YngveHestem.GenericParameterCollection.RadzenBlazor 1.0.5

GenericParameterCollection.RadzenBlazor

This provides controls for using GenericParameterCollection in the Blazor by using Radzen.Blazor.

How to use this package

The easiest way to use the package is to download it from nuget: https://www.nuget.org/packages/YngveHestem.GenericParameterCollection.RadzenBlazor.

Initial setup of Radzen

This package uses Radzen, including ToolTip-functionality. This must be set up correctly in the target project. If you are using Radzen already in the project, you will most likely not need to do anything, or eventually very little. See Radzen.Blazor's Getting Started-guide for what you eventually need to do.

Main features/controls

ParameterCollectionView

This is a Blazor-component. This is the main control that handles editing a given ParameterCollection object.

Properties and events

Here is a list of properties and events of the ParameterCollectionView-component.

ParameterCollection

Set this to the ParameterCollection the component should render.

Mark that the component will not automatically update the given ParameterCollection. To get the new value you need to either use the Get of this property, or using the NewParameterCollection-property you get in the OnChange-event.

Options

This property let you set customized Options for how the ParameterCollectionView should look and behave.

OnChange-event

This event is triggered each time the user do a change in the component.

When the event is triggered you will get an object that will contain both the new ParameterCollection, and the key to the parameter that was changed.

Mark: If you use this OnChange-event, you must currently manually set the new ParameterCollection to the ParameterCollection that is referenced in the component before the OnChange-event has exited. If not you may see that Blazor reloads the last version of the ParameterCollection.

CustomParameterComponents

Here you can define a list of custom comonent definitions.

This can be good to use if you for instance want a color picker for picking some colors, or have your own component you want to use for some parameter.

CustomConverters

Do you have some custom converters you need to use for converting some custom value, or want to change how some value is converted in the ParameterCollectionView? Then you can define a list of theese here.

Example code

The example-code below sets the ParameterCollection inside a RadzenCard that also has a heading with the text "Parameters". This is gotten from the TestProject. See that to get even more understanding by how it is used.

<Radzen.Blazor.RadzenCard>
    <Radzen.Blazor.RadzenText TextStyle="Radzen.Blazor.TextStyle.DisplayH2">Parameters</Radzen.Blazor.RadzenText>
    <ParameterCollectionView @ref="_parameterCollectionView" ParameterCollection="@_parameters" Options="@_options" OnChange="@(args => {
                                                                                                                                    _parameters = args.NewParameterCollection;
                                                                                                                                    Console.WriteLine($"{DateTime.Now}: ParameterCollection got update. Parameter updated was {args.ParameterKey ?? string.Empty}.");
                                                                                                                                    })"></ParameterCollectionView>
</Radzen.Blazor.RadzenCard>

Options

The controls let you provide a ParameterCollectionViewOptions. Here you can define some customisation of how the control looks and works. Most are both self explanatory and well documented in code. Most of theese options can also be set for a specific parameter if the option AdditionalInfoWillOverride is set to true (default is true). Then one or more of the given parameters below can be given in a parameters additionalInfo.

Different options

Here is a list of parameters that can either be defined in ParameterCollectionPanelOptions or as a ParameterCollection (some can only be given in one, while many can be given both ways).

If you define this in a ParameterCollection-ParameterType, the changes will affect all parameters in that ParameterCollection.
