Hi guys,

we start working on an agenda project and I'm looking for a specific component. In my project, I want to give to the user the possibility to enter a search criteria to find all free spots matching theirs search criterias in the agenda and I want to show them the search results as you can see in the screenshot I attached.

The vertical representation should be: am, pm and evening or monday..sunday depending of what they want to see.

Before renewing with Telerik, I have to be sure that Telerik have the right component for us.

Thank's guys...

RadScheduleView swap

I'm swapping themes from ExpressionDark to Windows8Touch for a project. The swap from ExpressionDark to Windows8Touch isn't seamless.

In the Telerik.Windows.Controls.ScheduleView.xaml file (Windows8Touch) I see a reference to telerik:Windows8TouchResource, is this Windows8TouchResource a file I should have local on my computer?

I would appreciate any help on this, thanks.

GridViewDataColumn.IsReadOnly binding incorrectly

I'm trying to bind the IsReadOnly property on a GridViewDataColumn, but it appears to be binding to the DataContext of the GridView instead of the context created by the ItemsSource. My XAML:

<Window x:Class="RadGridViewTesting.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

Title="MainWindow" Height="350" Width="525">

<Grid>

<telerik:RadGridView x:Name="radGridView"

AutoGenerateColumns="False"

ItemsSource="{Binding Path=EmployeeList}">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=FirstName}"

Header="First Name" UniqueName="FirstName"

IsReadOnly="{Binding Path=ReadOnly}"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

</Window>

Simple code behind to create the ViewModel DataContext:

namespace RadGridViewTesting

{

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

DataContext = new ViewModel();

}

And finally the ViewModel:

namespace RadGridViewTesting

{

public class Employee

{

public string FirstName { get; set; }

public bool ReadOnly { get; set; }

}

class ViewModel

{

List<Employee> _myList;

public ViewModel()

{

_myList = new List<Employee>();

_myList.Add(new Employee() { FirstName = "John", ReadOnly = true });

_myList.Add(new Employee() { FirstName = "Jane", ReadOnly = false });

_myList.Add(new Employee() { FirstName = "Jack", ReadOnly = true });

}

public List<Employee> EmployeeList { get { return _myList; } }

}

This results in the following output message:

System.Windows.Data Error: 40 : BindingExpression path error: 'ReadOnly' property not found on 'object' ''ViewModel' (HashCode=24397644)'. BindingExpression:Path=ReadOnly; DataItem='ViewModel' (HashCode=24397644); target element is 'GridViewDataColumn' (HashCode=15286079); target property is 'IsReadOnly' (type 'Boolean')

It should be looking for "ReadOnly" on the "Employee" object (same object it's binding the DataMemberBinding to) rather than the "ViewModel" object. The only work-around I've found is to set up DataTriggers for every column I need to be able to disable (in my case several) as mentioned in this post, but that certainly isn't elegant. Is there another known solution?

Thanks,
Louis
