$"{nameof(MDynamicComponent)} does not accept a parameter with the name '{entry.Name}'. To pass parameters to the dynamically-rendered component, use the '{nameof(Parameters)}' parameter."); } } if (Type is null) { throw new InvalidOperationException($"{nameof(MDynamicComponent)} require...
Pass data into a RenderFragment to give it context. Use a CascadingParameter to pass the parent TabControl component into its child TabPage components. 下面看最终效果图: 实操开始: 请先创建一个Blazor项目(Blazor Client或者Server皆可,我们以Blazor Server为例), 第一步,创建两个组件:TabControl和TabPage。
How Blazor interprets the values we pass to the component depends on the type of the [Parameter] we are setting, and whether or not we have made our intentions explicit by use of the @ symbol. Parameters are assigned using the name=value format, just as they are in HTML mark-up. Whet...
不用[Parameter],我们可以这样用[CascadingParameter]: [CascadingParameter] public int MyParameter { get; set; } To pass a value to the component, we surround it with a CascadingValue component like this: <CascadingValue Value="MyProperty"> ...
It renders the layout and passes it the type of the component to add to theBodyRenderFragment. 组件 所有的组件都是普通的实现了IComponent接口的类。 IComponent接口的定义如下: public interface IComponent { void Attach(RenderHandle renderHandle); Task SetParametersAsync(ParameterView parameters); } ...
We've already seen how Blazor allows us to pass context from a parent component to a child using Parameters. As a component becomes more complex it is not uncommon to split it up into sub-components. At some point it is likely a component will require its consumer to pass state that it...
是指在Blazor应用程序中,根据用户的身份和权限动态控制组件的访问权限。通过动态授权,可以根据用户的角色或其他条件来限制用户对特定组件的访问或操作。 Blazor是一个基于WebAssembly的...
Avoid the use ofcatch-all parameters. If catch-all parameters are used, every explicit parameter onDynamicComponenteffectively is a reserved word that you can't pass to a dynamic child. Any new parameters passed toDynamicComponentare a breaking change, as they start shadowing child component param...
The Commands View displays a set of predefined commands, which the user can browse and execute. The commands are passed to the component through theCommandsparameter, which expects a collection of typeList<AIPromptCommandDescriptor>. You can also organize commands in a hierarchy, through parent-chi...
