HELP!!! Tile Placement Is Wrong -- Different Sizes

Hi,

I am having issues with trying to get my tiles in restored mode to "fill in" when one tile is bigger than the others.
I have a RadTileView which needs to show 7 panels (tile in position 0 is going to be 100% height and 50% width of the tile viewer). The rest of the tiles are sized so they should fit in the remaining space available, however 3 of the tiles align themselves below the tile in position 0. This means they are not visible and the user has to scroll.

I tried following the article - http://blogs.telerik.com/zarkovidolov/posts/11-06-25/new-tileview-features.aspx
and tried downloading the sample but the link is bad.

Here is my xaml, which I am hoping that you will be able to help me:

<telerik:RadTileView Grid.Row="0" x:Name="ChartTiles"

TileStateChangeTrigger="SingleClick"

telerik:StyleManager.Theme="Office_Blue"

ColumnsCount="3"

RowsCount="3"

ColumnWidth="Auto"

RowHeight="Auto"

MinimizedColumnWidth="300"

MinimizedRowHeight="300"

PreservePositionWhenMaximized="true"

IsItemsSizeInPercentages="True"

ItemsSource="{Binding ChartingViewModel.Charts}"

telerik:TileViewPanel.IsColumnsShrinkEnabled="True"

telerik:TileViewPanel.IsRowsShrinkEnabled="True"

telerik:TileViewPanel.IsSizeBoundToPosition="True"

TileStateChanged="ChartTiles_TileStateChanged"

Loaded="ChartTiles_Loaded"

TilesPositionChanged ="ChartTiles_TilesPositionChanged"

>

<telerik:RadTileView.ItemTemplate>

<DataTemplate>

<TextBlock Text="{Binding Name}" Style="{StaticResource tileItemStyle}"/>

</DataTemplate>

</telerik:RadTileView.ItemTemplate>

<telerik:RadTileView.ItemContainerStyle>

<Style TargetType="telerik:RadTileViewItem">

<Setter Property="RestoredHeight" Value="{Binding TileRestoredHeight, Mode=TwoWay}" />

<Setter Property="RestoredWidth" Value="{Binding TileRestoredWidth, Mode=TwoWay}" />

<Setter Property="ContextMenu" Value="{StaticResource ChartContextMenu}" />

</Style>

</telerik:RadTileView.ItemContainerStyle>

<telerik:RadTileView.ContentTemplate>

<DataTemplate>

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="30" />

<RowDefinition />

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>

<ColumnDefinition />

</Grid.ColumnDefinitions>

<Label Grid.Row="0" Grid.Column="0" HorizontalAlignment="Left" Content="{Binding Path=Title}"/>

<StackPanel Grid.Row="0" Grid.Column="1" HorizontalAlignment="Right" Orientation="Horizontal">

<RadioButton Content="Pie Chart" IsChecked="{Binding Path=IsPieChartActive}" Margin="0,5,0,5"/>

<RadioButton Content="Bar Chart" IsChecked="{Binding Path=IsBarChartActive}" Margin="5"/>

</StackPanel>

<ecaAnalyzerViews:PieChartControl Grid.Row="1" Grid.ColumnSpan="2"

Visibility="{Binding Path=PieChartVisibility, TargetNullValue=Collapsed, FallbackValue=Collapsed}"

/>

<ecaAnalyzerViews:BarChartControl Grid.Row="1" Grid.ColumnSpan="2"

Visibility="{Binding Path=BarChartVisibility, TargetNullValue=Collapsed, FallbackValue=Collapsed}"

/>

</Grid>

</DataTemplate>

</telerik:RadTileView.ContentTemplate>

</telerik:RadTileView>

Thanks in advance for any help!!!

appointment.RecurrenceRule = new RecurrenceRule(Pattern); ERROR

Hi,

i'm frustrated :-(
For me it's unpossible to add Patterns to an Appointment. The code above shows how i create my Pattern Objekt and how
i add this to my Appointment!

