Is there a way we can decouple Telerik from integrating from Visual Studio 2010?

Dear Telerik Team,

This is an offshoot of this discussion (http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/how-to-disable-the-rad-update-prompt-in-visual-studio.aspx)

Is there a way we can decouple Telerik from integrating from Visual Studio 2010?

Thanks and Regards,

Can we "freeze" the context sub-menu?

Hello!

I have a question:

Can we configure multi-level context menu on a RadTreeeView to behave the following way:

if user clicks on the selected item, which leads to another sub-menu, this sub-menu becomes visible and stays this way (usually all menus disappear when the user takes cursor off them).

Thank you,

Irene Troupansky

asp:panel navigation inside radwindow - flicker problem

Hi

I am using Radwindow as a modal popup for inline form editing. I have created a wizard, using standard 'asp:panels', inside the ContentTemplate of the Radwindow to break up the form in to smaller chunks. In each asp:panel there is a 'next' and 'back' button which is used to navigate between them. These buttons control server side functions to show/hide the various panels during navigation, and perform some form validation etc. in the background. I need this server side functionality.

The Radwindow is initially hidden on page load, but the 'ButtonAddNew' button is clicked to show it, ready to add a new item.

The problem is that during navigation between panels the page flickers badly in Chrome, Opera and IE (not in Firefox) - I guess it is posting back on the navigation button click. The panels always appear in the end, but the flicker is annoying as a user experience. I have tried putting a RadAjaxPanel around the RadWindowManager to try and stop the flicker - and get a smooth navigation - but this is not working.

Any help would be much appreciated. I have summarised some of the main code below. The Telerik controls are Q3 2010 and it's ASP.NET 3.5.

Thanks in advance.

Kevin

=====================================================
Note: the Radwindow is in a usercontrol. In the Master page there is a standard ScriptManager - I'm using this as there are also some 'ASP.NET Control Toolkit' controls on some of the pages:

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

User control with Radwindow wizard:

<%@ Control language="VB" AutoEventWireup="false" CodeFile="gallery.ascx.vb" Inherits="Gallery" %>

<%@ Reference VirtualPath="~/sites_admin/admin.master" %>

<asp:Button ID="ButtonAddNew" runat="server" CausesValidation="false" OnClick="ButtonAddNew_Click" />

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

<telerik:RadWindowManager ID="RadWindowManager01" Modal="true" runat="server">

<Windows>

<telerik:RadWindow ID="RadWindowImageEdit"

Skin="kSitefinity"

AutoSize="true"

EnableEmbeddedSkins="false"

EnableEmbeddedBasestylesheet="false"

Behaviors= "Close"

VisibleTitlebar="true"

VisibleStatusbar="false"

KeepInScreenBounds="true"

EnableShadow="false"

VisibleOnPageLoad = "False"

runat="server">

<ContentTemplate>

<div style="width: 900px; padding: 6px;">

<asp:panel id="panel01" runat="server">

<asp:button id="ButtonNext01" ValidationGroup="vgText" CausesValidation="True" runat="server"

OnClick="OnClick_ButtonNext01"/>

</asp:panel>

<asp:panel id="panel02" runat="server">

<asp:button id="Buttonback02" ValidationGroup="vgText" CausesValidation="True" runat="server"

OnClick="OnClick_Buttonback02"/>

</asp:panel>

</div>

</ContentTemplate>

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

</telerik:RadAjaxPanel>

CODE BEHIND:

'this pops up the window the first time ready to add a new item

Protected Sub ButtonAddNew_Click(ByVal sender As Object, ByVal e As EventArgs)

'some server side code here

'show the modal popup

RadWindowImageEdit.VisibleOnPageLoad = True

End Sub

'panel navigation

Protected Sub OnClick_ButtonNext01(ByVal sender As Object, ByVal e As EventArgs)

'some validation code here

panel02.Visible = True

panel01.Visible = False

End Sub

Protected Sub OnClick_Buttonback02(ByVal sender As Object, ByVal e As EventArgs)

'some validation code here

panel02.Visible = False

panel01.Visible = True

End Sub

Grid Grouping Sum and Count Problem

Hi

<MasterTableView ShowGroupFooter="True" GroupLoadMode="Client" CellSpacing="-1"></MasterTableView>

<ClientSettings AllowDragToGroup="True"></ClientSettings>

<ExportSettings OpenInNewWindow="True" ExportOnlyData="True" FileName="DataExport"></ExportSettings>

</telerik:RadGrid>

Protected Sub RadGrid1_ColumnCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridColumnCreatedEventArgs) Handles RadGrid1.ColumnCreated

If e.Column.DataType.Name = "DateTime" Then

CType(e.Column, Telerik.Web.UI.GridBoundColumn).DataFormatString = "{0:dd/MM/yyyy}"

End If

If e.Column.DataType.Name = "Decimal" Or e.Column.DataType.Name = "Double" Then

CType(e.Column, Telerik.Web.UI.GridBoundColumn).DataFormatString = "{0:N3}"

CType(e.Column, Telerik.Web.UI.GridBoundColumn).Aggregate = Telerik.Web.UI.GridAggregateFunction.Sum

End If

If e.Column.ColumnType = "GridBoundColumn" And counteklendi = False Then

CType(e.Column, Telerik.Web.UI.GridBoundColumn).Aggregate = Telerik.Web.UI.GridAggregateFunction.Count

CType(e.Column, Telerik.Web.UI.GridBoundColumn).FooterText = "Total : "

counteklendi = True

End If

End Sub

Heirarchical Binding

Hi,

I have two columns available for creating a heirarchical treeview:

PositionNumber ReportsTo

10030 10004

10122 10030

10838 10030

10923 10030

11015 10030

11229 10030

11422 10030

11453 10030

When binding, I get the error "These columns don't currently have unique values".

I understand the error. There are two '11015' PositionNumber values. These are two distinct records thast have the same position number... How can I make my treeview use the values as set out above?

Actually, I don't care what the control is just so long as I can view my data heirarchically presented. If another control is more suited, do let me know!

Thanks,
Richard

RadListBoxItemCollection client API issue with forEach when using IE 8

I have the following javascript function for the OnClientTransferred event of a RadListBox. This function works fine with Firefox and Chrome but I get a javascript error with IE 8.
Here is my javascript.

    
                 <telerik:RadCodeBlock ID="RadCodeBlockMain" runat="server"> 
        
            <script type="text/javascript"> 
        
                       function OnClientTransferredHandler(sender, e) { 
        
                           var myitems; 
        
                           var radbox = $find('<%= CurrentlyTransferredValues.ClientId %>'); 
        
                           var radbox2 = $find('<%= SourceListBox.ClientId %>'); 
        
                           myitems = e.get_items(); 
        
                           myitems.forEach(function(item) { radbox.set_value(radbox.get_value() + item.get_value() + ","); }); 
        
                           radbox2.set_value(e.get_sourceListBox().get_id()); 
        
                       } 
        
             </script> 
        
               </telerik:RadCodeBlock>

The error from IE 8 is the following.
"Microsoft Jscript runtime error: Object doesn't support this property or method"
It seems to fail at line with the forEach statement.

Thanks in Advance
