CheckBoxList's Datasource is null

Posted By:      Posted Date: September 13, 2010    Points: 0   Category :ASP.Net
Hi, I am trying to get solution for below problem. Please help.Page 1: To add a record in to DB. At this page, as per the user requests , few controls will be added to the page from server side code.one of them is checkbox list.and when user is requesting to save data, its going to the DB.Everything is fine upto now.Page 2: To edit the record which is entered from page no 1. When user requests to edit the record entered at page no 1, i'm redirecting user to this update page, with record id, and generating the required controls to show the values.Now the main problem is :When page is loading first time , I m creating the required controls and then assigning the values to them to edit.but after that at each postback, the value of datasource of checkboxlist is becoming null, same case is with the label control.but the value of textbox is same, it is not becoming empty at each postback.In code :   In code i have created two method to generate controls.1st is : to create new controls, and to assign values to them2nd is : to regenerate the controls at each postback, with the same IDs, but not assigning any value here.I think viewstate will reload the values of respective controls, if IDs are same.So , what should  i do here?

Hide a repeater in ASP.NET C# if the DataSource contains no items?

I have an ASP.NET page that uses a repeater nested within another repeater to generate a listing of data. It's to the effect of the following:
In the (C#) code-behind I'm basically using LINQ to pull a listing of information from an XML document and bind that information to the first repeater.

Searching for the answer to this, it seems the method is to determine whether the data for the nested repeater is empty. If it is, then you set the visibility of the repeater to false.

Manually sorting and paging Gridview without using datasource control

Many a times while working with Gridview we want to work with the paging and sorting functionality without using any datasource control. Gridview is flexible enough to perform these tasks without the use of any datasource control and only a few lines of code.

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?

Dynamic Data, Domain datasource, Poco and lookups


Mr. Edward,

Excuse my question but: it is necessary to involve in our projects something more than just Dynamic Data or should we make use of all other features available in VS2010 (which will make assume taht they had been left out of the Dynamic Data framework) like: wef, poco, azure, wcf, cloud, mvc, silverllight, ajax, odata, agile, workflow, etc.?

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

Search for a string in my datasource dynamically


I am displaying an Rssfeed on my page by using XmlDataSource and Datalist controls.

I want the user to be able to limit the information that is returned to my datalist.  To do this I have a textbox on the form that allows the user to enter their search criteria.

I need to be able to dynamically create a query string utilizing the information that the user entered in the textbox.  I am also using a drop down list and allowing the user to select whether they want to search in the title, description, or all parts of the xml file.

I am having trouble figuring out how to reference the data contained in my textbox in my query string.  Where the query string says 'asp', I want to replace 'asp' with the content from my sSearch variable.  Can anyone tell me how to reference my variable in the query string???

string sSearch = txtSearch.Text;
        string SQuery = "";

        if (DropDownList2.SelectedIndex == 0)
            SQuery = "[contains(title), 'asp')]";

'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'](
                function() {
                    return element.className;
                function(newValue) {
                    element.className = newValue;

Using SqlDataSource as the Datasource to Accordion



The accordion does not renders. What am I missing? I want to use a parent child kind of accordion. Perhaps the child is not defined correctly, but I would like to see at list the seven tabs with the name of each organ system show up. The numbers of records for each organ system varies and I need a text box for each organ/tissue to be displayed, so I can insert in a findings table.

Here is what I have

new protected void Page_Load(object sender, EventArgs e)
            ModalPanel.Visible = false;
            ds1 = GetSqlOrganSystems();

protected SqlDataSource GetSqlOrganSystems()

         SqlDataSource dsL = new SqlDataSource();

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;
