View 2 RepliesI have created 2 WPF control which reside in the same folder and i want to add one control to the other.

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'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 was trying to block the closing of a custom combo box popup window in my custom DataGrid. The popup window comes by pressing F4 or ALT+DOWN keys in my datagrid which is getting closed if I press the down arrow for the first time, after showing the first value in the combo box as selected. Next time onwards, if I press the F4 key and down arrow, I can move to any item in the popup window and select the item using keyboard and in that case, the popup window is not getting closed till I press the ENTER key or selection using the Mouse. Is there any specific reason for this behaviour or something is missing in my code part? [code]...

View 1 RepliesI'm an amateur programmer who's learned quite a bit from online references, and usually searching eventually reveals the problem but I'm stuck!I've overcome many obstacles when creating a custom button on the Ajax Editor control, namespace issues, registring the controls properly etc. I resist the temptation to ask for help because the errors should lead me in the right direction. Now I get no errors, but the control isn't visible! The tag is in the .ASP page and I even set the width, height and visible tags in case it's being hidden but nothing shows up.

I have been asked to build a custom wizard control in VB.NET for a windows forms project.

It has also been made clear to me that we are not "allowed" to use usercontrols in the software.

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 want to create a custom control based on the existing Panel Control with a property added called "transparent" which can be set to true or false. If it's set to true it's transparent(not invisible). So if I place it over some controls in a form say a button or text box... they are visible but disabled.

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?
View 6 RepliesI 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!
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.
