[Solved] Databinding actions using lambda exp

[Joan Vilariño]

Hello...

I have my ajax grid bound like this:

.DataKeys(dk => dk.Add(o=>o.Id))
.DataBinding(db => db.Ajax().Select("_select","myController").Update("_update","myController").blah blah blah

myControllerController has this:

[GridAction]
public ActionResult _select()
{
     return whateever...
}

[GridAction]
public ActionResult _update(long id)
{
    return whatever....
}

As you see _update takes the parameter of the entity's key...

I want to change Grid databinding actions to use lambdas... in the _select case is easy:

.Select<myControllerController>(o=>o._select())

but in the _update case, I don't know how to pass the id parameter:

.Update<myControllerController>(o=>o._update(??????))

Can you give me a way to do this? I find the code is much clearer using lambdas, and it allows refactoring within the IDE.

Hi Joan Vilariño,

You should pass any integer to satisfy the compiler:

.Update<myControllerController>(o=>o._update(1))

Thanks, that did it...

anyway, I've rolled back to the previous mode, because when I use lambdas and hen for example, edit, update, edit, update a pair of times, IE8 shows a bubble telling me that the document has caused the navigator to switch to compatibility mode, and it reloads the page.

I've confirmed this doesn't happen if you use the old Update("action","controller") way, but does it when you use .Update<MyController>(o=>o.myAction);

Any hint on this? Its kinda extrange.

Cheers
