I'm trying to understand when to use the type property and when to use the dbtype property. I looked online but couldn't find a good article that said when and why.

I had to format my hard disk and reinstall the Visual Studio 2005 Enterprise and SQL 2005 Standardprograms.
While my program worked perfectly before and still works ok on my second computer, I get the following error message on the formated computer:
Parser Error Message: Type 'System.Web.UI.WebControls.Parameter' does not have a public property named 'DbType'.
Source Error:
Line 82: <asp:Parameter Name="Olho" Type="String" />
Line 83: <asp:Parameter Name="image" Type="String" />
Line 84: <asp:Parameter DbType="Date" Name="inicio" />
Line 85: <asp:Parameter DbType="Date" Name="termino" />
Line 86: <asp:Parameter Name="pageId" Type="Int32" />
Source File: /0_oserigrafico/Default.aspx Line: 84
In this case I use a datasource control for a datalist and the parameter list is being built ba the system.
The DBType is created for the smalldatetime feild
how do I add the property named 'DbType'.
Traditionally with an Object Data Source, the wired up class will have its public properties available for binding (i.e. Gridview columns, etc.) which works well. But what if one of my wired up business objects has a property that is an object itself; can I drill down to a property on that object property and still use it?
So in additiona to the traditional:MyBusniessObject.OrderID...I want to use:MyBusniessObject.Customer.NameID
Your 1st response might be to just wire up the 'Customer' class, but I need properties both on 'MyBusinessObject'and 'Customer'. I do not think this can be done, as the ODS will not display properties on an object instance property. I have tried manually typing in the drilled down value as well, but that wasn't a success either.
I was looking at the options in Intellisense for the properties used with a parameter for the Object Data Source. There is one that I don't understand how it would be used. explain, or recommend an article, about the DB Type is for and how it would be used?
View 2 RepliesI have an insert that uses an object data source with out the direction property set and it works fine. I noticed the direction property though and wondered if I should use it.Should the direction property for the parameters of an object data source be used with a simple CRUD operations?

When I am passing Stored procedure parameter it expets 'System.Data.DbType" and the Data member is declared as a string.

I have an object data source that is being used by an rdlc report, and the object data source uses a filter that is built from session variables passed to the page.
The report displays correctly, with the filter applied; however, I want to mark each of the rows as "printed" in a bit field in the database table.
In the table adapter, I have the following Update command that is used by the object data source:
UPDATE dbo.WorkOrder
SET boolWorkOrderPrinted = 'True'
WHERE (WorkOrderID = @Original_WorkOrderID)
And in the Page Load event, I run:
ObjectDataSource1.Update();
However, no records are updated.
I created one stored procedure.

When my page is first loaded i receive error message stating to the effect
cant find Email for GetInvoicesByVendor.
this refers to a function in another class file:
Public Shared Function GetInvoicesByVendor(ByVal Email As String, ByVal vendorid As Integer) _
As IEnumerable
yet i only want to execute this function during the button click event and not when page is first loaded with the following parameters:
vendorid.Text = 1
txtcustomerid.Text = test@yahoo.co.uk

View 6 RepliesI'm using VS 2005 and SQL SERVER 2005,now i have a table with only two columns (their types: DateTime and SmallDateTime)
i key in some new records.Now I want to use GridView to retrieve that table, and use Calendar.SelectedDate as a parameter used in WHERE statement,I press "Test Query" and pop out a window "Parameter Values Editor",
here comes the problem.. how come the "DbType" is always 'Date'?After i click the list and select 'DateTime', but next time it will recover back to 'Date'I have to go to the source code find the "Dbtype" and change from "Date" to "DateTime" manually EVERYTIME~
Like This:
From:<SelectParameters>
<asp:ControlParameter ControlID="Calendar1" DbType="Date" Name="Date" PropertyName="SelectedDate" />
</SelectParameters>
To:<SelectParameters>
<asp:ControlParameter ControlID="Calendar1" DbType="DateTime" Name="Date" PropertyName="SelectedDate" />
</SelectParameters>
if i don't do this, it will lead to error:the version of sql server in use does not support datatype 'date'
It's weird that my original datatype is "DateTime" but the Dbtype is ALWAYS "Date" and lead to error everytime.
I wanted to delete the record from data but I receive this error "Unable to cast object of type 'System.Data.Linq.DataQuery`1[training_eval.Course]' to type 'training_eval.Course'.
Dim eval_sure = From ev In db.Evaluates Where ev.course_id = indexcourse Select ev.course_id

