以编程方式隐藏DataGridView列位置0和1

Question

我试图将位置0和1的可见性设置为false

我的代码：

                    mainContenttabControl.TabPages.Add(myTabPage);
                    mainContenttabControl.TabPages[i].Controls.Add(new DataGridView()
                    {
                        Name = "dataGridView_" + tabTitle,
                        Dock = DockStyle.Fill,
                        DataSource = selectedSensors,
                        AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill,
//SET HERE COLUMN VISIBLITY = false
                    });

但是我不能在这里访问属性.Column，我也尝试编写一个函数，该函数在我的“ setDataGridViews（）”函数之后被调用，但仅在已加载窗体时才起作用

private void hideDatalayerColumns()
        {
            int dataGridViewHardwareIndex = mainContenttabControl.TabPages[0].Controls.IndexOfKey("dataGridView_" + "Hardware");
            int dataGridViewSensorsIndex = mainContenttabControl.TabPages[1].Controls.IndexOfKey("dataGridView_" + "Sensors");
            int dataGridViewServiceIndex = mainContenttabControl.TabPages[2].Controls.IndexOfKey("dataGridView_" + "Service");
            int dataGridViewRepairIndex = mainContenttabControl.TabPages[3].Controls.IndexOfKey("dataGridView_" + "Repair");

            if (dataGridViewHardwareIndex >= 0)
            {
                DataGridView myTabGridViewHardware = mainContenttabControl.TabPages[0].Controls[dataGridViewHardwareIndex] as DataGridView;
                myTabGridViewHardware.Columns[0].Visible = false;
                myTabGridViewHardware.Columns[1].Visible = false;
            }
            if (dataGridViewSensorsIndex >= 0)
            {
                DataGridView myTabGridViewSensors = mainContenttabControl.TabPages[1].Controls[dataGridViewSensorsIndex] as DataGridView;
                myTabGridViewSensors.Columns[0].Visible = false;
                myTabGridViewSensors.Columns[1].Visible = false;
            }
            if (dataGridViewServiceIndex >= 0)
            {
                DataGridView myTabGridViewService = mainContenttabControl.TabPages[2].Controls[dataGridViewServiceIndex] as DataGridView;
                myTabGridViewService.Columns[0].Visible = false;
                myTabGridViewService.Columns[1].Visible = false;
            }
            if (dataGridViewRepairIndex >= 0)
            {
                DataGridView myTabGridViewRepair = mainContenttabControl.TabPages[3].Controls[dataGridViewRepairIndex] as DataGridView;
                myTabGridViewRepair.Columns[0].Visible = false;
                myTabGridViewRepair.Columns[1].Visible = false;
            }
        }

是否有解决方法或更好的解决方案，即我的两列为.Visible = false？

有趣的部分是它在那里...

Answer 1

如果您想隐藏Form中几个DGV的前两列，那么我可以使用下面的Linq递归函数返回DGV并隐藏目标列：

private IEnumerable<DataGridView> GetAllDGVs(Control container)
{
    var controls = container.Controls.Cast<Control>();
    return controls.SelectMany(c => GetAllDGVs(c))
        .Concat(controls.OfType<DataGridView>());
}

和用法：

private void hideDatalayerColumns()
{
    GetAllDGVs(this).ToList().ForEach(dgv =>
    {
        dgv.Columns[0].Visible = false;
        dgv.Columns[1].Visible = false;
    });
}

祝好运。
