Can anyone tell me how to solve this problem... Should I have to create a temporary directory manually or what should I do...

Hi smarx, I checked 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 a 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

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\;" />
