group:TypeConverter in a form property
dotnet windows forms designtime:
Hi all,
i´m doing a form to be Inherited, and inside it has a property that i create. that property is one class with several propertys ( simple ones integers and strings ) And in my Inherited form, the property appears there :D so far so good. but i need to edit it. so i have create an typeconverter, so that property to be explandable in design time. now the problems start. this property is similar to the font property, every time i change in the base form it changes in every derived form. except if the derived form has already changed that property. But in my class it not works like that. every time i change in the base form the other forms seems to be changed, but when i do some kind of modification in a derived form ( ex: move a button and save ) it saves the property with the parent values ? can someone help me ??? thks JSB
thks for the help.
Please see the zip file, i will try to explain the problem that i have.( that is a project that i have made ) so, let´s start. if you see i have a base form with a public property. (Public Property MyClassTest() As ClassTest ) ) that property is the problem now i have a second form called configuration form, which is a base form too, is inhrited from the frist base form. so in this form ( configuration form ) i will do the changes to the ihnrited property MyClassTest, i will set the color and the text. and now in the 3 form wich is the application form, i will have the same as the other 2 forms, but with one exception, i don not need to change the property MyClassTest, unless i need to changed it explicity but this is not the case. so when i change any thing in the 3 form (ex resize the form), VS will save the changes, including the values in that property. can you assist me ??? thks JSB [quoted text, click to view] "joeycalisay" <hcalisay@_spamkiller_codex-systems.com> wrote in message news:%23Bm4HMq$EHA.2600@TK2MSFTNGP09.phx.gbl... >> but when i do some kind of modification >> in a derived form ( ex: move a button and save ) it saves the property >> with the parent values ? > > You are having some problem with code generation.

hi there thks for the help.
i already understand the serializer but try to do one thing, perhaps you can see what i´m try todo. try this create a formBase the font property is ( Microsoft Sans Serif; 8,25pt..... ) after create another form inherited from the first and change the font property if you see the code there is an entry some thing like this Me.Font = New System.Drawing.Font("Microsoft Sans Serif", 9.25!, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, CType(0, Byte)) now create another form inherited from the 2 form. you will see in the property page, that the font has the same value as the previous form, and if you see the InitializeComponent method, you will see that is nothing written to change the font in form3. what i want to do is the same with my class. :) can you help me with the sample that i send to the news groups. thks JSB PS: i allready tried the serializer, it works in the 2 and 3 form very well ( it only writes the changed property ), but when i do the resize on the form3 it writes the changed property again. witch i don not need because it was changed by the form2 .. :( [quoted text, click to view] "joeycalisay" <hcalisay@_spamkiller_codex-systems.com> wrote in message news:eXI$eDu$EHA.1296@TK2MSFTNGP10.phx.gbl... > VS by default serializes all non-default values of the properties of the > components.

VS by default serializes all non-default values of the properties of the
components. And since you have not provided any default property values, any change on your Form1 (resizing will do) will force the Form Designer to re-serialize or generate the code (codegen) for all the non-default values of the components involved, in this case the form. Having a default value set for your properties will minimize the codes generated on the InitializeComponent of your Forms. With this, you can attain Visual Inheritance (which is very buggy IMO). This can be attained by attaching DefaultValueAttribute on simple properties or providing the Reset<propertyname> - and ShouldSerialize<propertyname> method pair as I've said earlier. This is clearly illustrated in Burke's article that I provided on my last post. Try to read it, it will help a lot. If it's still unclear after you've read the links, just re-post so we can help you further... -- Joey Calisay http://spaces.msn.com/members/joeycalisay/ [quoted text, click to view] "João Santa Bárbara" <joaosb@i24portugal.com> wrote in message news:u$6yAQt$EHA.1300@TK2MSFTNGP14.phx.gbl... > thks for the help. > > Please see the zip file, i will try to explain the problem that i have.( > that is a project that i have made ) > > so, let´s start. > > if you see i have a base form with a public property.
