    Dynamic DataGridView missing horizontal scrollbar

    Hi,

    I am dynamically creating datagridviews for my application, then
    filling them with data from a 30 row datatable, and everything seems to
    work great with one exception. My horizontal scrollbar never appears --
    no problem with the vertical scrollbar. I even try setting the
    scrollbars property to Both, but still I only see the vertical
    scrollbar.

    Is there any other way to force the DataGridView's vertical scrollbar
    to appear?????

    Thanks,

    Crazy

          Doesn't work -- I used datagridview.cu rrentrow.cells( INDEX).selected =
          true but no dice.

          Any other ideas?

          Thanks

              uhm.. ok.., And you do have more than the visible area of columns, still not
              getting scrollbars.. are u using 2.0 or 1.1 ?

                  Crazy,

                  With this code I see a vertical and a horizontal scrollbar

                  \\\
                  Dim mydatagridview As New DataGridView
                  Controls.Add(my datagridview)
                  mydatagridview. DataSource = MyEmployeesBind ingSource
                  ///

                  I hope this helps,

                  Cor

                      I'm pretty sure I'm using 2.0. I do have more than the visible area of
                      columns -- almost twice as much.

                      Thanks,

                          I don't have a binding source because I don't use the DataSet designer
                          to get the tables back. Perhaps that'll help? I'll take a look and post
                          back.

                          Thanks,

                              OK,

                              I tried this again with the Binding Source and still no scrollbar --
                              does anyone have any other ideas???? PLEASE???

                              Here's the code --


                              Dim tabDetails As TabPage
                              Dim DetailsBindingS ource As BindingSource
                              Dim dgvDetails As DataGridView

                              tctlDetails.Tab Pages.Clear()
                              If PortDetailsData Set IsNot Nothing Then
                              For Each dt As System.Data.Dat aTable In
                              PortDetailsData Set.Tables

                              Me.tctlDetails. TabPages.Add(dt .Rows(0).Item(" MSC_NAME"))
                              tabDetails =
                              tctlDetails.Tab Pages(tctlDetai ls.TabPages.Cou nt - 1)
                              dgvDetails = New DataGridView()
                              With dgvDetails
                              .Visible = True
                              .AllowUserToAdd Rows = False
                              .AllowUserToDel eteRows = False
                              DetailsBindingS ource = New
                              BindingSource(P ortDetailsDataS et, dt.TableName)
                              .DataSource = DetailsBindingS ource
                              tabDetails.Cont rols.Add(dgvDet ails)
                              dgvDetails.Dock = DockStyle.Fill
                              dgvDetails.Scro llBars =
                              System.Windows. Forms.ScrollBar s.Both
                              For Each a As DataGridViewCol umn In .Columns
                              a.ReadOnly = True
                              Next
                              .ScrollBars = System.Windows. Forms.ScrollBar s.Both
                              End With
                              Next
                              End If

                              BTW, on a side note I allow the user to clear the tabs from the
                              tabcontrol assuming that because the dynamic bindingsources and
                              datatables are no longer referenced the VS garbage collecter will clean
                              them up. Is that a correct assumption or should I delete the referenced
                              objects myself?

                              Thanks,

                              Crazy

                                  Crazy Cat,

                                  Because that I see "Dock Fill" are you sure that your DataGridView is narrow
                                  enough to show the horizontal scrollbar?

                                  Cor

                                      It should be, even when the application is maximized I can only see
                                      about 50 - 60 % of the columns.

                                      Thanks,
