Error double click form caption with StrataListView

Edhy Rijo — Tue, 09 Nov 2010 18:11:29 GMT

On some situation, when a form with StrataListView is double clicked on the form's caption to maximize it, an exception will be trigger by the StartaListViewItemCollection.Sort() method.

Any ideas on how this could be trapped? also, any news on upcoming updates for the StrataListView?

Here is the exception:

InvalidOperationException
Failed to compare two elements in the array.

My guess is that when you double click the form, thus maximizing it, this in turn ends up re-rendering the listview, which needs to do a sort. Then something is breaking. Not sure I can of much more help without a sample app though.

Hi Greg,

Based on the stack it is coming from " MicroFour.StrataFrame.UI.Collections.StrataListViewItemCollection.Sort()" method.

I have a checkbox in the first column of my listview and in my subclass I handle the OnDoubleClick to automatically check/uncheck this checkbox, also when clicking the 1st column header, I have code to check/uncheck all items, but as I reported before, this may be fighting with the sorting which cannot be disabled yet.

I catch this on a form when double clicking the form's caption to maximize it. I need to put more time (which I don't have :crazy:) to try to duplicate this more clearly.
