Changing the values ​​in a DataGrid's Editing Event

I have a datagroup in which a check box Is the column. Only one row can check the check box. If the user checks a new box, all other boxes will be automatically unchecked, similar to a radio button. I have tried to apply that behavior to Row Adiding Event, but if I am modifying the values ​​of the items in this event, the editing is being canceled? That is, the check boxes are left unchanged. If the check box is unchecked, check boxes are updated and editing is usually the code I am using here: 

  Private Zero Grd Q & A Answers_RowEditEnded (Object Sender, System.Windows .Controls.DataGridRowEditEndedEventArgs e) {If (DataGridEditAction.Commit == e.EditAction) {Reply Answer = (Answer) E.R.D. Datacentex; If (Answer is true == true) {foreach (other answer answers in grd Q & A Answers.ItemsSource) {If (other answer! = Answer) {answer.Correct = false; }}}}}

I'm a slob so that if there is a better way of doing this then I have all the ears.

As far as I can tell the "roededet ending" incident, there is no purpose. When it is removed, the values ​​in that row have not been changed yet and you can not see how they will be changed.

"RoediteNDed" might be what you want - I have WPF in this problem and found that WPF is not "RowEditEnded" in DataGrid since I was bound to a DataTable, so I just used DataTable Rook was associated with a chunked event.

In addition to - 

  answer.Correct = false;

should be 

  other Answers.Correct = false;

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.

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
