Hi,

We are using the version 2011.2.712.40 of telerik.
I want to prevent the postback of a radtoolbar with an OnClientButtonClicked to open a RadWindow.
I use e.set_cancel(true); but i receive always a javascript error : Error: Object doesn't support property or method 'set_cancel'

Any idee what is this probleem ?

In advance thanks.

Edwin.

[Solved] RadEditor doesn't show hidden fields in designe mode.

Hi guys!
First of all to clarify that I am using Telerik.Web.UI v. 2011.1.413.40, so it may be addressed already in the newer versions. I am doing some Sitefinity development, that's why I am using that version of the controls.
The problem is that hidden fields are really hidden ;) in the editor when used under IE 9, while they show up in IE versions lower than 9 and are selectable in the Editor design view. Not really a big deal, can you tell me if this is addressed and the hidden fields are shown in some of the newer versions of the editor under IE 9 or not?

If they are I'll not bother to search for workaround (my release will probably fall after the Q3 release so I think I'll be using pretty new version of the controls if Sitefinity include it).

Refer to the screenshots for examples.
I am starting off with a blank HTML with only

<input type="hidden" value="test"></input>

In IE 9 as you can see the editor design surfice is blank, while the hidden field is correctly displayed and selectable in lower versions.
Once again it is not a big deal and once again - I just want to know if this is addressed or will be addressed (seems very low priority but it may appear important to my project).

[Solved] RadGrid Double Click with Single Click

I have a requirement to fire a client side event on Telerik RadGrid Row Double Click, and an update fetching from server on single click. But Double click event doesn't work. If I remove "EnablePostBackOnRowClick" option, then it works fine. How can I use both? Here is my code

<ClientSettings AllowGroupExpandCollapse="True" ReorderColumnsOnClient="false" AllowDragToGroup="false"
      AllowColumnsReorder="false" EnablePostBackOnRowClick="true" >
      <ClientEvents OnRowDblClick="RowDblClick" />                  
  </ClientSettings>

LinkManager and title texts

Hi!

I know how to add my own localized texts for editor's toolbar in the code-behind, but how do I do it for LinkManager dialogbox? I'd like to use my own database and custom ResourceProviderFactory.

Example how I do it for toolbar:

Dim editor As New Telerik.Web.UI.RadEditor

editor.EditModes = EditModes.Design

Dim toolGroup As New Telerik.Web.UI.EditorToolGroup

editor.Tools.Add(toolGroup)

Dim bold As New Telerik.Web.UI.EditorTool

bold.Name = "Bold"

bold.Text = HttpContext.GetGlobalResourceObject("Global", "editorBold")

toolGroup.Tools.Add(bold)

Method failed in usercontrol

Hi,
I implemented a treeview using webservice in a web page and it worked ok. the treeview is simple as follows:



<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="CategoryTreeView.aspx.cs" Inherits="iBOOKSTORE.CategoryTreeView" %>
 
<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <div>
   
 
                <telerik:RadTreeView ID="tvClass" runat="server" Height="400px" Width="500px"
                      Skin="Windows7" CheckBoxes="True" CheckChildNodes="True">
                    <WebServiceSettings Path="CategoryTreeView.aspx" Method="GetClassItems" />
                </telerik:RadTreeView>
     
    </div>
    </form>
</body>
</html>

the webmethod "GetClassItems" worked fine.
but when I convert it into a usercontrol like the following:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="UserTreeView.ascx.cs" Inherits="iBOOKSTORE.UserTreeView" %>

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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<div>

<telerik:RadTreeView ID="tvClass" runat="server" Height="400px" Width="500px"

Skin="Windows7" CheckBoxes="True" CheckChildNodes="True">

<WebServiceSettings Path="UserTreeView.ascx" Method="GetClassItems" />

</telerik:RadTreeView>

</div>

there is no difference between server side Methods. And I drag this usercontrol "UserTreeView.ascx" and drop it on a web page at the same directory. The treeview loaded ok by calling a server side function which returned a datatable. but when I click open a node, an error message popped up "GetClassItems Failed". I tried to set a break point in the WebMethod "GetClassItems", the execution never got inside. I suppose this must have something to do with the Path property. I purposely place the host page and usercontrol in the same directory, but no matter what I tried the same error occured. could you provide some advice please.
Thank you.
I send the server side code as well

Databinding methods such as Eval() ... etc ... error after postback from combobox in grid.

I have a hierarchical grid with a nestedview template in one of the child grids. A couple of the grids have a cascading combo, where one combo triggers a postback so that the second combo can be populated with new data. The problem I have is that I'm getting a

"Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."

error when the selected item of the first combo is changed.

I've looked around but haven't found the solution yet. I've had this issue before but can't remember how I solved it (or even if I did). I'm wondering in this instance if it's a RadGrid-specific issue. One option will be to handle the postback and repopulation (I'm assuming that it's the combos that are causing the problem) programmatically but I'm not sure how to do that when the combos are in an editform or in a grid contained in a nestedview template.

I have this editor on a page:

<telerik:RadEditor ID="editorPageContent" runat="server" EditModes=

What is appears to have done is stripped out all the double quotes (") from all the class properties, which when I then insert the content into a web page causes the page not to work...

Any ideas?
