I would like to download a webpage from tumblr, so I can scrub it from the images -
https://www.tumblr.com/tagged/otto_schmidt
However (once your logged in), the page continues to load images, as you scroll down further.
What's the best way to download the page in C# so you can scrub it?
You can you winform webbrowser control, fire document loading complete event.
Hope this help!

I want to show a webpage without loading anything but the page itself. Not even CSS or JavaScript pages. I want the WebView to make only one web request - to get the page from the url I provide it. Nothing else.
Is there a way to achieve that?
I am maintaining a website written in C# with ASP.NET. At the bottom of a page is an iframe. When a user clicks a button, the source for that iframe is set with Javascript to a page on the server.
showLoadWidget();
document.getElementById("downloadFrame").src='SdrTrendDownload.aspx';
return false;
That page generates a file and allows the user to download it. Once the download file box pops up, I want to call hideLoadWidget() so the 'Loading Data...' overlay goes away. How do I detect when the download file box pops up?
You can't detect that in addition this get more complicated depending on their security setting for the zone detected for your site
I will suggest that you just wrap the call inside updatepanel and use the partial postback to trigger the download prompt and progress template for displaying the loading widget. Let .net and the browser deal with it.
You can't, much less the browsers (like Chrome) who actually don't pop open a download file dialog. What you should probably do is simply attach to the 'ready' or 'loaded' event on the page and hide the widget when that event occurs.
Tejs is correct. IE 9 doesn't do a modal dialog anymore either. What you can do is set up a download progress watcher and programmatically hide the overlay once the watcher sees data is being sent to the client.
Can you use a hidden HTML form element reporting a DOM event such as onload or onfocus? I set some of these hidden fields in formmail.php from tectite.com, which sends email from a page to a mailbox on the server.
Well, I don't think you can do that. "The Download File Box" is a browser feature. What you should do is call the hideLoadWidget() right after you call the download.
Is there any way of removing a section of a website without altering the code?
For example, I create a webBrowser control in my Windows form and tell it to load stackoverflow.com. Would there be any way of removing the top 100 pixels from displaying?
You could write your own html page with an iframe in it, load the site (e.g. stackoverflow) in the iframe and set the css margin-top property for the iframe to "-100px"
The best I can come up with would be to have a panel overlap the top 100 pixels of the WebBrowser control.
hiii
I am developing a window application in which I am showing a web page using c# .net browser. since my web page is quite heavy and its taking time to load . so i want to show loading image while navigating a web page .so tell me how should i do .
I assume that you are using the WebBrowser wrapper, is that correct?
You can use the ProgressChanged and/or Navigating + DocumentCompleted events.
As an asside:
Depending on the nature of your application you could pre-download parts of the page to improve the user’s pereption of the app’s responsiveness.
It may sound overly simple, but it might be the easiest solution to just add an image control with an animated bitmap to the form at runtime when the page starts loading. Once it's done, just hide the image again. This would also give you the flexability to display any messages you want and add effects/transitions to make it aesthetically pleasing.
Only since you asked so nicely.
You could just do this by monitoring both the navigating and the documentcompleted events of the webbrowser control. (Im sure you can fill in the blanks here).
Be sure when you use the documentcompleted event that you check the readystate :
theBrowser.ReadyState == WebBrowserReadyState.Complete
Otherwise the documentcompleted event will fire multiple times even before the entire page has loaded.
First create an image(give a name for it) and place it wherever you want it but make the Visibility to Collapsed.
Then in your browser_Navigating, add this code, ImageName.Visibility = Visibility.Visible;
and then in your browser_Navigated, add this code, ImageName.Visibility = Visibility.Collapsed;
Is there any builtin control in ajax to show process indicator. Like when i press copy button in my page one popup shuold come and show a small process animation gif.
is it possible in ajax using c#?
Some time ago I need to do this in my web site and I've found this page. Check this out and see if fits to your needs.
