title: Why does my ColumnHeadersDefaultCellStyle keep being reset in Visual Studio designer?
body: <p>I am trying to make the column headers of my DataGridView bold, in Visual Studio 2008.</p>
  
  <p>Every time I change my ColumnHeadersDefaultCellStyle to Calibri 9.75pt bold, using the properties box, the next time I reopen the saved form, the ColumnHeadersDefaultCellStyle has reverted to Calibri 9.75 without bold.</p>
  
  <p>My form's font is Calibri 9.75 without bold, as is my default cell style, but I should be able to override the default cell style with my ColumnHeader style right?</p>
  
  <p>I can solve this problem programmatically by setting the style when the form is shown, but we would like to have the Visual Studio designer show the bolded headers, so we can layout the columns appropriately for the space taken up by bold header text.</p>
  
  <p>In addition, the actual designer file specifies that the ColumnHeadersDefaultCellStyle is bold, even though the designer interface says it is not bold.</p>
  
  <pre><code>dataGridViewCellStyle1.Font = new System.Drawing.Font("Calibri", 9.75F,  
      System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
  dataGridViewCellStyle1.ForeColor = System.Drawing.SystemColors.WindowText;
  dataGridViewCellStyle1.SelectionBackColor = System.Drawing.SystemColors.Highlight;
  dataGridViewCellStyle1.SelectionForeColor = System.Drawing.SystemColors.HighlightText;
  dataGridViewCellStyle1.WrapMode = System.Windows.Forms.DataGridViewTriState.True;
  
  this.receiptDetailView.ColumnHeadersDefaultCellStyle = dataGridViewCellStyle1;
  </code></pre>
