Hello,

I am trying to read in a bunch of data from a stored procedure and I build out multiple data series in the same order that it was received from the stored procedure. The problem lies in that the order of the data from the stored procedure is not the same order that RadChart renders the XCategories. For instance, I am reading in the XCategory's as Apr-2009, June-2009... till now. But the XCategory's wind up being alphabetized rather than ordered by the order specified in the stored procedure. Is there a good way to re-order the XCategories so they appear chronologically?

Thanks,
Sean

I'm trying to change the color of a RadDataForm, when it's disabled.

I've found these instructions: http://www.telerik.com/help/wpf/raddatafor-styles-and-templates-styling-raddataform.html

But when I load my solution file in Microsoft Expression Blend 4, I get exceptions:

XamlParseException: 'Office_Black' is not a valid value for property 'Theme'.

Hi,

We use RadGridView 2011.2.920.35 . We have problems getting focus on our grids. If we have two grids side-by-side and focus is on the first one, clicking the header of one the columns of the second grid doesn't switch focus to that grid. This is a real problem when the grids are empty and the headers are the only thing displayed of the grid. Focus switching does work with other grid elements (background, groupbox, even clicking on the little filter icon in the header).

Is this known behavior? If so, how can I change it? If not, is there any other information I can provide to reproduce this issue and get help?

Bye,
Steven

Hi,

I have used the EditorTemplateRules to created custom filters for various properties based on their name (i.e. combo boxes populated with appropriate data).

What I would like to do now is create a rule based on property type rather than property name.  I want all properties of type DateTime (or DateTime?) to use a custom control.

Is this possible?

Thanks.

Hello,

in my Table-Control which is based on the RadGridView I'm trying to set an AttachedDependencyProperty for each GridViewCell.
My Problem is that I reached my Handler only for Rows of the Type CheckBoxColumn and ComboBoxColumn.

public class Table : RadGridView
{
    public Table()
    {
        EventManager.RegisterClassHandler(typeof(GridViewCellBase), LoadedEvent, new RoutedEventHandler(OnGridViewCellLoaded), true);
    }
     
    private static void OnGridViewCellLoaded(object sender, RoutedEventArgs e)
    {
        var cell = sender as GridViewCellBase;
        if (cell != null)
        {
            var dataType = cell.DataColumn.DataType;
            if (dataType == typeof(int) || dataType == typeof(double) || dataType == typeof(float) || dataType == typeof(decimal))
            {
                cell.SetValue(Table.NumberColumnProperty, true);
            }
        }
    }
     
    public static bool GetNumberColumn(DependencyObject obj)
    {
       return (bool)obj.GetValue(NumberColumnProperty);
    }
 
    public static void SetNumberColumn(DependencyObject obj, bool value)
    {
        obj.SetValue(NumberColumnProperty, value);
    }
 
    public static readonly DependencyProperty NumberColumnProperty =
            DependencyProperty.RegisterAttached("NumberColumn", typeof(bool), typeof(Table),
            new FrameworkPropertyMetadata(false, FrameworkPropertyMetadataOptions.AffectsMeasure | FrameworkPropertyMetadataOptions.AffectsRender | FrameworkPropertyMetadataOptions.Inherits));
 
}

I would like to add some static text to the Comparative Measure element.  I have re-templated the bullet graph, but my attempts to add the text does not seem to work.  I would like the text to float at the top right of the line.  Is this possible?

Here is my style template:

<Style x:Key="RadHorizontalBulletGraphStyle" TargetType="telerik:RadHorizontalBulletGraph">
    <Setter Property="ComparativeMeasureThickness" Value="1"/>
    <Setter Property="FontSize" Value="10"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="telerik:RadHorizontalBulletGraph">
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="5*"/>
                        <RowDefinition Height="5*"/>
                    </Grid.RowDefinitions>
                    <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="White" Grid.Row="0">
                        <Grid>
                            <Grid>
                                <Grid.Resources>
                                    <Style TargetType="telerik:BarItem">
                                        <Setter Property="LengthPercent" Value="1" />
                                    </Style>
                                </Grid.Resources>
                                <Grid.RowDefinitions>
                                    <RowDefinition Height="5*" />
                                    <RowDefinition Height="5*" />
                                </Grid.RowDefinitions>
                                <telerik:FeaturedMeasurePresenter Grid.Row="0" Content="{TemplateBinding FeaturedMeasureInternal}" Margin="0,5" />
                                <telerik:FeaturedMeasurePresenter Grid.Row="1" Content="{TemplateBinding ProjectedMeasureInternal}" Margin="0,5"  />
                            </Grid>
                            <StackPanel HorizontalAlignment="Stretch">
                                <telerik:ComparativeMeasuresContainer ChildrenSource="{TemplateBinding MergedComparativeMeasures}" Range="{TemplateBinding Range}" Margin="-15" />
                            </StackPanel>
                        </Grid>
                    </Border>
                    <telerik:QuantitativeScaleContainer Grid.Row="1" TextFormatString="{TemplateBinding TextFormatString}" Visibility="{TemplateBinding QuantitativeScaleVisibility}" Opacity="0.5" RenderTransformOrigin="0.5,0.5" Range="{TemplateBinding Range}"  >
                        <telerik:QuantitativeScaleContainer.RenderTransform>
                            <TranslateTransform Y="5"/>
                        </telerik:QuantitativeScaleContainer.RenderTransform>
                    </telerik:QuantitativeScaleContainer>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
<SolidColorBrush x:Key="ActualBrush" Color="Green" />
<SolidColorBrush x:Key="TargetBrush" Color="Red" />

