Chart XAxis doesn't start with the first Value

Hi everybody,

I am unable to configure RadHtmlChart to start with the First "DateTime" Value of a DataSet DataSource. Instead it keeps a empty area for a nearly whole year (see Picture). Any Idea how to solve this?

Thanks for your help

How to update an individual row column based on the values on the other columns row provided on the client side

Hi

I have a radgrid and radtimepicker on itemtemplates for each column,

the radtimepicker when loaded gets the time from the database, but when it's loaded, user can modify the time, I need to calculate the total time and display it on the end cell of each row for that row.

What's the best way to calculate this and display it on the radgrid on the client side.

Many thanks!

Postback firing form created event of Scheduler.

Is there anyway I can block this event<FormCreated> from postback of User control elements.
Currently I am having issue with it. Please check the image.

1. In the FormCreated event I have
if (e.Container.Mode == SchedulerFormMode.AdvancedInsert)
{
AgendaAppointment insertAppointment = (e.Container.FindControl("ucAppointmentInsert") as AgendaAppointment);
insertAppointment.CurrentUser = SessionManager.LoginUser;
insertAppointment.ActionDate = radSchAppTimeTodo.SelectedDate;

if (radSchAppTimeTodo.SelectedView == SchedulerViewType.DayView)
{
insertAppointment.TimeFrom = ((SchedulerAppointmentContainer)(e.Container)).Appointment.Start.TimeOfDay;
insertAppointment.TimeTo = ((SchedulerAppointmentContainer)(e.Container)).Appointment.End.TimeOfDay;
}
else
{
insertAppointment.TimeFrom = DateTime.Now.TimeOfDay;
insertAppointment.TimeTo = DateTime.Now.TimeOfDay;

}
}

and its working fine for the first them.
2. It sets the TIMEPICKER values of From and To and its difference are calculated and shown in Hours and Minue Integer text field which is correct.
3. But when I increase or decrease the Integer field then postback occurs and those initial values are set again. So If I increase the hours or minute it gets rollback to old values.

So is there anyway to block the form created event on postback.

RadWindow - issue in IE8

I have a page that opens a Radwindow as a popup confirm window before deleting an item. Only on IE8, the confirmation doesn't work. It keeps looping - you click confirm, the radwindow shows again, you click confirm again, the radwindow shows again....

On IE debugger, I get the script error "Object doesn't support property or method 'createEvent' ". I am not sure where this is getting fired off. Is there a way to fix this? Please let me know if you need any other information from me.

RadSpell in RadWindow causes error

Here are my initial steps:

1) Create a fresh .NET 4.5 "ASP.NET Web Forms Application" in Visual Studio 2012
2) Upgrade the project to a Telerik RadControld project, using v 2013.3.1015.45
3) Place the following markup on Default.aspx:

<%@ Page Title="Home Page" Language="VB" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Default.aspx.vb" Inherits="RadSpellTestApp._Default" %>

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

<script type="text/javascript">

function spellCheck(elID) {

var spell = $find(elID);

spell.startSpellCheck();

return false;

}

</script>

</asp:Content>

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

<asp:Button ID="btnOpen" runat="server" Text="Open Window" />

<trk:RadWindow ID="rdwElement" runat="server" Behaviors="Move,Resize" Width="525" Height="390" Modal="true" VisibleStatusbar="false" >

<ContentTemplate>

<trk:RadAjaxPanel ID="pnlElement" runat="server">

<trk:RadTextBox ID="txtText" runat="server" Rows="7" TextMode="MultiLine" Width="474px" />

<trk:RadSpell ID="rdSpell" runat="server" ButtonType="None" ControlToCheck="txtText" />

<asp:Image ID="imgSpell" runat="server" ImageUrl="~/Images/spellcheck.gif" Style="cursor: pointer;" ToolTip="Spell check" />

</trk:RadAjaxPanel>

<br />

<asp:Button ID="btnClose" runat="server" Text="Close Window" />

</ContentTemplate>

</trk:RadWindow>

</asp:Content>

This is the code-behind:

Public Class _Default

Inherits Page

Private Sub btnOpen_Command(sender As Object, e As CommandEventArgs) Handles btnOpen.Command

rdwElement.VisibleOnPageLoad = True

End Sub

Protected Sub btnClose_Command(ByVal sender As Object, ByVal e As CommandEventArgs) Handles btnClose.Command

rdwElement.VisibleOnPageLoad = False

End Sub

Protected Overrides Sub OnPreRender(e As EventArgs)

MyBase.OnPreRender(e)

imgSpell.Attributes("onClick") = "spellCheck('" & rdSpell.ClientID & "')"

End Sub

End Class

If I open and then immediately close the RadWindow, I don't get any errors. However, if I:

1) Open the Window
2) Spell-check the textbox.
3) Close the Window

I get a javascript error:

0x800a1391 - JavaScript runtime error: '$telerik' is undefined

This same setup did not cause me problems in .NET 4.0. I can send the corresponding .NET 4.5 .zip file if necessary. Thank you!

Pasting images in Rad Editor on old version of Telerik

Hi,

We are using Telerik version 2012.1.411.40. We have placed a RadEditor in one of our pages and found out that we cannot paste an directly directly onto RadEditor. After reading through some of the Telerik post we figured out that this issue is resolved in the newer version of Telerik dll's but the issue is that we cannot upgrade the telerik dll's at this moment as we are loosing the UI customization that we did.

Is there a way we can fix the issue of pasting images in RadEditor in older version of telerik i.e 2012.1.411.40?

Thanks
Varun

Display Different Text in ComboBox Header/DropDown

I would like to be able to display different text in the combo box visual portion and it's dropdownlist. Example: I have a combobox with the following items

Supervisor
Superintendent
Project Lead
Project Manager
Program Manager

So when you select the combobox you get the dropdown with those items. But then when you select Supervisor, instead of displaying Supervisor on the screen it now displays a two digit code such as "21". When clicking the combo box that displays "21" I'd like it to still show the above list items.

Is this possible?

Cur appointment height

Hi,

I'm using RadScheduler with document mode of IE9.
Each appointment is cut, with the height of its containing <td>, and not the height by its duration.

If I change to IE7 document mode, it looks OK.

If I'm on IE9 mode, but removing {position: relative} from the class .rsWrap, the height is OK, but the width is now all over the week, and not over one day.

Screenshots attached for every scenarios.
I'm using version 2013.2.717.40.

Thanks,
Guy.
