what i am trying to do is create a custom user control for my WPF forms that is a button with both text and an image. Everything that i have found is using C# and i am using vb.net.
View 4 RepliesI 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)
as in VB2008 the documentation suggest creating a module or class, then selecting 'Export Template' on the File menu. Regrettably my file menu does not show the item 'Export Template' in my installation of Visual Studio 2010 Beta 2.
View 4 RepliesI know this is really picky, but can I have one template inside a user control:
<uc:MyUserControl runat="server" ID="test">
<div><b>Test</b></div>
<asp:PlaceHolder runat="server" id="pH" />
</uc:MyUserControl>
Instead of what I have now which requires me to:

I want my User Control to be able to have Literal Content inside of it. For Example:
<fc:Text runat="server">Please enter your login information:</fc:Text>
Currently the code for my user control is:
<ParseChildren(True, "Content")> _
Partial Public Class ctrFormText
Inherits UserControl[code]..............
And when I put text inside this control (like above) i get this error: Parser Error Message: Literal content ('Please enter your login information to access CKMS:') is not allowed within a 'System.Collections.ArrayList'.This control could have other content than just the text, so making the Content property an attribute will not solve my problem.I found in some places that I need to implement a ControlBuilder Class, along with another class that implements IParserAccessor.Anyway I just want my default "Content" property to have all types of controls allowed in it, both literal and actual controls.
I am working on a project and I want to have a list box with a custom data template populate with user data. My question is, when I click on an item in the list box, how can I tell what item I selected? Basically, if I select "kevin", I want to display his data. If I select Dave, I want to display his data. I do not know how to get the data our after it is bound...
View 4 RepliesIs 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.
View 1 Replieswant to create a custom control of the button such as the button will be a bit enlarged and with a different colour.A custom control is a class that either inherits the Control class directly or some other control.So Iadded class named class1.vb and added this line:Inherits System.Windows.Forms.Button
View 6 RepliesI have created a custom control that has a few labels and a button on it. In my main program i dyanmically add this control to a stackpanel. When i add the control i add a few events for it by doing th e following:
Dim newqueue As New UserControl1
AddHandler newqueue.MouseDoubleClick, AddressOf PrintMessage
How would i go about adding an event for the button.click for the button in the custom control?
I did try to build a custom control but unfortunately i couldn't make it work due to lack of knowledge.I wanted to build an custom itemlist that allowed me to add 2 or 3 icons beneath it with labels associated.

View 4 RepliesWe 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.

I'm creating a custom control which inherets the BindingNavigator.I need do add one ToolStripButton at specific posistion (9 element) on the ToolStrip of the BindingNavigator.So, I wrote the following code:

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? :)
View 2 RepliesI 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.
View 2 RepliesI'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.
I have created a custom logonui.exe in VB.NET and I know how to make it replace the existing logonui.exe, but I am having trouble with the functions, such as shutdown, restart and log in. I don't need to get the list of users, because there is only one user account on the system and it is not password protected. I just need it to log in to the account when the user clicks a button and to be able to shutdown when the user clicks a different button.
View 15 RepliesI would like to recreate the behaviour of a button or command button on an user control. I need to layout a group of this user control on a form so user can select only one at a time. When users click on one of this user controls a selection frame is drawn to indicate that it has been selected. The problem I have is clearing the selection frame when other control is clicked on. How do buttons or command buttons do this? If you layout a group of buttons only one is highlighted. I have tried using different events like LostFocus and Leave and nothing seems to work.
View 3 RepliesI'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.
I created a custom user control named "XYZ" and It is avaialble at the toolbox menu in the design mode and I can drag and drop it to a vb.net Windows form. What I really want is to dynamically to add this user control to the Windows form during the Windows form load event. Actually I want to add this user control to a "split container" named "sc_1" on the tab page named "tp_1" on a tab control named "tc_1" on a Windows form. What is teh vb code to add a user control to a Windows form. I am using vs 2005 and dotnetwork v2.0.
View 3 RepliesI 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.

How to expose Events
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.
View 1 RepliesI 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.
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.
I want to understand N-tier architecture like when to use and so on.Also I would like to know about user control and custom control.
View 4 RepliesI 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.
How dow I create a user control for use in a webpage using VB.NET (not ASP.NET)?
How do I use that control in a webpage?
Can my control cause an event in the webpage and how? Ie. my user control has a button, and I want a Javsascript script to run when i click the button
I have followed the directions from this web site and the control works on a new form. But I have now written my own User Control. It compiles, I have changed Active Config within the Solution Properties to Release | Any CPU and built the Solution. But I can not find the .dll within the .NET framework Components after selecting Choose Toolbox Items from the Tools menu.
