我正在尝试创建具有多个子项的Parent的轨道,并将主题置于动态ListBox
中我有这个ParentActivity表“
我希望将依赖于ParentActivity表的曲目放在ListBox中,如下所示:
到目前为止的代码:
-1
例如ParentActivityID = 1;
selectBrotherActivity是查询以获取其父子的另一个孩子
它给了我这样的发行:
| 1 | 2 3 | 4 5 | 7 | 9 | 10 | 7 | 9 | 10 | 6 | 8 | 9 | 10 |
哪个||表示ListBox
答案 0 :(得分:0)
好的,感谢我找到的每个人:
protected void btnCreateTrack_Click(object sender, EventArgs e)
{
ListBox lstBoxParent = new ListBox();
lstBoxParent.ID = "lstTrack1";
lstBoxParent.Width = 200;
lstBoxParent.Height = 200;
pnlTrack.Controls.Add(lstBoxParent);
TrackingActivity(1, lstBoxParent );
}
private void TrackingActivity(long ParentActivityID, ListBox lstBoxParent)
{
chk:
DataTable dtActiveChild = objWFAI.SelectActivityChild(ParentActivityID);
string ActivityName = objWFA.CurrentActivityName(ParentActivityID);
lstBoxParent.Items.Add(new ListItem(ActivityName, ParentActivityID.ToString()));
for (int i = dtActiveChild .Rows.Count - 1; i >= 0; i--)
{
long ActivityChildID = Convert.ToInt64(dtActiveChild .Rows[i][" ActivityID"].ToString());
if (i != 0)
{
ListBox lstBoxChild = new ListBox();
lstBoxChild.ID = "lstTrack" + ActivityChildID.ToString();
lstBoxChild.Width = 200;
lstBoxChild.Height = 200;
pnlTrack.Controls.Add(lstBoxChild);
for (int p = 0; p < lstBoxParent.Items.Count; p++)
{
lstBoxChild.Items.Add(new ListItem(lstBoxParent.Items[p].Text, lstBoxParent.Items[p].Value));
}
TrackingActivity(ActivityChildID, lstBoxChild);
}
else
{
ParentActivityID = ActivityChildID ;
goto chk;
}
}
