What I have tried:

private void Form1_Load(object sender, EventArgs e)  
       {  
           // TODO: This line of code loads data into the 'bssDataSet.roba_usluge' table. You can move, or remove it, as needed.  
           this.roba_uslugeTableAdapter.Fill(this.bssDataSet.roba_usluge);  
  
  
  
           SqlConnection con = new SqlConnection("Data Source=.\\SQLEXPRESS;Initial Catalog=bss;Integrated Security=True");  
           //SqlCommand cmd = new SqlCommand("SELECT Concat(ime),data FROM roba_usluge", con);  
          // SqlCommand cmd = new SqlCommand("SELECT (redni_broj),data FROM roba_usluge", con);  
           SqlCommand cmd = new SqlCommand("SELECT (ime), data FROM roba_usluge", con);  
          // SqlCommand cmd = new SqlCommand("SELECT Concat(ime, cijena_sa_porezom),data FROM roba_usluge", con);  
  
           // Getting all the data to ItemTable        
           var da = new SqlDataAdapter(cmd);  
           var ItemTable = new DataTable();  
           da.Fill(ItemTable);  
  
           con.Open();  
           Int32 count = ItemTable.Rows.Count;  
           con.Close();  
  
           int top = 50;  
           int left = 50;  
           for (int i = 1; i <= count; i++)  
           // for (int i = 0; i < count; i++)      
           {

You're already creating the button in your code. So when you create the button, just attach an event handler to it. You can use the same eventhandler for all the buttons.

Something like

C#

...
Button button = new Button();  
button.Size = new Size(128,128);  
button.BackColor = Color.Transparent;  
button.Click += new System.EventHandler(dynamicbutton_Click);
...

and then in the same class you would have the event handler

void dynamicbutton_Click(object sender, EventArgs e) {
  // do something
}

If you need, you can add some identification to Tag property to distinguish the buttons fro each other once they are clicked. See Control.Tag Property (System.Windows.Forms)[^]
