How to solve the compiler error CS1061 'GridView1_RowCommand'

Question

My PROBLEM: my local machine, it's working perfectly but when I uploaded it to my domain, an error occurred.

 

Compilation Error

 

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

 

Compiler Error Message: CS1061: 'ASP.customerregister_aspx' does not contain a definition for 'GridView1_RowCommand' and no extension method 'GridView1_RowCommand' accepting a first argument of type 'ASP.customerregister_aspx' could be found (are you missing a using directive or an assembly reference?)

Source Error:

Line 322: <td > Line 323: <asp:Label ID="Nodata" runat ="server" Visible="false" Text="please add the data" ForeColor ="Red" Font-Bold ="true" Font-Size ="X-Large"></asp:Label> Line 324: <asp:GridView ID="GridView1" Class="myGridClass" runat="server" AutoGenerateColumns="false" HorizontalAlign="Right" PageSize="10" AllowPaging="true" OnPageIndexChanging="OnPaging" OnRowCommand="GridView1_RowCommand" OnRowDeleting="GridView1_RowDeleting" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" DataKeyNames="ID"> Line 325: <RowStyle CssClass="gridCSS" /> Line 326: <AlternatingRowStyle CssClass="gridAlternateCSS" />

 

What I have tried

 

Frontend code:

<asp:GridView ID="GridView1" Class="myGridClass" runat="server" AutoGenerateColumns="false" HorizontalAlign="Right" PageSize="10" AllowPaging="true" OnPageIndexChanging="OnPaging" OnRowCommand="GridView1_RowCommand" OnRowDeleting="GridView1_RowDeleting" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" DataKeyNames="ID">

<ItemTemplate>
 <asp:LinkButton ID="lnkview" runat="server" CssClass="gridCSS" ForeColor="green" Font-Bold="true" CommandArgument='<%# Eval("ID") %>' OnClick="lnk_OnClick">Edit</asp:LinkButton>
 <%-- <asp:ImageButton ID="ImageButton1" ImageUrl="~/images/edit-icon.png" runat="server" Width="15" Height="15" CommandArgument='<%# Eval("ID") %>' OnClick="lnk_OnClick" CausesValidation="false"/>--%>

 </ItemTemplate>
 </asp:TemplateField>
 </Columns>
 </asp:GridView>

Backend code:

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e) {
  int ID = Convert.ToInt32(e.CommandArgument.ToString());
  if (e.CommandName == "Delete") {
    if (sqlCon.State == ConnectionState.Open) {
      sqlCon.Close();
    }
    sqlCon.Open();
    SqlCommand sqlCmd = new SqlCommand();
    sqlCmd.Connection = sqlCon;
    sqlCmd.CommandText = "Delete from CustomerRegistration where ID=" + ID + "";
    sqlCmd.ExecuteNonQuery();
    sqlCmd.Dispose();
    sqlCon.Close();
    GridView1.DataBind();
  }
}
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e) { //
int index = Convert.ToInt32(e.RowIndex); //
DataTable dt = ViewState["dt"] as DataTable; //
dt.Rows[index].Delete(); //
ViewState["dt"] = dt; //
GridView1.DataSource = dtbl; GridView1.DataBind(); }
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e) { }
