How To Expose Child Control Style Properties In A Custom Composite WebControl

Feb 23, 2010

I am writing a custom composite WebControl and want to expose styles of child controls it encapsulates to the ASP.NET designer. The code I currently have is similar to the skeleton below (which for simplicity only has one child control).

With the code below, I can see property "ChildPanelStyle" in the designer, but when I try to modify one of the properties (e.g. CssClass) in the designer, it immediately resets itself to its default value. It looks like the designer serialization isn't happening.

What am I doing wrong?

UPDATE

I've updated the sample with an additional style property that is managed directly by the custom control, rather than simply being the property of a child control.

The HeaderStyle property is persisted properly by the designer, but the ChildPanelStyle property isn't.

Of course I could manage all my styles like HeaderStyle, and apply them during rendering, but I'm hoping there's a simpler solution whereby child controls can take care of themselves, and I don't need any custom rendering.

Security :: How To Expose More Properties Under User Class

Jul 16, 2010

I am using a custom membership provider. I want to expose additional properties under User class.

So in my custom membership provider class I added few Properties (FirstName, LastName, Address, etc) and set their value in ValidateUser(). However back in aspx.cs if I type User. I do not see FirstName, LastName and Address in intellisense.

Is what I'm attempting to do even possible? Or do I need to resort to using my own custom user class? In which case I wouldn't need to use custom membership provider because I can program my custom user class to do everything that custom membership provider can do. Only thing is I would need to pass this user object in session object.

Does A Composite Server Control(inc. User Control, Custom Server Control) Normally Encapsulate Css Properties?

Nov 7, 2010

If a composite server control normally encapsulate styling information inside, it is an example of code encapsulation and modularization. However if css properties are included inside the composite control, it is not ideal for code/styling separation and css code re-use principles. Now which consideration should be the main consideration?

How To Expose A Panel As A Property In User Control

Aug 20, 2010

I have a user control with a panel on it:

CustomControl.ascx
<%@ Control Language="vb" CodeBehind="CustomControl.ascx.vb" %>
<asp:Panel ID="myPanel" runat="server"></asp:Panel>

I'd lke to expose that panel as a property that I can use at design time.

CustomControl.ascx.vb
<ParseChildren(True), PersistChildren(False)> _
Partial Public Class CustomControl
Inherits System.Web.UI.UserControl
#Region "Members and Properties"
<PersistenceMode(PersistenceMode.InnerProperty)> _
Public Property SomePanel() As Panel
Get
Return myPanel
End Get
Set(ByVal value As Panel)
myPanel= value
End Set
End Property
#End Region
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Response.Write(myPanel.HasControls.ToString())
End Sub
End Class

And then bring the control onto a page like so:

<ucl:CustomControl runat="server">
<SomePanel>
<asp:Label ID="lblText" AssociatedControlID="txtBox" runat="server"></asp:Label>
<asp:TextBox id="txtBox" runat="server"></asp:TextBox>
</SomePanel>
</ucl:CustomControl>

When I run the page, HasControls is true but nothing is rendered. What am I doing wrong?

Custom Server Controls :: Custom Control's Constructor / User To Set That variable In The Properties Window After They Drag The Control Onto A Form?

Mar 4, 2010

I have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.

Is there a way for the user to set that variable in the properties window after they drag the control onto a form.

I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.

Right now, I have to create the control dynamically. I read the query string and then created the object.

Custom Server Controls :: Composite User Web Control - Properties - Best Practice

Jan 12, 2011

I would like to ask you what is the best practice for developing composite user web control with multiple controls inside from the stand point of dealing with properieties. In my situation I would like to use header menu bar with logos, buttons, java baset visible/hidden menus itc as web control. I was successfull in implementing new control in my project.

But my question goes to issue of properties for ALL OF controls. I know how to hard code all required properties like: text, visible, enable for all controls. It's a lot of work. ( This is the very edge of my asp.net comprehension ) Is there a more elegant way provide an access to controls's properties without hard coding seperatelly?

Custom Server Controls :: Accessing Properties Of A User Control From The Inherited Code Page?

Mar 8, 2010

If the answer to this question exists somewhere, I'm no good at searching for it. This is sort of a simple question, the response being two parts: (1) is it possible? (2) if so, how?

I've created a web user control for my site's footer. In my web.config I have it registered like this:

[Code]....

Then, within the pages on my site, I simply insert it like this:

[Code]....

But obviously, that didn't work. I get this error: The type or namespace name 'FooterControl' could not be found (are you missing a using directive or an assembly reference?)

So I'm really not sure what to do at this point. I can put all of my code in the ASPX file and make my life easier, but I would kind of prefer not to.

