Updating textbox asynchronously

The user can enter new numbers in the textbox and after doing this when the textbox loses focus I need to do the following asynchronously. I want the easiest and fastest way to do this. I am thinking about using an updatePanel but also thinking about if I can do this async way by creating my own javascript xmlHttpRequest object, but in the end leaning towards the update panel because I will need to update one or two adjacent fields in the repeater row based on what the user enters.

I know this might sound wild: but is there a way to update the db once the user is done typing in cents,. The sample contains a grid view which displays the customer data from Adventure work database. The customer information is retrieved by clicking on the customer Id which is populated in the dropdownlist.

I just knocked together some code on another thread.. This Task returns stuff back to the UI thread when you await it. So calling that: Textbox. What that does is sets your text on the textbox and cranks up another thread - a Task. It goes off and does it's stuff. When complete control returns to the statement after the await. Something like: Textbox. I inherited this program, so I will refactor it to use a TextBlock.

Run will queue the operation to run on the thread pool and will return a Task object. An important thing to notice here is the use of a Dispatcher. WPF requires all interface updates to be done from a single thread: the UI thread, which queues work items inside an object called a Dispatcher. If you try to update the interface from a different thread then the UI thread you will get an System.

InvalidOperationException : The calling thread cannot access this object because a different thread owns it. Threading; using System. QueueUserWorkItem this. Set hasSent field.
