How to display a editable checkbox field in grouping grid ?

[bmagana]

Hi,

I have a grouping grid with some fields, incluiding a checkbox.

The problem is that if I want to make the checbox editable, I must put in <ext:GroupingSummaryColumn>, I can´t specify that is a CheckboxField, so, the column displays "true" or "false"... when I click the column, it display de checkbox ok only while editing this item.

If I put just like <edt:CheckboxField> it displays ok, but I can´t edit it.

The code for this column is :

                    <ext:GroupingSummaryColumn 
                        ColumnID="Realizada"
                        Header="Status" 
                        DataIndex="Realizada"
                        Sortable="true" 
                        Groupable="true"
                        Width="25">
                        <Editor>
                             <ext:Checkbox ID="checkbox" runat="server" />       
                        </Editor>  
                    </ext:GroupingSummaryColumn>
