问题描述

我有两种形式.第一个有一个文本框.第二个有一个 devexpress 数据网格.我想实现这一目标:首先单击一个按钮并打开 form2.如果我在 form2 中单击数据网格中的一行，则该值应显示在 form1 中的文本框中.(form1 已打开.)我是初学者.感谢您的帮助.

I have two forms. First one has one textbox.Second one has a devexpress data grid. I want to achieve that: first click a button and form2 opens. if I click a row in the data grid in form2, this value should be shown inside the textbox in form1.(form1 is already opened.) ı m a beginner. thanks for your help.

Form1 frm1 = new Form1();
frm1.textBox1.Text = gridView1.GetFocusedRowCellValue("ID").ToString();
frm1.Show(); 

当我这样做时，会打开一个新表单.我不想打开一个新表格.Form1 已经打开.我想向其文本框添加值.

when I do that, a new form opens. I dont want to open a new form. Form1 is already opened. I want to add values to its textbox.
