Asalamu alikum家伙，我在同一页面上使用2个控件，两个控件都有自己的源代码中使用的更新面板，但问题是我在两个控件上都使用了pagging，当我到达一个页面的结束页面时控制，如果我尝试更改其他控件的页面索引，则第一个控件显示空白而没有记录。我在我的页面上使用特价控制和包控制。两个控件都使用数据集来显示记录
热门交易控件的热门代码：
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

打包包控件的代码：
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();
}

The sport of white water river rafting calls for a triumph over the swift swirling

答案 0 :(得分：1)
尝试使用UpdateMode="Conditional"和ChildrenAsTriggers="true"作为更新面板，
并添加Triggers ，这会阻止一个更新面板影响其他面板
<asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">
