Hi, I'm trying to use the RowExpanded server-side event to populate a pulldown list which appears within the 'Add New' row of the Bands section (the pulldown list needs to be populated before the user tries to make a selection). However, for some reason, the RowExpanded event isn't firing the code when I actually expand a row. Am I missing something obvious?
Can anyone help with this? It's vital that I'm able to populate a pulldown list when a row is expanded. My company is evaluating this software and a competitor's software - if this issue can't be resolved, then we may end up going with the competitor.
Hi MartinWright6,
I took a look at this. I attached RowIslandPopulating and RowExpanded server events. I got the first event with ajax set to true and false. I got the expanded event on the first (loading) postback when ajax was FALSE. However, when it is true, the RowExpanded event fires on the second postback. This is because the row has not actually expanded until it comes back from the ajax postback and expands on the client. So you have two choices. You could turn off enable ajax or you could try to handle row island populated to set up the pull down items. Let us know if you need any help.

Hiya David,
Firstly, thanks for taking a look. Unfortunately, setting "EnableAjax" to false didn't seem to work - the code is still not firing. I've added my .aspx code below... could you take a look and let me know if you can spot the issue please?...

Hi,
Your problem is that you have InitialDataBindDepth set to -1. This means everything is loaded on the client initially; there is no load on demand. The Row Expanded event on the server will not fire until the next postback. What you could do is handle the client side row expanded event and then find the drop down provider and call loadItems(params) on it. Or initiate some sort of postback.
