Any way to prevent using formatting?

I just want to use RadEditor as plain textbox without the user able to use ctrl-b to make certain characters bold because I will only be saving the text and not the formatting in the database.

PanelBar Load on demand with Multipage

Hi

I have a similar front-end to the Outlook Navigation demo for the panelbar using mutlipage controls, the different is they are separated by a splitter because we needed the splitter functionality.

In the solution we have we are using RenderSelectedPageOnly="true" on the multipage and using an AjaxManager so we can change the page the page when the panelbar is clicked. This was done because some of the pages called by the multipage can take a while to load and we didn't want them all loading at once.

However now each page is loaded when it is needed, which is all well and good but some of the users change page many times and others will stay on the same page.

Is there a way to have load on demand similar to the Tabstrip Demo that has the JS

<script type="text/javascript">
function onTabSelecting(sender, args)
{
    if (args.get_tab().get_pageViewID())
    {
        args.get_tab().set_postBack(false);
    }
}
</script>

So once a page is loaded it is not loaded again?

Thanks

odd behaviour - content of all the RadRotatorItems disapear

I'm experiencing an odd behavior from RadRotator.
I'm using the rotator control to build a custom Menu, but i'm having several problems.
The menu its defined in a .ascx file and some of items are being hide in .cs if the current user don't have de necessary permissions to view some of the items.

The problem is that if i set the visibility of the unwanted buttons (RadRotatorItem) to false, after de postback, the content of all the RadRotatorItems disapear.
Other strange behavior in the rotator that seems to cause all this problems, its the fact that de ID assigned to de RadRotatorItem in the .ascx its being overrided by other value. I have notice this in debug mode.

The only way i have found so far to acomplish the desired menu, was by creating in runTime in the OnInit event of the user control, the desired items in menu, but this is not very practical and it lacks in performance.

Had you or someone else already notice this strange behavior?
Can you provide some help or the best workAround?

Best Regards.

Selected days between months

Hi. I'm programming an application that works weekly, setting the raddatepicker mindate and maxdate between monday and next sunday (I'm from Spain). All works fine for me with the exception when weeks are between two months (i.e. mindate 01/31/2011 and maxdate 02/06/2011). I view in the calendar the final month selected (i.e. february), I can select the previous days of january but I want to view these days "active" (in bold style) like the rest of february days in the same week. How can I do that?

Thanks in advance.

RadGrid : Script controls may not be registered after PreRender.

Hello,

Let me explain my situation I can not solve that contains a RadGrid.

In the name WebUserControl ListTable.ascx I put inside a RadGrid that lists my records and a select button and Delete.

Then I create a control named ViewModules.ascx.

Inside ViewModules.ascx I create dynamically in my div PlaceHolder and using a variable in my QueryString, add dynamically in my ListTable.ascx PlaceHolder.

I put in my Session variable control ListTable.ascx then replaced in the page when I press a Delete event of RadGrid is within ListTable.ascx.

You find my code below because I can not provide an example as it uses several library of our platform.

Have you any idea how to make my event the delete button or trigger and be able to see more control in my page?

You will find 3 screenshots that show you the steps to view my shares.

This error only happens with all Telerik controls. If I use Microsoft's control that we have by default with Visual Studio, my control works without error.

Private Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init

If Me.IsPostBack AndAlso Not Session.Item("ViewModule") Is Nothing Then

ModuleItemPlaceHolder.Controls.Add(DirectCast(Session.Item("ViewModule"), Control))

Session.Remove("ViewModule")

End If

End Sub

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

If Not Me.IsPostBack Then

Dim site As CMS.Site.Item = CMS.Site.Provider.GetSite(Application)

If Not site Is Nothing Then

InitHeader(site)

If Me.ModuleType = [Module].Enumeration.ModuleType.None Then

' Loading module icons

ViewIcons(site)

Else

' Loading module

ViewModule(site)

End If

End Sub

Private Sub ViewModule(ByVal site As CMS.Site.Item)

Session.Remove("ViewModule")

If Me.ModuleType = [Module].Enumeration.ModuleType.None Then

Response.Redirect(String.Concat(site.Url, "/Gestion/"))

Else

Select Case True

Case Me.ModuleType = [Module].Enumeration.ModuleType.News OrElse Me.ModuleType = [Module].Enumeration.ModuleType.SlideShows OrElse _

Me.ModuleType = [Module].Enumeration.ModuleType.Testimonials OrElse Me.ModuleType = [Module].Enumeration.ModuleType.User

If Me.RecordID Is Nothing OrElse Not IsNumeric(Me.RecordID) Then

Dim ctrl As CMS.Controls.ListTable = DirectCast(LoadControl("~/CMSControls/Generic/ListTable.ascx"), CMS.Controls.ListTable)

ctrl.Module = Me.ModuleType

ctrl.EnableNewRecord = True

Dim handled As Boolean = False

RaiseEvent InitListTable(ctrl, handled)

Session.Add("ViewModule", ctrl)

ModuleItemPlaceHolder.Controls.Add(ctrl)

Else

End If

End Select

End If

End Sub

Problem with calculated column

Hi,
I'm having problem with calculated column in RadGrid (2010-02). Code:

...

<telerik:GridBoundColumn DataField="Quantity" HeaderText="Quantity" SortExpression="Quantity" UniqueName="colQuantity"></telerik:GridBoundColumn>

telerik:GridBoundColumn DataField="Price" HeaderText="Price" SortExpression="Price" UniqueName="colPrice" DataFormatString="{0:C}"></telerik:GridBoundColumn>

telerik:GridCalculatedColumn HeaderText="Total Cost" UniqueName="colTotalCost" DataType="System.Double" DataFields="Quantity, Price" Expression="{0}*{1}" />

...

Columns Price and Quantity are correct, without calculated column it is grid OK, but when I add it, I got cryptic error:

')' or ',' expected

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: Telerik.Web.UI.ParseException: ')' or ',' expected

Can anybody tell me, what's wrong?

Thank you,
Zdenek

RegularExpressionValidator not firing in panel

Hi,

I have a series of RegularExpressionValidators in an asp:panel which is marked Visible="false". This panel is later made visible and the page is updated with a RadAjaxManagerProxy control. When I later submit the form, using a button in the same panel, one of the RegularExpressionValidators does not fire. It does not even fire on the server-side. What can I do to resolve this?

Thanks.
