c# - Xamarin 从数据模板中的标签中提取文本（列表视图）

问题描述

我想从标签 id 中获取文本以在单击供应商时查询新负载


private async Task InitAsync()
        {


            RestAPI rest = new RestAPI("http://azipit.co.za/mica-market-app/wp-json/wc/v3/", "ck_0112f135e2fxxxxxxd621f919bc890", "cs_38ea21f4d63xxxxxxxxxx1868993b66065dcb0362fa");
            WCObject wc = new WCObject(rest);
            var products = await wc.Tag.GetAll();
            var p = await wc.Tag.GetAll(new Dictionary<string, string>() {

                    { "per_page", "80" } }); ;


            productsListView.ItemsSource = p;



        }

        async void retrieveid()
        {

        }



        async void SupplierClicked(object sender, EventArgs args)
        {


            RestAPI rest = new RestAPI("http://azipit.co.za/mica-market-app/wp-json/wc/v3/", "ck_0112f135e2f9b32cc14xxxxxxxxxxxx919bc890", "cs_38ea21f4d63exxxxx01868993b66065dcb0362fa");
            WCObject wc = new WCObject(rest);
            var products = await wc.Product.GetAll();
            var p = await wc.Product.GetAll(new Dictionary<string, string>() {
                {"tag" , tagid },
                    { "per_page", "80" } }); ;

            productsListView.ItemsSource = p;


        }

                    </DataTemplate>
                </ListView.ItemTemplate>
            </ListView>
        </StackLayout>
    </ContentPage.Content>
</ContentPage>

我不知道如何从“标签”中获取 ID，在这种情况下这是我的供应商，以便我可以查询以加载它下面的产品，所以我的逻辑是尝试使用 ax:Name 并从标签为正确加载它们

对此有任何建议或可能的解决方法吗？

期望的结果：单击供应商处的按钮，它会加载该标签下的每个产品。

标签： c#xamlxamarinwoocommerce

解决方案

按钮的BindingContext将是对该行相关项目的引用

protected void SupplierClicked(object sender, EventArgs a)
{
  var btn = (Button)sender;
  var product = (Product)btn.BindingContext;

  // now you can reference any property of Product that you need
}
