Ashwini,
I would like to ask you what the problems did you encounter? You didn’t tell me any problems in your application about the class break style. Also if you let our helps on your application please attach your whole solution with shape files, please don’t just send the code snipped to us, we cannot get any useful information from the code snipped.
Thanks,

Hello,
Actually i want to highlight various reagions according to area ranges with different colors.
For that i am using class break style.I want code for highlighing those areas accoring to ranges of areas.How to do that using classbreakstyle.Will you provide me some guidline code regarding that.plz
ashwini,
I'm sorry that I can't understand what's your real requirement. From your code snippet and screenshot I understand your procedure, but I don't know what do you mean by "highlight various reagions according to area ranges with different colors.", it seems that the ClassBreakStyle in your code has used different colors to display areas in your shape file.

Ivan
hii...
Exactly what you are thinking..I am using classbreak style for displaying various regions with diffrent colors..
I will explain it again.I have popoulation field in country shape file.I am breaking population into 4 ranges.that is 1 to 5000,5001 to 10000,10001 to 15000 and 15001 to 20000.And i am using 4 different colors to display those regions on city.shp layer of winformmap control.so i am using classbreakstyle by that i am breaking population in above ranges and applying various colors.My snnipet is showing code that i have done with some explanation.When i run this code i am not able to show those result on map.Will you help me..please.
If again you failed to get my doubt.plz tell me again.
Hi Ashwini,
The ClassBreakStyle is the best option for you to rend different colors based on the value ranges. And seems like you are setting it up correctly from your code snippet.
But it’s not working for you, so I am wondering: what’s the result on your app when you click “Result” button? The city symbols are rending in the same color or they didn’t show up at all? Or something else? It’s hard for us to dig into if we don’t know what’s the result in your app and what’s the problem you are running into.
Also we can check those items very quick.
1. I noticed you are using the PointStyle into the ClassBreak, let’s double check the data you are rending is a Point Type data. If it is an Area Type data, please use AreaStyles
2. Double check the range 1- 20000 covers the records in your data(at least covers some of them)
It will help and speed up a lot if we got a sample as well as data from you to reproduce your problem.
Please feel free to post the problem you have and we will do what ever we can to help.
Thanks,
Lee
