有关树视图的问题 [英] issues regarding treeview

问题描述

我正在使用asp.net的树视图控件
有两个问题:

1)使用表格放置树形视图，当我将其展开时，树形视图会下降，如果树形视图增大，我想固定其高度，因此它应在特定的td或区域内增大，并且应该有向下滚动的栏.我需要处理这个问题，否则它会将整个页面向下推，并且我的保存按钮也将下降，因为如果我固定了树视图的区域或td，那么它将在其特定区域中长大，而其余布局仍保留在其上

2)在此层次结构的树形视图中有复选框
大父亲->父亲->孩子
全部带有复选框.
当用户在JavaScript的帮助下单击复选框时，我使用onclick来使用_dopostback来使用检查树视图的更改事件"来执行某些功能.问题是当我们使用...时如何正确使用更新面板...


此函数Onclick onntreeview

there are 2 problems:

1) using table to place tree view and when I expand it the tree view goes down I want to fixed the height if tree view grows so it should grow in specific td or area and there should be scroll bar to go down. I need to handle this else it pushes whole page down and my save button also goes down because of if I fixed the area or td of tree view so it will grow up in its particular region and rest of layout remain on it place

2)There are Check-boxes in tree view in this hierarchy
