How to use FindByText property of dropdownlist where text to find is in a textbox? i.e

if i write,
dropdownlist1.I tems.FindByText (" ' "& txt1.Text &" ' ").Selected = True

i get error
System.NullRefe renceException: Object reference not set to an instance of an object

Try putting txt1.text into a string, eg myString, writing it to ensure it has a value and then use:

dropdownlist1.Items.FindByText(myString).Selected = True

myString = txt1.Text
dropdownlist1.F indByText(myStr ing).Selected = True
