I must have done something really, really dumb somewhere, but I don't know if I did a really, really dumb VB.Net thing or a really, really dumb Framework thing.I have a dirt simple UserControl - it consists of one Button. Nothing more.

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)

Is there a way to expose a UserControl's properties to the Properties Window in the Designer?
View 3 RepliesI 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

I am trying to develop a control that'll allow the developer to populate a collection through markup (e.g. Properties decorated with the attribute PersistenceMode(PersistenceMode.InnerProperty). I have an example from Brian Chavez that more or less does what I want but I want to have the control inherit from UserControl and not Control.Here is the code I have in vb.net:

As it is now when I try to compile I get a compiler error that simply says object instance not set to an instance of an object on the line above.

I'm trying to create a UserControl in ASP.NET to display news items based on two values that are passed in, NewsTag and ItemLimit.

View 2 RepliesIs there any simple way to hide all the design time properties of a User Control.
When my UC is on a form there's a lot of properties in the properties explorer. All those default ones that every UC has. AccessibleName, AccessibleRole, Anchor etc etc etc (dozens of the them)
Any way to hide most/all those and just expose my own ?
I suppose I want my User Control to be more like a 'Component' like the Timer and other components that don't have a UI. Short of rewriting my UC as a Component is there any quick way to hide all those form properties ?
Creating a usecontrol:
The control will have numberous properties available at design and run time.
I am having trouble creating and exposing FONT properties for the child objects.
Example: The control will have a label with a designtime and useradjustable Display font. I wish to
1) be able to set the Font attributes via the properties dialog at design time.
2) set those properties via GUI at runtime.
The problem...
Code:
Private propArtistHeaderFont() As Font
Public Property ArtistHeaderFont() As Font
Get
[Code].....
So clearly I can not pass the FONT properties back and forth via the SET/GET method.
I can create a Custom UserControl with simple properties (Integer, String, etc) and have those properties show up in the Property Panel. I can also create a Custom UserControl with properties like Size, Rectangle, etc and the properties will show up as an expandable item in the Property Panel (click on the '+' and the Size expands to Width & Height).
Is it possible to create properties with my own custom structure? e.g. Property 'Message' expands to Text, ForeColor, BackColor, Blink etc. I have tried creating a property that references a simple class or structure with containing the properties representing my custom structure but in the Property Panel the property is greyed out and cannot be expanded or modified.
[code]I want to make the Properties Window to update the properties for X and Y at each MouseMove, so they become immediately visible for the user.

I have a user control when a user change its width I also change its height by coding in a certain ratio. I also written some code in resize event of the user cotnrol . Now the problem is how to capture the resize event for height change only as it is running two times first when user change the width and second when height is changed from code .
View 2 RepliesI've been scouring the Net, but I can't find anything really useful on how to set a default button in a user control (everythings for ASP). I can imagine the brute force method of handling the keypress for each control within the control and checking to see if the Enter key was pressed, and if so, calling a PerformClick on my desired button... But I just have difficulty imagining that this will be the best method, especially on Search Controls that have 30-40 subControls on them. I've tried just handling the KeyPress event at the control level but it never gets called when a sub control has focus.
Another problem with the brute force method is that some of the controls within my UserControls are themselves UserControls containing several controls, so I would have to handle each sub control within the sub-user-controls and create EnterKeyPressed events that were raised when one of the sub-sub-controls received an Enter KeyPress. This could go on for several levels. Then I would need to handle all these events. This seems like an unnecessary layer of complexity.
Is there some way to create a routine that perhaps automates the above? Or just a simple workaround? I know I can set the Accept and Cancel Buttons of a form, but I have a form with a TabControl that has a UserControl on each tab. Each one of these tabs needs its own Default Button.
I have two UserControls already loaded how to change TextBox text property on a UserControl from the other loaded one.

View 7 RepliesI have a UserControl, we'll call it myUC, that is one among several UserControls in the main window(myWindow) of my WPF application. myUC contains a number of standard controls, one of them being a button, we'll call it myButton.
When I click myButton, I would like to execute myMethod, which exists in the code-behind of myWindow.
The problem being that myUC doesn't have any idea that myWindow even exists, much less that myMethod exists.
How can I send the message: 'Hey, myWindow, wake up. myButton on myUc was just clicked; run myMethod'?
I have a 'DataGrid' usercontrol on my simple little form and I press a button that opens a text file and populates the DataGrid like so,

Where A, B, and C are my column headers.
I also have a 'ListBox' on the form. What I would like to do is, allow the user to select one, two, or three rows (or all) in the datagrid, and press a button that will move the data from selected rows into my listbox (each row its own string in the list box).
I can populate the datagrib easy enough, but don't know how to access the cell data individually?
