This is driving me nuts. I'm trying to make a better search function for my database. I've had this working before but for the life of me I can't see where the problem is.
The error is: Public member 'Text' on type 'String' not found.

I have created a ASP.NET 3.5 web application and in it I have SearchGridView.vb class file in the directory Old_App_Code. This file creates a namespace MyApp.WebControls, which is also referenced in web.config in a namespace tag, as well as included as an import directive at the beginning of my content page. Unfortunately, I receive the following error: Warning 1 Namespace or type specified in the project-level Imports 'MyApp.WebControls' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases. Here's the first several lines of my class file SearchGridView.vb:

For this line: Imports AjaxControlToolkit
I get this error: "namespace of type specified in the Imports 'AjaxControlToolkit"
I could remove that line, were it not that it also says this line: Private _questions As CascadingDropDownNameValue
error: Type 'CascadingDropDownNameValue' is not defined.
My web.config has been upgraded, I have placed the latest ajaxcontroltoolkit.dll in my bin folder...what more can I do?

I am binding SQL data to a GridView. The GridView's DataKeyNames property is set to the SQL column called "utID"
I know that within the SQL results, some of the utID values are NULL. After databinding to the GridView, I need to enumerate through the GridViewRows an read the DataKey values. However, when I try this I get the following error:
No default member found for type 'DBNull'. I am using the code below.
What object types are stored within DataKeys (I thought it was just integers or strings)
How to handle a NULL datakey value to prevent this error occurring?
I don't want to use Try Catch because it's too much of a 'hack'

View 2 RepliesI am making a website to store invoices so i can mail them to clients. So i got a table for clients, invoices and one with invoice products/services. When an invoice has no products/services added to them and it returns null i get the error "the null value cannot be assigned to a member with type System.Decimal which is a non-nullable value type."
I just started with linq. Before i always used mysql. Mostly i just had to call data from 1 table so forgive me if my linq query isn't really correct.
Dim invoices = From i In db.invoices _
Group Join p In db.products On i.id Equals p.invoiceId Into invoiceProducts = Group _
Select New With {i.client.naam, i.titel, (From iP In invoiceProducts Select iP.prijs).Sum}
i show the client's name, the title of the invoice and the total amount the clients will need to pay for products and services.

I need to generate a public string in C# that returns the machineGUID of the computer. This will be used to generate records showing who was the user and the computer who updated records.
View 3 RepliesSo I have this object I'm creating, just to hold some string and boolean data that I want to pass to the second page. So I have a class file:
[Code]....
[Code]....
And I'm setting values from form controls, like this:

So here is the really weird part: if I try to set a label's text property equal to objPrimaryScreeningData.myMemberVariable after selecting it - there is nothing there. I'm sure it's a stupid mistake - being self taught stinks.
I have a FormView that allows a user to register for a company event. I want to do a couple of things with this form.
1. I need to write this data to a MS SQL database
2. I need to send an email confirmation of their registration to their email.
I know how to do both of these things, but i am having trouble doing both at the same time.
It would be nice if I could do it in one click, but I coded it into two pages to try to help simplify it.
The first page allows the user to input their information into a formview and when they click the submit button, it places those answers into session variables:
[Code]....
[Code]....
The Second page confirms the users information by taking those session variables and placing them into labels:
[Code]....
[Code]....
However, after I place information into the formview on the first page, it throws up this error:
"Conversion from type 'TextBox' to type 'String' is not valid".
