I am using this code as below. When i keep the mouse near the arrow (to scroll over tabs) ,the arrow and the Tab Text overlaps. Its kind of i cant read the tab text.

<telerik:RadTabStrip ID="PSPPreviewRadTabStrip" runat="server" EnableAjaxSkinRendering="true"

EnableViewState="true" EnableEmbeddedScripts="true" ScrollChildren="True" PerTabScrolling="true"

ScrollButtonsPosition="Middle" DataTextField="SectionName" DataValueField="SectionID"

ClickSelectedTab="true" OnTabClick="PSPPreviewRadTabStrip_TabClick" OnClientTabSelecting="OnSelecting">

</telerik:RadTabStrip>

Q1 Controls Problem - Wrong Assembly Added

Hello,

I installed the Q1 2010 controls and I'm having a strange issue. Every time I add a Telerik control on a web form, it creates the necessary assembly code at the top of the form. Like so:

    
            <%@ Register assembly="Telerik.Web.UI, Version=2010.1.216.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" namespace="Telerik.Web.UI" tagprefix="telerik" %>

The only problem is this is the wrong version of the controls I'm using. I'm using the .NET 4.0 controls and the code should actually be this:

    
            <%@ Register assembly="Telerik.Web.UI, Version=2010.1.309.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4" namespace="Telerik.Web.UI" tagprefix="telerik" %>

The difference being the version information. Why would it act like I'm using .NET 3.5 when I am clearly using 4.0 and when the project was created it was created as a 4.0 project? The toolbox even displays the correct controls as being 4.0. For now, I'm going into the code and changing the assembly to correct the version, but ANY time I make a change to a control on the design surface it adds the 3.5 assembly code in addition to my 4.0 assembly code already there. It is slowing me down quite a bit. Can someone help me fix this?

Thanks for any help,
Heath Brown

Creating a new Project causes other to fail

Perhaps someone could explain something very basic to me.

Last week I had a lot of trouble getting an application running after trying an update. After about three days and reading untold postings I managed to get it back to where it was working.

This morning i created a new RadControls VB.NET Webapplication. I opened the default.aspx and am getting the "could not load file or assembly....". So a brand new Radcontrols Web Application does not even work. And on top of that the application that I spent three days getting work again is now not working again.

What the heck is going on!

RadTreeView and Linked Tables

I've been wrestling for a while trying to databind to 2 tables essentially. Custom collections that inherit from IBindingLists, but the core type of collection is not really the problem. I can succesfully bind as long as i only bind one table or collection. Things get tricky when I try to programmatically bind to the next table.

To help understand my problem I am attaching a database diagram of the tables in question.

How can I use databindings to populate data coming from that type of relations, a self-referencing table and a link-table.

I read almost everything available in the forums and online, and found nice text, but no concrete example close to this scenario.

My treeView is not using declarative datasources, I am using the OnDatabinding event to populate the grid:

    
            <telerik:RadTreeView runat="server" ID="RadTreeView1" EnableDragAndDrop="True" OnClientMouseOver="onTreeViewMouseOver" 
        
                    OnClientMouseOut="onTreeViewMouseOut" OnClientContextMenuItemClicking="onClientContextMenuItemClicking" 
        
                    OnClientNodeDragStart="onTreeViewDragStart" OnDataBinding="RadTreeView1_DataBinding" 
        
                    OnClientNodeDropping="onTreeViewDropping" OnClientContextMenuShowing="onClientContextMenuShowing" 
        
                    OnNodeDrop="RadTreeView1_NodeDrop" OnNodeDataBound="RadTreeView1_NodeDataBound"   
        
                    OnClientNodeDragging="onTreeViewDragging" OnNodeEdit="RadTreeView1_NodeEdit"   
        
                    oncontextmenuitemclick="RadTreeView1_ContextClick"   
        
                    AppendDataBoundItems="True">  
        
                    <ContextMenus> 
        
                        <telerik:RadTreeViewContextMenu ID="MainContextMenu" OnDataBinding="MainContextMenu_DataBinding" runat="server">  
        
                            <Items> 
        
                                <telerik:RadMenuItem Value="Rename" Text="Rename ..." Enabled="false" ImageUrl="~/Images/rename.gif" PostBack="false"></telerik:RadMenuItem> 
        
                                <telerik:RadMenuItem Value="NewRootUnit" Text="New ..." ImageUrl="~/Images/newfolder.gif"></telerik:RadMenuItem> 
        
                                <telerik:RadMenuItem Value="Delete" Text="Delete ..." ImageUrl="~/Images/deletefolder.gif"></telerik:RadMenuItem> 
        
                                <telerik:RadMenuItem IsSeparator="true"></telerik:RadMenuItem> 
        
                                <telerik:RadMenuItem Value="SetAsDefault" Text="Set as default ..." ImageUrl="~/Images/default.png"></telerik:RadMenuItem> 
        
                            </Items> 
        
                            <CollapseAnimation Type="InCubic" /> 
        
                        </telerik:RadTreeViewContextMenu> 
        
                    </ContextMenus> 
        
                </telerik:RadTreeView>

And in the NodeDataBound event I actually use custome attributes to hold all the data I need.

My problem comes when i want to hook up the UserInRegion collection of record to the Region Collection.

Thank you in advance,

Jean

Custom Attributes Load on Demand problems

Hello!

I'm populate my RadTreeView via WCF service on demand. In service I'm set custom attribute to RadTreeNode:

                    Attributes = new Dictionary<string, object> { { "TypeAttribute", "Type1" } }         

Next time I'm recieve node with this attribute in WCF service (when I'm expand it), Attributes property contains this keypair: "0, {object}" instead {"TypeAttribute", "Type1"}.

When I'm debug my page in fireBug, I noticed then attributes of node in post json (from page to service) contains value of keypair as string, but response from service contains it as object. Maybe this is a source of problem?

My question is - how I must set custom attributes in WCF service code to correctly get it from "node" parameter of LoadData method of service?

Thank you.

P.S. Sorry for my bad English.

how to make a horizontal chart legend

I know for previous version of RadChart, we can set heightRatio=0
For recent version, there is no heightRatio property for RadChart. I checked the change and compatibility for new versions, Legend.heightRatio is changed to PlotArea].Appearance.Dimensions.Paddings (Left, Right). However, no matter what value I set to PlotArea].Appearance.Dimensions.Paddings, I still got vertical legend.

Any one knows how to do it? Thanks
