A Razor page can be returned by any number of methods in a controller, so long as every one of those methods understands that that page can only accept one particular type.
If you've got multiple methods that are sending data to a view page, each method is going to need it's own Razor page, each defining what type it's looking for to match the data passed to it.
You're not going to get away with a single Razor page handling all kinds of data types.
Now, if you're trying to get multiple controller methods to all send data to the same page being returned, only one method can send data to the Razor page (view).
To get multiple methods to generate data, the method that returns the View is going to have to call the other methods and get the data returned by each. It can then wrap all those pieces of data in a single class you'll have to write, and assemble all that data into a single instance of this container class, passing it to the View.

Ok, that makes sense. I come from more of a data science background using more functional programming/scripts, and am trying to implement a semi-functional dashboard of sorts with some signalr components. So if I want to return several boxes that display string results, that is doable, but if I also want some graphical output as well, I am barking up the wrong tree?
Also, I don't suppose the container class return View() would look like return View(context.GetValue1, context.GetValue2, etc...)

No, you can only send one model to the view. So you have to create a class that holds all of the data you need to send to the view, even if that data comes from separate methods. You then call each of those methods and populate the instance of the container class.
You THEN send that container to the View.

If your model is object (sender), object (argument), can you recast them in the view?

Huh? Are you asking what happens if you try to cast an object to a defined type?
|
|
|

The guy wants a "single model": you said "model int"; what about "model object object" and I cast the second based on the type of the first.
Never cast a sender as a button in a click event?
(Huh?)

Yes, I have. What you posted before didn't make sense and was quite a bit beyond "Sending data to a View 101".

Crap. It's been a while.
If the data to be passed is nothing but a string, you can't do that. Everything else is OK.

Hello ! ^^
I'm desperately trying to recover the image to the third second of a video, in MP4 format as Bitmap.
I need this to analyze the image and get some information from it.
Thank you for the person who will take the time to answer me and guide me.
Code for the moment :
foreach (string file in filePaths)
{
}

This may sound silly, but if what you want is just a single image, why write a program to do it? Why not play the video on your PC, count to three, then press the PrintScreen key. After that, use an image processing tool, e.g. MS-Paint, and paste the image in it.

You go frame-by-frame; using the frame rate to calculate "time in".

How to connect the device with the C # language

We can't answer that.
This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with. So we have no idea what kind of device you are talking about, how it physically connects to the computer, or anything else about it.
That's like asking "how do I get to Mike's house?" without specifying the which country "Mike" lives in, much less what his full name might be!

Impossible to answer. You haven't specified what the "device" is, so it's impossible for ANYONE to tell you how to "connect it with C#". You've left out every possible detail you could to describe the problem.
Asking questions is a skill[^] that you seriously need to work on.

As specified in the documentation; if you want to write a device-driver, then the answer is no.

Have you tried switching it off and on again?

I created a UserControl with 5 buttons: New, Edit, Delete, Save, Cancel. All buttons have functions associated to them, programable by the user. Normally the 3 first buttons are enabled and the 2 other are disabled. When the user clicks on New or Edit, the 3 first buttons become disabled and the 2 others, enabled. When the user clicks on Save, or Cancel, it returns to the original state. It's working fine, but there is an issue.
In an application, when the user clicks on the Save button, the program must first verify if the fields are all filled. If yes, OK. But if not, the function should do nothing. So, what I need is a way of, in the main program, test the fields and pass this information to the control. But I don't know how. I tried to create a funtion in the control type virtual and in the main program I tried to create the same function with override, but it didn't work. Can anyone help me?
Thanks.
