TelerikGrid Creating Command Buttons in DetailTemplate Grid

[Steven]

I am in the learning phase of Telerik currently, so I assume that I am missing something obvious here.  I have the following code:

<TelerikGrid Data="@EquipmentList" Groupable="true" Pageable="true">
    <DetailTemplate>                   
        <TelerikGrid Data="@context.TaskList">
            <GridColumns>
                <GridColumn Field="TaskTitle" Title="Task"></GridColumn>
                <GridColumn Field="TaskDetail" Title="Detail"></GridColumn>
                <GridCommandColumn>                    
                    <GridCommandButton Command="OpenPDFCommand" Icon="file" OnClick="@(()=> FileService.OpenPDF(TaskPDF))"> Test Command</GridCommandButton>             
                </GridCommandColumn>
            </GridColumns>
        </TelerikGrid>
    </DetailTemplate>
    <GridColumns>
        <GridColumn Field=EquipmentName></GridColumn>
    </GridColumns>
</TelerikGrid>

 

This is the beginning of a maintenance task tracking site.  The basic format of data is

List<Equipment>   and Equipment has List<MaintenanceTask> in it -- so a List within a List. 

 

I can get the data to show properly, but when I add the Command column to start adding functionality to the page, I get two errors that I don't fully understand:

1) 
The child content element 'ChildContent' of component 'GridCommandColumn' uses the same parameter name ('context') as enclosing child content element 'DetailTemplate' of component 'TelerikGrid'. Specify the parameter name like: '<ChildContent Context="another_name"> to resolve the ambiguity C:\Users\StevenDeam.ASIMOV\source\repos\JM3Telerik\JMWeb\Pages\Maintenance\MaintenanceMain.razor 

2) 
The name 'context' does not exist in the current context	JMWeb	C:\Users\StevenDeam.ASIMOV\source\repos\JM3Telerik\JMWeb\Pages\Maintenance\MaintenanceMain.razor	9	

 

I did test adding a bogus context:

 

<GridCommandColumn>                    
                    <ChildContent Context="test">

 

This changed the error to say the namespace "test" could not be found.  I am missing something on how the commandcolumn relates to the grid it seems.   And none of the documentation that I can find shows the context of a commandcolumn needing to be changed.

This changed the error, and said that the namespace "test" could not be found.

I found the appropriate help page, https://docs.telerik.com/blazor-ui/knowledge-base/nest-render-fragment this seems to answer my question.
