Yes thanks.
Actually I'm creating some "help" method to achieve this task.
But in the documentation says if the dataprovider of the combobox has
a data property the selectedIndex will search on it for the matching
value.
I notice that with the following data.
/**/
dataProvider for the combobox from Database-table:
This SQL produce this output.
"Select id as data, cat_name as label from users_categories";
//with this SQL I don't need to specify labelField = "cat_name" in the
combo;
//After asign to my_combobox.dataProvider = cat_result;
The dataprovider becomes in..:
index | data | label
-----------------------
0 | 1 | "cat one"
1 | 2 | "cat two"
2 | 3 | "cat three"
3 | 45 | "cat 45"
4 | 95 | "cat new"
When I put my_combo.selectedIndex = 1;
the combo select the dataprovider[1] item, "cat two".
Whe I put my_combo.selectedIndex = 45; //they search in data prop.
They display correctly the dataprovider[3] item "cat 45".
This is a bug?
Thanks
