---

Hi smarx, I check it.. They asked me to change

From   
<add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempImageFiles\;" />

To
 <add key="ChartImageHandler" value="storage=file;timeout=20;" />

in web config file...

But I don't have this line in my web config

I have only this for defining chart

<add name="ChartImg" verb="*" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler,     System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"  />
<add name="ReportViewer" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler,Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

What should I do now....

Answer 1

Do the followings

1) Add or Edit the following key in web.config.

<add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempImageFiles\;" /

2) Give writing privilages to IIS_User to this directory, for that do the followings:

a) Go to Windows Explorer.
b) Right click on c:\TempImageFiles Folder.
c) click Properties.
d) Select security tab , click Edit, click Add , Click Advanced, search for IIS_User.
e) Add this IIS_User , give write permission to this user.
f) Save and Close.

Now you have set the directory and given write permission to IIS to write temporary image files to this folder.

It should work now.

Time still progresses and people still have recommendations. I came across this issue during a migration, so I thought I'd add my two cents.

Why store it in the file system and not just keep it in memory?

<add key="ChartImageHandler" value="storage=memory;deleteAfterServicing=true;"/>

If the file system is an issue in Azure, then don't use it.

Answer 3

I had the same issue, my problem was my provider had special folders with write rights, so I changed the TempImagesFile folder to their default folder and it worked.

In my case the folder with write rights was called upload

web.config edits:

<appSettings>
    <add key="ChartImageHandler" value="Storage=file;Timeout=20;Url=~/upload/;"/>
</appSettings>

Hope this can help other too ;)

Answer 4

try to add this key to your web.config

 <add key="ChartImageHandler" value="storage=file;timeout=20;" />

instead of the default one:

<add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempImageFiles\;" />

Answer 5

Update your app setting to this and see if that fixes your problem

 <appSettings>
    <add key="ChartImageHandler" value="storage=file;timeout=20;deleteAfterServicing=false;privateImages=false" />
    <add key="ChartImageHandler" value="storage=memory;deleteAfterServicing=true;"/>
  </appSettings>

Answer 6

If changing the following line

<add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempImageFiles\;" />

to

<add key="ChartImageHandler" value="storage=file;timeout=20;" />

not works, then change the value of attribute "storage=file;" to "storage=memory;" . It will surely work because now you are using memory, instead of file.
