C# winform在子窗体操作父窗体报错

[yangchun1213]

1. 我有一个父窗体，名字是：ICCardManageMent，父窗体有个方法： public void RefeshStuData()在这个方法里面会用到父窗体的一些控件，如： pageIndex = Convert.ToInt32(studentBindingPage.PositionItem.Text);
// studentBindingPage.PositionItem.Text = pageIndex.ToString();
stuTchName = txtStuTchName.Text;
ICCardStatus = this.cmbICCardStatus.SelectedIndex + 1;
并且在父窗体有这么一段代码设置子窗体：GrantStuICCard stuForm = new GrantStuICCard(stuInfo);
stuForm.Owner = this;
2.有一个子窗体，名字为GrantStuICCard

我在子窗体调用父窗体的RefeshStuData方法时，会报异常，在子窗体是这样调用的：
ICCardManageMent parentForm = (ICCardManageMent)this.Owner;
parentForm.RefeshStuData();
this.Close();

异常是：线程间操作无效: 从不是创建控件“cmbICCardStatus”的线程访问它。
请问我要怎么解决呀，求大神指点呀

用事件

//父窗体代码
GrantStuICCard stuForm = new GrantStuICCard(stuInfo);
stuForm.RefeshStuData+=RefeshStuData;
                    stuForm.Owner = this;

//子窗体代码
public delegate void RefeshStuDataHandler();
public event RefeshStuDataHandler RefeshStuData;
//子窗体调用
if(RefeshStuData!=null)
{
RefeshStuData();
}

或者

public void RefeshStuData()
{
studentBindingPage.Invoke(new MethodInvoker( delegate() {  pageIndex = Convert.ToInt32(studentBindingPage.PositionItem.Text); }));
                // studentBindingPage.PositionItem.Text = pageIndex.ToString();
 stuTchName.Invoke(new MethodInvoker( delegate() { stuTchName = txtStuTchName.Text; }));
this.cmbICCardStatus.Invoke(new MethodInvoker( delegate() {  ICCardStatus = this.cmbICCardStatus.SelectedIndex + 1;}));
}
