Hi.
I've two time pickers, one to enter a "start time" and another for the "end time". I set both with 00:30:00 interval. First one StartTime is 00:00:00 and EndTime is 23:30:00. Second one StarTime is 00:30:00 and EndTime must be 00:00:00 (or 24:00:00) but it doesn't work. If I try to set 23:59:59, due to Interval I can't see in the timetable this last one. How I can set and EndTime to 00:000:00 (or view 23:59:59 with 30 minutes Interval) without change the day?

Thanks in advance.

Potential bug in radspell

I have the following requirement:

Radspell control to spell check a textbox
Radspell supports English and French languages
When an English user views the page, the English language is preselected from the dropdown, French language is selected otherwise

I got the above working. However, when a French users enters purely English text in the textbox and select English from the drop down, the control still do the spell checking as if French is selected. I am using version 2011.1.519.40 and asp.net 4.0.

I noticed that the issue occurs when only if I set the DictionryLanguage property

Here is the code I have used

Public Class _Default

Inherits System.Web.UI.Page

Dim language As String

Protected Sub RadSpell1_Init(sender As Object, e As EventArgs) Handles RadSpell1.Init

RadSpell1.SupportedLanguages = New String() {"en-us", "English", "fr-fr", "French"}

If language = "1" Then

RadSpell1.DictionaryLanguage = "fr-fr"

Else

RadSpell1.DictionaryLanguage = "en-us"

End If

End Sub

Private Sub Page_PreInit(sender As Object, e As System.EventArgs) Handles Me.PreInit

If Request.QueryString.AllKeys.Contains("lang") Then

language = Request.QueryString("lang").ToString

End If

End Sub

End Class

<%@ Page Title="Home Page" Language="vb" MasterPageFile="~/Site.Master" AutoEventWireup="false"

CodeBehind="Default.aspx.vb" Inherits="TelerikRadSpellPOC._Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">

</asp:Content>

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<h2>

Welcome to ASP.NET!

</h2>

<div>

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

<telerik:RadSpell ID="RadSpell1" runat="server" ControlToCheck="TextBox1"

/>

</div>

</asp:Content>

Please let me know if I missed anything

I'm using a radnumeric textbox as a template control in a radgrid which is in a radajaxpanel. The radnumerictextbox doesn't increment or decrement. The grid has paging and if i move to another page the radnumeric textbox works. Also if I take the radajax panel off it also works. I'm using controls in ASP.NET Ajax Q2 2010 SP1 (Version 2011.1.519)

Treeview not showing up properly

Hello,

I have a problem with treeview display.

Here's the aspx..

<telerik:RadTreeView ID="radTVFolders" runat="server" AccessKey="T" Skin="Default" EnableEmbeddedSkins="false" CollapseAnimation-Type="Linear" ExpandAnimation-Type="Linear" EnableDragAndDrop="false" ShowLineImages="False" OnClientNodeClicked="ClientNodeClicked" OnClientNodeClicking="ClientNodeClicking">
<CollapseAnimation Type="OutSine" />
</telerik:RadTreeView>

Also, please find attached the screenshot of the weird treeview display. Since the treeview does not show up properly it throws javascript error "this._element is null or not an object" on mouseover of the nodes.

When I see the view source of the page, I see that the div tag is not well formed. It comes up as "<divclass="rtMid">" for the node which breaks.

The issue is random. Can you please suggest?

Thanks in advance

[Solved] DisplayToUtc

I've recently been updating some of my out dated scheduler code to use the newer UI dll's as well as newer custom advanced from templates.

I've noticed the use of this DisplayToUtc method in some area.

I was hoping someone could expand on the little documentation on this method and perhaps comment on where and how it should be used.

I just did a test in the save click method of the advanced form. I chose Aug 25th at 9am as the start date.

>>> apt.get_start()

Date {Thu Aug 25 2011 09:00:00 GMT-0400 (Eastern Daylight Time)}

>>> this._scheduler.displayToUtc(apt.get_start())

Date {Thu Aug 25 2011 09:00:00 GMT-0400 (Eastern Daylight Time)}

So no change in that example.
I'm wondering in what cases should I xpect there to be a change and how this method was intended to be used

regards,
roatin

[Solved] Items dissapear and other items get copied after postback

Hi,

Im running in some very strange behavior with the radcombobox (Telerik 2011Q2).
I have 2 dropdownlist and a button. Changing the selecting of the 1st box alters the content in the 2nd box. the button does nothing special, just a postback.

When i change the selection of the first box, the 2nd box gets filled correctly. But when i push the button, the contents of the 2nd box gets alterd, the fist 2 items dissapear and the last 2 get copied and are added to the back.

aspx

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<telerik:RadComboBox ID="ddlbInstituut" runat="server" AutoPostBack="true" />

<telerik:RadComboBox ID="ddlbAfdeling" runat="server" CheckBoxes="true" Width="300px"

/>

<asp:Button ID="Button1" runat="server" Text="Button" />

vb.net

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

If Page.IsPostBack = False Then

vulInstituutDropdown()

End If

End Sub

Sub vulInstituutDropdown()

Dim dsInstituten As DataSet

dsInstituten = SqlHelper.ExecuteDataset(Conn, "SP_GetInstituut")

With ddlbInstituut

.DataSource = dsInstituten

.AutoPostBack = True

.ID = "ddlbInstituut"

.DataTextField = "inst_omschrijving"

.DataValueField = "inst_id"

.DataBind()

End With

vulAfdelingDropdown()

End Sub

Private Sub vulAfdelingDropdown()

Dim dsAfdelingen As DataSet

dsAfdelingen = SqlHelper.ExecuteDataset(Conn, "SP_GetAfdelingen", ddlbInstituut.SelectedValue)

With ddlbAfdeling

.Controls.Clear()

.ID = "ddlbAfdeling"

.DataSource = dsAfdelingen

.DataTextField = "afde_omschrijving"

.DataValueField = "afde_id"

.DataBind()

End With

End Sub

Protected Sub ddlbInstituut_SelectedIndexChanged1(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlbInstituut.SelectedIndexChanged

vulAfdelingDropdown()

End Sub

The storedprocedures always cough up the correct data.

When useing radListBox, same problem, enabeling or disabeling the checkboxes makes no difference, when useing conventional dropdownlists, no problems whatsoever.

Please help.
