Controls\ProductList.ascx
I have added new columns to the data grid and am now adding new Template Fields to the code behind the page. My question is how do I reference a field I added to the ProductDefinition (so a custom field). All of the code snippets I tried don't seem to work.
1. Container.DataItem["xxyfield"]
2. (CatalogItem)Container.DataItem["xxyfield"]
3. ((CatalogItem)Container.DataItem)["xxyfield"]
I also tried creating a function and used
item["xxyfield"]
Please Advise.

Hi,
Try using:
<%# DataBinder.Eval(Container.DataItem, "DisplayName").ToString() %>
Regards,

You need to use the third option but cast it to a CatalogItemsDataSet.CatalogItem. The product list control uses the DataSet representation of the product and not the strongly-type version.
((CatalogItemsDataSet.CatalogItem)Container.DataItem)["xxyfield"]
This still does not appear to be working.
If have pasted my code sample in. The field that I am looking to retrieve is Category which I have added to the Product Definition.
Please Advise.
<
asp:TemplateField meta:resourceKey="CategoryFieldName">
<ItemStyle CssClass="ProductNameColumn" /><HeaderStyle CssClass="ProductNameColumn" /><ItemTemplate><asp:HyperLink ID="Category" runat="server" EnableViewState="false" Text='<%# ((CatalogItemsDataSet.CatalogItem)Container.DataItem)["Category"] %>'NavigateUrl='<%# this.GetItemUrlString(Container.DataItem) %>'></asp:HyperLink></ItemTemplate></asp:TemplateField>Are you getting an error message or is it just not returning data?
The site returns an error.
If I go to the EventView of the Server it states: "Cannot Implicitly Convert type Object to type String. An explicit converstion exists (Are you missing a Cast?)"
Chris...
Ahh...My mistake:
((CatalogItemsDataSet.CatalogItem)Container.DataItem)["Category"].Value
I have tried that and unfortunately I am still getting the same error as above.
Joe,
I am still having an issue with this. Are you still investigating?
My main goal is to show a product thumbnail on this page.
Please Advise.
Yup, investigating this was item number 3 on my list of things to do today. Sorry it took so long to get back to you.
I have it working with the following:
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="TempLabel" runat="server" EnableViewState="false" Text='<%# ((CatalogItemsDataSet.CatalogItem)Container.DataItem)["ProductID"].ToString() %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>Also, make sure you set the "propertiesToReturn" attribute in web.config otherwise your column won't be returned in the browse and search results.
<
commerceSite ... propertiesToReturn="CategoryName,ProductID,CatalogName,i_ClassType,DisplayName,cy_list_price,myField">
...
</commerceSite>I hope this solves your problem.
Cheers,
Joe
Joe,
Unfortunately still a no go my end.

Xcel,
CatalogItemsDataSet lives in Microsoft.CommerceServer.Catalog. If you're missing this reference in your code, then this won't compile. Make sure you add the reference to this library to your solution (I'm assuming you know how to do that).
If that doesn't fix it, change that casting from CatalogItemsDataSet to Microsoft.CommerceServer.Catalog.CatalogItemsDataSet.
Thank You Joe - this solved my problem.
