.net - Group Properties In A Custom Control?
Apr 16, 2009
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.

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.

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 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?

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.
My UserControl:
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
[Code].....

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 have 53 text boxes in my windows forms application. I need to save the "text" of all the textboxes into a single file. Is there a way, I can control all the textboxes as a single textbox group and use its properties.
For example: Can I write something like :
For i As Integer = 0 to 52
Textboxgroup.text = TextBox(i).Text
Next

I spent a lot of time on this problem. I am able to do simple Group By LINQ queries (on one property) but for multiple fields I'm a little stuck... Here is a LINQPad sample of what I want to do :
dim lFinal={new with {.Year=2010, .Month=6, .Value1=0, .Value2=0},
new with {.Year=2010, .Month=6, .Value1=2, .Value2=1},
new with {.Year=2010, .Month=7, .Value1=3, .Value2=4},

I have a database.
Date-------------Amount
04/01/2009 ----- 1000
04/03/2009 ----- 2000
04/03/2009 ----- 2500
Now the problem with the Group Query is that I want to display:
Date -------------- Sum(Amount)
04/01/2009 ------ 1000
04/02/2009 ------ 0
04/03/2009 ------ 4500
As you can see that '04/02/2009' is not in database but I want to group by date daily even if it is not present in database....

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.)

So I've created a custom ListView by inheriting it and overriding the OnDrawSubItem(). I can now draw icons in several of the columns. It's pretty nice! My question is, is there anyway to do this for the ListViewGroup? I'd like to place an icon just before the group text.

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 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.
Imports System.Drawing
Imports System.ComponentModel
Imports System.Drawing.Drawing2D
