Can't insert text between two PermissionRanges?

Hi

Not sure if I'm being thick here, but I can't figure this out after hours of trying.

If I have two Permission Ranges (I assume it applies to most other annotations, but this is what I've been using).

They appear on the page like this, separated by a carriage return:

[Range 1]
[Range 2]

If I set the Document Position inside Range 1, and use "MoveToNext()", it moves straight from one span into the next. I'm trying to insert something in-between the two, and I'm finding it impossible for the Document.Insert() not to end up inside one of the PermissionRanges!

Any pointers appreciated!

[Solved] CheckBoxColumn not showing correct state when AutoGenerateColumns="False"

I have a RadGrid with a CheckBoxColumn and AutoGenerateColumns="False". When I check a checkbox in the CheckBoxColumn and press Tab, the CheckBox shows the unchecked state. When I next press Shift-Tab to place focus back in the cell, the CheckBox shows the checked state.

Very simple code:

<telerik:RadGridView

ItemsSource="{Binding MyCv}"

AutoGenerateColumns="False">

<telerik:RadGridView.Columns>

<telerik:GridViewCheckBoxColumn

DataMemberBinding="{Binding MyBool}"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

If I use autogenerated columns, the checkbox always shows the correct state. Am I doing something wrong or is this a bug?

I'm using the 2012 Q1 version

[Solved] RadButtonGroup that is always accessible

Hi,

I have a requirement that I have a group of buttons that are always available (e.g. Help, Messaging, Refresh) and I'm looking for the best way to do this. A couple of thoughts I had were:

1) Have a button group with the horizontal alignment set to right on each of my tabs.
-It seems that I can't mix button groups with Left and Right HorizontalAlignment.
2) Have a second RadRibbonView with no application button in the top right corner with the static button group.
The second RadRibbonView doesn't display. If I use RadRibbonBar, I can get it do display, but it doesn't align with the other RadRibbonBar.
3) Create my own xaml to mimic the RadRibbonView
-Won't look quite right, and will be more work.

Can you tell me the best way to accomplish what I'm trying to do?

Thanks in advance,
Wyatt

[Solved] Can't resize the Marker

Hi!

I'm using Linear Gauge in my full screen project, for example, it looks like this:

<telerik:RadVerticalLinearGauge x:Name="linearGauge" Width="100" Height="300">

<telerik:LinearScale x:Name="linearScale" Min="1" Max="12" >

<telerik:LinearScale.Indicators>

<telerik:Marker x:Name="indicator" Value="5"/>

</telerik:LinearScale.Indicators>

</telerik:LinearScale>

</telerik:RadVerticalLinearGauge>

I've understand how to scale the gauge, but I can't scale the marker. Method with changing RelativeHeight value I've found in help does'n work - the error is "The property 'RelativeHeight' was not found in type 'Marker'". Styling doesn't work either. Please help!

Thanks!

[Solved] Exception when binding to ListCollectionView with filter

If I bind a RadGridView to a ListCollectionView with a filter, and I chance a value in a Grid cell that causes the filter to return false for that row, I get an exception in the Grid cell.

Code to reproduce:

public class MyEntity : INotifyPropertyChanged

{

private bool _myBool;

public bool MyBool

{

get { return _myBool; }

set

{

_myBool = value;

PropertyChanged(this, new PropertyChangedEventArgs("MyBool"));

}

public event PropertyChangedEventHandler PropertyChanged;

}

public partial class MainWindow

{

public MainWindow()

{

InitializeComponent();

DataContext = this;

MyEntities = new ObservableCollection<MyEntity> { new MyEntity(), new MyEntity(), new MyEntity() };

MyCv = (ListCollectionView)CollectionViewSource.GetDefaultView(MyEntities);

MyCv.Filter = MyBoolFilter;

}

public ObservableCollection<MyEntity> MyEntities { get; set; }

public ListCollectionView MyCv { get; set; }

private bool MyBoolFilter(object item)

{

return !((MyEntity)item).MyBool;

}

<Window x:Class="GridViewTest.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

Title="MainWindow" Height="350" Width="525">

<telerik:RadGridView ItemsSource="{Binding MyCv}"/>

</Window>

Steps to reproduce:
1. check one of the checkboxes in the grid
2. move focus to somewhere else

I use version Q3 2011 SP1, .Net 4.0

Is there a way around this problem?

Drag Tile without clicking the header

Hi,

Is possible to drag tile item without clicking the header? I need to drag the tile by clicking in the tile, and moving around holding the mouse button. The idea is to use this in a touch screen and I want the user clicking in the tile instead of the header. How can I do that?

Best regards,
Gonçalo Martins
