Question

I’m looking for the best solution to update a text box text value to DB while the text box still contains the focus. I don’t want to do it on TextChanged or Leave events taking in consideration that I need to query the actual value from DB even when the text box contains the focus and the user stopped typing.

Answer 1

Every X seconds (Using a Timer)

    if (txtMyTextBox.Text != previousText)
       previousText = txtMyTextBox.Text;
    else //(if the text is the same before X seconds)
         //User has stopped typing! Save it to the database
         //Stop the timer!

TextChange event of txtMyTextBox will check if the Timer is stopped, and if yes, restart it.

X is the number of seconds after, if no input is received, you decide that the user has stopped typing.

Given there are a lot of text boxes, this can get very cumbersome :S So I agree definitely there should be a better way.
