Hi, I'm a newbie in VC# and ADO SQLITE...
I'm trying to change the content of a combobox according to the value present in another one...
My problem is here :
SQLiteCommand cmd3 = new SQLiteCommand("select distinct(ACTION) from ACTION_LIST where CATEGORY='comboBox1.text'", conn2);
What to use to do the job ? Here 'comboBox1.text' is see as a sentence not a variable...
Here is the code :
private void Form1_Load(object sender, EventArgs e)
{
using (SQLiteConnection conn1 = new SQLiteConnection(@"Data Source = Data\MRIS_DB_MASTER"))
{
conn1.Open();
SQLiteCommand cmd2 = new SQLiteCommand("select distinct(CATEGORY) from ACTION_LIST", conn1);
SQLiteDataAdapter adapter1 = new SQLiteDataAdapter(cmd2);
DataTable tbl1 = new DataTable();
adapter1.Fill(tbl1);
comboBox1.DataSource = tbl1;
comboBox1.DisplayMember = "CATEGORY";
adapter1.Dispose();
cmd2.Dispose();
}
using (SQLiteConnection conn2 = new SQLiteConnection(@"Data Source = Data\MRIS_DB_MASTER"))
{
conn2.Open();
SQLiteCommand cmd3 = new SQLiteCommand("select distinct(ACTION) from ACTION_LIST where CATEGORY='comboBox1.text'", conn2);
SQLiteDataAdapter adapter2 = new SQLiteDataAdapter(cmd3);
DataTable tbl2 = new DataTable();
adapter2.Fill(tbl2);
comboBox2.DataSource = tbl2;
comboBox2.DisplayMember = "ACTION";
adapter2.Dispose();
cmd3.Dispose();
}
}
Thanks
regards
