c# - BackgroundWorker multithread access to form -


I am using 5 backgroundwork objects running at the same time for a specific purpose, and all of them Only the labels have to be changed. How can I go about doing this?

How do I modify the form with more than one formulas? And how can I do this if I want to change a public string?

Use the control. A representative 

  label4.Text = Instead of saying "hello", in your background worker thread;

say 

  label4.Invoke (new action (=) {label4.Text = "hello";}));

{} executes everything on the control thread, so you avoid the exception.

This allows you to make arbitrary changes to your user interface from a instead of progress by reporting instead of progress.

I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
