从转发器中检索值 [英] Retrieving a value from a repeater

问题描述

大家好，



我正在尝试从转发器中检索一些数据，最终目标是将一堆数据发送到表中。



我使用以下内容访问转发器，但FindControl有下划线：

  String  prodName =（（Literal）Repeater1.ItemTemplate.FindControl（  LitProdName））。文字; 

但是我收到警告：

 错误  1  '  System.Web.UI.ITemplate'不包含'FindControl'的定义并且没有扩展方法'FindControl'接受类型为'System.Web.UI.ITemplate'的第一个参数'（您是否缺少using指令或程序集引用？）C：\ Users \ User \Desktop \\ \\ WLL \ WLL\ProductDetails.aspx.cs 62 68 WLL  

完整的方法如下s：

  public   void  AddToBasket（）
 {
 
 {
  //   String prodName =Test;  
  String  prodName =（（Literal）Repeater1.ItemTemplate.FindControl（  LitProdName））。文字; 
 字符串 prodID = Request.QueryString [ 的productID]; 
  String  userName = User.Identity.Name; 
 字符串 size =   17.5; 
  int  price =  10 ; 
 
 {
  var  basket =  new  Basket（）; 
 
 basket.User = userName; 
 basket.ProductID = Convert.ToInt32（prodID）; 
  //   basket.ProductName = prodName;  
 basket.Size = size; 
 basket.Price = price; 
 
 使用（ProductContext _db =  new  ProductContext（））
 {
 
 
 _db.Baskets.Add（basket）; 
 _db.SaveChanges（）; 
} 
} 
} 
} 

解决方案

请阅读这个 [ ^ ]了解如何访问模板内的控件...

FindControl 一次适用于一行/项目。



参考 - RepeaterItem.FindControl方法 [ ^ ]。

Hi all,

I'm trying to retrieve some data from a repeater, the end goal is to send a bunch of data in to a table.

I'm using the following to access the repeater, however "FindControl" is underlined:

String prodName = ((Literal)Repeater1.ItemTemplate.FindControl("LitProdName")).Text;

However I get the warning:

"

Error   1   'System.Web.UI.ITemplate' does not contain a definition for 'FindControl' and no extension method 'FindControl' accepting a first argument of type 'System.Web.UI.ITemplate' could be found (are you missing a using directive or an assembly reference?)   C:\Users\User\Desktop\WLL\WLL\ProductDetails.aspx.cs    62  68  WLL

"

The complete method is as follows:

public void AddToBasket()
        {

            {
                //String prodName = "Test";
                String prodName = ((Literal)Repeater1.ItemTemplate.FindControl("LitProdName")).Text;
                String prodID = Request.QueryString["productID"];
                String userName = User.Identity.Name;
                String size = "17.5";
                int price = 10;

                {
                    var basket = new Basket();

                    basket.User = userName;
                    basket.ProductID = Convert.ToInt32(prodID);
                    //basket.ProductName = prodName;
                    basket.Size = size;
                    basket.Price = price;

                    using (ProductContext _db = new ProductContext())
                    {

                      
                        _db.Baskets.Add(basket);
                        _db.SaveChanges();
                    }
                }
            }
        }

解决方案

Please read this[^] to understand how to access controls inside a template...

FindControl works for one Row/Item at a time.

Refer - RepeaterItem.FindControl Method[^].
