how can i update an update panel from a button within an update panel
i.e. how can i get the below to work? a the mo i get
System.InvalidOperationException: A control with ID 'SaveTemplateLink' could not be found for the trigger in UpdatePanel 'UpdatePanel2'.
[Code]....
Cannot unregister UpdatePanel with ID 'UpdatePanel2' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.
Parameter name: updatePanel
Overview
I have 3 update panels on a page, each of them have UpdateMode="Conditional".
UpdatePanel1 contains listbox1 (AutoPostBack set to true) which is populated on pageinit from the DB.
UpdatePanel2 contains listbox2 (AutoPostBack set to true), this panel has AsyncPostBackTrigger set to the SelectedIndexChanged event for listbox1 in UpdatePanel1.
UpdatePanel3 contains textboxes that will hold the details once an item has been selected from listbox1 and listbox2, this panel has an AsyncPostBackTrigger set to the SelectedIndexChanged event for listbox2 in UpdatePanel2.
In the codebehind, the SelectedIndexChanged event for listbox1 populates listbox2 and the SelectedIndexChanged event for listbox2 populates the textboxes in UpdatePanel3.
The problem
When the page loads listbox1 is correctly populated, I select a value from listbox1 and listbox2 is populated, great, no problem so far. When I then select a value from listbox2 the SelectedIndexChanged event for listbox1 is firing, I assume that as this populates listbox2 again it is clearing the selected value for listbox2 as the SelectedIndexChanged event for listbox2 is not firing.
How do I stop the SelectedIndexChanged event for listbox1 in UpdatePanel1 from firing when I select a value from listbox2 in UpdatePanel2 ?
I have a formview in Edit Mode, within an update Panel all and these arewithin a Modal Pop Up extender.On clicking Formview Update button, I want an image to appear within the pop up.I have put the image within another panel1 and runat server.For some reason the image is not showing on clicking update button.

I have a page with 2 update panels
UpdatePanel1 contains a gridview1 and a standard panel, pnlForms. gridview1 has a linkbutton which is processed in the gridview1_rowcommand
UpdatePanel2 has gridview2.
There is also a Submit button that isn't in either UpdatePanel but may be a candidate to go into its own UpdatePanel. The Submit button is a trigger for both update panels
The behavior I would like is:
1-Initially, all visible except pnlForms and Submit button 2- When linkbutton in UpdatePanel1 gridview1 is clicked, pnlForms and Submit button become visible. 3. When Submit button is clicked, both gridviews should be refreshed, and PnlForms and the Submit button should both become not visible. I believe I may have to put the Submit button in its own UpdatePanel3 but am not sure how to proceed.
In my present code, everything works as desired except Submit button (not presently in any Update panel) is always visible. Assuming Submit button is initialized to not visible, how do I get it to appear when I click the link button in gridview1 and to disappear when it is clicked?
I have a gridview that does a select statement against a sql database. What I want to do is have the data in the gridview refresh upon either hitting the back button or the forward button.
If the back button is pressed it should give me yesterdays data from the table. If I hit the forward button it should give me tomorrows data, at the same time i want the forward button to be limited to going forward only 5 days from todays date. I figure that I have to do this in a Updatepanel however I am unsure as to how to do this.
In my application I am using ajax updatepannel in which there is a tab container tool having 4 tabs, in the third third tab I used ajax accordian control which has 2 panel each pannel have one gridview control a Remove button. Here what I want to give delete facility to the user upon the selection of checkbox corresponding to the particular record. But when I click the button it doesnot triger the button click event of the remove button.

I know everyone has heard this a million times, but I need help with the back button and the AJAX update panel.I essentially have a form, that has 5 fields:Vehicle Make (In update panel #1) Model (In update panel #1) Trim (In update panel #1) Ownership Status Zip Vehicle model gets populated depending on what you put in make, same with trim. Now once the user hits next, I do a response.redirect. When I hit the back button, the possible values, and the current index is wiped for Vehicle Make, Model, Trim. I cannot
figure out a way around this.I have read about that history management feature, but seems uselesss since I need to somehow update the make, model, and trim possible values. Isn't there any way for me to get these values in the viewstate before I post the page?
I have a table which has one row and only one cell will be editable. I have accomplished this with the following code.
$("td#effEndDate").click(function() {
if (!$(this).hasClass("edit")) {
var value = jQuery.trim($(this).html());
$(this).html("<input id="txtEdit" type="text" value="" + value + "" />");

I have the latest toolkit build (3.5) and discovered that a ComboBox button width and height is being set to zero and not displaying correctly after switching tabs, posting back in UpdatePanel, and returning to original tab.
Steps to recreate:
1. Run code and start on tab 1
2. Select tab 2
3. Select a Product to postback
4. Return to tab 1 and notice combo button is gone

I have some code that I am working on that uses an UpdatePanel and some dynamically created buttons to perform functions. The problem is that the dynamically created buttons aren't working the same as my test static button, which is behaving exactly as it should be.
So I was wondering if someone would be willing to simply post an example (in VB.NET or C# please) of the following:
An UpdatePanel has a Label and a Placeholder inside of it
The Placeholder has a dynamic button added to it
Clicking on this button will make the Label say "Hi" without performing a full page postback.
If I can just get that much to work, I am sure that the rest of the code will be fine. I just can't seem to get my dynamic buttons to act like my static ones do in an UpdatePanel.
I have an application that allows users to insert data into a log. The forms are displayed inside update panels and display via modalPopUpExtenders. I am running into a problem where users are able to click the Insert button multiple times before the panel can update that a click was registered.
How can I disable the Insert button once the user clicked on it and had time to communicate with the server? The system is allowing duplicate and triplicates to be inserted into the system.

I have update panel in which i have a label and a textbox and a button
I havwe a Radiobutton list which i am using In the asynchoronous postback trigger of the update panel.
In the Control Id of the trigger I have passed Radiobutton List Id and in the event name I am passing SelectedIndexChanged
But when I click the button no event is firing rest all is working fine.
I have the following scenarion. I have a range of drop down menus where a clietn can select. The code below is wrapped in an update panel but without this, the button click fires a method to retrieve the number of products. So for example, an item is selected from ddlCategory, the btnValidate is clicked and the label returns the number of products within that category.I have the following code for an update panel - I'm just not sure how to implement if effectively.
<asp:UpdatePanel ID="UpdatePanel1" runat="Server">
<ContentTemplate>
<asp:Label ID="lblSearchResultsStatus" runat="server" Text="Number of results found: "></asp:Label>
<asp:Label ID="lblSearchResults1" runat="server" Text=""></asp:Label>
<br />
<br />
<asp:Button ID="btnValidate" runat="server" Text="Validate Search"
OnClick="btnValidate_Click" Width="120px" />
</ContentTemplate>
</asp:UpdatePanel>
How do I go about wiring the update panel so that when a drop down list item is selected, the buttong is effectively clicked?
I am trying to trigger a update planel when a user clicks on an button on a GridView. Once the button is pressed the id of the record gathered and then more information will be gathered and sent to lbl.Text in updatePanel1.
