如何使我的GridView中的鏈接單擊一下？

Question

第1步： - 點擊更多

步驟2： - 單擊添加到購物車將項目添加到購物車

這是我的GridView

    </asp:SqlDataSource> 

這是代碼後面加入購物車鏈接按鈕

Protected Sub GVAddToCart_Click(ByVal sender As Object, ByVal e As System.EventArgs) 
     If User.Identity.Name = "" Then 
      MsgBox("You need to login first before adding anything to the cart!", , "") 
      Response.Redirect("~/login.aspx", True) 
      Exit Sub 
     End If 

     Dim sCart = New cart 
     Dim itemName, GVPrice, offer As Label 
     Dim userID, buyNo, itemID As String 

     itemID = Request.QueryString("itemID") 
     itemName = CType(ListView1.Items(0).FindControl("itemName"), Label) 
     userID = User.Identity.Name 

     Dim index As Integer = GridView1.EditIndex 
     GVPrice = CType(GridView1.Rows(index).FindControl("price"), Label) 
     GVPrice.Text = CType(GVPrice.Text, Integer) 
     offer = CType(GridView1.Rows(index).FindControl("offer"), Label) 

     If sCart.CheckIfItemPresent(userID, itemID, GVPrice.Text, offer.Text) = True Then 
      Exit Sub 
     End If 

     buyNo = sCart.findLatestBuyNo(userID) 
     Session("buyNo") = buyNo 

     Session("buyNo") = sCart.AddToCart(itemID, itemName.Text, GVPrice.Text, offer.Text, buyNo, userID) 
    End Sub 

所以我想要做的是刪除第1步..如何才能做到這一點？

如果我刪除更多的鏈接..它停止工作...請幫助我。

我必須點擊更多鏈接才能獲得添加到購物車的鏈接...我想添加一個項目到購物車中點擊一下..我現在有...我需要兩次點擊。

當我點擊更多它進入編輯模式..然後，當我點擊添加到購物車（這是在編輯模板）..它採取價格和提供編輯模板的值..如果我移動「添加到購物車」按鈕進入ItemTemplate ...它不能訪問報價和價格值。如果我將「添加到購物車」按鈕移動到ItemTemplate中，我將如何知道哪一行正在被點擊？

Answer 1

通過您的描述「刪除第1步」，它聽起來像你想要的鏈接/按鈕字段顯示爲添加到購物車一直。

建議創建一個ButtonField而不是您的ItemTemplates和EditItemTemplates。看起來你不需要編輯功能，而只是一種訪問行中這些屬性的方法。

<asp:GridView OnRowCommand="GridView_RowCommand"> 

    <asp:ButtonField buttontype="Link" 
         commandname="Add" 
         text="Add to Cart"/> 

     <asp:BoundField datafield="itemName" headertext="Item"/> 
     <asp:BoundField datafield="itemPrice" headertext="Your Price"/> 
     <asp:BoundField datafield="shopName" headertext="Shop Name"/> 
     ..... etc. 

代碼隱藏將需要改變，像這樣：

Sub GridView_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs) 

    If e.CommandName = "Add" Then  
     Dim index As Integer = Convert.ToInt32(e.CommandArgument) 
     Dim row As GridViewRow = GridView1.Rows(index) 

     Dim itemName As String = Server.HtmlDecode(row.Cells(1).Text) 
     Dim itemPrice As String = Server.HtmlDecode(row.Cells(2).Text) 
     '...... etc 
     'All required business logic to add to cart. 
    End If 

    End Sub
