aspx.cs

aspx.cs

  protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Control FeaturedProductUserControl = new Control();
        FeaturedProductUserControl = LoadControl("WebUserControl1.ascx");
        FeaturedProductUserControl.EnableViewState = true;
        Div_UserControlPlace.Controls.Add(FeaturedProductUserControl);
    }

    protected void Button2_Click(object sender, EventArgs e)
    {
        Control FeaturedProductUserControl2 = new Control();
        FeaturedProductUserControl2 = LoadControl("WebUserControl2.ascx");
        FeaturedProductUserControl2.EnableViewState = true;
        Div_UserControlPlace2.Controls.Add(FeaturedProductUserControl2);
        
    }

我加载第一个用户控件，点击第一个按钮，一切正常，但是当

i load a first user control with click on first button all thing work properly but when

我点击其他按钮加载第二个UserControl 第一个UserControl dis出现（删除）和第二个用户控制加载

i click on other button for load second UserControl  first UserControl dis Appear(Remove) And Second User Control Load
