Is it possible for a Controller Base class to access a parameter from an action link and if so how do I access that parameter within my Base Controller?
Action Link:
<%=Url.Action("Area_1419", "Home", new { SectionId = 1})%>
Base Controller Class:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Website.Models;
namespace Website.Controllers
{
public abstract class CategoriesController : Controller
{
public CategoriesDataContext _dataContext = new CategoriesDataContext();
public CategoriesDataContext DataContext
{
get { return _dataContext; }
}
public void SectionID()
{
int SectionID = Convert.ToInt32(Request.QueryString["SectionID"]);
ViewData["SectionID"] = SectionID;
}
public CategoriesController2()
{
//ViewData["Categories"] = from m in _dataContext.Categories where m.Area_ID == SectionID select m;
//ViewData["Categories"] = from c in DataContext.Categories select c;
}
}

I have created a DataSet which is connected to an Access Database. This DataSet is linked to a report and I would like to apply a filter to only display information relevant to the logged in user. My question is, if I wanted to add a parameter to the filter in my DataSet, what is the correct syntax when entering parameters? Whatever I try, it seems to convert automatically to a string.

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" />

Is it possible to change a parameter's property after the uer has made a selection or filled in another parameter field? I'm using VS2005
Case:
- 3 parameter fields; Country,Station,Carrier all three are textfields and are allowed to stay 'blank'.
- When the user enters a Country-code in the 'Country' parameter field, the 'Carrier' parameter should become a required field.
I did some searching on the net, but haven't found the solution. I started to wonder if it's actually possible?

On selection of option 1 , a country parameter should be enabled with all countries' values defaulted.
Option 2 should enable Region parameter with all the Regions values selected and country parameter should be displayed.
Option 3 should disable both Region & Country Parameter.
I am using SSRS 2005 with Enesys tool as add on.

One of our customers has a report with a single value string parameter that has over 1000+ possible values. selecting single value from 1000+ choices results in bad UI, among other things.create another parameter that acts a filter for the other parameter. So you would have Param1 with say 25 choices and selecting a choice would narrow down the option for the second parameter.Is this the best way. What is the best practice for handling these kinds of parameters?

How do you use the http POST method with a Grid View on another page. I am trying to use the POST method to send the ID from the selected row of a Grid View, I am using a link button set to fire the select command and it has the Post Back URL set, from one page and then retrieve the ID value on another page using an Object Data Source. Also, under the Defining Parameters, I am setting the ID parameter to Form Parameter Source and have entered the Grid Views name in the Form Field.

Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.

Here's a short explanation of my asp.net project.
1) the default page loads, it will read the Windows Login of the user opening the page.
2) I'll check if this login exists in a table stored on the webserver.
In this Access Database, there's a 2nd linked table, pointing to another access table on a network location. Now, I want to read data from this linked table. However, at this moment I receive an error:
"The Microsoft Jet database engine cannot open the file '\<ip><shared-folder>statistics.mdb'. It is already opened exclusively by another user, or you need permission to view its data".
Some extra info:
- The network folder has read and write permissions for everyone
- the user and group permissions on both access files are set to read/modify/administer for the Admin user (on the tables I want to read from)
- IIS authentication on the server is set to "Windows Authentication" (this is needed so I can read the Windows Login from the user). All other authentication modes are disables (like anonymous, ...)
- When the error occurs, no other program or process has access to the statistics.mdb (so, it can't be locked by someone else)
- the web.config files access connection string looks like:
<add name="AccessConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\<IP><shared-folder>statistics.mdb;User Id=admin; Password=;" />
Like I said before, in this statistics.mdb file, there are 2 tables. One normal table, and another linked table (pointing to a network location)
Searching for solutions, I discovered the following:
- if I don't use linked tables, everything works fine (however, I have to use this linked table)
- even if I connect directly to the table in the network I receive the error. So, I'm pretty sure I don't have sufficient rights to read from this table.
I read that not the Admin user is opening the file, but actually a user called ASP.NET. This user doesn't have the correct rights to do this. However, I'm not sure if this is true.

We're getting a server error saying "Parameter count does not match Parameter Value count." Anyone have any idea what this could mean?
[URL]
Our site's on ASP.NET Webforms running DotNetNuke as a CMS.
I've tried uploading an older version of the web.config file but it doesn't seem to have changed since the error came up. It wasn't in any of our recent module file uploads because I reuploaded the old files from this morning that we changed.
Could any changes in the database cause this or would it have to originate from an error in the code?

I have to display data (names) in a random order on the website. The data is stored in a MS Access database. The names must be displayed in a GridView and DataList in different places. I have created a query in MS Access "zorder: Rnd([MarinaAccommodation]![ID])" which works fine in MS Access giving me a different order each time.
The problem is that when I try run it on the website the order remains the same, it does not change each time the page is loaded.

I have a situation where I am accessing a database multiple times and I'm wondering if it is necessary.
I have a GridView with a template column with a hyperlink to "Get Results" and on the RowDataBound event I have it check the batch number against the database and see if results exist and then if they don't, hide the link.
So when viewing the page if there is 20 rows in the gridview it is effectively doing 20 queries.
I was wondering if it is a better idea to query the database once with all "batches" and load it into a datatable, then on the RowDataBound event query the datatable. The only issue I see with this is there is currently 40,000 batches and grows daily.
