在TabControl中循环控制 [英] Loop through controls in TabControl

问题描述

我正在寻找一种方式来循环控制tabcontrol的特定选项卡上的控件。例如，我有一个tabcontrol与下列标签：

汽车，
宠物，
管理

每个选项卡上有几个控件来显示/编辑/保存数据等。在保存按钮上，我想遍历该特定选项卡的控件，检查是否所有必填字段所以，如果我在汽车选项卡上，然后单击保存，我只想循环通过汽车选项卡上的控件，而不是宠物或管理员标签。

如何才能达到这个结果？

解决方案

为了遍历TabControl的控件，你需要使用Controls属性。

这是一个有关TabControl的MSDN文章。

示例：

  TabPage page = aTabControl.SelectedTab; 
 
 var controls = page.Controls; 
 
 foreach（控件中的var控件）
 {
 //做东西
} 
  

I am looking for a way to loop through controls on a particular tab of a tabcontrol. For example, I have a tabcontrol with the following tabs:

Cars, Pets, Admin

On each of these tabs are several controls to display/edit/save data, etc. On the "Save" button, I would like to loop through the controls for that particular tab to check whether all required fields have been filled in.

So, if I am on the Cars tab and click "Save," I want to loop ONLY through the controls on the Cars tab and NOT the Pets or Admin tabs.

How can achieve this result?

解决方案

As for looping through a TabControl's controls, you need to use the Controls property.

Here's an MSDN article on the TabControl.

Example:

        TabPage page = aTabControl.SelectedTab;

        var controls = page.Controls;

        foreach (var control in controls)
        {
            //do stuff
        }
