Hello

I'm using a details template for a row as follows:

    
            <DataTemplate x:Key="DiscussionDetailsTemplate"> 
        
                        <Grid> 
        
                            <Grid.ColumnDefinitions> 
        
                                <ColumnDefinition Width="Auto" /> 
        
                                <ColumnDefinition Width="*" /> 
        
                            </Grid.ColumnDefinitions> 
        
                            <Grid.RowDefinitions> 
        
                                <RowDefinition Height="Auto"/> 
        
                            </Grid.RowDefinitions> 
        
                            <TextBlock Grid.Row="0" Grid.Column="0" Text="Discussion Text: " Margin="12,0,0,0" FontSize="13" FontWeight="Bold" /> 
        
                            <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding mNotes}" TextWrapping="Wrap" FontSize="13" Margin="12,0,0,0" HorizontalAlignment="Left" /> 
        
                        </Grid> 
        
                    </DataTemplate>

Basically, the details template shows a potentially long message in a discussion. Here's the code for the grid using the template:

    
            <telerik:RadGridView Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="3" Name="DiscussionListGridView" Style="{DynamicResource DefaultGrid}"  
        
                                             ItemsSource="{Binding DiscussionList}" SelectedItem="{Binding SelectedDiscussion}" AutoGenerateColumns="False"  
        
                                             ScrollMode="RealTime" DataLoadMode="Synchronous" CanUserSortColumns="True"  
        
                                             RowDetailsVisibilityMode="VisibleWhenSelected" RowDetailsTemplate="{StaticResource DiscussionDetailsTemplate}" 
        
                                             > 
        
                            <telerik:RadGridView.Resources> 
        
                                <Style TargetType="telerik:RadGridView"> 
        
                                    <Setter Property="ShowGroupPanel" Value="False"/> 
        
                                </Style> 
        
                            </telerik:RadGridView.Resources> 
        
                            <telerik:RadGridView.Columns> 
        
                                <telerik:GridViewDataColumn Width="Auto" Header="From" Name="AuthorName" IsReadOnly="True" DataMemberPath="sgAuthorName"  
        
                                                            TextWrapping="Wrap"  /> 
        
                                <telerik:GridViewDataColumn Width="*" Header="Subject" Name="Subject" IsReadOnly="True" DataMemberPath="sgDescription"  
        
                                                            TextWrapping="Wrap" /> 
        
                                <telerik:GridViewDataColumn Width="Auto" DataFormatString="{}{0:dd/MM/yyyy}" Header="Date" Name="StatusDateDue"  
        
                                                            IsReadOnly="True" DataMemberPath="dtDateCreated" TextWrapping="Wrap"  /> 
        
                            </telerik:RadGridView.Columns> 
        
                        </telerik:RadGridView>

The problem that I'm having is that if the text is particularly long in the row details view, it won't wrap automatically. Instead it forces a scrollbar at the bottom of the grid and makes the user manually scoll - this isn't my desired behaviour.

Any tips on how to cause the text to wrap correctly?

Custom Hierarchy in GridView

Hi

I'm trying to get a custom hierarchy going in the new Q3 Gridview. The examples don't explain how to do this properly (the example under Custom Hierarchy is actually a Property Hierarchy).

Here's how I did it in the previous version:

    
                    public FailedMessagesView() 
        
                    { 
        
                        InitializeComponent(); 
        
                        FailedFaxGrid.TableDefinition.PreviewDataRecordCreate += FailedFaxTableDefinition_PreviewDataRowCreate; 
        
                    } 
        
                    private void FailedFaxTableDefinition_PreviewDataRowCreate(object sender, DataRecordCreateEventArgs e) 
        
                    { 
        
                        FailedMessagesViewModel fmVM = (FailedMessagesViewModel)DataContext; 
        
                        SuppliersEntity theSupplier = (SuppliersEntity)e.Data; 
        
                        ObservableCollection<MessagesCheckedEntity> theMessages = new ObservableCollection<MessagesCheckedEntity>( 
        
                            fmVM.FailedFaxes.Where(m => m.fkidSupplier == theSupplier.idSupplier).ToList()); 
        
                        if (theMessages.Count > 0) 
        
                        { 
        
                            e.IsExpandableRecord = true; 
        
                            GridViewTableDefinition ffDefs = new GridViewTableDefinition(); 
        
                            ffDefs.AutoGenerateFieldDescriptors = false; 
        
                            ffDefs.DataSource = theMessages; 
        
                            GridViewDataColumn checkBox = new GridViewDataColumn(); 
        
                            checkBox.Name = "FailedFaxCheckValName";

                            checkBox.IsGroupable = false; 
        
                            checkBox.IsReadOnly = true; 
        
                            checkBox.CellStyle = (Style)FailedFaxGrid.FindResource("checkValueStyle"); 
        
                            checkBox.Width = GridViewLength.Auto; 
        
                            ffDefs.FieldDescriptors.Add(checkBox); 
        
                            GridViewDataColumn JobNo = new GridViewDataColumn();

                            GridViewDataColumn TaskNotes = new GridViewDataColumn(); 
        
                            TaskNotes.Name = "TaskNotes"; 
        
