I'm some what new to Generics and I can't figure out why the following doesn't work.
I have an extension to IEnumerable<T>
, called Grid and it looks like so
public static class IEnumerableGridExtension
{
public static HelperResult Grid<T>(this IEnumerable<T> gridItems, Action<GridView<T>> thegrid)
{
........
}
}
Say, I have a variable in my razor Model called "Products" and it is the type List<Product>
, so I tried to do
@Model.Products.Grid<Product>(grid => {
...
});
I get an error:
Cannot convert method group 'Grid" to non-delegate type 'object'. Did you intend to invoke the method?
with @Model.tasks.Grid
underlined in red.
The funny thing is, Visual Studio compiles, everything is fine. Of course, if I simply do
@Model.Products.Grid(grid => {
...
});
It's all fine.
The Razor parser is interpreting < and > as normal HTML tags. You can avoid the problem wrapping the call in parenthesis:
@(Model.Products.Grid<Product>(grid=>{
...
}))
You can find additional info here: How to use generic syntax inside a Razor view file?
