ASP.NET Datagrid Question 1

[byrne1]

In my datagrid I have a dropdownlist that appears when the user is editing an item. I populate this ddl with values from a table. When a user clicks on a value in this ddl, I need to use the value in a lookup for another table and return fields to populate another ddl on the grid.

An example would be like having one ddl populated with the names of states. When a user picks a state, I would execute a SQL statement like "select city where state='TX'" and use this dataset to populate a ddl right next to the one for the state.

Is this possible?

Yes, it is possible. Read this article

there is a live sample on the same page, using State/Zip master/detail multiple ddl example. Hope this helps.
