At this point, my intention is to have table1 containing a list of Table2 and anotherTable1 containing 0 Table2. However, both table1.Table2 and anotherTable1.Table2 become 0 count.

I am building an ASP.NET application that needs dynamic tables. That's another issue that I've already posted about (and gotten a pretty good response!). Now, I'm running into another issue - I want to add new rows to my table, but given that I will have 10-12 tables on one page, each containing different objects in their rows (text boxes, check boxes, etc.) I need a way of simply generically adding a new row that has the same objects as the first row in the table. Here's my code:
Private Sub AddTableRow(ByRef originalTable As System.Web.UI.WebControls.Table)
Dim originalRow As System.Web.UI.WebControls.TableRow = originalTable.Rows(1)
Dim insertingRow As New System.Web.UI.WebControls.TableRow
Dim insertingCells(originalRow.Cells.Count) As System.Web.UI.WebControls.TableCell
Dim index As Integer = 0

I have a cached control object form a UserControl in asp.net cache. I like to access my control and make a copy of it to freely change it without having any affect on the base cached control.
View 2 Replieshow to take clone of an Input Stream. I want to take clone of file uploaded through file upload control. ie clone of fileUpload1.PostedFile.InputStream;
View 1 RepliesI would like to serialize the properties of the HttpBrowserCapibilities object so that it may be returned via a web method call. Currently the object cannot be serialized:Cannot serialize member System.Web.Configuration.HttpCapabilitiesBase.Capabilities of type System.Collections.IDictionary, because it implements IDictionary. ...which is understandable. However, I would like to simply copy out the properties and their values to a hierarchy, i.e.
<HttpBrowserCapabilities>
<IsMobile>true</IsMobile>
</HttpBrowserCapabilities>
I'm starting to think I would need to use reflection to copy this object, but I haven't reached a conclusion. Does anyone have any suggestions to keep this simple?
Is there a simple solution for duplicating table rows in SQL Server as well as all table rows with foreign keys pointing to the cloned table row? I've got a "master" table and a bunch of "child" tables which have a foreign key into the ID of the master table. I need to not only create a perfect copy of the master table, but clone each and every child table referencing the master table. Is there a simpler way to do this than creating a new row in the master table, copying in the information from the row to be cloned, then going through each child table and doing the same with each row pointing to the cloned row in the master table?
I'm using a SQL Server 2005 Database accessed through C# ASP.net MVC 1.0.
I have a Clone Client feature that allows a user to select a current client, and click submit, and then several fields of data are copied from the selected client, and saved in the sqldb via a stored procedures under a new client number. (Makes it easy for users to add new clients, when client data is similiar)
The problem I run into is when the selected client has multiple rows of data for a field such as the email field. If the client to be cloned has 5 emails in another table named tClientEmails, I need to insert all 5 emails for the new cloned client in tClientEmails. How do I tell SQL to loop thru and insert all 5 rows. Here's my code so far which copies all the data except the email field. Just don't understand how to insert all the emails for the client that are returned. The inserting of the emails has to happen AFTER my sql below, because the new ClientID is returned as an identity parameter.

I am confused about how to reference objects in session, how to update, and copy.
if I create
MyObject obj = new Object ();
then
Session["object"] = obj;
MyObject temp = (MyObject)Session["object"];
If i change something on temp, will the object in session be updated? do i need to follow changes with Session["object"] = temp?
i am using sql express 08 & sql management studio exp 08. I tried to clone a database from another but an error occured. My steps:
[newDatabase] >> right click >> tasks >> restore >> databaseOn general section: from database = [databaseSource] >> backup sets: all checked
On options section: overwrite existing database: checked, recovery state: restore with recoveryClick [ OK ] button The error:
Restore failed for 'MyServerSQLEXPRESS'. (Microsoft.SqlServer.SmoExtended)
Additional information:
System.Data.SqlClient.SqlError: The file 'x:.........databaseSource.mdf' cannot be overwritten. It is being used by database 'databaseSource'. (Microsoft.SqlServer.Smo)
And why sql management studio tried to overwrite the dataSource (not newDatabase)? how to clone a database? I also tried backup databaseSource to file and then restore newDatabase from the file but resulting the same error.

What would you recommend me to do in order to accomplish that?I'm developing a Scheduling software and i love google's interface (view in day, week, month) but i'm thinking in doing everything from ground zero. Is there a way to use pre-created controls or something much more easy than my idea ?

