Hello All,

I have this requirement. I have few products on my website which are of document type "A" and a promotional campaigns of document type "B".

I want to render document type "B" after processing 4 documents of doocument type "A"

Like this

Product Product Product Product

=====Promotional Message=====

Product Product Product

Is it possible to achieve something like this using repeaters?

Any ideas?

Regards, Chetan

Use a nested repeater within your product (doc type b) transformation. You can check if by using MOD ( % ) to see if the DataItemIndex is the 4th item and then databind the nested repeater. If you Google "nested repeater kentico" you should find some good examples.

<script runat="server">    
  protected override void OnInit(EventArgs e)
  {
    base.OnInit(e);
    if (DataItemIndex % 4 == 0)
    {
        nestedRepeater.WhereCondition = "ProdCategory = " + Eval("CatID"); // set if needed 
        nestedRepeater.ReloadData(true);
    }      
  }
</script>

Thanks Brenden for the reply, lot of people on various forums are suggesting using Hierarchical Transformation instead of Nested repeater because of its inherent better performance.

What do you think about it? Any idea how it can be accomplished using hierarchical viewer?

Can't get it working. Below is my code that I added inside the transformation of the Outer repeater. I also set the property Nested Controls ID to nestedRPT. I get only this text "Nobody" which is the value for "ZeroRowsText". Also tried various combinations for path also like "/%", "/Cattle/%" and others.

<cms:CMSRepeater ID="nestedRPT" DelayedLoading="true" DataBindByDefault="false" EnableViewState="false" runat="server" Path="/Cattle/Products-Offer/" TransformationName="pm.ShowProductOffer.productoffer" ClassNames="pm.ShowProductOffer" HideControlForZeroRows="false" ZeroRowsText="Nobody" />

If you're data is in a hierarchical format then yes using the hierarchical viewer or universal viewer will work well.
