Question

我正在使用checklistboxes来显示与表关联的FieldNames（另一个checklistbox）。动态生成多个checklistbox，并在检查其中的任何项时触发事件'OnCheckListBoxItemCheck'。这里检查的当前项目是从对象'sender'获得的。令人怀疑的是，我如何将从动态核对表框中检查的项目与从clbtables检查的项目相关联？请帮忙......

 private void clbTables_ItemCheck(object sender, ItemCheckEventArgs e)
    {

        int indexofselectedtable;
        indexofselectedtable = Convert.ToInt32(clbTables.SelectedIndex);
        Metadata metadataobj = new Metadata(dbProperties);
        List<string> ColumnNames = new List<string>();
        ColumnNames = metadataobj.GetColumns(clbTables.Items[indexofselectedtable].ToString());
        chklistcolumns = new CheckedListBox();

      //Adds to the Checked ListBox
        for (int j = 0; j < ColumnNames.Count; j++)
        {

            chklistcolumns.Items.Add(ColumnNames.ElementAt(j).ToString());
        }

        this.Controls.Add(chklistcolumns);
        //To fire event for a dynamically generated column checklistboxes
        chklistcolumns.ItemCheck += new ItemCheckEventHandler(OnCheckListBoxItemCheck);
    }
 private void OnCheckListBoxItemCheck(object sender, ItemCheckEventArgs args)
    {
            Columns columnobj = new Columns();
            columnobj.ColumnName = this.chklistcolumns.SelectedItem.ToString(); 
            columnobj.TableName = this.clbTables.SelectedItem.ToString();
            selectedColumnsList.Add(columnobj);

    }

这可能是你想要的？

checkedListBox1.Items.Add("test");
checkedListBox1.ItemCheck += new ItemCheckEventHandler(checkedListBox1_ItemCheck);

....

void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
{
    Console.WriteLine(((CheckedListBox)sender).Name + " is the father of item nr: " + e.Index);
    Console.WriteLine("The value of element nr " + e.Index + " is " + ((CheckedListBox)sender).Items[e.Index].ToString());
}

如何链接两个checkedlistbox项目？
