单击我的值并按下我的 OK_button 后，我无法从 listView 中获取值以将其保存在其他地方。我不能使用 listView1.FindItemWithText 因为我没有要搜索的文本.. Idk 如何在按下 OK_button 后查找单击的值
//Create dummy data to display
myData = new string[dataListSize];
for (int i = 0; i < dataListSize; i++)
{
myData[i] = String.Format("{0}", i);
}
}
private void listView1_SearchForVirtualItem(object sender, SearchForVirtualItemEventArgs e)
{
e.Index = Array.FindIndex(myData, s => s == textBox1.Text.ToString());
}
private void listView1_RetrieveVirtualItem(object sender, RetrieveVirtualItemEventArgs e)
{
e.Item = new ListViewItem(myData[e.ItemIndex]);
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
String MyString = textBox1.Text.ToString();
ListViewItem lvi = listView1.FindItemWithText(MyString.TrimEnd());
//Select the item found and scroll it into view.
if (lvi != null)
{
listView1.SelectedIndices.Clear();
listView1.SelectedIndices.Add(lvi.Index);
listView1.EnsureVisible(lvi.Index);
}
}
private void listView1_SelectedIndexChanged(object sender, EventArgs e){ }
private void OK_button_Click(object sender, EventArgs e)
{
try
{
// OK -> Daten übernehmen
int iCount = this.listView1.SelectedIndices.Count;
if (iCount != 1)
{
MessageBox.Show("Value is empty");
return;
}
DialogResult = DialogResult.OK;
Close();
}
catch (Exception)
{
//WriteProtokoll(ex.ToString(), 0);
Close();
}
}
