.NET Forum / .NET Framework / New Users / May 2004Default Property
Hello All, there was much talk about the fact that .NET doesn't support default properties for objects, meaning that if in VB6 i could have Textbox1 = "hello", in .NET i can do it only by refering explicitly to the property Textbox1.Text = "hello". why then some objects like DataRow still have default properties? dr.Item("ID") and dr("ID") both work fine and serve the same purpose and of course, my quesion is how to create a default property for my own classes? is it by including the Item property when i design my classes? or is there some other tricks? :) thank you, Levon You can create default properties using System.ComponentModel.DefaultPropertyAttribute. Av. > Hello All, > [quoted text clipped - 15 lines] > thank you, > Levon If you have indexed properties (or indexers in C#) which basically means more than 1 value in the property, then you can use Default properties. Avnroe shows you how to do it with an attribute http://www.knowdotnet.com/articles/properties2.html > Hello All, > [quoted text clipped - 15 lines] > thank you, > Levon Thank you guys, so, the name of Item property is just a convention? // levon > If you have indexed properties (or indexers in C#) which basically means > more than 1 value in the property, then you can use Default properties.

I'd recommend using Item though in most cases to be consistent. > Thank you guys, > [quoted text clipped - 26 lines] > > > thank you, > > > Levon Free MagazinesGet these publications absolutely FREE for up to 12 months.
