AJAX :: Postback Method Updates Entire Page

Feb 19, 2010

I don't know why, but even using update panel, my postback method updates the entire page. I'm using a master page with aspScriptManager inside.
My ASP.Net code:
<div> <asp:UpdatePanel ID="updProva" runat="server">
<ContentTemplate> <asp:Panel ID="pnlProva" runat="server">
</asp:Panel> </ContentTemplate> </asp:UpdatePanel> </div>

The CodeBehind (C#) creating some RadioButtonList controls in my ASP.Net page, I'll post the main function and de Page_Load:
createTest function
[Code]....
Finally, the Page_Load:
[Code]....

VS 2008 Is There A Way To Force A 'postback' On The Entire Page

May 12, 2010

I'm having a problem with entering edit mode in Gridview. When I click edit, it shows it in normal mode (labels) even though RowCommand does successfully fire.

But I have to click it AGAIN to get it to show the TextBoxes of 'Edit' mode.

How can I fix this? Is there a way to force a 'postback' on the entire page, or re-render a control? (i'm assuming thats the problem)

Here's the pseudo code:

GridView1_RowCommand(....)
If e.CommandArgument = "EDIT" then
GridView1.EditIndex = 5
End IF
End Function

A click of the 'edit' button returns the gridview with the normal labels. Then when I click it again, the TextBoxes show up.

Web Forms :: Find The HTML Of Entire Page Causing The PostBack ?

Jul 30, 2010

I need to know if there is any server-side function/custom-code available to find out the HTML of the entire page which is causing the PostBack.

I don't want to do it using JavaScript/jQuery but instead do it at server side.

A JavaScript workaround that implements it can be found at this link. [URL]

Reason, Why I need it? I am writing some inline javascript in page which performs some vital actions and supposed not to be tampered by user(hacker). So, when a postback occurs, I would like to find out the HTML of entire page (at server) so that I can verify it (I have already generated the hash code for entire HTML while rendering the page to check it on consecutive postbacks) for non-tamering and then process further.

This is the reason why I need a way to find out the HTML of the page causing the PostBack.

Web Forms :: Master Page To An Entire Website As A Method Of Implementing Site Security Consider?

Feb 21, 2010

I have a site with about 4 pages or so. I was asked to implement a very simple security (check if user in database, if not kick out) using active directory and validating against a table of users. I was simply thinking of createing a master page and making all pages inherit that master page. I would then authenticate the users from the master page.

AJAX :: Updates On User Control Not Available On Housing Page

Jun 27, 2010

I have a user control that I am explicitely calling from an aspx page. In page_load of hte aspx page I have the following, myControl = (DynamicTable)Page.LoadControl("../inc/DynamicTable.ascx"); Then in my code where I want it to execute the control, I have this pnlESDDEnrolled.Controls.Add(myControl); where pnlESDDEnrolled is the panel I am loading it into for display. So, I execute the aspx page, it links off to the user control, populates the control, returns back to the aspx page and the page dispalys with the user control in the middle of it. All is well.

The problem comes in when updates are made on the user control. Keep in mind, that other data is updated on the page as well, and the update button resides on the page, not the control. Anyway, when the update button is pushed, the button_click event is fired on the page, but the updates that I made on the user control are lost. Since the page loaded the user control and then the usercontrol executed the page unload method, the page has no knowledge of the user control anymore. Thus, when the update button on the page is pushed, I guess I am not really sure what happens with the updated data on the user control. All's I know, it is lost.

AJAX :: Force TabPanel To Fill Entire Height Of Page?

Feb 2, 2010

How do I go about forcing a TabPanel to fill the entire height of the page? Each of the tabs in the tab control are being populated with different data such that each panel is of a different height. Some of the tabs may only fill half of the page while others may exceed it, which is why I can't simply hardcode the height. I've tried wrapping the <contenttemplate></contenttemplate> inside of a div and set the div height to 100%, but that obviously did nothing.

AJAX :: Animated Gif And Entire Page Freezes During UpdatePanel Post Back?

