hi, i am having a table in the datagridview with six columns. the last column is a checkbox type. I want to delete the rows from the table with the checkbox ticked on the click of a button. Since i am a beginner with vb.net, I would greatly appreciate any help in this in the form of the syntax format.

Try something like this:

Public Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
      For Each m_row as System.Windows.Forms.DataGridViewRow in me.DataGridView1.Rows
         If m_row.Cells("Column1").Value=True Then    
        End If
End Sub

Column1 is the column where you have the CheckBox. This code only deletes the row from the DataGridView. If the DataGridView is bound to a table and you want to remove the record from the table check this post:


Hope this helps you,

I got a weird problem now with this operation. Let's say I have 3 data rows in the datagridview. If i select the first or the last row to delete, it deletes them properly. however, if i select any middle row other than the ones on the ends, the remove operations deletes all the rows except the row selected to be deleted.

Also, once i delete a row, how do i update the datagridview to reflect the change?

Private Sub RemoveSelected_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
        Dim response As DialogResult = MessageBox.Show("Are you sure you want to delete the selected ticket(s)?", "Delete row?", MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2)
        If (response = DialogResult.No) Then
            Exit Sub
            For Each m_row As System.Windows.Forms.DataGridViewRow In Me.DataGridView1.Rows
                If m_row.Cells("Column6").Value = True Then
                End If
        End If
    End Sub

Ignore the above comment, I got it working. I was referencing the wrong column number!

My mistake!
