在treeview asp.net中使用复选框 [英] Working with checkbox in treeview asp.net

问题描述

我想知道如何编程复选框检查里面的树视图，我想编写代码，当用户检查复选框在asp.net中的treeview，我得到的事件称为TreeNodeCheckChange事件，我写了一个response.write（）消息里面，但当我检查复选框，没有什么发生，asp.net treeview支持处理从代码后面的复选框。

i want to know how to program the checkbox checked inside treeview, i want to write code when user checks checkbox inside the treeview in asp.net, i got the event known as TreeNodeCheckChange event, i wrote a response.write() message inside it, but when i check the checkbox, nothing happens, does the asp.net treeview supports handling the checkbox from code behind.

提前感谢。 >

Thanks in advance.

推荐答案

尝试在TreeNode元素上设置 SelectAction =Select

Try setting SelectAction="Select" on the TreeNode element.

<asp:TreeView ID="TreeView1" runat="server" OnTreeNodeCheckChanged="TreeView1_TreeNodeCheckChanged">
    <Nodes>
        <asp:TreeNode ShowCheckBox="true" SelectAction="Select" />
    </Nodes>
</asp:TreeView>
