hello,

i'm having a problem collapsing a details grid from within the details grid. the master grid has a GridViewToggleRowDetailsColumn to display details and close them. the problem is, there is a button in the details grid (of type RowDetailsTemplate) which does some operation and afterwards should close the details automatically. i'm using event LoadingRowDetails so using a HierarchyChildTemplate is a problem.
how can i collapse the details grid with the button inside?

since the documention is very poor on wpf controls i'm having difficulties figuring out which property and which method does what. examples (how to's) are really appreciated.

thanks,

GridView

[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?
