Line 57: dim product as DataRow
Line 58: product= cartoperation.GetProducts(ProductID)
Line 59:
Line 60: dim shoppingCart as cartoperation.OrderList |
thanks
Updated Code
Since the output of your GetProducts method is a DataTable, you have to define product as a DataTable as well:
Dim product As DataTable
product = cartoperation.GetProducts(ProductID)
can you please say
Sir, can you please see this error?

Line 126:
Line 127: dim ProductID as integer
Line 128: ProductID = int32.parse(productListing.datakeys(ProductListing.selectedindex).toString())
Line 129:

When i selected a particular category, to browse through it, the error occured, what can be the reason?
thanks for all your help
Updated Code
Instead of using the SelectedIndex of the ProductListing object, try using the SelectedValue:
ProductID = int32.parse(productListing.datakeys(ProductListing.SelectedValue).toString())
it says selectedValue is not a member of datalist

You might get this error if you miss out on giving the Datakeyfield for the DataList
i have given
but i have given datakeyfield value for the 2 datalists which i am using
then why is this occuring
can you please guide me
thanks
Sushila Patel replied to F Cali
DataList.Selected value is new in .NET Framework 2.0
If you are using 1.1 and you are writing code in the Item_Command/Item_DataBound event or so
you will use e.Item.ItemIndex
So in code with appropriate event that you trigger
it should be
ProductID = int32.parse(productListing.datakeys(e.Item.ItemIndex).toString())

Page Level error in Asp.Net Hello, I want an example of PageLevel Errors in asp.net. . . . With explaination. . . . Thanks in advance. . . From my point of view, you should do error handling both on page level appliation level. It does not look good if you show a generic error even if a user inputs simple wrong data in a field. The error message should be meaningful. For all know type of errors, you should provide page level error handling and in case if any new exception rises, then there is always the application level handling. http: / / forums.asp.net / t / 1648098.aspx / 1 Hi, Every time you create a web form in Visual Studio
