Hi everyone,

In 4.7.1. I am trying to use VNext capabilities to load a GridView.
ItemType is set, SelectMethod is set.
In code behind the public IQueryable<itemtype> GetData() is set.
It loads data from a stored procedure. The datatable rows are converted to a List<model> object. That data is called in het GetData() method and casted to IQueryable

When I load the page I see the method is called.

It will not give data because I need to add the value of a DropDownList.SelectedValue.

When selecting an item from the DropDownlist the GetData() method is not called again.

What do I have to do to get that working?

What I have tried:

See 'describe the problem'section.

For DropDownList loading in the same way I do not have this problem

Ummm, what is this VNext you speak of?

Sigh. "vNext" refers to the "next version" of a product, not a product itself. So, you're not using "VNext capabilities".

read this than: vnext in It is about a way to load the data

You seem to have a comprehension problem. From the article you linked:
The vNext releases of .NET and Visual Studio include a ton of great new features and capabilities.
Whever you see "vNext", it is ONLY ever referring to the next version of a product, be it ASP.NET, MVC, Visual Studio, SQL Server, Access, Word, Excel, Mahjong, Solitaire, ...

1 solution

In the OnSelectedIndexChanged all you have to do is call DropDownList.DataBind() and the SelectMethod will be executed and the data will be loaded in the DropDownList
