我已将Fname和ID绑定到checkedListBox。我在checkedListBox中只看到了Frame。我想在checkedListBox(某些Frame)中选择一些项目。

当我按下按钮时 - 我想看到我选择的列表(我选择的ID列表)。

我正在填写checkListBox,如下所示:

 SQL = "select distinct TrapName,substr(TrapNum,1,4) from TrapTbl order by substr(TrapNum,1,4) ";
            adp = new OracleDataAdapter(SQL, Conn);
            dsView = new DataSet();
            adp.Fill(dsView, "TrapTbl");
            adp.Dispose();
            this.ListAtar.DataSource = dsView.Tables[0];
            this.ListAtar.DisplayMember = dsView.Tables[0].Columns[0].ColumnName;
            this.ListAtar.ValueMember = dsView.Tables[0].Columns[1].ColumnName;

我的问题是,当我从checkedListBox中选择一些项目并按下按钮时 - 如何获取ID列表 - ValueMember ??

答案 0 :(得分:1)

您有SelectedItemSelectedItems作为checkedListBox的属性。

来自MSDN的示例:

private void youbutton_Clicked(object sender, System.EventArgs e)
{
   // Get the currently selected item in the ListBox.
   string curItem = listBox1.SelectedItem.ToString();

   // Find the string in ListBox2.
   int index = listBox2.FindString(curItem);
   // If the item was not found in ListBox 2 display a message box, 
   // otherwise select it in ListBox2.
   if(index == -1)
      MessageBox.Show("Item is not available in ListBox2");
   else
      listBox2.SetSelected(index,true);
}

略有修改。
