In my application i have placed one label in the update panel and in triggers one textbox and one dropdownlist.
<asp:UpdatePanel ID="TestPanel" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Label ID="lblTest" runat="server"></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="txtTest" EventName="TextChanged" />
<asp:AsyncPostBackTrigger ControlID="ddlTest" EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
In the textbox if i gave any wrong input then i am displaying the error message with label "lblTest".The error is displayed in the label sucessfully but when i am selecting the ddlTest dropdownlist the error message is disappeared.

I have got a query regarding the usage of delegate in usercontrols. The scenario is I have got a user control which acts as a footer
on all the pages, It has the following place holders : Email, Print, Logout.
What I want to acheive here is when the customer logged in he/she has certain feauture's on the website for instance his/her personal diary,
dieting charts, birthday calender etc. I have figured out a way to create pdf's of each summary , what I am looking for is how to use the usercontrol
for instance when the customer clicks on the email place holder on certain page which is in the footer usercontrol, the following place holder should send
an email with the pdf file of that particular page attached to the customer. I came to know that delegate is the best way of doing it, but I cant find any specific tutorial on it.

've recently set up an ASP.net site (not using MVC.net) to use URL Routing (more on the code below) - when using user controls on the site (i.e I've created a "menu" user control to hold menu information) the page_load event for that control will fire twice when URLs have more than one variable passed over.
i.e.
pageName/VAR1 : will only fire the page_load event once.
while
pageName/VAR1/VAR2 : will fire the page_load event twice.
*Multiple extra VARs added on the end will still only fire the page_load event twice*.
Below are the code snippits from the files, the first is the MapPageRoute, located in the Global.asax :
[code]....
Note, that when I'm just hitting the page and it uses the default values for items, the reloads do not happen.

I have a masterpage setup, with a pageLoad in the topmost masterpage, which calls pageLoad2 for nested masterpages which calls pageLoad3 for content pages.
In my content page I have a jquery click event and in my nested masterpage I have a web user control.
Whenever I use the user control in the nested masterpage, it rebinds the click event in the content page (undoubtedly because the pageLoad3 is called again), but this makes the click event fire twice on a single click. The problem gets worse the higher up masterpages you go (eg. fires 3 times if user control from topmost masterpage is called).
how to make sure it only binds the jquery events once?

I have an application where I want to send an email reminder for an appointment 24 hours prior to the event. Users would log in and insert appointments. I would think I would want a background thread running on the server that would regularly check the database (say every hour) and generate an email if there is an event is due within the next day. From what I have read it seems like a Web service might do this. I guess I have a few questions
1) am I on the right track - is this an application for web services
2) can anyone point me to a good resource which can help me create the web service I would need. I would prefer if it is in VB and not C#.

In the code below, I learned to use a trigger to either display or hide a panel (pnlMaidenName_Edit) when the user clicks on either side of a radio button (rblGender_Edit). The problem now, however, is that whenever rblGender_Edit is assigned a SelectedValue of 2 for female, the hidden textbox displays in a location way out of position from where it should be. Also, the radio list button displays again, as shown in the following screenshot, near where the textbox now displays.

I've got a page with two ContentPlaceHolders. In first there is UpdatePanel with GridView. In second I located DropDownList which is trigger for UpdatePanel.
<asp:UpdatePanel ID="stanUpdatePanel" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true" >
<ContentTemplate>
GridView & other stuff
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ATDropDownList"
EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
Running the page causes error: "Control with ID 'ATDropDownList" could not be found for the trigger in UpdatePanel". I thought it was because the ATDropDownList is located inside ContentPlaceHolder. So I changed ATDropDownList's ID to UniqueID as follow:
<asp:AsyncPostBackTrigger ControlID="ctl00$ContentPlaceHolder2$ATDropDownList" (...)>
Everything works good, but I want to change it from page's code-behind. I tried to put

somewhere in code, but without luck so far.

I have a form which inserts data in DB on Submit button click but the problem is when client click the button multiple times its sends multiple create requests means multiple button click events for the same time of same data, which must not be.
I tried to disable the button when client click the Submit button first time but after this it does not call server click event handler or not fire the server click event once it got disabled.
How to handle this multiple click problem..
I used the following code to disable the button

I have an update panel on the parent page into which I load and remove a set of user controls.
Now, when a button is pressed on the user control, the events are fired but there are no changes in the page. For example:
Main Page
<updatePanelMain>
<childcontrol1>
<childcontrol2>
etc
ChildControl.ascx
<update panel 1>
<panel1/>
<panel2/>
<btn1/>
etc
So, if I want to hide panel 1 when btn1 is clicked etc, I simple use code such as panel1.visible = false.
All this gets executed but nothing happens to the page.
<asp:UpdatePanel ChildrenAsTriggers="false" UpdateMode="Conditional" ID="updatePanel"
runat="server" EnableViewState="true">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />
</Triggers>
<ContentTemplate>
However, when I use placeholders instead of update panels in the child controls, I dont face any such problems.
<asp:PlaceHolder ID="placeholderTypeOfInvestor" runat="server">

My issues here is that this does not compile. I get "A control with ID 'LinkButtonRemove' could not be found for the trigger in UpdatePanel 'UpdatePanelFiles'." What I am trying to do is have two buttons in the item template. One that updates just the ITEM and one that updates the entire DataList. "LinkButtonRemove" is what I want to update the entire datalist. Any ideas on why this isnt working? Or how to do what I want to do?
THE SHORT VERSION:
UPDATEPANEL1
-DATALIST
--ITEM
---UPDATEPANEL2
----CONTROLS
I want one control to update the item updatepanel only and the other to update the entire datalist.
<asp:UpdatePanel ID="UpdatePanelFiles" runat="server" ChildrenAsTriggers="False" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="LinkButtonRemove" />
</Triggers>
<ContentTemplate>
<asp:DataList ID="DataListFiles" class="MediaManagerDataList" runat="server" ItemStyle-BackColor="#ffffff" AlternatingItemStyle-BackColor="#E7F4FF" OnItemCommand="DataListFiles_ItemCommand">
<ItemTemplate>
<asp:UpdatePanel ID="UpdatePanelItem" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<div class="item">
<asp:LinkButton ID="LinkButtonRemove" CommandName="remove" runat="server">Remove</asp:LinkButton>
</div>

I have a gridview with multiple checkboxes, sometimes 40+. I want the checkboxes to call a .net function in the code behind when clicked. Normally this would be simple if the checkboxes were outside of the gridview. But because they are in the gridview and I don't know how many there are, I don't know their id's before runtime.
I am at the point right now that when you click a checkbox, a jQuery script returns the id and value of the checkbox. Unfortunately, I don't know how to pass the value to a function - that will in turn update another gridview. AFAIK my only option is to get the id's of the controls (checkboxes) before page load and to programatically add then to the update trigger portion of the update panel. Is there any other way to say 'if any checkboxes are clicked, run this'?
