I have 3, 1 to Many related tables. Let's say Customers to Orders and then Orders to Item Details. I have
a window that displays all three dgv's. When I select a customer, I want the orders for that customer to all display and the active order to display all items.
When I select a different Customer, the grids all update. I have it working, but it is a bit weird. There must be a more elegant example of how to accomplish this? I am happy to read more. I just can't seem to find a good example of this idea.
The following is an example. When dgvCustomers grid selector changes, it calls a getOrders with the new customer id. Generally this works, but when I added a third link (to items for my example), I get "beeps". It is still working and updating, but I can't find the error.
Then, getOrders updates as follows. And the exact same link to table 3.

Code:
private void dgvCustomers_SelectionChanged(object sender, EventArgs e)
{
try
{
getOrders(dgvCustomer.CurrentRow.Cells["CustomerID"].Value.ToString());
}
catch (Exception ex)
{
//Nothing
}
}Code:
private void getOrders(string sCustID)
{
string sSQLOrders = "SELECT * from Orders Where CustomerFK = " + sCustID;
DataClass ProvCurrentDB = new DataClass(sDBConnection);
ProvCurrentDB.OpenConnection();
//Load the data to the screen.
SqlDataAdapter sda = ProvCurrentDB.ExecuteAdapter(sSQLOrders ); //
DataTable dt = new DataTable();
sda.Fill(dt);
//bsSQLData.DataSource = dsSQLData.Tables["Orders"];
dgvOrders.DataSource = dt;
dgvOrders.Refresh();
int iOrderCount = dgvOrders.Rows.Count - 1; //subtract one to not count the "add" row.
txtBoxOrderCount.Text = iOrderCount .ToString("N0");
Application.DoEvents();
this.Refresh();
}
