Hi I am a student do anybody know after populating the combobox with the database values. How to display the same value in the text box. When I select a name in the combobox the same name should be displayed in the text box I am using seleted item. Here is the code.

I am getting the error the following error using the foreach loop

foreach statement cannot operate on variables of type 'object' because 'object' does not contain a public definition for 'GetEnumerator'