Custom Server Controls :: How To Get The Value Of Readonly Properties Of Server Controls Inside A Custom Server Control

Apr 4, 2010

I have a custom server control inheriting from CompositeControl. It consists of two RadioButtonlist controls that are rendered side by side in an html table. The number of ListItems in each RadioButtonList is not known until runtime. Depending on how many items each list contains, the RepeatColumns property of each list is set differently. To do this in the handler for the ItemDataBound event I need to get the count of ListItems in each RadioButtonList. How do I expose the Items.Count property of each internal RadioButtonList as a top-level property? I tried using a getter to return the count but this generates a compile-time error to the effect that the count cannot be assigned to--even though I have not created a setter.

Similarly, in the handler for the Submit event, I need to get the ClientID of each internal RadioButtonList to pass to a method that checks for data changes. How do I expose the ClientID of each component RadioButtonList as a top-level property?

I can of course index the Controls collection of the composite control to access the child control and read its properties--but that defeats the whole point of making a complex, independent custom server control.

C# - How To Expose A Repeater's Templates From Another Control That Contains The Repeater

Sep 30, 2010

If I have a custom user control (say, MyCustomControl.ascx) which contains a number of other controls including a repeater, is there any way to expose that repeater's templates as templates for MyCustomControl?

For example, I would want to be able to do this:

[code]....

There could potentially be more than one repeater or other templated controls within the parent control, in which case I would like to be able to expose all of those templates for all of the controls in the same way.

My first thought was to simply expose the repeater's templates as ITemplate properties on MyCustomControl, but that didn't work since there's no (obvious) way to access the repeater's DataItem from the templates doing it that way.

The above code compiles without any error. Also I can drag and drop this control from the Toolbox of my Project on my web form. However I am unable the change the value of my fromLabel control.It allows me to change the value in the properties window.But when I run the form it always shows me its default value which is "From". I want it to be flexible so that any one can change the value in the properties window.

Expose A WCF Service Via Forms Authentication In IIS - How To Make The Metadata

Aug 16, 2010

We've got some WCF services we're hosting via IIS. The application in general uses Forms Authentication, and we'd like to continue making that available for web service clients. We just have a <authorization><deny users="?"> in our web.config and some authentication/redirection goodness that gets everything done.

The problem is we'd like for users to be able to access the metadata for the services without authentication. Can they visit /services/v1/ArtifactService.svc?wsdl anonymously and yet still require authentication for /services/v1/ArtifactService.svc/rest/GetArtifacts?studyId=123? If so, I can't figure out the right incantation in the configuration.

The best I can think of is to set an absolute URL in the metadata service behavior, but then I have to doctor the path on install anywhere we deploy. (<serviceMetadata httpGetEnabled="true" httpGetUrl=[URL]

Web Forms :: Assign Properties For Button Control At Runtime?

Dec 5, 2010

I have a button in a details view that I want to change the properties of at run time. When the user clicks the edit button the details view goes into edit mode. I also want the edit button to turn into an update(or save) button so the use can click it to persist the changes done in edit mode. I've had to create a new instance of the button which I can do. I've done that with the cast below, I assume this is a good way to do this. I'm now having difficulty assigning the properties. I tried this but get a "Object Reference not set to an instance of an object" error. I thought I was working with an instance of the object in the code below, but the compiler doesn't agree. How do I set the text, and other properties for my button instance?

Web Forms :: Dynamic User Control And Setting Properties?

Jan 25, 2011

I have a user control (i.e. ascx) that comprises of two related list boxes (i.e. once you change the selected item in one list the contents of the other list update). I'm adding this user control dynamically to a page on the click event of a button (i.e. using LoadControl).I wish to set the list box datasource properties, as well as the default selected item of the parent list from my parent page so I created public properties in my user control to accomodate this. I also created an event in my user control that notifes the parent page when the selected item changes in one of the list boxes so I can update the contents of the other list box.

I understand that I have to recreate the user control on every postback in order for it to function correctly but I'm not sure exactly how I should be doing it. I've shown below what I have currently - whilst it works the problem is that on postback I'm always creating the user control with all its default properties and then updating the properties that need to change(?). For example, when the choice in theparent list box changes the datasource of the list box is set twice (once in AddControl and then again in OnParentChanged)? As the contents of the list boxes originate in a database it means I'm making unnecessary calls to the database (unless I do some something like store each unique set of data in the ViewState).

I'd be very grateful if someone could review how I've done things and illustrate how perhaps I should be doing things. I'm not sure if the way I've done this is considered the 'correct' way. For example there may be a better way of doing things would avoid setting the properties twice? I'm a bit unsure of the way I've set the datasource properties of the list boxes and bound them. I wished to set the datasource from the parent page because I might have a second user control on my page that may also use the same datasource and I could reuse it (as opposed to each control making its own call to the database) so I'd like to keep this feature if possible.It would be great if posting code in reply that you use my example as a guide so I know what you're referring to.Here's the code for my user control:
