newby hashtable question

Hi all
Darius here, and as you will see from this question, Im new to the world of programming.

Im trying to write a program that i plan on using for the registration of students. It is Winform based, and consists of 9 textboxes that I use to gather data from the user. Now I have created a student class, and a hashtable to tempereraly store the gathered data in.
Now my Question is, how do I go about extracting the data from the hashtable, and displaying it in either a new window, or back in the original textboxes from where it came in the first place. So in other words, if I type in the student number(key) in the textBox.1, I want the values(the data from the other 8 textboxes) to reappear in those textboxes as they were entered.
I know there is no myTable.Show method, but im sure there has to be a way to do it. Can anyone tell me how?

Thank you all, for any and all help.
Darius

How have you created the hash table? Is it a file that contains the data, or an array of structures within the program?

public static bool TChekStudentIdExists(string strstudentID)
{
IDictionaryEnumerator en = objstudent.GetEnumerator();

while (en.MoveNext())
{
string str = en.Key.ToString();
if (str == strstudentID)
return true;

}
if (objstudent.Count == 0)
return true;
else
return false;
}
