I'm having a real problem getting webchart print to work correctly from the browser.
The chart is displayed on the page correctly and all the click events work correctly. Yet not matter what I try issuing "window.print()" results in a page being printed with the small red cross instead of the chart. I've searched the forum and can't find any suitable samples. Do you have a working sample that demonstrates printing from the borwser using javascript.
I'm using Session as the tempchart style.

Hi Adrian,
It works fine for me doing as told here. Does it work fine at your end?
Thanks in advance.

Hi there,
this doesn't work for me, I just get a blank square with a small square in top left corner with a red cross.
even if I right click on the page and select Print from the explorer menu I get the same.
the page is correctly displayed showing the chart, it just doesn't want to print properly. I thought it might be my app thats doing something so I checked that there is absolutly no postback when the print is initiated and there isn't. It's got me stumped.
any suggestions?

Hello,
We've re-tested the technique described, using window.print() both from Internet Explorer and Firefox (and as standalone in a page or in an Ajax Update panel). The Chart prints correctly from both browsers. The Chart itself is an image on the page, so should print as any other image. If you do a Print Preview from the Browser 'File' menu, does the Chart show in the preview?
- Are there any special characteristics to your project that we most probably haven't reproduced here in our standard tests?
- Are you using one of the above two browser types?
- Is the red cross you see the same size as the Chart you expect to display (does your Chart have width and height set ie, via 'style' when right mouseclicking on Chart at designtime)?
- Are you able to send us a sample project to reproduce the problem?
- What TeeChart build number are you using?
With thanks.

Marc Meumann

Hi there,
I'm using IE 7 to display the charts. I don't believe there are any special characteristics, here is the source of the page (once displayed.
Print preview from the right click menu also shows the chart witht eh small red cross in the uppre left corner.
This problem has occurred in the last several builds including the latest 3.5.3105.20150.

Hello,
I don't see any clues in the result source of your webpage as to why the image doesn't appear. Does this problem occur with all projects including TeeChart examples and/or a new, absolutely standard Chart on a Webform project? Do you have a moment to try a new project of one Chart on webform?
I can't think that it may be a cause but it might be worth changing the Chart retrieval technique to see if any aspect of that is causing a problem (eg. TempChart property from 'Session' to 'httpHandler').
If the problem appears in a new project too, have you tried viewing the Charts on different clients to see whether all are affected? Have you tried a browser other than ie7?
regards,
Marc

Hello,
I'm having the same problem but with a curious note; If I try to print in FF 2.* then I can print very well. probably because FF is using the cache image and IE is trying to retrieve the image again from the server.
In using the mode TempChart="Httphandler", and that might be another cause, may be the image is destroyed after it has been served and when IE goes back to retrieve to print it, then it is not found and then broken link image red cross comes in place.
Any advice?
Thank you.
