I want to show Components in a tabs , so first of all create few components. In this project we have three components, First View Component public class AllViewComponent : ViewComponent { private readonly UserManager<ApplicationUser> _userManager; public AllViewComponent(UserManager<ApplicationUser> userManager) { _userManager = userManager; } public async Task<IViewComponentResult> InvokeAsync() { List<StudentViewModel> allUsers = new List<StudentViewModel>(); var items = await _userManager.Users.ToListAsync(); foreach (var item in items) { allUsers.Add(new StudentViewModel {Id=item.Id, EnrollmentNo = item.EnrollmentNo, FatherName = item.FatherName, Name = item.Name, Age = item.Age, Birthdate = item.Birthdate, Address = item.Address, Gender = item.Gender, Email = item.Email }); }
If you want to get cell value from DataGridview then first to bind grid with data table with any data source. Now, use this code to retrieve the cell value.
{
con.Open();
cmd.CommandText = "select * from [student_record]";
cmd.Connection = con;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
dataGridView1.DataSource = ds;
dataGridView1.DataMember = ds.Tables[0].ToString ();
}
{
string name = dataGridView1.SelectedRows[0].Cells[1].Value.ToString();
MessageBox.Show(name);
Binding Data
private void binddata(){
con.Open();
cmd.CommandText = "select * from [student_record]";
cmd.Connection = con;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
dataGridView1.DataSource = ds;
dataGridView1.DataMember = ds.Tables[0].ToString ();
}
Get cell value on message box
private void button1_Click(object sender, EventArgs e){
string name = dataGridView1.SelectedRows[0].Cells[1].Value.ToString();
MessageBox.Show(name);
}
Code generate the following output
