Web Deployment error for WebUserControl event [modified]

K V Sekhar

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

//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);
}

Default.aspx

<%@ Register TagPrefix="uc1" TagName="SampleUserControl" Src="~/MyUserControlUC.ascx" %>

Default.aspx.cs

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 ...
}

Thanks & Regards

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!

Hi Dinesh, Thanks for ur reply. But the WebUserControl are in sample project.i.e, in main website it self Regards, kv sekhar

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

Hi Dinesh, <%@ Register TagPrefix="uc1" TagName="SampleUserControl" Src="~/MyUserControlUC.ascx" %> is right, in the post i wrote wrong. In register tag no error. Problem with at Initilization of UserControl events in form. any suggestions is appreciated.. Thanks & regards, kv sekhar

Can you post the exact compilation message and the reference line number? Well, I can't think of whats going wrong. Hard luck.

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() { 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. } regards, kv sekhar

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 kv sekhar
