There is some confusion over how data is sorted in the two demos your have provided below
1) grouping demo
http://localhost:7777/grid/grouping
2) custom Ajax binding demo
http://localhost:7777/grid/custombinding
In case 1, the groupable sorting seems to take precedence whereas in 2, the column sorting takes precedence.
Try the following in both cases..
Sort the contact name column in descending order and then try to group by this column.
In case 1, data is again sorted in ascending order of contact name whereas in 2, it remains in descending order.
After that, in case 1 sorting by clicking on the group button takes precedence(i.e clicking on the same column name to sort it is ignored and only)
whereas in 2, it is the reverse(i.e. clicking on column sorts the data so it takes precedence whereas sorting by clicking on grouping button is ignored). Is this merely due to how you have implemented the custom ajax binding or is it some bug in the grid ?