View 5 RepliesIn the VS2005 environment, when I test my session to make sure the page redirects to the main page (itself) if the session is null, it works. There is no error.
The function I use for this is:
[code]....
However, when it is in the production environment in IIS 6.0, when the session has timed out, and I then do a postback by doing some slider control, I see the page reload but immediately thereafter, it throws a Server Error exception of : Object reference not set to an instance of object.
Looking at the stack trace, the event occured:
AJAXEnabledWebApplication1._Default.Slider1_TextChanged(Object sender, EventArgs e)
however, why is it that the Slider1_TextChanged event fired even even after during page_load, the page was told to do a response.direct ?? shouldn't the entire page have gone through a full-page refresh life cycle ? why did it continue on to attempt to raise the Slider1_TextChanged event?
can you please help me to brainstorm the possible causes of this error. I've got a paged repeater with localisation bound programitcally to an sqldatasource using a stored proc. I can post code if needs be but it's rather long. I'm looking for typical causes of this error + will make note for future reference!

If I run that code everything works out fine. The page loads and all is well. But, if I try to do the same thing to a page that uses my MasterPage.master file, I get the following error:
Object reference not set to an instance of an object.
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Why is that? In the example code from the book (that also uses a MasterPage.master file), everything excutes and runs just fine. But in my test, I get the above error. I've tried comparing my pages to the books included source pages, but I can't find any differences.
In the same Code behind file I have:
// This works
Label lblTopNavBarInfo = (Label)Master.FindControl("lblTopNavBarInfo");
lblTopNavBarInfo.Text = "Currently Serving: + FirstName + " " + LastName ;
// This compiles but throws an error in the browser
LinkButton lnkBtnProductsOwned = (LinkButton)LeftNav_CustServ1.FindControl("ProductsOwned"); // The Control is visible
lnkBtnProductsOwned.Enabled = false; // Error: Object reference not set to an instance of an object.
I have a website written in C# that was running fine on one server. We moved it to another server and have a couple issues. I am mainly a VB.NET coder but can do a few things in C#. This is not a project - it is a website and can open it in VS2008 no problem. This is an admin site for the whole website where the user can add customer comments, etc. When logging in, it works fine. I can go to one of the admin pages after logging in and works. If I go to two other different pages, I get this error:
Object reference not set to an instance of an object.
[Code]....
It turns out this is in the main.master page and it is used by the other pages that load fine. The ApplicationTitle variable is set right in the web.config file and like I said, it shows on the other pages.
My question is why would this code work fine for some pages and not two others? All of these admin pages are under a folder called Admin and the web.config file is in the root folder of the website. Its almost like these two pages cannot see the web.config file in the root folder? Why would that be if thats the case?

My guess is that the source of the problem could be in the foreach loop from my cart class, shouldn't I be using that for arrays only? If I need to post any markup code or any other class, let me know.

Again, I am new to the ASP.NET world, and I come from a Windows Forms background. I'm working with an ObjectDataSource that retrieves a collection of business objects. With the collection, I am going to be binding it to a CheckBoxList and other various controls. The business object that I am using is an Employee.
To get all of the employees, I create an ObjectDataSource and set the "Select" method. I then set the DataSourceID of the CheckBoxList to be that of the ObjectDataSource. When I load the page for the first time, I see all of the employees. Now, the user goes through this page and selects all the employees they want to see information about (by checking the box next to the employee name). Finally, the user hits the button called "Display." Upon postback how do I get a list of those employees? I've tried the following solution, but I'm not sure if it's the best practice in obtaining all those employees again. Here's my solution...
In the CheckBoxList, I set the DataTextField to the Employee's name. I also set the CheckBoxList's DataValueField. This property is a little different. I set this to be a UNIQUE IDENTIFIER, which can distinguish this employee from other employees. Now, when the user hits the button "Display" I use my ObjectDataSource again and MANUALLY call ObjectDataSource.Select(). I cast the returned value as a List<Employee>. Finally, I iterate through all list items in the CheckBoxList...
[Code]....
If the item is selected, I parse through my list of employees that was returned from the bjectDataSource.Select(). I use the item.Value and compare it to each employee's "key." If the key is found, I know that the employee is selected. I put this employee in another list called EmployeesSelected.
Finally, I take EmployeesSelected (which is a List) and set my GridView's .DataSource and call .DataBind() on the GridView.
Is this the "best practice" of re-obtaining the Employees that are selected on my page, or am I making this too complicated?
