Checkbox on change update

[nona]

hi i need help on this problem, but please don't laugh at my question, i'm a newbie on this .net programing

can some one tell how to make this thing work :

Private Sub checkbox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles checkbox1check.CheckedChanged
DropDownList1.Enabled = Not DropDownList1.Enable
End Sub

when i brows the pages and i change the check condition on the checkbox1, the dropdownlist1 still working

in my thinking if i change the checkbox1 condition, the dropdownlist1 will be disabled. but in the web pages this dropdownlist still working

please give me a way how to make this work. thx

DropDownList1.Enabled = Not DropDownList1.Enable

this should just be:
DropDownList1.Enabled = False

Hope this helps. If not, I guess I didn't understand the question correctly!

yes i understand that script, i think my script is the same thing if the initial condition of my dropdownlist.enabled properties is "true"(not "true" = false).
the real problem is on the script, but why is that my project in the browser is not changing following the change on the dropdownlist.enabled properties (the web display is not refreshed on the current condition)?

sorry, you need to change the PostBack property of the check box to be true, this way when they check the box, it refreshes the page with whatever new properties you set in your program.

hello

if you want to do any operation on web page (.aspx) page with out re loading

the only option is using script language.if you are familiar with java script its

good else there are many third party tools which uses ajax just try with them

DropDownList1.Enabled = Not DropDownList1.Enable

this should just be:
DropDownList1.Enabled = False

DropDownList1.Enabled = Not DropDownList1.Enable

this should just be:
DropDownList1.Enabled = False

i allready try the script and work well, because i want to make the condition change opposite the current condition, not to make it allways false.