Dec 16, 2010

I have been searching the net and found no clean cut answer to my problem. I have an animated spinning gif, that is displayed within an 'UpdateProgress'. This gif is to be displayed when the page is posting back to the server and processing.

The animation will start to spin but basically stright away it stops. I have noticed that the file menu within IE is also frozen at this point, up untill the page fully refreshes. I have tested in firefox and safari and am recieving the same problems.

developing in visual studio 2010, framework 4.0, IE 7,8.

AJAX :: Stopping Web Method From Firing On Postback?

Jul 27, 2010

I'm inplementing the Cascadingdropdown control from the toolkit. That's all working fine. The user makes their selection from the dropdown and submits the page to return search results to a listview control.

However, I've noticed that all the dropdowns re-populate themselves when the page is posted back. There is no need to reload the controls on a postback, how can I stop that please as it's very annoying?

AJAX :: Every Single Action Caused The Entire Page To Reload When Accessed It From A Remote Location?

Nov 30, 2010

I know practically nothing about AJAX, but fully intended to utilize it in the future. Right now though I am noticing a behavior that may require that I implement it sooner then I planned.

I have been working on a fairily sophesticated web form that is made up of tables, dropdown lists, map buttons, and labels. As various controls are selected, specific tables are enabled or dropdowns/labels populated with information. All of this is working great, but when I put it all on a server and accessed it from a remote location, I noticed that every single action caused the entire page to reload.

From what I have read, it looks like AJAX and the UpdatePanel control will allow me to only refresh those areas that should be refreshed. Before I look further into implementing this, is this the only way to go? From what I have read on some other blogs, the UpdatePanel has some high performance costs.

AJAX :: 401 Unauthorized Error In App, AJAX Control Calling Web Method Within Same Page

Jan 10, 2010

I'm using a custom AJAX based validation control to check user name availability from database.

remote server returned an error 401 unauthorized

C# - Can Quickly Run Entire Page's Text Through A Function On Page Load

May 14, 2010

i have setup a profanity filter with bad words in a XML file and have the following function to run on my page to replace the words:

BadWordFilter.Instance.GetCleanString(TextBox1.Text);

i'm about to go through my entire site now wrapping that function around every little text variable one by one and it's going to be a huge pain in the butt

i'm hoping there's a way that i could just set my masterpage to automatically run all text through this thing on any page_load, so that the effect would be site-wide instantly. is this possible?

AJAX :: Mozilla Does A Full Page Postback And Refreshes The Whole Page

Im implementing a simple form with ajax to warn the user if email has been used or not for registration, and it looks to be working fine with IE but mozilla does a full page postback and refreshes the whole page.

I already tried changing to updatemode to conditional, all the triggers are set as async, etc but mozilla keeps doing the same, Im sure it is a known problem I may not be the first one facing this problem so i guess there is a simple workaround for this.

Ajax - Implement Real Time Updates?

Feb 27, 2010

I have seen several websites that show you a real time update of what's going on in the database. An example could be. A stock ticker website that shows stock prices in real time Showing data like "What other users are searching for currently.." I'd assume this would involve some kind of polling mechanism that queries the database every few seconds and renders it on a web page. But the thought scares me when I think about it from the performance standpoint.

In an application I am working on, I need to display the real time status of an operation that a user has submitted. Users wait for the process to be completed. As and when an operation is completed, the status is updated by another process (could be a windows service). Should I query the database every second to get the updated status?

Web Forms :: Partial Page Updates

Mar 18, 2011

I have a serveral ASP.Net webpages with multiple functions that I am optimizing. Each function is being moved into a usercontrol that will be called by an AJAX function to replace that part of the page. The function (see below) works for some controls,
but not others. The error message returned is "Error executing child request for handler 'System.Web.UI.Page'."

To isolate the problem, I created a new user control with nothing but a textbox on it and it failed. Same thing for many of the others controls. However, put nothing but a Label, repeater, or pic onto the control, and it works.Is this the correct way to do partial updates back to the page? Or should I be using a different approach?

[Code]....
