c# - 将所选行从 ListView 显示到文本框？

Question

如何将listview选中的行显示到textBox中？

这就是我对 int dataGridView 的处理方式:

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;
    }
}

您可能想先检查是否有 SelectedItem。 When the selection changed, ListView would actually unselect the old item then select the new item, hence triggering listView1_SelectedIndexChanged twice.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;
    }
}
