TreeView in wpf ... Is there a SelectedItemChanging event? -

-

मैं एक सिस्टम का उपयोग कर रहा हूँ। Windows.Controls.TreeView एक wpf अनुप्रयोग में।

असल में मुझे एक SelectedItemChanging ईवेंट के समतुल्य की आवश्यकता है ताकि मैं ट्रीदृश्य की चयन इवेंट को रद्द कर सकता हूं।

क्या ऐसा करने का कोई तरीका है? मैं किसी ट्रीव्यूव्यूज पर चयनित ईट्स-चेंजिंग इवेंट को ढूंढने में सक्षम नहीं था।

धन्यवाद!

< P> मुझे कैसे करना है पर एक लेख मिला।

आप चयनित लेख में ChangedPropertyChangedEventArgs के NewValue और OldValue सदस्यों के संयोजन के साथ उस लेख की तकनीकों का उपयोग कर सकते हैं।

paypal - How to know the URL referrer in PHP? -

-
I'm new to integrating PayPal with sites, so easily from the service I can use Can the available method be? What am I trying to do, when the user clicks on "Return to my website", I want my return URL to know that the referrer is PayPal so I can send it automatically to the homepage . how to do this? I tried $ _ SERVER ['HTTP_REFERER'] but it does not seem like anything. During the IPN conversation I set the cookie and session (though I am not sure whether I am correcting it or doing this right), but on returning to my website, it does not seem to recognize any session . If I use it by using $ _ SERVER ['HTTP_REFERER'] , then I'm afraid it's a security risk, is not it? If so, is there any other way I remember? help please. Should you really know the referrer? Set the PayPal Return URL to a "secret" URL which is always redirected to the homepage. If someone reaches there and gets redirected without coming from PayPal, then ...

oauth - Facebook OAuth2 Logout does not remove fb_ cookie -

-
This is used to work so I'm not sure what's wrong the user just logs in to Facebook properly Is capable of Logging problem. I log out the user logout by redirecting them to the php script. $ facebook-> GetLogoutUrl (); When users click on that link, they are logged out from the Facebook page. However, when they return to my site, I find that the FB_ cookie is still there. PHP SDK still gives user FB session details. The strange thing is that www.facebook.com shows that I am already logged out of Facebook. What can be wrong here? Thanks, I've been stumped: (. OK, finally, what did I do? > GetLogoutUrl () with a next = address url on my logout script which will remove the Facebook cookie by setSession (null) .

wpf - Line breaks and indenting for the XAML of a saved FlowDocument? -

-
Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...
