Help with Dropdownlist

[niju]

Hi there,
My aspx page has two dropdownlist controls Dropdownlist1 and
Dropdownlist2. Dropdownlist2 is populated when
Dropdownlist1_SelectedIndexChanged is fired. Now my problem is:

When I use a keyboard and tab to Dropdownlist1 and select the first
item, Dropdownlist1_SelectedIndexChanged is fired. I never get chance
to select second item from the Dropdownlist1.To prevent this i am using
"System.Threading.Thread.Sleep(200)" on
Dropdownlist1_SelectedIndexChanged.Is it safe to use Thread.sleep on
dopdownlist1_SelectedIndexChanged event.


Many Thanks
Niju

Hi Niju,

Rather than build in delays, you might want to analyze how Andy Smith
accomplishes this with client-side script using his free control:
