Put your filtered customer into a DataTable(dt) and fill like this:
DropDownList2.DataTextField = "CustomerName";
DropDownList2.DataValueField = "CustomerID";
DropDownList2.DataSource = dt;
DropDownList2.DataBind();

The list2 will change its value once the list1 trigger the selectedindexchanged event.

I am having a textbox on my web form. Within this textbox I am using Jquery Auto Complete. I have taken two labels on my web form and trying to hide this label based on the condition I have given in the TextChanged event of the Textbox. But I am not able display the visible one.
This is my aspx page-

}
else

Please guide me where I am doing wrong?

If am not wrong, please try by setting autopostback = true, change your asp tag line like this,
<asp:TextBox ID="TextBox1" runat="server" ontextchanged="TextBox1_TextChanged1" AutoPostBack="True"></asp:TextBox>
Update
Try your coding in this way,
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack == false)
{
bind1();
//Panel1.Visible = true;
}
}
protected void TextBox1_TextChanged1(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ConnectionString);
con.Open();
SqlCommand cmd = new SqlCommand("select name from tbl_data_show where name='"+TextBox1.Text+"'", con);
// DataTable dt1 = new DataTable();
// SqlDataAdapter da = new SqlDataAdapter(cmd);
// da.Fill(dt1);
SqlDataReader dr = cmd.ExecuteReader();
if (dr.HasRows)
{
while (dr.Read())
{
Panel1.Visible = true;
//if (dt1.Rows.Count > 0)
//{
// if (TextBox1.Text == dr.GetString(0))
// {
// //Label1.Text = "4";
// //Label2.Text = "5";
// Panel1.Visible=true;
// //Label1.Visible = true;
// //Label2.Visible = false;
// }
// else
// {
// //Label2.Text = "5";
// Panel1.Visible = false;
// //Label2.Visible = true;
// //Label1.Visible = false;
// }
//}
}
}
else
{
Panel1.Visible = false;
}
con.Close();
}
Let me know, if you get struggle with this again.

There's something wrong with your code, at this line:
mysql = "delete from messages where messageID = '" + CheckBox1.Checked + "'";
It should be:
mysql = "delete from messages where messageID = '" + ((YourClass)Repeater1.Items[i].DataItem).messageID + "'";
And you should use SqlParameter instead of concatenating the String.
Besides, SqlCommand was not executed, you should add this line:
cmdDel.ExecuteNonQuery();
And you must reload data after deleting message.
Besides, you should initialize SqlConnection Object out of the for loop, and use SqlTransaction to manage the transaction.
using (SqlConnection conn = new SqlConnection("Data Source=19-20\\sqlexpress;" + "Initial Catalog = mpsip; Integrated Security = SSPI"))
{
conn.Open();
SqlCommand cmdDel = conn.CreateCommand();
SqlTransaction transaction = conn.BeginTransaction("MyTransaction");
cmdDel.Connection = conn;
cmdDel.Transaction = transaction;
try {
for (int i = 0; i < Repeater1.Items.Count; i++)
{
//This assumes data type of messageID is integer, change (int) to the right type
cmdDel.CommandText = "delete from messages where messageID = '" + ((int)((DataRow)Repeater1.Items[i].DataItem)["messageID"]) + "'";
cmdDel.ExecuteNonQuery();
// Continue your code here
}
transaction.Commit();
//TODO: reload data here and binding to Repeater
}
catch(Exception ex) {
try {
transaction.Rollback();
}
catch(Exception ex1) {
//TODO: write log
}
}
}
