Hi to all !!
I'm trying to make a select / combobox dynamic in a subgrid when click in add or edit button of navigation. The main grid contains student and the subgrid contains subject areas (physics, music, mathematical sciences, ....). A student can study one or more subjects, ¿ok?
I'm use the method 'onInitializeForm' in subgrid.
This is the code:
.... // in add options
onInitializeForm: function (formid) {
$.ajax({
type: "POST",
url:'dame_datos.php?nd='+new Date().getTime()+'&q=T&idc='+row_id,
// I pass the student id for sql get me only the subjects which not study.
// in the sql result, i get this data:
// {"rows":[["2","Music"],["3","Mathematical"]]}
// because this student was registered in physical, ¿ok?
datatype: "script",
success: function(grupos){
// #asignaturas is the combobox
$('#asignaturas',formid).append('<option value="' + ¿what? + '">' + ¿what? + '</option>');
}
});
}
My problem: I' can't / I don't know capture this values in the combobox.

Hello,
Do you want to populate the values only once or every time you open the form?

Hello,
If every time you want to populate the select when the form is open (i.e. if every time click on add or edit buttons) I think that beforeShowForm is the right event for you.
onInitializeForm is called only once when the form is created, but beforeShowForm every time we click on one of these buttons.
Define in colModel select with emty values
{ name: "myselect", edittype: "select", editoptions:{" : "}...}
then you can configure your server to return the html like this:
<option value="1">One</option>
....
The code:
beforeShowForm : function (formid) {
$.ajax({
....
success : function(response) {
$("#myselect",formid).empty().html(response.responseText);
}
...
});
}
If you want this to happen only once make this in onInitializeForm
Hope this helps
Regards
Tony
