VS 2008 - Custom Control Not Showing On Form In Design Mode
Jan 31, 2011
I have created a custom Combobox and added it to my toolbox, and it works well. Now I have added a custom ListBox to the same file as the combo box, but it does not show on my designer when I place it. I can however add it at runtime.
''ComboBox
<DefaultEvent("SelectedIndexChanged"), _
ToolboxBitmap(GetType(System.Windows.Forms.ComboBox))> _
Public Class ProjectsComboBox
Inherits ComboBox
''My Customization
[Code] .....
I have tried removing the "DefaultEvent..." and still no dice.

I have opened an existing project and made changes in the design mode. (For example, I added a new button.) But when I tested the program using Start Debugger, none of my changes showed up.

I am using Visual studio express 2008. I was working on a VB project for a few hours. Then I did something,(I think I just double clicked the form ) and I cannot open it in design mode. By Design mode I mean so you can see the controls, and ad buttons and stuff. The form still runs, if I run it. I see the form in the Solution explorer. From solution explorer, if I show all Files , then open FrmMain.Designer.vb, I can see my code. If I go to the project menu item and insert New Windows Form the new form works like I expect it too, I can see it. I need to be able to see my form.

I have a UserControl that contains other controls that I would like to be able to rearrange or resize at design time. So I have a custom designer for the UserControl that inherits from System.Windows.Forms.Design.ParentControlDesigner, and I call EnableDesignMode on the child controls from within the designer. That way, at design time, I can drag and drop the child controls to move them, or resize them. But I can also drag and drop the child controls somewhere else on the form that is outside of the original UserControl. Is there a way I can limit the child controls from being moved or resized outside the UserControl?

I have a document with VBA controls in it that I created in MS Word 2003. After migrating to MS Word 2007, I get the message that "Can't exit design mode because control 'lblEmaillist' can not be created".
After reading through the various forums here and on microsoft.com it seems to be a known problem. I looked at these articles but am still having a bit of trouble...
[URL] refers to the same problem in word 2000 but after following the directions I still am getting the problem.
The problem does not occur when I open the document in MS Word 2007 or MS Word 2003. The problem only occurs when I open click on the link from IE.
I've set up the location as a trusted location in Office 2007 settings so that should not be an issue.
The document in question is being saved in the word 97-2003 format due to the fact that some people here have not upgraded to office 2007. I tried saving it as a .docm for office 2007 but the error message still came up.

How can I basically lock a default property so the user cannot edit it? For example, if I wanted to lock the BackColor property, how can I make it so the end user of the control can't edit it?

When you INHERIT from TabControl to create a different version of the TabControl, then BUILD the designer will add 2 TabPagesby default when you add your new TabControl from the ToolBox to a Form.

I have a form-based application, that until recently displayed the controls on the form when in Design. For the last week or so, when I go to Design mode for the form, it is blank. However, the program does work correctly. And, I can see the control definitions in form.designer.vb. How can I get my form to display the controls again so I can add/move/change it going forward?

Every once in awhile when I double click on a form in design mode (Windows Forms Application) that contains a tab control, all of the controls on the tab control disappear. I have to reopen the form to get them all back. In addition to this, the column order of my columns on any datagrid inside a tab control get rearranged when this happens. Is this a known bug and if so is there a hot fix or patch?

I have a custom control that as a custom property. The property has several preset values to chose from a drop down. The control can be added to a form. The property can be viewed and set in the properties box in the IDE. It all works fine.
Here's the problem: I can create new versions and recompile the control and/or the application without the properties preset value being lost as long as I do it in Debug mode. However, once I try to recompile in Release mode the custom property values predefined setting is lost. I first thought it was something with going from debug mode to release mode. But it seems to be ANY time I recompile in Release mode the custom property values are lost. Is this a quirk in VS that needs a configuration setting, etc. to get around it?

setting the default value for an integer attribute of a custom control seems to have stopped working. The following code adds the Maximum attribute to the design-time properties table, but the default value pops up as 0, not 99:
<System.ComponentModel.Browsable(True)> _
<System.ComponentModel.Category("Behavior")> _
<System.ComponentModel.Description("highest value possible")> _

This 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.

I have a form where I have created a custom property, DataEntryRole, and set its Browsable attribute to True, as shown:
<Browsable(True)> _
Public Property DataEntryRole() As UserRole.PossibleRoles
Get
Return mDataEntryRole
End Get
[Code]...
When I view the designer for my form, DataEntryRole doesn't appear in the property box. I assume that it should appear if I were to create another form that inherited from this base form, but that's not what I want. I want this property to show up in my current form.

I'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.

I'm currently working on a treeview but want to add custom nodes at design time, is this possible?Also the treeview is part of a control, so i have created a control designer and added a custom design time form to add my custom nodes, but can't seem to get the nodes into the treeview in design time, and serialize into the form automatically?All my custom tree node is is an extra integer at the minute, but more properties will be added later if I can get this working.

why when I use My.Settings to Add items during design mode, they do not show up during run mode?
This is for a custom control.
I'm missing something between the control that exists on a Form during design-mode and the (apparently new) control that's created during run mode.
I can add items in design mode using the Application Settings editor (right-click on custom control, select Properties then Settings). But when I use code in a smart panel during design-mode along with My.Settings.MyProperty.Add() to add additional items, the new items show-up in design mode but revert back to the old set during run-mode.

I am using Visual Basic 2010 Express. I have a form with some text boxes on it. There was some code on that form which was giving errors. So I deleted the whole code. Now the problem is, I cannot see the form Design mode button to view it in design mode. But when I hit F5, I can see all the text boxes (in Run mode). I want to add some more controls on form. How to resolve this problem?

I accidentally deleted a tab in the design mode. I still have an old form in which the tab is present. But it is an old copy from the present project, hence is it not in the same project. What can I do best to get it back? By the way, Visual studio could better say some warning before they do that. And contr-z did not get all the content back. May-be I should have hit that button a few times more before I pressed save. I dont know.

Converted an VS 2003 VB Application to Visual Studio 2010. Conversion seemed to work great. Having trouble with the Backcolor of buttons. In design mode they are a light gray (I have them set to transperent and they are on a VBPowerPack.Blend Panel) - but in Runtime they turn the correct color (Steel Blue). How do I get design time to look the same as runtime? Also, they stay light grey in run time if I check Enable XP Styles. Makes me feel better to see the same colors at Design time
