I'm developing a program with a team in Visual Basic 2010.
What i wanna do is to create a textbox (inherits from textbox) with additional one property called MDIStatusInformation which is used to display a tooltip text in a status bar at main MDI form.
When i use this tag <Browsable(True)> _, the control property not list anything there.
Is it possible to create a user control with a list of custom class type property? If it is, how can I? The issue is that, in designer mode the property is not displayed in property window. I can add the list on markup but when i switch to the designer mode it gives an error which is 'The user control does not have a public property named BookList'.

View 1 RepliesI have an aspx page that has two different user controls. I want to find user control A and be able to set properties, etc., from user control B.
I was thinking I could do something like this:
Dim CMFilters As Control = Me.Parent.FindControl("CMFilters")
...but that doesnt work to be able to set properties and call methods. I somehow need to get the user control and and declare it as that user control type.

View 3 RepliesI'm building an control interface for a system that consists of 1-4 modules. In my interface, each module has its own control set, grouped in a groupbox. I only want to show the control groups for the modules that are actually connected and hide the rest.
This is easy to do with the visble property.
I also want all of the groups to be stacked vertically in the UI such that when one is hidden, the rest below it shift up into its place as if you deleted a row in a table. It needs to be able to come back just as easily.

View 5 RepliesI want to add a List(Of Book) property to my user control. I defined a Book class and BookCollectionEditor class for CollectionEditor. And also I defined a public property named BookList for my user control. For a custom control it works fine but for user control, the designer does not display my property. On markup I can add a Book item but on designer it gives error: "Type 'System.Web.UI.UserControl' does not have a public property named 'BookList'."Isn't is possible to define a list property for a user control?

When I try to create an Inherited User Control everything goes fine until I specify the base control and press "Add" in the Inheritance dialog. The code in the newly created Control should have a "Inherited From" statement, but it doesn't and nothing works after that. I even tried following the ctlClocklib project and the same thing happened. ctlAlarmClock.vb was created but the "Inherited From" statement was missing.

View 5 RepliesI want to create a User-Control that inherits the functionality of a TabContol.
I begin by starting a new project of the type Windows Form Control Library. Next I place a TabControl on the UserControl designer surface and Dock the TabContol to Fill the UserControl.

Inherits System.Windows.Form.TabControl
