I have a dropdown within a for loop that looks like this:
<kendo-dropdownlist
[name]="'Type_Name_' + index"
[data]="this.types"
[textField]="'name'"
[valueField]="'id'"
[ngModel]="{
id: UserInfo.TypeId,
name: this.types[UserInfo.TypeId].name
}"
(selectionChange)="onTypeChange($event, UserInfo)"
>
<ng-template kendoComboBoxItemTemplate let-dataItem>
<span [title]="dataItem.name">{{ dataItem.name }}</span>
</ng-template>
</kendo-dropdownlist>types: any = [];The types are pulled from the DB and look like this:
[
{
"id": -1,
"name": "Select"
},
{
"id": 1,
"name": "A type"
},
{
"id": 2,
"name": "Another Type"
}
]
The dropdown loads ok. But when I choose the value "Select" which is -1 the whole dropdown disappears.
Similarly because this is in a for loop I allow more dropdowns to be dynamically added.
When I dynamically add them with a value of -1 they don't appear. When I add them with a value of 0 they do appear.
I'm constricted to use -1 as the start value.
