This is similar to my last post but with a different purpose.I have built a custom control, but when I set the properties for it... ALL instances of that control on my page grab the exact same property. I need to be able to set the property to "abc" for one instance of the control on my page, and then set the exact same proprty to "xyz" for a different instance of the control on the same page.

I have built a Custom Control Class that makes it much easier to build a side bar element in my html.
The problem I am running into is that when I set the "Text" property, the last time I set it gets used for every instance of the control on my page. This is my first time doing this, so I'm assuming I'm missing something basic.

What I've done is create a User Control Library (Project) and I've added a single User Control to that project. The control contains a single FlowLayoutPanel, and I created a Property on the control itself to pass the FlowDirection from the Control to its FlowLayoutPanel child.
Build, reference, component appears in the Toolbox and everything works fine, but the property on the control does not appear in the Properties window when I go to edit it at design time.
In our IDE, for example, Visual Studio, if we display the properties of a System.Windows.Forms.Button control, we see some properties that expose anoter set of properties. For example: FlatAppearance, Font, Location, Margin, etcetera.I would like to do something similar in a custom control.I know the code behind is wrong, but here is an example of what I´m trying to do:
Public Class StateOfMyCustomControl
Public Enum EnumVisibility
Visible
[code]....
In my IDE, in the properties window of my custom control, I would like to see my property State, with the possibility of display it to set the properties Visibility and EventManagement.
I want to do a class that have properties like font, which will have other properties, such as name, size, unit,bold.
<TypeConverter(GetType(ExpandableObjectConverter))> _
Class TestingClass
'Some property here
End Class
Is it possible to make a form that can set the properties on a custom control in the designer? What I mean is I want to know if it is possible to show a dialog that allows you to set the settings for a certain property like if you were adding items to a listbox.

View 2 RepliesIs there a way to not put the project name in the Inherits attribute?
I am working with vb and I have multiple projects, that have multiple web pages. In each of these projects I create controls that are reused in the web pages.
Each control I have is declared like this:
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="MenuBarControl.ascx.vb" Inherits="**projectName**.MenuBarControl" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
When I want to copy the control into another project I have to change the **projectName**. Having to change the project name for each project makes the code not reusable. Changes made to specific projects each time is not reusable.
I want to be able to omit the project name in the Inherits attribute. When I do that now I get an error

I've created a user control with a simple text box and a corresponding label and added a few custom control properties. When added to a form, I'm trying to loop through all control of this type and evaluate the custom property. In the below, the cntl.MyCustomProperty is not recognized. I can evaluate the property when I check each user control on the form by name, but not by using the loop below. I would much rather use the loop as it is much cleaner.
For Each cntl As Control In Me.Controls
If (TypeOf cntl Is MyUserControl) And cntl.MyCustomProperty = "ABC" Then
''Do some stuff

I've created a Custom Control, and I will be placing a large number of instances of that Custom Control on my xaml page. In working with that Custom Control in the VB Code Behind, how do I do the following?
How do I reference the name of the Custom Control (in my VB code) which was clicked with the MouseLeftButtonDown event? For example, if I have 10 instances of my Custom Control in xaml, each with a different x:name (say 1-10), when a particular instance is clicked, how can I see which one was clicked? I've tried a number of things including e.OriginalSource.Name (which returns the component within the control which was clicked and not the name of the instance of the control). My Custom Control consists of numerous parts and pieces (Rectangles, Lines, Text, etc). Each of these items is a part of my layer. In VB code, once I can reference a particular Control, how can I hide or change certain parts of that control (such as hiding a Line, and changing the text). Also, I need to modify more than just the control which was clicked, so I need to be able to access properties of all of the controls, not just what was clicked. For example, if I click Control instance Test1, I also need to modify Test2, Test3, and Test5 in some way.
Here is some test code I through together as part of a Silverlight project using MS Blend 2. My control is much larger, and I need 200 - 250 instances/copies of that custom control, so I really need to know which control instance/copy was clicked.

How to expose Events
I have previously used the arguments of a contentsResized event on a Winforms richtextbox to get the new size of my RTB. I am now developing a WinForms app with a custom WPF RichTextBox. My whole reason for doing this is to use the out-of-the-box spellchecker. I need my RichTextBox to expand and collapse vertically as the text is changed. The elementhost will also have to resize to allow the whole RTB to display on-screen.
