VS 2010 Dropdownlist Doesn't Trigger Event
Mar 17, 2011
I populate the items to the dropdownlist with values from a database. I use the .text and .value properties. It comes out right in the list. However when I try to make a button visible when selectedindexchange or selectedtextchange, nothing happens. Therefor I made the button always visible (because itīs the "add" button to the database depending on the selected item). When clicking Add I realize itīs the same value being sent to the database everytime, ie the first value of the list. So Iīm thinking the selected... events isnīt working. Do you know what Iīm doing wrong?

Trying to get a helloworld web application up running in Visual Web Developer 2010.
Now I created a new project with Home controller and two default views (index and about).
Then in the index view I added a button and a textbox...double clicking the button creates a handler in the view, but it's never called...what am I missing?
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>

I have a LoginView in my APS.NET application with AnonymousTemplate and LoggedInTemplate. I've put LoginStatus control inside LoggedInTemplate but it doesn't work as expected.
Here's the code
<asp:LoginView ID="LoginView1" runat="server">
<AnonymousTemplate>
<asp:Login ID="Login1" runat="server" OnAuthenticate="Login1_Authenticate"
DisplayRememberMe="False" PasswordRecoveryUrl="/"
DestinationPageUrl="/">
</asp:Login>
</AnonymousTemplate>
<LoggedInTemplate>
You are logged in as
<asp:LoginName ID="LoginName1" runat="Server"></asp:LoginName>.
<asp:LoginStatus ID="LoginStatus1" runat="server" LogoutAction="Redirect"
LogoutPageUrl="/" onloggingout="LoginStatus1_LoggingOut" />
</LoggedInTemplate>
</asp:LoginView>
All event handlers are correctly defined in code behind file.
The problem is that if user logs in he will see his user name with logout link from LoginStatus control. Clicking the logout link takes the user back to login form (both login and logout form are part of the same user control) but if I refresh the page the user is still logged in.
I've noticed that if I move LoginStatus control outside the LoginView then logout process works as expected. I've also noticed that when LoginStatus is inside LoginView then it doesn't raise a loggingout event.

i am currently developing an asp.net project. there is a previous, next, and cancel button that the user can utilize, but the problem is that everything is broken into controls so that if they hit the browser's back button it will reset everything and take them to the very beginning. i would like to capture the onbeforeunload event and trigger the previous button click event (i.e. treating navigation like clicking the previous button).

I am trying to attach a server-side event to lookup the city/state for the user-entered zipcode in a field like the one below.
<asp:TextBox ID="TextZipcode" runat="server" CssClass="inputtext" Columns="10" MaxLength="10"></asp:TextBox>
Since there is no lost focus event to capture, has anyone had any luck getting this to work?

I have searched around but unable to find a solution that will work. I have a link button that is created dynamically during the page load. It is given an ID (obviously). There is a script manager on the page. I have the controls added to a panel in the updatepanel (updatePanel1). There is a dynamic label that is also created with each link button. I can get a response from the linkbutton click event during a postback on the second time clicking the linkbutton, but I am getting a complete postback instead of the asyncpostback for that control. During the creation of the dynamic linkbuttons, I am also creating a dynamic trigger for each button and adding it to the updatePanel1. The Click event is not firing the method without doing a complete page postback.

I have an UpdatePanel on the page which I'd like to trigger using javascript.First of all my code perfectly works if it's in a website not being inheriting from a masterpage. Now when you put exactly the same code into a website which inherits from a masterpage, the UpdatePanel wouldn't get fired anymore.
Here's the code (.aspx) [Code]....

I have 3 gridviews in one of my web page. I have simplified the system structure in the image below(further description will be stated below the image): As shown in the image above, the web site(presentation layer) will work closely with the Business Logic layer(BLL) and Data Access Layer(DLL). ObjectDataSource control will be the middle man to select, update, insert and delete the data in the gridviews. During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.
The data in the returned datatable will be filetered by type using RowFilter method and stored into the 3 dataviews. Each dataview will act as the datasource for the 3 GridViews respectively, and therefore I specified the datasource programatically instead of setting the datasourceid for each gridview.
dataview1 = New DataView(dtSelectedTable)
dataview1.RowFilter = "Type='1'"
GridView1.DataSource = dataview1
GridView1.DataBind()
dataview2 = New DataView(dtSelectedTable)
dataview2.RowFilter = "Type='2'"
GridView2.DataSource = dataview2
GridView2.DataBind()
dataview3 = New DataView(dtSelectedTable)
dataview3.RowFilter = "Type='3'"
GridView2.DataSource = dataview3
GridView2.DataBind()
However, the Update(command button) and Delete(template field) doesn't work, the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource. I couldn't figure out why, hope that someone who have come across the same problem couldn't provide some guidance.

