Validating Data on a Property Level don't show error message

Hi

Validating data on a property level causes a red rectagle around the cell but no error message is available.
Below an example and attached the snapshot.

<Window xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" x:Class="TestRadGridView.MainWindow"

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

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

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

<Grid>

<telerik:RadGridView Name="gridView"/>

</Grid>

</Window>

and the code behind

using System;

using System.Collections.Generic;

using System.Windows;

using System.Windows.Documents;

namespace TestRadGridView

{

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

gridView.ItemsSource = User.AsList();

}

class User

{

private string _username;

public string Username

{

get { return _username; }

set { if ( _username == null) _username=value; else throw new Exception("Username can't be changed"); }

}

public string Email { get; set; }

public static List<User> AsList()

{

List<User> list = new List<User>();

list.Add(new User() {Username="Username1", Email="username1@email"});

list.Add(new User() {Username="Username2", Email="username2@email"});

return list;

}

I'm using WPF Q2 2010 SP1 on Windows 7.

Thanks
Ivano

CurrentItem on Tree?

Hi!

What is the correspondence of the RadGridView and the RadTreeView??

Not the SelectedItem, but the CurrentItem, BECAUSE:

There is no "SelectionChanging", so I'm forced to code myself the revert to the previous element if my conditions aren't satisfied.

Then I was doing something like:

private void uxRadTreeView_SelectionChanged(object sender, SelectionChangedEventArgs e)

{

if (!isReverting && MyConditionsHere){

isReverting = true;

MainTree.SelectedItem =e.RemovedItems[0];

}

if(isReverting)

isReverting = false;

}

The object seems to be "selected", but doesn't change:

image of the selected item problem

File2 is the File on which I've made a "MainTree.SelectedItem= e.RemovedItems[0]"

The File1 is the e.AddedItem[0].

Without the SelectedItem manipulation, I don't see the dashed border on it.

Thank you.

SelectionChanging?

Hi!

I actually need to permit to an user to change of row only when some conditions have been met.

I've seen a "SelectionChanged", But with this it's too late, the row has already been changed.

So how can I catch this event and cancel it if I want it?

Thank you

Insert/Edit ability?

I see the quick ability of BeginInsert() which adds to the *end* of the list and starts an edit.

How about the ability to INSERT under the current row (and optionally edit).

I realize this control is new, but I see very little examples to assist. When I try modifying the Items it states it is in use. When I reflect the BeingInsert, there's lots of internal calls to add at the end.

How does one achieve this?

later and/or related: the ability to insert branches, to delete branches.

Thanks,

Multiple Minimized Tileview Rows

Hey guys,

I really love the capabilities of the tileview; however I was wondering if it is possible to have multiple minimized rows at the bottom (or side if need be)?

I have attached what I would like the layout to look like ideally, please let me know if this is possible.

Many thanks in advance =)

Regards,

Jess

Mainpage.xaml doesn't effect

I download a trial version of RadControls for WPF Q2 2010 SP1 and trying to run the sample program. It works. But when I try to change the main interface, it's doesn't work at all.

The main page just use the user control in QuickStart_WPF.MainPage.xaml, right? I change the user control, it looks like it's never been called.

I'm confused.

Re : Telerik Grid View (RadGridView) ItemSource and Scrollbar

Hii All,
I am using RadGridView for displaying some of the records in my application. i have one datasource in which the records are available, which i want to display in the grid.now from code behind i am binding this gridview by using code "grid.itemsource=dataset;"
i have 20 columns in my dataset.
In my application all the columns are not visible only few column are visible in the telerik datagrid depending on the datagrid width.
in this case datagrid must have a horizontal scrollviewer which must be visible, if no. of columns exceeds depending on width of grid.

now if i will try to sort datagrid by any column then horizontal scrollviewer enables and i am able to see all the columns by using this scrollviewer.

provide/update telerik datagrid code for above mentioned problem. so that if the telerik datagrid's itemsource changes it should automatic provide the scrollviewer for viewing all the columns.

thanks
regards
