I have table like showed below. I want to check/uncheck (for now just trying out check) values in the table based on the type I select. Could this be done somehow like this? Or do I somehow need to send request from javascript to see updated values? Or could this be done by using C# only?

What I have tried:

function selectType(items, type) {
  return items.select(x => x.ObjectType === type).map(x => x.Checked = true);
}


var list = JsonConvert.SerializeObject(@table);
          <form asp-controller="Consumer" asp-action="" method="post">
              <div class="row justify-content-end" style="margin-top: 20px; margin-bottom: 20px;">
                  @foreach (var type in ObjectTypes.All)
                  {
                      <label style="margin-right: 10px;">
                          <input onclick="selectType(@list, @type)" style="margin-right: 5px;" type="checkbox" id="@type" name="type" value="@type">@type
                      </label>
                  }
              </div>
              <table class="table table-striped">
                  <thead>
                  <tr>
                      <th>#</th>
                      <th></th>
                      <th>Object Id</th>
                      <th>Object type</th>
                  </tr>
                  </thead>
                  <tbody>
                  @if (table.Count > 0)
                  {
                      @for (int i = 0; i < table.Count; i++)
                      {
                          <input type="hidden" name="@("items[" + i + "].ObjectId")" value="@table[i].ObjectId"/>
                          <input type="hidden" name="@("items[" + i + "].ObjectType")" value="@table[i].ObjectType"/>
                          <tr>
                              <td>@(++id)</td>
                              <td>
                                  <input name="@("items[" + i + "].Checked")" type="checkbox" value="true" @(table[i].Checked ? "checked" : " ")/>
                              </td>
                              <td>@table[i].ObjectId</td>
                              <td>@table[i].ObjectType</td>
                          </tr>
                      }
                  }
                  </tbody>
              </table>
          </form>

1 solution

Maybe the form collection is a solution:

var selectedKeys = Request.Form.Keys.Where(k=> k.EndsWith(".Checked", System.StringComparison.OrdinalIgnoreCase));


Returns:
1.Checked
3.Checked
