            if (RadioButtonList1.SelectedValue == "2")
            {
                drp_Week.Enabled = false;
                gv_Details.Visible = false;
                panel_rmv.Visible = false;
                pnl_DetailsGeneral.Visible = true;//Here when i put a break point and after setting visible to true i find `pnl_DetailsGeneral.Visible = false`
                gv_DetailsGeneral.Visible = true;
                BindGridGeneral();

            }
            else if (RadioButtonList1.SelectedValue == "1")
            {
                drp_Week.Enabled = true;
                gv_Details.Visible = true;
                gv_DetailsGeneral.Visible = false;
                pnl_DetailsGeneral.Visible = false;
                if (drp_Week.SelectedValue != "-1")
                {

                    BindGrid();
                }
            }
        }

推荐答案

Visible属性有一个特殊的属性：当你阅读的价值，它不仅报告了控制本身，还对其父。你得到的值是真正的知名度。

The Visible property has a special property: when you read the value it not only reports on the control itself but also on it's parent. The value you get is the "real" visibility.

因此​​很明显，你控制的母公司仍然是看不见的！

So apparently the parent of your control is still invisible!

当你设置父可见，你的控制将成为也是可见的。

When you set the parent to Visible, your control will become visible also.
