User Control controls not created when dynamically creating user control
  Have created a user control for displaying and editing a dynamically number of values. The user control contains two labels and an edit box. When dynamically loading the user control I get an error when the control itself tries to change setting on the fields within the user control.   Why doesnt this work? It works okay if I dont load it dynamically but create a user-control-instance in the aspx-page but thats no solution.   Thankyou!     Here is my code:   ucDataValue.ascx   <%@ Control Language="C#" AutoEventWireup="true&...

Using controls from pages, master pages, and user controls
How would I structure my site in this scenario: I'd like to use a dropdownlist all over my site, sometimes in a regular page, sometimes in a master page, and sometimes in a user control.  I wish to bind its events programmatically, so normally I would just put that in the codebehind.  However, I notice a lot of code duplication because I have to declare the control in everywhere, in my base page (which all my pages inherit from), in my base master page (which all my master pages inherit from) and in my base user control (which all my user controls inherit from).How should I be...

Master Control
I find Master Page idea brilliante. But wouldn't it be nice to have an ability to assign master layout for user controls? Does anyone know of something like that? Look into Themes and Skins. Skins are user to set a template for a contol.Themes and SkinsThemes and Skins 2 www.hopeasp.net Hmm Sean, themes and skins will only help with STYLING the components not layout. What I need is something to set the LAYOUT of the user control and use that master layout to place components in. Like in master page but in user controls.Simple example: Master Control fileUsercontrol layout st...

Problem adding a Dynamic Control to a page FROM a User Control
I've made a set of user controls that consist of text boxes with rangevalidators tied to them. I'm trying to make it so that if there is not validation summary present on the page that the user control is dropped onto/used on, the user control will also inject into the page a validation summary control.  Of course with user controls you cannot override the PreInit() method, which is normally where you create dynamic controls. So when I attempt the following code in either Init, load, or prerender:     Protected Sub Page_Init(ByVal sender As Object, ByVal e As EventArg...

Creating a User Control validator that validates a control on the page, rather than inside the control.
I'm trying to create a custom user control that is nothing more than a RangeValidator that validates other controls that lie on the page rather than inside the control itself... is this possible, is there a way to "bubble" it up. Thanks, G My answer to your other question regarding the CompareValidator applies here. If the custom control is in the same naming container AND does not implement INamingContainer, you can create a property that lets the user assign the control to validate. Internally assign the Validator.ControlToValidate property to the value of that property.-...

Need to access a Label Control on the Master Page from a user control attached to a content page
Hello all, I have a master page (say  site.master)  with a status Label in it. I have a content page ( say content.aspx)  that has a user control (say usercontrol.ascx).

I have been able to do this directly off a content page (content.aspx) by using the following code (VB)  on the master page <%@ MasterType virtualpath="~/site.master" %> and Dim mpLabel As Label = CType(Master.FindControl("LabelStatusMsg"),...

Single page with multiple user web controls VS Multiple page with specific user web controls
I have a question regarding single page with multiple user web controls vs multiple page with specific user web controls   Option 1: I am of the opinion to have multiple pages with specific user web controls and use an object to store all the information as the user navigates through the application. And finally at the end, read this object and save all the information to the backend database.   Option 2: My respected team member suggests that we have only one page, with all the specific user web controls and not use an object, instead show/hide the user web controls based ...

How to access page control (editor control) from user control?
Hi, I want to do something, but I don't know if it's even possible. I'm trying to make a simple application to edit my website. I have a page called editPage.aspx which contains an editor control.
