Question

In my app I’m saving data to my database (SQLite).
I don’t want to block my UI so I save the data in diffrent task

            await Task.Run(() => this.SaveTracks(books, filesCollection));

I get TextBox from my dictionary with data

TextBox tmpTextBox = parseData["title_" + i] as TextBox;

When it wasn’t in diffrent Task it works great but when I’ve set in with Task.Run I get Exception that I can’t use it cause I invoke element in diffrent thread. How can I not block my UI by doing it in diffrent Task and get data from UI elements in main Thread

Get the TextBox.Text value before you start the Task and pass that value as an argument.
