In an earlier thread, Ivan wrote:

"You can create a new ControlTemplate for DataFormValidationSummary and set it through RadDataForm's ValidationSummaryStyle property. In this ControlTemplate you can set a new ItemTemplate to the ItemsControl placed in the summary. Please, use the latest internal build, if possible, as we have fixed a related issue there."

I'm trying to do this, but I'm only about half-way there.

I'm setting ValidationSummaryStyle on the RadDataForm:

<telerik:RadDataForm

...

ValidationSummaryStyle="{StaticResource validationSummaryStyle}"

/>

And in Resources I'm defining the style that sets DataFormValidationSummary.Template, and the ControlTemplate that it is being set to.

<UserControl.Resources>

<ControlTemplate x:Key="validationSummaryTemplate">

<Label>Foo</Label>

</ControlTemplate>

<Style TargetType="telerikDataForm:DataFormValidationSummary" x:Key="validationSummaryStyle">

<Setter Property="Template" Value="{StaticResource validationSummaryTemplate}" />

</Style>

</UserControl.Resources>

And this works, so far is it goes. I see the string "Foo" in the appropriate spot.

But I'm unclear as to what "set a new ItemTemplate to the ItemsControl placed in the summary" is supposed to mean.

Grid with Multiple Headers

Hi,

I have to design a grid which is having a multiple headers (Grey shaded part shown in the attached sample image). First header with a check box and second header is static just displays a value lika label and the Third header which shows total number of rows entered in the grid and the sum of the row values. Then the fourth header displays the column headers.

For the sample i have shown the three grids, it can be n number of grids dynamically added and all the grid rows are editable.

Can someone help me in this?

Docking LayoutStream Problem

HI,

i use a RadDocking- Control and add Panes by code:

RadPane radPane = new RadPane() { Title = panename_s, Name = name_s };

RadDocking.SetSerializationTag(radPane, panename_s);

RadPaneGroup radPaneGroup = new RadPaneGroup();

RadSplitContainer radSplitContainer = new RadSplitContainer() { InitialPosition = DockState.FloatingDockable };

Controls.LayoutData MyControl = new Controls.LayoutData();

MyControl.Name = name_s;

radPane.Content = MyControl;

radPaneGroup.Items.Add(radPane);

radSplitContainer.Items.Add(radPaneGroup);

Docking.Items.Add(radSplitContainer);

This works fine. Now add one (AAA) Pane and save this layout to a xml-file. A second pane will be created (BBB). Now i delete
the second pane (BBB) and save the layout again. How do i delete this second pane from the LayoutStream? In my void "Docking_Element"-Method this second pane is still shown!

Thanks
Best Regards
Rene

LoadLayout

Hi,

i tried you exmaple to load my laypout, but i geht this error-message:
"The path specified format is not supported."

string path_s = Klassen.helper.WPFAnwendung_Path() + "\\Layout\\laoyut.xml";

// Load your layot from the isolated storage.

using ( IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForAssembly() )

{

using (var isoStream = storage.OpenFile("E:\\WPF_Dev\\ITA-Reporting\\ITA-Reporting\\bin\\Debug\\Layout\\Layout.xml", FileMode.Open))

Save Layout with Controls??

Hi,

i add a RadPane dynamically by clicking a button.

{

RadPane radPane = new RadPane() { Content = new Controls.LayoutData() };

RadPaneGroup radPaneGroup = new RadPaneGroup();

RadSplitContainer radSplitContainer = new RadSplitContainer() { InitialPosition = DockState.FloatingDockable };

radPaneGroup.Items.Add(radPane);

radSplitContainer.Items.Add(radPaneGroup);

Docking.Items.Add(radSplitContainer);

}

As you can see the Content of the RadPane ist a Usercontrol called "Controls.LayoutData". In this Control i can choose a Report,
which is shown in the Control.

But how do i save this layout?

This way just save the Layout with empty RadPanes:

try

{

MemoryStream stream = new MemoryStream();

this.Docking.SaveLayout(stream);

stream.Seek(0, SeekOrigin.Begin);

StreamReader reader = new StreamReader(stream);

string xml_s = reader.ReadToEnd();

string path_s = Klassen.helper.WPFAnwendung_Path() + "/Layout/laoyut.xml";

using (StreamWriter Mywriter = new StreamWriter(@path_s))

{

Mywriter.Write(xml_s);

Mywriter.Close();

Mywriter.Dispose();

}

how do I save the contents of the newly created/all RadPanes????

Thanks a lot
Best Regards
Rene

Radpane MVVM floating issue

I have a radpane which can have different viewmodels as a datatemplate. I attached my object to the content of the radpane.
When the pane is docked there is not issue, but when the pane is in the floating state, the templated control only shows the datatype of the viewmodel.