I am storing a custom "Organisation" object as a session variable. One of the properties of the Organisation object is "OrganisationID" (integer). I have a DataSource that requires a parameter value to run, and I want to use a SessionParameter to populate this. In a previous version, I stored the OrganisationID directly as a session variable. In that case, I could easily access it like this:
[Code]....
However, how do I now access the OrganisationID property of an "Organisation" type session variable (called "Organisation")? I have tried this, which does not seem to work: <asp:SessionParameter Name="OrganisationID" SessionField="Organisation.OrganisationID" Type="Int32" />

I'm an experienced PHP programmer that is new to ASP.net (C#). I'm trying to figure out how to do a manual echo of a specific field from an SQL database and was wondering how you do an if condition in case the field would meet certain criteria ?
What I want the script to do is check in the database if a certain condition is activated, then the html page should echo a windows media player object with the source of the video coming from the database itself ( $line[Video], and if the condition isn't active then either don't echo the player or just echo an old video (in the script I'm just printing a message).

I am using Visual Studio 2010 for the first time. I program in MS Access for a long time at decide to move to the ASP world. My problem is that I design my first web .aspx default page with a simple data grid. I decided to connect the data via the business object data adapter. I use the Dataset designer to great the dataset. All looks well and works fine on my PC. But when moved to the server I get the Terror "The type specified in the TypeName property of ObjectDataSource not found".
From my reading for the past two days, it seems that something need to be define (a class of some sort) to let ASP know where to find the data adapter. If this is the case, then why did not Visual Studio 2010 did not automatically build the class in the appropriate BIN/ APP_CODE or Global directory and more importantly, why would it work fine on the PC , but not on the server. I am totally blind-sided by Visual Studio 2010 allowing me to design and test on PC but throws me a curl ball with moving to a server. Am I assuming to much from Visual Studio 2010???
What is the solution.. What I am looking for is to know where exactly where and how to write this class. I am so new to ASP, all of my reading just confusing me more and more by reading so many post on this error. I know it is probably a simple class to write somewhere, but why did not Visual Studio 2010 write it accordingly.
I am trying to get an asp:SessionParameter of a SelectParameters, to use a property of an object in session
instead of having a string in the session like Session["CustomerID"]
Something like Session["Customer"] where the property is ((Customer) Session["Customer"]).CustomerID)
My code:
<asp:sqldatasource id="SqlDataSource1" runat="server" connectionstring="<%$ ConnectionStrings:DBConnectionString %>" xmlns:asp="#unknown"> SelectCommand="SELECT * FROM getStoreCustomers (@customerID,@week,@day)"
ProviderName="System.Data.SqlClient">
<selectparameters>
<asp:sessionparameter name="customerID" sessionfield="Customer" /> ?????? (what is the syntax to pass the property here?)
<asp:controlparameter controlid="ddWeek" defaultvalue="-1" name="week" propertyname="SelectedValue" /> <asp:controlparameter controlid="ddDay" defaultvalue="-1" name="day" propertyname="SelectedValue" /> </selectparameters>
The class I use is like any other class (but serializable)
[Serializable]
public class Customer
{
public int CustomerID
{
get;
set;
}
}
I'm trying to pass email addresses from an array to a stored procedure, then display the results in my gridview. I get the following error:No mapping exists from object type System.String[] to a known managed provider native type.On this line: Dim DR As SqlDataReader = MyCommand.ExecuteReader
