How do I create Harvey Balls in Telerik Reporting?

Hi Greg,

Most probably your colleague submitted the same inquiry. Below is a quote from my response:

"The feature is not available in Telerik Reporting. Please feel free to log a feature request for having such in future. Features are considered based on the community demand for them.

I can suggest you the following workarounds:

1. Use 4 images representing the different values 0-4 and a PictureBox item (can be the Style.BackgroundImage of another item as well). Then use a binding to the Value or BackgroundImage property based on a field that determines which image to be used e.g.:
   

   //PictureBox item
   Property Path:Value
   Expression: ='http://mysite/resources/'+Fields.[0To4Field]+'.png'

2. Use a Graph item - How to: Create Pie chart, where you will need to have two values to generate the circle."

I hope this information is helpful.

Regards,

Here is what I ended up using.  Unicode characters producing Harvey Balls:

 

private char GetHarveyBall(decimal percent)
{
//Empty Circle
if (percent < 0.20M)
return '\x25cb';

//Quarter Circle
if (percent < 0.40M)
return '\x25d4';

//Half Circle
if (percent < 0.60M)
return '\x25d1';

//Three Quarter Circle
if (percent < 0.80M)
return '\x25d5';

//Full Circle
return '\x25cf';
}
