Questions on UI for ASP.NET AJAX Forum

Here is my situation. I have a tree that uses load on demand. The first level is Offices and the second level are Contacts in corresponding offices.
Now, the data source for the offices also returns the number of contacts in the office, which is helpful for this load on demand scenario (the user now knows if the office has nodes in it). However, to display the number in a different color beside the office title, I need to use a template of the Office Nodes. But I want the Contact Nodes below to be regular RadTreeNodes. Now I got it working one way programmatically, but I feel using template on the ASPX side would faster.

Here is my attempt at the ASPX side, which is completely broken and completely wrong, but I'm using it to give you a sense of where I am going.

<telerik:RadTreeView ID="_tvOffice" AutoPostBack="true" Width="100%" Skin="Office2007"

EnableDragAndDropBetweenNodes="true" EnableDragAndDrop="True"

runat="server"

DataFieldID="ID" ContextMenuItemClick="_tvOffice_ContextMenuItemClick" OnNodeExpand="_tvOffice_NodeExpand">

<NodeTemplate>

<telerik:RadTreeNode runat="server">

</telerik:RadTreeNode>

</NodeTemplate>

<Nodes>

<telerik:RadTreeNode EnableContextMenu="false" CssClass="spIcon spFldr_C" AllowDrag="false"

AllowDrop="true" ExpandMode="ServerSideCallBack" runat="server">

<NodeTemplate>

<asp:Label ID="_lblTitle" runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.officeTitle")%>'></asp:Label>

<asp:Label ID="_lblCount" runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.ContactCount", "({0})")%>'

CssClass="lblProjectNum"></asp:Label>

</NodeTemplate>

</telerik:RadTreeNode>

</Nodes>

<DataBindings>

<telerik:RadTreeNodeBinding Depth="0" EnableContextMenu="false" CssClass="spIcon spFldr_C" AllowDrag="false"

AllowDrop="true" ExpandMode="ServerSideCallBack" TextField="officeTitle" ValueField="ID" CategoryField="Category" />

</DataBindings>

</telerik:RadTreeView>

private void RebindOfficeTree(int? companyId)

{

if (companyId == null) return;

var db = new DBStoredProc();

var officeList = db.Offices_OnDemand(companyId);

_tvOffice.DataSource = officeList;

_tvOffice.DataBind();

}

private static void PopulateContactsByOffice(RadTreeNodeEventArgs e)

{

if (e == null || e.Node.Value == null) return;

var db = new DataContext();

var officeId = int.Parse(e.Node.Value);

var contactList = Contacts.LoadByOfficeId(db, officeId);

foreach (var contact in contactList)

{

var node = new RadTreeNode

{

Text = contact.FullName,

Value = contact.Id.ToString(),

CssClass = "spIcon spContact",

Category = "Contact",

AllowDrag = true,

AllowDrop = false

};

e.Node.Nodes.Add(node);

}

e.Node.Expanded = true;

}

Also, I am grabbing the offices by clicking on a Company Node on another tree, but using per-node template, a "blank" tree node appears in the Office tree on page load (before selecting any company).

The point here is speed. I want to use the fastest, most optimized method to do this.

Attributes and WCF Web Service Load On Demand

On the server side, I've built a RadTreeView whose nodes have attributes.

RadTreeView tree = new RadTreeview();

tree.ID = "MyRadTree";

tree.WebServiceSettings.Path = "MyServices.svc";

tree.WebServiceSettings.Method = "GetNodes"

...

RadTreeNode nodes = new RadTreeNode();

...

RadTreeNode expandNode1 = new RadTreeNode();

expandNode1.Text = "Apples";

expandNode1.Value = "1";

expandNode1.Attributes.Add("NodeType", "Fruit");

expandNode1.ExpandNode = TreeNodeExpandNode.WebService;

...

tree.Nodes.AddRange(nodes);

My service, GetNodes(), is called, but the node.Attributes count is 0.

[OperationContract]

public RadTreeNodeData[] GetNodes(RadTreeNodeData node, IDictionary<string, object> context)

{

string value = node.Value; // ok

string text = node.Text; // ok

int attributeCount = node.Attributes.Count; // 0

string attribute = node.Attributes["NodeType"]; // Exception "The given key was not present in the dictionary"

}

Is this supposed to work? Any ideas what I could be missing? Might I need to add a [WebInvoke ...] attribute to my web method, perhaps changing the method style?

(Note that the attribute(s) are available from the client side; they just don't seem to make it through to the web service.)

Thanks.

RadRotator loses animation effect after post back.

Hello,

I use trial version of Web UI Controls & Components for ASP.NET AJAX. I’ve faced a problem with RadRotator animation. I use it in Web User Control. Here is the code for my control FabricItunes.ascx :

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="FabricItunes.ascx.cs" Inherits="test.Controls.FabricItunes" %>

<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>

<style type="text/css">

.rotWrapper

{

margin-left: auto;

margin-right: auto;

height: 260px;

font-family: Arial;

padding: 190px 0 0;

width: 750px;

background: #fff url("travel_back.jpg") no-repeat 0 0;

font: 14px 'Segoe UI' , Arial, Sans-serif;

color: #000;

}

.RemoveRotatorBorder div.rrClipRegion

{

/* The following style removes the border of the rotator that is applied to the items wrapper DIV of the control by default, in case the control renders buttons.

