C Sharp :: Using Textbox To Filter From DataGridView And SQLite Database
Mar 11, 2013I'm trying to get some more user friendly things in my program done. Now I'm trying to filter by typing in a text box and it filters to what you are typing and shows the entire row.
This is what I currently have:
private void txtFilter_TextChanged(object sender, EventArgs e) {
try {
SQLiteConnection connect = new SQLiteConnection(connString);
connect.Open();
[Code] ....
I get an exception error though:
SQLite error
near "'N'": syntax error
// N is what I started typing to start the filter.
Ok, so I've edited the code now to this:
private void txtFilter_TextChanged(object sender, EventArgs e) // FILTER TODO {
DataView view = new DataView();
SQLiteConnection connect = new SQLiteConnection(connString);
connect.Open();
view.RowFilter = "Channel like '%" + txtFilter.Text + "%'";
}
No more exception errors, just not what I want it to do. It just keeps everything there.
