Hello Sam,

Sorry for my late response !

Thanks for first response I take this and give you as soon as possible.

Thanks,

Alex.

Alex,

I would like to ask you to clarify it for me -- Assuming you retrived a record that is a GroupBy record (not sure what the role of checkbox is), and it has child records - What is being checked or changed?  Correct me if I am off track, and tell me what you are trying to achieve. 

Thank you,

Sam

Sam,

Some explications :

I have for example an ObservableCollection where Items has a bool property.

I Bind this property on checkbox recordheader => It's ok,

But when I click on the CheckBox in Header, I want to check / uncheck all checkbox in recordheader with the respect's grouping.

Thanks,

Alex.

Thanks Sam,

But It's doesn't give me the response of my question (and this exemple doesn't take groupby record when click on header prefix area Checkbox),

How could't I get the structure of any groupby with each children record and his Header witch contain  my checkBox (or another control) ?

Thanks  !

Hi Sam,

Has indicated in this forum that's doesn't work with grouping (is grouping check/uncheck in header check / unchek ALL record and not only childs record in the groups we'r click !)

I don't see how can do this fonctionnality, that why I witch to know how detect childs record of an header in groupby !

Thanks,

Alex.

Hello Alex,

With the sample that was included in the forum post I provided you could group the records, and click on the checkBox located on the header record which had the functionality to check/uncheck its child records.

If it doesn't work for you, please submit a small sample that you have implemented with checkboxes  and I review it and make suggestions.

Thank you,

Sam
