Upgrade to 2015.1.225.45 missing references

I just updated to version 2015.1.225.45 and now I get these error messages:

The type reference cannot find a public type named 'PickerTextBox'. Line 2096 Position 74. D:\Source\WPFPartsCatalogUpload\WPFPartsCatalogUpload\Themes\Telerik.Windows.Controls.xaml

The name "RadRangeControl" does not exist in the namespace "clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls". D:\Source\WPFPartsCatalogUpload\WPFPartsCatalogUpload\Themes\Telerik.Windows.Controls.xaml

I don't use either of these controls in my application. The errors are showing up in the dll's XML; Telerik.Windows.Controls.xaml

Any clues on how to resolve this are greatly appreciated!

ColumnChooser for GridView in a TabControl

Hello,

I have a RadTabControl. Inside every tab there is a UserControl with RadGridView. I want to add a RadDropDownButton with Column Chooser for the GridViews. Like this: http://docs.telerik.com/devtools/wpf/controls/radgridview/how-to/show-hide-columns-outside-of-the-radgridview.html I tried placing it in RadGridView.ControlPanelItems and everything works fine, but it takes a whole row for just one control. Can I put it in RadTabControl.AdditionalContent? How should I bind the Columns property right?

Disabled items can be selected with shift-click

I have a RadGridView with SelectionMode="Extended". The bound items have an IsEnabled property, and the rows are enabled or disabled using this property by modifying the style as follows:

    <uxt:UxtWindow.Resources>
        <Style TargetType="{x:Type telerik:GridViewRow}" BasedOn="{StaticResource GridViewRowStyle}">
            <Setter Property="IsEnabled" Value="{Binding Path=IsEnabled}"/>
        </Style>
    </uxt:UxtWindow.Resources>

This is fine in so far as the disabled rows are correctly displayed greyed-out, if I click on a disabled row it is not selected and if I click on a disabled row with Control held down it is also not selected. The problem is that if I click on a row above a disabled row, hold down Shift and then click on a row below the disabled row, all the rows between the two clicked-on rows are selected including the disabled row.

Is this a bug and is there anything I can do about it?

CellValidation: Set other cell invalid + ErrorMessage

Hello!

Is there a way to set cell B invalid in cell-A-validation?

For example:
cell A - customer-ID
cell B - country

1. User sets the country (B) to Germany
2. User changes the customer-ID (A) <- this customer-ID does not allow Germany
3. Cell B should now be set invalid

kind regards

High contrast theme ?

Hey all.

I was just playing around with the new Office inspired templates (they look great !), and have a query.
When I set the Windows Theme to high contrast, the Telerik application does not follow suit, which is an issue where accessibility is concerned.

I've attached a screenshot to illustrate my point.

How to programmatically remove a child tree node?

Hi,

I'm having trouble trying to remove a treeview item programmatically.

I add tree items roughly like so:

RadTreeViewItem item = new RadTreeViewItem();

item.Header = "Header 1";

item.Tag = myProperty;

treeProducts.Add(item);

I then try to use the following method to remove the desired TreeItem:

//Get Selected Tree Item

RadTreeViewItem treeViewItem = (RadTreeViewItem)treeProducts.SelectedItem;

//Remove TreeView Item

this.treeProducts.Items.Remove(treeViewItem);

For some reason it will only remove "TOP LEVEL" tree items and not items that are child nodes.

Do you know how I can programmatically remove a TreeItem that isn't a top level node?

I can see that it has something to do with the RadTreeView Items Collection, where it only lists all top level nodes.

Thank you for time,

Rob

Cell + Column.IsReadOnlyBinding

Hello,

Is there a way to detect if a cell is set readonly by the IsReadOnlyBinding property of the parent column?

I need it for two reasons:

1. I want do display text inside _all_ readonly cells in Italics. The preferred way to do this would be some Trigger in the ControlTemplate of the GridViewCell (I have created my own cell template anyway).

2. I have to check it before entering edit mode. I manually set the IsInEditMode property of the cell on MouseUp, not on MouseDown (as default), as MouseDown should only select the cell.
