[DotNetDevelopment] Column sequence not followed

[Benj Nunez]

Hello experts,

I am using a Datagridview and a collection. My goal is
to fill the datagridview with data from a collection.
Though it appears easy enough to do it, however I noticed
that the columns do not appear in the order I wish them to be.
The code looks like this:


public void loadEntries()
{
   // get the collection (all are strings)
   List<StringHolder> logs = service.doGetTSRLogs();

   if (logs != null)
   {
     // Remove auto-generated columns.
     gvTSR.Columns.Clear();

     // Make a bold header:
     DataGridViewCellStyle style =
         gvTSR.ColumnHeadersDefaultCellStyle;
     style.Font = new Font(gvTSR.Font, FontStyle.Bold);

     // Define header text:
     gvTSR.Columns.Add("Env", "Env");
     gvTSR.Columns[0].DataPropertyName = "shEnv";

     ... // more columns

     gvTSR.Columns.Add("ReleaseDate", "ReleaseDate");
     gvTSR.Columns[7].DataPropertyName = "shReleaseDate";

     gvTSR.Columns.Add("ReleaseNo", "ReleaseNo");
     gvTSR.Columns[8].DataPropertyName = "shReleaseNo";

     gvTSR.Columns.Add("CreatedDate", "CreatedDate");
     gvTSR.Columns[9].DataPropertyName = "shCreatedDate";

     gvTSR.DataSource = logs;

   }

}


When run, I expect the columns to appear in this order:


 Env   ....more columns... ReleaseDate  ReleaseNo  CreatedDate


But I got this instead:


 Env   ....more columns... ReleaseDate  CreatedDate  ReleaseNo



I checked my "beans"(class with getters and setters), and they all
even coded in a correct order as I intend them to be.
 But when I run the program, the "CreatedDate" always appear to
be between ReleaseDate and ReleaseNo even if I *explicitly*
defined that the CreatedDate column *must* appear in the 9th
index/column (or [9]). Note that all these fields are strings.

Can someone help? Is this a bug from the datagridview itself?
Thanks in advance.
