Hello everyone,
I m working on c# windows application. I have two combobox for
1. Bank
2. Branch
My question is when i select a bank from bank_name combobox relevent
branches show in branc_name combobox.
I m using
private void Dispatch_Load(object sender, EventArgs e)
{
ds = d1.select_bank();
bank_name.DataSource = ds.Tables["bank"];
bank_name.DisplayMember = "bank_name";
bank_name.SelectedIndex = -1;
bank_name.Text = "----Select Bank--------";
branch_name.DataSource = null;
branch_name.Items.Clear();
frm_no.Enabled = false;
dispatchdate = dispatchDate.Text.ToString();
}
private void bank_name_SelectedIndexChanged(object sender, EventArgs e)
{
branch_name.DataSource = null;
branch_name.Items.Clear();
try
{
ds1 = d1.select_branch1(bank_name.Text);
branch_name.DataSource = ds1.Tables["branch"];
branch_name.DisplayMember = "branch_name";
branch_name.SelectedIndex = -1;
branch_name.Text = "------ Select Branch-----";
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
My problem is when i select any item from bank_name combobox in branch_name
combobox previous values are not cleared.
Thanx
