Hi,

I have a treeview control in a webpartzone. How can i personalize the treeview for each user.

thanks

One way you can personalize a treeview control is by overriding the treeview control, expose the properties that you want to be personalizable by users and put that control in the webpartzone.

An example is a simple custom treeview which allows users to personalize the foreground color:

public class PersonalizableTreeView : TreeView {
   [Personalizable]   <-- override this property and mark it personalizable
   public override System.Drawing.Color ForeColor {
      get {
         return base.ForeColor;
      }
      set {
         base.ForeColor = value;
      }
   }
}

Hope this answers your question.
Helen

Hi Helen,

Thanks for the reply.
Actually i want to save the nodes that have been checked or the nodes that have been collapsed or expanded in a tree.
So that when logged in again we have the same view of the tree. Can that be done?

hello.

well, put your treeview inside a webpart control and implement the IPersonalizable interface (hope the name hasn't changed since beta2). the easiest way to do this is to put the tree view inside a user control. here's a quick example that uses a suer control to maintain the value of a radio button:

<%@ Control Language="C#" ClassName="RadioButtonWebPart" %>

<%@ Import Namespace="System.Web.UI.WebControls.WebParts" %>

<%@ Implements

 Interface="System.Web.UI.WebControls.WebParts.IPersonalizable" %>

<script runat="server">

 private bool _isDirty = false;

 public void Load( PersonalizationDictionary dic ) {

   PersonalizationEntry entry = dic["Sex"];

   if( entry != null ) {

    sex.SelectedValue = (string)entry.Value;

   }

 }

 public void Save( PersonalizationDictionary dic ) {

  dic ["Sex"] = new PersonalizationEntry( sex.SelectedValue,

      PersonalizationScope.User );

    }

 public bool IsDirty {

  get{ return _isDirty; }

 }

 void ProcessChanged( object sender, EventArgs args ) {

   _isDirty = true;

 }

</script>

Sexo:

<asp:RadioButtonList runat="server" ID="sex"

   OnSelectedIndexChanged="ProcessChanged">

 <asp:ListItem Text="Masc" Value="M"  />

 <asp:ListItem Text="Fem" Value="F"  />

</asp:RadioButtonList>
