如何在ASP.NET中讓TREEVIEW控件每次展開節(jié)點(diǎn)時(shí)不刷新頁(yè)面
給父節(jié)點(diǎn)設(shè)置屬性:parNode.PopulateOnDemand = true;
后臺(tái)追加兩個(gè)方法:
1.protected void PopulateNode(object sender, TreeNodeEventArgs e)
{
PopulateNode(e.Node);
}
2.private void PopulateNode(TreeNode node)
{
//追加子節(jié)點(diǎn)
}
多重隨機(jī)標(biāo)簽
