I have 2 dgvws on 2 forms. The first dgvw has a checbox column.I want to copy the checked rows from dgvw 1 to dgvw 2..without any button click..i mean the rows will copy themselves as soon as the user checks a row's checkbox...

What I have tried:

I am using the below code :

VB
Private Sub userdatagrid_SelectionChanged(sender As Object, e As EventArgs) Handles userdatagrid.SelectionChanged
       Dim c, t As Integer
       Selected.dg2.Columns.Clear()
       For t = 0 To userdatagrid.Columns.Count - 1
           Selected.dg2.Columns.Add(userdatagrid.Columns(t).Clone())
       Next
       For c = 0 To userdatagrid.Rows.Count - 1
           If userdatagrid.Rows(c).Cells(0).Value = True Then
               Selected.dg2.Rows.Add(userdatagrid.Rows(c).Cells(0).Value, userdatagrid.Rows(c).Cells(1).Value, userdatagrid.Rows(c).Cells(2).Value, userdatagrid.Rows(c).Cells(3).Value, userdatagrid.Rows(c).Cells(4).Value, userdatagrid.Rows(c).Cells(5).Value, userdatagrid.Rows(c).Cells(6).Value, userdatagrid.Rows(c).Cells(7).Value, userdatagrid.Rows(c).Cells(8).Value, userdatagrid.Rows(c).Cells(9).Value, userdatagrid.Rows(c).Cells(10).Value, userdatagrid.Rows(c).Cells(11).Value, userdatagrid.Rows(c).Cells(12).Value, userdatagrid.Rows(c).Cells(13).Value, userdatagrid.Rows(c).Cells(14).Value, userdatagrid.Rows(c).Cells(15).Value, userdatagrid.Rows(c).Cells(16).Value, userdatagrid.Rows(c).Cells(17).Value, userdatagrid.Rows(c).Cells(18).Value, userdatagrid.Rows(c).Cells(19).Value, userdatagrid.Rows(c).Cells(20).Value, userdatagrid.Rows(c).Cells(21).Value, userdatagrid.Rows(c).Cells(22).Value, userdatagrid.Rows(c).Cells(23).Value, userdatagrid.Rows(c).Cells(24).Value, userdatagrid.Rows(c).Cells(25).Value, userdatagrid.Rows(c).Cells(26).Value, userdatagrid.Rows(c).Cells(27).Value, userdatagrid.Rows(c).Cells(28).Value, userdatagrid.Rows(c).Cells(29).Value, userdatagrid.Rows(c).Cells(30).Value)
           End If
       Next
   End Sub

  Private Sub form2_load(sender As Object, e As EventArgs) Handles MyBase.Load
       Dim img As DataGridViewImageColumn
       img = dg2.Columns(1)
       img.ImageLayout = DataGridViewImageCellLayout.Stretch
   End Sub
  Private Sub Button6_Click(sender As Object, e As EventArgs) Handles Button6.Click
       Selected.Show()
   End Sub

hello, i am using this code now :

Private Sub userdatagrid_SelectionChanged(sender As Object, e As EventArgs) Handles userdatagrid.SelectionChanged
Dim c, t As Integer
Selected.dg2.Columns.Clear()
For t = 0 To userdatagrid.Columns.Count - 1
Selected.dg2.Columns.Add(userdatagrid.Columns(t).Clone())
Next
For c = 0 To userdatagrid.Rows.Count - 1
If userdatagrid.Rows(c).Cells(0).Value = True Then
Selected.dg2.Rows.Add(userdatagrid.Rows(c).Cells(0).Value, userdatagrid.Rows(c).Cells(1).Value, userdatagrid.Rows(c).Cells(2).Value, userdatagrid.Rows(c).Cells(3).Value, userdatagrid.Rows(c).Cells(4).Value, userdatagrid.Rows(c).Cells(5).Value, userdatagrid.Rows(c).Cells(6).Value, userdatagrid.Rows(c).Cells(7).Value, userdatagrid.Rows(c).Cells(8).Value, userdatagrid.Rows(c).Cells(9).Value, userdatagrid.Rows(c).Cells(10).Value, userdatagrid.Rows(c).Cells(11).Value, userdatagrid.Rows(c).Cells(12).Value, userdatagrid.Rows(c).Cells(13).Value, userdatagrid.Rows(c).Cells(14).Value, userdatagrid.Rows(c).Cells(15).Value, userdatagrid.Rows(c).Cells(16).Value, userdatagrid.Rows(c).Cells(17).Value, userdatagrid.Rows(c).Cells(18).Value, userdatagrid.Rows(c).Cells(19).Value, userdatagrid.Rows(c).Cells(20).Value, userdatagrid.Rows(c).Cells(21).Value, userdatagrid.Rows(c).Cells(22).Value, userdatagrid.Rows(c).Cells(23).Value, userdatagrid.Rows(c).Cells(24).Value, userdatagrid.Rows(c).Cells(25).Value, userdatagrid.Rows(c).Cells(26).Value, userdatagrid.Rows(c).Cells(27).Value, userdatagrid.Rows(c).Cells(28).Value, userdatagrid.Rows(c).Cells(29).Value, userdatagrid.Rows(c).Cells(30).Value)
End If
Next
End Sub

Private Sub form2_load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim img As DataGridViewImageColumn
img = dg2.Columns(1)
img.ImageLayout = DataGridViewImageCellLayout.Stretch
End Sub
Private Sub Button6_Click(sender As Object, e As EventArgs) Handles Button6.Click
Selected.Show()
End Sub
The problem with this code is, if i check only one row/checkbox and click on button 6, the dgvw on form 2 appears to br rmpty. I need to select/check two rows and then only one of the rows appear. The second problem is, suppose a user checks only one checkbox, and clicks on the button , the dgv on form 2 is empty(i said that already) but if the user closes form 2 and reopens it with button6, it gives an INDEX OUT OF RANGE exception in form 2's IMG=DG2.COLUMNS(1) ....how to fix these problems ??
