[Solved] RadExpander and RadScheduler side by side

Hi

I am having serious problems performing something that seems quite simple.
I want a RadScheduler filling the form, and a RadExpander to the right of it. When I expand the Expander, the Scheduler should decrease its size accordingly.
When I try this with the Expander on top, it works as intended, but when I put the expander to the right, the scheduler just will not stretch over the form. It stretches well vertically, but not horizontally.
I believe I have altered the directions etc on the components as I should, but without any luck.

This is my very small form:

    
            <Page x:Class="RadControlsWpfBrowserApp2.Page1" 
        
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        
                Title="Page1" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">  
        
                <Grid> 
        
                    <StackPanel Orientation="Horizontal">  
        
                        <telerik:RadScheduler Name="radScheduler1" HorizontalAlignment="Stretch" /> 
        
                        <telerik:RadExpander ExpandDirection="Left" HorizontalAlignment="Right">  
        
                            <telerik:RadExpander.Header> 
        
                                <Grid HorizontalAlignment="Stretch">  
        
                                    <Grid.ColumnDefinitions> 
        
                                        <ColumnDefinition Width="Auto" /> 
        
                                        <ColumnDefinition Width="*" /> 
        
                                    </Grid.ColumnDefinitions> 
        
                                    <TextBlock Text="Header" /> 
        
                                    <Rectangle Grid.Column="1" Margin="5,0,0,0" VerticalAlignment="Center" Height="2" Fill="Gray" /> 
        
                                </Grid> 
        
                            </telerik:RadExpander.Header> 
        
                            <StackPanel Orientation="Vertical" > 
        
                                <Ellipse Width="33" Height="33" Margin="5" Fill="Yellow" /> 
        
                                <Ellipse Width="33" Height="33" Margin="5" Fill="Blue" /> 
        
                                <Ellipse Width="33" Height="33" Margin="5" Fill="Red" /> 
        
                            </StackPanel> 
        
                        </telerik:RadExpander> 
        
                    </StackPanel> 
        
                </Grid> 
        
            </Page>

ScrollIntoView not working

Hi,

I have added a RadGridView and populated some data. Now i am giving an option to the user to select the column, i.e. when the user selects a column, we would make that record as selectedItem and scroll to that record.
I have used the following code :

this

.radGridView1.SelectedItem = radGridView1.Items[RecordNumber-1];

this.radGridView1.ScrollIntoView(this.radGridView1.SelectedItem);

The correct item is selected, but the scroller is still pointing to the first one.
I am attaching the screen shot for reference.

Regards,
Prithvi

RadTreeViewItem.RootItem not returning correct item

The RadTreeViewItem.RootItem property used to return an item's highest ancestor node (as of version 2009.1103), but in the current version (2010.0309) it always returns a reference to itself. Does anyone else see this behavior?

Here's a very simple example:

                        <StackPanel>         
                    <telerikNavigation:RadTreeView x:Name="tree"/>         
                    <TextBlock x:Name="msg"/>         
                </StackPanel>         
                     

And the code behind:

                            private void Window_Loaded(object sender, RoutedEventArgs e)         
                    {         
                        RadTreeViewItem item1 = new RadTreeViewItem() { Header = "item1" };         
                        RadTreeViewItem item2 = new RadTreeViewItem() { Header = "item2" };         
                        RadTreeViewItem item3 = new RadTreeViewItem() { Header = "item3" };         
                     
                        tree.Items.Add(item1);         
                        item1.Items.Add(item2);         
                        item2.Items.Add(item3);         
                     
                        // item3.RootItem returns item1 in 2009.1103 version (CORRECT)         
                        // item3.RootItem returns item3 in 2010.0309 version (WRONG)         
                        msg.Text = "item3.RootItem is " + item3.RootItem.Header.ToString();         
                     
                        tree.ExpandAll(); // <-- This also doesn't seem to be working         
                        item1.ExpandAll(); // <-- Neither does this         
                    }

[Solved] TreeInComboBox: Only allow lowest level selection

I am using the sample TreeView In ComboBox from this blog (http://blogs.telerik.com/valerihristov/posts/09-08-27/treeview_in_combobox_take_3_silverlight_3_wpf_and_radcontrols.aspx) and it looks really good. Now I would like to modify it a little by only allowing selection of the lowest level item from the tree view. How can I disable selection of higher level items but still allow the items to be collapsed?

In Edit mode Tab works does not save on clicking elsewhere

Hi,
I am using Grid view and have a column defined as below.

    
            <telerik:GridViewDataColumn UniqueName="SiteName" Header="SiteName" DataMemberBinding="{Binding SiteName, Mode=TwoWay}"  Width="120" > 
        
                                        <telerik:GridViewDataColumn.CellTemplate> 
        
                                            <DataTemplate> 
        
                                                <TextBlock Text="{Binding SiteName}" /> 
        
                                            </DataTemplate> 
        
                                        </telerik:GridViewDataColumn.CellTemplate> 
        
                                        <telerik:GridViewDataColumn.CellEditTemplate> 
        
                                            <DataTemplate> 
        
                                                <TextBox Text="{Binding SiteName, Mode=TwoWay}" MaxLength="20" Loaded="Editor_Loaded" /> 
        
                                            </DataTemplate> 
        
                                        </telerik:GridViewDataColumn.CellEditTemplate> 
        
                                    </telerik:GridViewDataColumn>

and in code behind I have

    
            private void Editor_Loaded(object sender, RoutedEventArgs e)  
        
                    {  
        
                        Control ctrl = sender as Control;  
        
                        if (ctrl != null)  
        
                        {  
        
                            ctrl.Focus();  
        
                        }  
        
                    }

When I am in edit mode, I get a textbox. If I do tab the value is saved. If I click anywhere else, the value is not saved. Also, if I am in the last cell, hitting tab goes outside the control and value is not saved. I have to hit shift+tab to save the content. This dramatically alters the user's behaviour.

Is there a way to save the edited value on lost focus? I tried UpdateSourceTrigger=LostFocus too. No luck.

    
            <TextBox Text="{Binding ProcedureName, Mode=TwoWay, UpdateSourceTrigger=LostFocus}" MaxLength="20" Loaded="Editor_Loaded" />

Any help would be highly appreciated.

ModalBackground isn't working

WPF RadWindow (Q1 2010) is never showing a modal background.

Here is simple example xaml:

                    Window x:Class="Window1"         
                    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"         
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"         
                    xmlns:telerikNavigation="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"         
                    Title="Window1" Height="400" Width="600" WindowStartupLocation="CenterOwner">         
                <Grid>         
                    <telerikNavigation:RadWindow ModalBackground="Red"         
                                       Name="testObj" Height="100" Width="200" CanClose="True"         
                                       WindowStartupLocation="CenterOwner" Background="Beige"/>         
                </Grid>         
            </Window>         

Here is the code:

                    Class Window1          
                Public Sub x() Handles Me.MouseLeftButtonDown         
                    testObj.ShowDialog()         
                End Sub         
            End Class         

Image is attached.

Any idea what's up?

Thanks
