Asp.net - New Asp "showat" Attribute Required Inconsistently In VS2010?

Apr 1, 2010

When I generate code using T4 templates in Visual Studio 2010, I get the following error for each of my asp controls when I try to compile: Control "ddState" is missing required attribute "showat".

I have never gotten this error in previous versions of .NET. Further, I don't get this error when I manually construct my pages either by dragging/dropping, nor do I get it when I type out the control text myself. When I generate code, I have to manually add showat="client" to my tag for the compiler to be happy. It was my understanding that I never had to explicitly specify this tag. The following:

<asp:dropdownlist id="ddState" runat="server" showat="client" />

solves the problem. Why do I have to add this to generated code but not other times?

(It's a VS-2010 webforms project, using VB, in case that makes a difference.)

Cannot Load .rptproj In Vs2010?

Aug 2, 2010

I cannot load my solution which includes a .RPTPROJ for the reports development.

The .RPTPROJ project is not recognized.Does anyone know why? And please don't say "It doesn't because it is not supported".

If it is not then Why?Are we to wait for the next SQL release? Isnt there a plugin to support .rptproj?

Apparently i need to run vs2005 (or 2008) to support the reports while running vs2010 for program development.

Is there already a plugin or patch? Does vs 2010 (vb.net) support the report viewer object?

Does vs 2010 (vb.net) even support .rdl files?

I am developing against sql server 2005 as this is the clients version.

Create A UserControl Under VS2010?

Mar 23, 2012

I am trying to create a UserControl in VB.net, under VS2010. I have the code for the UserControl and I would like to add it to a form. My problem is that, according to every book and forum I have seen, after I build the UserControl, it should show up in the Toolbox. It doesn't. I even downloaded code from a book, the code executes perfectly, but their TrafficLight control doesn't go in the Toolbox (even though the book says it should - and that the only way to set its properties and to add it to the form is through the Control properties). I have tried to add the control to the form manually, by declaring it

Dim myObj As New SomeClass.SomeControl

and in the Designer.vb, identical with the buttons on the form:

Friend WithEvents myObj As SomeClass.SomeControl

With both, I get an error saying

'myObj' is already declared as 'Friend WithEvents myObj As SomeControl' in this class.

And either way, I get an error when I try to look at the design:

Could not find type 'SomeClass.SomeControl'. make sure that the assembly that contains this type is referenced. If this type is part of your development project, make sure the project has been successfully built using settings for your current platform or AnyCPU.


The control by itself builds and shows up in design view (not in the Toolbox though, even though it Imports System.ComponentModel and Inherits System.Windows.Forms.UserControl and... what else ? I tried to build it in a separate project, to see if I creating a separate dll will make a difference, though I really want it in the same project.
