Usercontrols - Properties Not Passing To From In .NET Custom Control?
Mar 6, 2012
I have a custom VB.NET control that I created that is working correctly in one program but not in another.The control has one button and one form. The form displays some data based on the settings in the control.
[Code]...
In TestProject1 - the control is working as expected In TestProject2 - the control is not sending any of the settings I set to the form My control works fine when I debug with the UserControl TestContainer.
I am using VB.NET on VS2005. This is all done on the same machine. Why would this work in one project and not another?
What I've done is create a User Control Library (Project) and I've added a single User Control to that project. The control contains a single FlowLayoutPanel, and I created a Property on the control itself to pass the FlowDirection from the Control to its FlowLayoutPanel child.
Build, reference, component appears in the Toolbox and everything works fine, but the property on the control does not appear in the Properties window when I go to edit it at design time.
In our IDE, for example, Visual Studio, if we display the properties of a System.Windows.Forms.Button control, we see some properties that expose anoter set of properties. For example: FlatAppearance, Font, Location, Margin, etcetera.I would like to do something similar in a custom control.I know the code behind is wrong, but here is an example of what I´m trying to do:
Public Class StateOfMyCustomControl Public Enum EnumVisibility Visible
[code]....
In my IDE, in the properties window of my custom control, I would like to see my property State, with the possibility of display it to set the properties Visibility and EventManagement.
I have built a Custom Control Class that makes it much easier to build a side bar element in my html.
The problem I am running into is that when I set the "Text" property, the last time I set it gets used for every instance of the control on my page. This is my first time doing this, so I'm assuming I'm missing something basic.
Is it possible to make a form that can set the properties on a custom control in the designer? What I mean is I want to know if it is possible to show a dialog that allows you to set the settings for a certain property like if you were adding items to a listbox.
This is similar to my last post but with a different purpose.I have built a custom control, but when I set the properties for it... ALL instances of that control on my page grab the exact same property. I need to be able to set the property to "abc" for one instance of the control on my page, and then set the exact same proprty to "xyz" for a different instance of the control on the same page.
I have a custom list control, using labels to display content.How can I add a list property to the control so I can inject items into the custom listbox?I know how to make properties for strings etc. but I can't get it to work to make a list property...
I have a custom control and have created some properties for it.When I click on that control, its properties are then shown in the PropertyGrid.The problem, is that I only want to show some of the predefined properties as well as my custom properties.Does anyone know how I can filter out the properties I want shown?
The project I'm working on (the same one I'm always asking about) has tabs as the main navigation. I've made some User Controls to sit above the tabs in an attempt to reduce the number of overall controls that are being used (to great success). Now, however, there's one control that overlaps some controls on a tab that are obscured by my newest UControl and I want to make the background transparent.I've seen that AtmaWeapon keeps pointing people to this page detailing how to make the background transparent. That's great and it worked for me. All I did was create the
Code:Protected Overrides ReadOnly Property CreateParams() AsSystem.Windows.Forms.CreateParamsand it worked the way I wanted. Yay. I did write the rest of it too as well as part from a post I saw on the msdn forums, but they weren't needed to get the effect I wanted.However, I've got a number of PictureBoxes on this UControl that should have a BorderStyle of "Fixed3D". However, when this UControl is repainted the borderstyle doesn't reflect this (Note to self: don't .Refresh() a control inside its own .Paint() event ). This doesn't happen the FIRST time they become visible, but only when they've shown up and are made to redraw (like toggling visibility). If the border changes programmatically they look fine
i've been trying to use customcontrols made in vb.net 2008 but when i try to add them to a vba form using
Dim x as new MyCustomControl.Usercontrol Me.Controls.Add(x)
it returns "activex can't create object" The control itself has nothing special, it's just random textboxes and a few buttons. why i can't use the control?
I've created a user control with a simple text box and a corresponding label and added a few custom control properties. When added to a form, I'm trying to loop through all control of this type and evaluate the custom property. In the below, the cntl.MyCustomProperty is not recognized. I can evaluate the property when I check each user control on the form by name, but not by using the loop below. I would much rather use the loop as it is much cleaner.
For Each cntl As Control In Me.Controls If (TypeOf cntl Is MyUserControl) And cntl.MyCustomProperty = "ABC" Then ''Do some stuff End If Next
I've created a Custom Control, and I will be placing a large number of instances of that Custom Control on my xaml page. In working with that Custom Control in the VB Code Behind, how do I do the following?
