I am Using a checkbox column in datagrid view.
On checking the checkbox of a particular row I want to set the back color of that row to different color and on uncheck, back to white.
On which event of datagrid should I write the code?

And one more thing how to get value of checked state of checkbox i.e. whether it is checked or not (true or false) in any event of datagrid?

Hoping for a solution.

Hi Manoj,

On cell content click.

C#

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            if (e.RowIndex != -1)
            {
                if (e.ColumnIndex != 1)
                {
                    if (dataGridView1.Columns[e.ColumnIndex].Name = "colCheckBox")
                    {
                        if ( Convert.ToBoolean (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value == true )
                        {
                            //do this
                        }
                        else
                        {
                            //do do that
                        }
                    }
                }
            }
        }

You want this?

VB

Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged
  If e.RowIndex < 0 Or e.ColumnIndex < 0 Then Exit Sub
  If e.ColumnIndex = 0 Then
    If DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value Then
      For Each c As DataGridViewCell In DataGridView1.Rows(e.RowIndex).Cells
        c.Style.BackColor = Color.Black
      Next
    Else
      For Each c As DataGridViewCell In DataGridView1.Rows(e.RowIndex).Cells
        c.Style.BackColor = Color.White
      Next
    End If
  End If
End Sub

I got the answer on cell content click i made an object of that cell and coded further like.....

SQL

Dim oCheck As DataGridViewCheckBoxCell
oCheck = datagrid.CurrentRow.Cells("colunmname")

SQL

If oCheck.EditingCellFormattedValue = True Then
 For iCount = 0 To datagrid.CurrentRow.Cells.Count - 1
  datagrid.CurrentRow.Cells(iCount).Style.BackColor = Color.Teal
 Next iCount
Else
 For iCount = 0 To datagrid.CurrentRow.Cells.Count - 1
  datagrid.CurrentRow.Cells(iCount).Style.BackColor = Color.White
  Next iCount
End If
