Format font custom group

[Lucas Aguiar]

When I create a group like this:
             GroupDescriptor GroupDescriptor descriptor = new ("GrupoVencimento");
             descriptor.GroupNames [0]. ListSortDirection.Descending = Direction;
             descriptor.Aggregates.Add ("Sum (Value)");
             this.rgvContasReceberParcela.GroupDescriptors.Add (descriptor);

How do I format the font, size, style, etc.?

thank you

Hi Lucas Aguiar,

Thank you for writing.

You can use the ViewCellFormatting event of the RadGridView to set the font for the group cells and for the data cells. Consider the following code snippet which demonstrates this:

private Font normalFont = new Font("Helvetica", 10);
private Font bigFont = new Font("Helvetica", 14);

private void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
  if (e.CellElement is GridGroupContentCellElement)
  {
    e.CellElement.Font = bigFont;
  }
  else if (e.CellElement is GridDataCellElement)
  {
    e.CellElement.Font = normalFont;
  }
}

Note that the creation of a font is a heavy operation and may easily lead to performance and memory issues, so it is a good idea to create fonts only once and then reuse them.

I hope this will help. Should you have further questions, I would be glad to help. Regards,
