I don't do ASP.NET all the time, so I haven't had a close look into what .NET 2 may change in this regard, though.

The GetItemProperties() method does not get called. Is this a problem with the DataGrid control? Thanks! Orlin Hi Oliver,

I implemented ITypedList in a custom collection as you described but although it works OK with WindowsForms GridView control, the ASP.NET DataGrid control ignores it. The GetItemProperties() method does not get called.
Is this a problem with the DataGrid control?

Thanks!
Orlin

Why would you assume that the properties should be in any specific order? Anyhow, I have some code that solves this problem and I'm going to put up another post today showing how it can be done.

The TypeDescriptor.GetProperties(MyType) line of code returns an array of property descriptors for "MyType"- but it seems that it does not always return the property descriptors in the same order as they appear in the class. Consequently, the properties can display in the grid out of order. Any ideas on why this is or how to get around it?
