I'm trying to create a DataGridView at runtime whenever I press a button.
I also want to present the data from a table in my database.
When I press the Button that should create a DataGridView and show the data, but it just does nothing. It doesn't create the DataGridView.
Here is my code (the table is called "supplies"):
public partial class managerpage : Form
{
int idWorkersDB = 0;
int idAccountsDB = 1;
int idSuppliersDB = 2;
int idOtherDB = 3;
public static DataGridView workersView = new DataGridView();
public static DataGridView suppliesView = new DataGridView();
public static DataGridView accountsView = new DataGridView();
int clickedID;
private void picBoxSuppliers_MouseUp(object sender, MouseEventArgs e)
{
suppliesView.Location = new Point(59, 51);
suppliesView.Size = new Size(749, 399);
clickedID = idSuppliersDB;
dataDBPanel.Visible = true;
dataDBPanel.Dock = DockStyle.Fill;
titleDataLbl.Text = "Suppliers Data";
titleDataLbl.Left = (this.Width - titleDataLbl.Width) / 2;
OleDbConnection con = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=G:\project\FUCKINGVISUALSTUDIOISSOSHIT\loginData.mdb");
OleDbDataAdapter cmd = new OleDbDataAdapter("SELECT * FROM supplies", con);
con.Open();
DataTable tbl = new DataTable();
cmd.Fill(tbl);
con.Close();
suppliesView.DataSource = tbl;
suppliesView.Show();
}
}

You are hiding most of the code, but I suspect you never add that suppliesView (a datagridview?) to the form. Here is a sample code that works wonderfully well:
void Main()
{
DataTable t = new DataTable();
using (var con = new SqlConnection(@"server=.;Database=Northwind;Trusted_Connection=yes"))
using (var cmd = new SqlCommand(@"select * from Customers", con))
{
con.Open();
t.Load(cmd.ExecuteReader());
con.Close();
}
var f = new Form();
var dgv = new DataGridView { Dock = DockStyle.Fill, DataSource=t};
f.Controls.Add(dgv);
f.Show();
}
