<form id="form1" runat="server">
<div>
<asp:DataList ID="Mydatalist" runat ="Server"
              OnItemCommand="Mydatalist_ItemCommand" >
  <ItemTemplate >
    <table >
      <tr>
        <td>
          <asp:Label ID="lblcouname" runat ="server"
                     Text ='<%# Eval("country_name") %>'></asp:Label>
        </td>
        <td> 
          <asp:LinkButton ID="lnkrepl" Text="reply"
                          CommandName ="reply" runat ="server"
                          CommandArgument ='<%# Eval("country_id") %>'>
          </asp:LinkButton>

    </table>
    <div>
       <asp:Panel ID="mypane" runat ="Server" Visible ="false"  >
         <asp:TextBox ID="txtpane" runat ="Server" ></asp:TextBox><br />

       </asp:Panel>
    </div>
  </ItemTemplate>
</asp:DataList>
</div>
</form>

Code behind:

public partial class Datlist : System.Web.UI.Page
{
SqlConnection con; SqlDataAdapter da; DataSet ds;
protected void Page_Load(object sender, EventArgs e)
{
    con = new SqlConnection(
         @"server=msmsm;database=pop;user id=sa;password=abc");
    con.Open();
    if (!IsPostBack)
   开发者_开发知识库 {
        getCountry();
    }
}
public void getCountry()
{
    string sqr="select * from country";
    da=new SqlDataAdapter (sqr,con);
    ds = new DataSet();
    da.Fill(ds,"country");
    Mydatalist.DataSource = ds.Tables[0];
    Mydatalist.DataBind();
}
protected void Mydatalist_ItemCommand(object source, DataListCommandEventArgs e)
{
    Panel pn = (Panel)e.Item.FindControl("mypane");
    pn.Visible = false;
    if (e.CommandName == "reply")
    {

        pn.Visible = true;
    }
}
}

You have to programmably hide it. THe DataList should have an items property, and as such you can loop through all items, find the panel control using FIndControl, and set its visibility to false.

EDIT: So you need to do:

private void HideItems()
{
    foreach (var item in this.dl.Items)
    {
       var panel = item.FindControl("mypane") as Panel;
       if (panel != null)
           panel.Visible = false;
     }
}

In ItemCommand, call this method to hide all the existing control's panels.
