取消选择DataGridView上的所有行

Question

Does anybody know how to unselect ALL the rows on a Windows Forms DataGridView control? By default, the first row is always selected...
Also, I don't want to allow any kind of selection, do you guys know any method to this?

I've already searched here but can't find...

Any help would be great!

Edit: Ok, I've found another way to unselect a row: on the DataGridViewRow.RowPostPaint() event, use the Selected property to unselect the row who sent the event.

private void grid_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
{
    this.gridLogEntries.Rows[e.RowIndex].Selected = false;
}

I don't think there's a simple solution like DisableSelection = true .

Anyway, handling SelectionChanged event in the following way, should be enough:

private bool skipEvents;

void dataGridView1_SelectionChanged(object sender, EventArgs e)
{
    if (skipEvents)
        return;

    skipEvents = true;

    // disable cell selection
    foreach (DataGridViewCell cell in this.dataGridView1.SelectedCells)
        cell.Selected = false;
    // disable row selection
    foreach (DataGridViewRow row in this.dataGridView1.SelectedRows)
        row.Selected = false;
    // disable column selection
    foreach (DataGridViewColumn col in this.dataGridView1.SelectedColumns)
        col.Selected = false;

    skipEvents = false;
}

EDIT:

I slightly changed the code to avoid recursive calls of the method.

Answer 2

datagridview1.clearselection()

这将只在一个语句中解决问题，无需循环

Answer 3

尝试禁用tabstop选项，这对我来说是一个类似的问题

Answer 4

你试过这个吗？

myTable.CurrentRowIndex = -1;

You could try calling the unselect method for each selected row:

        for (int i = 0; i < bindingSource1.Count; i++)
        {
            if (myGrid.IsSelected(i))
            {
                myGrid.UnSelect(i);
            }
        }
