1. Define the Fault ID member variable in your form
2. Call the form constructor using that ID
3. Set the controls in your Form load.
Something like following:
int _nFaultID = -1;
public updateFaults(int i)
{
InitializeComponent();
_nFaultID = i;
}
private void updateFaults_Load(object sender, EventArgs e)
{
cmbclient.Text = _nFaultID .ToString();
cmbcategory.Text =_nFaultID .ToString();
cmbsys.Text = _nFaultID .ToString();
cmbsite.Text =_nFaultID .ToString();
}
