look for easy way to reproduce a chart

[User (Legacy)]

Hi,

I want to reproduce a chart in a newly opened page, but if I save the chart

object as Session, it seems does not work. I noticed actually there is a

temp image file saved locally, like

SRC="/chartfx62/temp/CFT0114_02291204E06.png" , is there an easy way to get

the src and use it in another page? thanks

Michael,

If I am understanding you correctly, the best way to reproduce a chart in a 

newly opened page is to export as binary from oldPage and import as binary 

to newPage.

This will keep all your properties intact and even your data if you want.

See Import/Export API.

I don't know if this would work in your situation but...

you could store this chart in the cache

using System.Web.Caching.Cache

The only tricky part for you would be the key. The key that you use could be 

the value returned from GetHtmlTag

that string would be unique something like this

SRC="/chartfx62/temp/CFT0114_02291204E06.png"

Something like this:

string skey = Chart1.GetHtmlTag(...);

m_cache = System.Web.HttpRuntime.Cache;

MemoryStream memStream = new MemoryStream();

Chart1.Export(FileFormat.Binary, memStream);

memStream.Seek(0, SeekOrigin.Begin);

m_cache.Insert(skey, memStream, cacheDependency);

Then all you need to do later is save the key and get it later like this

Stream stream = (Stream) m_cache[skey];

if( stream != null) {

 stream.Seek(0, SeekOrigin.Begin);

 Chart2.Export(FileFormat.Binary, stream);

}

The other solution is to save the binary stream to a file.

Hope this helps.

thanks for your reply, I have done through:

this.Chart1.ImgTags = "id=img20050101 border=0";  --> set an unique id for

the image

and in html script:

var obj = document.getElementById("img20050101"); --> get the IMG object

and then I can use obj.src and point to it on another page
