The AutoGenerateColumns of the grid are enabled by default. To modify their settings or implement some custom logic in the code-behind, you can use the OnColumnCreated event handler:
Customizing auto-generated columns
Using the e.Column.UniqueName property within this handler causes the grid to generate and assign this name explicitly. The internal auto-column generation logic afterwards may append 1 at the end of the column name since it finds an already existing column with the same name.
This may lead to the following error:
Cannot find a cell bound to column name "MyColumnName".
To avoid this, instead of accessing the UniqueName of the auto-generated column, you can use its DataField property.
sender, GridColumnCreatedEventArgs e)
IGridDataColumn column = e.Column
currColumnField = column.GetActiveDataField();
//instead of using e.Column.UniqueName
//as this usually be the same for autogenerated columns
