Net Property Grid. Is There A Way To Let The Grid Manipulate Object In Different Way
May 31, 2009As I understood , The property grid is given an object which it can manipulate by extracting its Properties using reflections.
My problem is that I have a set of Parameters that is determined during run-time , thus I can't staticly compose a class with properties to represent this set.
I have two idea in mind to solve this problem but both are complex and will probably consume lot of time , infact i will say they are not practical under my time constraints. One is to use Reflection Emit in order to define a class dynamically and the other is to dynamiclly build a C# source file and then compile it using CodeDom.
Can Property grid behave in a different manner( other then extracting the Properties of an object using reflections ) that can suite my problem?
I want to say that the reason I went to the property grid from the begining was its ability to provide realy nice Data Retrieval UI for common types.For color you autometically get a palette , For dataTime you automatically have a nice calender. I would like to get those things automatically If possible.
VS 2008 - Property Grid - Click On Item Show Its Property
Mar 18, 2009I have a listbox with several list items added. I want that as user click on an item, I should be able to show its property. This should change for different items. For example (hypothetical) : Listbox has numbers 1 - 10. Now when I select 1 I should be able to set property - Name, Lastname, Colour, Age.
When I select 2 I should be able to set - Age, Hair Colour (clr shows), Weight, Date. When I select 3 then - City (combo box drop down), Country, Age only. This way value changes for diff items. One way is to put them in property grid and show them. Though this looks nice but adding/removing items in that is not easy. You need to have a class that refer that to prop grid. Do I have to code for each classes for all values in listbox or is there an easier way to manage items in property grid. If you think prop grid is not the right tool for such an activity then can you suggest something else.

Combo Box And A Property Grid In A Form?
Dec 15, 2011I have a combo box and a property grid in a form. The combo box contains 2 items. If one item is selected, two properties are listed in the property grid. These properties should have a dropdown that contains a list of items. I have two string arrays that contain the values for these properties. Can I use one TypeConverter that inherits StringConverter for these lists to be displayed in two different properties? That is, with one TypeConverter class, can I populate both the lists? I will also have to do the same with the other items in the combo box.
View 2 RepliesProperty Grid Collapsable Sections
Sep 20, 2010The only thing I am coming up with in my searches is stuff to do with expandable type converters, and all of that documentation is a bit over my head as trying all the examples is failing horribly. I would assume that there is an easier way to go about this without junking up my code with more stuff I don't understand.[code]Now, variables 1-5 have to go under section1, which is what is going on now. However, I want to group together variables 1-4, then group together variables 5-8, so they have the plus sign and can expand. But I cannot apply another category to any of these as they already have a category. All of the other things I have tried putting in additional "<tryexpand("notgonnawork")> _" sections does exactly that, not gonna work.

VS 2008 Flag Enums In Property Grid
Jul 10, 2009I have a flags enumeration property that I need to show in a property grid: [Code] In the property grid however, it only allows me to select a single value. I cannot combine the values like usual in a flags enum. How do I show something like a checked listbox in the property grid, so that the user can combine flags by checking items? A None and All item would be great but not required. [url]
But even that does not work properly. It seems to check and uncheck items arbitrarily. If you check the first and fourth item for example, the second and third items will sometimes be checked too. Yes, I realize that is supposed to happen with the TestEnum property (as that defines 'BottomRight' as 'Bottom Or Right', so that's logical), but it also happens with the SecurityFlags for example, which it shouldn't.

C# - Add A Service To The Type Descriptor Context Of A Property Grid In .Net?
Apr 13, 2010I have an app that allows the user to choose an image, at design time, either as a straight image, or from an image list.
All cool so far, except that this is not happening from the visual studio property browser, its happening from a property grid that is a part of a type editor.
My problem is, both the image picker (actually resource picker), and the imagelist type converter rely on some design-time services to get the job done. In the case of imagelist, its the IReferenceService and in the case of the resource picker its a service called _DTE.
In the first instance of an edit from the visual studio property browser, I could get a reference to these services but (1) how can I add them to the type descriptor context of my property grid?
It would be better, for future proofing, if I could just copy a reference to all of the services in the type descriptor context. (2) Where does the property browser get these services from in the first place?
ETA: I still don't know how to do it, but I now know it is possible.
(1) Sub-class control and add a property whose type is an array of buttons.
(2) Add it to a form.
(3) Select the new control on the design service and edit the new property in the property browser.
(4) The collection editor dialog pops-up
(5) Add a button
(6) Edit image and image list - the type editor and type converter, respectively, behave as they should.
ETA2: Ok, I'm getting warm. It looks like you do it through the Site property of the property grid. I can create a new site, and pass it the type descriptor context I have a reference to and then it should have all the service. I'll give it a go ...
Setting Property Of A Data Grid View Control?
Nov 15, 2010I am using VB 2008...
On my form I have a "Combobox1" that pulls a list from an access table. I also have a "DataGridView1" that pulls data from another access table.
I am trying to set the "DataSource" property of the "DataGridView1" after clicking a button, which pulls the "Text" property from the "ComboBox1".
ComboBox1.Text will always equal DataGridView1.DataSource as a text string.
I researched the Get/Set command, but it does not make sense to my specific application. I have read countless articles online for weeks, but I have now taken the next step.
Showing Properties Of Child Objects In The Property Grid?
Mar 9, 2010I have a custom class (Class1) with a bunch of properties. One of the properties of this class is another custom class (Class2) with its own properties.I have a property grid with the selected object set to Class 1. I can see Class 2 as a property, but i would like to expand Class 2 to show its properties in the same property grid.
Im basically trying to do the exact same thing as the Font Class on a form. If you look at the properties of a form in the designer, you can see the font property. You can then expand that to show the properties of the font class.

