Hi Matt,

 Thanks for the quick reply.

 Unfortunately your sample solution will not work for our requirements. I am actually trying to create a grid where the sums are just like any other row and we would be able to have multiple layers deep, (sums within sums within sums). I’ve tried to take a screen shot of what we’re trying to achieve (see attached image).

 As you can see we have the totals for 2 Continents, if you expand a Continent you will see the totals for each Country in that Continent, if you expand a Country you will see the data for each City in that Country. Note that the data for the parent rows (Country) is just a total of it’s children’s rows (Cities).

 From what I’ve seen, I don’t think this can be done using summary xamDataGrid row summaries. I’m guessing it’ll be how we store our hierarchy and the relationships within our data. If this is true how would we properly do this? CollectionViews of CollectionViews which hold lists…?

 Thanks

Hi Matt,

 Your solution was exactly what I was trying to do.

 Thank you for your help!

Is there any way to change the + symbol to >??

Hi,

Is it possible to dynamically generate my grid’s Fields during runtime instead of how we’re doing it in the sample solution you provided.

The reason I am trying to do this is because the rows will have a different number of children. Some may only have the parent and 1 child whereas others may have the parent with possibly 5+ children and each one of those may have its own children.

I think I can do this if the parents and children were bound to the same object but in my case the parent is bound to the sum of all it’s children and the lowest level child is bound to its own value.

Thank so much for your help.

HI,

 I modified the sample to add the columns dynamically at run time.

 The XamDataGrid will automatically create fields for any public properties in the class that it is bound to.

 So I only need to add two unbound fields.

Please review my sample.

 Sincerely,
