Question

Create WinUserControl and use designer in Visual Studio

Asked by: Dnx_7

Hi experts

i just created a user control in Visual studio the component itself works fine but when i dropped in a new form
i have a property with "browsable" setted to false but i always get a bug in the designer :

Me.UcExAM.AlertManager = CType(resources.GetObject("UcExAM.AlertManager"), RVKernel.Process.AlertManager)
the property AlertManager is setted to false!!!  and why the designer created this line?

because of this line, the designer generated an error.


also, my second question is that the usercontrol use a DLL in the solution, this DLL is also used/referenced in the winform that used the usercontrol
each time i added the usercontrol, i always have to remove the DLL and add back to the winform project

Why?


Thank you,

Kind Regards.

BrowsableAttirbute only hides your property from the Properties window. In order to tell the designer to not generate the line for your property, you will need to use the DesignerSerializationVisibilityAttribute:

<Browsable(False), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> _
Public Property MyProperty As MyType
...

As to the second part of your question, why is it that you have to remove and add again this reference? What happens if you don't remove it?

 

by: Dnx_7Posted on 2009-08-13 at 08:24:24ID: 25089426

Nice !

The first problem is resolved thanks to your property :D

The second problem is that i have a lot of error (where i use any reference to this dll)
i have to remove and add again, that's strange

it's like the designer remove the existing one and add the one packaged with the component (even if it is the same)...


Regards.

The problem will be in the way you reference the DLL (assembly). Did you say this assembly is part of your solution? Make sure that you reference it everywhere through "project reference" and not directly as a file.

 

by: Dnx_7Posted on 2009-08-13 at 08:43:47ID: 25089670

Yes, that's for "sure" it is a reference problem
and yes, i use "project reference" when i add the dll

but when i use the component, drag drop in the form, seems that something happen with the dll while the component is created.

do i have to configure something?


regards.

 

by: BusacPosted on 2009-08-13 at 08:51:28ID: 25089773

The question is more of how the component references the DLL. Is the component also part of your solution? Does the project in which the component resides reference the DLL as a project reference?

 

by: Dnx_7Posted on 2009-08-13 at 08:53:39ID: 25089799

Yes

Everything is in the same solution.

eg :

projectWin (use library and component)
Library
Component (use library)

regards

 

by: BusacPosted on 2009-08-13 at 08:57:47ID: 25089862

In this case this shouldn't happen :P. I don't suppose you'd like to upload your code somewhere I could download it from? Or how about some very simplified version with minimum of proprietary code?

 

by: Dnx_7Posted on 2009-08-13 at 08:59:23ID: 25089886

No problem,

i will cleanup the code, test if it works after cleaning and if not, i will send u
