Output values does not match selected values

Hello community,

I use my own Grid DialogTemplate box that contains the MultiSelect component to insert a new record.

I have a problem with processing the MultiSelect value, when selecting any number of items, only the first one will appear in the output.

Please ask for help or direction in the right direction.

Well thank you

Hi Patrik, 

Greetings from Syncfusion. 

We have analyzed the provided information and we suggest to use the below model class to retrieve the records from the client-side, From the below code example, we have returned the multiselect dropdown values as an array to the controller. So the type has been mismatched and you will get this defect.  

We have created a sample with the above mentioned model class and that can be download from the below link,
