Dynamically Loading CSS Elements In Asp.net

Aug 26, 2011

I have an asp.net web app that allows users to customize some GUI aspects (such as font color, add a custom logo etc). This information is stored in the user profile database. I have a css file that populates font colors etc. The main page, loads the users profile from the database, and customizes the page accordingly.Aside from having each label with its own "font-color=", how can I display the CSS elements, based on the user profile information returned from the database?

Html - Dynamically Created Elements From Codebehind Need To Be Inserted Between Specific Elements

Sep 17, 2010

I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

Loading Array Elements Into Listbox?

Mar 7, 2009

why my code doesn't work? I want the array elements to be loaded into a listbox when the button is clicked. Is it because not all elements in my array have been filled? I've tried putting the array declaration as a global variable and as a local one (below), but the same error occurs as soon as the button is clicked - "ArgumentNullException was unhandled".

Private Sub btnLoadCustomerNames_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoadCustomerNames.Click
'String array holds maximum 100 customer names

C# - Dynamically Loading .NET Assemblies?

May 25, 2009

I am writing a program and I want the program to support plugins. I created an interface that the program must implement. I am using the following code from my main program to call the plugin:

Dim asm As Assembly = Assembly.LoadFrom(ff.FullName)
' Get the type
Dim myType As System.Type = asm.GetType(asm.GetName.Name + "." + asm.GetName.Name)
' If the type is null then we try again without the root namespace name

[code]....

I set this property from my main program and everything works. Except, after a while, m_PanelObject gets set to Nothing for some odd reason. I'm not setting it to Nothing anywhere in my program and there is no place in the plugin code that sets it to Nothing.

C# - Dynamically Loading Assemblies In .NET?

May 24, 2010

We've built a small component which takes an Id, looks up an entry in the database for an assembly/namespace/class, and dynamically loads an instance of the class that we're after. It has been working fine up until now, but when running this code in VS 2010, it's failing.

Private Function AssemblyLoaded(ByVal assemblyFile As String) As Assembly
Dim assemblies() As Assembly = AppDomain.CurrentDomain.GetAssemblies
For Each asmb As Assembly In assemblies

[Code]....

But it feels dirty. Is there a better way of checking if an assembly is already loaded, and handing that back to the caller? Are the issues above specific to .NET 4.0 or Visual Studio 2010? I haven't tried this outside the IDE as it requires fairly significant configuration.

Asp.net - Dynamically Loading User Control In MVC?

Sep 16, 2011

I have a UserControl.ascx which essentially outputs the Name and Email of the user currently logged in (stored in session variables, for the record) at the top of every page on my website. Said control is currently called by Site.Master using <%Html.RenderPartial("UserControl")%>.

It works fine when I log in for the first time and my details are displayed correctly, but when I log out and try to log in again something strange happens...

The Control itself tests the condition Session("auth"), which my controller sets to true upon authenticating a user and which it forces to false when the logout button is pressed. All session variables are cleared upon logging out.

(For the record, my user control used to check Request.IsAuthenticated rather than Session("auth") to determine the current Session State. The same issue arised.)

The problem is that when I try to log in as a different user, instead of showing the new user's information in the header, nothing appears beside Name: and Email: (see code below). I suspect this is because UserControl.ascx is not updating its state.

Ideally, I'd like a solution which would force UserControl to check Session variables every time a page is loaded. Is there a clean way to achieve this?

<%@ Control Language="VB" AutoEventWireup = "false" Inherits="System.Web.Mvc.ViewUserControl" %>
<%-- The following line works around an ASP.NET compiler warning --%>

Loading User Control Dynamically Loses Data

Apr 22, 2010

I have a created a user control. This user control I dynamically load on a page inside Telerik Panelbar control. I have done all necessary coding to save the viewstate and load this dynamically created usercontrol every time page loads.On this User control I have a asp panel. By default this panel is invisible. When user clicks a button on this user control panel is made visible. On page load of this user control I populate all the controls on this panel.Everything works fine if I dont load this use control dynamically but when I load this user control dynamically and if I make panel visible by default then only all fields on the panel are populated. But if I make by default invisible and on button click make panel visible none of the text boxes or comboboxes are populated. I populate comboboxes on page load of the userControl but inbetween postbacks all the comboboxes on the user control loose data.[code]...

Dynamically Creating Methods For Dynamically Created Buttons?

Mar 15, 2011

I have this code.

Code:
Public Class Form1
Dim NPB As Button
Dim x As Integer

[code]....

As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?

Access Objects On A Dynamically Created UserControl An A Dynamically Created Tab Page?

Dec 5, 2011

I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.

On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.

What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!
