如果不使用SelectedIndexChanged，如何從gridview檢索每一行的值？

我有一個GridView, 沒有使用SelectedIndexChanged，我怎樣才能檢索每行從GridView每行的值單擊每行中的每個按鈕？如果不使用SelectedIndexChanged，如何從gridview檢索每一行的值？

這是我的aspx代碼

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ProductID" 
     DataSourceID="SqlDataSource1" ShowHeader="False" AllowPaging="True" BorderColor="White" 
     CellPadding="6" GridLines="None" Height="100px" Width="800px"> 
     <Columns> 
      <asp:TemplateField> 
       <ItemTemplate> 
        Card Name: 
        <asp:Label ID="Label1" runat="server" Text='<%# Bind("Name") %>'></asp:Label> 
        <br /> 
        Cost : 
        <asp:Label ID="Label2" runat="server" Text='<%# Bind("Price") %>'></asp:Label> 
        <br /> 
        <asp:Label ID="Label3" runat="server" Text='<%# Bind("ProductImgID") %>'></asp:Label> 
        <asp:Image ID="Image3" runat="server" ImageUrl='<%# Eval("ProductImgUrl", "images/{0}") %>' /> 
        <br /> 
        <asp:Button ID="btnAddProduct" runat="server" Text="Add" /> 
        <br /> 
       </ItemTemplate> 
      </asp:TemplateField> 
     </Columns> 
    </asp:GridView>

一個選擇可以是綁定的的CommandArgument按鈕轉到ProductID

<asp:Button ID="btnAddProduct" runat="server" Text="Add" CommandArgument='<%#Bind("ProductID")%>' />

然後在RowCommand事件檢索的ProductID，然後使用ID從數據庫中檢索該行從數據庫

string prodID=(string)e.CommandArgument()

提取的行。

爲了得到一個行值，你必須讓行參考，讓該行就可以輕鬆到達指定的列，並能得到數值後

讓我們考慮你在模板字段列中有一個「鏈接按鈕控件」。對於gridview，你必須設置Row Command Event，並且在列的編輯模板中設置鏈接按鈕的命令名稱，也可以稱爲「lnkTest」

在RowCommand事件中，必須包含以下代碼段

if(e.CommandName.Equals("lnkTest")) // Checks that link button was clicked 

    { 
    GridViewRow grdRow = (((LinkButton)e.CommandSource).Container) 

// This Will give you the reference of the Row in which the link button was clicked 

    int grdRowIndex = grdRow.RowIndex; 

//This will give you the index of the row 

    var uniqueDataKeyValue = GridView1.DataKeys[grdRowIndex].Value;

//這會給你的DataKey價值，鏈接控制是點擊

希望行以上代碼將有助於

添加CommandArgument='<%# Container.DataItemIndex %>'到您的添加按鈕

<asp:Button ID="btnAddProduct" runat="server" Text="Add" CommandArgument='<%# Container.DataItemIndex %>'/>

以檢索Name，在gridview行命令使用此代碼

Dim gvr As GridViewRow = grvGRNCONs.Rows(e.CommandArgument) 
Dim name As String = DirectCast(gvr.FindControl("Label1"), Label).Text

等..
