[RESOLVED] DataGridView FullRowSelect selects column header too

[squatman]

Hi there,

I've used many DataGridViews and never come across this problem.

When I set the SelectionMode to "FullRowSelect", the full row shows as selected as you'd expect, but the ColumnHeader of the actual Cell clicked also shows as selected.

A solution that stops this happening is to set EnableHeaderVisualStyles to False, but then this removes the highlighting of a Column Header when the cursor hovers over it, which I want.

I've married up the same settings from another project where this isn't happening, and it's still happening.

Any help would be appreciated.

Thank you.

You mean the RowHeader is always selected when the full row is selected? That's the default behaviour for a DGV

Looks like you'll have to do some conditional formatting on the fly...

Private Sub DataGridView1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DataGridView1.MouseMove
    'The rowheader column's ColumnIndex is -1
    Debug.Print(DataGridView1.HitTest(e.X, e.Y).ColumnIndex.ToString)
End Sub

Paul,

Thank you for your response.

No I meant as I wrote the Column Header appears selected.

Please see attached images showing the cell I click (see mouse cursor), the Row shows as selected, but also the corresponding column header does.

The final image shows the header highlight on hover, I would like to retain this functionality.

Thank you.

Luckily I've managed to find the solution here:

You need to add the following code to the "app.config" file:

<runtime>
        <AppContextSwitchOverrides value="Switch.UseLegacyAccessibilityFeatures=false;Switch.UseLegacyAccessibilityFeatures.2=true" />
    </runtime>
