How can I find the maxlength of the number of items?
TemplateBeginIf cond="TemplateRepeatIndex == 0"
You need to use the CollectionLength function:
@@CollectionLength("Component.Fields.multiValuedField")@@

I got the error Variable 'CollectionLength' has not been declared. How to declare it? – wiske Sep 8 '15 at 9:24

I'm afraid it was added in the later version. You will probably have to implement it yourself – Andrey Marchuk Sep 8 '15 at 11:03

Check this extension, might do the trick for you: sdltridionworld.com/community/extension_overview/… – Nuno Linhares♦ Sep 8 '15 at 11:46
Why not write a C# TBB to check the number of Items, In case you cannot use any external tools.
Example:
Item compItem = package.GetByType(ContentType.Component);
XmlDocument Links = new XmlDocument();
Links.LoadXml(compItem.Content.OuterXml);
XmlNodeList OuterImageCount = Links.GetElementsByTagName("OuterImage");
string Count = (OuterImageCount.Count).ToString();
package.PushItem("ItemsCount", package.CreateStringItem(ContentType.Text, Count));
And in DWT you can read the ItemsCount item pushed to Package as:
Reading the value inside condition as:
<!-- TemplateBeginIf cond="TemplateRepeatIndex == ItemsCount" -->
And in case you want to use the value any where else in DWT, use: @@ItemsCount@@
Where OuterImage is the repeating element as
<OuterImage>

</OuterImage>
<OuterImage>
<LinkUrl>http://www.google.co.in</LinkUrl>
<Image>xlink:title="primary-icon-8" xlink:href="tcm:218-12169"></Image>
</OuterImage>
....
....
<OuterImage>
<LinkUrl>http://www.google.co.in</LinkUrl>
<Image>xlink:title="primary-icon-9" xlink:href="tcm:218-12170"></Image>
</OuterImage>
