Help: Events not executing

[Michael]

Hi Everyone,
I'm having a problem trying to get the program to execute the
SelectedIndexChanged event for a Dropdownlist (Combobox). I double clicked
the control to get the event in the Code-Behind file. I have the following
declare :
Protected Sub cmbPORequests_SelectedIndexChanged(ByVal sender As Object,
ByVal e As System.EventArgs) Handles cmbPORequests.SelectedIndexChanged
if cmbPORequests.SelectedValue > 0 then
BindGrid(cmbPORequests.SelectedValue )
end if
End Sub

When I select a new item in the control, the event is not executed. I even
tried to add the following to the markup:
<asp:DropDownList ID="cmbPORequests" runat="server" DataTextField=""
OnSelectedIndexChanged="cmbPORequests_SelectedInde xChanged"
DataValueField="" Style="left: 298px; top: 109px" Width="175px">
</asp:DropDownList>
This didn't work either. One question I did have was: Do I need to set the
AutoPostBack property to true? From my reading I get the feeling I don't need
to, but wanted to make sure. Any comments would help. Thanks.

Hi Everyone,
I've done some testing and have found that if I have AutoPostBack set to
true, I get the event, BUT ONLY AFTER I click a command button. It seems that
it has put the events in a queue. If I turn off AutoPostback, the event for
the combo is never executed. I need the form to respond right away to the
SelectedIndexChanged event so that it can load the correct data in a grid.
Thanks for any advice.

AutoPostBack works if javascript is working in the page. If not, then the
form has to wait until the user has hit the submit button.

Hi Brock,
Thanks for the reply. I'm not sure if I got all the setting right, but I
went into the Intoernet options > Security
I enabled "Allow scripting of Internet Explorer Webbrowser controls"
Already enabled "Scripting of Java applets"
Java permissions = High safty (Does this one need to be changed)

I made sure of the above settings and ran the project, and it didn't work
again, at least not when the I select an item from the dropdownlist. Only
after clicking on one of commad buttons. What do you think. Thanks again so
much for the reply.

What happens if you create a new blank page, drop a server dropdownlist on
it, double-click on it to get to the code behind, and put in some code for
the selectedindexchanged event. Does this work?

Hi Jeff,
I created a new project, added a master page and a content page and on the
content page I added a dropdownlist. For the SelectedIndexChanged event I
just added a msgbox call. It works with the AutoPostback set to true. What
does this you. Is there something in the web.config file that may need to be
changed? Thanks again for the help.

By the way, I'm using Visual Studio 2005 if that makes a difference.

Thanks for the help. I have it working now. Installing java may have
corrected something. Its working great now. Thanks for all that helped.

I'm confused. Is it working, or not?

When I do this, I don't have to set anything..it just works. And keep in
mind you can't call MsgBox, it runs on the server!
