Method Invoked When A Gridview Records From Database Are Null
Apr 3, 2011
I have a gridview which uses a stored procedure with session["UserName"] as a parameter to retrieve the records from the database.
Here is the code for that gridview Sqldatasource:
[code]....
lets say a particular user who has logged in doesn't have any records in that table on which this particular stored procedure is being executed. Then there won't be any records associated with gridview. So in this scenario: is there any method that gets executed or some exception is thrown, so that i can explicitly use that method/exception/property to display a message Label to the user like "No records to show !!"

I have many webmethods in one asmx. I need to perform licence checking before some of this webmethods invoked. I can insert following code to each web method that needs checking:
if (!AllRight())
{
// badRequest
return;
}
Or I can insert complex filter to HttpModule to detect webmethod by URL. I need something like attribute for webmethod and place where I can handle it. Is there pretty good solution?

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.

The website is over half way done and the functionality for the blog is (except for adding posts) is already implemented and working correctlyI have a SQLExpress 2008 backendBlog posts are rendered on the page with full HTML markup within a label control.
All of the above is done and working. Though I am essentially new to creating websites with ASP.NET, CSS and SQL, I am sure that I could simply carry on and make a login page with some controls that would allow me to add records (blog posts) directly to the database on the host server. However, I am fearful of doing this because I know that malicious code can be passed in this way. Also, because of my lack of knowledge, the only way that I know of to pass the code from a control to the database is to disable validation for the page the control is on. Without a doubt I do not want to do that.
So what are my options for getting blog posts into the database? Is it safest for me to fully create the post in html and update a copy of the database that resides on my local machine? If I do it this way, how can I merge the records from the database on the local machine with the records on the remote server?

I am using VS 2008 SP1. My also have included CSS Friendly adapter [URL] in my project ( I mentioned this because my GridView Empty data template is not showing when using GridView's CCS Friendly adapter). I have a GridView and a DetailsView. When a record in GridView is selected its details information is shown in the Details View. Type of Data source I am using is ObjectDataSource. My Insert and Update methods works perfectly. It is only the Delete method that is passing null values to the underlying object delete method. My source codes for both the UI, BLL, DAL is shown below

lblMsg.Text = "Records Existed"
End If
but there are error message. "Object variable or With block variable not set."

I'm trying to bind a nullable bit column, which at the moment is mostly null, but I need to somehow convert the null to a 'false' on runtime because it doesn't bind to a checkbox if it's null. But, I am currently unable to change the default value and update all records accordingly - is there a way to do this in runtime?

I'm developing a website with ASP.NET MVC, NHibernate and Fluent NHibernate and want to know how can I customize my Map to get records using a custom Method.
My entities:
public class ImageGallery {
public virtual int Id { get; set; }
public virtual string Titulo { get; set; }
public virtual IList<Image> Images { get; set; }
ublic virtual bool IsActive { get; set; }
}
public class Image {
public virtual int Id { get; set; }
public virtual ImageGallery ImageGallery { get; set; }
public virtual string Low { get; set; }
public virtual bool IsActive { get; set; }
}
My Fluent NHibernate Maps:
public class ImageGalleryMap:ClassMap<ImageGallery> {
public ImageGalleryMap() {
Id(x => x.Id);
Map(x => x.Titulo);
HasMany(x => x.Images)
.KeyColumn("ImageGalleryID");
Map(x => x.IsActive);
}
}
public class ImageMap:ClassMap<Image> {
public ImageMap() {
Id(x => x.Id);
References(x => x.ImageGallery);
Map(x => x.Low);
Map(x => x.IsActive);
}
}
And, a method on my ImageRepository class:
public IList<Image> ListActive() {
return this.Session.CreateCriteria<Image>()
.Add(Restrictions.Eq("IsActive", true))
.List<Image>();
}
If I create an object this way:
ImageGallery ig = new ImageGallery();
I can access my the Image's list using:
foreach(Image img in ig.Images) {
...
}
However, ig.Images give me access to all images records and I would like to access just active records (or another criteria), using ListActive()'s repository methods.

Using a ListBox, where multiple items can be selected. Using StringSplit SQL function the string passed from Listbox is separated where the delimeter is comma ( , ).ListBox is in search form where user enters search criteria using other controls and the ListBox. All works good by simply using below SQL statement in Stored procedure that carries search.

Question:- Now one of List Item is None , when None is selected or None is selected with other ListItems from ListBox it is required to retrieve all records where COLUMN IS NULL.Example: When the Male, Female and None is selected from ListBox, SQL statement in Stored procedure will be
[Code]....
Like to know how this can be handled? It is required to retrive NULL values when None is selected in ListBox as well as in combination of other ListItems(Male and Female) i.e., Male, Female, Null when user selects multiple items from ListBox.

i have a dataTable, which contains a column which has 100 rows, now i want to add those rows in ArrayList, but not with the Add Method, because i have to use for loop for adding records one by one, so i want to prefer addrange method of arraylist, so it is possible to add records in arraylist from DataTable using AddRange.
Below is the code which i am using.
Dim adapGetImages As New SqlDataAdapter("select distinct FileName from Files where Filename<>'' and (RIGHT(FileName,3) = 'gif' or RIGHT(FileName,3) = 'jpg' or RIGHT(FileName,3) = 'bmp') order by FileName", connection)
Dim dtGetImages As New DataTable()
adapGetImages.Fill(dtGetImages)
ArrayList1.AddRange(dtGetImages.Rows[0][0].ToString())
The last line is where i am stuck. as if i run this it will just add single row, and if i say dtGetImages.Rows.ToString() then this will just Add System.DataRow in Arraylist and not its content.
