如何将listview项目转移到另一个表单？ [英] How do you transfer listview item to another form?

问题描述

借助一些YouTube视频，我能够将数据库中的数据检索并显示到列表视图中。现在我的问题是：



我想点击列表视图中的1行，当我点击编辑/查看按钮时，该行的数据将插入到那些文本框中，组合框等。



基本上，我想选择一行并以另一种形式查看。



我尝试过：

With the help of some youtube videos, I was able to retrieve and display data from the database into the listview. Now my problem is:

I want to click 1 row in the listview and when I click the edit/view button the data from that row would be inserted into those textboxes, comboboxes, etc.

Basically, I want to select a row and view it in another form.

What I have tried:

I used this code to view the data from the database into the listview:

<pre> private void loadtblsupp()
        {
            cn.Open();
            cmd.CommandText = "select * from SupplierTable";
            cmd.Connection = cn;
            dr = cmd.ExecuteReader();
            while (dr.Read())
            {
                ListViewItem item = new ListViewItem(dr["Supp_ID"].ToString());
                item.SubItems.Add(dr["Supp_Name"].ToString());
                item.SubItems.Add(dr["Supp_Address"].ToString());
                item.SubItems.Add(dr["Supp_CPerson"].ToString());
                item.SubItems.Add(dr["Supp_TelNo"].ToString());
                item.SubItems.Add(dr["Supp_FaxNo"].ToString());
                item.SubItems.Add(dr["Supp_Email"].ToString());
                supplier_tb.Items.Add(item);
                
            }
            cn.Close();
        }

推荐答案

具体取决于两种形式之间的关系。

看看这些，其中一个适合你的情况。

创建另一个实例的表格：

Exactly how depends on the "relationship" between the two forms.
Have a look at these, one of them will fit your circumstances.
The form that creates an instance of another:

MyForm mf = new MyForm();
mf.Show();

是父，另一种形式是孩子。

（这并不意味着任何正式的MDI关系）



转让两种表格之间的信息，第1部分：父母与子女 [ ^ ]

在两种表格之间传递信息，第2部分：儿童到父母 [ ^ ]

在两种形式之间传递信息，第3部分：儿童到儿童 [ ^ ]

Is the "parent", the other form is the "child".
(This doesn't imply any formal MDI relationship)

Transferring information between two forms, Part 1: Parent to Child[^]
Transferring information between two forms, Part 2: Child to Parent[^]
Transferring information between two forms, Part 3: Child to Child[^]
