WinForms - DataGridView - no cell selected

Question

Is there a way to make a DataGridView have no cell selected? I notice even when it loses focus() it has a at least one active cell. Is there another mode that allows this? or some other trick?

Answer 1

DataGridView.CurrentCell property can be used to clear the focus rectangle.

You can set this property (DataGridView.CurrentCell) to null to temporarily remove the focus rectangle, but when the control receives focus and the value of this property is null, it is automatically set to the value of the FirstDisplayedCell property.

Answer 2

I found that the DataGridView.CurrentCell = null didn't work for me when trying to get the requested behaviour.

What I ended up using was:

    private void dgvMyGrid_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
    {
        if (dgvMyGrid.SelectedRows.Count > 0)
        {
            dgvMyGrid.SelectedRows[0].Selected = false;
        }

        dgvMyGrid.SelectionChanged += dgvMyGrid_SelectionChanged;
    }

It needed to be in the DataBindingComplete event handler.

Where you attach the SelectionChanged event handler doesn't affect the desired behaviour but I left it in the code snippet because I noticed for my needs at least it was better to only attach the handler after databinding, so that I avoid a selection changed event being raised for each item bound.

I spent hours to find the solution for this problem. Do this:

1. Create a Form Project
2. Add a DataGridView with the name "DataGridView1"

3. Add the following code to your class Form1

   Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
   
   
   Dim dgvRow(17) As DataGridViewRow
   Dim i As Integer
   For i = 0 To dgvRow.Length - 1
       dgvRow(i) = New DataGridViewRow()
       dgvRow(i).Height = 16
       dgvRow(i).Selected = False
       dgvRow(i).ReadOnly = True
       DataGridView1.Rows.Add(dgvRow(i))
       DataGridView1.CurrentRow.Selected = False
   Next
   End Sub
   

The importaint line of code is

    DataGridView1.CurrentRow.Selected = False

Good luck!
