im getting this error while trying to connect a mysql database to an editor, here is the code behind:
protected void Button1_Click(object sender, EventArgs e)
{
DataTable dt = new DataTable();
MySqlConnection conn = new MySqlConnection(@"connection string");//tested and working
conn.Open();
MySqlCommand cmd = new MySqlCommand("SELECT tes FROM ins");
MySqlDataAdapter da = new MySqlDataAdapter(cmd);
da.SelectCommand = cmd;
da.Fill(dt);
if (dt.Rows.Count > 0)
{
Editor1.Content = dt.Rows[0]["tes"].ToString();
}
conn.Close();
}
and here is the aspx page code:
<body>
<form id="form1" runat="server">
<cc1:Editor ID="Editor1" runat="server" Height="400px" Visible="true" />
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
</form>
what am i doing wrong, thanks in advance.

Change the line
MySqlCommand cmd = new MySqlCommand("SELECT tes FROM ins");
To
MySqlCommand cmd = new MySqlCommand("SELECT tes FROM ins", conn);
And it should work.
Alternatively assign conn to the cmd.Connection property.
The problem with your code is that you never assign a connection to the command, hence the error saying that the connection is not initialized.

Try This
MySqlCommand cmd = new MySqlCommand("SELECT tes FROM ins",conn);
or
MySqlCommand cmd = new MySqlCommand("SELECT tes FROM ins");
cmd.Connection=conn;
