Hi

I am adding tabs to a radtabstrip dynamically and the tabs automatically break over multiple rows when they exceed the width of the tabstrip, which is nice. However when I select a tab in the top row it doesn't reorder - which is not so nice. Similar to this question. I have ReorderTabsOnSelect = true, is there something else I have to set?

Markup:

<telerik:RadTabStrip ID="RadTabStrip1" runat="server"

MultiPageID="RadMultiPage1"

SelectedIndex="0"

Skin="Vista"

ReorderTabsOnSelect="true"

Width="550px">

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="RadMultiPage1" runat="server"

SelectedIndex="0"

BorderStyle="Solid" BorderColor="Gray" BorderWidth="1px"

OnPageViewCreated="RadMultiPage1_PageViewCreated">

</telerik:RadMultiPage>

Source Code:

protected void Page_Load(object sender, EventArgs e)

{

if (Page.IsPostBack == false)

{

//get details of tabs

List<DummyObject> lstDummys = GetTabsFromDataBase(Request.QueryString["Tabs"]);

//loop through and add to page

foreach (DummyObject obj in lstDummys)

{

//add tab

RadTabStrip1.Tabs.Add(new Telerik.Web.UI.RadTab(obj._displayName));

//add pageview

RadPageView pageView = new RadPageView();

pageView.ID = obj._name;

RadMultiPage1.PageViews.Add(pageView);

}

Problem with RadList view and Embedded Grid

I am using the Telerik.Web.UI version 2010.3.1317.40
Visual Studio 2010 premium. .NET 4.0

I have a simple grid, embedded in a simple List View.

The data source for the list view is a Class Object.

When I get to the point that I am trying to get the list views key data value of customer number, it fails to set the parameter.

Let me post my code:

<%@ Page Language="c#" CodeBehind="AddressBook.aspx.cs" AutoEventWireup="True"

EnableViewState="true" Inherits="JDE.Reporting.AddressBook" MasterPageFile="~/MenuMaster.Master" %>

return;

int intID = (int)parentItem.GetDataKeyValue("CustomerNumber");

RadGrid rg_Contacts = (RadGrid)source;

rg_Contacts.DataSource = mcAddressBooks[intID].AddressBookContacts;

}

The error occurs in the Need Data source of the grid. When I try to set the parentiem, it is set to a value of null, or nothing.
I wind up with an error at the if(parentItem.DataItem == null) section of the code telling me that parentiem is null.

So, the code works for everything but this part, if I had code the intID to 0, and simply set the rg_Contacts.DataSource to mcAddressBooks[0].AddressBookContacts I get it to display, but simply with the 0 index of the class.

I would appreciate any help.

Specified cast is not valid error with raddatepicker

I created a custom edit form, and I have a raddatepicker which I'd like to bind to a date type field in my database.

<telerik:RadDatePicker ID="dtStart" runat="server" Width="200px" SelectedDate='<%# Bind("StartDate") %>'/>

when I try to access th edit form I receive this "Specified cast is not valid" error. Some of the values int he database are Null. I don't know if that has anything to do with it. Please advise.

DataList - ItemDatabound and TooltipManager

I've the following DataList:

<asp:DataList ID="dataListPhoto" runat="server" RepeatColumns="7" RepeatDirection="Horizontal" OnItemDataBound="dataListPhoto_ItemDataBound">

<ItemTemplate>

<asp:Image ID="imgButton" runat="server" ImageUrl='<%# Eval("ImageUrl") %>' Width="32"

Height="32" userName='<%# Eval("User") %>' />

</ItemTemplate>

</asp:DataList>

And want to show a tooltip on each Image (imgButton):

<telerik:RadToolTipManager ID="ttm" Height="200px" Width="350px" HideEvent="LeaveTargetAndToolTip"

RelativeTo="Element" Position="TopCenter" runat="server" Skin="Telerik" EnableShadow="true"

Animation="Fade" ShowDelay="1000">

<WebServiceSettings Method="GetHoveringText" Path="LinkHoveringAuthor.asmx" />

</telerik:RadToolTipManager>

In my code-behind I try to add each Images to RadToolTipManager's TargetCollections:

protected void dataListPhoto_ItemDataBound(object sender, DataListItemEventArgs e)

{

Image c = (Image) e.Item.FindControl("imgButton");

string value = c.Attributes["userName"];

ttm.TargetControls.Add(c.UniqueID, value, false);

}

But the Tooltip is only displayed for the first Image....

