view SharePoint 2010 list field version history

In SharePoint 2010 if we want to see the history of multiline text field whose version is enabled (Appending item); We need to follow the below step:

• Create a multiple lines of text type of field with “Append Changes to Existing Text” option enabled.
• Go to edit xslt view in SharePoint Designer.
• By default, when we enabled “Append Changes to Existing Text”, it will display “View Entries…” for the multiple lines field. We will remove the “View Entries…” and replace it with version details of current field.
• In Design mode, select Xslt list view web part > click Design on the ribbon > Customize XSLT > Customize Entire View.
• Still in Design mode, select “View Entries…” and type “testtest” directly to replace it with “change”.
• Switch to code mode, find “change”, and replace it with following code.
• <SharePoint:AppendOnlyHistory runat="server" FieldName="<Field Display Name>" ItemId="{$thisNode/@ID}" ControlMode="Display" />
• Done and save the changes.

$thisNode/@ID is very important part here

Using Server Object Model

 SPListItemVersionCollection  objVerisionColl = objItem.Versions;
foreach (SPListItemVersion objVersion in objVerisionColl)
            {
                if (objVersion.IsCurrentVersion)
                {
                    latestComment = objVersion["Comments"].ToString().Trim();
                }

            }
