Hi,
The chart control seems to store cached images in a folder called ChartImages, is it possible to disable this, because having an images folder means the installer needs to make sure that folder is writable.
I'm just trying to make my web app as easy as possible to install.
CheersVictor
Victor,
You can use session-based deployment instead. For more information, please refer to the following article from our online help documentation of NetAdvantage for Web Client (ASP.NET) 2009 Volume 1:Image Deployment in WebChart
There may be scenarios where session-based deployment may not be an option. For instance, if you're deploying to a web farm, and if you're not using ***ion server to ensure that all the computers on the farm share the same sessions, then session-based deployment won't work.
Is there an example of how I should write the SecureImagePipe file?
this is a bug. i logged it in our bug tracking system (issue #20600) and fixed it. it will be resolved in a future service release.
feel free to contact Infragistics Developer Support at any time to inquire about the status of this bug.
"place an instance of the SecureImagePipe on the page" was really vague, so to save others a lot of time...

On to my question:Why doesn't "~/ImagePipe.aspx" work? I want to create one ImagePipe.aspx file, to be used anywhere on my site. Do I have to create an ImagePipe.aspx file in every folder containing a page that uses a chart?
To write the SecureImagePipe page, create a single page, with no master page, and place an instance of the SecureImagePipe on the page. This page will never be displayed directly to the user; it's sole use is to route chart data from the server to the client. Because of this, you don't need to put anything else on the page.
Next, on your page containing WebChart, ensure that the chart's ImagePipePageName property refers to the page you just created.
To make this easier, you can name your SecureImagePipe page "ImagePipe.aspx", which is the default value for the chart's ImagePipePageName property.
