推荐答案

在TextBox事件中添加此代码...




受保护的void TextBox1_TextChanged(对象发送者，EventArgs e)
{
SqlConnection con =新的SqlConnection(@数据源= MAJ-056 \ SQLEXPRESS;初始目录=示例；集成安全性= True");
con.Open();
SqlCommand cmd =新的SqlCommand(从TABLENAME中选择*，其中TicketID =" + Convert.ToInt64(TextBox1.Text)+"，con);
SqlDataReader dr = cmd.ExecuteReader();
如果(！dr.Read())
{
Response.Write("Invalid Ticket ID");
}
con.Close();
}

Add this code in TextBox event...




protected void TextBox1_TextChanged(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection(@"Data Source=MAJ-056\SQLEXPRESS;Initial Catalog=Sample;Integrated Security=True");
con.Open();
SqlCommand cmd = new SqlCommand("select * from TABLENAME where TicketID=" + Convert.ToInt64(TextBox1.Text) + "", con);
SqlDataReader dr = cmd.ExecuteReader();
if (!dr.Read())
{
Response.Write("Invalid Ticket Id");
}
con.Close();
}
