I need to know a way to process images in asp.net web pages. I need to be able to highlight a certain area of the image and put an image on top of the other, then save the image with those changes. So far everything I have seen requieres buy 3rd parties components which I can not afford, I need to develop this functionality using objects inside the .net framework, or a free component.

i'm new to asp.net, but familiar with c#, .net. i want to write a cms for asp.net, which has the pages of the website in a database. these pages contain asp controls, like asp:Repeater which have to be processed after loading the page from the database, and before sending it to the client like a normal aspx page.
View 1 Repliesi'm developing a site using VS2010 and with my windows vista busniness OS. i used the default VS2010 wizard for new web application to create it. included a folder in the root directory and created new aspx pages to derive from the master page in the root directory of my site. everything shows on the new pages except the jpeg image logo in the master page. But other aspx pages i created in the root directory shows every thing fine.

View 1 RepliesWorking on an ecommerce site which will be integrated with a 3rd party vendor--that vendor uses different identifiers for stores than we use internally (i.e. their store ABC123 is our 001-321). I'm researching the best approach to inspect incoming requests for reserved query-string parameters that indicate the request is using their identifiers and map the identifiers back to our identifiers (so if the request is example.com/&theirId=ABC123 I want to transform the request to example.com/&ourId=001-321). To do this mapping I need to inspect the provided ID, execute a lookup against the database or cache, and forward the request to the specified page--limiting the modifications to just the query-string parameters (other parameters will need to be maintained, as with the details of the HTTPHeader, etc). So far I'm researching a few different approaches: Implementing it in a base Page (which already does too much, but has the benefit of our Logging infrastructure and some other injected dependencies) Implementing it in an IHttpModule Using URL RewritingUsing URL Routing (looks like routing isn't what I want, feel free to offer insight if you think it still fits) Performance cost is a consideration: the actual number of times this translation will occur will be very small compared to the number of requests not requiring it--perhaps 1%. However for another integrated site we will perform this mapping on nearly every request--would a different approach be better suited to this scenario from the previous?
View 3 RepliesI have a requirement to show an Exit Popup on one of our processing pages. I am showing the exit popup by registering a client side javascript like
window.onbeforeunload = ShowExitPopUp();
The popup executes fine if you close the window, or try to type in a different URL. However the issue is that my processing page is also performing a "Response.Redirect" on the server side once the process completes. When response.redirect happens the exitpopup also shows up. Is there a way to have the exit popup not show up in that case?
Since my server side code is running through an UpdatePanel, so I have tried registering the following, in an attempt to remove ExitPopup from client side. However this doesn't work since server side redirection happens before end request.
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RemoveExitPopup);

I want to show processing .gif image while submitting data or fetching data?
For example,When we search for hotels in any city after clicking search we have a model popup which ask you to wait and shows processing image.
We are in the process of building a huge site. We are contemplating on whether to do the processing of HTML at server side (ASP .Net) or at the client side. For example we have HTML files which acts like templates for the generation of tabs. Is it better for the server side to get hold of content section (div) of HTML load the appropriate values and send the updated HTML to the browser or is it better that a chunk of data is passed onto client and make Javascript do the work?

The above code contains an image tag in header of the master page..
whenever I open a new web form linked with this master page.. the existing image doesn't open or isn't displayed..
And one more ques... the overall contents of the web pages are moving beyond their original locations after being run the program.. whereas the contents are in their own locations before execution.. How can I make them static to view??
I am using VS2008 and want to display a login page with a background image. If I add the image to the page's body and name the page login1.aspx, it displays fine. However, when I change the name to login.aspx, I can see the background in design mode, but the background image does not display when run (debug or otherwise).
I try the same thing using a div or asp:panel and get the same results. I read a post where someone else was having similar problems; however, no answer was given other than blaming VS2005.
I have a HTML IMG tag on my master page and there are aspx pages in the same folder which access this master page and it works fine.but if i have aspx pages in sub folder(inside root) which access the master page,the IMG doesnt work,the master page is in root folder.

View 10 Replieson the following.I am having a requirement for three GridViews (GV1, GV2 and GV3) to be nested within each other , GV3 being the inner most and GV1 being the outermost. The 3 GridViews are populated from non-SQL datasourse. Each Gridview has only column.A dropdown listbox is provided on the page and the value selected (say ID1) from the dropdown listbox is used as a filter for the query used to get the data from the database to populate GV1. The ID for each row displayed in GV1 will be used as a filter for the query used to poplulate GV2. ID2 for the row displayed in GV2 is used in the query used to populate GV3. GV3 will display rows of llnk buttons. When the user clicks on a link button in GV3, I want to be able to retrieve all the three IDs (ID1, ID2, and ID3) for further processing. The rows displayed in GV1 and GV2 will have different background colors.
