问题描述

我想使Web表单只读，因此我需要C#Web应用程序中的代码.

推荐答案

您可以使用以下代码来完成它，因为它更快，因为它有点递归.

You can do it with below code, it is faster because it is somewhat recursive.

EnableControls(this.Page.Form.Controls, false);

public void EnableControls(ControlCollection ctrl, bool isEnable)
       {
           foreach (Control item in ctrl)
           {
               if (item.GetType() == typeof(Panel) || item.GetType() == typeof(HtmlGenericControl))
                   EnableControls(item.Controls, isEnable);
               else if (item.GetType() == typeof(DropDownList))
                   ((DropDownList)item).Enabled = isEnable;
               else if (item.GetType() == typeof(TextBox))
                   ((TextBox)item).Enabled = isEnable;
               else if (item.GetType() == typeof(Button))
                   ((Button)item).Enabled = isEnable;
               else if (item.GetType() == typeof(HtmlInputButton))
                   ((HtmlInputButton)item).Disabled = !isEnable;
           }
       }

为什么在计算后不只是禁用Web窗体的所有控件?

快速浏览Google之后，我发现了以下代码段:

why don''t you just disable all controls of the webform after the calculation?

After a quick Google i found the following snippet:

public void enableAllControls(ControlCollection cc, bool enable)
{
    foreach (Control c in cc)
    {
        try { enableAllControls(c.Controls, enable); } catch { }
        if(c.GetType() == typeof(TextBox)){ try { ((TextBox)c).Enabled = enable; } catch { } }
        else if (c.GetType() == typeof(DropDownList)) { try { ((DropDownList)c).Enabled = enable; } catch { } }
        else if (c.GetType() == typeof(Button)) { try { ((Button)c).Enabled = enable; } catch { } }
        else if (c.GetType() == typeof(LinkButton)) { try { ((LinkButton)c).Enabled = enable; } catch { } }
        else if (c.GetType() == typeof(HtmlInputText)) { try {(HtmlInputText)c).Attributes.Add("disabled", "true"); } catch { } }
    }
}
