Sorting RadGridView and data virtualization

hello, i have a problem with my project.

i am using 2013 version of telerik,

i have a RadGridView with about 40-50 records , which spread across 2-3 pages.

i want to sort them by a column, but due to lazy loading it sorts only the specific page i am in.

i have tried to disable lazy loading by using the command EnableRowVirtualization="false", but without success.

does any newer version have a solution to this problem, or any other solution?

thank you very much,

elad.

SuspendNotifications not working for me

I'm trying to build out some functionality that will allow users to enter in multiple filters and then once they have entered in all of their filters, they can click button and execute complete set of filters.

I'm trying to do this by calling grid's FilterDescriptors.SuspendNotifications() (via a checkbox checked event) and SuspendNotifications on all of the individual columns ColumnFilterDescriptor.

Once the user has entered in their filters, I want to allow them to uncheck the check box, which calls the gird's FilterDescriptors.ResumeNotifications() and ResumeNotifications on all of the individual columns ColumnFilterDescriptor.

What I'm seeing in my sample project is that everything works as expected when the application starts up. I enter in a few filters, I uncheck the suspend check box, and the data is fitlered, correctly.

When I re-check the suspend check box, I can go and delete values and the UI updates (Not what I expected since all notifications were suspended).

Any suggestions or ideas? Am I missing something obvious? In my attached screenshot, I expected 3 rows of data, not one since filtering was suspended.

Thanks,

Cyrus

[Solved] Unable to display a RadWindow

I've been going at this for 2 hours. I don't understand why it's so hard to display a simple RadWindow.

PreferencesView.xaml

<telerik:RadWindow x:Class="MainWindow.Preferences.PreferencesView"

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

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

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

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

xmlns:local="clr-namespace:MainWindow.Preferences"

mc:Ignorable="d"

Height="350" Width="300">

<DockPanel Margin="10">

<StackPanel DockPanel.Dock="Bottom" Orientation="Horizontal" VerticalAlignment="Bottom" HorizontalAlignment="Right">

<telerik:RadButton Content="OK" />

<telerik:RadButton Content="Cancel" Margin="5,0,0,0" />

</StackPanel>

</DockPanel>

</telerik:RadWindow>

Caller

PreferencesView preferencesView = new PreferencesView();

preferencesView.ResizeMode = ResizeMode.NoResize;

preferencesView.WindowStartupLocation = WindowStartupLocation.CenterOwner;

preferencesView.Owner = this;

preferencesView.ShowDialog();

The RadWindow seems to exist because I can show its system menu with Alt-Space. For some reason, I only see a think frame of the RadWindow and its entire content is blank. I do use a global theme that I've set in App.xaml and my MainWindow uses it fine.

What am I doing wrong?

Q3 SP1 Blend Toolbox Items

Hi,

I just install UI for WPF Q3_sp1 on a clean Windows 10 machine with VS2015 installed.

The setup option "Blend Toolbox Items" is marked with an X (not available).

When I enter "customize" it's not visible in the tree.

Am I missing something or is Blend for VS2015 not supported?

Regards

[Solved] GridViewColumn Width behavior changed

Hi,

Since UI WPF Q3 2015, I notice change in the GridView column auto size. I have the following simple user control (with no height and width) :

<UserControl x:Class="WpfApplication1.UserControl1"

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

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

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:local="clr-namespace:WpfApplication1"

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

mc:Ignorable="d"

d:DesignHeight="300" d:DesignWidth="300">

<Grid>

<telerik:RadGridView AutoGenerateColumns="False">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Name" Width="150"/>

<telerik:GridViewDataColumn Header="Description" Width="*"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

</UserControl>

In my MainWindow I have a button which show a RadWindow with the UserControl content :

private void OnClick(object sender, RoutedEventArgs e)

{

RadWindow window = new RadWindow();

window.SizeToContent = true;

window.Content = new UserControl1();

window.SizeChanged += delegate

{

window.Header = string.Format("({0}, {1})", window.Height, window.Width);

};

window.ShowDialog();

}

In Telerik 2015.2.728.45, the RadWindow size is correct (like i expect in fact). In Telerik 2015.3.* the gridcolumn with Width="*" take all width possible (infinite?) and radwindow Width become infinite.

What's the correct behavior ? Telerik 2015.2 or 2015.3 ? Do I need to set the UserControl size ? (I prefer to avoid this solution like my real application is more complex and expect to have an UserControl resize from its content).

Thanks

Regards

Restting the layout runtime

Is it possible to reset the layout of a wpf control at runtime. My scenario is that if I add a column to a persisted grid view the user will not be able to see it unless they delete their settings. Is there a way to reset to the default layout during runtime?

Bind Font Size of HeaderCellStyle

Hi,

I currently have a problem applying a bound size to the HeaderCellStyle.FontSize

Our operators have the possibility to set the text size to what they need.

I would like to have it bound like the FontSize for the GridCells in the following code snippet:

FontSize="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type lisaGridControl:LisaGridControl}}, Path=SettingsModel.GeneralSettings.FontSize, Mode=TwoWay}"

The proplem is that I can only find static solutions like:

<Style x:Key="GridHeaderCellStyle" TargetType="{x:Type telerik:GridViewHeaderCell}">

<Setter Property="Foreground" Value="Black" />

<Setter Property="FontSize" Value="16" />

<Setter Property="FontWeight" Value="Normal" />

<Setter Property="FontStyle" Value="Normal" />

</Style>

Additionally my columns are created in code behind and I have no column definition in xaml.

For example the DisplayText for the header is bound as follows:

var bindingHeader = new Binding("DisplayText") { Source = column, ValidatesOnDataErrors = false, Mode = BindingMode.OneWay };

if (column.GridColumn == null)

{

throw new Exception("column.GridColumn(" + column.DisplayText + ")==null");

}

column.GridColumn.SetBinding(GridViewColumn.HeaderProperty, bindingHeader);

Thanks for any suggestions

Best regards

VS 2015: Xaml IntelliSense not working

Hi guys!

I installed the new Visual Studio 2015, and created a new Telerik WPF project with reference to Telerik.Windows.Controls, Telerik.Windows.Controls.GridView, Telerik.Windows.Controls.Navaigation etc.

I'm using implicit styles.

Now I want add some Telerik control, but the IntelliSense is not working!

<Window x:Class="TestWithNavigation.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">

<Grid>

<telerik: ***** The IntelliSense NOT WORKING ********

</Grid>

</Window>

If I drop the reference to Telerik.Windows.Controls.Navigation, it's working well.
