This is not a Radzen datagrid specific problem but one may have a solution that I could not see.
I have two tables, one is the parent of the other. I need to show the parent table in a datagrid with the addition of a field that is summed from a field from the child table.
Is there any suggestion for this problem?
Here is an example using this demo:
<RadzenDataGridColumn Title="Total Quantity">
<Template>
@(context.OrderDetails.Sum(od => od.Quantity))
</Template>
</RadzenDataGridColumn>