VS 2008 Properties In 'groups' (class) In Designer (property Grid)?
Jul 29, 2009I'm creating a UserControl that draws a simple radial gauge. I need it to be very customizable; the user should be able to customize everything such as the colors, fonts, sizes. So, I just made a property for every customizable detail. For example, I had ScaleFont, ScaleColor, ScaleStart, ScaleEnd, ScaleInnerRadius, ScaleOuterRadius, ScaleTickmarkFrequenty, etc.. etc.. etc...
Because there are so many properties about the same subject, I wanted to 'group' these properties into one "property". I've seen this done loads of times in third party controls, but I've never done it before myself.The idea is that the properties can be accessed like
Me.Gauge1.ScaleSettings.Start = 10
Me.Gauge1.ScaleSettings.End = 80
...
So far, I tried creating a class for each group, for example a clsScaleSettings class, containing properties like Font, Color, Start, End, InnerRadius, OuterRadius, TickmarkFrequenty, etc (corresponding to the same properties as above).
Then, for every 'group' or class, I create a Property. For example, I have the ScaleSettings property, which simply returns an instance of the clsScaleSettings class (I initialize the instance only once of course):
vb.net
Private _ScaleSettings As New clsScaleSettings
Public Property ScaleSettings() As clsScaleSettings
[code]....
Now, this works in the code editor. I can now use
Gauge1.ScaleSettings.Font = Me.Font
for example, and it sets the font correctly.But, I does not work in the designer, in the Property Grid. The whole reason I made the effort to move and rename nearly all properties (about 70!), and all references to those properties, to separate classes, was so that the user could design the gauge more easily using the Property Grid!Instead of having 15 settings related to the scale, scattered all over the Property Grid, he can now have one ScaleSettings property, which he can expand, and then he can edit the properties of that group easily.The ScaleSettings property is greyed out in the property grid... So I cannot expand it and view it's underlying properties.
WinForms - Editing Custom Readonly Collection In Property Grid
Feb 19, 2010I have a custom collection, lets says COL, that derives from ObjectModel.Collection. I have my own collection editor that works fine when a property, of type COL, is Read and Write enabled. However, if I change the property to ReadOnly, the open editor button stops showing in the property grid. As a test, I override my custom editor with the CollectionEditor, and that worked fine. So, my question is, what check is the property grid making, that CollectionEditor passes but my collection editor fails?
View 2 RepliesC# - Refresh Property Grid, At Design-time, When A Readonly Collection Changes In .Net, Winforms?
Mar 3, 2010I have a class that has a readonly collection property - Its a list of extender providers that have been applied to the control.I've implemented a simple property descriptor for the collection so that the property can be expanded in the property grid to examine each entry.
When I select an extender provider and set it to false, I remove it from the collection. The GetProperties method of the type converter is requeried and the property grid refreshes.However, when I set an extender provider to true, and thus add it to the collection, GetProperties is not requeried.
Somehow, the property grid is making a distinction between adding to and removing from the collection. Or alternativly, its refreshing when an extender provider is added, but not when one is removed.

View 3 RepliesC# - RefreshProperties Attribute At Class Level In .net, Winforms + Incorrectly Refreshing Property Grid?
Feb 15, 2010I had a strange problem editing a class in the property grid whereby the property grid would refresh incorrectly.I managed to reduce the problem down to a class with just two properties. I've included the code at the end to ease explanation.It basically boils down to a class with two properties. The first of which is expandable (a font)The class itself is expandable and also implements the CreateInstance method in the type converter.To see the problem, expand the font, edit, say 'Bold', and tab away. Two problems happen:
(1) The second property jumps up and ends up in the expanded font property.
(2) The '-' sign of the expanded font changes to a '+'.
The problem goes away by attaching ResfreshProperties(RefreshProperties.All) to the class. That's great, but I'd like to understand how it fixed the problem. I've had a look in reflector and can't find any examples of RefreshProperties being attached at the class level.

SQL Data Access: VB2008 / VB2010 - WinForms - Create A Datasourse And Drag / Drop Fields Or Tables On A Form To Create A Grid
Oct 22, 2010I have used VB (versions 2 - 6) through many years; however, I am crash-course training myself into the VB2008 / VB2010 world kicking a screaming. I would like suggestions as to what SQL database access method should I focus more on in my learning process without making me feel that I'm a million years behind. I know I have WinForms where I can create a datasourse and drag / drop fields or tables on a form to create a grid (not really what I'm looking for).
My trouble isn't so much designing the form but in how I access the database. Theres XML, LINQ to SQL, ADO.NET, and many other methods. Not only do I need to grasp these methods quickly but I also need to know what type of projects I should create. What I mean is...I was thinking that I would design a WinForm app; however, I see that there are WPF apps and others to chose from. This is getting deep. I know it depends on the project that I'm working on. My plans are to write an app based off of either an SQL Express 2008 or SQL Server 2008 database. This first app will be standalone for now but may later become multi-user. I know I'm far behind on my learning curve coming from VB6. I have read a bit on VB2005 / 2008 / 2010. I own
both VB2008 and VB2010. I use VB2008 at work. I know ADO.NET is still alive but by what I read online, it's a dying method and is only kept for backward compatibility. XML and LINQ to SQL and other methods are all pretty new to me.
Exit Grid With Ctrl-TAB When Grid Is On A Tabpage (onkeydown Works When Grid Not On Tabpage)?
Jun 2, 2010winforms .net 3.5 Ultrawingrid 9.2 In my subclass of Ultrawingrid.Ultragrid :
[Code]...
This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.
