Example from CSV

CSV files are often used so website-owners can upload data from another system. This example shows us getting the CSV-file through a query and visualizing it here.

Result

@inherits Custom.Hybrid.RazorTyped
@using ToSic.Razor.Blade
@using System.Linq

@{
  // get the query
  var query = Kit.Data.GetQuery("ProductsFromCSV");

  // get the data from the query
  var products = AsItems(query);

  // get the current product or the default - the query always selects one
  var current = AsItem(query.GetStream("Current"));
}
<ul>
  @foreach (var product in products) {
    <!-- this li will have class=selected if it's the current one -->
    <li class='@(product.Equals(current) ? "selected" : "")'>
      <!-- this creates a link to the current page and product=id -->
      <a href='@Link.To(parameters: MyPage.Parameters.Set("product", product.Id.ToString()))'>
        @product.Get("Name") (#@product.Id)
      </a>
      @if (product.Equals(current)) {
        <br>
        <em>
          @current.Get("Description") 
          (<a href="@product.("Link")" target="_blank">find out more</a>)
        </em>
      }
    </li>
  }
</ul>

Get Current Data from CSV

This is similar to the previous example, except that the CSV file can be uploaded again and again in the App-Settings UI. So the path isn't hard-coded.

Result

@inherits Custom.Hybrid.RazorTyped
@using ToSic.Razor.Blade
@using System.Linq

@{
  // get the query
  var query = Kit.Data.GetQuery("ProductsFromCsvInAppSettings");

  // get the data from the query
  var products = AsItems(query);

  // get the current author (if available) from the stream Current
  var current = AsItem(query.GetStream("Current"));
}
<ul>
  @foreach (var product in products) {
    <!-- this li will have class=selected if it's the current one -->
    <li class='@(product.Equals(current) ? "selected" : "")'>
      <!-- this creates a link to the current page and product=id -->
      <a href='@Link.To(parameters: MyPage.Parameters.Set("product", product.Id.ToString()))'>
        @product.Get("Name") (#@product.Id)
      </a>
      @if (product.Equals(current)) {
        <br>
        <em>
          @current.Get("Description") 
          (<a href="@product.Url("Link")" target="_blank">find out more</a>)
