Question

I’m not sure what this functionality is properly called. But I have a single-line text box in an asp.net gridview. When a user clicks on that textbox, I want a larger, multi-line textbox to pop-up, so they can see the entire contents and edit it. This expanded view would go away once the focus moves to another control.

Is there a control out there that allows for this? If not, how could I go about implementing one?

EDIT: I’m looking for similar function to how the TextBoxCalendar Extender works, but instead of a calendar, I’d like a multiline textbox to pop.

This blog post has an elastic textbox that uses jQuery. According to the author,

…when the TextBox gets the focus, it will expand to a specified height and width and then when it loses focus it will contract back to it’s more compact size.
