C# - How To Use AutoPostBack Inside UpdatePanel

Sep 24, 2010

I have two DropDownLists inside an UpdatePanel.

The values shown inside the second are dependent of the selectedValue on the first, so, I need AutoPostBack=true.

But, whenever the selected value in the first DropDownList is changed causes the UpdatePanel reload.

How can this be solved?

PS.: The UpdatePanel's UpdateMode property is set to Conditional.

AJAX :: TextBox AutoPostBack Inside UpdatePanel?

Jul 29, 2010

I have two textboxes insie an updatepanel, the same update panel also has a trigger from a Clear Button from the other update panel. The first Textbox AutoPostBack is set to true. The first time when the textchanged event is fired, everything work as expected--the labels got populated, the focus is set to the second textbox. However after I click on the Clear button, i entered something to the first Textbox, its TextChangedEvent fires--the labels got populate, the focus seems set correctly to the 2nd textbox, but I
cannot enter anything to the second TextBox. it seems like the form is not active--when i hit tab, I expect the focus move to next control, instead it moves to the URL box. Turn off the AutoPostback then put a button next to the first textbox will fix the problem, but I am wondering if there is other workaround to keep the AutoPostback of the 1st textbox?

I am using IE8, here is a simple test page:

How To Avoid UpdatePanel Scrolling On AutoPostBack

Mar 1, 2011

I have an ASP.NET FormView within an updatepanel. I'm auto-saving the form by setting AutoPostBack=true for each of the items within the FormView.

This means the user can click a few elements in quick succession and fire off a few async postbacks almost simultaneously.

The issue I have is that the user is able to keep scrolling down the form while the async postbacks are not yet complete. The browser always scrolls back to the position it was in at the first postback.

Page.MaintainScrollPositionOnPostback is set to False.

I've tried all sorts of things in ajax and jquery with:

AJAX :: AutoPostback In Repeater In UpdatePanel Is Refreshing The Page?

Aug 31, 2010

I've got a TextBox with AutoPostBack="true" and OnTextChanged property set.

The textbox is located inside a Repeater, which in turn is located inside an UpdatePanel.

Problem is - whenever the TextBox postsback, the whole page gets reloaded, instead of the UpdatePanel only.

Here's how the thing looks:

[Code]....

Interesting thing is, if I take the TextBox out of the repeater, it refreshes only the UpdatePanel. So is if I put a Button inside the repeater - only the UpdatePanel gets refreshed. But whenver I place an AutoPostBack-ing control inside the Repeater, the whole page gets refreshed.

Web Forms :: Hooking Dynamic Controls Inside An Updatepanel As An Asynctrigger To Another UpdatePanel?

Oct 7, 2010

I have two update panels and one javascript control.

When the javascript button is clicked, it forces a partial postback on UpdatePanel2. UpdatePanel2 is populated with dynamically created buttons that have javascript effects (jquery) but when click can also induce a postback. My problem is that, when clicking on these dynamic buttons, the whole page does not do a partial post back but rather UpdatePanel2 itself does a partial postback and everything is gone.

However, what I want to do is be able to tie each of the dynamic buttons in UpdatePanel2 (After being dynamically created) and make them an asychnonous triggers to UpdatePanel1. So that when clicking on these dynamic buttons, ONLY UpdatePanel1 is doing a partial postback refresh. UpdatePanel2 stays put and remains the same.

AJAX :: Editing Image Inside DetailsView Inside UpdatePanel?

Oct 4, 2010

I'm trying to add and edit an image which is located in a detailsview which is inside an UpdatePanel. After I read relevant topics in the forum I installed the Ajax Control Toolkit. Below is my source code. When I used it only for insert new image it worked great. The problem caused when I tried to implement it on the Edit mode, i.e. when I tried to edit the image and upload a different image. Unfortunately it didn't work as I hoped. Nothing happend and the image hasn't been changed. I also tried to change the IDs (AsyncFileUpload ID) to be the same in both places but it didn't work either.

The source code:

<asp:DetailsView ID="dvMovie" runat="server" Height="50px" Width="695px"
AutoGenerateRows="False" DataSourceID="sdsMovieById"
BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" [code].....

Forms Data Controls :: Disable Autopostback Of Checkbox Inside Of GridView During SelectedIndexChanged Of ListView

Sep 8, 2010

I have a checkbox placed inside a gridview:

<GridView><asp:TemplateField HeaderText="Driver"> <ItemTemplate> <asp:CheckBox ID="CheckBoxDriver" AutoPostBack="true" OnCheckedChanged="GridView_Persons_SelectedIndexChanged" ValidationGroup='<%# Eval("ID") + "-" +((GridViewRow)Container).RowIndex %>' CssClass="CXDriver" runat="server" Checked='false' /> </ItemTemplate> </GridView>

For example: A listViewItem 1 has 3 drivers are checked, A listViewItem 2 has 2 drivers are checked.

Therefore, if changing the selectedIndex of the list, the checkbox indexChanged event will be fired.

How could I disable the autopostback of the checkbox during the listview item changed.

Using JS Event Handlers Inside A Wizard Inside An Updatepanel?

