i have couple of aspx pages, both have drop down lists (DDLs) in them. A user first goes to Page1.aspx and choose a value from the DDL-1 and click on Submit button. He is then taken to the Page2.aspx which again has a DDL-2. What I want is to populate the

Web Forms :: Code Works On Aspx But Not On Ascx

Aug 21, 2010

Not sure which category to put this question in, so I will put it in here. Just to give you an idea of the layout of my solution, I have the main project, along with 2 class libraries, BLL and DAL. (Business Logic Layer and Data Access Layer) The BLL refers to the DAL and the main project refers to the BLL. I had a test website and the code worked fine, but the same code will not work on the real project. The only difference is that in the test project, the code was on an aspx code behind, whereas in the real project, it is an ascx code behind (Web User Control


The code is:


Dim connectionString As String = ConfigurationManager.ConnectionStrings("ASPNETDBConnectionString").ConnectionString

C# - ASCX And ASPX Transferring Data From One To The Other?

Mar 24, 2011

I have this page, shown below. In the ASCX file, the data is generated using a DataGrid in which a user searches for fields and it displays results based on input criteria. This is using a stored procedure and parameters to perform this search. It then returns the results, populates a datagrid, now my question is how would I go about in my ASPX page having my disk icon allow a user to download a CSV of the data that has been returned in the ASCX page. I obviously need to run a command to generate the CSV file from the database, which I have all the code for, but my question really is how do I know what the user has searched for, or what results were returned I guess best put.

C# - Validation When Converting .aspx To .ascx?

Mar 22, 2010

I'm currently converting a set of .aspx pages and the VB code behind them to .ascx and C#.

Basically the system I'm working with validates a shopping basket but with me changing the class the code inherits from I'm having issues working out what I should change it too.

I'm changing from System.Web.UI.Page to System.Web.UI.UserControl and am primarily having problems with the Validator.Add(v) element of the code below:

public override void Validate()
if (Profile.ShoppingCart == null || Profile.ShoppingCart.Items.Count == 0)
CustomValidator v = new CustomValidator();
v.ErrorMessage = "You must have at least 1 course in your basket.";
v.IsValid = false;

Caching - ASPX And ASCX Files Not Updating When Saved?

Mar 4, 2011

At some point in the last month, two web application projects that I've been working on have stopped showing updates to aspx and ascx files until IIS is restarted, or the website they belong to is reset. This seems to be very random and I can't find any reason in the web.config sections that would cause this change. What are some good places to look for a source to this issue?Current caching parts of web.config: Removing the outputCacheProfile and restarting IIS made no difference.

<add name="ClientResourceCache" location="None" enabled="true" duration="3600" varyByParam="*" varyByContentEncoding="gzip;deflate"/>

Commening out the staticConent and restarting also made no difference

<clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="1.00:00:00">
<add extension=".gif" policy="DontCache" kernelCachePolicy="CacheUntilChange" duration="0.00:01:00" location="Any" />
<add extension=".png" policy="DontCache" kernelCachePolicy="CacheUntilChange" duration="0.00:01:00" location="Any" />
<add extension=".js" policy="DontCache" kernelCachePolicy="DontCache" duration="00:01:00" location="Any" />
<add extension=".css" policy="DontCache" kernelCachePolicy="DontCache" duration="00:01:00" location="Any" />
<add extension=".jpg" policy="DontCache" kernelCachePolicy="CacheUntilChange" duration="0.00:01:00" location="Any" />
<add extension=".jpeg" policy="DontCache" kernelCachePolicy="CacheUntilChange" duration="0.00:01:00" location="Any" />

We've also tried adding .ascx and .aspx extensions with CacheUntilChange which made no difference. Other sites with these same settings aren't having the issue. Edit: Originally this state that there also was no update when the project was built, I haven't personally been able to confirm that issue but was told by another developer that was occurring.

Get Parameters Out Of An Ascx Back To Main Aspx Page?

Jun 15, 2010

I've got an aspx page that renders an ascx page with filtering capabilities. Inside the ascx page, parameters are passed as follows:

<td class="label">Plataforma</td>
<td class="field lookup"><%= Html.Lookup("s.Site", null, Url, "Sites") %></td>
<td class="label">Data</td>
<td class="field date"><%= Html.TextBox("s.Date", DateTime.Today.ToString("yyyy-MM-dd")) %></td>

I need to be able to get those parameters on the main aspx page, because they are needed for an action that is called there. How could I access these parameters?

Get A Reference To The Current Class (ascx Or Aspx) Given A Member Object?

