✅ Type Casting

Hi, Just wondering how I would type cast the object 'control' to the type 'telerikslider'?

var foo = (TelerikSlider<>)control; you'd want the variable to be initialized outside of the foreach though

use pattern matching

if(control is TelerikSlider<> telerikControl)
{

}

if(control is TelerikSlider<> telerikControl)
{

}

TelerikSlider<> foo;
foreach(...)
{
    foo = (TelerikSlider<>)control;
}

TelerikSlider<> foo;
foreach(...)
{
    foo = (TelerikSlider<>)control;
}

ish i had no idea you could do this this is excellent don't monkaS me 😛

Thanks for the help. Learned 2 different ways. Even better!

Won't work for a generic without a type

TSJN•2y ago

As in the pattern matching method?

TheBoxyBear•2y ago

You can get a Type object with typeof without a generic but if you want to cast in any way, you need the generic Not sure even == typeof(TelerikSlider<>) would work as no object can be of that type You need the type that goes in <>, unless there's a base TelerikSlider type

That's what ultimately led me to here as every example is with a generic

TheBoxyBear•2y ago

Check the metadata or docs to see if it derives from TelerikSlider and if so, use that If not, you'll need to make the context itself generic and use T in TelerikSlider In that latter scenario, the caller is responsible of providing the generic type Though not sure if you can do that in cshtml

Turns out it needed an argument in the angle brackets of the type. Question now is, how do I store/save the value to the SavedValue field in the UserSetting class?

TheBoxyBear•2y ago

Yes, that's the generic type
