更好地找到ASP.NET控制方式 [英] Better way to find control in ASP.NET

问题描述

我有一个复杂的asp.net的形式，具有一种形式，甚至50到60场像有多视​​点，里面的MultiView我有一个 GridView控件了，里面的GridView我有几个的CheckBox 。

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.

目前我使用的是的FindControl（）方法的链接和检索子ID。

Currently I am using chaining of the FindControl() method and retrieving the child ID.

现在，我的问题是有任何其他方式/解决方案找到ASP.NET中的嵌套控制。

Now, my question is that is there any other way/solution to find the nested control in ASP.NET.

推荐答案

如果你正在寻找一个特定类型的控制，你可以使用一个递归循环像这样的 -

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

下面是我做的，返回给定类型的所有控件的例子

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);
            }
        }
    }
}
