Hi,

Editors use .net standards for its formats. Unfortunately usage of those "format" objects needs some experience. You may configure culture for whole application using CurrentThread.CurrentCulture, or you may customize every particular instance of editor. Since .net does not support view state of CultureInfo, all custom formats are possible to implement only in codes behind for every load. Below is example for Page.OnLoad event:

System.Globalization.CultureInfo ci = System.Globalization.CultureInfo.CreateSpecificCulture("en-US");
System.Globalization.NumberFormatInfo ni = ci.NumberFormat;
ni.NumberGroupSizes = new int[]{0};
this.WebNumericEdit1.NumberFormat = ni;
