I have a datagridview whose datasource is an entity collection.I can load the values of the selected rows into different textboxes using the datagridview SelectionChanged events.Below is the code that i am using.

SQL

Dim selectedUser = DirectCast(Me.grdShowOfficers.CurrentRow.DataBoundItem, Exams_Officer)
       txtTitle.Text = selectedUser.Title
       txtFirst.Text = selectedUser.First_Name
       txtLastName.Text = selectedUser.Last_Name
       txtFaculty.Text = selectedUser.Faculty.Faculty_Name
       txtDepartment.Text = selectedUser.Department.Department_Name
       txtProgramme.Text = selectedUser.Programme
       txtPhoneNumber.Text = selectedUser.Phone_Number
       dateAppointment.Text = selectedUser.Appointment_Date

It works fine.The problem is that when i change the values of the textbox it is not showing the edited values on the datagridview when i call the entity saveChanges() method from a button click event.I know i am doing something wrong please i need help.This is the button click event.

Dim selectedRow As Int32 = Me.grdShowOfficers.Rows.GetFirstRow(DataGridViewElementStates.Selected)

SQL

selectedrow.Title = txtTitle.Text
selectedUser.First_Name = txtFirst.Text
selectedUser.Last_Name() = txtLastName.Text
'selectedUser.Faculty.Faculty_Name = txtFaculty.Text
'selectedUser.Department.Department_Name = txtDepartment.Text
selectedUser.Programme = txtProgramme.Text
selectedUser.Phone_Number = txtPhoneNumber.Text
selectedUser.Appointment_Date = CType(dateAppointment.Text, Date)
    examinationOfficer.SaveChanges()

when i do these (the below code ) on the datagridview contentdouble click event

VB

txtTitle.Text = grdShowOfficers.Item("Title", grdShowOfficers.CurrentRow.Index).Value.ToString()
      txtFirst.Text = grdShowOfficers.Item("First_Name", grdShowOfficers.CurrentRow.Index).Value.ToString()
      txtLastName.Text = grdShowOfficers.Item("Last_Name", grdShowOfficers.CurrentRow.Index).Value.ToString()
      txtProgramme.Text = grdShowOfficers.Item("Programme", grdShowOfficers.CurrentRow.Index).Value.ToString()
      txtPhoneNumber.Text = grdShowOfficers.Item("Phone_Number", grdShowOfficers.CurrentRow.Index).Value.ToString()
      dateAppointment.Text = grdShowOfficers.Item("Appointment_Date", grdShowOfficers.CurrentRow.Index).Value.ToString()

and this button click event before calling savechanges

VB

grdShowOfficers.CurrentCell.Value = txtTitle.Text

        grdShowOfficers.CurrentCell.Value = txtLastName.Text

        grdShowOfficers.CurrentCell.Value = txtFirst.Text

        grdShowOfficers.CurrentCell.Value = txtProgramme.Text

        grdShowOfficers.CurrentCell.Value = txtPhoneNumber.Text

        grdShowOfficers.CurrentCell.Value = dateAppointment.Text

only the first cell of the selected datagridview row is updated and the value it gets is the value of the last cell which is suppose to be updated by the dateappointment.text textbox.Please help

Please use the "Improve question" widget and add the snippet of the button where you call the saveChanges. It might give some information about what you are missing

In your button click event you are using

VB

grdShowOfficers.CurrentCell.Value = ....Text

for all of your updates.
Try using something like

VB

grdShowOfficers.CurrentRow.Cells("Last_Name").Value = txtLastName.Text

etc etc
