Hello,
I'm using the TreeList.Sort method to manually sort only certain nodes of a TreeList based on certain actions the end-user does. This system works perfectly when trying to sort a single column, but what if I need to sort by two or more columns? Like when you sort the TreeList by pressing Shift and clicking different column headers, I would like to sort my tree based on the values of two or more different columns programmatically. Is there a way to achieve this?
Thank you,
Daniele
Hello Daniele,
If you need to sort all nodes in your TreeList, I recommend that you specify the column's SortOrder and SortIndex properties. The SortIndex property determines the order of columns that will be used to sort the nodes. For more information, please refer to the following help topic: Sorting via Code.
Otherwise, if you need to sort only particular nodes, then you need to create a custom IComparer class that takes into account the values from multiple columns and pass an instance of it to the TreeList.Sort method. You can refer to the following StackOverflow thread for an example: IComparer on multiple values.
Should you have additional questions, let me know.
Hi Christian,
since I need to sort only particular nodes, I'll try using a custom IComparer.
Thank you for your help.
