How to create a custom row sorting function for a gridpanel ?
I have implemented a Web - Application which features a GridPanel which can be grouped or ungrouped and where the rows should be sorted alphanumerically (like the standard grid sorting function does) but with the exception that some rows which represent summary rows should not be sorted at all and should stay at the same row position.
To archieve this i wanted to write a custom row sorting function for the gridpanel. Can someone give me a hint how to archive this ? (overwrite which functions, how to implement). Or does anybody know literature, tutorials, examples etc. or could share source code on how this can be done ?
