I have a grid that shows a list of Equipment. Each row has an ActionLink that sends the user to another View that shows a list of the children of that piece of Equipment. This is the code for that row:
columns.Bound(e => e.Id).ReadOnly().Title("")
.Format(Html.ActionLink("Open", "OpenChildren", "Equipment",
new{ id = "{0}" }, new { @class = "t-button" }).ToHtmlString()).Encoded(false).Width(120);So the route looks like this: http://localhost/Equipment/OpenChilder/GUID-GOES-HERE
The OpenChildren View is just another grid with the children of the parent and a partial view to show breadcrumbs. I removed the partial view and it still occurred.
When I don't have Databinding(databinding => dataBinding.Ajax()) set on the grid in OpenChildren, the OpenChildren event only fires once, but the grid doesn't bind. When i have databinding set to ajax, OpenChildren() fires twice.
What gives?

I couldn't understand what the problem is. What do you mean that the "OpenChldren" event does not fire? OpenChildren seems to be an action method not an event. Could you provide more code?

I'm sorry; i really don't know how to put it more clearly than that. OpenChildren IS an action method though, you are correct. I'm new to MVC and still call things by their old names. Like I was saying, when the grid is set to ajax databinding, it databinds normally, but the OpenChildren action method fires twice. If i remove ajax databinding, it only fires once. However, the grid does not bind.
OpenChildren firing twice is the core problem here. It's not that big of a deal right now, but when I get up to a few thousand kits of equipment, that's going to be a lot of info to return to the client twice.
I'm developing this on another network, so moving stuff around is problematic. Let me know what code you'd like to see and I will hand type it in.
There is no reason for a hyperlink (which is what Html.ActionLink renders as) to navigate twice except when there is some JavaScript involved. I will need a sample project to help you further. You can attach it to this thread.

Just found this bug again in my application. Searched for it, and guess what the first link to come up was? This one.
Figured it out, though. I had my GridAction (OpenChildren()) as both the Select method for the grid and the name of the View--so it would fire once to open the view, and then a second time to get the grid. Separated it out into a discrete View method and a GridAction method and it works fine now.
