Compiler Error Message: CS1061

Question

In my local machine, its working perfect but when I upload in my hostname, error occured.

 

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

 

This is my code in desgn page

 

Line 58: <asp:TextBox ID="TextBoxCustomerNo" runat="server" OnTextChanged="TextBoxCustomerNo_TextChanged" AutoPostBack="True" CssClass="form-control" width="400px"></asp:TextBox>

 

this is my code behind:

{
//Search for the Customer from database
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
con.Open();
SqlCommand com = new SqlCommand("Select * from CustomerData Where CISno= '" + TextBoxCustomerNo.Text + "'", con);
//SqlDataAdapter da = new SqlDataAdapter(com);
SqlDataReader dr = com.ExecuteReader();
