I solve the problem! The DropDownList was inside a table. This is the previous code:
<tr> <td id="selectProject"></td> </tr>
This is the correct code:
<tr> <td><div id="selectProject"></div></td> </tr>
Thanks!
I use the selectrow method in the ready callback like you suggest and it works fine!! Thanks
Thank you! I set async to false and this solves the problem! Thanks jQWidgets team
