更新面板問題

Asalamu alikum傢伙，我在同一頁面上使用2個控件，兩個控件都有更新面板用於他們自己的源代碼，但問題是我已經在兩個控件上使用了分頁，並且當我到達末尾一個控件的頁面，如果我嘗試更改其他控件的頁面索引，則第一個控件顯示空白且沒有記錄。我在我的頁面上使用熱交易控制和包控制。這兩個控件使用的數據集顯示記錄更新面板問題

代碼pagging上熱賣的控制：

URLMessage URLMessage = new URLMessage(); 
    PagedDataSource dsource = new PagedDataSource(); 
    DataSet _ds = new DataSet(); 
    public static int pos; 
    protected void Page_Load(object sender, EventArgs e) 
    { 
     if (!Page.IsPostBack) 
     { 
      this.ViewState["vs1"] = 0;  

     } 
     pos=(int)this.ViewState["vs1"]; 

     fill(); 
    } 
    private void fill() 
    { 
     RegistrationBAL rbl = new RegistrationBAL(0); 
     rbl.LoadHotDeals(_ds); 
     //******************Adding Regular Price to Dataset 
     ////_ds.Tables[rbl.SqlEntityX].Columns.Add("RegPrice"); 
     ////foreach (DataRow item in _ds.Tables[rbl.SqlEntityX].Rows) 
     ////{ 
     //// item["RegPrice"] = (Convert.ToDouble(item["BaseRate"]) + 0.2 * Convert.ToDouble(item["BaseRate"])); 

     ////} 

     dsource.DataSource = _ds.Tables[rbl.SqlEntityX].DefaultView; 
     dsource.PageSize = 2; 
     dsource.AllowPaging = true; 
     dsource.CurrentPageIndex = pos; 
     btnfirst.Enabled = !dsource.IsFirstPage; 
     btnprevious.Enabled = !dsource.IsFirstPage; 
     btnlast.Enabled = !dsource.IsLastPage; 
     btnnext.Enabled = !dsource.IsLastPage; 
     dlHotDeals.DataSource = dsource; 
     dlHotDeals.DataBind(); 
    } 
    protected void btnfirst_Click(object sender, EventArgs e) 
    { 
     pos = 0; 
     fill(); 
    } 

    protected void btnprevious_Click(object sender, EventArgs e) 
    { 
     pos = (int)this.ViewState["vs1"]; 
     pos -= 1; 
     this.ViewState["vs1"] = pos; 
     fill(); 
    } 

    protected void btnnext_Click(object sender, EventArgs e) 
    { 
     pos = (int)this.ViewState["vs1"]; 
     pos += 1; 
     this.ViewState["vs1"] = pos; 
     fill(); 
    } 

    protected void btnlast_Click(object sender, EventArgs e) 
    { 
     pos = dsource.PageCount - 1; 
     fill(); 
    } 


    protected void dlHotDeals_ItemDataBound(object sender, DataListItemEventArgs e) 
    { 

     int rtid,rgid; 
     // double BaseRate; 
     // BaseRate = WebHelper.Cast(((Label)e.Item.FindControl("lblPrice")).Text, 0); 
     // Label lbl = (Label)e.Item.FindControl("lblRegPrice"); 
    // lbl.Text = (BaseRate + (0.2 * BaseRate)).ToString(); 
     HtmlAnchor lnkBookNow = (HtmlAnchor)e.Item.FindControl("lnkBook"); 

     rtid = WebHelper.Cast(((Label)e.Item.FindControl("lblRTID")).Text, 0); 
     rgid=WebHelper.Cast(((Label)e.Item.FindControl("lblRegID")).Text, 0); 
     lnkBookNow.HRef ="~/RoomTypeDetails.aspx?"+URLMessage.Encrypt("RTID=" +rtid.ToString() + "&RegID=" + rgid.ToString()); 

    } 
}

代碼pagging在包裝上控制：

PagedDataSource adsource = new PagedDataSource(); 
    DataSet _ds = new DataSet(); 
    public static int p; 
    protected void Page_Load(object sender, EventArgs e) 
    { 

     if (!Page.IsPostBack) 
     { 
      this.ViewState["vs"] = 0;  

     } 
     p=(int)this.ViewState["vs"]; 
     fill(); 
    } 
    private void fill() 
    { 
     PackageBAL pbl = new PackageBAL(0); 
     pbl.LoadPackagesAll(_ds); 

     adsource.DataSource = _ds.Tables[pbl.SqlEntityX].DefaultView; 
     adsource.PageSize = 2; 
     adsource.AllowPaging = true; 
     adsource.CurrentPageIndex = p; 
     btnfirst.Enabled = !adsource.IsFirstPage; 
     btnprevious.Enabled = !adsource.IsFirstPage; 
     btnlast.Enabled = !adsource.IsLastPage; 
     btnnext.Enabled = !adsource.IsLastPage; 
     dlPackage.DataSource = adsource; 
     dlPackage.DataBind(); 
    } 
    protected void btnfirst_Click(object sender, EventArgs e) 
    { 
     p = 0; 
     fill(); 
    } 

    protected void btnprevious_Click(object sender, EventArgs e) 
    { 
     p = (int)this.ViewState["vs"]; 
     p -= 1; 
     this.ViewState["vs"] = p; 
     fill(); 
    } 

    protected void btnnext_Click(object sender, EventArgs e) 
    { 
     p = (int)this.ViewState["vs"]; 
     p += 1; 
     this.ViewState["vs"] = p; 
     fill(); 
    } 

    protected void btnlast_Click(object sender, EventArgs e) 
    { 
     p = adsource.PageCount - 1; 
     fill(); 
    }

我想你在這裏粘貼你所有的代碼...... – Usman

請儘量減少你發佈的代碼量，以提供解釋和重現問題所需的最低代碼。 –

嘗試使用UpdateMode="Conditional"和ChildrenAsTriggers="true"爲您更新面板，並添加Triggers這將防止一個更新面板影響其他面板

<asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional"> 
    <Triggers> 
    <asp:AsyncPostBackTrigger ControlID="btnOk" EventName="Click" /> 
    </Triggers> 
    <ContentTemplate> 

    //Your contents here 

    </ContentTemplate> 
</asp:UpdatePanel>

Valekum Salaam。
