Hello All,

I have RadGridView which hava a button embeded. The button is binded with a command and the command parameter is the content of each row. The bind expression of CommandParameter is "{Binding Path=Content, RelativeSource={RelativeSource TemplatedParent}}". The problem is the command cannot get its parameter. I am sure the command binding is works, because it is working well if I using a DataGrid insteast. Does anyone could help me.

Thank you && Best Regards
Wei

Load image make change and save back to database

Hi

I'm not sure if WPF is the right technology or which Telerik control is best suited for the following scenario, so I would appreciate any recommendations that anyone can give me.

Secnario:

The user will load images from a database that were captured on camera.
The user will need to view at least 4 images at a time and maybe click one to view in full screen.(carousel control?).
The user should be able to draw circle on the image to highlight certain parts of the image. This image must then be saved back to the database as a copy of the original with the users changes/highlights.

Can this be done in WPF with Telerik controls or can it be done easier with a different technology.

Thanks
Paul

CandlestickSeries and negative Values

Hi Telerik Team.

The CandlestickSeries seems to have an odd behavior for negative values. The attached image shows a graph where the candlestick values should decrease linearly from left to right, but they stop at around y=0.

What is a workaround for this?

I use Telerik Version 2012.2.912.40, WPF

Code:

<telerik:RadCartesianChart>

<telerik:RadCartesianChart.VerticalAxis>

<telerik:LinearAxis/>

</telerik:RadCartesianChart.VerticalAxis>

<telerik:RadCartesianChart.HorizontalAxis>

<telerik:CategoricalAxis/>

</telerik:RadCartesianChart.HorizontalAxis>

<telerik:CandlestickSeries x:Name="Series0"

HighBinding="High"

OpenBinding="Open"

CloseBinding="Close"

LowBinding="Low"

CategoryBinding="X">

</telerik:CandlestickSeries>

</telerik:RadCartesianChart>

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

this.Loaded += new RoutedEventHandler(MainWindow_Loaded);

}

void MainWindow_Loaded(object sender, RoutedEventArgs e)

{

var chartData = new List<MyChartDataClass>();

for (int i = 0; i < 35; i++)

{

var cdc = new MyChartDataClass()

{

X = i,

High = 5 - i,

Open = 4 - i,

Close = 3 - i,

Low = 2 - i,

};

chartData.Add(cdc);

}

Series0.ItemsSource = chartData;

}

public class MyChartDataClass

{

public int X { get; set; }

public double Close { get; set; }

public double Low { get; set; }

public double Open { get; set; }

public double High { get; set; }

}

I would like to open, focus and select all text in editable RadComboBox when my wpf form is opened.

So I set following properties:

OpenDropDownOnFocus="True" SelectAllTextEvent="GotFocus"

and I call the Focus(); on form's constructor.

But the comboBox is closed with no selected text in it.

Could you help me what am I doing wrong?

Thank you for your replies.

Setting Pan and Scale

Using your pdfviewer control.
If I set IsInPanMode = "true" on the contol it doesn't seem to honor that setting. However if i have a toggle button that i bind to the FixedDocumentViewer.IsInPanMode property it seems to work.

I get the same effect with ScaleMode - except here : if i set it directly on the control it doesn't work, but I also can't seem to get FixedDocumentViewer.ScaleFactor binding to work on other controls like Slider etc.

Any hints at what I'm doing wrong?

Radribboncombobox - Type of the selected item is displayed instead of value in 2013.1.220.1050

When a list is bound to RadComboxBox, the selected item is showing the type instead of actual value.

<Controls:RadRibbonComboBox x:Name="namesCombo">

<Controls:RadRibbonComboBox.ItemTemplate>

<DataTemplate>

<Border Background="Transparent">

<TextBlock Text="{Binding Name}">

<UserControls:TooltipHelper.Tooltip>

<ToolTip Template="{StaticResource TextToolTipTemplate}" Content="{Binding Description}"/>

</UserControls:TooltipHelper.Tooltip>

</TextBlock>

</Border>

</DataTemplate>

</Controls:RadRibbonComboBox.ItemTemplate>

</Controls:RadRibbonComboBox>

private void SetWriteableTemplates(bool isUserAdmin)

{

if (Templates == null) return;

namesCombo.ItemsSource = Templates.Where(t => isUserAdmin || !t.IsSystem).ToList();

namesCombo.SelectedIndex = 0;

}

But the selected item will be the type of the list instead of actual value.

The value for Name wont be displayed in selected value.
for eg : The Name property contains certain values and its type is observable collection. Then the selected value will be displayed as that observablecollection
