将控件的内容传递给另一个表单 [英] pass contents of a control to another form

问题描述

我正在尝试将数据从当前表单传递到第二个表单以保存第二次输入数据。以下是我要做的事情：

I am trying to pass data from current form to a second form to save entering the data a second time. Here is what I am trying to do:

Inventory_Info_Form inventory_Info_Form = new Inventory_Info_Form();
inventory_Info_Form.part_NumberComboBox.Text= part_NumberComboBox.Text;
inventory_Info_Form.part_DescriptionTextBox.Text = part_DescriptionTextBox.Text;
while (inventory_Info_Form.ShowDialog() != DialogResult.OK)
{
}

带下划线的控件给出了以下错误：

inventory_Info_Form.part_NumberComboBox由于其保护级别而无法访问，而下一行的粗略级别相同。



我在另一个类中有相同类型的代码行但是无法弄清楚它在其他类中的工作原理而不是在这个类中。



任何想法？谢谢

the underlined controls are giving me the following error:
inventory_Info_Form.part_NumberComboBox is inaccessible due to its protection level and the same of coarse for the next line.

I have this same type line of code in another class but can't figure out why it works in the other class and not in this one.

any ideas? Thanks

Use parametrized constructor to send data from one from to another .You can use code as follows (Sending form)

Inventory_Info_Form inventory_Info_Form = new Inventory_Info_Form(part_NumberComboBox.Text,part_DescriptionTextBox.Text);
while (inventory_Info_Form.ShowDialog() != DialogResult.OK)
{
}

So you need to define a parametrized constructor for the form named  Inventory_Info_Form . To do you know you can define a parametrized like bellow(Receiving form) 

public Inventory_Info_Form(string combotext,string descriptionText)
{
inventory_Info_Form.part_NumberComboBox.Text= combotext;
inventory_Info_Form.part_DescriptionTextBox.Text = descriptionText;
}

Hope it works! Happy Coding :)
