Binding UserControl property to Page property

Visibility property is a very powerful and yet often overlooked property available in both WPF and Silverlight. It enables you to set Visibility of certain UIElement objects to different states like: Visible, Collapsed and Hidden (not supported by Silverlight). This tutorial shows you how to use it and how to bind to Visibility property

Hello,I have a class that is a base class for my server controls. Inside this class I have a property that can take values from an enumeration.public enum PanelModeEnum { Add = 1, Edit = 2, ReadOnly = 3 } public class BaseControl : System.Web.UI.UserControl { #region Event Handling Management #endregion public PanelModeEnum PanelMode { get; set; } public virtual void ChangePanelMode(PanelModeEnum newMode) { this.PanelMode = newMode; } } I have then several user controls that inherits from this BaseControl and that I add into aspx pages declaratively<gsl:PhoneNumberUC ID="ucPhoneDetail" runat="server" PhoneNumberType="Home" />I would like to show one the derived BaseControl classes inside a ModalPopupExtender using server-side code. Before doing this I call the ChangePanelMode with a value from the PanelModeEnumucPhoneDetail.PhoneNumberType = ptype; ucPhoneDetail.ChangePanelMode(PanelModeEnum.Add); this.mpePopupPhone.Show(); But when, inside the inherited user control I check for the PanelMode property likeif (this.PanelMode == PanelModeEnum.Add) { ... } the value of this.PanelMode is always equal to zero. Why?Kindly regards

Hi... I have defined a UserControl wich needs to reference another control like this: <ctrl:Cook TheList="listView1" DefaultFileName="MyRecipe"></ctrl:Cook> The code behind of the control has the property defined:         public ListView TheList { get; set; } But I have a runtime error saying: 'ListView' type does not have a public TypeConverter class. And in design time I get: Property TheList of type ListView cannot be specified as string.   I know WPF is trying to read a string instead of a ListView, but dont know the magic solution. Maybe a converter? Please suggest the simpler solution you can, because this is not a vital requirement on the app. Thanks in advance for any help  

I have created a custom activity, when I am using this activity in workflow designer I am not getting the ellipsis button to select a property.  I am getting the ellipses button for first property LongValue while not getting the option for "NavigationUrl" property. This is the code for my custom activity. public partial class SetLongAsResult: Activity {         public SetLongAsResult() { InitializeComponent(); }         public static DependencyProperty LongValueProperty = DependencyProperty.Register("LongValue", typeof(long), typeof(SetLongAsResult));           public static DependencyProperty NavigationUrlProperty = DependencyProperty.Register("NavigationUrl", typeof(string), typeof(SetLongAsResult));           [Description("long value to be returned")]         [Category("Set Result Data")]         [BrowsableAttribute(true)]         [DesignerSerializationVisibilityAttribute(DesignerSerializationVisibility.Visible)]         public long LongValue         {             get             {         

So if I had a style as follows <Style TargetType={x:Type Button}> <Setter Property="Background" Value={Binding myproperty} /> </Style> How could I achieve this in code? So far I got Style x = new Style(); Setter a = new Setter(TextBox.Property, new Binding("myproperty")l but there seems to be something wrong with the way I set up the binding, how can I correct it? Thanks

This Gives me an error..   <Style x:Key="radioButtonSelctionKey" TargetType="{x:Type RadioButton}">       <Style.Triggers>       <DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type UserControl}},Path=ValueText}" Value="{Binding Path=Content}">       <Setter Property="IsChecked" Value="True"></Setter>       </DataTrigger>       </Style.Triggers>       </Style> Is it valid to bind Value Property. If not then does it mean that the Value propety must always fix and can not be changed or Bound to any property Dose it mean that both of the way of setting Value proeprt are WRONG..? 1) Value="{Binding Path=Content}"> Or 2) Value="{Binding RelativeSource={RelativeSource Mode=Self},Path=Content}">

Hi, I am not sure how to pass a variable from an .aspx page to an .ascx page.  I have a Control that puts rotating banners on a page.  The control has several public properties.  However, only one of those properties changes on the page level.  All the other properties are the same for every page site-wide.  So, instead of setting all the properties on every page in my sites (many sites), I want to set it up so I only have to setup the sitewide properties once and only the page level properties on each page.   I want to create a control with a property of AdKeyword="somename" and pass it to another control that will grab that page-level property and add it to all the other site-wide properties.  I guess what I need could be called a Dynamic Control Property.   My .aspx page has:<%@ Register TagPrefix="uc1" TagName="Banner1" Src="banner1.ascx" %> <asp:Content ID="Leaderboard" runat="server" ContentPlaceHolderID="Leaderboard"> <uc1:Banner1 AdKeyword="L2Chamber" runat="server" OverrideHeight="90" /> </asp:Content> My banner1.ascx page has:<%@ Control Language="VB" ClassName="UserControl297" %> <%@ register tagprefix="uc1&

Hi  I've got a web site that has a master page and that master page (mpMaster that has a user control (ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page and on this page I have another user control (ucPageControl), I need to  find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all? Many thanks Ed

I am attempting to accomplish the following during the creation of a Page derived from DerivedPage: <local:DerivedPage xmlns="..." xmlns:x="..." xmlns:local="..." MyProperty="My Value" Title="My Title"> ... </local:DerivedPage> You'll notice an extra property MyProperty in there. The code-behind is like this: class DerivedPage : Page { public string MyProperty { get; set; } ... } When I execute this, I get a null reference in InitializeComponent() when I create a Page derived from DerivedPage. I also tried making MyProperty a dependency property.  But I get the same results. How can I create a property for my new base-class that's set in the markup of my derived class. Thanks, ...Matt