                            TaskNotes.Header = "Task Notes"; 
        
                            TaskNotes.IsFilterable = false; 
        
                            TaskNotes.IsGroupable = false; 
        
                            TaskNotes.IsReadOnly = true; 
        
                            TaskNotes.DataMemberBinding = new Binding("DataRow[mNotes]"); 
        
                            TaskNotes.Width = new GridViewLength(1, GridViewLengthUnitType.Star); 
        
                            TaskNotes.TextWrapping = TextWrapping.Wrap; 
        
                            ffDefs.FieldDescriptors.Add(TaskNotes); 
        
                            GridViewDataColumn ReceiptDetails = new GridViewDataColumn(); 
        
                            ReceiptDetails.Name = "ReceiptDetails"; 
        
                            ReceiptDetails.Header = "Failure Reason"; 
        
                            ReceiptDetails.IsFilterable = false; 
        
                            ReceiptDetails.IsGroupable = false; 
        
                            ReceiptDetails.IsReadOnly = true; 
        
                            ReceiptDetails.DataMemberBinding = new Binding("sgReciptDetails"); 
        
                            ReceiptDetails.Width = new GridViewLength(1, GridViewLengthUnitType.Star); 
        
                            ReceiptDetails.TextWrapping = TextWrapping.Wrap; 
        
                            ffDefs.FieldDescriptors.Add(ReceiptDetails); 
        
                            e.ChildTableDefinitions.Add(ffDefs); 
        
                        } 
        
                    }

A warning pops up telling me that this method is obsolete, and doing it this way no longer works.

'SelfDrawingSeries' TargetType does not match type of element 'Line'.

I am trying to change the chart type used in the Grouping and Aggregation demo from a Bar to a Line and recieve the following error. 'SelfDrawingSeries' TargetType does not match type of element 'Line' when I try to run it.

The only change I have made to the example code is on this line:

    
            mapping1.SeriesDefinition = new BarSeriesDefinition(); 
        
            Changed to 
        
            mapping1.SeriesDefinition = new LineSeriesDefinition();

This also happens with the SplineSeries as well.

Am I missing something or is this a bug?

Thanks

Edit: I should have mentioned I am using the 10/23 Beta 2 build

autoscroll Grid when dragdrop

I have two grid's where I can dragdrop from "grid 1" to "grid2", I can drop and insert anywere in the grid (all works fine) but I can only drop in the rows I see.

I need the grid to scroll down if I try to drop at the bottom of the rows, and scroll up if I drop at the top row.

How do I code that in C# (I'm using "RadDragAndDropManager")

3 level Hierarchy gridview

i heard that you can do it with ChildTableDefinition

can someone show me how to do it?

i currently have 2 levels (parent->child)
i want to have 3 levels (parent->child->child of child)

custom GridViewCell visual tree at runtime

i tried using the GridViewColumn.CellTemplate but i can't change it at runtime,

what i want to do is on the RowLoaded event change the cell visual tree(ComboBox, CheckBox)
based on the type of the object in the Cell.Content

i want to be able to change it for each individual cell
not a whole row/Column

i know that somewhere inside the cell there is a:

{System.Windows.Controls.Border}
and inside of it there is

{Telerik.Windows.Controls.GridView.AlignmentContentPresenter}
and inside of it there is the CellTemplate
but i can't access it from c#

i also tried to put in the resources of the GridView, couple of DataTemplates for different types (int,brush,enum)
but it ignors the resources

TileView Drag Drop and Mouse Acceleration Problem

I setup a simple TileView test application (WPF 2009 Q3 Release). The tile item does not follow the mouse drag point, especially if mouse acceleration is enabled and the mouse is moved faster. It happens with multiple rows/columsn but seems most pronounced with a single column such as the code below: (screenshot attached) (grabbed first tile item header, moved mouse to bottom, then to top, ended up with blank area at top, mouse pointer at top, tile item 1/2 way up the list.)

Any ideas for fixing this?

    
            <Window x:Class="TileViewTest2.Window2" 
        
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        
                Title="Window2" Height="800" Width="200 " xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">  
        
                <Grid> 
        
                        <telerik:RadTileView MaxColumns="1" Height="auto" Name="radTileView1" Width="auto" MaximizeMode="Zero">  
        
                            <telerik:RadTileViewItem Height="auto" Name="radTileViewItem1" Width="auto"/>  
        
                            <telerik:RadTileViewItem Height="auto" Name="radTileViewItem2" Width="auto"/>  
        
                            <telerik:RadTileViewItem Height="auto" Name="radTileViewItem3" Width="auto"/>  
        
                            <telerik:RadTileViewItem Height="auto" Name="radTileViewItem4" Width="auto"/>

TileView in WPF UserControl hosted in Windows Form

Hello,

In testing your q3 beta of RadControls for WPF, I believe I have run into a bug with the new TileView control when using it in a WinForm. The TileView control displays properly, however the ability to drag and drop the individual tiles does not work. This functionality is present when the WPF UserControl containing the TileView is hosted in a WPF Application, however I cannot get it to work when hosting in a WinForm.

Is there something special that I need to do to get the Tileview to function properly in a Windows Form?

Thanks,

Ben
