RadScheduler stopped working after upgrade

I had a RadScheduler in place and working under version 2011.3.1115.40 , upgraded to 2013.3.1015.40 and now the control has stopped working. Specifically, when I click the recurrence checkbox, the associated panel does not open.

I'm getting a JS error when opening the page that is indicating that there are problems in the "AdvancedForm.js" file. The get_element() call is failing.

if ($telerik.isIE) {

var textarea = this._getSubjectTextBox().get_element();

textarea.style.cssText = textarea.style.cssText;

}

Is there an ungraded version of the file I should be using with 2013.3.1015.40 ?

Add a CheckBox to the Appointment

Hi,

I'm trying to add a CheckBox to the Edit and Insert forms. I've added a usercontrol AdvancedForm.ascx

<%@ Register TagPrefix="scheduler" TagName="AdvancedForm" Src="AdvancedForm.ascx" %>

<AdvancedEditTemplate>

<scheduler:AdvancedForm runat="server" ID="AdvancedEditForm1" Mode="Edit" Subject='<%# Bind("Subject") %>'

Description='<%# Bind("Description") %>' Start='<%# Bind("Start") %>' End='<%# Bind("End") %>' AllUsers='<%# Bind("AllUsers") %>'/>

</AdvancedEditTemplate>

<AdvancedInsertTemplate>

<scheduler:AdvancedForm runat="server" ID="AdvancedInsertForm1" Mode="Insert" Subject='<%# Bind("Subject") %>'

Start='<%# Bind("Start") %>' End='<%# Bind("End") %>' Description='<%# Bind("Description") %>' AllUsers='<%# Bind("AllUsers") %>'  />

</AdvancedInsertTemplate>

And in the AdvancedForm.aspx, I've added this code

<asp:CheckBox ID="cboxAllUsers" runat="server" Text="All Users" />

[Bindable(BindableSupport.Yes, BindingDirection.TwoWay)]

public bool AllUsers

{

get

{

return cboxAllUsers.Checked;

}

set

{

cboxAllUsers.Checked = value;

}

I'm getting this error

DataBinding: 'Telerik.Web.UI.Appointment' does not contain a property with the name 'AllUsers'.

How do I fix this error?

Thanks!

Telerik RadGrid Error - GridPagerStyle does not have PageSizeControlType

A co-worker gave me a modified version of a file and now I can't get the project to compile in Visual Stuio. As far as I know, we're both using the same source code. I tried copying the Telerik .dll files from the server (where the code is working) and referencing those files, but I am still getting the same error. The version of my Telerik .dll files is 2012.1.215.40. Can you help me with this?

The errors I am getting are

Type 'Telerik.Web.UI.GridPagerStyle' does not have a public property named 'PageSizeControlType'.

Content ('</PagerStyle>') does not match any properties within a 'Telerik.Web.UI.GridTableView', make sure it is well-formed.

The error is from this line:

<PagerStyle PageSizeControlType="RadComboBox"></PagerStyle>

If I comment out that line, I get a whole host of other error messages that are similar (Telerik.XXX does not have a public property named YYY).

Can't Get Sorting to Work

I am using ASP.NET C# for my RadGrid and cannot get sorting to work. I have tried a couple of different ways to do it that I have found on this site, and some code from other sites, but the grid remains sorted the default way each time I try. Someone please help!

<telerik:RadGrid runat="server" ID="radProductsGrid" Skin="Default" AllowSorting="true" AllowPaging=

"true"

OnSortCommand="radProductsGrid_SortCommand" OnNeedDataSource="radProductsGrid_NeedDataSource"
AutoGenerateColumns= "false" GridLines="None" ShowGroupPanel="false" PageSize="100">

<MasterTableView Width="100%" AllowMultiColumnSorting="false" AllowNaturalSort="false"
AllowCustomSorting="true" AllowSorting="true" AutoGenerateColumns="false">

<Columns>

<telerik:GridBoundColumn ReadOnly="true" AllowFiltering="true" SortExpression="ItemNumber"
DataField="ItemNumber" HeaderText="Item Number" UniqueName="ItemNumber">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn ReadOnly="true" AllowFiltering="true" SortExpression="ProductName"
DataField="ProductName" HeaderText="Product Name" UniqueName="ProductName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn ReadOnly="true" AllowFiltering="true" SortExpression="CategoryName"
DataField="CategoryName" HeaderText="Category Name" UniqueName="CategoryName">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

protected void radProductsGrid_SortCommand(object sender, GridSortCommandEventArgs e)

{

GridTableView tableView = e.Item.OwnerTableView;

if (e.SortExpression == "ItemNumber")

{

e.Canceled = true;

GridSortExpression expression = new GridSortExpression();

expression.FieldName = "ItemNumber";

if (tableView.SortExpressions.Count == 0 || tableView.SortExpressions[0].FieldName

                        != "ItemNumber")

{

expression.SortOrder = GridSortOrder.Descending;

}

else if (tableView.SortExpressions[0].SortOrder == GridSortOrder.Descending)

{

expression.SortOrder = GridSortOrder.Ascending;

}

else if (tableView.SortExpressions[0].SortOrder == GridSortOrder.Ascending)

{

expression.SortOrder = GridSortOrder.None;

}

tableView.SortExpressions.AddSortExpression(expression);

tableView.Rebind();

}

[Solved] RadDatePicker - selecting a day is getting the previous day

As a developer, you need to consider the various time zones which your users are located on.

Some countries use the Daylight saving time (DST) /summer time/ which is the practice of advancing or adjusting backward clocks one hour near the start of a temperate mid-season (spring or autumn). Unfortunately, this adjusting is error-prone to software components and leads to unwanted behavior when using a RadDatePicker.

For instance, let’s assume that you have a web site for renting out various halls or principal rooms for meetings and social affairs, and you use a RadDatePicker to schedule the event date. I am a user from Brazil and with meu amor decided our wedding date to be on October the 20^th. However, every time I select this date, the picker re-selects it to be the 19^th. I contact you, the web administrator, and ask you “Does destiny want to prevent me from making a big mistake or is this a bug? What is happening, amigo?”

Here is the explanation:

Most probably, I have a Brazilian culture set on my computer:

As noticed in the image, the clocks will be advanced by 1 hour on that date. And since the RadDatePicker takes the zero hour by default, it is actually still on the previous day, because the 20^thstarts at 01:00 o’clock. To work around this issue, you can use the client side events of the picker:

<telerik:RadDatePicker ID="RadDatePicker1" runat="server">

<DateInput runat="server">

<ClientEvents OnValueChanging="valueChanging" OnValueChanged="valueChanged" />

</DateInput>

</telerik:RadDatePicker>

JavaScript:

var selectedValue = null;

var isDST = false;

function valueChanging(sender, args) {

if (isDST) {

args.set_newValue(selectedValue + " 01:00 AM");

isDST = false;

}

selectedValue = args.get_newValue();

}

function valueChanged(sender, args) {

if (selectedValue) {

if (selectedValue.indexOf(args.get_newValue()) < 0) {

isDST = true;

sender.get_owner().set_selectedDate(); // used only to trigger selecting event

}
