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?

[Solved] 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.

[Solved] 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.

RowStyleSelector when using ObservableCollection

Hi,

I am trying to use RowStyleSelector with a RadGridView having an ItemsSource of type ObservableCollection<T>. The RowStyleSelector looks at the value of a property of T to set the background color of the corresponding row.

My problem is that the items may be altered outside of the grid. The new values are immediately picked up by the cells of the grid (because of the ObservableCollection and because T implements INotifyPropertyChanged), but the row style is not updated accordingly. However, if I sort the grid by clicking on one of the columns, the row styles are updated.

How can I ensure that the style is updated as soon as the values of the cells are updated?

In case it matters, this is how the RadGridView is declared (stripped down a bit):

<telerik:RadGridView Name="DocumentGrid" SelectionMode="Extended" ItemsSource="{Binding Path=Documents}" AutoGenerateColumns="False" IsReadOnly="True" RowStyleSelector="{StaticResource DocumentStyleSelector}">

This is the RowStyleSelector (stripped down a bit):

internal class DocumentStyleSelector : StyleSelector

{

public Style DocumentModifiedStyle { get; set; }

public override Style SelectStyle(object item, DependencyObject container)

{

var document = item as Document;

if (document != null && document.EntityState == EntityState.Modified)

{

return DocumentModifiedStyle;

}

return null;
