Use data. What is the correct way to do this?

[shapper]

Hello,

I have 10 labels in different parts of a page, each one displaying a
value.

I have a class that uses Linq to retrieve all those values from a
database and places them in its properties.

I don't want to create an instance of this class on each control init
event because I will be accessing the database 10 times.

What is the more correct way to call the data function once and fill
all labels?

Should I use a custom data source. How can I do that?

Thanks,

Miguel

You say you have a class which retrieves all the values...

So just instantiate the class and then populate the labels e.g.

MyClass myClass = new MyClass();
MyLabel1.Text = myClass.Value1.ToString();
MyLabel2.Text = myClass.Value2.ToString();

etc.

Should I use a custom data source. How can I do that?

Why do you need one...?
