How to use RadGridView-GridViewDataColumn.BindingGroup

hi:
I have a question when use GridViewDataColumn.BindingGroup,my core code as follow:

<telerik:GridViewDataColumn Header="Time" IsReadOnly="True" SortMemberPath="ScheduledProcedureStepStartDateTime">
                        <telerik:GridViewDataColumn.BindingGroup>
                            <MultiBinding Converter="{StaticResource timeRangeConverter}" ConverterParameter="HH:mm">
                                <Binding Path="StartDateTime"></Binding>
                                <Binding Path="EndDateTime"></Binding>
                            </MultiBinding>
                      </telerik:GridViewDataColumn.BindingGroup>
</telerik:GridViewDataColumn>

Please confirm syntax of binding is right?

When execute
public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture){} function,
I found values[0] and values[1] are DependencyProperty.UnsetValue. So can't convert successfully.

Please provide the right telerik demo. Tahnks.

CurrentCell and CurrentRow not in sync

It seems that the CurrentCell and CurrentRow are not kept in sync.

I think this is similar to what's mentioned in this post:
http://www.telerik.com/community/forums/wpf/gridview/radgridview-observablecollection-and-currentitem.aspx

We fixed it with this code:

private void ContractProxyGridView_CurrentCellChanged(object sender, GridViewCurrentCellChangedEventArgs e)

{

if (e.NewCell == null || e.NewCell.ParentRow == null) return;

e.NewCell.ParentRow.IsCurrent = true;

}

Is there a reason for this behavior?

Thanks,
Alex

CellEditTemplate binding

Hi

I have a question on using the CellEditTemplate which has a TextBox in RadGridView.

I have a RadGridView, one of its columns is created like this in cs file:

gvColumn = new GridViewDataColumn();
gvColumn.CellEditTemplate = (DataTemplate)grid.TryFindResource("TextBoxEditTemplate");
gvColumn.DataType = typeof(string);
gvColumn.DataMemberBinding = new Binding(...)

In xaml file I define the template like this:

<telerik:RadGridView.Resources>
                <DataTemplate x:Key="TextBoxEditTemplate">
                    <TextBox Text="{Binding RelativeSource={RelativeSource Self}, Path=DataMemberBinding.PropertyPath}"/>
                </DataTemplate>
...

but the 'Text' of this text box is not bound to content of the cell, they are sperated, when user tries to edit, the cell's content is not
in the TextBox, and vice versa.

Thanks.

Excel doesn't open when data contains HTML tags

Hi guys,

I noticed that when using ExportFormat.ExcelML with columns containg tags, the generated file cannot be opened. I have a column which contains "<" and ">" and this basically breaks the format. I tried intercepting the value in the ElementExporting event but it doesn't look like it's helping me. A sample event log file froom Excel looks like this:

XML PARSE ERROR: Missing end-tag
Error occurs at or below this element stack:
    <ss:Workbook>
     <ss:Worksheet>
      <ss:Table>
       <ss:Row>
        <ss:Cell>
         <ss:Data>
          <ss:CompanyName>

The value for column CompanyName would be something like "<Acme Inc>"

How do I go about this? I

RadDocking with PRISM 4 + MVVM + MefBootstrapper

I'm using the RegionAdapter from the following article.

http://blogs.telerik.com/blogs/posts/09-08-31/using_the_raddocking_control_with_prism.aspx

However, I'm using PRISM 4 + MVVM + MefBootstrapper.
Has anybody successfully used the RegionAdapter with MefBootstrapper?

I'm getting the following error message...

this

.Container.Resolve

Error 1 'System.ComponentModel.Composition.Hosting.CompositionContainer' does not contain a definition for 'Resolve' and the best extension method overload 'Microsoft.Practices.Unity.UnityContainerExtensions.Resolve<T>(Microsoft.Practices.Unity.IUnityContainer, params Microsoft.Practices.Unity.ResolverOverride[])'

Thank you

protected override RegionAdapterMappings ConfigureRegionAdapterMappings()

{

var mappings = base.ConfigureRegionAdapterMappings();

mappings.RegisterMapping(typeof(RadPaneGroup), this.Container.Resolve<RadPaneGroupRegionAdapter>());

return mappings;

}

IsExpandable Is not hiding the Expand Button

I'm having issues with getting the IsExpandable property to be respected. Basically when my "Parent" has no children, I don't want the expand togglebutton to be shown. Below is some sample xaml that I am using. The resulting grid has the details column fully populated with the togglebuttons when there should be at least one without the button. I've stepped through my StyleSelector code and it is returning the proper style. But it doesn't appear to have any affect. What am I doing wrong?

<UserControl ...>

<UserControl.Resources>

<Style x:Key="NoChildrenRowStyle" TargetType="telerik:GridViewRow">

<Setter Property="IsExpandable" Value="False"/>

</Style>

<Style x:Key="HasChildrenRowStyle" TargetType="telerik:GridViewRow">

<Setter Property="IsExpandable" Value="True"/>

</Style>

</UserControl.Resources>

<local:RowStyleSelector x:Key="RowStyleSelector"

NoChildrenStyle="{StaticResource NoChildrenRowStyle}"

HasChildrenStyle="{StaticResource HasChildrenRowStyle}"/>

<telerik:RadGridView ItemsSource="{Binding ParentsCollectionView}"

RowIndicatorVisibility="Collapsed"

AutoGenerateColumns="False"

RowStyleSelector="{StaticResource RowStyleSelector}">

<telerik:RadGridView.Columns>

<telerik:GridViewToggleRowDetailsColumn />

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

<telerik:GridViewDataColumn Header="Age" DatatMemberBinding="{Binding Age}"/>

</telerik:RadGridView.Columns>

<telerik:RadGridView.RowDetailsTemplate>

<DataTemplate>

<ListBox ItemsSource="{Binding Children}">

<ListBox.ItemTemplate>

<DataTemplate>

<Grid>

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

</Grid>

</DataTemplate>

</ListBox.ItemTemplate>

</ListBox>

</DataTemplate>

</telerik:RadGridView.RowDetailsTemplate>

</telerik:RadGridView>

</UserControl>

RoutingService readonly?!

In XAML, I try to bind the RoutingService of my diagram:

<telerik:RadDiagram ....... RoutingService="{Binding Router}" ... />

And I get this error:

'RoutingService' property is read-only and cannot be set from markup. Line 92 Position 45.

Why do I have to assign this router in code-behind? Makes sense to bind it since it can easily be a property of my viewmodel...

UPDATE: Basically, I'm trying to assign the Router to an instance of OrgTreeRouter.

RadControls for WPF Q3 2012

Hi!
I recently installed "RadControls for WPF Q3 2012" and I see only WPF40 and WPF45 in the binaries folder. What about WPF35 that existed in the previous release? Not available? What does this mean for my projects?
