Hi..
What is wrong? When the value changes I need to set values to other textboxes. What is wrong with my 'tags'?
When I set @bind-value , I get error that I can't have 2 change events.
I also need to bind to FoodType property.
thx again!
Telerik.Blazor.Components.TelerikDropDownList`2[CKonboard.Data.Models.EventFoodType,System.String] requires a value for the 'ValueExpression' ValueExpression is provided automatically when using 'bind-Value'.
at Telerik.Blazor.Components.Common.TelerikSelectBase`2.OnInitializedAsync()
at Microsoft.AspNetCore.Components.ComponentBase.RunInitAndSetParametersAsync()
at Telerik.Blazor.Components.Common.TelerikSelectBase`2.SetParametersAsync(ParameterView parameters)
<TelerikDropDownList Id="FoodType"
ValueChanged="@((string c) => EventSelected(c))"
Value="@Service.FoodType"
Data="@Lookups.EventFoodTypes()"
TextField="EvtType"
DefaultText="-Select First Event Food Type"
ValueField="EvtType"
PopupWidth="200px"
Width="200px"
PopupHeight="130PX"

Hi Jonathan,
You can read more about the error and its solutions in this article: https://docs.telerik.com/blazor-ui/knowledge-base/requires-valueexpression
When using the <Parameter>Changed event, you can use @bind-<Parameter>, that's how the framework operates.
