Set background color of current row in vb.net (aspx) loop

Question

I am trying to loop through all rows on my GridView1 and change the backgournd colour of the rows as they are processed.

The loop works perfectly, but for some reason the line of code to set the Back Color is not being honoured.

nextRow.BackColor = System.Drawing.Color.RoyalBlue

Here is the complete loop.

For i As Integer = 0 To GridView1.Rows.Count - 1

    Dim counter As Integer = GridView1.SelectedIndex + 1
    Dim nextRow As GridViewRow

    nextRow = GridView1.Rows(0)
    If counter = GridView1.Rows.Count Then
        nextRow = GridView1.Rows(0)

    Else

        'formatting
        nextRow.BackColor = System.Drawing.Color.RoyalBlue

        nextRow = GridView1.Rows(counter)
        CompileHTML(GridView1.Rows(i))
        ExportHTML(GridView1.Rows(i))

    End If
Next

Answer 1

Your are setting the value of nextRow to the first row directly above the if statement so nextRow is always GridView1.Rows(0) when backcolor is set.

For Each row As GridViewRow In GridView1.Rows
    row.BackColor = System.Drawing.Color.RoyalBlue
Next
