在頁面間傳遞一個ID

Question

我有一個Default.aspx頁面，其中我綁定了一個Grid。網格中有一個名爲Details的按鈕。

我也有一個Details.aspx它有一個GridView。如果我點擊Default.aspx中存在的按鈕，將出現一個Details.aspx頁面，該頁面顯示爲空。

單擊特定行的詳細信息按鈕時，會出現該按鈕被點擊的詳細信息。我不知道如何將ID傳遞給Details.aspx。

有人可以指導我這個嗎？

Details.aspx

<asp:GridView ID="DetailsGridView" runat="server" BackColor="White" AutoGenerateColumns="false" 
      BorderColor="#DEDFDE" BorderStyle="None" BorderWidth="1px" CellPadding="4" DataKeyNames="ID" 
      ForeColor="Black" GridLines="Vertical"> 
      <FooterStyle BackColor="#CCCC99" /> 
     <PagerStyle BackColor="#F7F7DE" ForeColor="Black" HorizontalAlign="Right" /> 
     <SelectedRowStyle BackColor="#CE5D5A" Font-Bold="True" ForeColor="White" /> 
     <HeaderStyle BackColor="#6B696B" Font-Bold="True" ForeColor="White" /> 
     <AlternatingRowStyle BackColor="White" /> 
     </asp:GridView> 

的Default.aspx：

  <Columns> 
       <asp:BoundField HeaderText="First Name" DataField="FirstName" /> 
       <asp:BoundField HeaderText="Last Name" DataField = "LastName" /> 
       <asp:BoundField HeaderText="HomePhoneNumber" DataField="HomePhoneNumber" /> 
       <asp:TemplateField HeaderText="ViewDetails"> 
       <ItemTemplate> 
       <asp:Button ID="Deatils" runat="server" Text="Details" /> 
       </ItemTemplate>  

       </asp:TemplateField> 

       <asp:TemplateField HeaderText="Actions"> 
       <ItemTemplate> 
       <asp:Button ID="Modify" runat="server" Text="Modify" /> 
       <asp:Button ID="Delete" runat="server" Text="Delete" /> 

       </ItemTemplate> 
       </asp:TemplateField>     
      </Columns> 


      <FooterStyle BackColor="#CCCC99" /> 
      <PagerStyle BackColor="#F7F7DE" ForeColor="Black" HorizontalAlign="Right" /> 
      <SelectedRowStyle BackColor="#CE5D5A" Font-Bold="True" ForeColor="White" /> 
      <HeaderStyle BackColor="#6B696B" Font-Bold="True" ForeColor="White" /> 
      <AlternatingRowStyle BackColor="White" /> 
     </asp:GridView> 
    </div> 

的JavaScript

<script type="text/javascript"> 
function viewProfile(index) 
{ 
     var GridID = document.getElementById("PersonGridView"); 
     var row=GridID.rows[parseInt(index)+1]; 
     window.open('Details.aspx?coaid'+row); 
} 
</script> 

背後的Default.aspx的代碼：

protected void PersonGridView_RowDataBound(object sender, GridViewRowEventArgs e) 
     { 
      if (e.Row.RowType == DataControlRowType.DataRow) 
      { 
       var DataKeys = PersonGridView.DataKeys[e.Row.RowIndex]; 
       DataKeys.Value.ToString(); 
       var ID = DataKeys["ID"].ToString(); 
       Button btnDetails = (Button)e.Row.FindControl("Deatils"); 
       Button btnModify = (Button)e.Row.FindControl("Modify"); 
       Button btnDelete = (Button)e.Row.FindControl("Delete"); 
       btnModify.CommandName = "Modify"; 
       btnDelete.CommandName = "Delete"; 
       btnDetails.CommandName = "Deatils"; 
       btnDelete.CommandArgument = btnModify.CommandArgument = btnDetails.CommandArgument = string.Format("{0}", ID); 
       btnDetails.Attributes["onclick"] = string.Format("viewProfile({0}); return false;", e.Row.RowIndex); 
      } 
     } 

Answer 1

編輯：我修改我的例子，不使用HyperLink，而是將建立一個LinkButton，可以瀏覽到您的Details.aspx頁面傳遞ID值的查詢字符串：

Default.aspx的：

<asp:TemplateField> 
    <ItemTemplate> 
     <asp:LinkButton CommandName="Details" CommandArgument='<%# Eval("ID") %>' Text="Details" runat="server" /> 
    </ItemTemplate> 
</asp:TemplateField> 

Default.aspx.cs：

protected void PersonGridView_RowCommand(object sender, GridViewCommandEventArgs e) 
{ 
    if (e.CommandName == "Details") 
    { 
     Server.Transfer("Details.aspx?ID=" + e.CommandArgument.ToString()); 
    } 
}

在網格上，當你點擊按鈕

做以下

public protected sub Button_Click(EventArgs e) 
{ 

if (grid.SelectedItem != null) 
{ 

var selectedRow = grid.SelectedItem ; 

// do what ever you want to Selected Row that may be binding it to another Form etc. 
} 

執行相同的OnSelectedEvent，如果你想改爲這樣做。

public protected sub OnSelectedEvent_Click(EventArgs e) 
{ 

if (grid.SelectedItem != null) 
{ 

var selectedRow = grid.SelectedItem ; 

// do what ever you want to Selected Row that may be binding it to another Form etc. 
}
