Hi Dapfor Team,

Could you provide the example of code with custom resolving format property (IFormat) for the class with [CompositeField] property.

For example, we have the class which described in topic: http://www.dapfor.com/Feature.aspx?id=composite_objects

How we can use different formating (IFormat) of the column values for each row in the grid?

1st row - double value with 4 digits after comma = 4.5677

2nd row - double value with 6 digits after comma = 4.678931

3rd row - double value with 1 digits after comma = 5.1

 

Thank you!

  Hello,

  You can do it in the grid.PaintCell routine:

  grid.PaintCell += delegate(object sender, PaintCellEventArgs e)
  {
      if(e.Cell.Column != null && e.Cell.Column.Id == "your column id")
      {
          switch (e.Cell.Row.ChildIndex)  //You can also use e.Cell.Row.VisibleIndex
          {
              case 0:
                  e.Text = new DoubleFormat(4).Format(e.Cell.DataField);
                  break;
  
              case 1:
                  e.Text = new DoubleFormat(6).Format(e.Cell.DataField);
                  break;
              
              case 2:
                  e.Text = new DoubleFormat(1).Format(e.Cell.DataField);
                  break;
          }
      }
  };

   

  To prevent from often DoubleFormat object creation, you can create a pool of formats or use them as members of your control.

  Best regards,
