The TreeListCustomColumnDisplayTextEventArgs.DisplayText property contains a cell’s current display text. To customize the display text, assign a string value to this property.

<dxg:TreeListColumn FieldName="Value"/> 
void treeList_CustomColumnDisplayText(object sender, TreeListCustomColumnDisplayTextEventArgs e) {
    if (e.Column.FieldName == "Value")
        e.DisplayText = string.Format("{0:n2}", e.Value);
}
