如何更新和显示现有的Windows窗体 [英] how to update and show existing Windows Form

问题描述

大家好，

我有两种形式(Form1和Form2).

Form1包含一个DataGridView控件和添加"按钮.
Form2包含文本框和保存按钮.

这是我的跑步表格
1st:单击添加"按钮时将出现Form1
第二个:Form2将出现在此处，将文本添加到文本框中，当我单击保存"按钮时，它已保存到数据库，而Form1仍停留在数据库中.

我的问题是:我想显示现有的Form1，即具有更新数据的Form1，并且不想显示新的Form1.

希望您能理解这个概念.

请帮帮我

Hi all,

I have two forms (Form1 & Form2).

Form1 contains a DataGridView control and Add button.
Form2 contains TextBoxes & save Button.

Here is my running forms
1st: Form1 will appear when click Add button
2nd: Form2 will appear here adding text to text boxes and when I click the save button it''s saved to database and Form1 still stays there.

My question is this: I want to show existing Form ie Form1 with updating data and dont want to show a new Form1.

I hope you understand the concept.

Please help me out

推荐答案

您只需将其用作:

You just need to use it as:

Form1 m_frm = new Form1();
private void button_add_Click(object sender, EventArgs e)
{
    m_frm.Show();
}

在表格1中，您需要处理关闭事件:

and in Form 1 you need to handle the closing event:

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
  e.Cancel = true;
  this.Hide();
}

不要用于From.Show仅使用Form.ShowDialog().

通过访问旧表单属性从旧表单获取所有数据..

您想以新形式执行任何操作.以新形式设置属性
.and
在NewForm Load事件中执行操作.
