Hi,

I initialize dragging by following code:

DragDropManager.AddDragInitializeHandler(xToolBar1, OnDragInitialize);

DragDropManager.AddGiveFeedbackHandler(xToolBar1, OnGiveFeedback);

In GiveFeedbackHandler and DropHandler Mouse.GetPosition(xToolbarTray) gives negative numbers, which is incorrect. Is this bug?
I attached sample project to demonstrate this behaviour: https://skydrive.live.com/redir?resid=51A46BBA4E9EF07E!1312&authkey=!ALflFx7eswlzjic

Basically, I need distinguish between dragging or dropping on/before/after element in drop target.

I'm using reorder behaviour very often and just inserting element after the element under mouse gives very negative user experience. I cannot move element on the first position this way.

Global override for ScrollBar style on RadControls

I have an application where multiple RadGridViews are being used as well as a RadTreeView. I would like to override the ScrollBar style for all RadControls in the application so that it uses the default Windows ScrollBar style instead of the RadControls own "shiny" version as it creates an inconsistent UI when other normal WPF ScrollViewers are used in the application. Here's an example: http://i.imgur.com/EXCRbey.png (the top is the default Windows 8 ScrollBar, bottom is a RadGridView ScrollBar).

I've tried adding the following in the application's ResourceDictionary, but it didn't work:

    <Style TargetType="ScrollBar" BasedOn="{StaticResource {x:Type ScrollBar}}"/>

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.

Just trying to figure out if the RadRichTextBox has a shortcut key for assigning bullets? The standard Ctrl + Shift + L does not work.

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}"/>
