c# - WPF basic binding -

-

I know that it has been asked many times but no matter how many tutorials I read, I can not understand it . I have a three column defining grid that can be resized through two grid spplers. What I need is another grid with three errors below which size changes because the size of the top grid is changing (UI is very similar in programs like iTunes). The reason I want a separate grid is because ultimately, each grid will be its own object and the qualities will need drag and drop. Written here is Xaml, if someone wants to see me what I am looking for. 

  & lt; Canvas width = "400" height = "15" background = "antique white" & gt; & Lt; Grid horizontal alignment = "statch" vertical alignment = "statch" width = "400" name = 'mairidrid' & gt; & Lt; Grid.ColumnDefinitions & gt; & Lt; Column width = "140" minwid = "50" /> & Lt; Column width of width = "116" minway = "50" /> & Lt; Column width = "144" minwath = "50" /> & Lt; /Grid.ColumnDefinitions> & Lt; Grid.RowDefinitions & gt; & Lt; Roadfinion height = "15" /> & Lt; /Grid.RowDefinitions> & Lt; GridSplitter Grid Column = "0" horizontal alignment = "true" vertical alignment = "statch" background = "black" show preview = "true" width = "2" /> & Lt; GridSplitter Grid Column = "1" horizontal alignment = "true" vertical element = "statch" background = "black" show preview = "true" width = "2" /> & Lt; TextBlock Text = "Song" Grid. Column = "0" width = "30" /> & Lt; TextBlock Text = "Song" Grid. Column = "1" width = "30" /> & Lt; TextBlock Text = "Song" Grid. Column = "2" width = "30" /> & Lt; / Grid & gt; & Lt; / Canvas & gt; & Lt; Canvas width = "400" height = "15" background = "roza brown" margin = "58,168,59,138" & gt; & Lt; Grid horizontal alignment = "statch" vertical alignment = "statch" width = "400" & gt; & Lt; Grid.ColumnDefinitions & gt; & Lt; Column width = "140" minwid = "50" /> & Lt; Column width of width = "116" minway = "50" /> & Lt; Column width = "144" minwath = "50" /> & Lt; /Grid.ColumnDefinitions> & Lt; Grid.RowDefinitions & gt; & Lt; Roadfinion height = "15" /> & Lt; /Grid.RowDefinitions> & Lt; TextBlock Text = "Song" Grid. Column = "0" width = "30" /> & Lt; TextBlock Text = "Song" Grid. Column = "1" width = "30" /> & Lt; TextBlock Text = "Song" Grid. Column = "2" width = "30" /> & Lt; / Grid & gt; & Lt; / Canvas & gt; Apart from this, as a last note, I have seen endless tutorials and guides for data binding, and in my 17-year-old brain, I just can not wrap my head around it. . If I could understand how to create a text block, my C # code is bound to one variable in the code (alias: not setting the text property of the text in the text, but only changing the content of a string), then I can do a lot more productive Thanks to me, anyone who can help me, I know that this question has been asked millions of times.   
 
 
 Build your C # codehehind, a property:  
  private string _qultitle; Public string SongTitle {get {return _songTitle; } Set {songTitle = value; }}   
 In your xaml, create bindings:  
  & gt; Text block text = "{binding songtitle}" />   
 Set up the datacentax for your binding (you can put it in the  Window.Loaded  event)  
  this.DataContext = This;   
 Set your property in your code  
  SongTitle = "Some words and stuff";   
 This is about it, it can be more complex, but it is the basics.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
