Hello all,

I am developing a project in which I am having a treeview and it is populated from the database, I want to insert the checked item in treeview to database after clicking a button, I am not getting how to insert the checked item in tree view to database.My code in button click event looks like this. Can any one help me...

C#
protected void btn1_Click(object sender, EventArgs e) 
{ 
     SqlConnection con = new SqlConnection("Data Source=GAYATHRI\SQLEXPRESS;Initial      Catalog=VOY_SERVICES1;Integrated Security=True"); con.Open();
 
    foreach (TreeNode tnode in TreeView1.CheckedNodes)
    {
 

        if (tnode.Checked == true)
        {
 
            string strTreeValue;
            strTreeValue = tnode.Value;
            SqlCommand com = new SqlCommand("insert into treeview_select(subdisease_name) values(@name)", con);
 
            com.Parameters.AddWithValue("@name", strTreeValue);
            com.ExecuteNonQuery();
            con.Close();

Urgency deleted: It may be urgent to you, but it isn't to us. All that your stressing the urgency does is to make us think you have left it too late, and want us to do it for you. This annoys some people, and can slow a response.

OK, but what's wrong, where is the problem?

my problem is that selected node is not getting inserted into the database.

On the first look, youre code seems to be OK, but...
C#
protected void btn1_Click(object sender, EventArgs e) 
{ 
     SqlConnection con = new SqlConnection("Data Source=GAYATHRI\SQLEXPRESS;Initial      Catalog=VOY_SERVICES1;Integrated Security=True"); con.Open();
 
    foreach (TreeNode tnode in TreeView1.CheckedNodes)
    {
        if (tnode.Checked == true)
        {
 
            string strTreeValue;
            strTreeValue = tnode.Value;
            SqlCommand com = new SqlCommand("insert into treeview_select(subdisease_name) values(@name)", con);
 
            com.Parameters.AddWithValue("@name", strTreeValue);
            com.ExecuteNonQuery();
            com.Dispose();
            //con.Close(); if connection is closed, the command will be executed only once!
        }
    }
con.Close();
com = Nothing;
con = Nothing;
}


Have a nice day ;)
