DataGridView click event doesn't always fire

问题

I have a DataGridView. Its Cell_Content_Click is not firing each time I select a cell. It does fires but not at each click.

I want to get content of selected cell in my string variable 'selected'. Here is what I am doing:

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value != null)
    {
        selected = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();
    }
}

回答1:

The CellContentClick event only fires when the content (text) inside a cell is clicked.

Use the CellClick event instead of CellContentClick, since that event fires when any part of the cell is clicked (not just the content inside it).
