I am using ASP.NET C#, does anyone know what happened?
I had the same problem and found out that I had forgotten to include the script in the file which I want to include in the live site.
Also, you should try this:
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));
Here is the code with line 156, it has try and catch above it
/// <summary>
/// Execute a SQL Query statement, using the default SQL connection for the application
/// </summary>
/// <param name="query">SQL query to execute</param>
/// <returns>DataTable of results</returns>
public static DataTable Query(string query)
{
DataTable results = new DataTable();
string configConnectionString = "ApplicationServices";
System.Configuration.Configuration WebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~/Web.config");
System.Configuration.ConnectionStringSettings connString;
if (WebConfig.ConnectionStrings.ConnectionStrings.Count > 0)
{
connString = WebConfig.ConnectionStrings.ConnectionStrings[configConnectionString];
if (connString != null)
{
try
{
using (SqlConnection conn = new SqlConnection(connString.ToString()))
using (SqlCommand cmd = new SqlCommand(query, conn))
using (SqlDataAdapter dataAdapter = new SqlDataAdapter(cmd))
dataAdapter.Fill(results);
return results;
}
catch (Exception ex)
{
throw new SqlException(string.Format("SqlException occurred during query execution: ", ex));
}
}
else
{
throw new SqlException(string.Format("Connection string for " + configConnectionString + "is null."));
}
}
else
{
throw new SqlException(string.Format("No connection strings found in Web.config file."));
}
}
Check your problem is solved.
