问题 I have a button with binding which works fine, see below: <Button x:Name="licenceFilterSet" Content="Search" Command="{Binding searchCommand}" CommandParameter="{Binding Path=Text, ElementName=licenseTextBox}" /> Now I have realized that I need yet another piece of information, so I need to send the value of a check-box as well. I modified the VM like this: <Button x:Name="licenceFilterSet" Content="Search" Command="{Binding licenseSearchCommand}"> <Button.CommandParameter> <MultiBinding

Multibinding as resource in XAML

[亡魂溺海] 提交于 2019-11-30 14:41:25
Is it possible (if yes how), to add multivaluebinding expression into resource. I have a Multivalue binding, that takes 2 separate binding, and converter parameter in one of those binding. I have to use this binding to 5 Different items, and those binding tags differ only in converter parameter. Rest everything is same. I would to avoid repetition of multibinding boilerplate tags. Easy way of seeing if something works: TRY IT! <Style TargetType="Button"> <Setter Property="Content"> <Setter.Value> <MultiBinding Converter="{StaticResource OmgLolzConverter}"> <Binding Path="One" Converter="

How can I convert the values of three sliders into a Color?

问题 I'm trying to create a custom user control that will allow a user to define a color in WPF. I've done this before in WinForms but in WPF it seems to be not as straight forward. This is also my first time dealing with a multi-converter. The control has 3 Sliders - like so : <Slider x:Name="sdrRed" Height="32" LargeChange="5" SmallChange="1" Maximum="255" Width="321" TickPlacement="Both"/> The only difference is the name for each - sdrRed, sdrGreen, and sdrBlue. This is the multi-value

How can I pass a constant value for 1 binding in multi-binding?

问题 I have a multi-binding like <TextBlock> <TextBlock.Text> <MultiBinding Converter="{StaticResource myConverter}"> <Binding Path="myFirst.Value" /> <Binding Path="mySecond.Value" /> </MultiBinding> </TextBlock.Text> </TextBlock> And I want to pass a fixed value e.g. "123" to one of the two bindings above. How can I do that using XAML? 回答1: If your value is simply a string , you can specify it as a constant in the Source property of a binding. If it is any other primitive data type, you need to

MultiDataTrigger vs DataTrigger with multibinding

戏子无情 提交于 2019-11-30 06:14:34
I encountered a situation where I can easily achieve the same functionality by using a MultiDataTrigger or, alternately, using a DataTrigger with a MultiBinding . Are there any substantive reasons to prefer one approach over the other? With MultiDataTrigger: <MultiDataTrigger> <MultiDataTrigger.Conditions> <Condition Binding="{Binding Path=SomePath}" Value="SomeValue"/> <Condition Binding="{Binding Path=SomeOtherPath, Converter={StaticResource SomeConverter}}" Value="SomeOtherValue"/> </MultiDataTrigger.Conditions> <MultiDataTrigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource

WPF MultiBinding in Convertor fails ==> DependencyProperty.UnsetValue

Generalize guice's robot-legs example with Multibinding

被刻印的时光 ゝ 提交于 2019-11-29 07:12:13
I have this use case that is very similar to the robot-legs example of Guice, except I don't know how many "legs" I have. Therefore I can't use the annotations needed for the robot-legs example. I expect to gather all these "legs" in an java.util.Set with Guice's Multibindings extension. Technically, in a PrivateModule I would like to expose an implementation directly as an element of the set that will be provided by the Multibindings extension. I just don't know how to do that. For reference and code example, see the robot-legs example here: http://code.google.com/p/google-guice/wiki
