自动检查核对表框中的项目 [英] Automatically check items in checklistbox

问题描述

是否有办法在支票清单框中自动检查物品（即12项中的6项）？



目前，我正在尝试编写代码这说明，



当组合框在form1中显示'sweets'时，form2中的checklsitbox会自动检查checklistbox中12个项目中的6个。



我不知道从哪里开始



我尝试了什么：



我已将form1中的组合框设置为公共，不知道从哪里开始

Is there a way have items (i.e. 6 out of 12 items) automatically checked in a checked list box?

Currently, I am trying to write a code which is stating that,

When the combo box says 'sweets' in form1, the checklsitbox in form2 automatically checks 6 out of the 12 items in the checklistbox.

I'm not sure where to start

What I have tried:

I've set the combobox in form1 to public, not sure where to go from there

推荐答案

由于必须检查的组合是第二种形式，最好在Form2中使用一个公共方法来处理逻辑：

Since the combo which has to be checked is in the second form, it would be better to have a public method in Form2 which would handle the logic:

// In form2

public void CheckItems(string param) {
   if (param == "sweets") {
     // Code to check according to your logic
   }
}

您可以从form1调用该方法，提供你在form1中保留了一个有效的实例变量，指向你实际的form2实例。

You could call that method from form1, provided you keep in form1 a valid instance variable pointing to your actual instance of form2.

除了 phil.o [ ^ ]，我建议你阅读：

在两种形式之间转移信息，第1部分：父母对儿童 [ ^ ]

在两种表格之间转移信息，第2部分：从孩子到父母 [ ^ ]

在两种表格之间传递信息，第3部分：儿童与儿童 [ ^ ]

In addition to solution#1 by phil.o[^], i'd suggest to read this:
Transferring information between two forms, Part 1: Parent to Child[^]
Transferring information between two forms, Part 2: Child to Parent[^]
Transferring information between two forms, Part 3: Child to Child[^]
