after installing Q1 2011 SP1, VS toolbox is empty!

I'm hoping for some troubleshooting guidance. I just installed RadControls for ASP.NET AJAX Q1 2011 SP1. While there is a Telerik menu, the only menu item in it is "About".

Shouldn't there be something about Upgrade Project...?

Right now we have the Telerik.Web.UI.dll in our BIN directory. Should manually replace that (just copy / paste over it), or is there a "better" way to make sure references and all that are all squared away?

Load User Control After Page Load with Progress Bar

I have a user control that is taking a long time to load (15-20 seconds) mainly because there are many data entry fields and loops to load each field. It is optimized as best I can (one db roundtrip, caching, etc.), but it has nested RadTabStrip controls and other things.

How can I allow a page to load and then, after it has loaded, fire off a server-side (update panel?) call to load my custom user control? Ideally, I want a progress bar that I can interact with as the user control loads.

So, in theory:

1. Page loads.
2. OnLoad, the user control is initialized.
3. A progress bar is displayed in place of the user control.
4. Events fired in the child controls bubble up to the Page to update the progress bar.
5. After the control is loaded, the progress bar is removed and the user control is displayed.

Is this possible using the TelerikRadAjaxManager and Telerik progress bar?

My control events inside panel aren't firing

I have a pretty simple page. I have an Ajax Manager, two Ajax Panels and a very few other controls outside of either panel. In the top Panel, it is just two radio buttons. Depending on which button is clicked, I want the bottom panel to hide or unhide using the panel's .visible property. The default is hidden when the page loads. I have breakpoint in my code (VS2010) for the _CheckedChanged event of both radio buttons and when I click the radio buttons, neither one seems to fire these event.

All I want to do is show or hide the lower panel full of controls.

AjaxManger code:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="rbDonationTypeGeneral">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pnlILMO" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="rbDonationILMO">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pnlILMO" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

Radio-button Panel: (that hides/unhides ILMO panel below)

<telerik:RadAjaxPanel ID="pnlDonationType" runat="server" height="59px"

width="300px">

<asp:RadioButton ID="rbDonationTypeGeneral"

runat="server"

Checked="True"

GroupName="grpDonationType"

Text=" General Donation" />

<br />

<asp:RadioButton ID="rbDonationILMO"

runat="server"

GroupName="grpDonationType"

Text=" In Loving Memory Of..." />

</telerik:RadAjaxPanel>

ILMO Panel: (this is the panel that hides or un-hides depending on which radio button is selected above)

<telerik:RadAjaxPanel ID="pnlILMO" runat="server" height="373px" width="717px" Visible="False">

A charitable contribution has been made to the Foundation:

Event code of the radio buttons:

End Sub

Protected Sub rbDonationILMO_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles rbDonationILMO.CheckedChanged

pnlILMO.Visible = True

End Sub

Can someone please tell me what I'm missing or doing wrong. Thanks.

related menus bound to a ASPNETSqlSiteMapProvider

I have two related menu's a horizontal top menu and a vertical childmenu

In the top menu I only want to show one level of items ie. those that are child of root! (level1)
and in the vertical menu I want to show child items of current selected item (level2,3 and 4 in a treeview)

when I select an item level1 in the radmenu it gets highlighted and when I select an item level 2,3 or 4 in the treeview I want the level 1 parent item in the radmenu to be highlighted as this does work when I dont have MaxDataBindDepth="1" in the Radmenu but then I get the dropdown menu showing all child items which I dont want. Is there a way of solving this with another function than MaxDataBindDepth="1" I saw MaxLevel in the documentation but it didnt work. (My client has RadControls ASP.NET-AJAX 2011Q1)

(MasterPage)

<

tr:RadMenu ID="mnuNavRoot" runat="server" MaxDataBindDepth="1" Flow="Horizontal" DataSourceID="smdsNav" />

<asp:SiteMapDataSource ID="smdsNav" runat="server" ShowStartingNode="false" SiteMapProvider="AspNetSqlSiteMapProvider" />

(ASPX Page)

<tr:RadTreeView ID="tvNaviMain" runat="server" ShowLineImages="false" DataSourceID ="smds1">

</tr:RadTreeView >

<asp:SiteMapDataSource ID="smds1" runat="server" ShowStartingNode="false" SiteMapProvider="AspNetSqlSiteMapProvider" />

If root = true Then

tvNaviMain.MaxDataBindDepth = 1

Else

smds1.StartingNodeOffset = 1

End If

Any suggestions?

When i want to delete an instance of a recurring event, the fuction "theScheduler_AppointmentUpdate" will fired . My code is as bellow ,

void theScheduler_AppointmentUpdate(object sender, AppointmentUpdateEventArgs e)

{

Appointment appointment = e.Appointment; 



  // People resizing 

  SPListItem li = GetListItem(appointment);

if (appointment.RecurrenceState == RecurrenceState.Master)

RecurrenceRule recRule;

RecurrenceRule.TryParse(appointment.RecurrenceRule, out recRule);

if (recRule != null && recRule.Exceptions.Count > 0)

{

// The last exception is the DateTime of the deleted appointment

"window.open" is not working using radtooltipmanager control

PHello,

I have a problem in opening a window form after opening the radtooltipmanager..
Please view the webpage http://israel-jewelry-center.com/Pages/Categories/Bracelets.aspx. By coming over any item, a radtooltipmanager opens, and by clicking the big image, a radwindow opens.
The requirements is to change the radwindow control with a window (using the javascript command window.open).
I added the following code to the Bracelets.aspx page:

function CloseActiveToolTipAndOpenUrl(path) {

setTimeout(function () {

var tooltip = Telerik.Web.UI.RadToolTip.getCurrent();

if (tooltip) {

tooltip. hide();

window.open(path, "mywindow", "status=1");

}

}, 1000);

}

But unfortunatily, just the command tooltip.hide() is executed, but the window.open(path, "mywindow", "status=1") didn't.
I dont understand why is that.

Please download the sample application from http://www.israel-jewelry-center.com/ToolTipSampleApplication.rar

Please, I need your help,
It is appreciated to send me the modified code with an explaination,

Regards,
Bader