In case you want to removed this border, you can safely use this CSS selector. */

border: 0px none;

}

</style>

</ItemTemplate>

</telerik:RadRotator>

<script type="text/javascript">

reflectionHeight: 0.5, // The height of the reflection

}

); // end of animationOptions

//]]>

</script

The code behid is:

namespace test.Controls

{

public class FabricChoosedEventArgs : EventArgs

{

private string _FabricCode;

public string FabricCode

{

get { return _FabricCode; }

set { _FabricCode = value; }

}

public partial class FabricItunes : System.Web.UI.UserControl

{

public delegate void FabricChoosedEventHandler(object sender, FabricChoosedEventArgs e);

public event FabricChoosedEventHandler OnFabricChoosed;

string virtualPath = "~/Images/Fabrics/";

private void Page_Load(object sender, System.EventArgs e)

{

if (!IsPostBack)

{

FabricColorID = 0;

ConfigureRadRotator(FabricColorID); }

}

public void ConfigureRadRotator(int FabricColorID)

{

RadRotator1.RotatorType = RotatorType.CoverFlow;

RadRotator1.DataSource = GetFilesInFolder(virtualPath, FabricColorID);

RadRotator1.InitialItemIndex = 0;

RadRotator1.DataBind();

}

protected List<string> GetFilesInFolder(string folderVirtualPath, int FabricColorID)

{

testws ws = new testws();

List<string> FL = new List<string>();

FL = ws.FabricsByColor(FabricColorID).ToList();

List<string> virtualPathsCollection = new List<string>();

foreach (String path in FL)

{

string virtualPath = VirtualPathUtility.AppendTrailingSlash(folderVirtualPath) + System.IO.Path.GetFileName(path) + "_th.jpg";

virtualPathsCollection.Add(virtualPath);

}

return virtualPathsCollection;

}

protected void RadRotator1_ItemClick(object sender, RadRotatorEventArgs e)

{

Label lbl = e.Item.FindControl("Label1") as Label;

if (this.OnFabricChoosed != null)

{

FabricChoosedEventArgs r = new FabricChoosedEventArgs();

r.FabricCode = lbl.Text;

this.OnFabricChoosed(this, r);

}

Now when I place this web user control on Web Form Using Master Page it loads perfectly with needed animation effects firs time. But when I click a rotator item it causes page post back and rotator loses all its animation effects.

Here is the code for Web Form:

<%@ Page Title="" Language="C#" MasterPageFile="~/Shop.Master" AutoEventWireup="true" CodeBehind="Shop.aspx.cs" Inherits="test.Shop" %>

<%@ Register src="Controls/BuyItem.ascx" tagname="BuyItem" tagprefix="uc1" %>

<%@ Register src="Controls/FabricItunes.ascx" tagname="FabricItunes" tagprefix="uc2" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder_MainArea" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always">

<ContentTemplate>

<uc3:BuyItem ID="BuyItem1" runat="server" />

</ContentTemplate>

</asp:UpdatePanel>

<div id="pnlProductItunes">

<asp:UpdatePanel runat="server" UpdateMode="Always">

<ContentTemplate>

<div style="height: 155px; margin-top: 35px;">

<uc2:FabricItunes ID="FabricItunes" runat="server" />

</div>

</ContentTemplate>

</asp:UpdatePanel>

</div>

</asp:Content>

The code behid is:

namespace test

{

public partial class Shop : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

this.FabricColors.OnFabricColorChoosed += new test.Controls.FabricColors.FabricColorChoosedEventHandler(FabricColors_OnFabricColorChoosed);

this.FabricItunes.OnFabricChoosed += new test.Controls.FabricItunes.FabricChoosedEventHandler(FabricItunes_OnFabricChoosed);

}

void FabricItunes_OnFabricChoosed(object sender, Controls.FabricChoosedEventArgs e)

{

this.BuyItem1.showFabricImage(e.FabricCode);

}

Please advise how to avoid this animation loosing.
Thanks in advance for any suggestion.

radMenu specific width and wrapped menuItem CSS rmSprite problem

i have a radmenu (skin/black) with a specific width (200px), problem is when a menu item is long and it wraps, the CSS sprite image - since its intended for single line menuItem i think, shows other image included in the sprite image (please see attachment)

now, what i want to happen in when a menuItem wraps and more than one line, the arrow and the background fits perfectly or in the center.

thanks in advance.

Edit: i'm just looking for a quick fix if there's any (i mean not changing the rmSprite entirely) Or back to square one and just custom the whole thing? hehe

Reversing RadSplitter / Image overide

Hello,

I would like to reverse the sliding pane/spillters action.....well part of it. For example I would have a splitter, then a pane then a splitbar then a pane and done.
All this works fine with the split bar between the two panes with both panes visable. The split bar is set to collapse backward. So both panes are visable and when you click on the splitter the splitter moves to the bottom and the bottom pane is hidden.

This is exactly the opposite of what I want. What I would like is when the splitter is (not collapsed) ie between the two panes that the bottom pane be hidden and when the splitter is clicked the splitter draws down revealing the pane contents.

Also the PM would like me to override the default arrow image in the center of the splitter with text "More" and "Less" for the users. So for example when the splitter is at the bottom of the top pane (the top of the bottom pane) it would say More indicating there is more choices if you click. Then when the splitter is at the bottom switch it to say "Less" telling the user they can close up and hide some options.

TIA
JB
