How to let the user define search filters?

[Terry Olsen]

I have an ASP.NET web page that can display about 25 columns of data from an
SQL database. I have it right now using a CheckedListBox to allow the user
select the columns for display in the DataGrid. I have hardcoded 3 columns
for filters and allow the users to type in to a TextBox the filter data.

Are there any Query Builder GUI examples that I might use to allow the user
to build their own query using any and all the columns?

You can try to use our Active Query Builder. It has powerful and
easy-to-use visual query building interface.
