Hello. I want scrolling my RadDiagram.

When I add some shape on diagram in runtime, scroll still not enable. Maybe I need do some refresh diagram? Help me, please.

Hi all,
I need to know if the last version  of Telerik WPF supports .NET 3.5 SP1.

Thank you,
Emanuele

Hi all,

I have a treeview as outlined below. Whenever an item is checked/unchecked, I 'do something' in the code-behind.

However, if the user checks the root, all items are checked /unchecked and I get an event for each. I just want to know when it's done so I can inspect the state of the relevant items.

I can't find a relevant event; even mouseDown doesn't seem to 'fire' in my case?! What could you recommend?

Thanks for any commments,

Anders, Denmark

Hi,
I'm developing an application that users can drag and drop items on a  radmap and move them around. I wanted to use ClusteredDataSource for drill down ability, but i'm struggling on binding the location property of my custom class.

here is my custom object:
    public class ToolboxItem : ContentControl
    {
        public String IconPath { get; set; }

        public String Description { get; set; }

        public Location Location { get; set; }

    }

And my ObservableCollection :

    public class ItemsDataSource : ObservableCollection<ToolboxItem>
    {
        Random rnd = new Random();

        public ItemsDataSource()
        {
            this.GeoBoundsNW = new Location(39, -120);
            this.GeoBoundsSE = new Location(32, -113);
            CreatePointsInRect(100);
        }

        private LocationRect dataRectangle = new LocationRect();
        public LocationRect DataRectangle
        {
            get { return dataRectangle; }
            set
            {
                dataRectangle = value;
            }
        }

        private Location geoBoundsNW = Location.Empty;
        public Location GeoBoundsNW
        {
            get { return geoBoundsNW; }
            set
            {
                geoBoundsNW = value;
                UpdateGeoBounds();
            }
        }

        private Location geoBoundsSE = Location.Empty;
        public Location GeoBoundsSE
        {
            get { return geoBoundsSE; }
            set
            {
                geoBoundsSE = value;
                UpdateGeoBounds();
            }
        }

        private void UpdateGeoBounds()
        {
            if (!this.GeoBoundsNW.IsEmpty && !this.GeoBoundsSE.IsEmpty)
            {
                this.DataRectangle = new LocationRect(this.GeoBoundsNW, this.GeoBoundsSE);
            }
        }

        #region Test
        private void CreatePointsInRect(int count)
        {
            if (!this.dataRectangle.IsEmpty)
            {
                for (int i = 0; i < count; i++)
                {
                    ToolboxItem item = new ToolboxItem();
                    Location loc = new Location(
                        this.DataRectangle.North - this.DataRectangle.GeoSize.Height * rnd.NextDouble(),
                        this.DataRectangle.West + this.DataRectangle.GeoSize.Width * rnd.NextDouble());
                    item.Name = "item" + i;
                    item.Location = loc;
                    
                    this.Add(item);
                }
            }
        }
        #endregion

    }

and my clustered data source defiifnition in xaml file:

                    <local:ItemsDataSource x:Key="ItemsDataSource" />

                    <telerik:ClusteredDataSource x:Key="clusteredDataSource"
                                                 ClusterItemTemplate="{StaticResource ClusterTemplate}"
                                                 ItemTemplate="{StaticResource ClusteredItemTemplate}"
                                                 GenerateClustersOnZoom="True"
                                                 ItemsSource="{StaticResource ItemsDataSource}">

                    </telerik:ClusteredDataSource>

and of course my rad map control:

        <telerik:RadMap Name="radMap"
                        AllowDrop="True"
                        Grid.Column="2"
                        Grid.Row="1"
                        ZoomBarVisibility="Collapsed"
                        ZoomLevel="4"
                        Center="39,-120">
            <telerik:RadMap.Provider>
                <telerik:OpenStreetMapProvider />
            </telerik:RadMap.Provider>
            <telerik:InformationLayer x:Name="infLayer" AllowDrop="True"
                                      ClusteredDataSource="{StaticResource clusteredDataSource}">
            </telerik:InformationLayer>
        </telerik:RadMap>

and Clustered Item Template :
                    <DataTemplate x:Key="ClusteredItemTemplate">
                        <telerik:MapPinPoint telerik:MapLayer.Location= "{Binding Converter={StaticResource locConverter}}"
                                             MouseLeftButtonUp="ClusteredItemMouseClick"/>
                    </DataTemplate>

