Hi there,

I would like to use the MultiSelect to set the value of a cell in a TreeList.

My code almost works, but once the MultiSelect closes the values displayed in the grid are not what I expected.

I tried using a template to display selected values, but it doesn't look right.

Here is a dojo link https://dojo.telerik.com/OdAFErap/11 and below the code of that dojo

 

Thanks in advance,

Hello, Reinaldo,

Thank you for providing an example that demonstrates the problem.

Here is the modified version and the changes I made:

1. Improve the if statement in the template:

<script type="text/kendo" id="alertsTemplate">
               # if (Alerts !== null && Alerts.length) { #
              <ul>
                # for(var i = 0; i< Alerts.length; i++){ #
                <li>#: Alerts[i].name #</li>
                # } #
              </ul>
              # } #
 </script>

2. The Alerts field in the model should not be of type string:

schema: {
                            model: {
                                id: "id",
                                expanded: true,
                              	fields: {
                                  	Name:   { type: "string", editable: false },
                                  	//Alerts: { type: "string", editable: true }
                                }
                            }
                        }

Let me know if you have any further questions.