var Pattern = new RecurrencePattern();

Pattern.Frequency = Frequency_v;

Pattern.DayOrdinal = DayOrdinal_i;

Pattern.DaysOfWeekMask = DaysofWeekMask_v;

Pattern.FirstDayOfWeek = FirstDayofWeek_d;

Pattern.Frequency = Frequency_v;

Pattern.Interval = Convert.ToInt32(tasks_dr.Field<Int64>("Interval"));

Pattern.MaxOccurrences = Convert.ToInt32(tasks_dr.Field<Int64>("MaxOccurrences"));

Pattern.MonthOfYear = Convert.ToInt32(tasks_dr.Field<Int64>("MonthofYear"));

Pattern.DayOfMonth = Convert.ToInt32(tasks_dr.Field<Int64>("DayofMonth"));

System.DateTime? RecursUntil_d;

if (tasks_dr.Field<String>("RecursUntil") != "")

{

RecursUntil_d = Convert.ToDateTime(tasks_dr.Field<String>("RecursUntil"));

}

else

{

RecursUntil_d = DateTime.Now;

}

Pattern.RecursUntil = RecursUntil_d;

appointment.RecurrenceRule = new RecurrenceRule(Pattern);

The Datasourc is an DB which is filled by Datas from an new created Appointment with all values.

Table:

cid      name               type        Value
------- ----------------- ---------- ---
0        id                 INTEGER     n
4        Subject            TEXT       Test
5        Body               TEXT        Test
6        Betreuer           TEXT       69001
7        Startdatum         TEXT      19.04.2012 08:00:00
8        Enddatum           TEXT      19.04.2012 15:00:00
9        Kategorie          TEXT        Fertig
10       Importance         TEXT      Low
11       Ganztag            INTEGER 0
12       Frequency          TEXT      Weekly
13       DayofMonth         INTEGER   0
14       DayOridnal         INTEGER     0
15       MaxOccurrences     INTEGER 0
16       DaysofWeekMask     TEXT Thursday
17       RecursUntil        TEXT        28.04.2012 15:00:00
18       MonthofYear        INTEGER 0
19       TimeMarker         TEXT        Normal
20       FirstDayOfWeek     INTEGER 1
21       Interval           INTEGER 1

But i get an Error in the Schedule.xaml on InitializeComponent - ArgumentOutOfRangeException
The added or subtracted value results in an unrepresentable DateTime.
Parameter name: value

SeriesMapping ItemsSource Redraw/Flicker problem

Hi,

With the addition of the ItemsSource on a SeriesMapping we were finally able to extend your chart control to support binding to multiple collections in an underlying view model.

This is great, and has helped the chart control to start to become viable. However, it seems that every time a new data point is added to the collection bound to a SeriesMapping.ItemsSource, the entire series redraws.

This is with AutoRange set to false for both X and Y Axis and Min/Max values set for both. I can watch the chart, and while the scale never changes, each series blanks out and redraws with each new data point.

Is this fixable with the current release?

Adding custom distinct values

Within DistinctValuesLoading(), I added 3 new strings to distinct values: [2], [4] and [6].
Their purpose is to filter by length, e.g. [2] should only show rows that have a string of length 2 in this column.

Is their any way to achieve this in Filtering() event ?
Or is their another way to reach my goal ?

Formatting not applied the first time the window is displayed

My application is built in WPF. I have a class called "MyWindow" that descends from the WPF Window class. I have another class called "MyDialog" that also descends from the WPF Window class. These two classes have a uniform look and functionality so it made sense to create my own base classes for the applicaiton. The application is to be used on touch screen equipped laptops in police cars, so I've made everything bigger, to make it easier for people with large fingers to interact with the application.

My application has a login dialog that descends from the MyDialog class. During program startup, the application performs a number of steps, including loading a resource dictionary that contains brushes that are used to draw the application's controls. Again, part of the whole unified look.

