If you mean the displayed width of each item in each row, you would need
to loop and keep track of the results of calls to Graphics.MeasureString().
 
You can try this.

You can replace MyStringCollection with its base (List<string>).
However, I coded it because that is what I do.
And you might have an object (<T>) which is not a string.
So the code below makes it updatable with a different entity. (aka,
substitute an Employee object for the string(s) below.


public class MyStringCollection : List<string>

{

}

class Program

{

static void Main(string[] args)

{

MyStringCollection sc = new MyStringCollection();

sc.Add("One");

sc.Add("Five");

sc.Add("Ten");

sc.Add("Twelve");

sc.Add("Thirteen");

sc.Add("Twenty");



//http://www.cubiczone.com/Articles/tabid/65/EntryID/23/Default.aspx

sc.Sort(delegate(string a, string b)

{

if(String.IsNullOrEmpty (a)) return 0;

if (String.IsNullOrEmpty(b)) return 0;

if (a.Length > b.Length) return 1;

if (b.Length < a.Length) return -1;

return 0;

});

//sc.Sort(new CustomStringComparer());

string longestString = string.Empty;

if (null != sc)

{

if (sc.Count > 0)

{

longestString = sc[0];

}

}

Console.WriteLine(longestString);



Console.WriteLine("\n\rPress ENTER To Continue");

Console.ReadLine();

}



}
 
thanks all for the help,
