[2008] Can A Form Be Used As A Custom Control
Jan 23, 2009This relates to WPF but is broad enough that a winform answer will do. I have made a few custom controls in the past by inheriting from whatever particular control I wish to inherent from.
I have noticed that I can add a form to a class/user control library from the add new dialog and have it run. When this application is compiled I get a DLL.
So my question is can I use a Form as a custom control. The reason I ask is I am creating a more advanced MsgBox for a new application I require and a form as its container makes the most sense.
VS 2008 Add A Custom User Control To A Form Or Project
Mar 19, 2009I'm coming over from VB6 in which you could use 'user controls' to create reusuable custom controls. They were simple and contained and you can easily create several instances of a user control within the same or other apps. In vb2008 there are user controls but I can not figure out how to add them to forms or or other apps. Can someone please give me the the basic steps to add a custom user control to a form or project.

View 3 RepliesWhy Does Form Crash When Change Custom Control
Jun 11, 2009I have created a custom control that is included in a control library that is referenced by a VB Forms application.
When I modify the control, and have the application open in a VS window, VS usually asks me if I want to reload items that have changed.
However, a couple of times, it has not asked me this, and when I go to open the form that contains the modified control, I get an error window warning me that if I ignore the error message and continue, then I risk making VS unstable. I've learned to ignore this error message, continue, and immediately save the form to a new file.

View 5 RepliesScrollbar On Custom Control (inherited From Windows.form)?
May 16, 2011I'm trying to create my own control to build a custom planning on it.After trying it with loose controls I got an error but after advice on my previous post, I redraw everything.I have now the header of the control finished, the header shows the days of the month for as many months that fit in the window.Now I want to put the list of data below it, but it will be more than the windows height, so I need to have a scroll bar that will scroll the data but not the header.I would not like to design my own scrollbar and rather use the scrollbar control for it, but when I put it in, I cannot use the NEW keyword.example:
Dim sb
As
ScrollBar
with this I get the error message: 'New' cannot be used on a class that is declared 'MustInherit'.How can I get a scrollbar on my form to scroll the list only (so not the header)?
Custom Control Losing Size Around Edge When Added To Form
Dec 7, 2011Having some issues with creating a simple control in vb.net.
I create a control with a single label in, I don't change anything except the colour of the control and the label and also making the label anchor to the edges ( with a small border around the edge)

as you can see in the second image the control has lost its white border at the right and bottom.
VS 2005 Delete/remove Custom Control From A Form Programmatically?
Feb 14, 2010I created a custom control and add it to a form programatically.
The user can add and move them all over the form.
The problem is when I want to clear the form of my user control I don't know how.
I created an array of my control called ctlCorkNotes
Say I create ctlCorkNotes(1) and now I want to delete it.
How do I do this so it is gone and would have to recreate it to show up again?

Sep 11, 2009In 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.

VS 2008 Custom Control Refresh
Jan 27, 2010I have several custom controls inside my project, just added a new class and then inherit the original control. For example i have a Custom DataGridView Control (CustDGV), that defines several properties in the constructor of the control.Now i have one problem and one issue, the problem, if i change the CustDGV i don't know why, the forms that are using the control doesn't update the changes... The only way it's removing and adding it again.. not very useful when i have several event's already defined for the dgv.How do i force the form to update the control?The issue it's that some of the properties doesn't get applied, for example i set the column header height and the disable resizing in the constructor, but if i run the code this two properties doesn't get applied, i need to define them in the form where i use the control to get the results that i expect..The order of the properties in the constructor? The properties in the properties window override the constructor ones?

View 1 RepliesVS 2008 Moving A Custom Control
Feb 1, 2010I have a panel that has 9 pictures boxes within it. I need the User to be able to create as many instances of this control as they like.
Then each control needs to be able to move freely within the form.
I've created the control and added the appropriate code to move it around the control.
I've made the control canvas the same size of the panel. The problem is that when I move the panel, it only moves within the bounds of the control canvas. I guess I could increase the size of the canvas, but then additional controls would still only be able to move within their bounds and it would come out all wrong.
Is there anything I could do about this? Or is there a better method?
VS 2008 Can't See Custom Control In VS Tool Box From Referenced DLL
Apr 14, 2010I have created a custom control in one VS project. Once tested and built, I then copied the object over to a structured class library type project I hope to use as a code repository for these kind of things. To ensure I can get to the control, I created a test project and added this repository dll as a reference. The problem is that I cannot see the custom control in the toolbox.
Is there an attribute or something I should've used in the repository dll in order for this to happen?
My objective is to create a custom namespace in this repository dll so that any custom objects or controls can be referenced in various other applications without having to copy the objects to each. I know my reference is good as I can create the control in code. I would just like to see it show up in the toolbox!
VS 2008 Centering Custom Control In Panel?
Dec 22, 2009I created a custom control and I'm trying to insert it into a panel, but also center it.The control itself is larger than the panel, so I've set the AutoScroll property of the panel to True. I think that might be affecting it. Perhaps I should just offset the Y axis a bit.But, either way, this is what I'm trying:
VB .NET
'Create the control
Dim AutomationReport As New AutomationReportControl

It works just fine with the X axis, but the control is out of bounds vertically. About 1-2 inches of the top is cut off.

VS 2008 - Custom Control 'Serializable' - Contains A List(Of Panel)
Nov 29, 2010I'm trying to create a custom control that contains a List(Of Panel). I quickly ran into an error about the base class Panel being nonserializable. So I created my own class that inherits from Panel and implemented the ISerializable interface. At the surface, everything appears to work, at least everything at design time. I don't know what would happen if I tried to run the application. Anyway, the errors occur when I try to open a file that contains my custom control. For example, I create a new Windows Form and add my custom control to it. I save the Form and close it.
Then I try to open the form and get the following error: Object of type 'MyTestApplication.SerializablePanel[]' cannot be converted to type 'MyTestApplication.SerializablePanel[]'.
I don't know what I'm doing wrong? I've opened the XML file to see what it's actually writing, and read the header notes about using binary base64 serialization. I think that's what I'm using, but I'm not sure.
Below is the code for the class SerializablePanel:
Imports System.Runtime.Serialization
Imports System.ComponentModel

VS 2008 Adding A New Method To A Custom Control Found
Feb 25, 2010I found a custom ListBox that, strangely doesn't have an InsertAt method and I would like to add one. The custom ListBox uses an object instead of just a list of strings like a normal ListBox. I was curious what the logic behind inserting a new item at a particular index would be.The only thing I could come up with was add the new ListBoxItem at the end, then using the specified index, I could either keep moving ListBoxItem objects to the bottom, with the Add() method, from that index till the ListBoxItem at that index equals the one added, or I could use that index number in a "calculation" till I know I've moved the correct number of objects.

VS 2008 Handling Exceptions In Custom Control Library
Oct 21, 2009So I've made this control that inherits from the treeview control and basically loads objects from active directory into a treeview (url...).All working fine, but as this is the first custom control I have made that I have intended for other people to use, I'm not quite sure how I should approach error handling.I mean, obviously I shouldnt do something like show any exceptions in a messagebox because that might not be what the person that is using the control wants to happen. So do I just write out exception messages to the debug window? Do I swallow exceptions (guessing not)? Do I just totally ignore them so that they are thrown in the user's project?
