tms fnc datagrid component shows in fixed rows

tms fnc datagrid component shows in fixed rows as you can see in the attach, what can i do?

Thanks Adrian

Check boxes

and how can i format summary currency value for the total row?

How exactly did you add the checkboxes? For the formatting, You can add a callback to the calculation definition and then set the calculation format

  TMSFNCDataGrid1.ColumnCalculations[9, 'Average Fare Price'] := [CreateGroupColumnCalculation(gcmAverage,
  procedure(AColumn: Integer; ALevel: Integer; var AOptions: TTMSFNCDataGridDataColumnCalculationOptions)
  begin
    if ALevel = 1 then
      AOptions.CalculationFormat := 'Sub-Average Fare Price: $%.2f'
    else
      AOptions.CalculationFormat := 'Average Fare Price: $%.2f';
  end
  )];

Hello,

i have added the checkboxes via the object inspector for the columns of the datagrid as shown in the attach.

Before, i have added the checkboxes in code with a loop throug all the records, but the same result.

I have used the formatting you proposed but the result is:

Can you provide a small sample demonstrating both issues?
