禁用用户控件的母版页的负荷 [英] disable usercontrol on the load of master page

问题描述

我使用的某些页面上的母版页。和母版页加载用户的控制。所以我想禁用或启用具有母版页一些页面加载用户控件。

I am using master page on some pages. And that master page is loading the user control. So I want to disable or enable user control on some page load which has master page.

反正我的母版页的Page_Load（）

Is there anyway can I disable User control on master page Page_load()

<div class="ucTabCtrl" >
    <uc1:TLTabControl ID="ctrlname" runat="server" Visible="False" />
</div>

Master Page_load()
{
 // checking some condition if true
 ctrlname.visible = true;
}

但问题是我不能够得到用户CTRL实例，总之ctrlname为空所有的时间。

but the problem is I'm not able to get the instance of user ctrl, in short ctrlname is null all the time.

推荐答案

您的问题是有点难以理解，但我认为你在找什么是这样的：

Your question is kinda hard to understand, but i think what you are looking for is something like this:

public partial class Site1 : System.Web.UI.MasterPage
{
	protected void Page_Load(object sender, EventArgs e)
	{
		if (Page is WebForm1 || Page is WebForm2)
		{
			webUserControl11.Visible = false;
		}
	}
}

另外，您可以实施，表明这种行为的页面的接口。沿着线的东西：

Alternatively you could implement an interface on the pages that indicates this behavior. Something along the lines:

public partial class Site1 : System.Web.UI.MasterPage
{
	protected void Page_Load(object sender, EventArgs e)
	{
		ISpecialPage specialPage = Page as ISpecialPage;

		if (specialPage != null && specialPage.ShouldDisableUserControl)
			webUserControl11.Visible = false;
	}
}

public interface ISpecialPage
{
	bool ShouldDisableUserControl { get; }
}
