AJAX :: Postback Does Not Reset Meta Refresh Tag?
Feb 25, 2010
I have a kiosk application that uses master pages. There is a refresh meta-tag on the master page (or I can add it programmatically using Page.Header.Controls.add(metaTag), it makes no difference for my problem). When the user does not interact with the aplication it should return to the default page. But when the user does react using async postbacks only a partial postback is performed which does not reset the html meta refresh header, so it just keeps on ticking and after x seconds the page redirects to the default page. How can I avoid this from happening. The meta-tag can not be in the updatepanel so even though I can manipulate it from the code-behind when the async postback happens, any changes I make (for example sometimes when the user makes a mistake he should be redirected to a clean version of the page he is currently on after showing a modal message, so I have to change the url of the meta-tag content to no longer use the default page, but the current page) are not implemented.So the main question is, how can I manipulate (or reset in case of refresh meta tag) meta-tags in an async postback ?

I have a masked edit extender extending a text box. I enter the date 01/01/0001 then change a selection on a drop down list inside the same update panel with the autopostback property set to true. The date is changed to 01/01/1910.

When I render a page in ASP.NET, the following happens
[Code]....
My masterpage looks like this:
[Code]....
So what I'm asking is, where the heck has this refresh meta tag come from, why has it put it between my head tag and body tag, and why has my page title jumped outside of the head?!
When viewing the page's generated source in firebug, it shows the title tag and this new meta tag within the head tag, but viewing the source in any browser, it looks like the above. When using wget to scrape the page, it also comes out incorrectly as displayed above.
why browsers may be interpreting this in different ways, and more importantly where this new meta tag has come from?

I have a number of cascading dropdownlist controls on a page. The results in dropdownlist2 are dependent on the results in dropdownlist1, pretty basic stuff.
I now would like to eliminate the terrible postback or refresh of the page that occurs after the SelectedIndexChanged event fires on dropdownlist1, is it possible to do that in Ajax?
What I want the results in dropdownlist2 to populate without the obvious refresh of the page.

I have a slideshow extender, I will change the slideshow extender's contextkey value by a button click event. So that after button click the slideshow will display different set of image. Originally with postback everything work fine, but I don't want the whole page to refresh.
So I put the slideshow extender inside an updatepanel with triggers target the button click event. Now the whole page didn't refresh and the slideshow extender's contextkey value did change (same code as before) after button click event. However the image set on the slideshow didn't change.
I think I am missing some sort of slideshow extender reload or refresh call but I am not sure how to do this? I didn't see any related property with slideshow extender...

I have an update panel with content that needs to be updated by a listview item which is a linkbutton, in .NET 3.5 I just used the defaults on all the controls and everything worked fine, after the upgrade to 4.0 the linkbutton causes a full postback with page refresh. I did try setting the linkbutton's id as the trigger for the update panel and still causes same page refresh. The scriptmanager is on the masterpage with enablepartialrendering = true.

This upload is working. But why the page is getting refreshed? this is not partial post back and instead it 's full post back. i have read the articles for the fileuplaod with issue inside the update panel. is there any way to achieve this asynchronous upload on button click?
I don't want to use the Ajaxtoolkit Asyncupload because that will upload (Ref : [URL] ....] the moment when we seelct the file itself which i don't want to do that. i need to do on the button click event.

I have a web form with some labels, textboxes, buttons and a gridview. The gridview has AllowPaging ="true". Girdview displays record numbers (hyperlinked), When I click on a record number in the grid view it populates textbox1. Then I hit the 'Search button to auto populate the form the that record data from the database.
My problem is when I am on say 5th page on my grid view and click a record number to go in textbox1, and then click on the search button to auto populate the form, the gridview goes back to page 1.
How do I make the search button not reset/refresh the gridview?

[URL] .... am using this functionality in my project and it is working very fine but i am facing very strange issue while using this.
The above functionality is not working when we place dropdownlist and textbox inside updatePanel and ModalPopupExtender
The .aspx page where i am using ModalpopupExtender and UpdatePanel for DropDownList and Textbox is below
<%-- *************************** MODAL POPUP EXTENDER ***************************************************** --%>
<asp:HiddenField ID="HiddenField3" runat="server" />
<asp:HiddenField ID="HiddenField4" runat="server" />
<cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="Div6" TargetControlID="HiddenField3"
BackgroundCssClass="modalBackground" CancelControlID="bclosemodalpopup" >
</cc1:ModalPopupExtender>
[Code] ....
The above code is not working with UpdatePanel but it is working if we remove DropdownList and Textbox from updatepanel.
The javascript code which i am using is below
<script type = "text/javascript">
var ddlText, ddlValue, ddl, lblMesg;
function CacheItems() {
ddlText = new Array();
[Code] .....

I have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.
Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)

Anyone with similar conclusion? GridView does not databind/refresh upon postback unless the postback is called by itself?

I have an application where the user scrolls down through a grid and clicks a SELECT button to populate some textboxes based on the content of the grid. On the return from the postback the selected row is out of sight because the grid comes back reset to the top within the scroll window.
Is it possible to have the postback return with the highlighted selected row visible rather than forcing the user to scroll back down to find the selection?

I have a panel that users are filling blanks in it.
In this process, several post back will be fired and controls like labels, dropdownlists will change their values, nested panels will change their visible.
Now I wish to know how I can reset these changes when user submit the form.
Like
protected void btnSubmit_Click(object sender, EventArgs e)
{
Panel1.Controls.Reset();
//there is no such a method of Panel
}
As a clarification, I still need to use some of the value in the btnSubmit_Click and display some submit info based on these values. So I *cannot* use Response.Redirect().

I have written a simple jQuery dialog box that will appear in an asp panel if the logged in user has not reset their password in the last 90 days. This is working great, however when the user types in their password and presses submit to insert the new password into the database, the parent page is posting back before the click event is fired on the user control.
Here is how it is set up:
default.aspx
<asp:Panel ID="pnlTest" runat="server" Visible="false">
<div id="dialog" title="Password must be reset">
<cms:ResetPassword runat="server" ID="reset" />
[Code]....
Whenever I click the button to change the password, the default page is calling a postback and it is blanking out the text that was input to change the password, so when the click function gets called the strings come through as "" and it throws an error.

I have a couple of fields on a form that will be populated with default values. I would like to put a button that will allow me to reset those fields to their default values if they have been modified. However I would like to avoid the postback so that I don't have data being sent to the database. Is it possible to add a javascript hook such that when that button is pressed I can pull the default values and populate those fields in javascript?

There is a asp:Label in the page for showing message from server.
The message can be sent by server at any time.
I added a handler to update the Label's Text, like following:
void MessageReceived(object senders, EventArgsMessageReceived e)
{
lblMessage.Text = e.Message;
lblMessage.DataBind(); //To show the message
}
I am sure the break point of 'lblMessage.Text = e.Message;'' is hitted.
But the DataBind() seems not work, and the label isn't updated.
