c# - 将列表视图中的选定行显示到文本框？

Question

如何将选定的行从列表视图显示到文本框？

这就是我做 int dataGridView 的方式：

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    dataGridView1.Rows[e.RowIndex].ReadOnly = true;
    if (dataGridView1.SelectedRows.Count != 0)
    {
        DataGridViewRow row = this.dataGridView1.SelectedRows[0];
        EmpIDtextBox.Text = row.Cells["EmpID"].Value.ToString();
        EmpNametextBox.Text = row.Cells["EmpName"].Value.ToString();
    }
}

我试过这个：

private void listView1_SelectedIndexChanged(object sender, EventArgs e)
{
    ListViewItem item = listView1.SelectedItems[0];
    if (item != null)
    {
        EmpIDtextBox.Text = item.SubItems[0].Text;
        EmpNametextBox.Text = item.SubItems[1].Text;
    }
}

Answer 1

您可能需要先检查是否有 SelectedItem。When the selection changed, ListViewwould actually unselect the old item then select the new item, hence triggering listView1_SelectedIndexChangedtwice. 除此之外，您的代码应该可以工作：

private void listView1_SelectedIndexChanged(object sender, EventArgs e)
{
    if (listView1.SelectedItems.Count > 0)
    {
        ListViewItem item = listView1.SelectedItems[0];
        EmpIDtextBox.Text = item.SubItems[0].Text;
        EmpNametextBox.Text = item.SubItems[1].Text;
    }
    else
    {
        EmpIDtextBox.Text = string.Empty;
        EmpNametextBox.Text = string.Empty;
    }
}

// 在 C# 中选择行列表视图检查

foreach (listViewItem itemRow in taskShowListView.Items) {

            if (itemRow.Items[0].Checked == true)
            {

                int taskId = Convert.ToInt32(itemRow.SubItems[0].Text);

                string taskDate = itemRow.SubItems[1].ToString();
                string taskDescription = itemRow.SubItems[2].ToString();



            }


        }
