How can I add the name of each button click to a string builder using C#

Question

I'm writing a code for ticket booking. If suppose there are 30 seats and I have added the Button_click for each of the seats. I'm able to get the name of each seat. But I'm not sure how to add the button name of each button to the string builder and so that I can add it to the table one after the other when I press save(Button31_Click) button.

Answer 1

Do not create 30 buttons, just create them dynamically:

 string Seatname = "";
        String output = "";
        string sql = @"select* from[dbo].[BookedTickets]";
        string connectionstring = @"Data 
        Source(local);InitialCatalog=master;Integrated 
        Security=SSPI";
        SqlConnection cnn = new 
        SqlConnection(connectionstring);
        cnn.Open();
        SqlCommand command = new SqlCommand(sql, cnn);
        SqlDataReader dataReader = command.ExecuteReader();
        while (dataReader.Read())
        {
             Button btn = new Button();
             btn.Text = SeatNameorWhatEver // set any properties
             btn.Click += (s,e) => {
                 Button bt = (Button)s;
                 string Seatname = bt.Text;
               };
        }

Of course, you have to set each buttons location. Add it to Form or Panel or whatever

Answer 2

1. Declare string builder var as class level
2. On button click append button text to string builder
3. finally use string builder var as a result of all button click's

Answer 3

Declare one string Globally in your class

string btnsText=string.Empty;

& call this method inside your all button click events to add clciekd button text

public string AppendSeats(string clickedText)
{           
    if(!btnsText.Contain(clickedText))
    {
        //Here adding space, you can add comma, dot etc..
        btnsText = btnsText + " " + clickedText;
    }           
}

Like below you should call it

public void Button1_Click(object sender, EventArgs e)
{
        Button butt1 = (Button)sender;
        AppendSeats(butt1.Text);
}   

Use here your btnsText string

public void Button31_Click(object sender, EventArgs e)
{
   string sql = @"Insert into [dbo].[BookedTickets] 
   ([SeatNo],[Status])values('"+ btnsText+"','true')";

}
