VS 2010 Creating A Custom User Control, Don't Know Where To Start?

Oct 26, 2011

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)

Creating A User Control At The Moment In 2010

Dec 26, 2011

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.

C# - Creating A Custom Start Menu Shortcut Link For A Visual Studio Setup Project

Feb 24, 2010

Is it possible to create a custom start menu shortcut link?

The only possibilities I see in the setup project are shortcuts to folders or primary output.

Update:

What I ended up doing is creating a custom action on commit that dynamically creates the link using Windows Scripting Host. Then on uninstall, removing the link.

Creating A Custom Control Box?

Dec 15, 2009

Is this possible? I am trying to create my own "X" and "minimize" buttons on my form -- the only way that I can currently think to do it is by making my form have no border, and creating a 'fake' menu bar using labels and buttons for minimizing and maximizing. The goal here is to be able to have custom icons for maximize, close, etc that may not match the Windows default scheme.

Embed A SilverLight Control In ASP.NET Control (user Or Custom)?

Apr 29, 2010

We have a ASP.NET web application written in VB.NET where we build content programmatically during the Init event.We make extensive use of user controls, building them on the fly, and I now want to start including SilverLight content.Is there an easy way of embedding a SilverLight application in a control, and then instantiating the whole thing in code, in the same way as you'd programmatically add ordinary ASP.NET controls to a page?The SilverLight component itself works fine when added to a page using the <object> tag but I really want to be able to reuse it elsewhere in code.Since I'm expecting use of SilverLight to increase in our application, and the asp:Silverlight control seems now to be deprecated, I'm looking for an alternative way of wrapping the content.

VS 2010 Creating Custom Controls?

Aug 23, 2010

I got this whole thing pretty well down (it's actually quite easy), but I've seen custom controls created where you can click that little arrow on the top-right corner and add things or change things about it.

How exactly is this done? I'd Google it (which is why you don't see me post here too often) but I really don't know how to describe it.

Custom Event In User Control

May 10, 2011

I've got a page (aspx) that contains a usercontrol (ascx).On postback of the aspx, I'd like to read some control values in the ascx. So upon reading some good articles, I created an event in my aspx that fires on postback.The event handler is in the ascx, and simply writes the values I'm interested in to the viewstate so that the parent page can read them.The problem is my event handler never gets hit, even though I see the event is raised as I step through the code. So my code bombs when trying to read the viewstate (which is empty)[code]Oh, did I happen to mention I'm dynamically loading the ascx? :)

I have a component class that inherits a user control class and i'm trying to inherit from that same class in a new class.public class B inherits class Unfortunately, I get an error pointing to the .g.vb file saying:Base class 'System.Windows.Controls.UserControl' specified for class '...' cannot be different from the base class '...' of one of its other partial types When I swap the "Inherits System.Windows.Controls.UserControl" with inherits from the base class in .vb files the program compiles but when I try to access any of the components I get an error saying "Object reference not set to an instance of an object."Why is it doing this? it's as if the my sub class isn't inheritingUserControl method at all.

Creating A User Control?

Dec 5, 2010

I'm coding an application that will work with many arrays of data. To make the code easier I want to make a user control (called Multiselect) that will include a textbox and a treeview. The textbox will be alway visible and treeview will appear when needed.The user will put a string in the textbox and the MultiSelect will search all of the stored data in a array that match the searched string. When done, the TreeView will appear and show the found items. User will have an opportunity to choose the right items through checkboxes.

What I can't do is the TreeView. I want it to act like the autocomplete in Visual Studio editor - for example you are in a class and type "me." and Visual Studio offers you all methods possible in a window. This windows doesnt get focus, but if on the top of the main form so the found items are visible over the text.

Custom User Control Graphics Rotation?

May 31, 2010

I'm trying to build a dial control as a custom user control in VB.NET. I'm using VS2008.so far I have managed to rotate image using graphics.rotatetransform . however, this rotate everything. Now I have a Bitmap for the dial which should stay stable and another Bitmap for the needle which I need to rotate.so far i've tried this:

Dim gL As Graphics = Graphics.FromImage(bmpLongNeedle)
gL.TranslateTransform(bmpLongNeedle.Width / 2, bmpLongNeedle.Height * 0.74)
gL.RotateTransform(angleLongNeedle)[code].....