Feb 28, 2010

I've got a textbox being used to enter a password inside a wizard control. I'm trying to get a password strength meter working with it.

Unfortunately, the password box isn't visible until step 4 and this means that I can't register the event handler onload() and putting some JS next to the PW box to register the event handler doesn't seem to fire. I'm guessing this is due to the contents of the wizard being loaded through an AJAX postback.

C# - PopupControlExtender Inside UpdatePanel?

Jun 15, 2010

So i use PopupControlExtender (to edit some of the fields) inside ListViewControl which itself is embeded inside an UpdatePanel.

The problem is as follows whenever you cause partail postback the popup panels are created client side outside the updatepanel. And you get more clientside controls with the same clientside ID. When you postback with popup panel the server side control eg. Texbox has Text = clientsidecontrol1.text, clientsidecontrol2.text, clientsidecontrol.text3

Is there a way to prevent this.

Asp.net - ScriptControl Inside UpdatePanel

Oct 21, 2010

I have a ScriptControl (requires ScriptManager) with JavaScript to handle client-side interactions and ICallbackEventHandler to communicate back and forth. Everything works perfectly with one or multiple instances of the control on a page. I placed the control inside a GridView with sorting and it still works. However, I place the GridView in an UpdatePanel and now whenever I sort I get the following error for each instance:

Sys.InvalidOperationException: Two components with the same id 'GridView_ctl02_MyControl' can't be added to the application.

Can someone point me in the right direction on how to solve this? I am assuming ScriptManager is not disposing of the old Sys.UI.Control objects before trying to $create() the new ones with the same ID. I thought the UpdatePanel/ScriptManager combination would automatically take care of disposing objects that would be replaced?

Placeholder Inside An UpdatePanel?

Nov 10, 2010

A little pseudo code to provide some background:I have an ASPX with a placeholder and a buttonWhen the button is clicked it adds a web user control (uc1) to my placeholderhe uc has a buttonWhen clicked it adds a different user controls (uc2) to the placeholderStepping through the code, if I look at the placeholder.controls.count before and after the button-click in #4 the count increases by one, as you would expect.The problem is that the uc2 added in #4 doesn't appear on the screen. So, I wrapped my placeholder in an UpdatePanel. I've never used one before. So, I could refresh the placeholder after the uc2 was added.relevant ASPX code

C# - UpdatePanel Inside Repeater?

Mar 28, 2011

In my UserControl, Im trying to update a updatepanel that is inside a repeater like this:

HTML-Markup

<asp:UpdatePanel ID="updDocumentQuickView" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Repeater ID="repFolders" runat="server"

[code]...

The end result I get is that updDocumentQuickView is the UpdatePanel that gets updated, and not updFiles. If i wrap an UpdatePanel around lnkFolder, then that UpdatePanel gets updated, with the same C# code. Ive checked what kind of data that are sent back with fiddler, and the wrong UpdatePanel is sent. Im getting the correct RepeaterItem, and both repFiles and updFiles are found. What do I miss to get the right UpdatePanel to get updated?

UPDATE

Hawxby solution solved the problem with updDocumentQuickView getting updated, thanks for that. But im still having problems with updFiles sending nothing back. Some further testing, with putting literals inside updFiles and working, tells me that theres something with repFiles that isnt returned. repFiles does have data that is bounded.

FINAL SOLUTION

repFiles.Visible were set to false in repFolders_OnItemDataBound, no wonder it didnt show.

AJAX :: ModalPopupExtender Inside UpdatePanel?

Apr 15, 2010

I have a menu of buttons inside an UpdatePanel (UPD_Menu) so that buttons can be enabled/disabled without refreshing the entire page. When a user signs in, the Sign Up button is disabled and the Profile button is enabled. Likewise, when the user signs out, the Sign Up button is enabled and the Profile button is disabled.

Inside this UpdatePanel (UPD_Menu), along with the buttons, is a ModalPopupExtender that is fired by the Sign Up button (TargetControlId="BTN_MenuSignUp") that pops up a dialog Panel (PNL_SignupProfile) that contains yet another UpdatePanel (UPD_SignupProfile) that contains a Submit button as well as a Cancel button (CancelControlId="BTN_SelectCancel").

The behavior I am getting is when the user clicks no other button than the Sign Up button, the dialog (PNL_SignupProfile) pops up and is modal. The Submit button closes the dialog and makes the once-hidden panel appear under the menu of buttons. This is not good as only the inner UpdatePanel (UPD_SignupProfile) should be updated without affecting the outer UpdatePanel (UPD_Menu). The Cancel button works as it should by simply closing/hiding the dialog.

If a user clicks any other button in the menu first, nothing happens ( no codebehind yet) but when the dialog (PNL_SignupProfile) is shown, the Cancel button causes the hidden Panel (PNL_SignupProfile) to appear under the buttons. I've tried many different things to no avail...including putting the dialog panel in different places and even controlling the ModalPopupExtender from code.


The only code I have so far is for handling the signin/signout and enabling/disabling the signup and profile buttons based on user signin. There is no code yet to handle the menu of buttons nor the submit button of the popup dialog.

Here is the code:
