TextBox中的树事件 [英] Tree Event In TextBox

问题描述

hii all
我有一棵父母和他们的孩子的树，而不是在文本框中输入孩子的名字，而是想在光标位于文本框中时加载那棵树吗?
因此，我想知道应该处理什么事件来完成该任务，我试图制作(加载)文本框，但是该加载在页面的加载中.
有任何帮助吗?

推荐答案

如果您在页面上进行了一些更改，您可以获得相似的结果，但选择的方式却不完全相同.
当您将鼠标放在TextBox上时，您希望您的Childs Nodes Name出现在TextBox中，但是我尝试了很多，但是在ASP.NET中却无法得到此类事件，但是如果您选择TextBox Load Event并一一单击在Child Node上，则这些子节点将出现(或显示)在文本框中.您只需要在TextBox Load Event中放置以下代码.

受保护的子TextBox1_Load(ByVal发送者作为对象，ByVal e作为System.EventArgs)处理TextBox1.Load

TextBox1.Text + = TreeView1.SelectedValue& " "

结束子

试试这个....

If u make some changes in ur page u can get similar results but not exactly same way u chosed.
U want ur Childs Nodes Name appear in TextBox when u place mouse over TextBox but I tried it so much but can''t get such event in ASP.NET but if u Chose TextBox Load Event & Click on the Child Node one by one then these Child Nodes will appear (or display) in the TextBox. U have to just place following code in TextBox Load Event.

Protected Sub TextBox1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Load

TextBox1.Text += TreeView1.SelectedValue & " "

End Sub

Try this....