As I understand it, the image of the needle should be rotated at angle "angleLongNeedle" although i'm placing the rotated image at 0,0. However, the result is that the Needle doesn't get drawn on the control.

Custom Progressbar As A User Control - Get The Ocx Or Dll File

Nov 13, 2010

I made a custom progressbar as a user control. And I have only been working with forms 'n classes. As you all know, when you create a component in class, it gives you the dll file for the custom component or whatever you made so you can use it on any program. On my custom progressbar, I don't know how to get the ocx or dll file so I can use it on my other programs. OR.. if this is even possible lol. If you could help me on this, that'd be great. And I don't know how to make a custom progressbar out of a class, only user control, so if you could teach me how to make a progressbar out of a class, then that'd be awesome too.

Shadowed Events In A Custom User Control?

Nov 11, 2009

I have created a base class for some user controls, then I created controls that inherit this class. This is so I can CTYPE the inherited controls back to the base class and refer to properties, methods and events in a common interface. The base class declares has some Public Event BLAH(Sender as object, e as EventArgs) declarations. The derived class then has Public Shadows Event BLAH(Sender as object, e as eventargs) declarations. My parent form adds handlers for the BLAH event. When the derived class fires the event, though, it does not get raised to the parent form.

User Control Custom Event Program

Jan 16, 2010

I had this new idea for a user control Sliding Bar/Panel. See screenshot. So I quickly whipped it up but I've got this problem that I cannot figure out why it does not work. Because I wanted to make it nice and tidy I desided to use a Class (Header) and created a TypeConverter (HeaderConverter)

Code:
Public Class HeaderConverter : Inherits ExpandableObjectConverter
Protected SortOrder() As String
Public Sub New()
SortOrder = New String() {"Text", "Depth"}
End Sub
[Code] .....
and goes to the RaiseEvent but nothing happens Why?

I know I could put properties on the Container control to access the ctnbutton Control that is embedded into the control but I thought this might be a nicer way.

Wpf - Fire A Custom Event From User Control?

Feb 10, 2012

I have a user control (SomeUserControl), that I am using in a Main Window. I write my application entirely on SomeUserControl, and Main Window is hosting SomeUserControl and nothing else.

Right now I have a shutdown button (in SomeUserControl), that is supposed to close the Main Window. The reason for this is that I do not want anything from SomeUserControl to close the application itself, but to fire an event from SomeUserControl, and Main Window receives it, and Main Window will close the application instead of SomeUserControl.

How do I do it? I am not familiar with the concept of creating and handling custom events, so if someone could explain it in words and in code as an example, I will be very grateful to you!

Edit: Here's my code so far.

(in Window 2)

Public Event CloseApp As EventHandler
Private Sub CancelButton_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles CancelButton.Click
DialogResult = False

[Code]....

I want to close the application when I click cancel in Window 2, but I don't want to do it in such a way that Window 2 closes itself, but by sending some notification to Main Window, and Main Window closes the application.

Creating Navigation User Control?

Feb 3, 2010

I am currently trying to create a generic navigation control with a similar style to the outlook navigation bar. I have figured out how I would be able to dynamically create the bottom part where you select the menu option, but I'm struggling to figure out how I would be able to create the top part, which can contain any user control that the developer would want.So basically what I'm trying to figure out is, is there a way to allow for a developer to add controls to a specific area of your user control?

If there is a way of achieving that then if anyone knows how to do this;In ASP.Net you have the login controls and with one of them, you are able to have different views depending on whether the user who is viewing the web page is logged in or not. Is there a way of achieving this in VB.Net for a user control that could be set up so that I could have the developer able to switch the view in the designer to show them the view for when a specific navigation option has been selected.

C# - Use ResolveUrl() To Set Some Paths In The Code Behind Of A Custom ASP.NET User Control?

Mar 31, 2010

I'm trying to use ResolveUrl() to set some paths in the code behind of a custom ASP.NET user control. The user control contains a navigation menu. I'm loading it on a page that's loading a master page.When I call ResolveUrl("~") in my user control it returns "~" instead of the root of the site. When I call it in a page I get the root path as expected. I've stepped through with the debugger and confirmed, ResolveUrl("~") returns "~" in my user control code behind.Is there some other way I should be calling the function in my user control code behind to get the root path of the site?
