hiding hyperlink in url when its navigateurl is null

Posted By:      Posted Date: September 02, 2010    Points: 0   Category :ASP.Net
Hi Friends, I have a hyperlink control on my datalist. The navigate url property is bound to a field called "AttachFile" in my datatable. Is there a way I can make the hyperlink control invisible if the field it's bound to is null or blank? Thanks in Advance, Sepid

How to check for null/empty strings on dynamic objects?


What is the proper way to check for null or empty strings on dynamic objects? This is the only solution I've found so far:

if (admin.PasswordHash.GetType() == typeof(DBNull) || admin.PasswordHash == string.Empty)

If the field is null, the object returned is DBNull.Value, but if the field is empty string, it's return as a System.String object. This makes it impossible to do regular "admin.PasswordHash == DBNull.Value" check, as that will fail whenever the field has been set to empty string. Is my example the right (and only) way to go?

Users getting logged out because HttpContext.Current is null


We've  been trying to fix this one for a couple years, and I'm just out of ideas, so any help is really appreciated!

We've got a fairly large, complex web application that uses Forms Authentication to authenticate users.  Throughout the application we store and retrieve information about users in the Session object, and in some cases in cookies.  In a couple places we check for the existence of the context, and if it's null we send the user back to the login page to re-establish the session. 

Just a quick run-down of this web app: C#, .NET 3.5, IIS 6, ASP.NET State Service to manage session

As for the session timer, we use our own home-grown timer, which is basically a client-side timer, which is backed up by a check to the SQL database to see when their last activity was.  This seems to work well for us.  It's not perfect, but it allows us to notify the user before the session times out, and allows us to be certain we're not logging a user out before their 60 minutes of inactivity is up.

What's happening is that certain users are being logged out after just a few minutes.  We've eliminated the timer as a cause and believe what's happening is the HttpContext.Current is null, so the user is logged out.  We do not know why the HttpContext.Current is null, and I underst

Restrict Hyperlink

'element.className' is null or not an object



I just downloaded the project, compiled it and ran it right out of the box and when I put the mouse pointer over or remove the mouse pointer from either MenuItem in the menu demo, I generate this error:

'element.className' is null or not an object

It points to this javascript method:

updateClassName: function(operation, element, name, value) {
        this[operation + 'String'](

How to deal with NULL values in a SQL table


 Hi all

In order to add/update/delete data from a table I build 2 classes: 1 class containing all the table fields and another class with methods to add/insert/update/delete records. I am learning how to avoid errors when your table must use SQL NULL values. One error is when I call my UPDATE method (see below):

  public void UpdateItem(OcItemConstraintDetails item)
  SqlConnection con = new SqlConnection(connectionString);
  SqlCommand cmd = new SqlCommand("ItemConstraints_Update", con);
  cmd.CommandType = CommandType.StoredProcedure;

  cmd.Parameters.Add(new SqlParameter("@itemConstraintId", SqlDbType.Int, 4));
  cmd.Parameters["@itemConstraintId"].Value = item.ItemConstraintId;

  cmd.Parameters.Add(new SqlParameter("@path", SqlDbType.NVarChar, 150));
  cmd.Parameters["@path"].Value = item.Path;

if you watch the SQL profiler trace you will see that I am passing a value of 'default' ;so that causes me problems.

exec ItemConstraints_Update @itemConstraintId=1,@path=default

With that said, what are the best practices when your SQL table accepts NULL values and when:
- you are passing an empty value to your stored procedure;

error in MicrosoftAjax.js: Cannot read property '_notified' of null


I am cross testing my project with multiple browsers: IE7, Firefox and Chrome.

One one page I have a dynamically built table with two DropDownLists and CascadingDropDown extenders. Maybe the only thing special about the drop down lists is, that I add a "onChange" for the second drop down list in each row which shows or hides the list depending on the value populated from the web services.

All of this works perfectly in IE7 and Firefox, but Chrome does not execute the JavaScript in the onChange attribute and the error console says:

Uncaught TypeError: Cannot read property '_notified' of null

Linq to SQL returns null for DateTime fields.


I have a linq to sql entity class in which I declared some DateTime fileds like this:

[Column(DbType = "smalldatetime")]
public DateTime? StartDate { get; set; }

And this is how I fetch data form repository:

return repository.Logs.OrderByDescending(l => l.LogID).FirstOrDefault();

All non DateTime fields are filled properly but all datetimes are null.

[Column(DbType = "smalldatetime")]

        public DateTime? StartDate { get; set; }
