Formatting columns in the DevExpress ASPxGridView?

Does anyone know how I could format columns in the DevExpress ASPxGridView. What I have is a xml file that is generated daily from an xml file. What I would like to do is format columns for specific values, for example, a column with measurements, I want to add trailing zeros if these are not filled, i.e. 1.2 to 1.200. I have only come across examples done in the ASPX page and have built my columns in code. Please assist with the simplest solutions or property, thanks.

In code behind you can use CustomColumnDisplayText event: 

protected void Grid_CustomColumnDisplayTextEvent(ASPxGridViewColumnDisplayTextEventArgs e)
{
    if ("ColumnName".Equals(e.Column.FieldName))
    {
        e.DisplayText = someFormatFunction(e.Value);
    }
}

Method documentation: http://documentation.devexpress.com/#AspNet/DevExpressWebASPxGridViewASPxGridView_CustomColumnDisplayTexttopic

No need to do it in an event. This is not complete of course but you get the idea:

void doStuff(){
   theGridView.DataSource = getDataSource();
   theGridView.DataBind();

   foreach(GridViewColumn gvc in theGridView.Columns)
   {
      String strSomeParamter = "";
       if(gvc.Name.Contains("$")
          strSomeParameter = "currency";
      (gvc as GridViewDataTextColumn).PropertiesTextEdit.DisplayFormatString = getTextFormatStringBasedOnSomeParameter(strSomeParamter);
   }
}

String getTextFormatStringBasedOnSomeParameter(String someParam){
  switch(someParam)
  {
     default:
          return "";
     case "currency":
          return "{0:c2}";
     case "percent":
          return "{0:p2}";
  }
}

In your .aspx page you can do this to format your column to dollar amount with 0 decimal place

  <dx:GridViewDataTextColumn FieldName="YourFieldName" VisibleIndex="1" Name="Displayame">
      <PropertiesTextEdit DisplayFormatString="${0}" />
  </dx:GridViewDataTextColumn>

In Code behind bind CellEditorInitialize to a custome event handler something like:

 ASPxGridViewData.CellEditorInitialize+=new DevExpress.Web.ASPxGridView.ASPxGridViewEditorEventHandler(ASPxGridViewData_CellEditorInitialize);
protected void ASPxGridViewData_CellEditorInitialize(object sender, ASPxGridViewEditorEventArgs e){
if (e.Column.FieldName == "YourFieldName") {
    e.Editor.Value = string.Format("${0}", e.Value);
}}
