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 ofdctRplStatus
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.
