Web Forms :: How To Use Server UrlEncode With LinkButton Inside GridView ItemTemplate

I have two page

1-index.aspx

protected void ImageButton3_Click(object sender, ImageClickEventArgs e) {
string data = Server.UrlEncode(txtNumeric.Text);
SqlCommand _cmd = new SqlCommand("traidname", _cn);
_cmd.CommandType = CommandType.StoredProcedure;
_cmd.Parameters.Add("@BehCode", data);

[Code] ....

Here I use textbox .text for server.urlEncode according to this code it go to tName + "?BehCode=" that 

SP

ALTER procedure [dbo].[traidname]
@Behcode nvarchar(30)
as
begin
select T_name
from House_Info
where Behcode=@Behcode
end

And this is code in my destination(depending to tname column in house_info tabel) page

I use below code to bind data from database in destination pages

  string data = Server.UrlDecode(Request.QueryString["BehCode"]); _cmd.Parameters.AddWithValue("@behcode", data);

Now in index.aspx page i have linkbutton that i want when users click on it, it do something like

ImageButton3_Click  event 

This is my datalist code that linkbutton is in this datalist

  <asp:DataList ID="DDLstore" runat="server" RepeatColumns="3" RepeatDirection="Horizontal" "> <ItemTemplate> <table class="DDL2h"> <tr> <td style="height: 35px"> <asp:Label ID="Label3" runat="server" Text='<%# Eval("Name") %>' CssClass="TDnameH"></asp:Label> </td> <tr> <td> <asp:LinkButton ID="LinkButton2" runat="server" CssClass="LBP2" onclick="LinkButton2_Click">see all product</asp:LinkButton> </td> </tr> </table> </ItemTemplate> </asp:DataList>

Now how I can write code for linkbutton event that do same thing like ImageButton3_Click event?

and notice that both linkbutton and imagebutton are in index.aspx page ...
