A color for each instrument is stored in the database.  i need to change the cell background base on the instrument color assignment.
Instrument1 color.lightGray
Instrument2 color.yellow
Instrument3 color.Blue

Celle(17) has the value "color.Blue"  which of couse is a string

 Me.dgvJobStatusHistory.Rows(e.RowIndex).Cells(3).Style.BackColor = Me.dgvJobStatusHistory.Rows(e.RowIndex).Cells(17).Value

Error:  Specific cast is invalid.

Any suggestions on how to store of convert would be appreciated.

pre define your colors in a dictionary and set them from there, e.g

            Dim ColorDICT As New Dictionary(Of String, Color) From {{"color.yellow", Color.Yellow}, {"color.Blue", Color.Blue}, {"color.lightGray", Color.LightGray}}
            Me.dgvJobStatusHistory.Rows(e.RowIndex).Cells(3).Style.BackColor = ColorDICT.Item(Me.dgvJobStatusHistory.Rows(e.RowIndex).Cells(17).Value)

Open in new window

you can use
 If (Me.dgvJobStatusHistory.Rows(e.RowIndex).Cells(17).Value = "color.yellow") Then
            Me.dgvJobStatusHistory.Rows(e.RowIndex).Cells(3).Style.BackColor = System.Drawing.Color.Red
        ElseIf (Me.dgvJobStatusHistory.Rows(e.RowIndex).Cells(17).Value = "color.Gray") Then
            Me.dgvJobStatusHistory.Rows(e.RowIndex).Cells(3).Style.BackColor = System.Drawing.Color.Red
        ElseIf (Me.dgvJobStatusHistory.Rows(e.RowIndex).Cells(17).Value = "color.Red") Then
            Me.dgvJobStatusHistory.Rows(e.RowIndex).Cells(3).Style.BackColor = System.Drawing.Color.Red
        End If

I do not really want to code for every color.  Previous solution from (nepaluz) works best for me.
