How to click on columnheader, and sorting in datagrid ?

Question

Hi. Nice site :)

As the topic says. When i click on a colum header, i want to sort the data in the datagrid..

The datagrid is using an arraylist as source..

So question 1:
How do I "catch" the click on certain column header

question 2:
How do I sort the data when clicking on the column header.

Thank you,

Hi Lasse,

    Do you have many columns in your ArrayList? You can write code on the DataGrid''s MouseDown event to catch the click on Colum header.

    And for sorting the data,save your data in arrary list and bind your dataview and set the Sort property of DataView .After that call DataGrid''s Refresh method. 

    If you are populating from a database,you can use the SQL statement Select...from...OrderBy ,but you need to load data from database every time you want to sort the data, which makes application slower.
