RadDropDownButton User.Click does not work

Hello.

I was writing UI-test for WPF application (using NUnit Framework and ArtOfTests), and in my test I need to click on RadDropDownButton:

 <telerik:RadDropDownButton x:Name="btnDrop">
 <telerik:RadDropDownButton.DropDownContent>
 <telerik:RadContextMenu >
 <telerik:RadMenuItem Header="op1" Command="{StaticResource op1CommandReference}"/>
 <telerik:RadMenuItem Header="op2" Command="{StaticResource op2CommandReference}"/>
 <telerik:RadMenuItem Header="op3" Command="{StaticResource op3CommandReference}"/>
 </telerik:RadContextMenu>
 </telerik:RadDropDownButton.DropDownContent>
 </telerik:RadDropDownButton>

To click on this button, I use the following code:

var button = win.Find.ByName<Telerik.WebAii.Controls.Xaml.RadDropDownButton>("btnDrop");
button.User.Click(MouseClickType.LeftClick);

The test works fine (no exception have been thrown), but RadContextMenu does not appear.
When I click on this button using mouse, I can see this menu with 3 RadMenuItem items.

How can I solve this problem?

Misaligned TimeTick labels

Hi there,

we are currently developing a wrapper control of your RadChartView RadCartesianChart. In this control we are using a DateTimeContinuousAxis like this:

<telerik:RadCartesianChart.HorizontalAxis>

<telerik:DateTimeContinuousAxis x:Name="dateTimeContinuousAxis" PlotMode="OnTicks" LabelFitMode="Rotate" MajorStepUnit="Second" LabelFormat="HH:mm:ss" FontSize="{Binding AxisFontSize, FallbackValue=14}" />

</telerik:RadCartesianChart.HorizontalAxis>

When changing the AxisFontSize we entirely re-add all Series with new loaded data to get rid of this problem without success. In that process it does not even matter the new data is in a different time range or not. This is happen in design time and in runtime after changing the AxisFontSize of our control:

https://dl.dropboxusercontent.com/u/55589036/Pictures/Animated%20Screenshots/20150326_1440.gif

Besides the AxisFontSize we provide some other DependencyProperties:

· TimeRange to adjust the duration time. When changing the TimeRange we will also re-add everything and generate some empty data to get the desired time span on the X axis.
· TimeTickCount to change the number of time ticks on the X axis. When this is changed we only re-calculate the desired MajorStep value for the DateTimeContinuousAxis.

Combining those three settings together results in strange behaviors with the X axis date time value labels when changing the AxisFontSize in the first place:

https://dl.dropboxusercontent.com/u/55589036/Pictures/Animated%20Screenshots/20150326_1441.gif

Now how can we get rid of it? We already tried to re-add entirely new data in a different time scope. We also tried using UpdateLayout() and InvalidateVisual() in the end of our Update() method that re-adds the series. It seems this is a bug and we cannot find a way to bypass it. As I see you are keeping the old labels even on adding new data plots. This might be useful for resource management, but it disallows us to get rid of this display bug by simply redrawing those labels.

How can we fix it? Or is there a way to force your control to really redraw the labels?

Thank you!

RadRichTextBoxRibbonUI Table Malfunctions

I've noticed that if I have a document with a table in it and am doing MergeFields as well. Whenever I hit one of the buttons to change what the MergeField is showing (Field Codes, Preview, etc.). The ribbon UI immediately switches to the "Layout" tab for the table, even if I am not in the table. After you press the next button once for previewing MergeFields, the issue appears to go away, but to a client using this, it would be rather annoying.

RadMap performance in app with high memory usage

Hi guys,

My app typically uses high amount of memory, up to 1GB in some cases. My machine has 12GB so no problem. However in intensive cases, RadMap fails to respond after panning/zooming for a couple of times. When profiled, the bottleneck is in Telerik.Windows.Controls.Map.TileSource.CreateBitmap(). I tried using cache but not much improvement. Any advice?

<Window x:Class="RadMapPerf.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

Title="MainWindow" Height="600" Width="800">

<Grid>

<telerik:RadMap x:Name="RadMap" Center="38.8993487,-77.0145665" UseDefaultLayout="False" ZoomLevel="7">

<telerik:RadMap.Provider>

<telerik:OpenStreetMapProvider IsTileCachingEnabled="True"/>

</telerik:RadMap.Provider>

</telerik:RadMap>

</Grid>

</Window>

public partial class MainWindow : Window

{

private readonly List<string> _memory = new List<string>();

public MainWindow()

{

InitializeComponent();

// fake memory usage

for (var i = 0; i < 100000000; i++)

_memory.Add("memory_usage");

}

RTL : Brackets get inverted when importing HTML in RichtextBox

Hello,

We are using richtextbox in RTL. We mostly use arabic text and the issue here is that the html which we have has some brackets which render properly when I open the html in a web brower (say Firefox,IE) and also from microsoft word, but when I try to import the same html in RichTextbox the brackets are either reversed or disoriented or not rendered properly. Attached are the sample html to reproduce the issue and the screenshots from word and telerik richtextbox editor.

Title for lines in RadCartesianChart

Hello Telerik Team,

I am trying to use RadCartesianChart with few lines. I displayed the lines on RadCartesianChart and added RadLegend to display line names. But the color is the same for each lines.

So my question is How can I add unique color for every line? Or How can I add title for every line (like attached NamedLines.jpg) with some set of colors (can be repeated)?

Thank you,
Iurii.

GridView context menu not working with header been a textblock

Hi,

I have followed this post from Telerik documentation to show context menu on the radgrid to choose columns of the grid.

http://docs.telerik.com/devtools/wpf/controls/radgridview/columns/how-to/use-radcontextmenu-mvvm.html

But, as we need to wrap header text, we are using textblock for it like below, due to which header text and the context menu items are not in sync. And so, I have ended up writing code in the radcontextmenu events in the code behind file to manually chose columns etc. Just wondering if there is a xaml way to achieve the same even when header text is placed inside a textblock or am I missing anything here?

Thanks,
Lax

<telerik:GridViewDataColumn DataMemberBinding="{Binding Balance, StringFormat=N0}" TextAlignment="Right" >

<telerik:GridViewDataColumn.Header>

<TextBlock Text="Balance prior deductions" TextWrapping="Wrap" Width="100px"/>

</telerik:GridViewDataColumn.Header>

</telerik:GridViewDataColumn>

Force Row Validation Failure on Cell edit update validation failure

Hi,

Is there an elegant way of forcing row validation failure while editing a GridView Cell, and BEFORE databinding takes place?

I have a decimal property bound on an object that is databound to an editable grid column, and I would like row validation to kick in immediately if the value in the cell (which is in edit mode) is not a valid decimal OR if the object bound to the row is not in a valid state.

I specifically want to use Row validation because cell validation only highlights the cell, whist row validation is more prominent because the whole line is highlighted in red as well as there is an exclamation mark on the left of the grid row being validated.

Do you have a good example of validation in a WPF RadGridView that uses MVVM? If there are please let me know.

Thanks for your help.
