Sorting of templated columns

[Jerry Kurata]

Hi,
I have a grid with columns that display multiple fields in a cell.  The layout of the cell is defined via a template.  I have a few questions about the sorting.

1. What is the best way to implement sorting of these columns?  For example a cell in the column could display the a value that is an average and the number of items that went in to determining the average.  When the user sorts the column I want to sort only on the average. 
2. I also need to do multi-column sorting.
3. Is there a way to ensure that any null columns end up at the end of the sort order after all of the rows with a value.

Thanks,

Jerry

Hi Jerry Kurata,

You may  find the SortMemberPath property of the DataColumn useful in your case.

For more complex scenario you may implement a custom sorting like :
1. Handle the Sorting event of RadGridView ,
2. Within the event handler sort the item with your own logic

more info on custom sorting you may find in the this online article.
