Basically, the user Selects a row on GV that executes an Insert into a table the GV cell values of the selected row.
The SQL field data type is varchar. If the GV field is Null, the Insert adds the value to the SQL field. How do I keep the @nbsp; from being displayed in the cell of a data control when it is called at a later time? Do I add some more asp to my control parameter? do I add some vb code behind? Here are some relevant code snippets of existing code.

I have got a problem about setting the optional parameter to NULL in sql sp. Initially I set all the parameters null in the sql sp. That's OK. But I would like to set the parameters to Null again if a particular parameter has a value of - 1 by using the "IF ELSE" statement block. However, the problem was that I was unable to set the parameter to NULL in the IF ELSE statement. So please correct my IF ELSE statement in the store procedure. This is really urgent and important for my project.

i am inserting the value of dynamic controls into the db like so;
Dim ae1 As DropDownList = FindControl("AreasExpertise1")
If (ae1 IsNot Nothing) Then
x.Parameters.AddWithValue("@areasexpertise1", ae1.SelectedValue)
End If
then in my query i have parameters like so;
INSERT INTO [foo] ([etc], [etc], [etc], [areasexpertise1], [areasexpertise2])
VALUES (@etc, @etc, @etc, @areasexpertise1, @areasexpertise2)
When the user fills out the form, they see only areasexpertise1 and have to press a button to dynamically insert another area of expertise...If they only have 1 area of expertise, the query crashes and says 'must declare variable @areasexpertise2.Please can you tell me a way to either insert nulls when the parameters are empty, or to ignore them?

View 5 RepliesI'm using a custom route to create the following URL (http://mysite/subscriber/12345) where 12345 is the subscriber number. I want it to run the ShowAll action in the Subscriber controller. My route is firing and using Phil's route debugger, when I pass in the above url, the route debugger shows ID as 12345.
My controller is accepting an int as subscriberID. When it fires, the controller throws the error "The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32". Why does the route debugger show a value and the controller doesn't see it?
Here's my route (first one is the culprit)
routes.MapRoute(
"SubscriberAll",
"subscriber/{id}",
new { controller = "Subscriber", action = "ShowAll", id=0 },
new { id = @"d+" } //confirm numeric
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
I'm getting a null in the ShowAll action? Here is the action method signature:
public ActionResult ShowAll(int id)
How to check the query string value null, if null then display the default value instead of object reference error.
