Datagrid Scrollbar

Datagrid Scrollbar

  Use the readonly property which would set the grid so you could enter or chnage anything but the scrollbars would still be active enabling you to scroll around and view the data.

  Thanks for your reply,

  but the problem is that I need to close the Datagrid so the user can'nt choose another row for some minutes to make changes in other data in textboxs

  the readonly property stop editing but the user can still move between the rows

  if the user change the row , it will change the data in textboxs

  You can still use the readonly - but you have to code around it a little. In my example I have a button which I can disable further changes to be made and whilst it disallows changes to be made the selected value remains but it allows me to scroll around the grid and the values are readonly - when I reclick the button to reenable selection of rows then editing is re-enabled.

  You just have to maintain the selected item you want to preserve and handle this.

  Example

  Public Class Form1
  Dim blnNoChnage As Boolean = False
  Dim selrow As Integer '//Currently Selected Row

  Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
  '//Populate the datagridview
  Dim dt As New DataTable
  dt.Columns.Add("1")
  dt.Columns.Add("2")

  dt.Rows.Add(1, 2)
  dt.Rows.Add(2, 2)
  dt.Rows.Add(3, 2)
  dt.Rows.Add(4, 2)
  Me.DataGridView1.DataSource = dt

  
  Me.DataGridView1.MultiSelect = False
  Me.DataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect
  End Sub

  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
  blnNoChnage = Not blnNoChnage '//Toggles between allow or not allowing selected row to be changed
  Me.DataGridView1.ReadOnly = blnNoChnage
  End Sub

  Private Sub DataGridView1_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGridView1.SelectionChanged
  If Me.DataGridView1.SelectedRows.Count > 0 Then
  '// If no chnage allowed then reset the selected row back to what it should be
  '// else allow the chnage to take place and update the selrow variable
  If blnNoChnage = True Then
  CType(sender, DataGridView).Rows(selrow).Selected = True
  Else
  selrow = CType(sender, DataGridView).CurrentRow.Index
  End If
  Label1.Text = Me.DataGridView1.SelectedRows(0).Cells(0).Value

  End If
  

  End Sub
  End Class
