To display a list of strings in the property window of a custom control and to map the selected item of the list in the property window

I'm creating a custom control in ASP.NET suing C#.NET

The control has a property say Drive, that shows the list of all drives in the property window.

If I select any drive from the "Drive" Property of that control then how can i map the selected Item in the code behind.

public List allDrives = new List();

Public List Drive

{

get

{

return allDrives;

}

set

{

allDrives = value;

}

Now, this property of my custom control helps to load the list of drives in the "Drive" property and shows all the list of drives as a collection.

If I select any drive then there is another property that loads the list of directories in the another property

in that selected drive.
