I have created a usercontrol that contains two rectangle shapes to create a unique button effect and a rounded-corner rectangle shape serving as a border to provide a look similar to a group box. It also contains two labels, one for use with a Text property of the control and the other to indicate the status of expansion of the control. The control is designed to collapse itself when the "button" is clicked leaving only the "button" visible. Clicking it again toggles this affect. I've dubbed it an ExpansionBar. It is also designed to be a container control so that I can add controls to it and allow these to disappear when the bottom portion collapses. The problem is that the controls contained in this usercontrol cannot be accessed during runtime. In other words, I can add a checkbox to it and it will disappear correctly when the control collapses, but I can't select the checkbox to check it... same thing with any other controls, you can see, but can't touch. I'm a novice developer, so I'm sure I'm missing something obvious.

View 1 RepliesI've been building controls for many years professionally and personally, but even back in VB6 days I just could not work this out. After all this time I remembered about it again.If I create a usercontrol/containercontrol and add one or more controls to the controls surface, I just cannot figure out how to access the controls at design time.
View 4 RepliesI'm trying to test/debug a WPF UserControl library in Visual Studio 2010 with the User Control Test Container.exe. I keep getting the error "Assembly [...] doesn't contain any UserControls." This should be simple, and every msdn article and blog tutorial I've looked at suggests that it should all just work perfectly and magically.[code]Project File has debug options set to open UserControlTestContainer.exe, with ./MyTestLibrary.dll as a command-line arg.

View 3 RepliesI remember in VS 2005 that when I was working on making user controls, if I removed the default Form1 and ran debug, that some sort of test container popped up. The window had a drop down menu to the right with some other properties so that I could choose from it the control I wanted to test. Choosing it would show the control to the left (in the main area) so I could test it, all without placing the control(s) on a form.
However, I cant find how to use this in VS 2010. I tried deleting Form1 and leaving nothing but by custom controls, but it just causes errors.What is the name of this window, and how can I get to it in VS 2010?
Is there any way of adding a control to a container within a structure declaration in VB .NET?

View 3 RepliesHow do I check whether the controls in a usercontrol contain any value?
I have created a usercontrol called ctlCustomerAddress and I want to create an address record in the database if only I have the values in the textboxes.
am trying to make use of inheritance to keep consistency in my user control appearance. I created a usercontrol to use as my base design, as a platform to link to a tab as acontainer. To this I added a few framing visual items like a header panel andsome labels.I then created another usercontrol that inherits from my base control, with the intention of adding the necessary items to this derived control to build it into a complete functional usercontrol that I can associate with a tab on my main form. I want to keep the visual appearance consistent across all similar derived controls. Then later if I change the design of the base form, this flows through to the derived controls.
View 7 RepliesVB.NET 2.0 Framework..I developed a control that implements IExtenderProvider in order to attach to controls and display a form for translating of the text of that control.This works great on regular controls on the form but the IExtenderProvider is not attaching to controls on UserControls by default.Is it possible to modify the UserControl or my IExtenderProvider control to enable it to attach to controls on a UserControl?

View 12 RepliesI am trying to make a small control that has a picturebox and a few labels that can be dragged on the form it is placed on. The control was easy, and I can drag it fine when the mouse is down on the control, where there are no other controls, like not over the picturebox or labels.
When i try to click and drag the user-control and the mouse is on the picture box or labels of the control the mouse down event is not detected. I am hoping someone can tell me how to pass the mouse-down event from the controls on the user-control so the form I place it on detects the mouse down even no matter where on the control i click.

I have a Windows Form frmMain() holding seven more-or-less unrelated UserControls, ucFlopsy", "ucMopsy", "ucCottontail", etc...I say "more-or-less" because each of the seven UC has three similar public read/write properties:
IsLocked (a boolean indicating if the following two properties are "Locked")
IsLockedID (if IsLocked=True then IsLockedID is an integer)
IsLockedName (if IsLocked=True then IsLockedName is a string)

I have a Windows Form that contains a custom control container as a UserControl. For the sake of this question, this custom control container is called Dashboard. This container called Dashboard contains numerous other controls depending on their permissions. I need to raise events that are contained on these controls through the Dashboard control and over to the Windows Form.
How can I bubble up the event? I'm using VB.NET for this project, but can convert C# into VB.NET.Also, to complicate matters, the main Windows Form is a VB6 project. So, I'm using the InteropFormsToolkit to accomplish this.
I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.
I have a couple of tables in my DB that contain stored procedure names, control names, control types, SqlDbTypes, etc.... that correlate with DataEntryUC.
How do I reference a text box that is on DataEntryUC from NavSaveUC?
I have been working on the following code from NavSaveUC with no luck.
Dim MyControlName = "txtFirstName"
Dim MyControlType = "TextBox"
Dim MyStringValue as String

I have a usercontrol that has a main form and calls another form within the usercontrol to get some data from a database that allows the user to select some items from a CheckedListBox control on the sub form. I want to pass the selected items from the CheckedListBox back to the main form and display the results there. I have a public property called DBList of type List(of String) on the main user control. If I create a reference to the usercontrol form the second form within the usercontrol I get a new instance of a user control. All I want to do is set the property on the usercontrol and close the secondary form. How do I reference the usercontrol from the form within the usercontrol?
Code in UserControl:
Public Property DBItems() As List(Of String)
Get
Return DBItems

Probably a dumb question, but can you write a unit test project in one language to test against another project in a different language?I'd like to translate one of our VB assemblies into C#, but want to build unit tests to verify the results. I've tried to set a unit test project up to do this, but I can't seem to access the VB code within a unit test... I can't figure out if I'm just missing/doing something stupid, or it really isn't allowed.
View 2 RepliesI just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.
