can see only broken image for the chart

[sudha]

Hi,
  I was trying to use the chart control in my sharepoint webpart but i can see only a broken image.
  i have copied the RadChart.Net2 dll to the  gac and the safe control entry is given below
  <SafeControl Assembly="RadChart.Net2, Version= 3.1.2.0,Culture=neutral, PublicKeyToken=d14f3dcc8e3e8763" Namespace="Telerik.Charting" TypeName="*" Safe="True" />
  <SafeControl Assembly="RadChart.Net2, Version= 3.1.2.0,Culture=neutral, PublicKeyToken=d14f3dcc8e3e8763" Namespace="Telerik.WebControls" TypeName="*" Safe="True" />
  I have copied the radcontrols folder to "C:\Program Files\Common Files\Microsoft Shared\web server extensions\wpresources"
  and my code is :

  public class CustomerPortal : System.Web.UI.WebControls.WebParts.WebPart
    {
        RadChart radChart = new RadChart();                        
        protected override void Render(HtmlTextWriter writer)
        {         
            EnsureChildControls();
            RenderChildren(writer);                                  
        }
        protected override void CreateChildControls()
        {                      
            // Create a ChartSeries and assign its name and chart type

            ChartSeries chartSeries = new ChartSeries();
            chartSeries.Name = "Sales";
            chartSeries.Type = ChartSeriesType.Bar;

            // add new items to the series,
            // passing a value and a label string
            chartSeries.AddItem(120, "Internet");
            chartSeries.AddItem(140, "Retail");
            chartSeries.AddItem(35, "Wholesale");
            radChart.Series.Add(chartSeries);   
                         
            radChart.RadControlsDir = "~/_wpresources/RadControls";
                             
            this.Controls.Add(radChart);                   
        }                                                  
    }
 I have the trial version (zip) of your controls.  
   Please help.
Thanks,

Hi sudha,

Your configuration seems correct. I just want to check several things:
-Have you tried the following path (no ~): radChart.RadControlsDir = "/_wpresources/RadControls";
-Can you make sure sufficient access priviliges were given to the RadControls dir and all its files?
-Can you make sure the RadControls dir is not configured as a web application?

If you are continuing to have problems you can try to access the chart image URL directly and observe the http response for more information.

Kind regards,

I am experiencing exactly the same issue.  I have checked all the things in the second post, to no avail.  Is there anything else that could be doing this?

Hi AECLDEV,

Have you followed the relevant steps from this tutorial? Have you excluded file access permissions from the list of possible problems?
