attribute to theme server control according to arbitrary type

Posted By:      Posted Date: October 21, 2010    Points: 0   Category :ASP.Net

I have a server control that inherits from System.Web.UI.Button, say MyNamespace.SpecialButton.  I want the theme engine to treat all instances of SpecialButton as instances of System.Web.UI.Button.  Some time ago, I was able to achieve this in another project by decorating a server control with attributes in such a way that the control would be treated as another type by the theme engine.  Unfortunately for me, I've forgotten how to do that, and I'm unable now to find any reference to that method in searches.

Can anyone help with this?

Composite Control which contains arbitrary content defined in .aspx of parent and thier ViewState


I want to write own control which can contain other. And I want to define content of the control in the .aspx file where the control is defined. I have written such control. But now I have issue with ViewState of inner controls of my control. The following samle illustrates the issue: I defined two asp:DropDownList ID="ddl1" and ID="ddl2" One of them is inside of my control and other is outside. When posback is occurred asp:DropDownList ID="ddl1 loses state and becomes empty. How to say ASP.net to store state of inner controls defined by this way?


<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="MyControl.ascx.cs" Inherits="DynamicControls.Controls.MyControl" %>

<div class="box">
    <div class="Header-Left">
        <div class="Header-Right">
            My Control
    <div class="Content">
        <asp:PlaceHolder ID="contentPlace" runat="Server" />

Custom Server Control Property not maintaining state


I have created a server control consisting of a TextArea and a div under it.  My goal is to create my own asp:TextArea type control.  the div is for a Character count of the text area and seems to work ok but i added a CharacterCountVisible property to the control that is always returning true.  See Proptery definition below


<Bindable(False), Category("Appearance"), DefaultValue("True"), Localizable(True)> Property CharacterCountVisible() As Boolean
        Return _CountBoxVisible
    End Get
    Set(ByVal value As Boolean)
        _CountBoxVisible = value
    End Set
End Property

Note the _CountBoxVisible variable is define inside the class as :

Dim _CountBoxVisible as Boolean = True

What I am trying to do is give the user/coder the option to show/utilize the char count feature.  Can make it disappear with textarea1.CharacterCountVisible = False but setting it to true will not make it display.


What am i missing





Category attribute of user control property does not work correctly in categories tab.



I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".

[Category("Styles"), DefaultValue(""), Description("The value for formating something.")]
public String MyFormatProperty
set { /* the code for set */; }
get { /* the code for get */; }

And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.

Does anybody know why? How can I display the category correctly only with set?

Thanks, S.

"Type ASP.x is not defined" error for dynamic user control when publishing updateable


I have a user control (ContainerCtrl) which programmatically instantiates another user control (SimpleCtrl) in OnLoad. It builds and runs fine, but when I publish it I get the error "error BC30002: Type 'ASP.SimpleCtrl' is not defined." (If I publish without the "updateable" option there's no error, but I need the site to be updateable.)

I assume this has to do with the particulars of how the assembly(ies) are built for the different compiler options. My question is, how can I get it to work properly for "updateable" publishing?

VS 2008 / .NET 3.5 sp1

The code follows (web.config is the default from Visual Studio).

Many thanks, Dave


<%@ Control Language="VB" ClassName="SimpleCtrl" CodeFile="SimpleCtrl.ascx.vb" Inherits="_SimpleCtrl" %>

    Simple control


Partial Class _SimpleCtrl
    Inherits UserControl

    'Nothing to see here.

End Class

Types in Yukon: Managed UDTs Let You Extend the SQL Server Type System


The next version of SQL Server, code-named "Yukon," will offer enhanced support for user-defined types (UDTs). Because UDTs can be managed by the CLR, you can represent a wide variety of data structures to create types not possible with previous versions of SQL Server. With UDTs you can more precisely control the kind of data your type accepts, resulting in better data management. This article explores UDTs in "Yukon" and covers their design and implementation.
