Here, user will enter employee Id, Name and Salary information in the related textboxes and press “Keep it”. When user press “Keep it” button employee data will be saved to the next Combobox.

So, if user enters three employees information, three employees’ name will be added in the drop down list of Combobox.

After entering several employees’ information, user will select a particular employee from the drop down list of Combobox and press “Show” button, all information (Id, Name, Salary) of the selected employee will be displayed in the messagebox as following format:

Employee Information:
Id:001
name:alman
Salary:1000

    public partial class Form1 : Form

        public Form1()
        {
            InitializeComponent();
        }
        private string id;
        private string name;
        private double salary;
        private void keepItbutton_Click(object sender, EventArgs e)
        {
             id = idtextBox.Text;

make a class Employee like this

class Employee
{
  public string Id;
  public string Name;
  public double Salary; 
}

now take a hash table

HashTable hsEmp=new HashTable();

now change your code as

private void keepItbutton_Click(object sender, EventArgs e)
       {
            Empolyee objEmp=new Employee();
            objEmp.id = idtextBox.Text;
            objEmp.name = nametextBox.Text;
            objEmp.salary =Convert.ToDouble(salarytextBox.Text);
            hsEmp.Add(objEmp.Name,objEmp);
            employecomboBox.Items.Add(name);
      }
       private void showbutton_Click(object sender, EventArgs e)
       {
           Employee objEmp=hsEmp[cboEmp.SelectedValue];
// write code to show employee data;

       }

Class Emp
{
   string id;
   string name;
   doubl sal;
}

namespace WindowsApplicationPraticeOne
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        IDictionary empDic<string,emp> = new Dictionary<string,emp>();
        private void keepItbutton_Click(object sender, EventArgs e)
        {
             Emp temp=new Emp()
             temp.id = idtextBox.Text;
             temp.name = nametextBox.Text;
             temp.salary =Convert.ToDouble(salarytextBox.Text);
             employecomboBox.Items.Add(temp.name);
             empDic.add(temp.id,temp);
       }
        private void showbutton_Click(object sender, EventArgs e)
        {
             Emp temp2 = empDic[employecomboBox.SelectedText.toString()];
//Now you have you can use temp2 class to display data
        }
    }
}

P.S. : I have not compiled and tested the code but should work

private void buttonKeepIt_Click(object sender, EventArgs e)
{
   comboxEmpList.Add.Items(textBoxName.Text);
   //If you are using the database as MySql then use this query to store
   //MySql code: insert into Emptable(id,name,salary) values("18","YYY","28487.87");

}

private void buttonShow_Click(object sender, EventArgs e)
{
    string selectedEmpName = comboboxEmpList.Text;
    //If you are using the database as MySql then use this query to store
    //MySql code: slect * from Emptable where name = selectedEmpName;
    //Use MySql Adapter to get datatable or dataset
     
    textBoxName.Text = dataTable.Rows[0]["name"].ToString();
    textBoxid.Text = dataTable.Rows[0]["id"].ToString(); 
    textBoxSalary.Text = dataTable.Rows[0]["salary"].ToString();
   
}
