I am prototyping a Windows WPF application using Windows 7's built-in multitouch gestures. I'd like to use telerik controls but before making the purchase I'd like to know if using the c# source will allow for me to capture gesture messages?

[Solved] Indicator on the linear gauge doesn't pick the IndicatorBackground colour.

I have the following code:



<

Gauges:RangeList>

<Gauges:RadialRange Min="0" Max="50"

StartWidth="0.02" EndWidth="0.03"

Location="Inside"

Background="#7F579132"

BorderBrush="{x:Null}"

IndicatorBackground="#FF4AB408" Offset="-0.07"/>

<Gauges:RadialRange Min="50" Max="75"

StartWidth="0.03" EndWidth="0.04"

Location="Inside"

Background="#7F9FAB32"

BorderBrush="{x:Null}"

IndicatorBackground="#FFF7E40D" Offset="-0.07"/>

<Gauges:RadialRange Min="75" Max="100"

StartWidth="0.04" EndWidth="0.05"

Location="Inside"

Background="#7F973C3C"

BorderBrush="{x:Null}"

IndicatorBackground="Red" Offset="-0.07" LabelForeground="{x:Null}"/>

</Gauges:RangeList>

<Gauges:IndicatorList Height="247" Width="247">

<Gauges:StateIndicator Left="0.8" Value="{TemplateBinding Value}" UseRangeColor="True"

/>



And the State Indicator shows the colour of the range rather than IndicatorBackground.

What is the reason for that?

RadGridView with colorpicker?

Hello Telerik Team,
                                   I have a doupt in radcolorpicker with radgridview.
We are fan of telerik controls.
         In my last project our master page contains 5 fields including radcolorpicker.our aim is the row details are shown in radgridview with diffrent color.The color value is user gives when adding each  entries.

     Here i am binding in XAML below:-

<Label Content="Color" Height="24" Margin="5,8,191,0" Name="label24" FontSize="11" Grid.Column="1" Grid.Row="3" VerticalAlignment="Top" />

<telerik:RadColorPicker SelectedColor=

"{Binding Path=Colour,Mode=TwoWay, UpdateSourceTrigger=LostFocus, NotifyOnValidationError=True, ValidatesOnDataErrors=True, ValidatesOnExceptions=True}"

Height="24" Margin="124,8,0,0" Name="rclrColour" TabIndex="24" FontSize="11" Grid.Column="1" Grid.Row="3" Width="39" />

The color value is stored in database as hexadecimal value.

i am using RowLoaded event for display color details.

private void rgrdCompanyViewAll_RowLoaded(object sender, Telerik.Windows.Controls.GridView.RowLoadedEventArgs e)

{

var row = e.Row as GridViewRow;

if (row != null)

{

var cell = ((CompanyBO)e.Row.Item).Colour;

if (cell != null)

{

var value = cell;

e.Row.Background = new SolidColorBrush((Color)ColorConverter.ConvertFromString(value.ToString()));

}

Here is my QUESTION:-
Every thing is fine.But the colors display in radgridview are changed each and every minute when i am using scroll bar(vertical).

i make mistake at anywhere?

Pls suggest me?

Re-use RadTreeListView DragCue

Hi there,

I have implemented Drag and Drop using RadDragAndDropManager. And in order to make the DragCue consistent with RadTreeListView, I would like to re-use RadTreeListView's DragCue since I use Drag and Drop capability in RadTreeListView.

so, how can I achieve that?
So far I've done this:

ContentControl dragCue = RadDragAndDropManager.GenerateVisualCue();

dragCue.Content = draggedItem.DataContext;

dragCue.ContentTemplate = this.Resources["DragCueTemplate"] as DataTemplate;

e.Options.DragCue = dragCue;

But, the appearance is still different with RadTreeListView.

Thanks and best regards,

Arinto

Can not undo changes after cancel edit

Hi,

after invoke command from button:

<telerik:RadButton Content="Cancel"

Command="telerik:RadGridViewCommands.CancelRowEdit"

CommandTarget="{Binding ElementName=nameOfRGV}" />

edit mode is canceled but values in cells are not undoing...
I use ActionAfterLostFocus="None" attribute on my gridview and in RowEditEnded event dictiorany OldValues is empty...
How can i force gridview to load old data?

I use List<MyClass> as ItemsSource for gargridview instead of ObservableCollection<MyClass>. Can it cause the problem?

I think that my source list is updated after each cell editing. I thought that source will be updated after commitedit event...

AdornerLayer Not Found

Hello,

I’m having a issue with RadGridView for WPF.

When dragging a column header into the grouping bar, It throws the following exception:

System.InvalidOperationException was unhandled.

Message=Root AdornerLayer Not Found. Please make sure that your root visual is Window or other element that has an adorner layer. Alternatively, wrap your root panel in an <AdornerDecorator> element.

I have tried to wrap the root panel (and any other panel) into an AdornerDecorator in xaml code. Alternatively, I tried to create an AdornerLayer by code and wrap the panel/s in AdornerDecorators but the result was always the same.

I’m using RadGridView in a custom control derived from Control class. It applies a generic template defined at generic.xaml file and this control is part of an independent assembly referenced in a main project.

Thank you very much for your help.

treeviewitem not expanding when new item dropped on

I have a list box that drops an item onto a treeView. The TreeView is bound to a List<> and has a two level template. The Item is dropped on the top level items and need the item to expand when the new item is dropped on it.

private void OnDropInfo(object sender, DragDropEventArgs e)

{

if (e.Options.Status == DragStatus.DropComplete)

{

ListBoxItem item = e.Options.Source as ListBoxItem;

DeviceApp payload = item.Content as DeviceApp;

freeApps.Remove(payload);

appList.UnselectAll();

appList.ItemsSource = freeApps;

stationTree.ItemsSource = stations;

appList.Items.Refresh();

stationTree.Items.Refresh();

}

The listBox is the source and i have added some clunky Refresh() to get both ItemsSources to update and show the changes. I know i am doing this wrong, but the tree branch still does not expand on drop.

Any help would be great!
Thanks,
Brian
