I have a set of RadDocks with the handle set to none and using a custom handle. When one of these docks is dropped into an empty RadDockZone there is no dotted line shown for the Drop Zone.

I noticed this behavior on your online examples as well:

http://demos.telerik.com/aspnet-ajax/dock/examples/setdraghandleclientside/defaultcs.aspx

to reproduce, empty a dock zone and then drag a RadDock into the emptied zone, you will notice that no indication of the drop zone is visible.

Is there a way to force the dotted border for the drop zone to show while dragging on top of the zone?

Thank you.

RadEditor inside updatepanel and Wizard - error at first time

Hello,

The following bug occurs only in the first time ever you enter the rad editor. In order to reproduce it, you need to clear the internet temporary files in the browser and then enter the page.

The bug is simple: Create a wizard. Put the editor in the second step of a wizard and put the wizard inside UpdatePanel. When you click next to move from the first step to the second step (where the editor is), the editor width becomes huge and the tool buttons are spread all over it.
If you try do it again without clearing the temporary files cache, the editor is fine.

Any ideas to solve it will be appreciated (I'm using 2010 SP1).

The code:

<%@ Page Language="VB" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

<script runat="server">

</script>

<html xmlns="http://www.w3.org/1999/xhtml">

<head id="Head1" runat="server">

</head>

<body>

<form id="form1" runat="server">

<asp:UpdatePanel runat="server">

RadEditor toolbar size

We are using Telerik for ASP.Net Ajax Q1 2008.

I have the following code:

<telerik:RadEditor ID="RadEditorIncompleteComment" runat="server" Width="550px" Height="200px" EditModes="Design" Skin="Outlook" ToolbarMode="ShowOnFocus" EnableResize="False">

<Tools>

<telerik:EditorToolGroup>

<telerik:EditorTool Name="Bold" />

<telerik:EditorTool Name="Italic" />

<telerik:EditorTool Name="Underline" />

<telerik:EditorTool Name="AjaxSpellCheck" />

</telerik:EditorToolGroup>

</Tools>

</telerik:RadEditor>

When the page is loaded and I click in the RadEditor editing space the toolbar does pop up but it comes up with a minimal width and looks like a thick line. All the tools are hidden. I can drag the right boundary of this thick line and make the tools visible but that's not user-friendly.

Strangely, the first time I used the Rad Editor, a few days ago, it and its toolbar worked perfectly but I found that recommended script for making the Editor look like a textbox was throwing off other code on this page so I unchecked it all out and rebuilt the Rad Editor, resulting in the toolbar issue described above. Does the script control the appearance of the toolbar?

My version of the Rad Editor control does not appear to have a property for controlling toolbar size.

Anyone have any thoughts on this or a recommendation? Thanking you in advance...

[Solved] RadNumericTextBox Parser Error Message: Cannot create an object of type 'System.Type' from its string representation 'System.Decimal' for the 'DataType' property.

Hello

With the latest internal build my Windows 2008 Server Machine is displaying following error. Surprisingly the error does not show on my development machine Windows 7 with VS 2010 Pro Beta 2. This error did not show up with the internal build before the latest one, it did show up with the 2010 Q1 though. I am not sure what is going on here. I did not want to downgrade to previous internal build because that causes RadCombo to have 2 drop down arrows instead of one as I noticed on one other forum posting as well. Which has been fixed in this build.

Here is an overall view.

2010-1-309 Both Server and Development Machines Show Error, RadCombo has 2 drop down arrows problem
2010-1-316 No error on either machine, RadCombo has 2 drop down arrows problem
2010-1-325 Error on Server but not on Development Machine, RadCombo problem fixed

Any insight would be greatly appreciated.

Thanks
Imran

[Solved] Conflict with jQuery-style ASP.Net Form Validators

Hello telerik team.

In some of our projects, we implement the extension from DelphicSage featured on this blog: http://www.delphicsage.com/home/blog.aspx?d=545 to enhance the aesthetics and usability of our websites. However, on one project we have used the Catcha control and noticed that it causes some sort of "conflict" with the extension and hinders it from running properly.

What could be done about this? Thanks much.

Server Side Re-Order

I have a Tree View that controls a Left Navigation which is bound to a database. My database table has the following columns...

