on an ASP.net application.I had a problem with a user control I'd designed called LocationSelector. It worked great, but I couldn't use it within an ASP:UpdatePanel. I learned, by browsing SO, that I needed to put my in-line javascript in an external file and register it with ScriptManager so that there are no Response.Write calls in the Javascript.Next, I discovered that the control worked at first, but when I enclosed it within the ASP:UpdatePanel, it would stop functioning after the first AJAX postback. I read that to fix that, I needed to replace my $(document).ready call with function pageLoad() which is automatically executed with each ASP.net page load.
Several of my pages in my ASP.net application work fine (and I was really impressed with how well the framework seemed to drive the application). However, to my dismay, I discovered that my LocationSelector control no longer works at all on three of my pages. The HTML renders, but the pageLoad (which uses jQuery to bind events on control elements) does not fire.I verified this but putting alert('pageLoad'); as the first line of my pageLoad function. On the pages that work, I see the alert. On the pages that don't work, I never see the alert, even on the initial page load.What kind of problem could be causing the pageLoad function on my user control LocationSelector to execute on some pages, but not others?
