Hi,

First of all let me tell you that We are using Q1 2009 Telerik controls.

I have a Time Picker in my window,Its showing proper 12 hour format when i select from time from Time Picker, Now When i say like radTimePicker.SelectedTime=new TimeSpan(23,05,00) it showing 24 hour format..

Another thing, its working fine with "Page" but not with window and usercontrol.

Thanks,
Ravi Lakhani

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         
                    }

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?

TreeViewItem lacks a Command property.. is there a way to do this?

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

Custom args to WindowClosedEventArgs

When I use the WindowClosedEventArgs I need to be able to pass my own variable all the way through so i can use the variable on close. Can we get an "arg" parameter or something to do this? ATM it looks like i'll have to make a bunch of member variables to hold the state.
