Hi guys, I want to build a class either from Control or UserControl but I don't want to display it's parent properties (Control) inside the PropertyGrid control. I am wondering if there is any easir solution rather than just overriding the parent properties.
Thanks

Hi,
As far as I know, there's no easier way to do this. Also simply overriding isn't enough but you must also apply BrowsableAttribute.
If you are trying to make your own properties more easy to find in Properties window, you could use CategoryAttribute to create your own category where your properties are shown. But don't know if this is what you're trying to achieve.

Actually, I created my a custom button that is derived from the Button class. I just want to display properties that are only defined in my custom class. Currently, it shows all, offcourse.
It could have make my life very easir if there is a way to do.

What is the difficulty if all properties are shown? Finding only the ones you actually neeed (=your own properties)?

It's becuase, I do'nt want to display all the properties in my application. Let's say, you have a Rectangle class and it's has the following properties
Width, Height
Color
Name
So, why would you want to display all the Control properties inside the PropertyGrid.
Another way way i was thinking is to create a data class that olds only the properties and populate the my custom object through that class. And also assign that data class to the PropertyGrid.
The bigggest problem will be that for each (Control object) I will have a data class. So, by extending my above example. I created a Field, Player Control(FieldControl.cs, PlayerControl.cs) classes I'll have to have FieldDataClass.cs,PlayerDataClass.cs.
if so do you think this may be led me into problems?
I appreciated your answers. Thanks

You're welcome.

So is this actually a run-time problem, not design time? i.e. you're using property grid in your app to let user modify properties?

yes that's right. Is there any advice you would like to suggest for my design

Based on the info in your posts I would use data classes as you thought instead of controls directly. It keeps the solution more simple and maintainable. Also use inheritance wherever applicable along with interfaces. Especially if you have common logic based on properties using interfaces and extension methods could be powerful.

Hello,
I have two versions of a software (let's say, 1 and 2), and version 2 needs to import user settings from version 1, which is stored in the Isolated Storage. The two versions have different Strong Names, resulting in two different folders in the isolated storage.
How can I, in version 2 of the application, obtain access to the isolated storage of version 1?
I've found this method that seems hopeful,

However, I can't find any examples of how to create domainIdentity and assemblyIdentity objects.
Thank you for your time.

Anyone know how to disable a list item in a listbox control in C#?
I've seen some posts that say this isn't possible. Some people have posted that they have never seen this functionality in a lisbox control.
Visual FoxPro allows disabled list boxes, and I've seen this in other Windows apps, so it has to be possible.

What defines a disabled item?
For the item's appearance you can owner-draw the items.
For the item's state you could use an item class that keeps its
enabled state.
The sample code here[^] seems like a good start

Hi,
Since listbox items are objects they don't expose any special UI functionality. However the effect can be done by code by wiring SelectedIndexChanged-event and if the selected index should be handled as disabled, remove the selection.
However this isn't visual to the user since every item looks the same. There's no way of telling which is disabled and which isn't. Of course you can use owner drawn technique to make a different visualization, but that's not the only option.
What I would suggest is that you actually use ListView control instead. Since ListView contains ListViewItems, which are UI elements it's easier to control visual appearance by simply controlling Font and ForeColor. In ListView you also have to remove the selection when user clicks on an item. To do this, wire ItemActivate event and remove the selection if needed.
Hope this helps,
Mika

In my app, there is a control that can be customized, so, I am trying to use the collectionedtior in order to do it.
It works fine.
Now, I am in toruble trying to update the control. When the user closes the collectioneditor form, I would like to get this event, and then, update the control which was customized.
I know how I can get the object which contains all information which was entered by the user in order to customize the control. But I don't know how I can get the OK button click event or something else which indicates that everything was done, and the control can be updated.
How can I get this event, and so, fire a notifier in order to update the control?
Thank you in advance.

How do you invoke the collection editor form?

I am building an object in my domain that looks like this:
DeviceMonitor
..public int Id
..public int GetCurrentValue()
I created an object in my DAL that will load it up
DeviceMonitorDao
..public DeviceMonitor GetById(int)
Everytime I call DeviceMonitor.GetCurrentValue() it should return a frequently updated value in the database. How should I seperate this concern into the DAL so that I am not coding it directly into the the Domain object?
Thanks a lot,
George Mauer

The one that I started was using WPF with a humongous grid heirarchy with the use of gridlengthanimations (CP article). However, I have been so busy that I won't be able to complete it for the competition.

Hi, I have searched through the articles but I am afraid I still do not quite get the event handing (custom events) in C#. I am new to C#, but a VB programmer for some years.
I have a class:
public class GPErrorArgs : EventArgs
{
private string sAppVerData = "Global Parameters Class";
private int nErrorCode = 0;
private int nErrorSection = 0;
private string sMessage = "";
private string sRoutine = "";
private string sSource = "";
private bool bCritical = false;
private bool bMustDisplay = false;
public GPErrorArgs(string ApplicationData, int ErrorCode, int ErrorSection, string ErrorMessage, string RoutineName, string ErrorSource, bool Critical, bool MustDisplay)
{
sAppVerData = ApplicationData;
nErrorCode = ErrorCode;
nErrorSection = ErrorSection;
sMessage = ErrorMessage;
sRoutine = RoutineName;
sSource = ErrorSource;
bCritical = Critical;
bMustDisplay = MustDisplay;
}
Various gets left out here to shorten the code in this request
public string RoutineName
{
get
{
return sRoutine;
}
}
}
I have a class which wants to use the error handling thus:
public class CGeneralParameters : IDisposable
{
private string m_strConnectionString = "";
private string m_sAppData = "";
private bool m_bDoneBefore = false;
public event ClassErrorEventHandler RaiseClassError;
public CGeneralParameters()
{
try
{
EMCServerParams cConnect = new EMCServerParams();
m_strConnectionString = cConnect.DBConnectionString;
cConnect.Dispose();
m_sAppData = "Global Parameters Class";
}
catch (Exception ex)
{
GPErrorArgs e = new GPErrorArgs(m_sAppData, (int)EnumSets.DeskTopErrorsEnum.dteSQLGeneralConnectionFailure, 1, ex.Message, "General Parameters:Initialisation", ex.Source, true, true);
OnRaiseClassError(e);
}
}
protected virtual void OnRaiseClassError(GPErrorArgs e)
{
RaiseClassError(this, e);
}
public object GetParameterByID(EnumSets.UserParameterNumbersEnum ParameterID)
{
object ParamReturnValue;
ParamReturnValue = GetAParameterByID((int)ParameterID);
return ParamReturnValue;
}
}
What am I doing wrong???
