asp.net datagrid control:
Hi everybody
I have a GridView control where my datasource is an ArrayList, I would =
like to be able to sort the grid, therefore I set the AllowSorting to =
true, so far so good. The ArrayList consist of a collection of =
Customer-objects, where the "Title" (a string) is the name of the =
Customer.
Below is my sourcecode for the Sorting event and the control itself, I =
don't know what is wrong, but when I click a column to sort I get an: =
System.StackOverflowException was unhandled
Can anyone please show an example of a sorting that works with an =
ArrayList as datasource in a grid.
If you need any addiotnal details let me know. :o)
Thanks in advance