How do I reference the name of the Custom Control (in my VB code) which was clicked with the MouseLeftButtonDown event? For example, if I have 10 instances of my Custom Control in xaml, each with a different x:name (say 1-10), when a particular instance is clicked, how can I see which one was clicked? I've tried a number of things including e.OriginalSource.Name (which returns the component within the control which was clicked and not the name of the instance of the control). My Custom Control consists of numerous parts and pieces (Rectangles, Lines, Text, etc). Each of these items is a part of my layer. In VB code, once I can reference a particular Control, how can I hide or change certain parts of that control (such as hiding a Line, and changing the text). Also, I need to modify more than just the control which was clicked, so I need to be able to access properties of all of the controls, not just what was clicked. For example, if I click Control instance Test1, I also need to modify Test2, Test3, and Test5 in some way.
Here is some test code I through together as part of a Silverlight project using MS Blend 2. My control is much larger, and I need 200 - 250 instances/copies of that custom control, so I really need to know which control instance/copy was clicked.
I've populated a PropertyGrid with a custom class. How do you create and display a sub property similar to Size (Height, Width) which has two values or Point(X,Y)? For example, the class is Test and the property is Item as string. I want to expand Item to have two sub properties, A and B.
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.
I seem to be having a problem with controls that I am creating as new classes (not UserControls) inheriting from an existing system control. Everything seems ok while I create the control code, through to the compile (which is successful and adds the control to the toolbox) and dragging the control from the toolbox to the GUI surface. However, when I then debug or compile the project, I get a message such
I'm trying to create a UserControl in ASP.NET to display news items based on two values that are passed in, NewsTag and ItemLimit. The problem is that the SQLdatasource is not picking up the properties in SqlDataSource1_Init. Instead the calls to the properties are empty when this is called but after render have values.
<script runat="server"> Public Property NewsTag() As String Get
I'm making a control and I am trying to finalize my design time properties grid. I have several List(of Class) items as public properties and when I click on the design time menu (while testing the control) there is the word "Collection" and a button with an ellipsis (...) that brings up a neat pop up with the buttons Add/remove and all of the public properties of the collection's class on the right hand side. Basically for a non-collection instance of a class (with public properties) I'd like a similar button to show up. I know I could put all of the properties in the main control class and group them, but I like the pop up box feature. Anyway to duplicate this? (think font grid item etc.)
I have a class and method exposed to a client asp.net app. The class looks like
<DataContract()> _ Public Class Class1 Private v_string As String Private v_integer As Integer
[code]....
The method is declared as
<OperationContract()> _ Function GetStuff(ByVal bar As Class1) As String
In the client code I create an instance of Class1 and set the values for v_string and v_integer, but using Wireshark to look at the xml being sent to the server only a value for v_string is being sent as part of Class1. I'm guessing this is because it considers the value of v_integer to be null/not set. Here is an example of the client code.
Dim MyService as New Service1.ServiceClient Dim test as New Service1.Class1 test.P_integer = 1
[code]....
how different types are passed/used since Integer is a intergral type and String is a class, but can't seem to work out what to do to fix the problem.
how to specify a custom icon for display in the toolbox window when you create your own custom control? Something other than the dreaded "gearbox" icon.
I have my own class of graphic objects, and now I'd like to allow a user to right-click on one of those within the application and see a properties window. Is there a pre-built dialog or control for displaying properties at runtime? I'd like to have something just like the IDE properties window button for my application.
I need to implement some (maybe 10) custom properties for logged in users for my MVC3 vb.net web app. These will define how certain data is displayed within my views. I can think of a couple of possible solutions..
I was thinking to put attributes on BLL classes properties which ever are mandatory and I'm successfully able to retrieve the attributes also. But, not I also want to check the value of propeties. How I can do that:[code..]
I created a custom datagridview column for a progressbar and included customizable color properties but I can't get them to work right. After compiling, the properties show up correctly in the Edit Columns popup editor, but changing the values has no effectThe designer generated code shows the original values and manually changing them there has the desired effect(I know you're not supposed to, just testing). Here is the code for the column even though I don't think the issue is stemming from any coding errors there.
I'd like to add some custom properties to the columns of my DataGridView control. I'm not sure how to do it.I tried this once before but never got it finished. Basically, I'm making a teacher gradebook. Fore each column, I need to add properties called Assignment,DateAssigned, DateDue, PerfectScore, AssignmentType, etc.
I have developed a Windows service application in VB.NET.My need is to have custom property tab like "General", "Log On", "Recovery", and "Dependencies". Because I need to configure my service and also want to display some extra information in that extra tab.
