How to clear AsyncFileUpload if page revisited

Posted By:      Posted Date: September 04, 2010    Points: 0   Category :ASP.Net
Hello all,   just downloaded the latest Ajax toolkit and want to use AsyncFileUpload in my project. But the control keeps the path of previously uploaded file if page revisited again (in my case - a popup page). Is there any parameter can be set to clear the path box (it shows previous path in red). You know, the simple something like syncFileUpload.Clear() would of been nice! But it doesnt have it. Any work around? I tried to place it on page Init and set as New but didnt help.   Thanks in advance.   Nat

Adding table to a page, but the format lost when I use clear border



I added a table to a page, by default, the table layout is the light border. So, I add my content and the vertical align seems to set to the top. But when I changed it to clear border, the content of the table will set vertical align to center. Is there a way to change this back to top align but with the clear border. I don't think I can do this by what is available in the ribbon. Please advice.

AsyncFileUpload - not working w master page in VS2010 B2


I'm using the AsyncFileUpload Extender inVS2010 Beta2. When I include the control in a page derived from a master - even a stripped down basic one does not work. The exact same setup works in a page not derived from a master.  The error I get when I attempt to upload any file is: Unhandled Exception: the attached file is invalid. I have simplified the entire project down to the default created automatically with the AsyncFileUpload control added:

Default.aspx content:

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="UploadTest._Default" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">

Changing the graphics on the home page of a SharePoint site

When you create a site in Microsoft Windows SharePoint Services by using the default Team Site template, the home page includes two default graphics. A Windows SharePoint Services graphic appears in the body of the page, and a picture of a house in a circle appears near the site title. You can change these graphics to customize your site. Changing the smaller graphic requires a Windows SharePoint Services compatible Web page editor

I have 2 web pages. First page has a textbox and a button control.

when I enter test and click on the button , system goes to the second page. And in the second page I want to access the Textbox in the first page. When I try to do this I get the following error.

"Object reference not set to an instance of an object. Following is my code :

Dim txt As New TextBox

' Find the server name on the previous page
txt = CType(Page.PreviousPage.FindControl("TextBox2"), TextBox)

Unique content within master page based on conditions met


 Hi all-

I would like to present users with unique content based on certain conditions being met as they land on the home page (default.aspx).  The condition logic will be in the VB code behind Page Load event. The content will go in a content placeholder as specificed from the master page. 

However, the content change wouldn't be something small (ie making a panel or label visible or not) but rather it will be different HTML,  Divs and databound gridview content.  The HTML content will be stored in the database.

Can someone point me in the right direction for best practices on how to accomplish this?


Launch CMD File From ASPX Page


My organization uses a CMD file to install updated files for a major enterprise application. Currently, we send out an email to users with a link to the file and instructions to run it, BUT inevitably users don't update their machines until their in field and try to start the app.


We're now liking the idea of using an ASPX page to prompt the users to run the updates and to capture the fact that the updates have been run. I realize that we can't capture the success or failure of the update. But we'd like to capture the user accessed the page.


Is it possible to embed into the markup for the page a link to the file on the local intranet that the users can click on to run the file?

The user accessing the page would capture that they did just that. We'd deal with wether or not the update was actually installed or if it failed later with them directly.

Need help redirecting users to personalized page


 Hi, first timer here so be gentle.


I've been able to create a cool little website, it's up and running with users logging in and out, I created roles so my administrative team can see sensitive data that's not available to regular and anonymous users.

Now they would like me to create a page specific to each user.  For instance when user A logs in they are redirected to a page that has information that pertains to user A only (like a list of their benefits/ their remaining vacation time). This page needs to be accessible only to user A. 

I've watched a ton of the videos but have yet to see one that covers this topic, any help would be great!!!

Retrieving a variable from a previous page



I'm looking to have a search page where a user will select an item from a listview, then then taken to another page that wil display data based on their original selection.

A user will type in a string and be presented with a list of usernames that are like that string, when they select a user name who's profile they would like to view I would like the page that they're taken to, to be that users profile.

How would I transfer the variable from the search page to the profile page, and when I work on the profile page, how can I access that variable?


Dynamic page customization in WebForms



I am developing an ASP.NET Webforms application for job advertisements. The application is hosted on my own server and enables registrated users to publish job advertisements with the possibility to submit job applications directly from web. The application essentially consists of two parts: job advertisements and job applications sub-apps. 

The job advertisement application uses RESTful approach, implemented as ASP.NET routing and makes no use of different state variables (like viewstate). I provide custom layout of job advertisement webpage for every client using XML serialization of my internal JobOffer class and using XML ASP.NET control with custom XSLT transformation sheet plus CSS to render the custom design. It is all fine and works perfectly.

The second (job applications) part provides users with a custom webform, which is partically dependent upon the original advertisement (regarding the minimal education level, eligible citizenship or work permissions, licences etc.) and can be tweacked using custom CSS. There is, however, no possibility for custom layout of the elements on this page, which provides a multi-tabbed navigation for different parts of job application. Hence the question 1 (see below).

The application is not ready yet, but I intend to keep it hosted on my own server and provide just some ki
