Hi I have a drop down list place above a gridview. I have a column named course I want the gridview to display the data based on the selection of the drop down list.

Joginder Banger I have errors after trying getting the info from online but i deleted the codes as they do not work. The dropdown list data comes from a table in databse. So on selection of a course name the gridview should display all records that contain the course name same as the selected value in the drop down list. I am not using the data table I just connected the gridview to sql data source.

Hi how it is possible no error show your question. Plesae check table and select query because if any error mention you have then i find out what is missing. so no idea without seen project and related pages.
