TexBox_TextChange不自动输入数字时触发 [英] TexBox_TextChange not Firing when a number is auto entered

问题描述

我有一个TextBox_TextChange，当从另一个TextChange自动输入一个数字时，它应该触发。我做错了什么？

I have a TextBox_TextChange in place that should fire when a number is auto entered from another TextChange. What did I do wrong?

<td class="style27">
                <asp:TextBox ID="TextBoxNCCDR" runat="server" Width="180px" AutoPostBack="True"  

                ontextchanged="TextBoxNCCDR_TextChanged" Enabled="True" ReadOnly="True"></asp:TextBox>
            </td>

protected void TextBoxNCCDR_TextChanged(object sender, EventArgs e)
   {
       int a = Convert.ToInt32(TextBoxT1234.Text);
       int b = Convert.ToInt32(TextBoxNCCDR.Text);
       TextBoxTCNC.Text = Convert.ToString(a + b);
       TextBoxTNFUG.Focus();
   }

这是计算后自动编号的来源。

Here is where the auto number comes from after calculations.

protected void TextBoxNCC_TextChanged(object sender, EventArgs e)
    {
        SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["PasswordConnectionString"].ConnectionString);
        con.Open();

        if (true)
        {
            SqlCommand level = new SqlCommand("Select INST_ID, Calendar from TableCOCINST where INST_ID = @INST_ID", con); 
            level.Parameters.Add(new SqlParameter("INST_ID", TextBoxINST_ID.Text));
            

            SqlDataReader reader = level.ExecuteReader();
            DataTable dt1 = new DataTable();
            dt1.Load(reader);

            foreach (DataRow dr1 in dt1.Rows)
            {
               string returnedLevel = (dr1[1].ToString());
                int inst_id = Convert.ToInt32(dr1[0].ToString());
                Session["inst_id"] = inst_id;

                if (returnedLevel == "Semester")
               {
                   int i = Convert.ToInt32(TextBoxNCC.Text);
                   int j = 168;
                   TextBoxNCCDR.Text = Convert.ToString(i / j);
 
               }
               else if (returnedLevel == "Quarter")
               {
                   int i = Convert.ToInt32(TextBoxNCC.Text);
                   int j = 120;
                   TextBoxNCCDR.Text = Convert.ToString(i / j);
               }
                }
            }
        }
    }

        SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["PasswordConnectionString"].ConnectionString);
        con.Open();

        if (true)
        {
            SqlCommand level = new SqlCommand("Select INST_ID, Calendar from TableCOCINST where INST_ID = @INST_ID", con); 
            level.Parameters.Add(new SqlParameter("INST_ID", TextBoxINST_ID.Text));
            

            SqlDataReader reader = level.ExecuteReader();
            DataTable dt1 = new DataTable();
            dt1.Load(reader);

            foreach (DataRow dr1 in dt1.Rows)
            {
               string returnedLevel = (dr1[1].ToString());
                int inst_id = Convert.ToInt32(dr1[0].ToString());
                Session["inst_id"] = inst_id;

                if (returnedLevel == "Semester")
               {
                   int i = Convert.ToInt32(TextBoxNCC.Text);
                   int j = 168;
                   TextBoxNCCDR.Text = Convert.ToString(i / j);

                   int a = Convert.ToInt32(TextBoxT1234.Text);
                   int b = Convert.ToInt32(TextBoxNCCDR.Text);
                   TextBoxTCNC.Text = Convert.ToString(a + b);
                   TextBoxTNFUG.Focus();
 
               }
               else if (returnedLevel == "Quarter")
               {
                   int i = Convert.ToInt32(TextBoxNCC.Text);
                   int j = 120;
                   TextBoxNCCDR.Text = Convert.ToString(i / j);

                   int a = Convert.ToInt32(TextBoxT1234.Text);
                   int b = Convert.ToInt32(TextBoxNCCDR.Text);
                   TextBoxTCNC.Text = Convert.ToString(a + b);
                   TextBoxTNFUG.Focus();
               }
                }
            }
        }
    }
