Hello all,
I need a way to be able to dynamically add products on a public (logged in user) page. I have created the page and copied much of the code from the Usercontrols/_EditProduct.ascx page to get the required functionality.
When I visit the page with ?ProductID=0, everything displays properly except the Name, Description, and Strapline textboxes were missing. I Added textbox fields for these. When I click the 'Save' button, nothing happens. In the log I get the error:
System.NullReferenceException: Object reference not set to an instance of an object.
at _LanguageContainer.ReadContent()
at Customerebooks.SaveProduct(DML_OPERATION enumOperation)
at Customerebooks.btnSave_Click(Object sender, EventArgs e)
at System.Web.UI.WebControls.LinkButton.OnClick(EventArgs e)
at System.Web.UI.WebControls.LinkButton.RaisePostBackEvent(String eventArgument)
at System.Web.UI.WebControls.LinkButton.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument)
at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument)
at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
Here is my code:

I believe the error is coming from vb line 332
"tblLanguageContents = _UC_LangContainer.ReadContent()"
I'm guessing the built in name, description, and strapline textboxes are in the LangContainer so since mine are not displaying, it cannot read the contents and thus returns null. How can I correct this?
Thank you all!

The language container is for fields that are language specific. These appear in a tabbed dialog, one tab for each language. In this way, creating or editing things such as products incorporates multiple fields for product name, etc. if there is more than one language.
I am not sure really from looking at your code why the language boxes don't display, but it's vital to get those working correctly and displaying because updating products without those is going to be hard because all our code is based around having those.
Another solution might be to consider using the web API to create products? You would then have more freedom to design your own form, and then make web service post to create or edit the product.

Thank you Paul,
I dug a bit deeper in the _LanguageContainer code and realized that was an integral part to getting the form to post. Just can't figure out why it isn't displaying.
If I were to try the API route, what method would I need to call? What are the parameter formats/values?
Thanks again!

I am using essentially the exact code from usercontrols/_EditProducts.ascx
The only differences are - I'm inheriting PageBaseClass instead of System.Web.UI.UserControl
- I have the code in a aspx page that uses the site skin as a Masterpage
Could either of these make a difference?

Ok, so it look like to do this via the WebAPI, I need to call this function:
Public Shared Function _AddProduct(ByVal ptblElements As DataTable, ByVal pParentsList As String, _
ByRef pProductID As Integer, ByVal pLive As Boolean, ByVal pFeatured As Byte, _
ByVal pOrderVersionsBy As String, ByVal pVersionsSortDirection As Char, _
ByVal pReviews As Char, ByVal pVersionDisplayType As Char, ByVal pSupplier As Integer, _
ByVal pProductType As Char, ByVal pCustomerGroupID As Integer, ByRef strMsg As String) As Boolean
so I would use. strMethodName = "ProductsBLL._AddProduct"?
And my strParametersXML would need a value for every parameter listed in the function?
My problem remains with the language Contents. What is in the ptblElements Datatable so that I can recreate it to pass in the XML Parameter?

Can anyone please share some advice?
How can I use the API to add a product. Specifically what data has to be passed to the API and how do I determine what goes into the ptblElements DataTable?
Thank you!
