binding

问题 I'm running OSX(10.4.11) & I'm trying to get a decent C(preferably C++) binding for MySQL figured out. I have some data in an offsite database I want to analyze. I'm trying to get MySQL++ working, but it's being funky. I'm looking for other bindings, preferably ones with a no-headache install. edit: MySQL has C bindings. Clunky and low-level, but it works(after some library fiddling). http://www.sqlapi.com/ supports Solaris/Windows/Linux. 回答1: MySQL Connector/C++ is a C++ implementation of

问题 I have prepared a small jsfiddle here: http://jsfiddle.net/zb8jwre6/ Basically, I have observable array of sliders, and each slider should have it's own observable array of segments, which contain some properties for CSS-binding in HTML. My first problem is that I'am not sure which foreach bind should i use: This one doesn't work for some reason: <div data-bind "foreach: $root.sliders"> <p data-bind="text: day"></p> </div> This one works, but I am not sure in which cases should I use this one

问题 I'm trying to assign DataContext to a MenuItem, which is part of ListBox. <Style x:Key="ContextMenuStyle" TargetType="telerik:RadMenuItem"> <Setter Property="DataContext" Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=telerik:RadListBox}, Path=DataContext}" /> </Style> <DataTemplate x:Key="TemplateSelector"> <ContentPresenter Content="{Binding}" Name="contentPresenter"> <telerik:RadContextMenu.ContextMenu> <telerik:RadContextMenu> <telerik:RadMenuItem Header=

问题 Relatively new to WFP and C# (longtime PHP programmer)... I successfully set up 2-WAY data binding between a TextBox and a Property of an Object. I was able to establish the binding in the Code-Behind, but not do it in the XAML instead. I would like to learn how to do the BINDING in the XAML instead. That is, in the example below, how to move the line myTestPanel.DataContext = CURRENT_NETWORK; from the Code-Behind to the XAML? I looked at tutorials, examples, etc., but none helped... They

问题 I have a pdo statement to select rows and return them in an array. I am using pagination to display 12 results per page. If I directly input LIMIT 12, 12 , instead of LIMIT ?, ? the statement works correctly. What am I doing wrong with the bindParam for both variables? Both variables contain the correct data. Heres the function I'm using: // Retrieve active posts function retrieve_active_posts(){ //test the connection try{ //connect to the database $dbh = new PDO("mysql:host=db2940.oneandone

问题 I have a TextBox which needs to be enabled / disabled programmatically. I want to achieve this using a binding to a Boolean . Here is the TextBox XAML: <TextBox Height="424" HorizontalAlignment="Left" Margin="179,57,0,0" Name="textBox2" VerticalAlignment="Top" Width="777" TextWrapping="WrapWithOverflow" ScrollViewer.CanContentScroll="True" ScrollViewer.VerticalScrollBarVisibility="Auto" AcceptsReturn="True" AcceptsTab="True" Text="{Binding Path=Text, UpdateSourceTrigger=PropertyChanged}"

问题 I am creating a custom button that shows slightly faded text normally, and full-strength text on a MouseOver or MouseDown . I have defined two resources in the Generic.xaml of my control to represent the brushes for these text colors: <!-- Text Brushes --> <SolidColorBrush x:Key="NormalTextBrush" Color="Black" /> <SolidColorBrush x:Key="FadedTextBrush" Color="Gray" /> The control compiles and works fine in that configuration. But I want to let the control user set the text color, using the

问题 I am unable to bind ItemClick from MvxRecyclerView (or its Adapter) to a command on my ViewModel using Fluent API. It works if I put both ItemsSource and ItemClick in the XML so I am not interested in such solution. I used this post as an excellent guideline (How to use the MvvmCross fluent API to bind a RecyclerView item's TextView to a property of its ViewModel on Android?) and all of that works except that I am unable to bind ItemClick on MvxRecyclerView (or the adapter) to a MainViewModel

问题 I have a SQL CE database, which is beyond my control, that has fields in the format of ., complete with a period in the column name. The columns will always be different, so I cannot have a strong-typed data field. I've been tasked with displaying dynamic table data into a DataGrid. Normally, this would be easy -- auto-generate the columns and everything is cool. Easy example. However, I'm not allowed to do this, since the '.' character in the column names nukes the binding. Right now, I'm

问题 In the constructor of my object, I create some span tag and I need to refers them to a method of the same object. Here is an example of my code: $(document).ready(function(){ var slider = new myObject("name"); }); function myObject(data){ this.name = data; //Add a span tag, and the onclick must refer to the object's method $("body").append("<span>Test</span>"); $("span").click(function(){ myMethod(); //I want to exec the method of the current object }); this.myMethod = myMethod; function
