我有一个绑定到DataSource的DataGridView,它根据用户输入将其列隐藏在DataBindingComplete事件中。 它工作正常,除非需要隐藏所有列,始终显示最后一个要隐藏的列。 在调试期间,我可以看到该列设置为visible = false但它没有效果。

我有一个正常的解决方法,在DataBindingComplete事件中触发一个计时器并调用HideColumns()方法,但我正在寻找更好的解决方案。

    private void CoverageDGV_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
    {            
        var datagridview = sender as DataGridView;

        datagridview.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.TopLeft;            
        datagridview.DefaultCellStyle.WrapMode = DataGridViewTriState.True;
        datagridview.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;

        datagridview.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.ColumnHeader;            
        datagridview.RowHeadersVisible = true;            
        datagridview.RowHeadersWidthSizeMode = DataGridViewRowHeadersWidthSizeMode.AutoSizeToDisplayedHeaders;
        datagridview.ColumnHeadersHeightSizeMode = DataGridViewColumnHeadersHeightSizeMode.AutoSize;                                                    
        datagridview.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells;

        HideColumns(datagridview);

        //timer1.Enabled = true; // This works fine
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        timer1.Enabled = false;
        HideColumns(ShipCoverageDGV);
    }

    private void HideColumns(DataGridView datagridview)
    {
        for (int i = 0; i < datagridview.Columns.Count; i++)
        {
            var column = datagridview.Columns[i];
            var itemType = [USER INPUT];
            if (itemType == Glossary.IndirectCOType)
                column.Visible = IndirectCOCheckBox.Checked;
            else if (itemType == Glossary.NotAllocatedType)
                column.Visible = NotAllocatedCheckBox.Checked;
            else
                column.Visible = DirectCOCheckBox.Checked;                    
        }           
    }

我的问题是:如何隐藏所有列?
