Displaying Combox in Radzen Grid Column

I have the following requirement where the user can select an item in the combo box within the grid.


But i cannot find any relavent documentation for adding a combobox to RadzenGrid. Please advice

Similar example can be found here:

The DropDown is defined in column EditTemplate and the same approach can be used for Template.

Thanks.But i'm having issues displaying the grid within a dialog form.The table wont get displayed

<RadzenTemplateForm Data="@portfolioWrapper" TItem="PortfolioWrapper">
<div class="row">
                <RadzenDataGrid  AllowFiltering="true" AllowPaging="true" PageSize="5" AllowSorting="true" EditMode="DataGridEditMode.Single"
                                Data="@assetTypes" TItem="string" >

The object assetTypes is a list of string
protected List<string> assetTypes = new List<string>();

You might need to check carefully our demos. Example of DataGrid inside dialog can be found here:
