Operator '=' is not defined for type 'DBNull' and string "REJECTED".

Posted By:      Posted Date: October 08, 2010    Points: 0   Category :ASP.Net


I know that the problem is my field having NULL values. However, I don't know how to have it process the code even if the field have nulls

here's my code:

 Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound

        If e.Row.RowType = DataControlRowType.DataRow Then
            Select Case DataBinder.Eval(e.Row.DataItem, "userStatus")
                Case "REJECTED"
                    e.Row.ForeColor = Drawing.Color.Red
                    e.Row.Font.Bold = True
                Case "ACCEPTED"
                    e.Row.ForeColor = Drawing.Color.Green
                Case Is = vbNullString
                    e.Row.ForeColor = Drawing.Color.Red
            End Select
            Select Case DataBinder.Eval(e.Row.DataItem, "Status")
                Case "Editing"
                    ' e.Row.Font.Bold = True
                    e.Row.Cells(6).ForeColor = Drawing.Color.DarkOrange
                Case "Active"
                    ' e.Row.Font.Bold = True
                    e.Row.Cells(6).ForeColor = Drawing.Color.DodgerBlue
            End Select
        End If
    End Sub

Unable to cast object of type 'System.DBNull' to type 'System.String'.


 I saw lots of post about this issue. but haven't got good solution for that yet. Basically, what I did is that: I have a table in SQL database and some of data fields allow null. I built Objectdatasource through dataset. When I built update page using dataset. It generate the following error before showing the update page correctly. It seems I have issue to retrieve the null value from the database through using objectdatasource through dataset. Any suggestions?

How do I handle Conversion from type 'DBNull' to type 'String' is not valid

The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must



This is frustrating, and I don't know how to solve it.

I have a strange problem. I am adding a LinqDatasource object, and set the context:

        protected void LinqDataSource_ContextCreating(object sender, LinqDataSourceContextEventArgs e)
            e.ObjectInstance = new KaruselaDataContext(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

Then I get this error:
The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'.


On web.config I already have this:
<add assembly="System.Data.Linq, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

NOTE: The datacontext is in a different project (DLL proect) where I added a refernce to System.Data.Linq.

is there another way adding a refernce to a web project? or only though teh web.config?


"Type ASP.x is not defined" error for dynamic user control when publishing updateable


I have a user control (ContainerCtrl) which programmatically instantiates another user control (SimpleCtrl) in OnLoad. It builds and runs fine, but when I publish it I get the error "error BC30002: Type 'ASP.SimpleCtrl' is not defined." (If I publish without the "updateable" option there's no error, but I need the site to be updateable.)

I assume this has to do with the particulars of how the assembly(ies) are built for the different compiler options. My question is, how can I get it to work properly for "updateable" publishing?

VS 2008 / .NET 3.5 sp1

The code follows (web.config is the default from Visual Studio).

Many thanks, Dave

Conversion from string to type 'Date' is not valid



Im receiving a strange error Error Message: Conversion from string "15/08/2010 22:21:35" to type 'Date' is not valid.

I know this is generally down to cultural date formats etc, however the reason this is strange is it just randomly occured twice in the last week, the website has been running since october and nothing has changed,

The error constantly occured until the IIS was reset and recompilled the site, its been running fine since, however im just trying to figure out what could cause such an error to occur.

I've narrowed it down to a line of code which is:

bktime = DReader.Item("Bktime").ToString

bktime = Year(CDate(bktime)) & "-" & fmt(Month(CDate(bktime)), 2) & "-" & fmt(Day(CDate(bktime)), 2)

Has anyone else encountered this randomly occuring and is there anything i can put in place to prevent this in future?



Creating a table-valued function on a user defined type in SQL Server CLR

We would like to be able to create a table-valued function on a user defined type.  We would like the syntax in SQL to look like it works for the XML nodes function:   DECLARE @myXml XML = '<a><b>1</b><b>2</b><b>3</b></a>' ; SELECT  node.query('text()') FROM    @myXml.nodes('a/b') nodes (node) ;   In other words, in the FROM clause, we can access the "nodes" method of the xml variable and it returns a rowset. Thanks!

Java - Type not defined error with ReportViewerWebControl.axd

I've been searching for several days now looking for threads / solutions in regards to a Report Viewer Problem. OS - Windows Server 2008 all updates installed DN FW - 3.5SP1 and 4.0 ReportViewer.exe was and is installed (Version 10.0.30319.1) The ReportViewer Assemblies are in the GAC The project is a Visual Studio 2010 project The application is running in it's own App Pool with the 4.0 framework in integrated mode In order to pin this down I have reduced a test project to an empty page with a Report Viewer Control and a Button. There is no DataSource and no report associated with the viewer, just the empty viewer control. The web application runs without errors on my dev box and on a new test environment (with the Web Server in a VM) that I set up to test with. When I deploy to our test or staging servers the page fails with Java Script errors. The error that is the root cause is "Type is undefined" which is referring to Reserved.ReportViewerWebControl.axd.  When using the developer tools for IE the script is loaded but fails at Line 1 of the script Type.registerNamespace("Microsoft.Reporting.WebFormsClient"); with the message Type is undefined.   'Type' ist undefiniert  Reserved.ReportViewerWebControl.axd?OpType=Resource&Version=10.0.30319.1&Name=ViewerScript, Zeile 1 Zeichen 1 When I call the ReportViewerWebCont

Conversion from type 'TextBox' to type 'String' is not valid

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:Protected Sub InsertButton_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Session("FirstName") = Me.FormView1.FindControl("FirstName") Session("LastName") = Me.FormView1.FindControl("LastName")  <li> <label> First Name</label> <asp:TextBox ID="FirstName" runat="server" class="text-box" Text='<%# Bind("FirstName") %>' /> </li> </ul> </div>
