I have a question .
Please see the screen shots and the code and you will be able to know what is my problem and what I want to do.
Please see both the screen shots.
Thanking you,
This is the code of the form where the Plus sign is there and also the MemberId textbox is also there.That is Form1.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;
using System.Text.RegularExpressions;

namespace CDShop
{
    public partial class Form_BorrowSection : Form
    {
        public Form_BorrowSection()
        {
            InitializeComponent();
        }
        Int32 memberid { get; set; }
        public void getMemberid()
        {
            Int32 id;
            id = Convert.ToInt32(textBox_MemberID.Text);
            memberid = id;
        }


Here is the code of the Form2 .

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;

namespace CDShop
{
    public partial class Form_Borrowed_Items : Form
    {
        public Form_Borrowed_Items()
        {
            InitializeComponent();
        }

        private void Form_Borrowed_Items_Load(object sender, EventArgs e)
        {
            label1.Text = fb.memberid;//fb is the Form1 object


            string b = "Borrowed";
            string query = "select * from Table_Borrow where MemberID=@parameter1 and Status LIKE '" + b.ToString() + "' ";
            using (SqlConnection con = new SqlConnection("Data Source=INVENTOR-1D70F6\\SQLEXPRESS;Initial Catalog=AnindyaCD;Integrated Security=SSPI"))
            {
                using (SqlCommand cmd = new SqlCommand(query, con))
                {
                    cmd.Parameters.AddWithValue("@parameter1", MemberID);

                    using (SqlDataAdapter ad = new SqlDataAdapter(query, con))
                    {
                        ad.SelectCommand = cmd;
                        DataSet ds = new DataSet();
                        ad.Fill(ds, "Table_Borrow");
                        dataGridView5.DataSource = ds.Tables[0];
                    }
                }
            }
        }
    }
}

When clicking the plus, get the member id textbox value and pass to the second form through the constructor or through a property...

class Form1
{

on_plus_clicked_handler(...)
{

string memberId = textBoxMemberId.Text

Form2 form2 = new Form2(memberId);
//show form2

OR

Form2 forms = new Form2();
form2.MemberID = memberID;

}

}





class Form2
{

private string _memberId = string.Empty;


public string MemberID
{
get {return _memberId;}
set { _memberId = value; }
}

public Form2(string memId)
{

_memberId  = memId; // use _memberId later

}



}

Filling that in your code, it would look like:


public partial class Form_BorrowSection : Form
    {
        public Form_BorrowSection()
        {
            InitializeComponent();
        }

        Int32 memberid { get; set; }
        public void getMemberid()
        {
            Int32 id;
            id = Convert.ToInt32(textBox_MemberID.Text);
            memberid = id;
        }

private plusControl_Clicked(...)
{
       string memberId = textBoxMemberId.Text

       Form_Borrowed_Items form2 = new Form_Borrowed_Items(memberId);

       OR

       Form_Borrowed_Items forms = new Form_Borrowed_Items();
       form2.MemberID = memberID;

       //show form2 - Form_Borrowed_Items_Load will be called when showing

}

Here is the code of the Form2 .

public partial class Form_Borrowed_Items : Form
{
       private string _memberId = string.Empty;

       public string MemberID
       {
       get {return _memberId;}
       set { _memberId = value; }
       }

        public Form_Borrowed_Items(string memId)
        {
            InitializeComponent();
	_memberId  = memId; // use _memberId later

        }

        private void Form_Borrowed_Items_Load(object sender, EventArgs e)
       {
            // _memberId value is available here; use it in your query
       }
