[RESOLVED] Color grouping datagridview rows

i need to group the rows of a datagridview rows basing on values in column1
of DGV.

i mean for example while loop
if .Rows(TOPROW).Cells(0).Value =
.Rows(NextRow).Cells(0).Value then
color the rows with some unique color
else
color them differently

some peace of code pl

Look at the following example

In this example code taken from the project link above if a column named column1 has a length of 4 it gets a new font. Then for you to do the background colors add in your logic in InvokeBanding or ConditionsBandingPrep. Here it is shown in InvokeBanding.

Code:

---

Module DataGridViewExtensions
    Private ConditionalFont As Font = New System.Drawing.Font("Microsoft Sans Serif", 8.25!, _
            System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, CType(0, Byte))
    <System.Diagnostics.DebuggerStepThrough()> _
    <Runtime.CompilerServices.Extension()> _
  Public Sub InvokeBanding(ByVal sender As Windows.Forms.DataGridView)
        For Each band As DataGridViewBand In sender.Rows
            If band.Tag IsNot Nothing Then
                band.DefaultCellStyle.Font = CType(band.Tag, Font)
                band.DefaultCellStyle.BackColor = Color.Cyan
            End If
        Next
    End Sub
    <System.Diagnostics.DebuggerStepThrough()> _
    <Runtime.CompilerServices.Extension()> _
  Public Sub ConditionsBandingPrep(ByVal sender As Windows.Forms.DataGridView)
        For Row As Integer = 0 To sender.Rows.Count - 1
            If sender.Rows(Row).Cells("Column1").Value.ToString.Length = 4 Then
                sender.Rows(Row).Tag = ConditionalFont
            End If
        Next
    End Sub
    <System.Diagnostics.DebuggerStepThrough()> _
    <Runtime.CompilerServices.Extension()> _
  Public Sub ConditionsBandingPrep(ByVal sender As Windows.Forms.DataGridView, _
                                    ByVal Rows As Integer)
        For row As Integer = sender.Rows.Count - 1 To Rows Step -1
            If sender.Rows(row).Cells("Column1").Value.ToString.Length = 4 Then
                sender.Rows(row).Tag = ConditionalFont
            End If
        Next
    End Sub
End Module
