I have a class (name PageBase) that is inhariting System .Web.UI .Page and all my .aspx page behind classes are inhariting this class. This way I have put some common things in PageBase class.
For showing errors I want to put showMessage funtion in PageBase as well so that I may have not put it in every page and it will easy to manage this way.
Probem is that how PageBase class will access a control which is in aspx page in its child class (child class of PageBase) .
I dont want to pass control as argument to function in parent class, is ther any other way ?

Imagine, a model like this:
[AddressValidation]
public AddressType[] Address { get; set; }
internal class AddressValidation : ValidationAttribute
{
public override bool IsValid(object value)
{
//Assume we are valid
var isValid = true;
//Cast to something useful
var addresses = (AddressType[])value;
var defaultAddresses = addresses.Count(a => a.AddressCode == AddressCodeEnum.@default);
if (defaultAddresses == 0)
{
ErrorMessage = "One address must be the default address";
isValid = false;
}
else if (defaultAddresses > 1)
{
ErrorMessage = "Only one address can be the default address";
isValid = false;
}
//Return the result
return isValid;
}
}
When the model is validated by the controller, any of the subordinate addresses are properly validated and any errors are returned as modelstate errors. However, the custom attribute's error is never added to modelstate, even though it validates false. It seems as if this should work, the validation is called and I can step through it - it just never gets added to modelstate.

I have a WCF service that when the objects serialize to clients an extra property is getting added with a 'Speficied' suffix. At first I thought it had to to with a couple of nullable type properties, but it is happening to all of my value types even if it is not declared Nullable. How can I get rid of this?

I have this code in an .aspx file, within a sqldatasource control.
<asp:controlParameter
Name="WH"
ControlID="rblWH"
DefaultValue="DL"
Type="String"
Size="2"
Which currently uses a 2 character code from a radio button list as its value. It is used as a parameter for a stored procedure. Somewhere else on the page I have a combobox called cbTripPick with that 2 character code embedded within its text property. I wish to use that 2 character substring as the control parameter instead of the above. Can I do something like this ?
<asp:controlParameter
Name="WH"
ControlID="cbTripPick"
PropertyName = "some function or expression or eval that will give me the 2 char. value from the cbTripPick control"
DefaultValue="DL"
Type="String"
Size="2" />
Is it possible to declaratively set the propertyname to some dynamic expression which will get me what I want? Or should this all be done programmatically?

I have a class named utility in my App_code folder that holds the logic to set a labels text.
public void Mgr_BreadCrumbs(string text)
{
Manager.MasterPages.Master master = new Manager.MasterPages.Master();
Label lblHeader = (Label)master.FindControl("lblHeader");
lblHeader.Text = text;
}
And then in each of my pages I was trying to set it like this:
utility u = new utility();
u.Mgr_BreadCrumbs("Categories");
I'm getting am object reference not set to an instance of an object on the lblHeader.Text = text; line of code.

How do I create an ASP.Net MVC Helper for an Html.Label which takes in attributes? Currently when I define an Html.TextBox I am able to pass in a list of attributes. Sort of like below:
new {disabled="disabled", @class="pcTextBoxWithoutPaddingDisabled"})%>
However, it does not look as though the Html.Label has this feature. As a result, I have to define my labels using the label tag. Sort of like below: <label class="pcLabelBlackWithoutPadding"> I would like to be consistent I how my Html element get created. So, how do I create an Html.Label that will take in a list of attributes?

I have a page on which the user can define a query. When done, the user enters a name for the query and presses a button. I'd like to process the button click, make a text label (or Span) visible for a few seconds and then have it fade out.
Since it is a postback, I can turn an ASP:Label control to visible - that's easy. Now how do I get jquery to make the label fade away after a few seconds? In a broader sense, how do you get a postback to trigger a jquery method?

All I want to do is learn how to create a class procedure. And then. How to call it. As an example, A + B = C is the procedure. I would create a class. Right? Then do I name the procedure and put it in the class? Or create a new class for each procedure? Then I would want to, on a local level, substitue values for A & B to return C. So, if the public procedure exists, how to I call it? I know that this is really simple stuff, but I need examples to be simple.

I am trying to create a pageBase class where I can dynamically pull data from the database and display it on a web page. Each page I specifically set an ID for the sql query which pulls back the information such as page title and page text.
my problem is that I can't seem to pass the information captured from the query to the page. I get problems such as can't convert string type to literal and I need to declare a new keyword to an object.

A instance of a class is created in the partial class of an aspx page.Under page_load or button click method I'm trying to set the value to the class. but when each postback takes place new instance is created and I'm losing the previous value.
public partial class DatabaseSelection : System.Web.UI.Page
{
DBProperties dbpro;
Metadata obmeta;
protected void Page_Load(object sender, EventArgs e)

My ultimate goal is to create a UserControl in a class in my App_Code folder and render the html from that into a string.
The rending of HTML can be done using this example I believe:
How do I get the HTML output of a UserControl in .NET (C#)?
My Question:
I created my user control
public partial class Controls_MyUserControl : System.Web.UI.UserControl
I've registered it in my web.config
<add tagPrefix="UC" src="~/Controls/MyUserControl.ascx" tagName="MyUserControl" />
I can reference this on a page just fine
<UC:MyUserControl ID="MyUserControl1" runat="server" />
Yet when I try to create an object of this control type in a class (in my app_code folder) it doesn't allow me.
Controls_MyUserControl dummy = new Controls_MyUserControl();
The potentially strange thing is when I put this code into a code behind of a page, it works.
what I need to do to have the usercontrol to be able to be created in my class in the app_code folder?
My guess is, is that I need to reference the control in a "using" statement at the top, but I'm not sure what that'd be.
It's not in a namespace to my knowledge (at least there's no namespace, in the code behind of the actually user controls). Though I'm not sure if it inherits one from the System.Web.UI.UserControl.
