I am trying to stop the data flow when certain conditions happen in the script component. Like if a row in the data set has an invalid date, I dont want that dataset to be inserted in the tables or go through OLEDB Destination, rather I want the entire data flow for that dataset to stop and go back to the control flow page.
I have tried mulitple solutions but nothing worked. Conditional Split ends up inserting the correct rows, but I just dont want anyting to be inserted when one row is bad, where as I do want the entire dataset to be inserted if all rows are good.
How can I fail the component when certain conditions happen int eh script component.

I am developing a call center application. The way it works is it read records from a database and from these it creates dynamic questions and either textbox or dropdown controls on one of about 5 tabs. The questions can change depending on the previous answers, thats why they need tgo be dynamic. The issue is the postback will loose the controls I have created. I thought about maybe just keeping a hashtable of the controls in the session and then recreating them each page create. The trouble is the page flicker. what the best way to handle this ??? I've though about update panel manipulation but nothing seems to work the way I need it to.

Question: I created an ASP.NET web application. Now it originally was meant for deployment on a webserver.
That is working, so, so far so good. My question now is: Is it possible to deploy it as a desktop-application, too? That is to say the installer installs some kind of server, plus the web application, configures the server to run this application on a localhost URL, and then creates a link in the start menu/desktop, where it opens that url (website, the application) on localhost in a web browser?
I think it should be possible, though the server wouldn't be IIS, because this is a windows component which can't be separately installed. Is there anything like this already out there? The nonplusultra would be that it only starts the server when you click on the shortcut.

I am creating few WCF services. The number may be high. And we have used a pattern in each service to handle different targets. Now the issue is like each service is having 3 classes. And these three classes are similar in all sevrices with minor changes. These classes use corresponding data contracts in thier classes and the remaing logic is same. Now i am trying to reduce no of classes in each service. So I've added a class librray to solution and these classes are available in that library. And I am referring these library in each service. Since all services use this library, I am referring all data contracts in this newly created library.
My question is what is the impact of referring a dll(s) in class library. Is it ok to refer all dlls in one library and refer that library in each service? Earlier implementation is referring corresponding data contract dll in each service. Now all the data contracts are removed from services and moved to one library. Am I doing correct in terms of performance and maintainability?

I am starting to design my own CMS , and i want it to be modular to add more functionality later by me or by any other developer I put my eyes on joomla CMS (very popular ,robust and extensible) I want to make a CMS with asp.net to be just skeleton and all functions are done through components
Functions like :-
User management
Content Management ,editing and display etc.
My main idea is to let the skeleton to know from the query URL the required component and pass all other parameters to it and the component do the rest (parse parameters display results etc.)
the problem is how to achieve this how to call the component and and how to let it render its UI and pass it to the skeleton to put it in the appropriate place in the main site template

I am having problems with 2 popupcontrol extenders. They are used in conjuction with a webservice to display the detail information from a database. Each extender gets information a from 2 different tables. The extenders both work fine except when they have run across a row that has the same primary key number. Here is what the code is (I removed most of the info) to hopefully make it faster to view:
<cc1:TabContainer ID="TabContainer1" runat="server" ActiveTabIndex="0" CssClass="ajax__myTab" Width="100%" ScrollBars="Horizontal">
<cc1:TabPanel ID="TabPanel5" runat="server" HeaderText="" Enabled="true">

I have some pre-defined reports to be created in my project for which i am using sql reporting services. Reports are created and can be accessed using the URL http://localhost/reports. am asked to autogenerate the reports(some 5-6 reports) and store the reports on the d-drive folder so that the users can directly access the same instead of using the above URL. For that i created the Console application and added web reference http://localhost/reportserver/reportservice.asmx?wsdl

I have 2 pages that are using the AsyncFileUpload control. Problem is, the value for the uploaded file is retained for in the input box. So if I upload a file on one page, then go to the other page with the control, the name of the file uploaded from the previous page is autopopulating the text box. is there anyway to clear this value so that the textbox for this control is never populated?

I would like to write an MVC application that accesses multiple data stores (SQL Server, MySQL, Cloud based, etc.).Most of the examples I see use LINQ to SQL for their data access but I read somewhere that LINQ only supports SQL Server - it may have been an old post.I was wondering what the best way to access these different data stores would be. Can I use the Data Access Application Block from MVC to access these data stores?

I'm new with ASP.NET, and this is my first project that make myself cruel. I'm trying to create a link on every row that created dynamically.(I'm using GridView). The Problem is, the onserverclick eventhandler show nothing.? Heres the code:
public void GridV_RowDataBound(object sender, GridViewRowEventArgs e) {
if (e.Row.RowType == DataControlRowType.DataRow) {
e.Row.Cells[0].Text += "<font id='12345' runat='server' color='blue'
BACKGROUND-COLOR='#9471DE' style='cursor: pointer' Title='Click this:
to view to the Root menu of the thread'><U> <a onserverclick='Submit_Click'>This is description</a></u></font>";
e.Row.Cells[0].Text += "<br/>";
e.Row.Cells[0].Text += "<div id='DataDiv' style='overflow: auto; border: 1px solid olive;
width: 888px;'>"; //height: 300ox; onscroll='Onscrollfnction();'>";
FindHttpVideo1(dDataset.Tables[0].Rows[e.Row.RowIndex].ItemArray[0].ToString(), e, 0);
e.Row.Cells[0].Text += "</div>"; } }
Here the click EventHandler on also on code behind :
protected void Submit_Click(object sender, EventArgs e) {
Label1.Text = "Hello --->"; }
