Hi Experts,

I have a datagridview. When I click on a cell it highlights with the highlight color. I have tried to disable this by using clearselection(). However it still shows just for the mouse down event. I tried to use the following:

dgvInvoices.CurrentCell.Selected = False

This didnt work...

Any ideas??

Hi Lex,

I have created the DGV programmatically and didnt use the option you have displayed above..

I am applying a binding source via code. I have included the full sub below.

There must be an easy way to drive this... I also tried to set the background selection color to white but that also didnt work...

Greetings

this did work for me, altough I did not bind to datasource, don't know if it behaves differently if done so. Need to do this for each column.

:)
Lex
Dim mystyle As New DataGridViewCellStyle
 
mystyle.SelectionBackColor = Color.White
mystyle.SelectionForeColor = Color.White
 
Column1.DefaultCellStyle = mystyle

Hi si2030

Have you tried this? I hope this be some help to your need.

 Private Sub dgvInvoices_CellMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles dgvInvoices.CellMouseClick
    If e.Button = MouseButtons.Left Then
       dgvInvoices.CurrentCell = Nothing
   End If
 End Sub
