what is the uses f Triggers in UpdatePanel control
View 3 RepliesI cannot determine why this is happening, but I have narrowed it down to the javascript in one of the controls in an updatepanel.
ASP.NET 2.0 aspx structure:
A formview contains a large updatepanel. The updatepanel contains all the controls on the page. Only three controls are autopostback=true: two dropdowns and a checkbox.
The last three controls in the updatepanel are textboxes. Their autopostback=false. Each textbox has an anchor whose javascript launches a pop-up calendar window. The pop-up calendar selection populates the corresponding textbox. No problems there.
The bug happens whenever I fill in all three dates at once (I launch the calendar three times and select a date each time), and then I click Save. The form's save action fails because the code can no longer get to the controls in the formview. The formview.controls.count is zero.
It works if I fill in any two of the three dates *or* I fill in all three dates by typing the values into the textboxes (bypassing the pop-up calendar). I can fill them in random order, and any one or two are fine, but all three at once triggers the error.

I have a linkbutton "One more", which have to create a new FileUpload control when user clicks it.

how should I make an ability to upload non-defined number of photos?
On my MasterPage I use UpdatePanel to update whole ContentPlaceHolder. Example of code you can find below. All content pages work fine with this MasterPage except one. This page is very complex. I noticed that when I disable UpdatePanel in my MasterPage this problematic page works fine. Question: is it possible to exclude something from UpdatePanel - in my example whole page but only this one?
<asp:UpdatePanel
ID="UpdatePanel2"
runat="server">
<ContentTemplate>
<asp:ContentPlaceHolder
id="MainContent"

My popup panel is disappearing everytime the timer ticks in an updatepanel.How can i solve this problem please friends.
View 5 RepliesThis sounds weird, but I would like to NOT update a control that's within an update panel. Is this possible? basically the way facebook works, facebook controls are rendered on a "get" command. but I have controls within the same update panel that cause AJAX postbacks. When the postback's happen, I lose my facebook server-side controls. I am wondering if I can "unregister" a control from an update panel? Or do I just have to redesign that page.
View 3 RepliesI have a custom control created to autofill the box as typed in. Its working great. But if I put the control inside an Update Panel, it works for the full postback but if partial postback happens (because of the update panel), it does not work.
View 7 RepliesI started a new project using VS2010. I have a menu control connected with an XML datasource inside UpdatePanel, Menu control works fine, problem is the styling. using a StaticHoverStyle Css works only after the page reloads, when I click a menu entry, the entry is selected but StaticHoverStyle does not reflects the menu items anymore (of course when I hover the items) Same behave with both Net versions 3.5 and 4. When I remove the UpdatePanel the StaticHoverStyle comes back to life ( post back occurs ).
View 1 RepliesI should probably say I love these forums, I've been viewing for some time and have found loads of valuable information. I'm having a problem with my project, I have an updatepanel containing several items (Two Daypilot Schedulers and a Literal Control). I have set it to conditional and have it update whenever bookings are added/modified in the schedulers. This all works perfectly! I then have a literal control which contains div items with onmouseover= parameters. The control basically contains a list of pending booking requests. On Page_Load I call a method which populates the list...which works fine.
However, whenever I call the UpdatePanel.Update() method (say, when a booking is added), the schedulers update but the literal control does not. I have gone through the debugger and found that the LiteralControl.Text property is correctly set to the new updated list just before calling the Update() method. So basically it all works perfectly apart from the literal control not updating along with the schedulers in the UpdatePanel.
I'm new in developing and i'm in trouble with update a UpdatePanel inside a User Control from a Repeater inside another User Control.
View 3 RepliesI want to change the visibility of two asp.net image controls (runat="server") at the beginning and the end of the method call duration. I mean, I want the first image displayed and second one remains hidden until the last line of my method, which in turn, the second image becomes visible and the first one hides. I've put the area of the triggering control in updatepanel and have declared triggers of the updatepanel; But when I press the control (which is a button), the image at the end of the process is displayed correctly and on time but the one which should be displayed in the first line of the method is not displayed. I've configured my updatepanel to use conditional update mode and have used these lines for my intention:
imgLoading.Visible = true;
..
rest of the process
..
if (true)
{
imgLoading.Visible = false;
imgSuccess.Visible = true;
}
I am using a modal popup control which contains an UpdatePanel. There are one combo and few text boxes and Calendar control in it. When I select any item in combobox, then it's selection change event is fired and there iI set the values of other controls and finally I call update method of update panel. Functionality wise it works properly but it takes a time to update the panel.Here combobox contains around five thousands of items. But when it contains 100s of items it works good.

I develop an ASP.NET web application. The server side receives a stream of image data (JPEG frames as byte arrays).
It should processes them and send the images to the client side periodically.
For displaying these images on the client side I tried to use an approach similar to this described in the post "Improve your Image(s)" (http://steveorr.net/articles ImproveYourImages.aspx) by using an auxiliary ASP.NET page for the purposes of the server side image processing.
When I used a client side button to request the image ocntrol (imgCameraCapture) update with its URL pointing to the processing page (GenImage.aspx, as in the above post), everything worked fine (with exception of the whole page re-rendering on each button event). The image was updated.
For a periodic update of the client image control on the main page I put in an ASP.NET AJAX UpdatePanel andset it to update conditionally by triggering to an ASP.Net AJAX timer (10 seconds) event in order to achieve a partial page update (just the image).
II used the timer tick event handler to update the image by invoking the separate ASP.NET image data processing page there as in the button click event handler. But in the timer tick event handler the processing page was not invoked and the image was not updated.
This is the C# code behind executed in the button clik and timer tick event handlers:
imgCameraCapture.ImageUrl = "~/GenImage.aspx";

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
