Hello,
today I downloaded a trial version and I'm testing the grid functionalities.
It Looks great and offers a lot of excellent Features. Smaller grids with "local data" worked really fine.
But I got stuck when playing around with the remote header filtering example.
I adapted the code snippets from the demo and tried to load the data from an mysql database.
What I receive is a perfect grid, but wothout any content! It says "No rows to Display".
What I have done:
I created a table called "ordercustomers" in the db "paramquery".
It includes the columns: ShipCountry, ContactName, OrderID, OrderDate, ShipRegion, paid, ShipVia, RequiredDate, ShippedDate, Freight, ShipName, ShipAddress, ShipCity, ShipPostalCode.
I created a php file to fetch the data "getdata.php" I added the DB_HOSTNAME, DB_NAME, DB_USERNAME and DB_PASSWORD.
I changed the URL code in the example.
Hopefully someone can give me a hint and help me out.
Greetings,
Andre
