DropDownDataGrid Validation Configuration Trouble

Radzen Studio Blazor Server
1

Hello,

It seems the DropDownDataGrid does not support validation but this previous post makes it clear it does support validation so I'm probably doing something wrong again.

From reading that post it seems the type of the DropDownDataGrid ValueProperty impacts which validator is used. In my case the ValueProperty is a string so I implemented two validators but neither seem to be firing so clearly I am not understanding correctly how to use validators with the DropDownDataGrid.

Razor with excess removed for brevity:

<RadzenTemplateForm>
  <RadzenNotification />
    <RadzenSteps>
      <Steps>
        <RadzenStepsItem>
          <RadzenFieldset>
            <HeaderTemplate>
            </HeaderTemplate>
            <ChildContent>
              <RadzenAutocomplete />
              <RadzenRequiredValidator  />
              <RadzenAutocomplete  />
              <RadzenRequiredValidator />
              
              <BusinessNameLocationComponent Name="SelectBiz" />
              <RadzenRequiredValidator Component="SelectBiz"  />
              <RadzenLengthValidator Component="SelectBiz" Min="100"  />
            </ChildContent>
          </RadzenFieldset>
        </RadzenStepsItem>
      </Steps>
    </RadzenSteps>
</RadzenTemplateForm>

Hi @patrickh,

Validation of all input components will work only if Data property of RadzenTemplateForm is set and the Value property of the input component is two-way bound (@bind-Value expression). Check this demo for reference:
