VS 2010 : Custom Control DLL Reference Greyed Out In Toolbox?
Apr 10, 2012
I'm trying to add a custom panel to my toolbox using a dll file, but when I add it as a reference it only appears as greyed out - and this is only after I click "Show All" in the toolbox.Everything builds fine in the Class Library project I used to create the custom control. Here is the simple
Imports System.Windows.Forms
Public Class pnDoubleBuffered
Inherits Windows.Forms.Panel
Public Sub New()
[code]....
I build the project, open my main project where I want to use the control. Then I click "Choose All" from the toolbox and add the reference using ".NET Frameworks Components". I find my dll file and click OK. Then nothing is added to the toolbox. I manage to see the control greyed out when I click the "Show All" option.

I have been trying to add an SQLDataAdapter control onto a webform in Visual Basic 2008 professional and Express editions. This control and others remain greyed out even when selected; they can only be seen when 'Show All' is selected in the toolbox. Is it that these controls are not available in the type of form?
I've checked various forums but have not seen a clear answer. I've tried some of the solutions proposed but none has worked. I've also reinstalled the application; then uninstalled, rebooted, reinstalled, but to no avail.

I made a custom control that is a 15x15 grid designed to show a tiled map. Inside I have a class that inherits from pictureBox. The problem comes when I try to place my DLL inside the toolbox. When I click "browse" and select my DLL to import it simply import my class inheriting pictureBox instead of the whole package.
Here is a picture of my files. Grid.vb is the control, clsTile is the pictureBox class and the other one is irrelevant. [URL]

I made a customized TextBox that I'd like to permanently add to the toolbox. But when I close the project that I created it in, my new control also disappears and I have to copy/paste or import the class-code every time I want to use it. Is there a way to get the control in the toolbox "forever"?I tried to enclose the class in a "Namespace CustomClasses" statement and changed the root namespace in the project properties to "CustomClasses", but nothing of what I tried is permanent. I prefer to store my classes in a "real" root namespace, in the same root as the microsoft and system namespaces.

I have a solution with about 5 projects, the main (startup) project is a windows forms project while the others are control libraries that contain some custom controls. The main winforms project however also contains some custom controls.
Recently, the controls in the main winforms project have stopped appearing in my toolbox. The controls from the other control library projects appear just fine, but none of the controls in my main project will show...
Some of the projects are VB, some are C#.
I have tried everything I know to fix it:Delete bin/debug folders and restart
Build, build, build, build, and build Target the same .NET Framework version and CPU platform in all projects Build again Nothing works...
All projects target .NET Framework 4.0 and compile for the x86 platform (since I am using Access db). All projects build successfully, no errors. I can run the solution just fine. I can even declare and add the controls in code and they work just fine. They just don't show up in the toolbox so I can't drag them to my form and I have to dig into the designer code everytime, which is really annoying!

In THIS Thread:NickThissen Said:Quote:It will appear in the toolbox even if you put it in the current project, instead of a control library project.No, it does not have to be in a control library, nor does it have to be a UserControl, to appear in the Toolbox. Any class inheriting (either directly or indirectly) from Control or Component will appear in the Toolbox. Since RadioButton inherits from Control, and your control inherits from RadioButton, your control inherits from Control too, so it will appear in the Toolbox. I have successfully created a pretty cool custom control. I Built the project and have added the a reference to the .dll form a new Windows forms project. It works great, as long as I do something like THIS:
Dim ThisControl As New MyCustomControl
ThisControl.Top = 40
ThisCOntrol.Left = 40
[code]....

I got a third party control from a website after googling.Inorder to use that control, I simply right-clicked the Toolbox and selected "Choose Item". Then Browse to that dll file location and selected that file.Now it is added to the toolbox. But do I have to register the dll now ? Or, will it work when I distribute my app ?

