Accessing Controls In An Aspx Page?
Jun 28, 2010
We have some code which is designed to build up a key/value pair of controls on a ASP.NET webforms page and their values. We use the "Controls" collection and recursion to build up this key/value pair.
The only issue is that ascx controls don't appear to come back in the "Controls" collection. Instead we get the controls on the ascx.
Something similar to the following code:
[Code]....
The subCtl is never a ascx control. Is there a way to get a list of the ascx controls on page or better still a different collection that contains both types?

I am working on a page called Edit.aspx and on that page is a User Control.
Note: I need to access the User Control from a button that is on the Edit Page. Once I get a handle of the User Control then I need to access a DataList on that user control and finally I need to get the ID of a dropDownList
on the User Control
This is all the code I have,Goal: From the Edit page I want to drill backwards to the UserControl/DataList/DropDownList
'Geting the user control
Dim ctrl2 As UC_SiteTemplate2 = CType(Page.LoadControl("~/UC/SiteTemplate2.ascx"), UC_SiteTemplate2)
'accessing drop down list from user control
Dim xListNumber1 As DropDownList = New DropDownList()
xListNumber1 = ctrl2.FindControl("DDLOrderList1")

I have an aspx page and I want to access an application on the client after seeking user permission. Both the windows application and the website are to be made in VB.NET.
EDIT: Here is the problem. From my .aspx webpage in vb.net, a visitor clicks on a link on my site, and if my winform is not already loaded on their desktop, it is then loaded with the users permission. This application should auto-load on the user's site at boot up time and always be in the background running. Make it an extremely thin client, taking the least cpu and bandwidth from the user, and running as a silent background process until needed.
Whenever the user visits one of my many websites, IN ANY BROWSER, somehow - the app running in the background communicates with the .aspx on one of my sites, and exchanges a silent username password identifying client winform app to the online .aspx app on my website.
Then the .aspx on my site PASSES a url such as "www.somewebsite.com" to the app running in the background, the background app then does a http request from the client's computer, not from my .aspx server, so the client's cookies and ip are visible to "www.somewebsite.com" server. The client collects the html for that page, stores it as a string, and also saves the ascii of that webpage as another string.
Both strings then are PASSED BACK to my .aspx website that the client is visiting, and the .aspx app then stores these results in a database.

I am new to silverlight and I am wondering if it is possible to access silverlight object data from the aspx page that host it. Or have silverlight write to a hidden field on the page on client side.
What I am trying to do is to use silverlight to upload file via WCF (client to WCF Service directly instead of posting data back to the web server then forwarded to WCF service). When uploading a large file, user can still do some data entry etc. And once the upload is done have it write some data return by the WCF service to the aspx's hidden field and postback to the server on submit.

There is one user control say uControl.ascx. This has a public property Message. There are 2 aspx pages Default.aspx and Home.aspx which has the user control uControl.ascx. When a sumit button from Default.aspx is clicked some action takes place and the value for Message is set and then execution is redirected to Home.aspx. In Home.aspx the value for Message is lost.
Is there anyways that the value of Message is retained for both the aspx pages?

I have a control in a 'window control library' which handles - 'drag and drop' files from computer to a listbox control, I then reference this .dll in .aspx (See code below). Now, when i try to access this through webserver for drag
and drop files i get following errror - The type of the first permission that failed was : System.Security.Permission.FileIOPermission.
How do I handle this, so that drag and drop of files can happen over the webpage residing at webserver.

I have a master page with a textbox that I want to use for a search, and display the results on the content page.
I've dragged in the datasource to the content page, and configured the formview to use that datasource... almost.
The issue I'm having is that on the last step of the configure datasource wizard where you select the parameters, I want to select the master page textbox control for the search parameter... but of course it's not available in the list. The list only allows me to choose controls from the content page.
How do I set this master page search box as the parameter for my datasource?

I have a problem i am trying to work out the best method with my limited skills. Im using vb.net(VS 2010) I am using a dll for an IFrame , which is call from code behind. On my site I havea masterpage which has two gridviews. ( GrdViewWebBureau is the one i am using for this query) GrdViewWebBureau is contained within an update panel and updated on a timer control trigger. GrdViewWebBureau updates the page with file counts and status from our clients. I can click on any one of the cells and the code behind is fired. What I am trying to do is put an IFrame on the master page and every time a user clicks on the grid, the Iframe is fired up.
I have tested the iframe and vb code behind from a dummy page and it works, however when the Iframe is on the master page it doeant work. What I am tryingh to achieve is that no matter what page a user is on the site, they will be able to click on the GrdViewWebBureau and the iframe will fire with the correct childpage. Each webPage may also have an Iframe as well, so i dont know if it is possible to make the IFrame global and just call that control ?? I have no idea if 1 this is possible with the code i have and 2, if i have the brains to understand the who what why and when.

This is my html:
Code:
<!-- ADD PRINTER -->
<asp:Panel ID="AddPanel" runat="server" Visible="false" CssClass="aspPanel">
<h1>Add Printer</h1>
<p><asp:Label ID="lblPrinterEmailAddress" OnLoad="ProcesstextValues" runat="server" Text="Common/Label/EmailAddr" CssClass="aspLabel" />
[Code]......
When the user hits the Save button, AddSaveChanges_Click() is called. In that procedure, I want to make sure the user has entered a valid email in txbPrinterEmailAddress. The problem is when I reference RegExEmailValidator in my code behind, I get object reference not set to an instance. This is my code when I detect the invalid email
Code:
Else
Logwriter.LoggerWrite(String.Format("Page is NOT valid and {0} is an invalid email id", txbPrinterEmailAddress.Text), "MyLog")
'EditPanel.Visible = True
'ShowListPanel.Visible = False
'AddPanel.Visible = False
RegExEmailValidator.Enabled = True
RegExEmailValidator.Validate()
End If
And my log entries are:
11/22/2011 1:40:37 PM Page is NOT valid and xxxxxx is an invalid email id
11/22/2011 1:40:37 PM EXCEPTION in AddSaveChanges_Click() - Object reference not set to an instance of an object.Why is RegExEmailValidator not an instantiated object?

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" %>
<html>
<head><title>Some Title</title></head>
<body>
[Code]....
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)?

I need to be able to access simple page controls like a textbox from my page class. So if I have a simple aspx page with a textbox on it, I'm trying to do something like this. i'm not using codebehind btw:
[Code]....
I thought maybe I could pass a reference to the page into the class, something like:

But that's not working either. How can I access page controls from my class?

I'm wondering how I can go about accessing page controls from a separate class I've made. I've tried a few things I found using google, but no luck :(
What I'm trying to do is keep a function that is used often, in a global class.
The function then accesses a page literal and calls ScriptManager.RegisterStartupScript. I was hoping this is possible, so then this function wouldn't have to be copied to all of the pages.
