ladies and gentlemen, once again I unfortunately am going to bother you with newbie stuff. I have searched for this information for hours, so if there’s a thread with what I want on it, it’s buried deeper than I could find.
This was my first question here, and Mark Hall was kind enough to set me straight. Since then, I have created a new project and recreated my first three screens as user controls – a container/login, a choice screen, and a main screen (currently empty). If a user has more than one collection, the choice screen pops up and allows them to choose a collection.
I did run into a snag with parameters, but I’m solving that by overloading the form declaration (solution found here) – yes, I know it’s much better to send parameters through calls, but I’d hate to have to create a call for each parameter (do I?) and… OK, OK, I’m better at this than {get, set}. Man, I hate being a newbie.
Anyways, I’m having trouble with the choice form – I can’t seem to call it, close it, then go to the main form. I have no problem (if there’s only one collection) in going straight to the main form, it’s that darn choice form. Yes, I know I could include a choice datagridview, but a few of our end users aren’t the sharpest bulb in the tool shed, and need hand-holding. Anyways, here’s the code.
CONTAINER/LOGIN SCREEN
namespace DeleteThis
{
public partial class ContainerForm : Form
{
Main Main = new Main();
LoginCollectionChoice LoginChoice = new LoginCollectionChoice();
DataTable dtPermissions = new DataTable();
public ContainerForm()
{
InitializeComponent();
Main.ExitEvent += new Main.ExitEventHandler(Main_ExitEvent);
LoginChoice.ExitEvent += new
LoginCollectionChoice.ExitEventHandler(LoginChoice_ExitEvent);
}
void LoginChoice_ExitEvent(object sender, EventArgs e)
{
pnlcontainer.Controls.Remove(LoginChoice);
}
void Main_ExitEvent(object sender, EventArgs e)
{
pnlcontainer.Controls.Remove(Main);
}
private void btnLogin_Click(object sender, EventArgs e)
{
LoginProcedure();
}
private void LoginProcedure()
{
DataTable dtPermissions = AdminClass.GetCollectionsForUser(int.Parse(txtbxUserName.Text));
if (dtPermissions.Rows.Count == 1)
{
//Valid user, one collection. Head right in.
pnlcontainer.Controls.Add(Main);
Main.BringToFront();
}
else
{
//More than one collection found. Giving user choice
LoginCollectionChoice LoginChoice = new LoginCollectionChoice(dtPermissions);
pnlcontainer.Controls.Add(LoginChoice);
LoginChoice.BringToFront();
}
}
private void btnExitProgram_Click(object sender, EventArgs e)
{
this.Close();
}
}
}
I hope I didn't kill anything in the snipping. And now the choice screen…
public partial class LoginCollectionChoice : UserControl
{
public delegate void ExitEventHandler(object sender, EventArgs e);
public event ExitEventHandler ExitEvent;
private static DataTable dtPermit;
DataTable dtPermissions = new DataTable();
public LoginCollectionChoice()
{
}
public LoginCollectionChoice(DataTable dtPermissions)
{
InitializeComponent();
GrdCollection.DataSource = dtPermissions;
dtPermit = dtPermissions;
}
private void btnChoose_Click(object sender, EventArgs e)
{
//Code for the user to choose a collection
ExitEvent(this, new EventArgs());
}
}
I’ve snipped all non-relevent code, I hope you gentlemen and ladies can help this newbie get on the right path. Please, be gentle, you wouldn’t want to see me cry, would you? :) Oh! And if you know of any great tutorial sites, please email them to me. I'd prefer to spend a week on tutorials than a week on stumbling and asking here. Thank you all very much.
