How to solve the compiler error CS1061 'GridView1_RowCommand'

May 3 2021 12:08 PM
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" />

Backend code:
  1. protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e) {  
  2.   int ID = Convert.ToInt32(e.CommandArgument.ToString());  
  3.   if (e.CommandName == "Delete") {  
  4.     if (sqlCon.State == ConnectionState.Open) {  
  5.       sqlCon.Close();  
  6.     }  
  7.     sqlCon.Open();  
  8.     SqlCommand sqlCmd = new SqlCommand();  
  9.     sqlCmd.Connection = sqlCon;  
  10.     sqlCmd.CommandText = "Delete from CustomerRegistration where ID=" + ID + "";  
  11.     sqlCmd.ExecuteNonQuery();  
  12.     sqlCmd.Dispose();  
  13.     sqlCon.Close();  
  14.     GridView1.DataBind();  
  15.   }  
  16. }
