Hey,
Working on dynamically creating and filling RadGrids in the code rather than in the front-end for an ASP project using a VB backend. Got some really useful advice so far, but today I was trying to get a CommandItemTemplate working on a detail table, and I've encountered a rather large problem... whenever I click to expand the grid the whole grid just doesn't render. All I get is a thin line instead of the grid. It renders fine when I first load it, it renders fine when I try to add a new record, but on ExpandCollapse it just seemingly disappears.
I'm assuming that something is preventing the data from binding, or the radgrid from rendering, but I have no idea what it is. I had the same problem earlier on InitInsert and the way I got around it was to simply run the code to render the grid again from the beginning, and then it appeared with the ability to insert a new record. If I do the same thing with this however it appears again in it's non-expanded state.
Any help would be appreciated.

Hello Pete,
This is a data binding issue. Make sure that you are binding the RadGrid with advanced data binding using its NeedDataSource event. Check the following demo which explains the same.

Fantastic! Thanks Shinu, that demo was exactly what I needed. Even though it doesn't seem to work now it did on Friday when I updated my code and now the grid doesn't keep disappearing when I click buttons, which is fantastic. Now I just have one more query remaining, which I figured I'd post as a separate topic.
Thanks again,
Thanks again,
