Get Code - Behind File To Recognize Type Of A User Control?

Jan 18, 2011

I have a custom control in my mater page that represents a menu, let's call it CustomMenu. The control code files are located in a non special directory. I want to give each page that uses that master page the ability to access the control and, using a public property, tell the control whether or not it should render itself. I have a public property on the control to do that, and I know I can get the control by referencing Page.Master.FindControl('IdOfControlIwant');

The problem I'm having is that I can't seem to get the control Type recognized by the compiler, so when I do find the menu control, I can't actually work with it. The only way I can get the code behind to recognize the type is to register it in the ascx file, and then add at least one control to the page, which is undesirable.

Code Behind Doesn't Recognize Control ID's On HTML Page

Feb 9, 2010

I had a website with a few asp.net controls with id like:

btnSave and tbAmount

I renamed one of my controls and when I tried to use it in the code behind I get the following error.

Error 5 Name 'tbAmount' is not declared.

I was messing around trying to add new controlls rather than rename, but nothing seems to work.

And now, none of my controlls that were added to the page are recognized in the code behind. They all have the error:

Error 5 Name 'tbAmount' is not declared.

Or

Error 3 Name 'hfNoteId' is either not declared or not in the current

scope. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 33 71 NoteTender

Even my button click event handler gives me the following error:

Error 2 Handles clause requires a WithEvents variable defined in the containing type or one of its base types. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 27 91 NoteTender

I have verified that my inherits is using the correct namespace and class name.

Why Doesn't Recognize User Control

Aug 1, 2010

In my current project (ASP.Net 2.0) I have a lot of web user controls, among them "Office.ascx". Office.ascx is loaded into another controls using this line:

guide_controls_display_Office o = (guide_controls_display_Office)LoadControl("Office.ascx");

The control I am loading it into has Office.ascx registered using this line:

<%@ Register TagName="office" TagPrefix="uc" Src="Office.ascx" %>

But I get this error upon launching the web page: Unable to cast object of type 'ASP.guide_controls_display_office_ascx' to type 'guide_controls_display_Office'. Why do I get this message? I can see that the first type has "ASP." in front of it. Is that normal?

How Can I Restrict The File Type In The File Browse Menu Of An AsyncFileUpload AJAX Control Toolkit

Jul 28, 2010

I would like to restrict what they see in the file upload dialog, which is set to "All Files" by default. I understand how to validate that they only uploaded a certain file type, that is not the question here. I would just like to know how to default the file type in the file selection dialog.

Is there any way to change this to "PNG only" or "*.png"?This is using AsyncFileUpload in the ASP.NET AJAX Control Toolkit.

.net - Recognize User On Site?

Jul 23, 2010

I am looking for an implementation similar to that of what is seen on banking sites. If a user comes to the site I want them to have to pass some form of registration IE (answer a question or enter in some key). If the user closes the browser and comes back to the site again from that machine they would just be able to provide login credentails to get in.

I am not sure if this is accomplished in ASP.NET by a cookie or what type of implementation.

MVC :: Code Behind Can't Recognize Server Controls After Copied To Project From Old Webform

May 30, 2010

I migrating a large asp.net webform site to MVC. I want to mix match old asp.net web form and asp.net mvc together for sometime and gradually convert the webform model to pure mvc model.

So i copied all aspx/ascx files from the old webform site to my mvc project. Now when i compile, i get build error. Code behind files can not find any server controls inside their aspx pages.

I can solve this problem by adding a desinger.cs file for each of the aspx,ascx file but that simply is not viable for me since i am dealing with hundreds of aspx pages and user controls and i can not afford to manually add a designer file for each of them.

C# - Load User Control Given Its Type?

Mar 5, 2011

Is there a way to instantiate and use a usercontrol (.ascx) if given you have its Type (ie. typeof(MyUserControl))?With regular asp.net controls like a textbox or a dropdownlist you can just make a new instance and add it to a controls collection. This doesnt appear to work for User controls. While you can make a new instance and add it to a collection, and have all of its events fire, it will not actually render to the page. Typically you would call Page.LoadControl() with the path to the .ascxThis presents a problem if all you have is its type. How can you get the path to the .ascx to give to the LoadControl method. Ideally I would also like to not have to have a reference to the Page object

C# -pass A Generic Type With The User Control?

Aug 19, 2010

In Asp.net Web forms why must a user control be partial? I tried to remove the partial keyword and it says: Missing partial modifier on declaration of type 'test'; another partial declaration of this type exists
Where is the other declaration?I am trying to pass a generic type with the user control how can I do that? I can't unless I change the other declaration too. I couldn't find it so I removed the partial keyword.Note:
you do have 3 files if your making WebApplication but if your making website you only get 2 files?
UserControl.ascx
UserControl.ascx.cs
so in website where is the other declaration?the reason i want generic is because im making a Grid User Control so i want to pass the type the datasource is going to have.

Web Forms :: User Controls Are Null When Referenced Inside The Code Behind For The User Control?

Sep 1, 2010

I have an ASP.NET 4.0 application with some simple user controls. The user controls work fine on the design surface (VS.NET 2010), but when they're loaded during application execution, nothing shows up.

Futhermore, the various child controls of the user controls are null when referenced inside the code behind for the user control.

The code behind for the user control executes as expected, but any reference to child controls are null.

It's like ASP.NET is never parsing the ASCX to create the instances of the child controls.

File Browser Control To Replace - Input Type

Jun 17, 2010

I'm working on an ASP.NET web application for our corporate intranet users. I have a form where a user should provide a path to the file on the local network (something like "localServersomeFoldersomeFile.ext") without uploading the actual file. The issue is that users don't want to type the whole file path and want to use some kind of visual browse dialog.

The standard HTML <input type=file> element allows to browse for a file, but most of the browsers (except for IE) don't allow to access file's full path, so I think it should be done by some external component like Silverlight, Flash, Java applet etc. I tried to do it with Silverlight, but I'm getting a SecurityException when trying to access file's full path using Silverlight's OpenFileDialog class. This java applet [URL] seems to do something similar to what I'm looking for, but it's focused on uploading files - I only need to be able to get file's full path and pass it to the server as a string.
