title: How to change the Numeric seperator in DataGrid?
body: <p>I have an query with number format.When changed the decimal separator(.) ---> (,) by using Region settings, type the (1.5) in excel sheet it will changed as (1,5) correctly.<br>
  My problem is in DataGridView control, I followed the same procedure in DataGrid , but it displayed (1.5) ---> (15). The (,) operator has removed. I need to know, is this the actual behaviour of the DataGrid. Can we perform same like as excel? I have tried below code.</p>
  
  <pre><code>Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
  Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US");
  
  CultureInfo culture = CultureInfo.CurrentUICulture;
  culture.NumberFormat.NumberDecimalSeparator = ",";
  culture.NumberFormat.NumberGroupSeparator = ".";
  </code></pre>
  
  <p>Please refer comparison image of excel and DataGrid
