Question: I have a Foreach which contains a RadzenNumeric and Validation for it. The issue I am having is that the Name and Component are the same for every item in the Foreach. So if 1 out of 10 have a value then they all do not show the validation error.

Question is, what is the best approach to make the name Unique? Is there a way to do a Counter within the Foreach and just add that value to the end of the Name and Componenet?

```
@foreach (Models.Ingredients.MeasuredIngredient measuredIngredient in CompoundIngredient.MeasuredIngredients)
{
    <div class="ingredient-seperator"></div>
    <div class="row ingredient">
        <div class="amountInput col-6 col-md-2">
            <RadzenNumeric class="newInput" Name="Amount" @bind-Value="measuredIngredient.Amount" TValue="decimal" Min="0"></RadzenNumeric>
            <RadzenRequiredValidator class="rz-message rz-messages-error rz-message-popup newInputValidation" Component="Amount" Text="Amount is required" DefaultValue="0" Popup="true" />
        </div>

    </div>
}

```

Answer: 
It should be possible to number them.

```
@{ var index = 0; }

@foreach (Models.Ingredients.MeasuredIngredient measuredIngredient in CompoundIngredient.MeasuredIngredients)
{
    index += 1;
    <RadzenNumeric class="newInput" Name="@("Amount"+index)" @bind-Value="measuredIngredient.Amount" TValue="decimal" Min="0"></RadzenNumeric>
    <RadzenRequiredValidator class="rz-message ..." Component="@("Amount"+index)" Text="Amount is required" ... />
}

```
The issue with Radzen Name and Component is that it does not support Complex Types. Based on Henk Holtermans suggestion here would be how to get it working

```
@{
   int i = 0;
   string amount = "Amount" + i.ToString();
   string type = "Type" + i.ToString();
   string ingredient = "Ingredient" + i.ToString();
}
@foreach (Models.Ingredients.MeasuredIngredient measuredIngredient in CompoundIngredient.MeasuredIngredients)
{
    <div class="ingredient-seperator"></div>
    <div class="row ingredient">
         <div class="amountInput col-6 col-md-2">
               <RadzenNumeric class="newInput" Name="@(amount)" @bind-Value="measuredIngredient.Amount" TValue="decimal" Min="0"></RadzenNumeric>
               <RadzenRequiredValidator class="rz-message rz-messages-error rz-message-popup newInputValidation" Component="@(amount)" Text="Amount is required" DefaultValue="0" Popup="true" />
         </div>
    </div>

   i++;
   amount = "Amount" + i.ToString();
   type = "Type" + i.ToString();
   ingredient = "Ingredient" + i.ToString();
}

```
