Hi,

As Tony mentioned that if embedded editor provider is used, then editing and rendering is defined not by grid, but by editor. So, the only way around is to modify that editor (better to say: hack into its logic). All aspects of "embedded" features are defined by
Infragistics.WebUI.Shared.IProvidesEmbeddableEditor. There are few methods on server and few methods on client. You will be interested in the getRenderedValue and RenderValue members.

To adjust value provided by editor after user edited cell, you need to override the getRenderedValue member function. Example below will limit number of digits after dot to 1.

To support rendering of initial values is more complex. You need to remove WebNumericEdit from aspx, extend it and override its RenderValue. Below is example:

public partial class MyPage : System.Web.UI.Page
{
  // all your codes here

  private MyWebNumericEdit WebNumericEdit1;
  protected override void OnInit(EventArgs e)
  //or
  //protected void Page_Load(object sender, EventArgs e)
  {
     this.WebNumericEdit1 = new MyWebNumericEdit();
     this.WebNumericEdit1.ID = "WebNumericEdit1";
     this.WebNumericEdit1.ClientSideEvents.Initialize = "WebNumericEdit1_Initialize";
     this.Form.Controls.Add(this.WebNumericEdit1);
  }
}

internal class MyWebNumericEdit : Infragistics.WebUI.WebDataInput.WebNumericEdit
{
   public override string RenderValue(object value)
   {
       string val = base.RenderValue(value);
       int dot = val.IndexOf('.');
       if(dot > 0 && dot + 2 < val.Length)
           val = val.Substring(0, dot + 2);
       return val;
   }
}
