Answer 1

這不能做 - 當你在頁面一，其餘頁面不是實際存在。

當您要求選擇所有複選框意味着您所看到的。更改頁面後，其他複選框設置爲默認（可能未選中）

因此，重新設計您的用戶界面，爲您贏得了勝利。

Answer 2

這可以用一個調整來完成，這是GridView控件，轉換本作列表視圖或任何其他中繼控制

GridView的HTML

<asp:GridView ID="GridView1" runat="server" 
AutoGenerateColumns="False" AllowPaging="True" 
PageSize="5" Width="324px" DataKeyNames="CategoryID" 
OnPageIndexChanging="GridView1_PageIndexChanging"> 
<Columns> 
<asp:BoundField DataField="CategoryID" HeaderText="CategoryID" /> 
<asp:BoundField DataField="CategoryName" HeaderText="CategoryName" /> 
<asp:TemplateField HeaderText="Select"> 
<ItemTemplate> 
<asp:CheckBox ID="CheckBox1" runat="server" /> 
</ItemTemplate> 
</asp:TemplateField> 
</Columns> 
</asp:GridView> 

CS代碼

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) 
{ 
    RememberOldValues(); 
    GridView1.PageIndex = e.NewPageIndex; 
    BindData(); 
    RePopulateValues(); 
} 

而且

private void RememberOldValues() 
{ 
    ArrayList categoryIDList = new ArrayList(); 
    int index = -1; 
    foreach (GridViewRow row in GridView1.Rows) 
    { 
    index = (int) GridView1.DataKeys[row.RowIndex].Value; 
    bool result = ((CheckBox)row.FindControl("CheckBox1")).Checked; 

    // Check in the Session 
    if (Session[CHECKED_ITEMS] != null) 
    categoryIDList = (ArrayList)Session[CHECKED_ITEMS]; 
    if (result) 
    { 
    if (!categoryIDList.Contains(index)) 
    categoryIDList.Add(index); 
    } 
    else 
    categoryIDList.Remove(index); 
    } 
    if (categoryIDList != null && categoryIDList.Count > 0) 
    Session[CHECKED_ITEMS] = categoryIDList; 
} 

而且

private void RePopulateValues() 
{ 
    ArrayList categoryIDList = (ArrayList)Session[CHECKED_ITEMS]; 
    if (categoryIDList != null && categoryIDList.Count > 0) 
    { 
    foreach (GridViewRow row in GridView1.Rows) 
    { 
    int index = (int)GridView1.DataKeys[row.RowIndex].Value; 
    if (categoryIDList.Contains(index)) 
    { 
    CheckBox myCheckBox = (CheckBox) row.FindControl("CheckBox1"); 
    myCheckBox.Checked = true; 
    } 
    } 
    } 
} 

將數據綁定代碼

/* QUERY */ 
private const string QUERY_SELECT_ALL_CATEGORIES = "SELECT * FROM Categories"; 

private void BindData() 
{ 
    SqlConnection myConnection = new SqlConnection(ConnectionString); 
    SqlDataAdapter ad = new SqlDataAdapter(QUERY_SELECT_ALL_CATEGORIES, 
    myConnection); 
    DataSet ds = new DataSet(); 
    ad.Fill(ds, "Categories"); 
    GridView1.DataSource = ds; 
    GridView1.DataBind(); 
}
