如何将列表视图中的选定行显示到文本框？
This is how I do int dataGridView:
这就是我如何做 int dataGridView：
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();
}
}
I tried this:
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;
}
}

You may want to check if there is a SelectedItem first. When the selection changed, ListViewwould actually unselect the old item then select the new item, hence triggering listView1_SelectedIndexChangedtwice. Other than that, your code should work:
您可能想先检查是否有 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;
}
}

// select row listview check in c#
// 在 C# 中选择行列表视图检查
foreach (ListViewItem itemRow in taskShowListView.Items) {
foreach（taskShowListView.Items 中的 ListViewItem itemRow）{
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();
}
}
