當鼠標點擊treeview子元素時保持背景色

Question

如何在ASP.NET TreeView中點擊任何一個子元素時保持背景色？

Answer 1

使用treenodedatabound事件樹視圖，並添加每個項目onclick事件調用javascript函數做任何你想做

protected void TreeView1_TreeNodeDataBound(object sender, TreeNodeEventArgs e) 
     { 
      e.Node.Text = "<span onclick='javascript:MyFunction(this);'>Text</span>"; 
     } 

，或者你可以用這種方式

Dim deletenode As New TreeNode("<span onclick=""javascript:confirm('Are you sure you want to delete this ?');"">Delete</span>", "0" & dr("ProjectID"))

Js功能樣本

MyFunction(sender) { 
//using jquery you have the html element (td) you can get any value from that element based on your senario 
//for example you have attribute called x holding the value you want 
alert($(sender).attr("x")); 

//or to change the background color 
$(sender).css("background-color" , "blue"); 

}
