TextBox events

[E11esar]

Hello there.

I am writing an ASP.net page using C# and I want to invoke an event that is called when I enter a reference number in the TextBox. This event will go on to cause a corresponding ListBox to be populated.

I thought the OnTextChanged would be a suitable event but this is not happening for me at the moment. I don't want to use a Button and hence a click event in that way, so can anybody think of a suitable way to do this please?

I am thinking possibly of a JavaScript function and then add attributes to the TextBox to call this method but again, I'm not sure what event this could be coded towards..?

Thank you.

Solution

Hello there - I have been able to solve this one now.. I originall felt that the OnTextChanged event is the correct one and yes, I did have the AutoPostBack set to "true" but it wasn't hitting the event for some reason.

I've booted my laptop as an update was installed and now all of a sudden it is working.

So I'm not sure as to what was amiss earlier with this one.

Thank you.
