I have a user control in silverlight which contains both XMAL and .cs file. But I wanna make it into a base control. In other word,I can make a control inherited it whose area in it can be edited. Just like Master Page in asp.net,you know. In the base control,I only have a lot of description in XMAL,perhaps it can be described in the .cs file,too.
View 1 RepliesDo we have to do something special to have ASP.NET partial classes aware of controls that are declared in our user control's base classes? The partial classes keep generating declarations for controls in the base class which mean the controls in the base class get hidden and are null.

I am new in asp .net.I am not able to undestand why we call base class method when we
override methods/events.Like automatically visual studio will put base.OnInit() if you are overriding OnInit.
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
}
same is the case of Finalize. In derived we call base.Finalize() Is there any need of calling these base class methods ?
I have to implement User base security in my Web project using .Net3.5. Followings are some we need:
Roles can be Admin, Manage, Editor, Member etc User can have multiple roles Every roles has its own dynamic menus and restrictions/resources All menus and interface will populate dynamically from Database
I heard some where this kind of i.e user base security can be implemented using HashTable but I dont know how is it?
Today I came to know that for this kind of work Java people use Interceptor Design patterns. So, how could I do the same in asp.net C#?
I have a main silverlight control named MainPage.xaml in an asp.net web site.
I want to dynamically add and remove control at run time.
So, I have created another control Top10.xaml and added to selected canvas area on MainPage.xaml as described on this page(Click Me):
Now i need to modify Top10 visibility in MainPage.xaml dynamically when a button is clicked on MainPage.xaml using C# code in MainPage.xaml.cs.
i want to disable validation controls on some conditions. how can i find that a control is inherited from "BaseValidator"?

In a recent post, I expressed a need to access the properties for the body using declarative syntax, see
Contentplaceholder for replacing attributes?
But, the syntax confuses the editor which is not acceptable.
My hypothesis for a workable solution is to make the change in code. To derive a class from System.Web.UI.Page with extended functionality. However, I want for the designer to be able to still use declarative syntax to set the body tag.
I do not want to have to change any code in my aspx web pages except that they derive from base I want to be able to set these properties using declarative syntax, merely by adding a tag in the derived page I'm not immediately sure how to go about doing this because it doesn't exactly fit the OOP paradigm and I'm not sure where the changes need to be made.
I can use a findcontrol in the base to see if the placeholder has been added. But, not sure exactly at what point in the page processing lifecycle that I can use this findcontrol. I need to set the body before it renders but also be able to grab something from the declarative code.
Is it possible for a derived controls to inherit his base control skin.
Say I am deriving a control from TextBox, is it possible for the derived control to inherit the skin settings for Textbox or do they need to be defined again?
I am applying the default skins to all controls through the styleSheetTheme Page property I am using the Devexpress asp.net controls if that makes any difference.
I have a progress bar (which is a user control). When user, click a button, this progressbar will get displayed. The issue is ...even if the progressbar is visible, I am able to set focus to other controls in base page. I need to blur the base page...and set focus to user control.
View 2 RepliesI have a base user control (inherited from System.Web.UI.UserControl)
public delegate void MyEventHandler(object sender, MyEventArgs e);
public event MyEventHandler ControlLoaded;
//Fire the event from here
protected override void OnLoad(EventArgs e)
{
MyEventArgs cmdEventArgs = new MyEventArgs("somearg");
ControlLoaded(this, cmdEventArgs);
}
I have several controls that are derived from this base user control.
On the host ASPX page, I need to subscribe to the ControlLoaded event.
protected void Page_Load(object sender, EventArgs e)
{
//subscribe to the event
//This line DOES NOT WORK as I cannot attach event to a base control - It needs an instance of the user control which I don't have
BaseUserControl.ControlLoaded += new MyEventHandler(ControlLoaded);
}
private void ControlLoaded(object sender, MyEventArgs e)
{
// some control has been loaded
}
How do I subscribe to the ControlLoaded event?

View 1 RepliesI don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
I have a user control (uc1) which inherits from uc2. uc2 has a user control (uc3) declared in the markup. I am trying to access uc3 from uc1 but I get NullReferenceException. I thought due to inheritance uc3 would instantiate but looks like I am missing a step.
Clarification:
How does the child user control inherit the markup from the base class? The server controls in the base user control are null in the code behind of the base user control. Why?

i have a base user control (WC1) which inherits from WebUserControl and a child user control (WC2) which inherits from WC1. I added a textBox and a label to WC1 in vs design view not code behind. But all the server controls that i put in WC1 are null and give null pointer exception.I tried to access textBox and label in different events but the all of them are null.
Steps to reproduce the error:
create a web user control called WC1 by add a new item in VS added a textBox and label server control to WC1 in design view of VS and put code behind: var value = txetBox.Text; created another web user control called WC2 by add a new item in VS and change its base class to WC1 in its code behind create a web page by adding a new item in vs and drag WC2 to the design view of the page run the page then you will see the exception for the codebehind in WC1
[code]....
page:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="WC2.ascx.cs" Inherits="WebApplication1.WC2" %>
can web server controls of WC1 be instantiated in this case? or can user control inherit from another user control and web server controls of parent user control be carried to its children without worring the layout?
We have a ASP.NET web application written in VB.NET where we build content programmatically during the Init event.
We make extensive use of user controls, building them on the fly, and I now want to start including SilverLight content.
Is there an easy way of embedding a SilverLight application in a control, and then instantiating the whole thing in code, in the same way as you'd programmatically add ordinary ASP.NET controls to a page?
The SilverLight component itself works fine when added to a page using the <object> tag but I really want to be able to reuse it elsewhere in code.
Since I'm expecting use of SilverLight to increase in our application, and the asp:Silverlight control seems now to be deprecated, I'm looking for an alternative way of wrapping the content.
Iīm just starting to program for the web, so please bear with me. I need to develop a website with a connection to a database. I would like the database to be access, but if necessary I can upgrade it to sql server. In visual web developer, I know how to connect to the db, and it works so for the moment thatīs ok. However... thereīs got to be something very wrong with the vwd. Even the simplest things donīt work. I canīt even place a textbox right. when you change a property, nothing happens. The controls are all over the place, they even move from the default.asp to the master page. 90% of the time is spent on trying to figure out how to get rid of borders from a table and such stupid things (wich by the way is impossible). So I thought of silverlight.
But then of course thereīs the thing with the data interchange. Iīve learned to send variables via querystring. However that wonīt do when I want to dsiplay a large table of data in a gridview for instance. So Iīve gathered Iīm supposed to use RIA. I studied this tutorial [URL] Itīs just that when Iīm supposed to put the domaindatasource control on the asp page, itīs not there. And when I try to add it via the "choose item", itīs not in the .net list. Itīs in the silverlight list though. Is vwd supposed to be this bad? Itīs ridiculous really. Or did I mess up the installation? I use the express version of 2010. If you know of a good tutorial please point me in that direction. I donīt know any c# though so that wonīt work.

I'm building form validation controls for our C# ASP application. The bulk of the work is handled by a BaseValidator control (subclassing System.Web.UI.UserControl), which also has the markup for the validation output. This is then extended by subcontrols like PasswordValidator, that provides the Validate method and any extra fields needed by that validator control.
(The end goal is to have controls like <uc1:PasswordValidator ControlId="txtPassword" /> which we can plop into any form with minimum duplication.)
However, PasswordValidator.ascx.cs cannot access the form elements defined in BaseValidator.ascx; the only way I've found to do so is to duplicate the markup in each subcontrol's *.ascx file. How can I extend BaseValidator.ascx.cs and access BaseValidator.ascx's markup in the subclass?
