The Core Data Documentation states that: The fetch request associated with the [fetched] property can have a sort ordering, and thus the fetched property may be ordered. How do I specify the sort descriptors for the fetched property in Xcode's data model editor? I can't find a relevant field anywhere. I'm developing for the iPhon...
I have a column with 4 fields named : a> Main, b> Forward c> Back d> Link, if I use pre-defined sorting of datagrid with the column names which will be alphabetically, then the order is c>Back b>Forward d> Link a> Main. But, I do not want to sort based on the alphabets. I prefer to sort by names of the column fields. i.e. somehow give pr...
I've recently written a piece of code to read some data from a file, store it in a tuple and sort all the collected data by the first element of the tuple. After some tests I've noticed that using Seq.sortBy (and Array.sortBy) is extremely slower than using IEnumerable.OrderBy. Below are two snippets of code which should show the behavio...
Hi everyone! I have a problem with sorting a DataTable. I'm using DataView.Sort and then DataView.ToTable() to get the sorted table. Then I go through the table row by row and create nodes in a TreeView which is shown in a desktop application. My problem is that I can sort the data in ascending order and it is shown in the TreeView in...

In my project there's a need for a multi-column list control. I wish the list could be automatically sorted upon clicking on the column header. Since i'm using Boa constructor, the solution should not be too obtrusive, i.e. compatible with Boa's ability to read and regenerate the code. So I thought, there can be either a built-in cont...

I want to sort the records by the value of b in subList. records at 0 has a list of "...
I have an array of CLLocation objects and I'd like to be able to compare them to get distance from a starting CLLocation object. The math is straight forward but I'm curious if there is a convenience sort descriptor to go about doing this? Should I avoid NSSortDescriptor and write a custom compare method + bubble sort? I'm usually compar...

Hi, I have a datagrid. I add a row to the datagrid using an ADD button. Once I add, I sort the datagrid based on a column. I also provide the serial numbers i.e. row numbers as first column to the datagrid. But, the serial number function does not apply after sorting. Hence, a new row added for e.g. row 5, based on sorting should be row...
