Its frustrating now. Place complete code of page load event of Default2.aspx in (!Page.IspostBack). Use debugger to know the problem and check whether the values are retrieved from db or not .

Check whether the query string[id] is passed to Default2.aspx page. You can also check in the url.

Go to design mode Gridview properties events on top double click on rowcommand event
Following event is fired

protected void gv_RowCommand(object sender, GridViewCommandEventArgs e)
    {
       
    }
Place the code in above.
 LinkButton lnk = (LinkButton)FindControl("LinkButton1");
        if (e.CommandName == "edit")
        {
            Response.Redirect("Default.aspx?id"+ e.CommandArgument);
           //e.CoomandArgument is id.

        }

by do this
error is occurred....
Error :'ASP.default_aspx' does not contain a definition for 'gv_RowCommand' and no extension method 'gv_RowCommand' accepting a first argument of type 'ASP.default_aspx' could be found (are you missing a using directive or an assembly reference?)

Place the event in bold. Now row event is going to be fired
                    AutoGenerateColumns="False" BackColor="White"
                    BorderColor="#3366CC" BorderStyle="None" BorderWidth="1px" CellPadding="4"
                    DataKeyNames="Emp_code" DataSourceID="SqlDataSource1" Height="154px"
                    Width="670px" onrowcommand="gv_RowCommand">

Place a break point at this part of code and check whether this executing?
protected void gv_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        LinkButton lnk = (LinkButton)FindControl("LinkButton1");
        if (e.CommandName == "edit")
        {
            Response.Redirect("Default.aspx?id"+ e.CommandArgument);
           //e.CoomandArgument is id.

        }

Convert to string.
txtempcode.Text=dr["Emp_code"].ToString();
   txtname.Text = dr["Name"].ToString();
   txtaddress.Text = dr["Address"].ToString();
   rblsex.Text = dr["Sex"].ToString();
   txtdob.Text = dr["DOB"].ToString();
   ddldesi.Text=dr["Desiganation"].ToString();

hi madhu..
i have face one problem yr...
when i m coding on default.aspx2, and write that code:
  SqlDataReader dr = Sqlcmd.ExecuteReader();
   while (dr.Read())
   {
   //columns name in the table as in database.
   txtempcode.Text=dr["Emp_code"];
   txtname.Text = dr["Name"];
   txtaddress.Text = dr["Address"];
   rblsex.Text = dr["Sex"];
   txtdob.Text = dr["DOB"];
   ddldesi.Text=dr["Desiganation"];
   }

then this comes.....
Error :Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?

That is what I mentioned in my previous post using template field instead of.

You can use Button instead of link button.

i dont use a link button in gridview.. in gridview i take a command field for select a row....

Madhu K16y ago

Instead of the command field use
 <asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Edit" 
CommandArgument="<%# Eval("id")%>" Text="Select">asp:LinkButton>
ItemTemplate>
asp:TemplateField>

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        LinkButton lnk = (LinkButton)FindControl("LinkButton1");
        if (e.CommandName == "edit")
        {
            Response.Redirect("Default.aspx?id"+ e.CommandArgument);
           //e.CoomandArgument is id.

        }
    }


In default2.aspx pageload
int id =Convert.ToInt32(Request.QueryString["id"]);
use datareader to get the values of the row based on id.

Hope you know how to insert into db.
On Button click event Insert the textbox text, radiobuttonlist and dropdownlist values into db.
get the inserted values from db and bind it to gridview.
Use the button in item template of gridview and redirect to new page with the ID.
using the ID get the values from db and fill the text boxes.
