ASP.Net dropdownlist post back on lose focus?

Right now I'm using the OnSelectedIndexChanged event to trigger a post back and update some other fields in the form. That works fine. But I would like it to do the post back when the drop down list loses focus, rather than on every change. The problem is, when someone selects the list, then types a number, it will change with every key stroke they press, and that will trigger the post back before they get to the value they are trying to type.

Is this possible?

Try this.

ddlDropDown.Attributes.Add("onblur", "__doPostBack('ddlDropDown','');");

I have not tested it, but I believe it will work - or I hope.

The JavaScript event for something losing focus is called onblur.

Use Attributes.Add() in server-side code to add the function name to be called. You can then trigger the postback from said function.
