Urgency deleted: It may be urgent to you, but it isn't to us. All that your stressing the urgency does is to make us think you have left it too late, and want us to do it for you. This annoys some people, and can slow a response.

You need to figure what language you are using first. The answer you get is going to be very different for C and C# since they are not even close to being the same.

Well first of all, I am not the one with the problem or attitude. Secondly, your question was not clear on how you expect to use the C programming language in a Winforms application. And thirdly, you have not demonstrated what you have tried to do yourself to solve your problem.

Just write a switch block, or a Collection class that will map the selected letter to its numeric value.

Fill the Text property of DDL as string that you want and in the Value property corresponding Integer value and get this integer value in your code and use this for furthere coding manner.

as your DDL id is as id="grade" then

int GradeValue=int.Parse(grade.Value);

Hi,

Use a Dictionary:
http://msdn.microsoft.com/en-us/library/xfhwa508.aspx[^]

C#

Dictionary<string, int> integers = new Dictionary<string, int>();
public Form1()
{
     InitializeComponent();
     integers.Add("S", 5);
     integers.Add("A", 4);
     // do this for all your values
}

And when you should get the int value from the selected option:

C#

int intValue = integers[(string)yourComboBox.SelectedItem];

Hope this helps.
