Question

Operation is not valid because it results in a reentrant call to the setcurrentcellAddressCore Function

Asked by: AlHal2

I have a datagridview in VB2005.  I've got the sourcecode on my local machine and have copied the executable to the local drive of a server.
If I double click on a rowheader in the grid I call this event below.
Then I double click on one of the cells in the grid.
Then I exit the SuppliedFileChange_Load form and return to the SuppliedFile form.
If I then double click on another rowheader in the grid I get the error message which is the title of the question.

This only happens when I run the executable.  It does not happen when I run the source code.
Any ideas?

Private Sub Grid2_RowHeaderMouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles Grid2.RowHeaderMouseDoubleClick
        SuppliedFileChange.ShowDialog()
    End Sub 
 
Private Sub SuppliedFileChange_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
        Grid3.Height = Me.Height - (Grid3.Top * 1.5)
        Grid3.Width = Me.Width * 15 / 16
        lblUpdate.Top = Grid3.Bottom
 
        Me.Top = rect.Height / 2
        Me.Height = rect.Height / 2
        Me.Left = rect.Left
        i = SuppliedFile.Grid2.CurrentRow.Index
        cmd1.Connection = con1
        cmd1.CommandText = "xxx"
        cmd1.CommandType = CommandType.StoredProcedure
        cmd1.Parameters.Clear()
        cmd1.Parameters.AddWithValue("@SuppliedfileID", SuppliedFile.Grid2(17, i).Value())
        cmd1.ExecuteNonQuery()
 
        adapter.SelectCommand = cmd1
 
        dt.Clear()
        adapter.Fill(dt)
        For Each dr In dt.Rows
            StatusCodeFlag = dr("StatusCode").ToString.Trim
        Next
        If StatusCodeFlag = "CONF" Or StatusCodeFlag = "PRIF" Then
            cmdResetToRecv.Enabled = True
        Else
            cmdResetToRecv.Enabled = False
        End If
        'End Using
        Grid3.DataSource = dt
        Grid3.Columns(15).Visible = False
        Grid3.Columns(16).Visible = False
        Grid3.Columns(17).Visible = False
        ColorMyGrid()
 
        lblserver.Text = "You are connected to " & connectionString
        cCmd.Dispose()
 
    End Sub

Maybe error because a read-only cell of datagrid is being focused. Try to add following code to prevent from that cell focusing

Private Sub Grid2_CellEnter(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs) Handles Grid2.CellEnter
    Dim dgv As DataGridView = DirectCast(sender, DataGridView)
    ' Check for readonly cell. If so then force move to next cell
    If dgv.Rows(e.RowIndex).Cells(e.ColumnIndex).ReadOnly Then 
        SendKeys.Send("{TAB}") 
    End If
End Sub

No difference.
I wonder if it's to do with security settings.  Bear in mind the source code is fine, but the executable is where the problem lies.

Any ideas?

Sorry, I have no idea.

However, if you copy the error string to google search you will get lots of links to forums. Almost of the say the same that is a read-only cell is being focused/edited and the solution is moving the focus to the next writable cell during the read-only cell is entered.
