[英]How do I access properties from page in ContentPlaceholder in my MasterPage
I have following environment: 我有以下环境:
fooPage
) fooPage
页并实现基类( fooPage
)的多个页面 fooPage
has a certain property ( fooProperty
) fooPage
具有一定的属性( fooProperty
) Now i want to do something like 现在我想做类似的事情
public partial class FooMaster : System.Web.UI.MasterPage
{
// this is originally from the designer-file
protected global::System.Web.UI.WebControls.ContentPlaceHolder ContentPlaceHolder;
protected override void OnPreRender(System.EventArgs e)
{
var fooPageInstance = this.ContentPlaceHolder as fooPage;
var fooPropertyInstance = fooPageInstance.fooProperty;
// TODO do something with the property
}
}
Obviously this is not going to work - but how can I achieve this? 显然这是行不通的-但是我该如何实现呢?
I know the alternative: call a method from the masterPage in the contentPage with fooProperty
as a parameter - but i would like to rather have a pull-system in this case... 我知道另一种选择:使用
fooProperty
作为参数从contentPage中的masterPage调用一个方法-但在这种情况下,我想拥有一个拉式系统...
You can use MasterType
attribute on master page. 您可以在母版页上使用
MasterType
属性。
