AJAX :: Use A Fileupload Control Inside An Update Panel

Apr 5, 2010

Having a bit of trouble here. I know that if you want to use a fileupload control inside an AJAX update panel then you need to create a trigger for the control that performs the uploading postback to the updatepanel, but the problem is, I have an update panel that contains web usercontrols. I therefore can't add a trigger to the control(FileUpload) directly because it exists in the web control.

Fileupload Within Update Panel / Can't Get The FileUpload Working Properly

Jan 15, 2010

Hopefully someone can give me some pointers to get this working properly.

I have a webpage which I would like the ability to upload files to be stored in a database. Here's the layout of the page:

[code]....

The update panel is configured as such:

ChildrenAsTriggers="True" EnableViewState="True" RenderMode="Block" UpdateMode="Always" Visible="True" Runat="Server"

The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.

Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.

Nov 22, 2013

I have a page on which there is a textbox that is in update panel and has text changed event and autopostback=true. On the same page there is a 'Retrieve' button(inside repeater control) outside the updatepanel. Now what is happening is if user inputs data in the textbox and clicks retreive button page_load event is firing twice which is not what should be happening, one time its the partial postback due to the text changed event and second time is the page post back. I would like to restrict the second postback.

AJAX :: Update Panel Doing Full Postback?

Oct 20, 2010

I am having an issue with an update panel, which is still causing the entire page to postback.

I have made sure i have all the correct bits in the web.config, section groups, httphandlers, httpmodules, additonal assemly etc... but it still does not work. I have got it to work in a way,which is why i think i have the config right, because if i take the search panel of and place it outwith the update panel, the go button only postsback the rest of the page not what is inside the updatepanel.

I am using a master page, but the update panel only appears in the content page, within the content tags.

Javascript - Usercontrol Disappears When Using Update Panel?

Mar 3, 2011

I have a user control which acts as a footer for my website and uses java script jqdock.js to show apple type bottom menu. I added an update panel to the usercontrol. What problem I am having now is, it works fine initally but once I click the mail button which is in the usercontrol , the whole user control dissapears, after postback i guess. below is the usercontrol and code view:

enter code here


public void Page_Load(object sender, EventArgs e)
{

// Page.ClientScript.RegisterClientScriptInclude("bottomMenu", "../js/jqDock.js");
ScriptManager.RegisterClientScriptInclude(this,this.GetType(),"bottomMenu", "../js/jqDock.js");[code]....

AJAX :: Refreshing Update Panel Through Javascript Postback?

Mar 17, 2010

In one of my webpage, I have a parent window where i have a datalist with 10 rows of images. when i click any image a pop up window(child window) opens.

The child window has a form to be filled by user. Once user fills this form, he will press the save button. Once the save button is clicked, the child window should be closed and the datalist(in the update panel) in the parent window should be refreshed.

This is how I am trying to achieve this. On click of the save button a javascript function is being called of the parent window like this: window.opener.refreshDataList();

in the refreshDataList() function I have written the following code:

{
childWindow.close();
__doPostBack('ctl00_ContentPlaceHolder1_UpdatePanel1', '');
}

This works like a charm in Internet Explorer. However in Mozilla and Chrome it doesnt work. While testing this I added an alert statement ind the refreshDataList() function like this..

{
childWindow.close();
alert("Testing");
__doPostBack('ctl00_ContentPlaceHolder1_UpdatePanel1', '');
}

Once I added the alert statement, It started working in both mozilla and chrome.

So I realize that It could be an issue related to focus. I have done window.focus()

but still its not recieving any focus and not working in Mozilla and Chrome.

AJAX :: Update Panel Causing Complete Postback?

Jan 1, 2010

Below is the sample code on using the update panel. The page just has a button and a label. On button click it updates the label with the server time. Though the label is inside the update panel the page goes for a complete postback. in understanding why it is behaving like that. I tried the options of Updatemode, using different script references nothing seems working for this simple application.

-- aspx page
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