And here is my control definition:

<telerik:RadHorizontalBulletGraph TextFormatString="${0}"
                                  ProjectedValue="150"
                                  FeaturedMeasure="200"
                                  ComparativeMeasure="175"
                                  Height="100"
                                  Style="{StaticResource RadHorizontalBulletGraphStyle}"
                                  FeaturedMeasureBrush="{StaticResource ActualBrush}"
                                  ProjectedValueBrush="{StaticResource TargetBrush}"
                                  Step="200" />

Telrik doesn't install on the machine. We use dll from library. What does this path ment?

If you need more information - please, tell what is it - I try to get it for you.

Thanks!

Hi

Seems to me Permissionranges have their own background color
(probably to indicate an editable range).
I'd like to actively set this color, but don't know how.
PermissionRangeInfo.Color is readonly.
How can I do it? By a StyleDefinition?

Regards,
Chris

Hi,

I have 2 forms, FormA & FormB, both was created but only one at a time can be visible. Each form have an existing StoradId property. When I click on my button "Save persistence" in my FormB, both forms persistence are save at the same time on disk???

If it's normal, can you tell me if it's possible to only save the persistence of the form from where the code is called?

Here is my persistence class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Telerik.Windows.Persistence;
using Telerik.Windows.Persistence.Storage;

namespace WpfApplication_Docking
{
    static public class PersistenceStorage
    {
        #region Public methods.
        /// <summary>
        /// Load/Save all controls that contain "telerik:PersistenceManager.StorageId="..."
        /// The file location is "$APPDATA\IsolatedStorage\..."
        /// </summary>
        /// <param name="pPersistenceAction">Load/Save</param>
        /// <param name="pErrorMessage">Error received during the persistence.</param>
        /// <returns>true if successfull otherwise false</returns>
        static public bool Persist(PersistenceAction pPersistenceAction, out string pErrorMessage)
        {
   

            pErrorMessage = string.Empty;
            PersistenceManager manager = new PersistenceManager();
            //manager.PropertyPersisting += new Telerik.Windows.Persistence.Events.PropertyPersistingEventHandler(manager_PropertyPersisting);
            IsolatedStorageProvider storage = new IsolatedStorageProvider(manager);

            try
            {
                try
                {
                    if (pPersistenceAction == PersistenceAction.Load)
                    {
                        storage.LoadFromStorage();
                    }
                    else if (pPersistenceAction == PersistenceAction.Save)
                    {
                        storage.SaveToStorage();
                    }

                    return true;
                }
                catch (Exception ex)
                {
                    pErrorMessage = ex.Message;
                    return false;
                }
            }
            finally
            {
                //manager.PropertyPersisting += new Telerik.Windows.Persistence.Events.PropertyPersistingEventHandler(manager_PropertyPersisting);
            }
        }

        /// <summary>
        /// Event triggered when the stream persistence didn't worked.
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        static void manager_PersistenceError(object sender, Telerik.Windows.Persistence.Events.PersistenceErrorEventArgs e)
        {
            mErrorMessage = e.Exception.Message;
            mResult = false;
            throw new NotImplementedException();
        }

        /// <summary>
        /// This event is used to prevent any BroderBrush to have a transparent color when we persist an object.
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        static void manager_PropertyPersisting(object sender, Telerik.Windows.Persistence.Events.PersistingPropertyEventArgs e)
        {
            //Not needed since version 2011.3.1116.35 of Telerik
            //if (e.Name == "BorderBrush")
            //    e.Cancel = true;
        }
        #endregion

        #region Enumerators.
        public enum PersistenceAction { Load, Save }
        #endregion

        #region Private declarations.
        static private string mErrorMessage;
        static private bool mResult;
