查找名称WPF控件 [英] Find WPF control by Name

问题描述

我经过一些帮助寻找指已经programmtically建在C＃控制的最好办法

I'm after some help finding the best way to refer to controls that have been programmtically built in C#

如果我预先包括XAML并将其命名标签 marketInfo 然后在代码中，我可以设置标签属性的东西，如

If I pre include a label in XAML and name it marketInfo then in code I can set the Tag property with something like

marketInfo.Tag = timeNow;

不过，我楼宇控制，并使用类似的东西。

However, I'm building controls and assigning each a name using something similar to

System.Windows.Controls.Label lbl = new System.Windows.Controls.Label();
lbl.Content = market.name + " - " + DateTime.Now.ToLocalTime().ToLongTimeString();
lbl.HorizontalContentAlignment = System.Windows.HorizontalAlignment.Left;
lbl.Height = 40;
lbl.Name = @"_" + "marketInfo" + countMarket;

我如何把这些控件从另一个方法是什么？我阅读过的建议使用 visualtreehelper 但这似乎需要循环控制，以找到一个特定的控制几个职位。类似是否有访问由名称的控制，以避免循环的方法？

How do I refer to these controls from another method? I've read a few posts which suggest using the visualtreehelper but this appears to require looping controls to find a particular control. Is there a way to access a control by name to avoid looping?

如东西

//pseudo code
SomeControl("_marketInfo5").Tag = timeNow;

感谢您

推荐答案

有至少两种方法可以做到这一点：

There's at least two ways to do that:

• 使用 FindName 父容器的方法寻找控制：的 http://msdn.microsoft.com/en-us/library/system.windows.frameworkelement.findname（v = vs.110）的.aspx （但它会在内部循环涉及，像visualtreehelper）

• Use the FindName method of the parent container to find the control: http://msdn.microsoft.com/en-us/library/system.windows.frameworkelement.findname(v=vs.110).aspx (but it'll internally involve looping, like the visualtreehelper)

创建一个字典来存储你创建的每个控件的引用

Create a dictionary to store a reference for each control you create

var controls = new Dictionary<string, FrameworkElement>();
controls.Add("_marketInfo5", lbl);

然后，你可以这样做：

Then you can do:

controls["_marketInfo5"].Tag = timeNow;
