Question

当用户点击gridview单元格颜色时会自动更改如果没有点击，所以不要改变gridview的颜色如何解决此问题，并在gridview单元格上设置默认值0

Answer 1

这是在Gridview单元格上设置的默认单元格值

   private void dataGridView1_DefaultValuesNeeded(object sender, DataGridViewRowEventArgs e)
    {

        e.Row.Cells["ship_qty"].Value = (decimal)0;
        e.Row.Cells["packs"].Value = (decimal)1;
    }

这是换色的

 private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            DataGridViewCellStyle CellStyle = new DataGridViewCellStyle();
            CellStyle.BackColor = Color.Red;
            dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Style = CellStyle;
        }

希望这对你有所帮助

Answer 2

试试上面的

  private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
    {
        DataGridViewCellStyle CellStyle = new DataGridViewCellStyle();
        if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Style.BackColor == Color.Red)
        {
            CellStyle.BackColor = Color.White;
            dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Style = CellStyle;
        }
        else
        {

            CellStyle.BackColor = Color.Red;
            dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Style = CellStyle;
        }
    }
