如何通过在文本框中输入值来过滤下拉列表中的值

Question

我正在尝试将文本框绑定到C＃中的下拉列表。我无法绑定文本框和下拉列表。

帮我解释一下这段代码

public void BindDropDownListData()
{
    String strConnString = ConfigurationManager.ConnectionStrings["sample11"].ConnectionString;
    using (SqlConnection mySqlConnection = new SqlConnection(strConnString))
    {
        try
        {
            mySqlConnection.Open();
            SqlCommand mySqlCommand = new SqlCommand("dbo.SCM_JOB_DISPLAY", mySqlConnection);
            mySqlCommand.CommandType = CommandType.StoredProcedure;
            SqlDataAdapter mySqlDataAdapter = new SqlDataAdapter(mySqlCommand);
            DataSet myDataSet = new DataSet();
            mySqlDataAdapter.Fill(myDataSet);
            DropDownList1.DataSource = myDataSet;
            DropDownList1.DataTextField = "HTTIS_Issue_Number";
            DropDownList1.DataValueField = "HTTIS_Job_Code";
            DropDownList1.DataBind();
        }
        catch (Exception ex)
        {
            Label1.Text = ex.Message;
        }
        finally
        {
            mySqlConnection.Close();
        }
    }
}

尝试绑定

myDataSet.Tables[0]

而不是整个数据集。
