I have an updatepanel and in my updatepanel I have an button. OnClientClick property that; OnClientClick="return confirm('Can
you delete this data?');return false;"
when I keystroke on enter key, button clientclick is work and there occur warning on my page .
I have a gridview inside UpdatePanel.
Inside gridview there is a dropdownlist and a button on each row. On button click I am opening a panel through Modal popup extneder.
Inside that pop up there is again a dropdownlist. I am adding an item into this dropdownlist based on the selection from the dropdown inside gridview.
like ddl.items.insert(0,'xyz');
But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.
I've a dropdown and a listview inside an updatepanel (Master/Child relationship) so based on value selected in dropdown the listview gets populated. The Listview allow user to perform Edit/Insert/delete of records. I have to implement a scenario when a user is editing/inserting a record and if he tries to navigate away/change the value in dropdown he should be prompted to save the data and if he choose yes in JS Confirm Dialogue then the currently edited/inserting record should be saved (for which i'm trying to mimic the click of the update/insert button using js). I've attached change eventhandler of dropdown using JQuery which is getting called properly bind.
[Code]....
This code gets bind using
Sys.Application.add_load(saveChanges);
I also tried the following
Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(saveChanges);Sys.WebForms.PageRequestManager.getInstance().add_endRequest(saveChanges). The eventhandler gets called correctly but the click() doesn't work! Also the reason I'm calling click() method of button is to perform the validations via RequireValidator/RangeValidators.
I am using UpdatePanel, and I include a gridview inside the updatepanel, I want the grid to be refreshed when button1 or button2 of gridview being pressed. But now when I click the button, the gridview disappeared and look likes the whole aspx is refreshed. I just want to refresh the gridview inside updatepanel. But now the gridview is disappeared. The following is
my source code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Panel ID="Panel4" GroupingText="Enroll student" runat="server" > [code]....
I have an update panel which is inside a Modal Popup Extender. When I click the Refresh Report button it always calls a postback. I need to stop it from posting back.

I've got a rather difficult one here. I have a JavaScript jquery toggle button inside an update panel. Right now i'm using <form body="onload"> to recall this javascript to re-apply the button state after each partial postback. It works, but it requires two clicks sometimes.
The problem is... after a few clicks, it is significantly slowing down the PC, and I can see the clicks trailing half a second to nearly a second. If I have a group of buttons, all those click events are just catching up to my clicks. It is rather amusing but I suppose it has to do with the fact that the postback is calling the <body onload=" event> each time after the button is clicked.
so how can I then, make this performance faster?
I'm currently building a simple chat application and I have everything working real smooth except for one thing, and this problem is only in IE as far as I know (in firefox there is no problem).
In my chat application I have the textbox where the user writes the messages to the chat and the button that sends this message togheter in an updatepanel (so that there is no visible postback when pressing the button). I also have in the form tag "defaultbutton=" set to the button. The problem is that when the user uses Internet explorer and presses Enter instead of pressing the button with the mouse that after the 2 first times he/she does this causes the textbox to stop focus on it, which it shouldnt do as in the end of the button the code says it should focus, which works the 2 first times for some reason.heres the code where the problem exists:
aspx:
form id="form1" runat="server" defaultbutton="Button1">
<asp:ScriptManager ID="scriptManager" runat="server">
</asp:ScriptManager> [code].....
I have a button that is inside of an updatepanel, I want it so that whenever the user clicks on the button it would update items in the updatepanel and after that it would activate the animationextender but I can't do that as of now because on the button I have OnClientClick="return false;".
View 3 RepliesImageButton inside Datalist inside update panel is not firing in my asp.net web page. what should i proceed??
View 1 Repliesi am using vs2008. 1/ i am placed a datagrid control, a textbox and a server side button are inside the CollapsiblePanelExtender.
2/ The collapsible panel Extender placed inside the updatepanel.
3/ outside of updatepanel i have another button("next page") to redirect to next page.
When the page is loading, i am displaying all the records in datagrid. For an example 100 rocords. if i entered some values in textbox and click the button it fetches searching result based on inputs and displaying it in datagrid (for example searched result 20).
Now, I click the button "next page" it redirect to next page. if the user click the browser back button, i need to keep the datagrid to show only searched result. but Instead of that, it displaying all the records(100 records). how to resolve this?
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].....

Buttons inside UpdatePanels are automatically registered as triggers for that UpdatePanel. Is there a way to make the UpdatePanel ignore one of it's inside buttons? That is, to make it so that clicking this button does NOT trigger any sort of postback?
View 2 RepliesI am using a MultiView inside an UpdatePanel with several views within it and a button on each that is supposed to validate the controls on the current view before moving onto the next view in the sequence (a bit like the Wizard control except I wanted more freedom).
I am using an LinkButton but the problem is that the LinkButton is not causing validation -- I have also tested with an ImageButton which isn't causing validation either. However, when I use a normal Button, the validation does work. I have grouped my validation controls into a ValidationGroup and made sure that CausesValidation is turned on.

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:

I am using an updatepanel, with a bunch of dropdowns that have an onchange for Javascript, that use ajax (partial page postback). The problem is: I have two dropdowns at the top (also inside the updatepanel) that let me change the current month or year. Sometimes...they change the page (response.redirect), and sometimes they throw that error above. Also, they are the Only two buttons on the page that aren't doing an "onchange" and then ajax stuff....they are actually posting back the entire page to the server (or trying to).
