basically i have two dropdown boxes to filter data and textbox with stored procedure bound to gridview.i want to be able to query data depending on the selected value passed,either using one or more parameter values.
i would like seperate sqlcommands to chose from depending on which controls i select to pass parameters.
i have included a parameter Select(control id) as this is declared by the wizard for stored procedure.
but i am not sure how it is defined on the page and passed to procedure.

This would seem to be quite a trivial task, however I am having trouble retrieving the identity of the record inserted using the detailsview.insert() in the code behind. It would seem that detailsview.DataKey.Value would contain this value, but it is null after the insert is performed.

I tried to find a LINQ section on this forum, but couldn't, so I'll post this here since is deals with LINQ, C#, MVC, SQL Server, and well...just about everything.
Here's the details....My Application is an ASP .Net MVC 1.0 app, using C# 3.5, SQL Server 2005 Std, and LINQ to Entity.
In my View, I have numerous Html.CheckBox controls, they get passed to my Controller as a string collection via a JQuery Ajax call. The values of each checkbox are seperated by a comma(,). I then Split the string, to get the individual values. The overall purpose to to allow users to build a custom report with only the data elements they have checked the boxes for. Here is my controller:
[Code]....
The part that I am having a problem with is that I only want to Insert the data elements into my DB table for the ones that the user has selected the checkbox for. So, for example, I'd like to do something like this:
[Code]....
I don't know if there is a LINQ switch statement in which I can access outside variables and the columns of the table, or any thing like that.

I want to be able to show the record that was just inserted after add_button_click event. I run the insert from mycommand and then set mycommand2 to run the read to populate a details view. I have a feeling I am going about this the wrong way. The insert fires correctly but the details view does not populate.

I have a page (i.e. page1.aspx) that a user will select from the record and it will press on the delete button. And it will redirect on another page (i.e. page2.aspx). On page2.aspx, I wrote my query for example
Code:
DELETE FROM items WHERE item_id=2 how may I know if the query was successfully processed because I have to redirect again on the first page.

Trying to check if an insert of a new record into an SQL table is happening successfully. I can see that the insert is occuring OK but am not getting the verification to happen.
I'm a little new to C#, I'm thinking it may be in the syntax I'm using in my method in the .cs file line 45. Can't seem to fix it right though.

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
My objectdatasource is declared as follows:
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"

i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?
