The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Rank: Master

GreenGhost:

That is not possible. When the server code starts, it has already been determined where the page will open. Once the request has been sent, it's too late to change where the response will go.

You have two alternatives:

1. Open the page in a new window instead of doing a postback. This has to be done in the browser before the page is requested.

2. Return a page that contains a Javascript that opens the document in a new window. You can use the Page.ClientScript.RegisterStartupScript to add Javascript code to the page.

amillyard:

GreenGhost: ok, filename is picked from a datagrid row -- so that button press initiates the db call to collect the filename / location details -- when then calls the above procedure to display the document.

just confirming -- does that mean option 2 is more suited?

03.09.2008 at 04:03PM PDT, ID: 21083068

amillyard:

when I try the attached I am getting the current web-page and document merged into the same web-page (same browser window)

                       
             Page.ClientScript.RegisterStartupScript(GetType(), "test", "window.open('" + hostedSubFolderLocation + "','Height=300px,Width=700px,menubar=No,toolbar=no,scrollbars=yes');");

Open in New Window

GreenGhost:

You forgot the target parameter in the window.open call. Also the width and height of the window should not have the css unit "px".

Page.ClientScript.RegisterStartupScript(GetType(), "test", "window.open('" + hostedSubFolderLocation + "','_blank','Height=300,Width=700,menubar=No,toolbar=no,scrollbars=yes');");

Have you removed the Response.WriteFile call?

03.12.2008 at 01:22AM PDT, ID: 21103878

amillyard:

"Have you removed the Response.WriteFile call?" do I need to remove this scripting? if so, how would I then display the document? (or is the naem of the file added to end of hostedSubFolderLocation ?

GreenGhost:

> do I need to remove this scripting?

Yes.

> if so, how would I then display the document?

It's displayed in the new window that is opened by the Javascript.

> or is the naem of the file added to end of hostedSubFolderLocation ?

What you should use in the javascript, is the virtual path to the file, i.e. the same that you would use in a link.

If the document is in the same folder as the page, it's simpy hostedFileName:

Page.ClientScript.RegisterStartupScript(GetType(), "test", "window.open('" + hostedFileName + "','_blank','Height=300,Width=700,menubar=No,toolbar=no,scrollbars=yes');");

amillyard:

GreenGhost: have made the adjustments as attached.

but 1. no new browser opens, and 2. the document and web-page are merged together (in the same browser window)

GreenGhost:

Also comment out the code that sets the content type. As the document is not returned in the response, you should not change the content type of the response.

The url that you use in the window.open method is a virtual path, so it uses slash (/) as separator, not backslash (\).

You have to add another parameter in the RegisterStartupScript call. You need to send the value true for the addScriptTags parameter, so that a script tag is added around the Javascript code.
