wpf - Add dependency property to control -

I'm using the Infragistics XamDateTimeEditor control and I want to add a dependency asset to allow developers to select everyone. When the text is controlled, the text is selected then the text is selected. I have created a style that I want to use to set up the behavior, but I want the developer to decide whether the Boolean dependency is the property Base form Behavior should be executed. I'm not sure how this is done.

I inherited this from XamDateTimeEditor for you.

If you refer to the code "standard" (CLR) property, then you are good to go:

1. Announce your dependency
< Li>

Remove your backing field and replace it with standard properties so that it can use dependency properties instead of backing field. Public class MyXamDateTimeEditor: XamDateTimeEditor {public static has been read; DependencyProperty isSelectOnFocusEnabledProperty = DependencyProperty.Register ("IsSelectOnFocusEnabled", typeof (bool) typef (MixedDateTitidator), new UIPpropy metadata (false)); Public Bull ISelectOnFocusEnabled {get {return (bool) GetValue (IsSelectOnFocusEnabledProperty); } Set {SetValue (IsSelectOnFocusEnabledProperty, value); After that, when you use IsSelectOnFocusEnabled in your code, that dependency will return the current property value.

Whenever you change the property, you can install it to receive notification, but I do not know why you want it in your case.

There is another option for this trick, which does not use any heritage and attached property if you wish. Update:

OK, because this request was made, there is a way to get this for a text box here. Whatever event you use, it should be easy to translate it into another type of control.

  public class text boxes behears {public static bool GetIsSelectOnFocus enabled (dependency object obj) {return (bool) obj getValue (IsSelectOnFocusEnabledProperty); } Public Fixed Zero SetIsSelectOnFocusEnabled (dependency object obj, bool value) {obj.SetValue (IsSelectOnFocusEnabledProperty, value); } DependencyProperty.RegisterAttached ("IsSelectOnFocusEnabled", typeof (bool), typef (text boxbyvers), new UIPropertyMetadata (incorrect, new PropertyChangedCallback (OnSelectOnFocusChange)); Dependency Presentation for Public Static Reading Dependency; Private Static Zero On-SetOf Function Change (Dependency Object D, Dependency Property Entrepreneur E) {If (D is Textbox) {var tb = d as Textbox; If ((bool e.NewValue) {tb.GotFocus + = New Routing Avenant (TB_GotFocus); } Other {tb.GotFocus - = new routing and handler (tb_GotFocus); }}} Fixed zero tb_GotFocus (object sender, RoutedEventArgs e) {var tb = sender as text box; Tb.SelectAll (); For example:  
  & lt; Window x: Class = "WpfApplication2.Window1" xmlns = ""   
 http://schemas.microsoft.com/winfx/2006/xaml/presentation "xmlns: x =" http: //schemas.microsoft.com/winfx/2006/xaml "xmlns: local =" clr-namespace: WpfApplication2 "title =" window 1 "height =" 300 "width =" 300 "> Grid & gt; ; & Lt; Grid.ColumnDefinitions & gt; & lt; column expansion width = "*" /> 
 column width = "Auto" /> gt; & lt; /Grid.ColumnDefinitions & amp; gt; Grid .RowDefinitions & gt; RowDefinition Height = "Auto" /> RowDefinition Height = "Auto" /> & lt; /Grid.RowDefinitions>;;;;;;;;;;; *; Text box text = "X: name =" text box 1 "/> & lt; checkbox Ingredient = "auto selection" grid.colom = "1" ischicaked = "{binding path = (local: text box encroachment: ISAclacton focus), elementname = text box 1, mode = two}" /> 
 text Box grid. Line = "1" text = "djkhfskkfdsddsdg" local: textbox BVWeers.yasclactonfocus = "true" /> & Lt; / Grid & gt; & Lt; / Window & gt;  
 
 It shows you how to set up the property to activate the behavior, and how to bind it to do something else if you need it. Note that this specific example is not correct (if you work through this tab, if you click inside the control, then there is an internal argument in the textbox, which in fact unselects the text, but only one example Is how to attach behavior to the control through enclosed properties).
