I can add the button, but I need to be able to identify the row that the button was on in the @onclick event so that I can pop-up a form with information specific to that row.

Hello Dan,

A custom command button gives you the item in its event arguments: https://docs.telerik.com/blazor-ui/components/grid/columns/command. While this requires a dedicated command column, you may already have it for the CRUD operations.

If you want to use a Template in a data column, you need to use a lambda expression in the OnClick handler so you can pass extra data from the context, something like this:

<TelerikGrid Data="@MyData" Height="400px"
             Pageable="true" Sortable="true" Groupable="true"
             FilterMode="Telerik.Blazor.GridFilterMode.FilterRow"
             Resizable="true" Reorderable="true">
    <GridColumns>
        <GridColumn Field="@(nameof(SampleData.Id))" Width="120px">
            <Template>
                @{ 
                    SampleData currItem = context as SampleData;
                    <TelerikButton OnClick="@( _ => HandleClick(currItem.Id) )">click me</TelerikButton>
                    <button @onclick="@( _ => HandleClick(currItem.Id) )">I do the same</button>
                }
            </Template>
        </GridColumn>
        <GridColumn Field="@(nameof(SampleData.Name))" Title="Employee Name" Groupable="false" />
    </GridColumns>
</TelerikGrid>

@code {

    void HandleClick(int theId)
    {
        Console.WriteLine(theId);
    }

    public IEnumerable<SampleData> MyData = Enumerable.Range(1, 30).Select(x => new SampleData
    {
        Id = x,
        Name = "name " + x
    });

    public class SampleData
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }
}
