That's it.
I need to highlights ID-1 all rows to Yellow Color
Then 2 to Lime Color.
And 3 to Yellow Again.

Here is my Code But Not working. Any Help will be really appreciated.
For i As Integer = 0 To dgvvoucher.Rows.Count - 1
                For j As Integer = 0 To dgvvoucher.Rows.Count - 1
                    If dgvvoucher.Item(0, i).Value = dgvvoucher.Item(0, i).Value Then
                        dgvvoucher.Rows(i).DefaultCellStyle.BackColor = Color.Yellow
                    Else
                        dgvvoucher.Rows(i).DefaultCellStyle.BackColor = Color.Lime
                    End If
                Next
            Next

Thank you for replying sir ..
but it's no for my question ..

My dgv is 5 column show in attach
i want to only highlight the row by ID value.

Data is Preloading As Shown in Picture .
When i click the button ...

All rows of Number 1 are yellow.
All rows of Number 2 are lime.
And
All rows of Number 5 are yellow again.

How to code ?

I think it may using like For method with Step - 1 ?
But i'm not coded.

Sorry for my english . Thank you.

Perhaps try something like this:

// walk through rows of dgv with for-loop
            if (Convert.ToInt32(row.Cells[0].Value) == 1) //ID of first column equals 1
            {
                row.DefaultCellStyle.BackColor = Color.Red;
            }
            else if(Convert.ToInt32(row.Cells[0].Value) == 1)
            { 
                row.DefaultCellStyle.BackColor = Color.Green; 
            }

Please change Cells[0].Value to Cells(0).Value
Perhaps a for each ... next loop is more appropriate also.

' walk through rows of dgv with for-loop
If Convert.ToInt32(row.Cells(0).Value) = 1 Then
    'ID of first column equals 1
    row.DefaultCellStyle.BackColor = Color.Red
ElseIf Convert.ToInt32(row.Cells(0).Value) = 1 Then
    row.DefaultCellStyle.BackColor = Color.Green
End If

I write with VB.NET but I don't know what is mean 'row'
it cause error.
Thanks again.
