VB.net Datagridview cellstyle colors

[Steve]

Hi All

I am using VB.net 2005 professional

I set the background color of a datagridview cell to different colors
depending on many reasons

I set them in the cellformatting event and all works great, i.e the colors
appear as requested
e.g e.CellStyle.BackColor = Color.Red

When I try to read the color in Datagridview.mouseclick event using...
If
dgvgroup.Rows(hit.RowIndex).Cells(hit.ColumnIndex).InheritedStyle.BackColor
= mycolor Then

it always returns false

end if

Note: mycolor = color.salmonpink and actual grid cell color =
color.salmonpink

but
dgvgroup.Rows(hit.RowIndex).Cells(hit.ColumnIndex).InheritedStyle.BackColor
returns color.honeydew which is the defaultcellstyle.backcolor set in

datagridview properties defaultcellstyle in design environment

what am I doing wrong

Regards

Steve

Hi Steve,

When you set the DataGridViewCellFormattingEventArgs.CellStyle.BackColor in
the CellFormatting event handler, you don't change the corresponding cell's
Style.

The DataGridViewCell.InheritedStyle property inherits its value from a
hierarchy of properties of type DataGridViewCellStyle. These properties are
listed below in the order in which the InheritedStyle for non-header cells
obtains its values.

1. System.Windows.Forms.DataGridViewCell.Style
2. System.Windows.Forms.DataGridViewRow.DefaultCellStyle
3. System.Windows.Forms.DataGridView.AlternatingRowsDefaultCellStyle (only
for cells in rows with odd index numbers)
4. System.Windows.Forms.DataGridView.RowsDefaultCellStyle
5. System.Windows.Forms.DataGridViewColumn.DefaultCellStyle
6. System.Windows.Forms.DataGridView.DefaultCellStyle

That's why you get Color.Honeydew from the
'dgvgroup.Rows(hit.RowIndex).Cells(hit.ColumnIndex).InheritedStyle.BackColor
' because the DefaultCellStyle.BackColor is set to Color.Honeydew in your
practice.

If you modify your code as follows, you can get the actual color of the
cell through the InheritedStyle.BackColor property:

Private Sub DataGridView1_CellFormatting(ByVal sender As Object, ByVal e
As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles
DataGridView1.CellFormatting
If (e.RowIndex = 0) Then

Me.DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Style.BackColor =
Color.Red
End If
End Sub

For more information on cell styles in the DataGridView control, you may
refer to the following MSDN document:
'Cell Styles in the Windows Forms DataGridView Control'

Hope this helps.
