I want to be able to apply custom formatting for some of the columns in the UltraGrid.

• I am using UltraDataSource which has some columns of the double type
• I am assigning this data source to UltraGrid which displays columns automatically
  

I want some of my double columns to be formatted in a specific way:

• If the value is round, it should be displayed as is, for example 128.(0) should be displayed as simply 128
  
• If the value has a fractional part, it should be displayed as a multiple of 1/32, for example 128.21875 should be displayed as 128.7/32

I also want this values to be editable and displayed in the same format while editing.

There is a way to achieve this for the standard Microsoft data grid by overriding the following methods of the DataGridTextBoxColumn:

• GetColumnValueAtRow
• Commit
