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" />

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;

When you have no text in your RichTextBox  and you hit the 'tab' key, it looks like it jumps from Tab position to Tab position withinin the textbox.

When you have text and you hit 'tab' key after you type a character, then it looks like it just adds a few spaces. Why does it not jump to the next Tab position?

Is there a setting to change this behavior?

My users would like to be able to line up text(of variable font sizes) across different lines based on these tab postions.

Hi there,

In my Radgridview, I have populated a list of objects.
I have added a culomn that contains a radButton with content = "Edit".
I have a nother window that will take an object as parameter, and opens it in the new window after clicking on Edit button.

The problem is:
when i click on Edit button inside the radgridview, It always sends the top row in the grid. I'm using "CurrentItem".
the selectedItem is always null unless i select the row by clicking it before pushing the Edit button.

My Question is:
How do i send the current row object (the row where the button was clicked) to the new window?

Thank you...

I have a RadGridView that displays summary data for a group of parent records.

On it I have a HierarchyChildTemplate, defining another RadGridView that displays summary data for a group of child records. In this inner grid, I have a RowDetailsTemplate that contains a RadDataForm that displays detailed data for the child records. The inner grid has RowDetailsVisibilityMode="VisibileWhenSelected".

What I want is to add a context menu that toggles RowDetailsVisibilityMode to "Collapsed".

I have a reference to the parent grid. What I can't figure out is how to get a reference to the child grids that are generated from the template.
