Anyone know how to grey out a row within a gridview.

I want to be able to see the row, just basically dimmed?

Any ideas?

RadGridView, ObservableCollection and currentitem

Hi
I'm trying to replace my wpf listview with radgridview, but the selecteditem binding to the observablecollection does not work.

<ListView Name="lboRoles" Grid.Row="1" Grid.Column="0" ItemsSource="{Binding}" Grid.ColumnSpan="1" IsSynchronizedWithCurrentItem="True" SelectionMode="Single" >

<ListView.View>

<GridView>

<GridViewColumn Header="Name" Width="200" DisplayMemberBinding="{Binding Path=Name}"/>

<GridViewColumn Header="Description" Width="200" DisplayMemberBinding="{Binding Path=Description}"/>

</GridView>

</ListView.View>

</ListView>

<mytelerik:RadGridView x:Name="gvRoles" ItemsSource="{Binding}" SelectionMode="Single" IsReadOnly="True"

Grid.Column="0" Grid.Row="0" IsSynchronizedWithCurrentItem="True" AutoGenerateColumns="False"

ShowGroupPanel="False" CanUserFreezeColumns="False" ShowColumnFooters="False">

<mytelerik:RadGridView.Columns>

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

</mytelerik:GridViewDataColumn>

<mytelerik:GridViewDataColumn Header="Description" DataMemberBinding="{Binding Description}">

</mytelerik:GridViewDataColumn>

</mytelerik:RadGridView.Columns>

</mytelerik:RadGridView>

When selecting a row in the listview, the observablecollection currentrow is changed, but not when selecting a row in the radgridview.
Is there a different way to do this with radgridview? Do I need a binding to selecteditem?

RowIsExpandedChanged and CollapseHierarchyItem

Hi,

I am trying to have a single expand Hierarchy in my GridView, in the RowIsExpandedChanged events i am checking if the row is expanded and i am collapsing the other rows with the CollapseHierarchyItem.

What is happening is that the RowIsExpandedChanged event is raised again when calling CollapseHierarchyItem, how to collapse rows without firing the RowIsExpandedChanged events.

Thanks.

RowHeight...

Is it possible for the user to set the row height by dragging the mouse on the border of a row - similar to the way column sizing works??

Starting with Telerik controls

Hi,
I download the RADcontrols for WPF4.0 trial to test some examples.

I open ExamplesCS_WPF Solution and set the project Examples.Xbap as starting project

when i compile i get this errors:

Error 12 Unexpected error creating debug information file 'C:\Program Files\Telerik\RadControls for WPF Q1 2011\Demos\Examples.Xbap\obj\Debug\Telerik.Windows.Examples.PDB' -- 'Unspecified error ' Examples.Xbap

Error 13 Unexpected error creating debug information file 'C:\Program Files\Telerik\RadControls for WPF Q1 2011\Demos\Examples.WPF\obj\x86\Debug\Telerik.Windows.Examples.PDB' -- 'Unspecified error ' Examples.WPF

The demos online works but not the version for download.

Am I doing something wrong? (i didn't find any step by step tutorial for executing the examples)

Is there some tutorial for making my own demos using the rad controls?

Greetings.

Strange behavior with TabIndex

Hello,

I had some troubles with the behavior of the RadTabControl with 2010 Q3. This has improved with 2011 Q1, or maybe I just got better at handling the Telerik controls. But it still behaves strangely when I set the TabIndex of the controls within the TabItems.

<Window x:Class="WPFApplication1.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="Window1">

<StackPanel>

<telerik:RadMaskedTextBox MaskType="None" MaskedText="Text1" IsTabStop="True" TabIndex="1" />

<telerik:RadTabControl>

<telerik:RadTabItem Header="Header 1" IsTabStop="True" TabIndex="2" IsSelected="True">

<StackPanel>

<telerik:RadMaskedTextBox MaskType="None" MaskedText="Text2" IsTabStop="True" TabIndex="3" />

<telerik:RadMaskedTextBox MaskType="None" MaskedText="Text3" IsTabStop="True" TabIndex="4" />

</StackPanel>

</telerik:RadTabItem>

<telerik:RadTabItem Header="Header 2" IsTabStop="True" TabIndex="5">

<StackPanel>

<telerik:RadMaskedTextBox MaskType="None" MaskedText="Text4" IsTabStop="True" TabIndex="6" />

<telerik:RadMaskedTextBox MaskType="None" MaskedText="Text5" IsTabStop="True" TabIndex="7" />

</StackPanel>

</telerik:RadTabItem>

</telerik:RadTabControl>

</StackPanel>

</Window>

In the small example above the focus moves from the TextBox with "Text1" to that with "Text2" then to the one with "Text3" and only then to the TabItem with "Header 1", although that has a lower TabIndex and should come first. If I remove the TabIndex property from the controls within the TabItems the behavior is as expected and the focus is on the header before it is on "Text2".

In this simple example it doesn't really matter of course, the TabIndex property is not needed for correct movement within the TabItems. In all the cases I can think of right now the position of the control within the xaml code should be sufficient to ensure the right order. There may however be some situation requiring TabIndices and then they should work correctly.
