Silverlight Datagrid scrolling, DataGrid fires RowLoading event
The RowLoading event is fired because rows are virtualized. With virtualization, rows are created (and loaded) only when they are visible on screen. So every time you scroll down or up a new row is created, loaded and the RowLoading event fired. To disable the virtualization you can try to set this property: VirtualizingStackPanel.VirtualizationMode="Standard" Be aware that this can slow down the performance of your grid if you have a lot of rows.

DataGrid edition 'EditItem' is not allowed for this view` when bound to a WPF DataGrid
I tried this and the problem is that you have initialized your Level2 collection as Hashset<>. IEditableCollectionView.EditItem() throws this error while trying to update item in Hashset<>. I initialized the collection as List<> and it was working fine. I am not sure why it is not able to update item in hashset, need to look deeper into it. But changing the Hashset<> to List<> will fix this error. Hope it helps Thanks

Binding ComboBoxColumn to collection from DataGrid's ItemsSource in WPF DataGrid
MSDN: DataGridComboboxColumns says: To populate the drop-down list, first set the ItemsSource property for the ComboBox by using one of the following options: A static resource. For more information, see StaticResource Markup Extension. An x:Static code entity. For more information, see x:Static Markup Extension. An inline collection of ComboBoxItem types. So basically to just bind to data object`s collection property it`s better to use DataGridTemplateColumn: <DataGridTemplateColumn Header="Log"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <ComboBox ItemsSource="{Binding log}" /> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn> This type of c

Validating A WPF Datagrid Against Data From Another Datagrid
From Microsoft official WPF course materials: ValidationRules are only to be used as simple validations (For instance Required fields, numeric formats, etc).

A question mark URL encodes as %3F. But you should use a proper encoder for the whole thing rather than manually encoding a specific character. Depending on the server-side technology you're using to build the Urls, tyhere should be a function like UrlEncode() which should handle all this for you. Failing that, Javascript has encodeUriComponent()

How can embed datagrid in datagrid
I don't think it's possible. You can indeed manually replace a cell with the HTML of another grid (your "child" grid), but Dojo maintains its data in a store. Your store won't be "aware" of any changes you make in the DOM nodes of your grid, and inserting a DataGrid in a store isn't possible either since the DataGrid maps its columns to properties of the data objects.

mod rewrite question mark and ampersands
I think the issue here is that in your RewriteRule you're trying to match a part of the query string, which isn't possible. If I understand your problem correctly, you want requests to http://example.com/category/general?type=pages&v=1 to be interpreted by the server as http://example.com/category.php?c=general&type=pages&query=1? To match a query string, you need to prefix your rule with a condition. The following should work: RewriteCond %{QUERY_STRING} type=([^&]+) RewriteCond %{QUERY_STRING} v=([^&]+) RewriteRule ^category/([^/]+) /category.php?c=$1&type=%1&query=%2 The first two lines are pre-conditions that state that the requested URL needs to have both type= and v= as part of the query string. The final line rewrites the request. This means that

What to do with Question Marks in HTAccess Redirects
If it's a single link you want to change you don't need a htaccess rule for that you can just do a redirect. redirect 301 /wordpress/?p=250 http://www.othersite.com/blog If the URL parameter changes you can use this rule. RewriteEngine on RewriteRule ^wordpress/(.*) http://www.othersite.com/blog [R=301,QSA,NC,L] Note that when you use the QSA flag it will append the URL with the query parameter so if that's what you want the resulting URL will be. http://www.othersite.com/blog?p=250 Otherwise if you remove the QSA flag, then it will just redirect to this http://www.othersite.com/blog

hr content shows question mark
The probable explanation is that although the HTML document is declared to be UTF-8 encoded, it actually isn’t. It might be windows-1252 encoded, and when the windows-1252 encoded representation of “§” is encountered when processing presumed UTF-8 data, it constitutes a character data error. A common, and recommended, way in which browsers indicate the error is “�” REPLACEMENT CHARACTER. To fix this, make sure the declared and actual character encoding match. It is less relevant which encoding you use, but other things being equal, it is best to use UTF-8. So you would need an editor or other authoring tool that can actually save the data as UTF-8 encoded. If you absolutely cannot fix the encoding issue, replace "§" in CSS by the escape notation "A7". Much less readable, bu

