在 ASP.NET 中找到控件的更好方法 [英] Better way to find control in ASP.NET
问题描述
我有一个复杂的 asp.net 表单,在一个表单中甚至有 50 到 60 个字段,就像 Multiview
,在 MultiView 里面我有一个 GridView
,在 GridView 里面我有几个 CheckBoxes
.
I have a complex asp.net form,having even 50 to 60 fields in one form like there is Multiview
, inside MultiView I have a GridView
, and inside GridView I have several CheckBoxes
.
目前我正在使用 FindControl()
方法的链接并检索子 ID.
Currently I am using chaining of the FindControl()
method and retrieving the child ID.
现在,我的问题是有没有其他方法/解决方案可以在 ASP.NET 中找到嵌套控件.
Now, my question is that is there any other way/solution to find the nested control in ASP.NET.
推荐答案
如果您正在寻找特定类型的控件,您可以使用这样的递归循环 -http://weblogs.asp.net/eporter/archive/2007/02/24/asp-net-findcontrol-recursive-with-generics.aspx
If you're looking for a specific type of control you could use a recursive loop like this one - http://weblogs.asp.net/eporter/archive/2007/02/24/asp-net-findcontrol-recursive-with-generics.aspx
这是我制作的一个示例,它返回给定类型的所有控件
Here's an example I made that returns all controls of the given type
/// <summary>
/// Finds all controls of type T stores them in FoundControls
/// </summary>
/// <typeparam name="T"></typeparam>
private class ControlFinder<T> where T : Control
{
private readonly List<T> _foundControls = new List<T>();
public IEnumerable<T> FoundControls
{
get { return _foundControls; }
}
public void FindChildControlsRecursive(Control control)
{
foreach (Control childControl in control.Controls)
{
if (childControl.GetType() == typeof(T))
{
_foundControls.Add((T)childControl);
}
else
{
FindChildControlsRecursive(childControl);
}
}
}
}
