！IsPostBack树视图 [英] !IsPostBack treeview

问题描述

嗨
在加载时使用treeview甚至在绑定treeview时
在那个

 受保护的 无效 HeadCreationTV_Load(对象发​​件人，EventArgs e)
{
    如果(！IsPostBack)
    {
        GetTreeViewBind();

    }
} 

但是在保存按钮中保存了一些值后，我必须再次重新加载树.
我遇到了问题，因为我给了！ispostBack，如果不给我！isPostBack树视图每次都在显示，则向下拖动选定的索引更改等..

有什么解决办法吗?

解决方案

如果您需要在单击按钮后重新加载树，然后在按钮单击处理程序中调用GetTreViewBind.

If you need to reload the tree after the button click then call GetTreViewBind in the button click handler.
