VS 2010 User Control "Test Container"?
Dec 4, 2010
I 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?

I'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.

In a user control I have the code shown below.
I now realize that it is incorrect because the container's InitializeComponent property initializations have not run yet and they must be run prior to Refresh being called.
How (where) can I run Refreash after the container has initialized this user control.[cod]e...

I have a User Control which is dynamically placed by CodeBehind as follows:
Dim myControl As Control = CType(Page.LoadControl("~/Controls/mainMenu.ascx"), Control)
If InStr(Request.ServerVariables("url"), "/Login.aspx") <= 0 Then
mainMenu.Controls.Add(myControl)
End If
As per an example from my previous question on here.
Within this Control is a repeater which calls a database to generate values.
My Repeater mark-up is as follows
<asp:Repeater runat="server" ID="locationRepeater" OnItemDataBound="getQuestionCount">
<ItemTemplate>
[Code]....
The example above works fine, but I want to be able to prepend text to <%# Container.DataItem %> in the title attribute of that <p> to print to the browser like this is some text DATA_ITEM_OUTPUT
When I try to do that though, it prints this is some text <%# Container.DataItem %> exactly like that, ie, turning <%# Container.DataItem %> into text, NOT the value from the repeater code.
It was working fine before I made it into a dynamically inserted control, so I am thinking I might have something being generated in the wrong order, but given that it works without any prepended text

I'm not sure where I'm going wrong with this. it's supposed to let the user add scores to the list, then calculate the total, average, and count. However, it doesn't let me add more values to the list. Any help whatsoever would be awesome! Keep in mind, I am new to VB and programming languages, and was just playing around with code hoping for any sort of positive result, and therefore some of the code may not be necessary, or make sense. Here's what I have now:

Is there a way to draw in the foreground of a container control. Such as a Panel, or PictureBox.
I need to be able to draw across multiple controls all within the same container.
Lets say, that you have a Panel containing Five Buttons. Is there a way to draw say a line across all five buttons, that will show as a continuous line, using only the Graphics object of the container?
I can only get the line drawn in the background such that the controls are drawn over the line and it appears broken. In the actual usage there are 25 controls and I would rather not have to loop through each contorl and drawn the line if needed, every time the control is invalidated.

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.

A panel with enabled scrollbars has many buttons. If I push the tabulation key, focus navigates between buttons.When a partially visible button has focus, the panel scrolls itself in order to completely show the button.

I have a problem in VS2010 with a user control i have created, I wonder if this is a known problem and if there is a resolution.
My project has a root namespace of DEV2.MyApp.I have created a user control and dragged it onto my form at design time.In the designer i get an error for that form that goes like this:-
Type DEV2.MyApp.myCtrl is not defined Me.myCtrl = New DEV2.MyApp.myCtrl ()I correct it by removing the namespace DEV2. like follows.Me.myCtrl = New MyApp.myCtrl ()
However, everytime i make an amendment to this form on the designer, the error creeps back. Its really annoying and I dont really want to resort to having to create the control at run time to get around it.

I have a simple .NET 3.5 app for changing some database fields using an ODBCDataSet. Now the Feature Creep is asking if I can hide or show tabs and other controls based on the user's database permissions. Ideally, I would like to control the permissions only on the SQL Server using Windows user groups, and the app would not have any built-in authentication or permission system--it simply uses the logged-in user's Windows account for the database connection. So thus it would have to "test" the permissions to determine whether or not to show the tabs for the user. For example, if they have "write" permissions to a certain table, then the tab for editing it would be visible; if not, the tab never loads for them. How can I list or test the user's permissions to the ODBCDataSet?

I have a bit of a problem creating a user control at the moment. I'm creating it within my current project via the 'Project> Add User Control' menu item. The problem is that when I create the control, run a build and add it to my form the controls within the custom user control are about one and a half times the size they should be.

I have code for make the usercontrol transparent:
Protected Overrides ReadOnly Property CreateParams() As CreateParams
Get
Dim cp As CreateParams = MyBase.CreateParams
cp.ExStyle = cp.ExStyle Or &H20
'WS_EX_TRANSPARENT
[Code] ......
These code shows the usercontrol transparent. But when the control moves I see that these control needs time to be transparent or drawing an image. Why so many time(maybe 2 seconds)? And why I can't use directions keys on keydown event? (The arrow keys are ignored).

When I click the button I called the function and datasource binded to propertyyGrid, its working fine. The same way am binding the grid from another class.vb, the datasource binding not throwing any exception. But the data not showing in the grid. Should I need to change any modifier.

The call should cause a postback because I need the usercontrol to display the changes.I am currently trying to do it by using a linkbutton with style display:none, and calling its click event from the javascript function. But i dunno how to call the click event.

I am trying to implement a Web User Control into one of my APSX pages but keep getting the following warning:
Element 'IntFilter' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing.
The user control is defined in the same web project as the aspx page.
Question: How do I resolve this warning (I do not want to move the control to a separate project)? Also, what do I need to do to enable IntelliSense for this control so I can set its FilterTypeSelection property from ASPX?
Code for "~/FilterControls/IntFilter.ascx"
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="IntFilter.ascx.vb" Inherits="StaffSupport.Filters.IntegerFilter" %>
[Code]....
Also of note, if you drag the control from the Solution Explorer to the page in Design view it will add the references you need (though it was still generating the warning for me). If you drag it to the page in source view it will add an a tag with a href to the element.

I once saw in an app a control that allowed the user to choose when they wanted the Timer running. It looked something like this: And when the squares are green, for example Tuesday 3:15 AM - 4:15 AM, the timer would run during that time period. I'm curious as to what control will allow me to do something similar?

I figured it out. Check out the finished control [URL]..I'm trying to make myself a simple 'star rating' control.
It would have the properties:
StarCount (number of stars)
StarValue (number of stars highlighted)
I want to draw the stars using GDI+, have them highlight on mouse over, and change the StarValue when clicked.I have an idea on how to do this from experience with working with forms, but I'm having some difficulties with the Control development part. I couldn't find any tutorials which didn't inherit a control (such as a checkbox or button), and I have no idea how to make my control editable in the designer.
I think what I need to do is create StarCount as a property like this:
[Code]...
I also want to execute my drawing code at design time, so I can see the stars while laying out a form. as a side note to that, I don't know how to change the size of the control at run or design time, nor how to disable the user from changing it at design time.as a side note - I know that there are a few star rate controls already floating around the internet, but I do not like the quality of them (or at least the one's I've seen), they felt very windows 98. I'm trying to make something that will fit well into windows 7 (plus I want to implement custom images, but that can wait until I get it working)

this questions has be answered partially, but I can't find any full tutorial for this problem.I created my own user control (an advanced list with columns). Each column has different attributes like width, colour and text.I want to able to add this user control onto a form and select/edit the different attributes of each column. Hence, for each column in my user control (these columns are created beforehand, no columns can be added or removed from it) there should be a property in the property-menu. Each of these column-properties should be expanded (like the normal size-property in most default vb-controls that can be expanded with the little plus to show the width and height individually.What i mean by this, is: In the property-menu there should be attributes like Column1, Column2, Column3. Each of these attributes should be expanded to show the attributes like width or colour.
Currently I have different properties for different values of the same column, like Column1Wodth, Column1Colour, etc, but I want to group this under one value Column1.I think this is quite an easy solution, but forgive me, I spent more than 4 hours on google, but couldn't find a proper solution.

I was thinking I could do something like this:
