C# help I do not know where I put the code

Hello, I have 2 textboxes (tbMarcas and tbSubmarcas) Brands and Sub-brands both with autocomplete, but sub-brands need to work first met brands and I do not know how to make it work correctly, there is how I did the code ..

/ / Both operating
private void Auto_marcas (); [...]
private void Auto_submarcas (); [...]

private void Form1_Load (object sender, EventArgs e)
{
CONNECTION.Open ();
Auto_marcas () / / when compiling works 5 stars loads 6000 records in 1sec and makes the autocomplete function
Auto_submarcas () / / this also works but only if compiled tbMarcas with text on it in the textbox, I know it is to be in the load () but do not know where to put it to work, this is my question!
}

/ / I've tried this way but does not result

...
private void Auto_marcas (); [...]
private void Auto_submarcas (); [...]

private void Form1_Load (object sender, EventArgs e)
{
CONNECTION.Open ();
Auto_marcas ();

}
private void tbMarcas_Leave (object sender, EventArgs e)
{
Auto_submarcas ();
}
...

How do I solve this problem?

If I understand your question correctly, do you want to load the sub-brands based on the brand entered into the textbox?

If it is yes, then try to place the Auto_submarcas() event in the tbMarcas_TextChanged event or tbSubmarcas_Enter() event.

private void tbMarcas_TextChanged(object sender, EventArgs e)
{
Auto_submarcas();
}

private void tbSubmarcas_TextChanged(object sender, EventArgs e)
{
Auto_submarcas();
}

Please let me know, if you're expecting something different.