I have created a custom user control (JCUserControl), and I am using it in the Main Window. And my Main Window has no codebehind. I have this in the JCUserControl codebehind:
Private Sub ImmediateRadioButton_Checked(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles ImmediateRadioButton.Checked
SomeTextBox.IsEnabled = False
End Sub
When I run it, it fails with the NullReferenceException. If I comment out the SomeTextBox.IsEnabled = false, it runs without any problems.
Edit: Found out that I could just check if the radio buttons are loaded before doing whatever I want to do.
Private Sub ImmediateRadioButton_Checked(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles ImmediateRadioButton.Checked
If ImmediateRadioButton.IsLoaded Then
SomeTextBox.IsEnabled = False
End If
End Sub

I created some custom controls which I use quite often and I thought if I add them once to my ToolBox they just will be there next time I start up VS2008; however, that does not seem to be the case! Each time I start VS2008 I have to re-add that controls (which is quite annoying!). Is there a trick / way of having them there permanently?

The code below loads 4 Tab Pages at runtime to a TabControl. If I have UserControls in my toolbox, I can't just drag and drop the user control onto these TabPages because they don't exist yet! How do I accomplish this dynamic loading of UserControls onto the Tab Pages as they are created?
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;

How do I inherit an existing control (user control) and add it to the ToolBox?

I was asked to create an application that has a custom control that acts as a button. I managed to do almost all the requirements except the one for the KeyPress event. The customer wants to click the "Alt + C (for example)" to trigger the button click event in this case for a Cancel button. I did the code and it works fine ONLY when that custom control has the focus on it. But when it loses it, it doesn't. I don't know how to make the form accepts that KeyPress and sends to the custom control. I tried to set the form's KeyPreview property of the form to Ture but it didn't work too.
By the way, I know that it would work by writing the code in the KeyPress of the form but that's not the requirement because the user control will be used as a standalone component for many projects.

I'm developing custom .net themes, and this relies on GDI+ -- I've been able to do this mainly with a ThemeBase released on another website. Now, however, whilst inheriting another control, I am Unable to inherit the ThemeBase which means I have to design the control a little differently -- which relies on me being able to manipulate the 'OnPaint' event of the control's design.The control's 'OnPaint' event is never fired, and I don't know why. Here's the entire textbox code.[code]

Does VS 2008 have a control availible like the toolbox control from within the studio? I've looked through the list in the toolbox for choose items and am not finding it, but since I don't know what it would be called I might be over looking it.

I figured it out. Check out the finished control [URL]..I'm trying to make myself a simple 'star rating' control.
It would have the properties:
StarCount (number of stars)
StarValue (number of stars highlighted)
I want to draw the stars using GDI+, have them highlight on mouse over, and change the StarValue when clicked.I have an idea on how to do this from experience with working with forms, but I'm having some difficulties with the Control development part. I couldn't find any tutorials which didn't inherit a control (such as a checkbox or button), and I have no idea how to make my control editable in the designer.
I think what I need to do is create StarCount as a property like this:
[Code]...
I also want to execute my drawing code at design time, so I can see the stars while laying out a form. as a side note to that, I don't know how to change the size of the control at run or design time, nor how to disable the user from changing it at design time.as a side note - I know that there are a few star rate controls already floating around the internet, but I do not like the quality of them (or at least the one's I've seen), they felt very windows 98. I'm trying to make something that will fit well into windows 7 (plus I want to implement custom images, but that can wait until I get it working)

I'm writing a custom control and I want to add a "MessageText" property of type String:
<Browsable(True),
DefaultValue(""),
Category("CustomControls"),
[code]....
The MessageText property is a multiline text, and the user must be able to set the text using the designer. The problem is that the designer doesn't allow to enter a newline directly for a string property.I want the same behaviour as the system TextBox's Text property, where you can click on the down arrow and write lines in the small text-editor that appears:How do I do that?

Note: I am using Visual Studio 2010 EXPRESS EDITION. I don't know if this matters for something like this, but I thought I should probably mention it.
