c# - how to refresh wpf data trigger ? -

-

I have the grid down with the storyboard 

   & Lt; DiscreteObjectKeyFrame Keytime = "0: 0: 2" value = "{x: Static Visibility. Collapsed}" /> & Lt; / ObjectAnimationUsingKeyFrames & gt; & Lt; / Storyboard & gt; & Lt; /Grid.Resources> & Lt; Grid.Style & gt; & Lt; Style & gt; & Lt; Style.Triggers & gt; & Lt; Data Trigger Value = "True" Binding = "{Binding Path = Blink Order Alert, Mode = Two}" & gt; & Lt; DataTrigger.EnterActions & gt; & Lt; StartStoreboard x: name = "Stree_ BlinkOrdAlert" Storyboard = "{Static Resources Stree_order Monjshoehide}" /> & Lt; /DataTrigger.EnterActions> & Lt; / DataTrigger & gt; & Lt; /Style.Triggers> & Lt; / Style & gt;   
  
 and in my ViewModel.cs,  
  private bool blinkOrderAlert; Public Bull BlinkOrderAlert {get {return blinkOrderAlert; } Set {if (blinkOrderAlert == value) returns; This.blinkOrderAlert = Value; This.RaisePropertyChanged (this, new PropertyChangedEventArgs ("BlinkOrderAlert")); }} Public Zero BlinkOrdAlert () {this.BlinkOrderAlert = false; This.BlinkOrderAlert = True; } Public ViewModel () {this.BlinkOrderAlert = true; }   
 And it works only for the first time when the constructor is started. Whenever I call the BlinkOrdAlert function, it is no longer working. How can I modify the DataTiger to run the storyboard, whenever I call the function? Thank you.   
 
 
 Consider triggering the following data into style. The following data trigger will remove the story board when the BlinkOrderAlert value is set to false and when the value is correct it will add the story board.  
 Hope this will help.  
  & lt; DataTiger value = "wrong" binding = "{binding path = blink order alert, mode = two}" & gt; & Lt; DataTrigger.EnterActions & gt; & Lt; StartStoryboard Start StoryboardName = "stry_BlinkOrdAlert" & gt; & Lt; / RemoveStoryboard & gt; & Lt; /DataTrigger.EnterActions> & Lt; / DataTrigger & gt;

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

Gatefolder path (environment specialfolder personal), "mydb.db3"); // The following line will be called coolestation, where is the database, // to make it if it does not exist, and call a delegate that creates the necessary tables (only when the database file was newly created //) CSConfig.SetDB (DbName, true, () => {CSDatabase.ExecuteNonQuery ("Subscriber Integer Primary Key Attribute, Name Text (50) No, Number, Date First Text (30)");); There is no difference when I try to use the methods of CSConfig and when I cscfif If I try to pass 3 aggregates to STDB (3) then I get the invalid ...
