Hi

We would like to implement OpenDropDownOnFocus for AutoCompleteBox ( RadComboBox has this property and this behavior).
We override the default AutoCompeteBox Style .
How can we do that?
Thanks

Hi,

I have used the following blog to get some varying sized tiles which is great but I would like my users to be able to adjust tile sizes themselves.

http://blogs.telerik.com/xamlteam/posts/11-06-25/new-tileview-features.aspx

Is there any way that you can resize a tile by dragging on its bottom right corner?

I can do it by putting a button on the tile and in the button press adjust the RestoredWidth and RestoredHeight of the tile but this is not a great UI experience.

Thanks
Anthony

Hi

I’m using RadGridView in my application. I have set style of Template Property of GridView with Blend.

The problem is that GroupPanel and GroupFooter are shown even after I have set:

radGridView1.ShowGroupFooters = false;

radGridView1.ShowGroupPanel= false;

 
Is there anything wrong with my
style?

The following is my style:

    <Style x:Key="CustomGridViewStyle" TargetType="{x:Type telerik:RadGridView}" BasedOn="{StaticResource ResourceKey=RadGridViewStyle}">

        <Setter Property="Template">

            <Setter.Value>

                <ControlTemplate TargetType="telerik:RadGridView">

Hi,

I'm trying to close a RadWindow from my view model. I've bound DialogResult to my view model but setting it doesn't seem to close the window.

Is there something I'm missing or does the RadWindow only support being closed by calling it's Close event?

Any help would be appreciated.

I am coding in C#, using the MVVM pattern. I have a Main Window that uses several User Controls. I am trying to pass string data fro the Main Window to the View Model of the User Control. So far I have been able to pass the Main Window data to the User Control View and View code behind. However, I can't seem to expose that data to the User Control View Model. Here is what does work:

Main Window XAML,

UCV:SetupUC UC1="{Binding DataContext.ContainerData, ElementName=winCon, Mode=TwoWay}">
</UCV:SetupUC>

User Control XAML,

<TextBox x:Name="tbx1" HorizontalAlignment="Left" Height="23" Margin="159,22,0,0" TextWrapping="Wrap" Text="{Binding UC1, ElementName=root, UpdateSourceTrigger=PropertyChanged}" VerticalAlignment="Top" Width="120" RenderTransformOrigin="0.017,0.304"/>

User Control XAML code behind,

public partial class SetupUC : UserControl, INotifyPropertyChanged
    {

        public static readonly DependencyProperty UC1Property =
    DependencyProperty.Register(
      "UC1", typeof(string), typeof(SetupUC),
        new FrameworkPropertyMetadata()
        {
            PropertyChangedCallback = OnUC1Changed,
            BindsTwoWayByDefault = true
        });
        public string UC1
        {
            get { return (string)GetValue(UC1Property); }
            set
            {
                SetValue(UC1Property, value);
            }
        }
        private static void OnUC1Changed(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            if (e.OldValue != e.NewValue)
            {
                // code to be executed on value update
            }
        }
        public SetupUC()
        {
            InitializeComponent();
            SetupViewModel svm = new SetupViewModel();
            this.DataContext = svm;
            Binding binding = new Binding("ViewModelStringProperty") { Source = svm, Mode = BindingMode.TwoWay };
            BindingOperations.SetBinding(this, SetupUC.UC1Property, binding);
        }

The last 2 lines above are an attempt to bind the DP to a property in the User Control View Model - which other posts have suggested as a possible solution. I have not been able to get the binding to work. Again, the TextBox x:Name="tbx1" is displaying the DP, UC1, just fine; it changes "realtime" when the bound data in the Main Window changes.

Hello All.
I've a scenario when I use RadGridView linked with QueryableDataProvider.
QueryableDataProvider accepts IQueryable linked with DBContext.
In RadGridView in UI I did groping by one column and sorting by another column

class A : TEntity
{
    public string P1;
    public string P2;
}

Group by P1 and sort by P2 over UI.

In case, IQueriable points to in memory collection, everything works fine.
But when IQueriable points to IDbSet<TEntity> - sorting is not applied.
One difference between my tests is in "ToList()" called on IQueriable passed to QueryableDataProvider constructor.
Unfortunately, I cannot use InMemory collection.
Telerik version is 2014.1.331.45

I use the RadTimePicker on the GridViewDataColumn.

I want to be seen as 24 hours.

Can not use this.radTimePickerStartOn.Culture.DateTimeFormat.ShortTimePattern = "HH:mm:ss";

What should I do?

</Style>

 and 

<telerik:RadGridView.ItemContainerStyle>
  <Style TargetType="{x:Type telerik:GridViewRow}">

SelectedYN is a property in my viewModel.(Its updates the ItemsSource)

Please help me in this issue.

How can i draw a histogram on the Radslider like the image shown bellow using c# wpf?
How to add a histogram on RadSlider based on high and low values.I am attaching the image

Hi,

I am using version 2014.1.224.45 of UI for WPF. I need to make my docking control fill all my client area of its parent UserControl.

If i do not explicitly define a Height I receive the error: "Placing Docking control in a panel or control that measures it with infinite width or height is not supported in the current version."

Is it possible?
How can I do this ?

If the is not really possible which events I must drive to define explicitly the heit as the hight of the parent. I have treid the SizeChanged Event of the parent bit it did not work.

Thanks in advance