Can't read a file that contains a question mark in name
As long as the file exists, there is no problem opening a file like this: folder_file = './temp directory/file-?.txt' File.open(folder_file, 'r').close This works fine. See Tin Man's suggestion about how to actually open the .tif file. As you can see, I created the following file myster-file_char?.txt $: ls get_listing.rb myster-file_char?.txt You can get this stored in a variable, though I only use Dir.glob here to view it. puts Dir.glob("**.*").inspect Everything is now revealed in what character it is. Though I should be able to use it directly as is to open and edit the file in Ruby. Though like The Tin Man stated, you are asking about a binary file. $: ruby get_listing.rb ["myster-file_charu0016.txt", "get_listing.rb"] The character that is actually there is a CTRL

What may cause question marks instead of non-ASCII symbols?
You need to change the character set of the database to UTF-8 or a character set for Cyrillic characters. Latin-1 can't encode Cyrillic characters and that's why they're appearing as question marks in the database. edit: I just saw you're declaring the table with UTF-8 character set, so I'm stumped.

Charset converting to question mark with diamond even though utf-8
These are two questions, so two answers: The only logical answer to your problem displaying �, is that somewhere along the line, you are not correctly storing this as UTF-8 and it did get converted to something else. The second problem, (fatal error in eval()'d code.) You should post the code that's triggering this error and preferably not even use eval for anything remotely important. Especially not dynamic eval() code, which you appear to be doing.

What does the ? (backslash question mark) escape sequence mean?
? in regex is a quantifier, it means 0 or 1 occurences. When appended to the + or * quantifiers, it makes it "lazy". For example, applying the regex o? to the string foo? would match o. However, the regex o? in foo? would match o?, because it is searching for a literal question mark in the string, instead of an arbitrary quantifier. Applying the regex o*? to foo? would match oo. More info on quantifiers here.

Rewrite Urls with question mark and ampersand
Ok, assuming the file handling the queries is index.php and foo and bar don't change to something else, you could start like this: RewriteEngine On RewriteBase / RewriteRule ^foo$ foo/ [NC,R] RewriteRule ^foo/$ index.php?foo [NC,L] RewriteRule ^foo/([A-Za-z0-9_-]+)$ foo/$1/ [NC,R] RewriteRule ^foo/([A-Za-z0-9_-]+)/$ index.php?foo&group=$1 [NC,L] Now you should be able to do the bar part on your own! Btw. if you really want your query string to only be ?foo (without a value, like so: ?foo=somevalue) you'll have to check for foo's existence differently than you would for e.g. the somegroup part.

How do I create URL's in ASP.NET Web Forms without the question mark for querystrings?
You do not have to convert entire application to MVC just for the sake of pretty URL. You can easily achieve it by using urlrewriter. Something like this in web.config - <rewriter> <rewrite url="~/Product/(d+)" to="~/default.aspx?productID=$1"/> </rewriter> Note: I did not test the above code. I hope you get the idea. If your application uses .Net 4.5, you might also want to look at URL Routing of ASP.Net.

mapping for question mark for backwards search
Due to the way that the keyboard input is handled internally, this unfortunately isn't generally possible today. Some key combinations, like Ctrl + non-alphabetic cannot be mapped, and Ctrl + letter vs. Ctrl + Shift + letter cannot be distinguished. (Unless your terminal sends a distinct termcap code for it, which most don't.) In insert or command-line mode, try typing the key combination. If nothing happens / is inserted, you cannot use that key combination. This also applies to <Tab> / <C-I>, <CR> / <C-M> / <Esc> / <C-[> etc. (Only exception is <BS> / <C-H>.)

Personally I will use a find by with a in condition such as: Klass.find_all_by_column([1, 2, 3]) Replace 'column' with column name you wish to search in. Replace 1,2,3 by your value, it's an array you can add or remove values from it. My example will generate a SQL query such as: SELECT * FROM Klass WHERE Klass.column IN (1,2,3) More on this on Active record documentation.

Categories : PHP

Arabic turn to strange Question marks
Looking at your screen shot it looks as though you already have some unicode data but as I rough top-down walk through. You should be using nvarchar to store your strings as it is unicode it will record Arabic or extended characters without issue. You also need to check that your character encoding is setup (UTF8 is usually a good bet) and passed through all various places correctly. If you are using SqlConnection and SqlCommand then it would be best to pass the value as a parameter to ensure that everything is being handled correctly and avoid injection attacks. If you are using Entity Framework there should be no additional steps to my knowledge.
