Creating a parent and child treeview checkbox nodes

[mrtukker]

I need to create a treeview control with checkboxes. However, my treeview needs to have checkboxes for the parent and the child. The business logic in my situation is that the user may choose "MS Office" but may not want "Microsoft". I came across asp.net TreeView: how to use CheckBox in TreeView which helps, however, I can't seem to create a checkbox for "Microsoft" & "Adobe" nodes. How would I go about doing that?The html code is: <form id="form1" runat="server"> <div> <h2 style="color:Green">TreeView: ShowCheckBoxes</h2> <asp:Label ID="Label1" runat="server" Text="Checked Favorite" Font-Size="Medium" ForeColor="SeaGreen" Font-Italic="true" > </asp:Label> <br /><br /> <asp:TreeView ID="TreeView1" runat="server" DataSourceID="XmlDataSource1" > <DataBindings> <asp:TreeNodeBinding DataMember="Products" Text="Products" /> <asp:TreeNodeBinding DataMember="Type" TextField="Name" /> <asp:TreeNodeBinding DataMember="Product" TextField="Name" ValueField="ID" /> </DataBindings> </asp:TreeView> <br /> <asp:XmlDataSource ID="XmlDataSource1" runat="server" > <Data> <Products> <Type Name="Microsoft"> <Product ID="1" Name="MS Office"/> <Product ID="2" Name="ASP.NET"/> </Type> <Type Name="Adobe"> <Product ID="1" Name="ColdFusion"/> <Product ID="2" Name="Flex"/> <Product ID="2" Name="Photoshop"/> </Type> </Products> </Data> </asp:XmlDataSource> <asp:Button ID="Button1" runat="server" Text="Submit Favorite" OnClick="Button1_Click" /> </div> </form> The code behind is: using System;using System.Collections;using System.Configuration;using System.Data;using System.Linq;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.HtmlControls;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Xml.Linq;namespace TreeviewCheckboxSample{ public partial class Treeview : System.Web.UI.Page { protected void Button1_Click(object sender, EventArgs e) { Label1.Text = "Your favorite:"; if (TreeView1.CheckedNodes.Count > 0) { foreach (TreeNode node in TreeView1.CheckedNodes) { Label1.Text += "<br />" + node.Text.ToString(); } } else { Label1.Text = "Checked before submit."; } } protected void Page_Load(object sender, EventArgs e) { if (!this.IsPostBack) { TreeView1.ShowCheckBoxes = TreeNodeTypes.Leaf; TreeView1.ForeColor = System.Drawing.Color.Black; TreeView1.BackColor = System.Drawing.Color.White; TreeView1.Width = 200; Button1.Font.Bold = true; Button1.ForeColor = System.Drawing.Color.Crimson; } } }}