I am writing Watin test in MVC Asp.net app. I mvc app, all input are wrpped with form and every time an input or textarea is changed their form gets submitted by jquery like code below:
$("textarea", context).change(function() {
$(this).parents('form:first').submit();
});
This is perfect when changes are done by keyboard. However this doesn't trigger the form submit when input/textarea are changed by Watin TypeText() method. I tried to call Change() and Blur() events by Watin and also tried PressTab() with no luck.

I have a text box and ajax autocomplete control extender in my Master Page that it is not working at all. When I type some characters on the text box it doesn't trigger the autocomplete. I have a web service that contains the function code. I est my code on a single Web Page (No Master Page) and it works perfectly. Also, it works fine if I include the text box and the extender on the Content Page instead of on the Master Page. It is important to keep the text box in the Master Page for me. I am using Visual Studio 2008 and ASP 3.5. MASTER PAGE.

I have a dropdownlist (dr1) that is supposed to trigger the update of dr2 without affecting dr3. The problem is that dr1 triggers the update, but does not go into dr1_SelectedIndexChanged. I know that because the label does not change and that the pause does not happen
Here is my HTML code:
<form runat="server">
<asp:ScriptManager ID="sm" runat="server" />
<asp:UpdateProgress ID="UpdateProgress1" runat="server" DisplayAfter="5">
<ProgressTemplate>

I have a set of accordian divs (powered by the prototype library) in an asp.net page. I would like to save the state of the accordian, so when a postback event occurs, the same div is open rather than reloading the page entirely and opening the default div.
My plan was to set a page control value with the ID of the open div using the div's toggler click event function, and then fire a click event after postback calling that same div (using the value of the control holding the div ID) as the target. I'm not sure how to fire a javascript click event from vb.net however, and this sure seems like a lame workaround.
1) can you tell me how to fire a javascript click event from the vb.net codebehind page
-or-
2) is there a more elegant way to do this?

The ItemCommand of the ListView object triggers great, without URL Rewriting, (powered via urlrewriting.net)
Private Sub ListView_ItemCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewCommandEventArgs) Handles ListView.ItemCommand
End Sub
With the URL ReWritting turned-on the event does not trigger.Could you please point me a trick to make them both work?

I created a MultiHandleSliderExtender on a web form. All works well with updating the two textboxes with the value. The problem is that when I switch to designer mode, I get the following error:
The code is as follows:
[Code]....
[Code]....
[Code]....
The control works and the 2 text boxes get updated, but I tried putting in an update panel with a trigger on mh_1_BoundControl but it never fired. I removed it thinking that was the cause of the error, but no luck.
Now when I add another sliderextender below it for a different value, the code throws an error:
Microsoft JScript runtime error: Sys.InvalidOperationException: Type AjaxControlToolkit.SliderOrientation has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.
I found this example on this site and tried implementing it but to no avail.

I need to run a SELECT box [on]change handler after changing the selectedIndex.
I see the selectBox._events['change'][0].handler() method added by $addHandler, but what is the ASP.NET Ajax way to raise it as an event?
The backup plan is to set sel.onchange directly and skip ASP.NET Ajax events completely.

User selects a date from the date-picker and the date is put into a text-box.
But when i choose a date some date should check another text box date and give me the difference. The selection-change event does not fire (as expected).
protected void dtpleavestartdate_SelectionChanged(object sender, EventArgs e)
{
string a = "NO CHANGE";
a = a + dtpenddate.SelectedDate.Subtract(dtpleavestartdate.SelectedDate).ToString();
Response.Write("<script>alert('" + a +"')</script>");
}

I have an asp:TextBox with asp:RegularExpressionValidator to validate if it's a number. Obviously an onchange event will be attached to this textbox while rendering. Also I add a change event at $(document).ready to make some calculation when the value is changed.
<asp:TextBox id="myText" runat="server" />
<asp:regularexpressionvalidator id="myRev" ControlToValidate="myText" runat="server">*</asp:regularexpressionvalidator>
$(document).ready(function(){
$('[id$=myText]').bind('change',function(){
//do something........
and found that all of event.fromElement,event.toElement,event.srcElement are null which causes the exception.

I have the following situation:
Updatepanel
dynamically loaded Usercontrol
Button
UpdatePanel2
I am loading a Usercontrol with another Updatepanel inside of it. Now in this usercontrol, i have a button which is registered as an async postback trigger for the 2nd Updatepanel. However when I click the button, nothing happens. While debugging, it does not even step into the Click event of the Button which sits in the usercontrol of course. The Parent Updatepanel ist set to Updatemode conditional and hildrenAsTriggers="false". The nested UpdatePanel2 is set to Updatemode=Conditional. I just want the Parent Updatepanel to do nothing and the button to fire its event so that I can load some data in the nested updatepanel.
