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")

[Solved] 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"/>  
        
                            <telerik:RadTileViewItem Height="auto" Name="radTileViewItem5" Width="auto"/>  
        
                        </telerik:RadTileView> 
        
                </Grid>

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

Comparison between telerik and MS WPF control

It would be nice to have a comparison between a telerik control and the Microsoft native equivalent if it exists.

It's easier to point management to a web page that illustrates why the telerik control is a better alternative to the built-in control. It would help sell a lot more copies :-)

Thanks,
Ash

[Solved] Gridview Styling issues

I've searched through the forum and documentation but can't seem to find an answer to these styling issues.

1. How to style the header cell background when a column is sorted or the header cell is hovered.

2. How to style the foreground of a selected row

3. How to style the 'column freeze' bar

4. How to style the Horizontal and Vertical Scroll Bars

5. How to style the column filter indicator.

Any tips on these would be very appreciated.

[Solved] Simple Combobox column - clearly I am missing the obvious...

Hey all!

Now, clearly this is my problem and not one with the grid however I am just not seeing how I am going wrong. Given the following XAML...

    
                    <telerik:RadGridView Name="radGridView1" AutoGenerateColumns="False" UseAlternateRowStyle="True">  
        
                        <telerik:RadGridView.Columns> 
        
                            <telerik:GridViewComboBoxColumn UniqueName="Active" DataMemberBinding="{Binding IsActive}" SelectedValueMemberPath="Value" DisplayMemberPath="Title" /> 
        
                            <telerik:GridViewDataColumn UniqueName="User" DataMemberBinding="{Binding Name}" /> 
        
                        </telerik:RadGridView.Columns> 
        
                    </telerik:RadGridView>

And the following code to fill it...

    
                    public Window1()  
        
                    {  
        
                        InitializeComponent();  
        
                        var activeflaglist = new List<ActiveFlag>();  
        
                        activeflaglist.Add( new ActiveFlag{ Title = "Yes", Value = "Y" } );  
        
                        activeflaglist.Add( new ActiveFlag{ Title = "No", Value = "N" } );  
        
                        var userlist = new List<User>();  
        
                        userlist.Add( new User{ IsActive = "Y", Name = "Bob StartsActive" } );  
        
                        userlist.Add( new User{ IsActive = "N", Name = "Fred StartsInActive" } );  
        
                        userlist.Add( new User{ IsActive = "Y", Name = "John StartsActive" } );  
        
                        userlist.Add( new User{ IsActive = "Y", Name = "Alice StartsActive" } );  
        
                        userlist.Add( new User{ IsActive = "N", Name = "Janet StartsInActive" } );  
        
                        var activeColumn = (GridViewComboBoxColumn)radGridView1.Columns["Active"];  
        
                        activeColumn.ItemsSource = activeflaglist;  
        
                        radGridView1.ItemsSource = userlist;  
        
                    }

If you build the project (the link is below) and then try to use the combo box a crash is instant. What a I missing?