Mar 14, 2011

Given an instance of a control SomeControl that is in a some file (could be a usercontrol/ascx, or an aspx) how can I get a reference to the class to which it belongs?

In a usercontrol, SomeControl.NamingContainer seems to be reliable.

In a page that inherits from a MasterPage, this will return a reference to the ContentPlaceHolder, not the actual class that defines the aspx. What I would want in that case is SomeControl.Page

Parent will return the parent control in the heirarchy so isn't much use.

Is there any method for getting this directly regardless of what kind of thing it is?

Make AJAX Redirects - Page_Load Methods In .aspx And In An .ascx ?

Jan 5, 2010

Ok, this is a bit different scenario. I guess I would have to think about doing it this way sort of with MVC anyway if we were actually using MVC...but we're not at the moment.So I've got and .aspx page. In that .aspx page is a user control (.ascx). And in that user control is a custom control (.cs).

The custom control has a repeater in it. So I'm showing a list of items on that .aspx through the .ascx's custom control. For each item in the repeater is a button. It's just a hyperlink, just a regular on my page When you click that button, it redirects to whatever page you're on. Since the custom control never knows what your parent .aspx page is, I'm doing a redirect to the self .aspx by doing a Response.Redirect(Request.Path). So that way it always redirects to whatever .aspx is using that user control and custom control.

So after it redirects to self, I check the querystring in the page_load of whatever .aspx is using it. If the value is true, then I handle it however the .aspx wants to. In this case when it's true, I call a method in the code behind of my .aspx that handles the action for the button. For example lets say that button was "Add to Shopping Cart", the .aspx handles that action and calls a AddToCart method in the .aspx.cs.

I'm not using an ASP.NET control for the actual hyperlink and button because I just don't need it and in my particular case I'm using a user control and a custom server control.For this instance, I had some issue where I didn't wnat to use an ASP.NET control...I forget why but the point is, no this is what it is.

So with that, I'm trying to figure out how I can apply some AJAX here call to call that method instead. I still need to somehow redirect again back to the same page like I'm doing...I'm doing the redirect in that method after all the logic at the end. I am redirecting again back to the same page, because I need my Page_Load methods in my .aspx and also in an .ascx to still fire off after that method is completed.So I am not sure where to start on this. Let me go through this once again:

Custom control has a repeater in it and in the repeater, each item has a standard HTML hyperlink (non ASP.NET control) which wraps a standard image tag (image is a button)User control contains the custom control The .aspx page contains the user control User clicks the butt on and hyperlink redirects them to the parent .aspx page that is using this custom control...so it callsResponse.Redirect(Request.Path)

In the code-behind of this .aspx, in my page_load I check a querystring flag to see if I performed that action..meaning user clicked that button. For example one of the querystring params is "AddItem" and another querystring param is "itemID". If movedItem is true, then I fire off a method called MoveItem(int itemID) Method MoveItem is called Method MoveItem redirects again back to this same .aspx using Response.Redirect(Request.Path).. this is so that the page load is hit again as well as my .ascx page load is hit. Because in both those page loads, I rebind a repeater so I can show the latest state of the lists. I call a method in my .aspx page_load which rebinds a grid and then page_load in my .ascx also calls another method which rebinds some other list

C# - Accessing Source Code Generated From ASPX/ASCX Files?

Mar 3, 2010

You've probably noticed that when you debug an error which comes from an ASPX or ASCX file (literally, not from a corresponding code-behind file), ASP.NET displays an error page showing you the source file and the line on which the error occurs. The source file being displayed is automatically generated from parsing the page/control. The question is: how can I see this source file without purposely causing an exception?

I'd love to hear that there is some programmatic way (the complexity doesn't matter) to generate source files (preferrably, .cs) from a series of ASPX/ASCX files.

Example. Consider the following ASPX page (the code-behind file may even be absent):

<%@ Page Language="C#"%>
<%@ Register Assembly="AspxGen" Namespace="AspxGen" TagPrefix="ag" %>
<head><title>Some Title</title></head>


d:DevAspxGenAspxGenDefault.aspx(9,80): error CS0103: The name 'ThereIsNoSuchProperty' does not exist in the current context

This means, theoretically I can open the .CS files passed to the compiler (namely, App_Web_sqj3krv3.0.cs and App_Web_sqj3krv3.1.cs) and see what ASP.NET has generated from my ASPX markup. Trying to rephrase the previous question: how can I obtain this file from an arbitrary ASPX file (assuming that the file is correct and hence no info will be given on where to search)?
