Poll System

CMS kit provides a poll system to allow users to create, edit and delete polls. Here is a screenshot of the poll widget:

Enabling the Poll System

By default, CMS Kit features are disabled. Therefore, you need to enable the features you want, before starting to use it. You can use the Global Feature system to enable/disable CMS Kit features on development time. Alternatively, you can use the ABP Framework's Feature System to disable a CMS Kit feature on runtime.

Check the "How to Install" section of the CMS Kit Module documentation to see how to enable/disable CMS Kit features on development time.

User Interface

Menu Items

CMS Kit module admin side adds the following items to the main menu, under the CMS menu item:

Polls: Poll management page.

CmsKitProAdminMenus class has the constants for the menu item names.

Pages

Polls

You can list, create, update and delete polls on the admin side of your solution.

Poll Widget

The poll system provides a poll widget for users to vote and show the result. You can place the widget on a page like the below:

@await Component.InvokeAsync(
    typeof(PollViewComponent),
    new
    {
        widgetName = "my-poll-1"
    })

Options

Before using the poll system, you need to define the widgets. You can use the CmsKitPollingOptions. CmsKitPollingOptions can be configured in the domain layer, in the ConfigureServices method of your module.

Example:

Configure<CmsKitPollingOptions>(options =>
    {
        options.AddWidget("my-poll-1");
    });

CmsKitPollingOptions properties:

• WidgetNames: List of defined widgets in the poll system. options.AddWidget method was a shortcut to add a new widget to this list.

Table / collection prefix & schema

All tables/collections use the Cms prefix by default. Set static properties on the CmsKitDbProperties class if you need to change the table prefix or set a schema name (if supported by your database provider).

Connection string

This module uses CmsKit for the connection string name. If you don't define a connection string with this name, it fallbacks to the Default connection string.
