用字典从子窗体填充组合框 [英] Populating combobox from child form with dictionary

问题描述

美好的一天

我在Windows应用程序中创建了两种形式.在我的主窗体上是一个组合框，在我的第二个(子窗体)上是一个按钮.

当在子窗体上单击按钮时，我想用字典填充组合框.

我已经写了字典，该字典要求一个简短的过程.该词典正在运行，并且正在从主要形式中填充.

这是主窗体上的词典代码

Good day

I have created a two forms in my Windows application. On my Main form is a combobox and on my second(child) form is a button.

I want to populate the combobox with a dictionary when the button is clicked on the child form.

I have written the dictionary that is calling a short procedure. The dictionary is working and is populating from the main form.

Here is the dictionary code on the Main Form

public void dctRplStatus()
       {
                Dictionary<string, int> objdic = new Dictionary<string, int>();
                objdic = clsIngadmin.SelectdicReplacementStatus();
                cmbRplStatus.DisplayMember = "Key";
                cmbRplStatus.ValueMember = "Value";
                cmbRplStatus.DataSource = new BindingSource(objdic, null);
                objdic = null;

按钮单击事件上子窗体上的代码

Code on child form on the button click event

frmMain formmain = new frmMain()

formmain.cmbRplStatus = dctRplStatus;

我收到一个错误，无法将类型"void"转换为"System.Windows.Forms.Combobox"

我将dctRplStatus()方法更改为字符串，并尝试返回objdic，但它不起作用.

我做错了什么?

Thanx

I get an error connot convert type ''void'' to ''System.Windows.Forms.Combobox''

I change my dctRplStatus() method to a string and tried to return the objdic but it did not work.

What am I doing wrong?

Thanx

推荐答案

将dctRplStatus 的方法签名更改为

Change the method signature of dctRplStatus to

public void dctRplStatus(ComboBox cmbRplStatus)

并替换

and replace

formmain.cmbRplStatus = dctRplStatus;

与

with

dctRplStatus(formmain.cmbRplStatus);

确保formmain.cmbRplStatus具有public 访问权限.

ensure that formmain.cmbRplStatus has public access.
