Not clear - are you asking what the code behind should be for a fileuploadcontrol in a datagrid, or are you asking how to call a vb.net function from C# code-behind?

Hi CHill60,
Thanks for your time. Actually what I want is to fill the dropdownlist on file selection of fileupload control. which are in DataGrid in asp.net. I have tried everything but cannot find event on which i can call fill dropdownlist function.
Any of c# or vb.net code/ Idea will do.

There are server side functions so maybe you can work with that.
