LLBLGen Pro 2.0, adapter scenario

There are times when I would like to delay loading a grid or list control that is attached to an LLBLGen datasource. For example, a datasource that loads a grid as a result of a search. What is the best way to accomplish this?

I set the visibilty on the grid to false and then set it to true when the search is done.

It's indeed a bit problematic, as due to the declarative programming, asp.net just binds the grid to the datasource at page init time (or whatever stage) and this makes the grid simply call the datasource's ExecuteSelect(), which has to produce data.

As it's unknown if the data has to be produced or not, the datasource control simply loads the data and returns it.

To overcome this, you indeed need to hide the grid until you have something to show. Another way is to set a filter which will fail, although this is a bit of a hack.

Make the grid invisible! I was looking for something much harder.

This answer suits me perfectly and it is quite easy to do. I can't believe I didn't think of it.
