Wow, it's all so freaking HUGE!

I'm sure there is a discussion on this somewhere, but why is it after the Q3 2012 release the font sizing was changed to a size only my grandmother could love? I mean since when is a 16 pt font considered the baseline normal? Now I find myself having to scale my browser to 75% just to get some semblence of usability when viewing the demo site.

[Solved] Toolbox Will Not Drop Controls

As with many other people, I upgraded to your new release this weekend. I have managed to get through most of the issues by reading the forums. However, I have one issue that I haven't seen yet.

I created a new RAD c# website (.aspx) in VS2012. When I have the display file open and try to drag and drop controls on to the page, any Microsoft control that I grab, drag, and drop on to the page work fine. I tried many. No problems.

When I grab any Telerik control (makes no difference which one or from which group), I drop the control on to the page and nothing happens. No control is created.

If I manually create controls (such as copying ones from your demo site and pasting them into the page) the controls work just fine. It's just that no Telerik controls from the Toolbox are created.

Any workarounds available?

[Solved] Rebind Grid in User Control from PopUp

Hi,
I know I have the bad habit to put myself in complicated situations...., but it is not my fault, blame my customers ;-)

The Situation is as follows:
I have a Content Page which has as Master Page. Inside the content Page I load several User Controls. From one of the User Controls, which contains a RadGrid, I open a PopUp to edit the detail of the Grid. The PopUp contains a Button to save the detail and after saving I call a javascript function inside the Content Page (...actually inside the User Control) that triggers a AjaxCall to Rebind the Grid.
Everything works fine....only the first Time !!!
After that the debugger of Firefox tells me that the RadAjax Manager does not exists. I have to reload the Content Page (not even the User Control) to have the Rebind working again.
I'm pasting here some code.

The Master Page has nothing special inside it besides a

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

Beside that only HTML and CSS.

The Content Page:

<%@ Page Title="" Language="VB" MasterPageFile="~/App_Master/SystemSetup/SystemSetup_base.master" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="SystemSetup_Default" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder_Top" Runat="Server">

</telerik:RadToolBar>

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder_Left" Runat="Server">

<asp:button runat="server" ID="B_Eng" Text="ENG" Visible="false" />

<asp:button runat="server" ID="B_Ita" Text="ITA" Visible="false" />

<telerik:RadPanelBar ID="RadPanelBar" Runat="server" Width="100%" AllowCollapseAllItems="True" PersistStateInCookie="True">

<Items>

<telerik:RadPanelItem runat="server" Text='<%$ Resources:Menu_Item_1 %>' PostBack="false" Expanded="true" >

<Items>

<telerik:RadPanelItem runat="server" Value="~/SystemSetup/Admin/Setup/CompanyList.ascx" Text='<%$ Resources:Menu_Item_1_1 %>' ImageUrl="~/SystemSetup/Resources/Images/ico_Company_16.png" Selected="true"></telerik:RadPanelItem>

<telerik:RadPanelItem runat="server" Value="~/SystemSetup/Admin/Setup/OperatorList.ascx" Text='<%$ Resources:Menu_Item_1_2 %>' ImageUrl="~/SystemSetup/Resources/Images/ico_Users_16.png"></telerik:RadPanelItem>

<asp:Panel runat="server" ID="P_Body" Width="100%" Height="100%"></asp:Panel>

...and the code to load the controls.

The User Control.

The Rebind javascript is to Rebind the RadGrid. The code behind just says:

Select Case e.Argument.Split("|")(1)

Case "RadGrid"

RadGrid.Rebind()

End Select

End Sub

..and the code behind to Update and trigger the Rebind.

Imports System.Data

Partial Class SystemSetup_UserControls_Setup_p_Company

Inherits System.Web.UI.Page

Private IdCompany As Guid = Guid.Empty

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not Request.QueryString("IdCompany") Is Nothing AndAlso Request.QueryString("IdCompany") <> "" Then

IdCompany = New Guid(Request.QueryString("IdCompany"))

End If

If Not IsPostBack Then

LoadItem()

End If

End Sub

Private Sub LoadItem()

Dim oDaOb As New RC.Protection.Company

oDaOb.PK.Add("IdCompany", IdCompany)

Dim oCo As DataRow = oDaOb.Get

CK_Active.Checked = oCo("Active")

T_1.Text = oCo("DescrShort")

End Sub

Protected Sub RadToolBar_ButtonClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadToolBarEventArgs) Handles RadToolBar.ButtonClick

Select Case e.Item.Value

Case "Save"

If IdCompany <> Guid.Empty Then

Dim oDaOb As New RC.Protection.Company

Dim oCo As DataRow = oDaOb.newDaObItem

oCo("IdCompany") = IdCompany

oCo("DescrShort") = T_1.Text

oCo("Active") = CK_Active.Checked

oDaOb.Upd(oCo)

Rebind()

End If

End Select

End Sub

Private Sub Rebind()

Dim Script As String = "window.opener.Rebind('RadGrid');"

Page.ClientScript.RegisterClientScriptBlock(Me.GetType, "Rebind", Script, True)

End Sub

End Class

So, to make a long story short, First Rebind ....works great...and then non more Rebind till Content Page full reload.

Any ideas ?
Thanks much as always.

Error loading RadChart image

Hello

I am using Radchart in a usercontrol for one of our application. The version of Telerik I have is 2012.1.215.40. I have Windows7 OS and IIS7. I have required Web.config entries in both System.Web and System.WebServer (Actually the entries were generated by the smarttag "Add RadChart HTTP Handler to Web.Config" option).

The radchart shows up fine for the first time. When i click the same page from the menu, the rad chart shows up a popup "Error loading RadChart image"

I tried the suggestions given by Evgenia in this post . Even setting usesession=false and setting the temp folder property resulting in the same sequence, first time it loads properly and second time when I load the page again it shows the error popup.

Please help

Thanks
Saran

Tab Strip with Multiple Windows

Hello,

Can someone explain or point me to a tutorial where I can have multiple windows nested in a tab strip.....with separate executing domains. So I guess what I'm asking is if there is a way to have one window nested in one tab using Chrome and the other tab/window using IE or Firefox?

So I might not be using the terms exactly correct so let me explain. I would like to have the tab strip with different tabs and the windows in that tab kept separate.

So user loads the default page and it has two buttons. New Tab Secured & New Tab Unsecured. The tab strip would be bound to an object and clicking either of the buttons would add another element to the collection so the tab strip would update with the new tab.

New Tab Secure would pop a modal window asking for credentials and a tab nickname (optional). Once entered it would go to an internal intranet site and the window of that tab would display the web page with the user logged in.

Now here is the trick that I am really unsure of.

New Tab Unsecure would open a new tab to the same site but of course we DON'T want the user logged in. PROBLEM. If for example IE is used then UNSECURED will be reading from the same cookies etc. and it will use the user credentials.

What I am desiring to provide to users of the system is the ability for them in one tab to have a administration login to make crud changes to the site. In the other tab see the impact of those CRUD operations.

Thank You
JB
