Refresh Datasource

[Miguel Varela Rodriguez]

Hi Syncfusion Team,

i have a dropdownlist and init like this:

selectUser = new ej.dropdowns.DropDownList({

popupHeight: "300px", 

dataSource: arrUsers, 

fields: {value: 'tPersonal1', text: 'tPersonal2'},

placeholder: "Operario",

allowFiltering: true

});

selectUser.appendTo("#selectUser");

At init time the arrUsers is a empty array, then i get from a ajax call the data.

How can i refresh the datasource?

Thank you in advance, and if you need more details just let me know.

Regards Miguel

Hi Miguel, 

Thanks for contacting Syncfusion support. 

Based on your scenario, you can assign the data to control in Ajax success by using DropDownList instance. 

Please refer the below code example: 

<code> 

onSuccess: function(args) {  

selectUser. dataSource = args.result;  

} 

</code> 

Refer the API Documentation link: https://ej2.syncfusion.com/documentation/drop-down-list/api-dropDownList.html?lang=typescript#datasource

now it looks like it got the data correctly, but i have a strange behavior.

List is filled with items, but is like empty no text etc.

see screenshot attached.

Hi Miguel, ,  

 

Based on your shared code and screenshot, we suspect that the issue is raised due to typo issue in field mapping. 

 

 Please refer the below code example: 

 

<code> 

 

selectUser = new ej.dropdowns.DropDownList({ 

                        popupHeight: "300px",  

                        dataSource: arrUsers,  

                        fields: {value: 'tpersonal1', text: 'tpersonal2'}, 

                        placeholder: "Operario", 

                        allowFiltering: true 

            }); 

 

 

</code>
