collections - Silverlight 3 DataGrid Grouping - Detecting Group Header Click or Header Expand/Collapse -

-

I am using PagedCollectionView in Silverlight 3 for group items in a data grid. I can find out when I click on group headers, but after 6 hours, there can be no way to do this.

(So when a brief title is clicked, I can dynamically load the contents of the group)

The datagrid is populated like this:

PagedCollectionView Collection = New PagedCollectionView (orgMembers); Collection (group). Group (description of new property group ("generation"));

DataGrid1 ItemsSource = Archive;

Type an extension method to search for a specific element of a specific type:

< Pre> Public Static Search FindParentOfType & lt; T & gt; (This framework element element) {var parent = VisualTreeHelper.GetParent (element) as frameworkElement; While (parent! = Zero) {if (original is T) returns (T) (object) parent; Parents = WizardryHelper.GetParent (basic) Framework Element; } Return Default (T); }

Mouse leftbuttonup event handle on the DataGrid: 

  Private Zero passportgrid_MouseLeftButtonUp (Object Sender, MouseButtonEventArgs E) {DataGridRowGroupHeader rgh = (e.OriginalSource FrameworkElement ) .FindParentOfType & LT; DataGridRowGroupHeader & gt; (); If (rgh! = Null & RGH DataContact Collection is ViewGroup) {var stuff = (in the form of collection group. Datacontext); Var items = accessories. }}

You can find information on the group that was clicked and its item archive (shown above)

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...

By using Wordpress I have created a multiple selection box so that users can select categories to exclude. When the page is initially loaded, I see my predefined default option.

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som...
