Web Forms :: Open A File In DataGrid Using Linkbutton?
Jun 24, 2010
I am having gridview in my UpdatePanel template to avoid postbacks. I used linkbutton in my one of file path column to open selected file. My file path column contain file names with various extensions like pdf,jpg,doc..etc in each row. Whenever i clicked the corresponding file name i want to open the file in separate window but don't let the user to save the same file.Because i am having another column,which has download button to save the file.
I kept the open link and download button in seperate two columns inorderto get the datetime to open and downloading to maintain logs into database. In order to achieve that i have to use RowCommand event of datagrid.
I have left menu navigation which is a datagrid. They are linkbuttons. When clicking it, it will display related data based on the value passed from the link. But if the passed value is a specific value, it is not displayed data in the right pane; instead, it will displayed a submenu of the link.
There is a textbox , button and gridview(contains linkbutton in template field) in my webpage. If the user enter some text in the textbox and press button means it will search the text in the interrnet and display the text in gridview (like[URL]if the users clicked the linkbutton in the gridview item i want to save the "clicked link" and "searched text" in the database.If the user clicks the linkbutton in the gridview, i captured the server side event of gridview_rowcommand and wrote the code to save the details in the database. But i cannot get the event of mouse rightclick event of "open in new tab" and "open in new window" option in server side and in javascript.how can i get the event of mouse rightclick "open in new tab" and "open in new window"?

I am creating an ASP.NET MVC Web application. Among the options are a series of LinkButtons that refer to videos. I want the user to be able to click on the LinkButton and have the video play in MediaPlayer. I do not use Silverlight in the application, because I don't want the user to have to have Silverlight installed in order for it to work.
The "fly in the ointment" for this is that I DON'T want Media Player to remain open if they are doing other things. I want Media Player to open ONLY if they click on the LinkButton.
I thought about doing this by opening a separate Media Player window, but I had two problems with that:
- how can I make the separate MediaPlayer view open?
- how can I pass the URL of the video to MediaPlayer if it's a separate view?
So I understand that the HperLink is a Client Side Control but I need code behind so that I can store the click event in the database. If I use the Link button, I have the opposite issue where I can access the client side but cannot open the url since this control does not have the NavigateUrl attribute.
I am trying to open a file share link from the window.open ... but its adding the http://localhost/vdir/ before the path can any one say what is the problem?

When the user clicks on "OPEN" button, It should open up that(.txt) file which is on the file server in ReadWrite Mode (like in notepad) without any Access Issues.
Or simply has to be openend as temporary READONLY .Txt File. So that the user can close after viewing it.

I have a folder called GUI. Inside GUI thers another folder called PDF and inside this folder, there are some PDF files. This folder (GUI) is uploaded to the server too. Then I have a WebForm with some ImageButtons. When I click one of these ImageButtons, I want the file to open in a new tab. I tried with the following code:
[Code]....
As you can see, I build the path using the tooltips of the different ImageButtons. The ToolTip = File Name I want to open. When I try this in debug mode, it works. It opens the pdf file in a new tab. However when I publish my website and upload it to the server... it doesn't work... when I click an ImageButton I get the following exception: No application is associated with the specified file for this operation
