I have RadzenDropDown whose data comes from other components or DB and need to load pre-selected items, I could not find a way to do that. For example below, "allExpressions" comes from other control where few items are already pre-selected.

List allExp = "a","b","c","d" but "b" and "c" should be checked when loaded in.

\<RadzenDropDown  
AllowFiltering="true"  
FilterOperator="StringFilterOperator.Contains"  
FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive"  
Multiple="true"  
Data="@allExpressions"  
TValue="IEnumerable"  
@bind-Value="expressionNameList"  
TextProperty="Name"  
ValueProperty="Name"  
Change="@(args =\> OnChangeExpression(args))" /\>

Hi @ShishirDahal,

You can refer to the [DropDown demo](https://blazor.radzen.com/dropdown). The one which has multiple selection enabled shows how to select multiple values.

```auto
 <RadzenDropDown @bind-Value="multipleValues" 
     Multiple="true" 
     Data="@customers" 
     TextProperty="CompanyName" 
     ValueProperty="CustomerID"
/>
@code {
   IEnumerable<string> multipleValues = new string[] { "ALFKI", "ANATR" };
}

```

What if you were to have a List of variables that you want to load into the drop down? For example a List of integers.

The last DropDown from the example has the same configuration:

```auto
 <RadzenDropDown AllowClear="true" AllowFiltering="true" Multiple="true" FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive" Data=@products 
@bind-Value=@multipleValuesdisabled TextProperty="ProductName" 
ValueProperty="ProductID" DisabledProperty="Discontinued" Change=@(args => OnChangeDisabled(args, "DropDown with multiple selection")) Class="w-100" />

@code {    
   IEnumerable<int> multipleValuesdisabled = new int[] { 1,2 };
}

```
