问题描述

以下代码可以很好地禁用内容页面控件，但是如何禁用母版页面控件?

The following code works fine for disabling content page controls, but how do I disable master page controls?

public void DisableControls(Control control,bool isEnable)
{
    if (control.HasControls())
    {
        foreach (Control c in control.Controls)
        {
            DisableControls(c, isEnable);
        }
    }
    else
    {
        if (control is IPostBackDataHandler && !(control is IPostBackEventHandler))
        {
            if (control is WebControl)
            {
                ((WebControl)control).Enabled = isEnable;
            }
            else if (control is HtmlControl)
            {
                ((HtmlControl)control).Disabled = !isEnable;
            }
        }
    }
}

推荐答案

如果要禁用母版页上的所有控件，只需执行以下操作:

If you want to disable all the controls on a Master Page, just do the following:

DisableControls(this.Page.Master, isEnable);

或者，如果要对特定的MasterPage控制执行该方法:

Or, if you want to perform the method on a specific MasterPage contorl:

DisableControls(this.Page.Master.FindControl("Panel1"), isEnable);

更新:

为什么不将方法放在母版页上?

Why don't you just put a method on your MasterPage:

public void SetControlEnabledState(bool enabled)
{
   DisableControls(Menu1, enabled);
   DisableControls(Control2, enabled);
}

然后，要访问它，只需在使用母版页的任何页上进行以下操作:

Then, to access it, just do the following from any page that uses the master page:

((MasterPageName)this.Page.Master).SetControlEnabledState(enabled);
