Hi

I have been using the property grid and I like it a lot, but now i have problem. Is there a way to add "properties" at runtime?

I have been trying to get a datatable/datarow to work with the property grid with no luck.

Any ideas?

Map slow for zoom in/out

I am plotting about 500 items on the map and everything works fine until I zoom in or out. When this happens the CPU goes to 100% for 10 or so seconds and then things work again until the next zoom.

I used ANTS and found that all the slowness is from the method Telerik.Windows.Controls.Map.FileCacheBase.SaveFilesThread().

I also noticed this xaml error which is not from me:

System.Windows.Data Error: 25 : Both 'ContentTemplate' and 'ContentTemplateSelector' are set; 'ContentTemplateSelector' will be ignored. ContentPresenter:'ContentPresenter' (Name='')

ToolTip not displayed inside Popup

Hi,

Using version 2012.1.326.40 of the DataVisualization control, the ToolTip is not displayed when the RadTimeline is inside a Popup. Mouse hovering over individual items works. Any ideas?

The code below illustrates my symptoms.

<Window x:Class="WpfApplication3.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

xmlns:example="clr-namespace:WpfApplication3"

Title="MainWindow" Height="350" Width="525">

<Window.DataContext>

<example:ExampleViewModel />

</Window.DataContext>

<Grid>

<Popup IsOpen="True" Width="800" Height="300">

<telerik:RadTimeline Grid.Row="0"

PeriodStart="{Binding StartDate, Mode=TwoWay}"

PeriodEnd="{Binding EndDate, Mode=TwoWay}"

VisiblePeriodStart="{Binding VisibleStartDate, Mode=TwoWay}"

VisiblePeriodEnd="{Binding VisibleEndDate, Mode=TwoWay}"

StartPath="StartDate"

DurationPath="Duration"

ToolTipPath="Details"

ItemsSource="{Binding Data}">

<telerik:RadTimeline.Intervals>

<telerik:DayInterval />

<telerik:YearInterval IntervalSpans="1,5" />

<telerik:MonthInterval IntervalSpans="1,6" />

</telerik:RadTimeline.Intervals>

</telerik:RadTimeline>

</Popup>

</Grid>

</Window>

Scrolling not working on tileview

I'm using a tileview to show a list of images with the ability to reorder and delete images as needed. The image of what it looks like is attached.

Currently, when I delete an image (which I do by removing an item from the collection) it sets the viewer all the way back to the left and there is no way to programmatically(c#) scroll back to the right where the image was deleted from.

So what I need to understand is how do I set the scroll position of the radtileview?

Here's my view code.

<telerik:RadTileView x:Name="ListView1" MaxRows="1" MaximizeMode="Zero" ScrollBarVisibility="Visible" ColumnWidth="Auto" Height="210"

TileDragEnded="RadTileView1_TileDragEnded" ItemContainerStyle="{DynamicResource RadTileViewItemStyle}"

HorizontalContentAlignment="Left"

SelectionChanged="ListView1_SelectionChanged" IsItemDraggingEnabled="True"

IsSelectionEnabled="True" IsAutoScrollingEnabled="True">

<telerik:RadTileView.ContentTemplate >

<DataTemplate >

<Grid Margin="10,0,10,0" HorizontalAlignment="Left" >

<Border BorderThickness="1" Margin="-2" Background="Transparent" BorderBrush="Black" HorizontalAlignment="Left" VerticalAlignment="Top" >

<Border.Effect>

<DropShadowEffect ShadowDepth="0" BlurRadius="10"></DropShadowEffect>

</Border.Effect>

<Image Height="Auto" Width="Auto" VerticalAlignment="Top" Source="{Binding ThumbnailImageControl}" />

</Border>

</Grid>

</DataTemplate>

</telerik:RadTileView.ContentTemplate>

</telerik:RadTileView>

Here's the style referenced:

<Style x:Key="RadTileViewItemStyle" TargetType="{x:Type telerik:RadTileViewItem}" >

<Setter Property="Template" >

<Setter.Value>

<ControlTemplate TargetType="{x:Type telerik:RadTileViewItem}" >

<Border x:Name="GripBarElement" Background="Transparent" Width="Auto" HorizontalAlignment="Left" VerticalAlignment="Top">

<Grid Margin="5" HorizontalAlignment="Left" VerticalAlignment="Top" Width="Auto" >

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

<RowDefinition Height="*" />

</Grid.RowDefinitions>

<ContentPresenter x:Name="ContentElement" MouseDown="img_MouseDown"

Grid.Row="1" Width="Auto" HorizontalAlignment="Left" VerticalAlignment="Top"

Content="{TemplateBinding Content}"

ContentTemplate="{TemplateBinding ContentTemplate}" />

<Grid x:Name="ContentCacheHost" Grid.Row="0" Width="Auto" HorizontalAlignment="Left" VerticalAlignment="Top" />

<Grid MinHeight="23" Grid.Row="0">

<Button Content="X" Height="23" Margin="0,0,0,0"

Width="23" Click="btnDelete_Click"

Name="btnDelete"

Tag="{Binding FilePath}" MouseEnter="btnDelete_MouseEnter" MouseLeave="btnDelete_MouseLeave"

Foreground="White" FontSize="14" FontWeight="Bold" Opacity=".4"

VerticalAlignment="Top" HorizontalAlignment="Left" >

<Button.Background>

<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">

<GradientStop Color="#00AF69" Offset="0" />

<GradientStop Color="#138D5D" Offset="1" />

</LinearGradientBrush>

</Button.Background>

</Button>

</Grid>

</Border>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

Here's how I bind:

public ObservableCollection<StaticObjects.BmpImage

> BitmapImageList { get; set; }



ListView1.ItemsSource = BitmapImageList;

I thought this would work but no luck

if (currentselectedindex > 0)

{

ListView1.SelectedIndex = currentselectedindex - 1;

ListView1.BringIntoView(ListView1.Items[currentselectedindex]);

}

Here's another clue in the delete any ideas?

void btnDelete_Click(object sender, RoutedEventArgs e)

{

Button btn = (Button)sender;

string filepath = btn.Tag.ToString();

StaticObjects.BmpImage bmp = BitmapImageList.Where(p => p.FilePath == btn.Tag).SingleOrDefault();

int currentidex = ListView1.Items.IndexOf(bmp);

bmp.Dispose();

BitmapImageList.Remove(bmp);

}

Lots of points?

It looks like your demos all have a handful of points...do you support x-y graphs with thousands of points, like scientific data?

Iterate Throught TreeView Items

Hi,

I'm trying to follow this example: http://www.telerik.com/help/wpf/radtreeview-how-to-iterate-through-treeviewitems.html .Apparently it allows me to iterate through a RadTreeView.

However, I get the following error:
Error 8 The type or namespace name 'ItemsControl' does not exist in the namespace 'Telerik.Windows.Controls' (are you missing an assembly reference?)

RadGridView / UI Automation

Hi,
I do manage to execute a number of action with UI Automation against a radGridView such as:
- Creating a new row
- Reading the content of a cell
But I really don't understand how one could write in a cell. Using Snoop, I can see that before you select a cell, its underlying control is a TextBlock and only when you click on the cell, you get a TextBox. Which automation patterns do you use to click on a given cell?
My goal is to simulate a click on the cell, the get access to the underlying TextBox in order to change its content.
Please let me know if this can be done.

Thank you in advance,
Hassan