NodeID
NodeTxt
NodeURL
NodeVal
NodeParentID
NodeOrder

I added the NodeOrder column because I'm trying to figure how to allow drag/drop reordering of nodes and save the position of the nodes server-side in the database. I've looked at the example in the demos and it shows how to achieve this client side...event though I don't believe the positions are actually stored to a database or anything.

Do you have any examples of how this can be implemented server side so that the ordering of the nodes can be set and retrieved from a database when dragging and dropping child nodes?

Thanks =)

Problem with radalert

I'm trying to build an alert into my master page that can be accessed from anywhere in the UI code-behind. Any method, any function.

I was doing quite well (I think) but I'm stuck now.

Master page

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Default.Master.cs" Inherits="Web.App_Templates.Default.Default" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

<asp:ContentPlaceHolder

</asp:UpdatePanel>

</form>

</body>

</html>

Master page code behind

namespace Web.App_Templates.Default

{

using System;

public partial class Default : System.Web.UI.MasterPage

{

public void ShowFeedback(string feedBackText, bool useAlert)

{

if (useAlert)

{

string radalertscript = string.Format(

"<script language='javascript'>function f(){{radalert('{0}', 330, 210);Sys.Application.remove_load(f);}};Sys.Application.add_load(f);</script>"

, feedBackText);

Page.ClientScript.RegisterStartupScript(this.GetType(), "radalert", radalertscript);

}

else

{

this.Feedback.Text = feedBackText;

}

Web content page

<%@ Page Title="Welcome" Language="C#" MasterPageFile="~/App_Templates/Default/Default.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Web.Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<%@ MasterType VirtualPath="~/App_Templates/Default/Default.Master" %>

<asp:Content ID="MainContent" ContentPlaceHolderID="MainContentPlaceHolder" runat="server">

<asp:Button

ID="TestFeedbackAlert"

runat="server"

-

<asp:Button

ID="TestFeedbackNoAlert"

runat="server"

Text="Click Me"

OnClick="TestFeedbackNoAlert_Click"

Width="100" />

</asp:Content>

And the code behind

namespace Web

{

using System;

using System.Web.UI;

public partial class Default : Page

{

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

//this.Master.ShowFeedback("<p>Hello, AppWorld!</p>", true);

}

protected void TestFeedbackAlert_Click(object sender, EventArgs e)

{

this.Master.ShowFeedback("<p>Clicked!</p>", true);

}

protected void TestFeedbackNoAlert_Click(object sender, EventArgs e)

{

this.Master.ShowFeedback("<p>Clicked!</p>", false);

}

The alert will show if you uncomment out the entry in the page load. It will also work if you click the TestFeedbackNoAlert button.

It will not work if you click the TestFeedbackAlert button.

I've looked at the suggestions at:
http://www.telerik.com/support/kb/aspnet-ajax/window/calling-radalert-from-codebehind.aspx

But I'm none the wiser. Can anyone help? I need it to work no matter where it gets called (page load, postback, ajax call, etc.)

Regards,
Richard

[Solved] Node Security

I have a scenario I'd like to know if you can help me with...

I want to populate a TreeView using a Linq data source. This is because there is going to be another page that graphically allows admins to add/edit/delete/re-order nodes. When the admins work with this page, they will obviously be able to see all the nodes.

Now on the actual page that the TreeView is going to be available to the general public, I want to be able to programatically limit which nodes are visible to the user based on active directory groups. Is there a way to turn nodes visible/hidden after the dataset has been returned from the Linq query? How would I accomplish this?

Thanks for the assistance!

"Google suggest" style filtering

Hi all!

I find two links

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/filteringcombo/defaultcs.aspx

http://www.telerik.com/support/kb/aspnet-ajax/grid/google-suggest-style-filtering-in-radgrid.aspx
(sorry! The Hyperlink Manager's problem so I pasted as the text)

They show the way to use the Radcombobox as the filter of RadGrid, the same way with "Google suggest" now
It's one of the best wonderful support from RadCombobox, a good helpful tool for filtering.
But it's so slow when the RadCombobox has lots of data such as 4,000. Is there any ways to improve this one?

Thanks!

Andy.