 <telerik:RadPane x:Name="paneManufacturers" 
                  Header="{x:Static Properties:Resources.LabelLibraryExplorer}"
                  Content="{Binding AvailableItems}">
</telerik:RadPane>

WPF RadGridView containing RadDatePicker - How to change Style of date picker upon Trigger of GridViewRow IsSelected

Specifically i want to change the background color of the RadDatePicker (as well as the whole row) when i am changing the currently selected row with the up/down arrow keys.

To change the color of current row (highlighted) is achieved somewhat using Style.Triggers as per the following code:

<telerik:RadGridView Name="tlrkGridView"

IsFilteringAllowed="False" ShowGroupPanel="False" CanUserSortColumns="False" IsSynchronizedWithCurrentItem="True"

ItemsSource="{Binding Players}"

AutoGenerateColumns="False">

<telerik:RadGridView.RowStyle>

<Style TargetType="{x:Type telerik:GridViewRow}">

<Style.Triggers>

<Trigger Property="IsSelected" Value="True">

<Setter Property="Background" Value="AliceBlue"></Setter>

</Trigger>

</Style.Triggers>

</Style>

</telerik:RadGridView.RowStyle>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Number}"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Country}"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding StartDate}" DataFormatString="{} {0: d/MM/yyyy}" Header="Custom Header">

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<telerik:RadDatePicker x:Name="datePicker" DateTimeWatermarkContent="<Select a date>" SelectedValue="{Binding StartDate, Mode=OneWay}" />

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

<telerik:GridViewDataColumn.CellEditTemplate>

<DataTemplate>

<telerik:RadDatePicker x:Name="datePickerEdit" DateTimeWatermarkContent="<Select a date>" SelectedValue="{Binding StartDate, Mode=TwoWay}" />

</DataTemplate>

</telerik:GridViewDataColumn.CellEditTemplate>

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn DataMemberBinding="{Binding EndDate}" DataFormatString="{} {0: d/MM/yyyy}" />

<telerik:GridViewComboBoxColumn DataMemberBinding="{Binding ClubID}"

ItemsSource="{Binding Clubs, Source={StaticResource MyViewModel}}"

SelectedValueMemberPath="ID" >

<telerik:GridViewComboBoxColumn.ItemTemplate>

<DataTemplate>

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition />

<ColumnDefinition Width="*"></ColumnDefinition>

</Grid.ColumnDefinitions>

<TextBlock Text="{Binding ID}"/>

<TextBlock Text=" - " Grid.Column="1"/>

<TextBlock Text="{Binding Name}" Grid.Column="2"/>

</Grid>

</DataTemplate>

</telerik:GridViewComboBoxColumn.ItemTemplate>

</telerik:GridViewComboBoxColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

But HOW TO MAKE THE TRIGGER AFFECT/SET THE STYLE OF THE RadDatePicker which is contained within the RadGridView? Is it do-able in XAML ?

Basically i want to make the color of a selected row (the whole row) the same, regardless of whether it contains default column types, or other controls within a column. The GridViewComboBoxColumn behaves as expected, and EndDate field in my example behaves as expected. The reason i am using a RadDatePicker is because i want to show the Calendar icon in cell view mode.

Dynamic BarSeries

I need to be able to specify a dynamic set of BarSeries for a RadCartesianChart through XAML which is bound to a property in my viewmodel.

I tried creating a property which is of type List<CartesianSeries> and binding to that but it is not working.

public List<CartesianSeries> BarSeriesList

{

get

{

List<CartesianSeries> barSeriesList = new List<CartesianSeries>();

foreach (ChartDataPointModel dataPoint in DataPoints)

{

BarSeries barSeries = new BarSeries();

barSeries.DataPoints.Add(new CategoricalDataPoint() { Value = dataPoint.Value, Label = dataPoint.Name, Category = dataPoint.Name });

barSeriesList.Add(barSeries);

}

return barSeriesList;

}

set

{

// do nothing

}

The XAML I tried to use to bind to it is:

<chart:RadCartesianChart Palette="{Binding Palette}" Height="300" Width="500">

<chart:RadCartesianChart.Series>

<chartView:BarSeries ValueBinding="Value" CategoryBinding="Name" ItemsSource="{Binding BarSeriesList}" />

</chart:RadCartesianChart.Series>

<chart:RadCartesianChart.HorizontalAxis>

<chartView:CategoricalAxis/>

</chart:RadCartesianChart.HorizontalAxis>

<chart:RadCartesianChart.VerticalAxis>

<chartView:LinearAxis LabelFormat="0" />

</chart:RadCartesianChart.VerticalAxis>

<chart:RadCartesianChart.Grid>

<chartView:CartesianChartGrid MajorLinesVisibility="Y" />

</chart:RadCartesianChart.Grid>

</chart:RadCartesianChart>

How is the BarSeries supposed to be bound to make it dynamic?

Thanks,

Tracy
