I have made a mvc 2 asp.net application on a development server 2008 R2. The site works fine with IIS 7 and windows 2008 R2 on the development server... When I deploy the app to a remote accept. server, routing seems to be broken and only the master page with no contentplaceholders are rendered. I only see a empty Master page. It looks like the accountcontroller is not fired and no View is returned.

I have a very simple setup, single mycontrol.ascx with assoicated mycontrol.ascx.designer.vb and mycontrol.ascx.vb file. mycontrol.ascx embeds a single reference to a custom control: "MyMenu":
<mM:myMenu id="myMenu1" runat="server" />
This has created a protected reference in the mycontrol.ascx.designer.vb file:Protected WithEvents myMenu1 As Global.CustomControls.MyMenuNow, when I breakpoint the Page_Load() event of mycontrol.ascx, and inspect the members returned from the type via:
Me.GetType().GetMembers()
I cannot any reference to myMenu1. If I look at the control with intellisence, the property is accessible:
Me.myMenu1 Can anyone explain exactly what I'm missing and what I need to do to access designer created properties at runtime through reflection?

I'm working on ASP.NET 4.0 and I'm having problems for saving the selected value in a DropDownList.
I initialize it in the Web Control's PreRender method as follows:
if (!Page.IsPostBack)
LoadCountryList();
Where LoadCountryList's code is:
private void LoadCountryList()
{
var vr = new CountryRepository();
var countryList = vr.GetAllForList();
DdlCountry.EnableViewState = true;
DdlCountry.DataValueField = "code";
DdlCountry.DataTextField = "name";
dlCountry.DataSource = countryList;
DdlCountry.DataBind();
}
After I submit the form, I've noticed the DropDownList is empty(it's not before postback). If you take a look at my code, I've enabled the ViewState for this control, but I'm not getting any results yet. Does anybody know what's going on?
EDIT:
Here is the simple code of the control in the aspx file:
<asp:DropDownList Runat="server" ID="DdlCountry">
</asp:DropDownList>
I've looked at answers to some similar question but I still can't seem to figure this out. I think I'm misunderstanding something about how ASP.NET works.In the standard ASP.Net 4.0 'Create a new Account' form, I've added a DropDownList containing Roles to be selected for the new account. in the aspx page, the control looks like this:
<asp:DropDownList ID="RoleList" Width="100px" runat="server"></asp:DropDownList>
I am then populating the List in the Page_Load Event:
protected void Page_Load(object sender, EventArgs e)
{
RegisterUser.ContinueDestinationPageUrl = Request.QueryString["ReturnUrl"];
[code]....
I have a dropdownlist on my page with dates such as 1/1/2013, 2/1/2013, etc.
Then there is a second ddl.
If the date in ddl #1 is before 1/10/2013 I want to enable ddl #2.
If the date in ddl #1 is on or after 1/10/2013 I want to either disable ddl #2 or hide it (whichever's easier).
Disabling ddl #2 based on the selected date is a new requirement so I am enhancing the existing code. Obviously I want to do this without a postback, but I don't know what is the best way. I am trying to understand what an AsyncPostBackTrigger is because this is the existing code:
Code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:dropdownlist id="EffectiveDateDropDown" runat="server"></asp:dropdownlist>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="QuoteType"
EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
It wants to do something when the selected index is changed? This exists in the code-behind, but I set a breakpoint and never hit it:
Code:
protected void QuoteType_SelectedIndexChanged(object sender, EventArgs e)
{
try
{
}
catch (Exception err)
{
this.PublishError(err);
}
}
After setting the auth cookie using
FormsAuthentication.SetAuthCookie("myusername", False)
server.transfer("somepage.aspx") to open a web page.
Context.User.Identity.Name is found to be empty
But if I use
Response.Redirect("somepage.aspx")
Context.User.Identity.Name provides correct result.
I am aware of the differences between Response.Redirect and server.transfer. But exactly what is the reason behind this particular behaviour ?
I intend to add dropdownlist and Textbox Controls at Runtime as below:
CustomerID
I have a message in a greyed out with a message.
"There are no usable controls in this group. Drag an item onto this text to add it to the toolbox."
What do I dow with this?
A web site project, 4 pages. First page just has button links to redirect to another page. When button link is cliced, the data is retrieved from SQL Server through stored procedures and they are in a class file. Able to call the procedures and pass the information through SET Properties and right before the page is displayed, checked and data is in the dropdownlist control then redirect to show page. The dropdowlist is empty, should I be using something different to show the page with the data? Have tryied REDIRECT and then fill dropdownlist and its still empty on displayed.
