Enum definition:
public enum Categories
{
Wildlife,
Resorts,
Beer,
Other
}
To tie to DropDownList called ddCategory:
ddCategory.DataSource = Enum.GetNames(typeof(Categories));
ddCategory.DataBind();
To set the selected value:
ddCategory.SelectedValue = Enum.GetName(typeof(grr.Categories),1) // or just "Wildlife"

This is how I do it...
public enum Categories
{
Wildlife = 0,
Resorts = 1,
Beer = 2,
Other = 3
}
To tie to DropDownList called comboBox1:
this.comboBox1.DataSource = Enum.GetValues( typeof(Categories) );
To Set a value
this.comboBox1.SelectedItem = Categories.Other;
You might also notice that I gave the enum some ids. I just find them helpfull, if I ever want to record a selection in a table somewhere.
@radical:
I am tying to the names and not values because to the user values may not make sense. Thanks for the comment!
Yeah but the thing about Enums is that once you assign them values, they can be easily interchanged. Number comparison is far more faster than string compare.
@radical:
I am sure you are aware than Enums are automatically assigned numbers in the order of 0,1,2.. if its not explicitly assigned. Plus I am not too sure of using enums for values that change!
I know... Don't get fooled by my simple example. My approach expands to enums having non sequential ID assignment.. You have a lot to learn my young padawan. :)
