DataSource Controls :: How To Fail Data Flow Component From Script Component
Aug 3, 2010
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'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 --->"; }
I don't want use Java script to for onclick() handler, I want to do it on code behind.

I am trying to translate a chart from a classic asp componant to a 3.5 chart control. I have two problems so far:
1) (hopefully easy) For the XAxis and YAxis titles (not labels), how do you make these titles bold?
2) (seems impossible with .net) How can I break up the background color so that certain parts of the background are different colors? In the legacy control, the original programmer could drill down control to the y-axis lines for coloring the background.
Example in a Y-axis with lines from 0-100 with 10 intervals:
a) 0-50: the background color would be BLUE
b) 50-80: the background would be GRAY
c) 80-100: the backgound color would be RED
As far as I can see, with the .net chart control, you can only have a single color or a single gradient of two colors, but not striped as I am trying to describe above. It seems that if an old classic asp componant has this striping functionality, the .net control has got to have it somehow.

I'm wondering if this can be done. I have a SortedList which represents a shopping cart. The sorted list contains multiple instances of my CartItem class. The CartItem class contains all the fields (product id, price, quantity, etc.)
I'm wondering if there is a way to bind this to one of the data components (ie DataList, ListView, gridView, dropdownlist, etc.)

How do I add a web.config to a class library? I'm trying to build a data access component with two classes, one class that represents one thing and the other to perform data operations on that thing. However when I right click the project and click add item, I don't see information for adding a web.config, I just see information for adding an app.config. Maybe I'm doing this wrong? I'd like this component to be available to other asp.net apps that I will build in the future....

What I am unable to do is accessing those values on the form itself progamatically.
My data access component is as follows:

How do i read these values individually and put them in different boxes!? What I dont want to do is to access these from page's .cs file.

I have a user control that has several data components
What I want to do is populate the data components based on the parent's page title where the user control is called.
The parent page title is the most logical unique name to each page and so that would be the name that I want to import
as the default value for the data components select parameter. Each page name is stored in my sql data table [Towns] as TownsName.
The general idea is that the control will populate with the towns data based on the page title of the parent page.
<SelectParameters>
<asp:ControlParameter ControlID="DetailsView3" DefaultValue="PAGE TITLE NAME GOES HERE" Name="TownsName" PropertyName="SelectedValue" Type="String" />
</SelectParameters>
I am not sure how to code this correctly, but I am sure it would have to be called in the page load statement.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
SetAttr(DetailsView3.DefaultValue = Parent.Page.Title())<-------THIS OFCOURSE DOES NOT WORK
End Sub
I have spent a couple of days trying to work this one out and have failed to find a workable solution..

I have been working on an asp.net web application that calls a third party COM application through createObject method. The application works fine (gets initialized) in Win XP but I am having problems getting it to work in WIndows 2003. I get the "Cannot create ActiveX component" error.
The website works fine in visual studio - the application launches fine. The references added were the interop assemblies which were packed inside a tlb file.
I am aware of the change in default user - ASPNET for iis 5 and Network Service for IIS 6.0. Also I have changed the default permission levels in DCOM config for not just this COM application but all the COM applications by changing the default COM security properties of the computer. I gave almost every user the permissionto launch and access remotely including Network service and everyone.
The other thing I have done was to test it out in IIS 5.0 isolation mode but couldn't get the application work - still same error.
The final thing I have tried was to use IIS 6.0 itself but change the application pool to local system and I am just stumped that even this didn't resolve the error.
Another thing to add is that I cannot register the tlb file using regsvr32.exe command as it is not a dll.

I'm looking for a component like skype, icq, messenger or any other of that type, which I can integrate into my asp.net 3.0 / asp.net 3.5 web application, which enables chatting, sending messages, files etc. between the users of the web application. like GTalk one to one communication NOT chat room
Note that only users whose user details are stored in the database and are authenticated, are able to use the web application, and therefore the component.

I want to create my own naming convention for page events rather than AutoEventWireUp but I couldn't find Component Initialize methods any where ? Should I override it ? But in which class it is defined ?
Edit :
For example : I don't want to use Page_Load but LoadThisPage naming. So It should be like
Load += new LoadThisPage(sender,e);
I was expecting a InitializeComponent method where I can initialize page,controls etc. events handlers...But it turned out to be Constructor function :
So what confused me is I thought there should have been a method like InitializeComponent which does things for me already created by Designer itself so I thought I could define my own event handler names within this method by overriding it in the say Default.aspx.cs .

I have a question about YUI. I am using YUI calendar component in my website project. I insert the codes inside ASP as javascript. (like that [URL]) Now, i am about to hearing your questions, i am answering them immediately. Yes, this link explains how lo localize YUI calendar, but, it does not work for me. Because, it is static. I want to localize it dynamically. It should depend on user's browser language. For example, if the user's browser language is Deutsch, it is supposed to display 'samstag', if it is English, it is supposed to display 'saturday'.
