Question

As you see, my code (it’s in myform_load), when I run project, it continues to line 1. Just not run other lines after that. I got no error, but the code doesn’t run completely. After it come to line one, myform is shown. Where is the problem?

SqlDataAdapter userSharj_history;
private void myform_Load(object sender, EventArgs e)
{
    using (SqlConnection con = new SqlConnection(connectionString))
    {
         con.Open();
         using (userSharj_history = new SqlDataAdapter(String.Format("SELECT * FROM users_sharj WHERE user_id = {0} AND datetime BETWEEN '{1}%' AND '{2}%'", user_id, az_tarikh_globalizationDateTimePicker1.Text, ta_tarikh_globalizationDateTimePicker1.Text), con))
         {
1.           userSharj_history.Fill(nan_DataSet, "sharjes");
2.           gridControl1.DataSource = nan_DataSet.Tables["sharjes"];
         }
         con.Close();
    }
    view_btn.Focus();
}

• The Query string is fine. I tested it in GUI Query Builder.
• I use this dataset in my main form that call this form and there is no table in it with the name sharjes.

Either check the Output window or enable reporting of all exceptions. Visual Studio will not inform you about many exceptions by default.

Go to menu Debug –> Exceptions… and then tick Thrown for Common language runtime Exceptions and click OK. Run your code again and see if it throws an exception now.