On data template i tried to bind Location property of my ToolboxItem but it was an unsuccessful attempt so then i provided an IValueConverter which is just below.

    public class LocationConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            var item = value as ClusteredItem;
            var toolboxItem = item.Data as ToolboxItem;

            return toolboxItem.Location;
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }

    }


The problem is if i change type of the ObservableCollection to Location it works perfectly, but i need to provide additional information for the visual and also for the status of the item. So i have to use my ToolboxItem as a type on my ObservableCollection, but i couldn't bind the Location property from toolboxItem.

Does anybody have any idea how to do that.

Thanks,

Hello,

I have a sparkline in a time bar, and I am looking to match the x values of the sparkline with the times of the timebar.  Currently, the first item in the sparkline is always shown at the start of the timebar, no matter if the times match or not.  Is there a way I can do this?

Thanks,
Eric

Whenever I type into a MaskedTextInput the words have a space.   Whenever the box loses focuses the spaces are truncated and the resultant combined single phrase is left in the box.  Once that box gains the focus again the phrase is broken out into its separate words again.  Is there a to prevent this from happening and have it not truncate the spaces whenever the boxes don't have focus?

Also, I can't seem to get the boxes character limit past 20 some odd characters.  Is there a way to increase that limit?

Thanks for any help.

Hello,

i created any GridViewComboBoxColumns on code behind with:


        private void MyGridView_AutoGeneratingColumn(object sender, Telerik.Windows.Controls.GridViewAutoGeneratingColumnEventArgs e)
        {
            DirInfoPropertyDescriptor propertyDecriptor = e.ItemPropertyInfo.Descriptor as DirInfoPropertyDescriptor;
            GridViewDataColumn datacolumn = e.Column as GridViewDataColumn;
            if (datacolumn != null)
            {
                IList<FieldDropDownItem> dropdownItems = DirInfo.FieldsDropdownItemsCache[propertyDecriptor.Name];
                if(dropdownItems.Count != 0)
                {
                    GridViewComboBoxColumn comboColumn = new GridViewComboBoxColumn();
                    comboColumn.Header = datacolumn.Header;
                    comboColumn.DataMemberBinding = datacolumn.DataMemberBinding;
                    comboColumn.SelectedValueMemberPath = "Id";
                    comboColumn.DisplayMemberPath = "Description";
                    comboColumn.SortMemberPath = "Description";
                    comboColumn.ItemsSource = dropdownItems;
                    (sender as RadGridView).Columns.Add(comboColumn);
                    e.Cancel = true;
                }                    
            }           
        }
It works nice: i can see and edit my dropdown values, but i cant sort.
After sorting my grid is empty, see screenshot

I am upgrading from Q3 2011 to Q2 2012 and ran into a problem with the numeric input.  I cannot enter a negative value into my textboxes.  It doesn't throw an error - it just ignores the negative sign.  I have tried the number pad and the regular keyboard and I have tried entering the negative first and entering it last.  Nothing seems to work.
See below for an example of one of the text boxes.  I checked the value in the validator and it is positive there so it isn't the validator changing the value.

My boss just showed this to me, though it's been in the application for a while.  If a user double clicks on the divider between columns in the column header on this one RadGridView control in my app, the following exception is thrown:


Here is the XAML for the RadGridView in question:


With some experimenting, I've found that the exception is thrown only if you click on those columns that contain "*" in their Widths.  if you set it to Auto or a fixed value, it doesn't happen.

Hi,

I have a code similar to this:

        RadWindow.Confirm("Are you sure?", AddressOf OnClosed)
MessageBox ("Hi World")        

The alert or message always show it....regardless of response, in fact is an immediate action.

Is there a way that predefined windows you can wait for confirmation or selection by the user?

Something like Windows Desktop. NET:

If (message) = vbYes Then
MessageBox ("Hi World")     
End If

In advance, thank you all.
