"SqlDataSource" with combobox to select
Good afternoon,
I am working with two combos and two "SqlDataSource".
These are the following problems:
1. When selecting a value for the first time in the "ComboBox1" the value that was assigned to "ComboBox2" gives it null and not know why.
2. I select another value again, and in the "Listeners" and not heard so I can not call the method "reload ()" the "store".
V Ext.Net 2.1
server-side
