Hi
I am trying to do a client side validation on a dropdownlist using the HTMLAttribute tag, but its not kicking in when I click submit button in my editform. Please see code below.
<SfDropDownList FloatLabelType="FloatLabelType.Auto" TValue="string" TItem="LookupModel" Placeholder="Select PoC Country" DataSource="@ddlLookup_PocCountries" HtmlAttributes="@(new Dictionary<string,object>(){{"required", "true" } })" @bind-Value="_model.ClientPoCCountry" >
<DropDownListFieldSettings Value="Value" Text="Text"></DropDownListFieldSettings>
</SfDropDownList>
Please advise?
