Hi All,
I am deploying my website by using add webdeployment project.
But in my website i have used the WebUserControls in my website. The WebUserControls events are handled in form[which contains WebUserControl] through Delegates & Event Handlers.
These events of WebUserControl have been initialized at form Default.aspx Page Init event.
When i build the Project it gives no errors, the site runs perfectly...
But when build the Deployment project i got a compilation errors of WebUserControl events where i initilized at form Default.aspx page init event.
Its giving error message like 'MyUserControlUC' could not found are u missing add reference.
For sample:
==========
MyUserControlUC.ascx
<pre>
<scrpt runat="server">
//delegate
public delegate void DropDownSelectedIndexChanged(object sender, EventsArgs e);
//event
public event DropDownSelectedIndexChanged IndexChanged;
//call the event
protected void ddl_items_SelectedIndex_Changed(object sender, EventsArgs e)
{
if(IndexChanged != null)
IndexChanged(sender,e);
}
| <asp:dropdownlist id="ddl_items" runat="server" autopostback="true" onselectedindexchanged="ddl_items_SelectedIndex_Changed">
|
Default.aspx
<%@ Register TagPrefix="uc1" TagName="SampleUserControl" Src="~/MyUserControlUC.ascx" %>
<html>
<head></head>
<body>
<form runat="server">
<uc1:SampleUserControl BackColor="Gray" id="SampleUserControl1" runat="server"></uc1:SampleUserControl>
</form>
</body>
</html>
Default.aspx.cs
<pre> protected override void OnInit(EventArgs e)
{
base.OnInit(e);
InitializeComponent();
}
private void InitializeComponent()
{
this.Load += new EventHandler(this.Page_Load);
SampleUserControl1.IndexChanged += new ASP.MyUserControlUC.SelectedIndexChanged(ddl_items_SelectedIndexChanged);//Here i am getting error while building deployment project.
}
private void ddl_items_SelectionIndexChanged(Object sender, EventArgs e)
{
//Code here to handle ...
}

If you are having the UCs in different project from the main web site, then check if the Build order of the solution is set correctly and check if you have enabled compiling the primary assembly and all it dependencies.
HTH!

mm, try qualifying the UC with it relative path like so -
<%@ Register TagPrefix="uc1" TagName="SampleUserControl" Src="~/MyUserControlUC.ascx" %><br />
This denotes taht "MyUserControlUC" is available in the application root folder.

Hi Dinesh,
Sorry for late response...
The exact error message is
1.System.Web.UI.UserControl does not contain a definition for 'IndexChanged' and no extension method 'IndexChanged' accepting a first arguement of type 'System.Web.UI.UserControl' could be found.(are u missing a using directive or an assembly reference)
2.The type or namespace name 'MyUserControlUC' doesn't exist in the namespace 'ASP' (are u missing an assembly reference?)
This error i got at Default.aspx.cs page
private void InitializeComponent()<br />
{<br />
this.Load += new EventHandler(this.Page_Load); <br />
SampleUserControl1.IndexChanged += new ASP.MyUserControlUC.SelectedIndexChanged(ddl_items_SelectedIndexChanged);
}
regards,

From the first post, your IndexChanged event is of type (Delegate) DropDownSelectedIndexChanged. Where as you are trying to assign it to a delegate of type MyUserControlUC.SelectedIndexChanged. You should actually be assigning it to MyUserControlUC.DropDownSelectedIndexChanged.That is what the error message implies too.
You have used the namespace qualifier "ASP" to assign the IndexChanged event handler. Is this namespace correct??
Try the changes, it might do the trick.
HTH

Hi Dinesh,
Thanks for your response.
That was not a problem, because the application is running perfectly and the dropdown event fires and giving the results to me.
No errors while building and running the WebSite.
But there are bulid errors while building the DeploymentProject of above website.
The errors i already posted in my above post.
Thanks & Regards

Hi,
I have a file in other computer say (\\10.10.10.10\\sharedFolder\abc.txt) and asp.net is running on local computer
Can I use Response.WriteFile to server this file when client requested.
Response.WriteFile("\\10.10.10.10\\sharedFolder\abc.txt");
But I am getting an exception saying file does not exists at location :
c:\\inetpub\\wwwroot\\10.10.10.10\\sharedFolder\abc.txt
Please let me know how we can do this.
Thanks,

It is not a good practice to access the file system except your application root from a web application. If you should then you need to use a user credential with a elevated access rights than the default IIS user. Server admins won't let you do that.
BTW, Response.WriteFile does not read a file, it writes the response to the file on the current execution directory. To really write into a file you need to use File objects.
Do you want to write data into the file or read the file and display the data to your users on your application?

Try using following if the file is on the same server
Response.WriteFile("~\\sharedFolder\abc.txt");
Or use following if the file is not on the same server
Response.WriteFile(@"http://10.10.10.10/sharedFolder/abc.txt");

Hi,
I am developing small web application(ASP.NET and MySQL)with CURD Operations which has one table and has 30 columns.

Suppose If more than one person tries to modifies the same row(record) then it should throw message as "Someone already editing the record".
I find out optimistic and pessimistic locking for the above problem.
How to achieve this one and which method to use any sample application which will be very useful
