c# - WPF binding properties to Datagrid -

-

I have forced an Observable collection for DataSrid for a Madsource, however, I want to recover the personal properties through a setter (through a setter). See modal

Fine nonsense will be deemed to be frightening by speaking.

In my observation, I have a property called "active", so I want to set this element when a user clicks or closes the checkbox in the datagrid.

XML 

  & lt; DataGridTemplateColumn.CellTemplate & gt; & Lt; DataTemplate & gt; & Lt; Checkbox IsChecked = "{Binding Active, Mode = Two}" Horizontal Alignment = "Center" & gt; & Lt; / Checkbox & gt; & Lt; / DataTemplate & gt; & Lt; /DataGridTemplateColumn.CellTemplate>   
 And I want to trigger this code in ViewModel, when the box is unchecked or checked  
  private bool m_active = false; Public Button Active {get {return m_Active; } Set {m_Active = value; OnPropertyChanged ("Active"); }}   
 But on two-way mode, it's not.  
 Note: I can get selected columns on the SelectedItem property of DataGrid, so basically I want the selected personal property!  
 Thanks   
 
 
 It seems that you are confused where the datagrid 'active' property Is looking for since the datagrid is bound to an observation archive, so the objects inside the viewable archive require 'active' properties, not the visual model used for the scene. If, however, you really want to pair all the rows of a datagrid for a single property on the visual model, you will need to look at the ancestor's tree and then connect it to the 'active' property to find the data reference of the control:  
  & lt; Check box ischhecked = "{binding relative serous = {relative serous FindAncestor, ancestor type = {x: type user control}}, path = data contentbox, active = mode = double}" horizontal alignment = "center" & gt; & Lt; / Check box & gt;   
 But, I imagine, you want to bind this observation archive with the 'active' property of the object. When you are running your application, check your output window and you should see the binding error, if it is not present on the property object

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
