Hi Priya Priya,

Please review the Chart documentation section which explains how to configure the legend items and set exploded property to a series item. Let us know if you are experiencing any specific problems during the implementation.

Hello Priya,

I believe the problem is coming from the fact that you set the DataSource property, which means that the items you've set in the report designer would be wiped out. You would have to manually traverse the data and set the needed properties in the NeedDataSource event, e.g.:

......
            ChartSeries s = chartDef.Series[0];
            s.Clear();
            s.Appearance.LegendDisplayMode = Telerik.Reporting.Charting.ChartSeriesLegendDisplayMode.ItemLabels;
            foreach (DataRow row in table.Rows)
            {
                ChartSeriesItem item = new ChartSeriesItem();
                item.YValue = (double)row["Value"];
                item.Name = (string)row["DescriptionCol"];
                item.Appearance.Exploded = true;                
                s.Items.Add(item);
            }

Best wishes,

Hello Can any 1 tell me which dll i need to download, to use pie chart in my simple asp.net web application.
and where i will get tht dll.

I'm using the 2012 Q2 version of the standalone telerik report designer, and I'm trying to accomplish a similar task. Is it possible to set the labels of a pie chart legend to a property from my datasource?

I've seen people link to the Binding to generic lists , but this only offers a solution which programmatically sets the label in the code-behind. I need to do this in XML (aka the report designer). 


EDIT:

Answered my own question. Thanks to the great example that gets installed with reporting, I found that setting the "DataLabelsColumn" to my property fixed the issue. Just remember to have the "LegendDisplayMode=ItemLabels".

Thanks!