The login dialog has a RadComboBox on it. The app.xaml has a custom template for RadComboBoxes that increases the width of the drop down button on the control. The first time the login dialog is displayed, however, this template is not applied; the drop down button is the normal width. However, if you enter a wrong password & click login, the dialog is redrawn and this time the drop down button is the right width.

Why is the width of the RadComboBox wrong the first time but right the second time, even though every other aspect of the dialog is drawn right the first time? I don't even know what code to include to help you guys help me on this. Any ideas?

Best Practices for using Dynamic Layer

Hi,

After encountering a few performance issues with the Dynamic Layer, would like some clarification on best practices of using the Dynamic Layer.

The following 2 forum posts are from 2010 - http://www.telerik.com/community/forums/wpf/map/working-with-dynamic-layers-and-mapshapereaders.aspx and http://www.telerik.com/community/forums/wpf/map/radmap-dynamiclayer-performance-problem.aspx

I am currently using the below code to only return those geometries which are in the current extents, rather then dealing with this at a fairly low level, does the Dynamic Layer have any of this functionality included?

Many thanks,

Adnan

public void ItemsRequest(object sender, ItemsRequestEventArgs e)

{

IList<SqlGeometry> geometryList = new List<SqlGeometry>();

LocationRect currentRegion = new LocationRect(e.UpperLeft, e.LowerRight);

string sql = string.Format(

"SELECT the_geom FROM Locations WHERE the_geom.STIntersects(geometry::STGeomFromText('POLYGON(({0} {1}, {2} {3}, {4} {5}, {6} {7}, {0} {1}))', 0)) = 1 "

, currentRegion.Southwest.Longitude, currentRegion.Southwest.Latitude, currentRegion.Northwest.Longitude, currentRegion.Northwest.Latitude, currentRegion.Northeast.Longitude, currentRegion.Northeast.Latitude, currentRegion.Southeast.Longitude, currentRegion.Southeast.Latitude);

using (SqlConnection sqlConnection = new SqlConnection(connectionString))

{

sqlConnection.Open();

using (SqlCommand sqlCommand = new SqlCommand(geographicalBoundsSQL, sqlConnection))

{

using (SqlDataReader reader = sqlCommand.ExecuteReader())

{

while (reader.Read())

{

SqlGeometry sqlGeometry = (SqlGeometry)reader["the_geom"];

geometryList.Add(sqlGeometry);

}

Custom Button Theming

Hi There,

We have a requirement for lots of different buttons with their appropriate look and feel. I have created my own Theme where the buttons would each take on their own style, The required behavior would be to have our own style for each of the buttons, however, if one of your themes were chosen, then it would just use that for each Button Style,

The buttons all inherit from RadButton, However, When we use our own Theme, the buttons look the way they should in design time. eg ButtonType1 = Green, ButtonType2 = Red, NormalRadButton = Orange. However, when I then run the application all the buttons change to the NormalRadButton of Orange. This would be the required behavior when using a Telerik theme.

I have a small demo app that shows the behavior, however, you don't seem to allow these type of uploads, I have attached screen shots of the demo app,

I could send you the demo app if required

Thanks,

Yuri

Facing Error "Missing reference" for the telerik.windows.controls.dll while upgrading the dlls

Hi,

I am facing a problem when I am trying to upgrade the telerik binaries from version "2009.3.1314.1030" to "2012.1.326.1050". I have added the reference of the assembly "Telerik.Windows.Controls.dll" in my project and after that the statement
using Telerik.Windows.Controls ;

is throwing an error like the below:
The type or namespace name 'Telerik' could not be found (are you missing a using directive or an assembly reference?)

I have .net framework 4 installed on my machine.

One other interesting thing that I have observed is that when I have tried to open this assembly in the Object Browser from Visual Studio 2010, it is not opening the assembly.

Any suggestions/ideas to fix this issue?

Thanks,
Vijay
