CheckedChanged event isn't in classic asp.

I inherited a project that was configured to run a file based Web Site using the ASP.NET Development Web Server. I want to switch this over to run using IIS. I have been looking through the project options but I cannot find how to go about switching this without creating a whole new project. Am I missing something?
Regards,
Jeff

Right click Website->Properties->Web->Select Use IIS Web Server Radio button and provide the URL.

I don't have that option... is this only in VS2008.
|

It was for VS2005 but you should be able to find that setting somewhere in Project Properties page.

The topic subject mind sounds familiar to some of you.
My problem
An Asp.NET website (3.5) with AJAX has a USER CONTROL.
This Control exists of a Label and of a DropDownList.
In my WebPage I consume the control and that works.
In the control I have stated:
<code>
public event EventHandler SelectedIndexChanged;
protected void Page_Init(Object sender, EventArgs e)
{
this.SelectedIndexChanged += new EventHandler(DDL_Osic);
}
protected void DDL_Osic(Object sender, EventArgs e)
{
if (this.SelectedIndexChanged != null)
this.SelectedIndexChanged(sender, e);
}
</code>
and in the ASPX of the User Control
<asp:DropDownList runat="server" ID="ddlTBM" CssClass="PromptValue" Width="100%"
AutoPostBack="true" OnSelectedIndexChanged="DDL_Osic"/>
In the Webpage it says in the aspx
<uc1:PromptSelecteerTBM ID="PromptTBM" runat="server"
OnSelectedIndexChanged="PromptTBM_OSIC" />
In the codebehind of the webpage:
protected void PromptTBM_OSIC(Object sender, EventArgs e)
{
LaadTBMZones(0);
}
And now the problem:
What happens that if I change the selection of the DropDownList the event of the usercontrol is fired, it goes to the method in the webpage, than returns to the event/method of the usercontrol and returns to the codebehind of the webpage and then back again...and so on
What did I do wrong? How to stop this loop?
|

SelectedIndexChanged triggers DDL_Osic, which calls SelectedIndexChanged, which triggers DDL_Osic, and so on... that's your loop.
I really do not understand why you add the handler in Page_Init and in aspx, either...
(i've tried posting a similar message a minute ago but i think it crashed, sorry if it actually had posted it and you're gonna see it twice. Though if it crashes again, i'm not gonna type it again 
|

Hey Greg,
I added the handlers to both sides because I saw plenty of examples with this. Well if there is 1 too many, which should be removed?
|
|
|
|
|
Don't worry about that, honestly. Whichever you get rid off makes no difference, it's still gonna trigger.
Worry about your handler though and get rid of the part that says:
this.SelectedIndexChanged(sender,e);
in your DDL_Osic method, though, and add some proper logic to what the program should do at this point. As in what should happen, when the selection has been changed. If DDL_Osic triggers, means it CAUGHT the event. No need to call it again
|
|
|
|
|
the point is this:
As soons as the usercontrol ddl has changed it selectedindex the webpage should call a method to fill a Gridview which is outside of the usercontrol but in the page.
So if I remove the this.SelectedIndexChanged(sender,e); How can I fill the gridview autoside the ussercontrol with data?
|
|
|
|
|
This is what i'd do.
Forget about the code behind of the UserControl, make that Dropdown public in the usercontrol class and on the main aspx add the handler, (Page_Init, Page_Load):
private void Page_Load()
{
(yourusercontrol).(YourDropdownInUserControlId).SelectedIndexChanged += new EventHandler(s_SelectedIndexChanged);
}
private void s_SelectedIndexChanged(object sender, EventArgs)
{
}
Hope this works for you
|

Yeah,
this even works better!
This component is used over several pages in the system and only in 1 page it should do OnSelectionChangedIndex event. So the other pages have no interference with this.
COOL and many thanx
|
|
|

FOUND IT
just remove
//if (this.SelectedIndexChanged != null)
// this.SelectedIndexChanged += new EventHandler(this.DDL_Osic);
in the page_init in the user control. That was the devil that bit me this afternoon!
thanx for your input.

How can I quit completely from master page. End all sessions and go back to login page
Sessio.abandon() or Session.Clear seem not working
|
|
|
|
|
Hi,
Use Session.Remove("SessionVariable")
and check on master page load, if session is nothing then redirect your
login page

Fine Fine . What I did was to set a logout immagebutton to have a postback Url to be
"master page" and at the same time code click event to abandon session. I have noticed that
it did not recognize the coded click event but the postback. so it works after removing postback Url, but i think
such like confusions Microsoft should address instead of using common sense.

Hi,
some time i get this error :
Exception: System.ArgumentException: Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %>

Can I suggest that if you take the advice already given, you make sure you fully understand its implications. There are security considerations here.