2nd question: in my LinkHoveringAuthor.GetHoveringText method I try retrieve the userName:

var contextDictionary = (IDictionary<string, object>)context;

if (contextDictionary["Value"] != null)

{

string name = contextDictionary["Value"

].ToString();

...

It works, but backslashes are omitted... :-|
For example, here:

ttm.TargetControls.Add(c.UniqueID, value, false);

if value="dom\user", in the webmethod, the "name" variable equals to "domuser"...

All Day Appointment

In this forum thread we're told that an appointment is 'All day' if the appointment starts at 12AM one day and ends at 12AM the next.

If I go to the Scheduler First Look demo and add an appointment in the all day section, the appointment is created with its start and end at 12AM on the SAME day. But if I edit one of the existing all day appointments, it is set up to start and end at 12AM on consecutive days.

What's right?

Unable to change EditModes in ConfigFile

I use RadEditorMOSS_5_8_4_Dev on WSS 3.0. I changed ListToolsFile.xml file:
<configuration>
<property name="EditModes">Design</property>
<property name="Height">240px</property>
<property name="Width">100%</property>
<property name="EnableResize">false</property>
</configuration>
The RadEditor render Design and Preview mode. Could you tell why RadEditor doesn't render only Design mode?

I found the answer in this post:

Hi,

I have a RadGrid with GridDateTimeColumn as below.

<rad:GridDateTimeColumn DataField="Date1" UniqueName="Date1" EditFormColumnIndex="0" DataFormatString="{0:d}" >
</rad:GridDateTimeColumn>

How can i check whether the entered date by user in the dateinput textbox is greater than or equal to todays date?Note user enters the date value instead of selecting from the datepicker

How can i have validations to the column during inserting and updating a record?

Regards

Tabstrip in tabwindow

Hi, I'm building a dotnetnuke module where I open a radwindow.
In the radwindow, there is a radtabstrip with a radpageview.

When I add 1 radpageview, there is no problem.
However, when I add a second one, it will give a javascript error saying error: invalid argument.
The error only happens in IE.

I also tried to directly use the tabstrip in the module (so not in the radwindow) and that seemed to work fine in IE.
So it seems to be a combination of the radwindow and the radpageview

Can anyone help me with this?

RadEditor's problem in IE8 within RadScheduler

Hi,

i have something really strange:
RadEditor doesnt show up in IE8 within AdvancedInsertTemplate or AdvancedEditTemplate from RadScheduler.
In Firefox 3.6.13, it looks better.
Here the code:

<telerik:RadPanelBar runat="server" ID="RPB_COB" Width="100%">

<Items>

<telerik:RadPanelItem Text="Contenu/Objectifs/Bilan" Expanded="True" runat="server">

<Items>

<telerik:RadPanelItem Value="COB" runat="server">

<ItemTemplate>

<telerik:RadEditor ID="RE_C" runat="server" EditModes="Design"

ToolbarMode="ShowOnFocus" Width="200" Height="200">

<Tools>

<telerik:EditorToolGroup Tag="Formatting">

<telerik:EditorTool Name="Bold" />

<telerik:EditorTool Name="Italic" />

<telerik:EditorTool Name="Underline" />

<telerik:EditorSeparator />

<telerik:EditorTool Name="ForeColor" />

</telerik:EditorToolGroup>

</Tools>

</telerik:RadEditor>

</ItemTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelBar>

In attachments, you can see some screenshots to see how it looks like within IE8 and FF3.6.13

Thank you in advance for your help and support.
