CandleStick. Not displayed (not drawn) changes within the candles.

I can not understand how to solve the following problem: There is real-time chart of Security.

<



<telerik:RadCartesianChart x:Name="chart" Grid.Column="0"    >
                <telerik:RadCartesianChart.Grid>
                    <telerik:CartesianChartGrid MajorLinesVisibility="Y"/>
                </telerik:RadCartesianChart.Grid>
 
 
                <telerik:RadCartesianChart.Behaviors>
                    <telerik:ChartCrosshairBehavior/>
                    <telerik:ChartPanAndZoomBehavior DragToZoomThreshold="0" MouseWheelMode="Zoom" DragMode="Pan" ZoomMode="Both" PanMode="Both"/>
                </telerik:RadCartesianChart.Behaviors>
 
                <telerik:RadCartesianChart.HorizontalAxis>
                    <telerik:DateTimeContinuousAxis x:Name="AxisX"  LabelFormat="HH:mm" LabelFitMode="Rotate" SmartLabelsMode="SmartStep" PlotMode="OnTicksPadded"  />
                </telerik:RadCartesianChart.HorizontalAxis>
 
                <telerik:RadCartesianChart.VerticalAxis>
                    <telerik:LinearAxis MajorStep="1" LineThickness="1" SmartLabelsMode="SmartStepAndRange" />
                </telerik:RadCartesianChart.VerticalAxis>
 
               <telerik:CandlestickSeries  ItemsSource="{Binding Candls}" CategoryBinding="Time" CloseBinding="Close" HighBinding="High" LowBinding="Low" OpenBinding="Open" DefaultVisualStyle="{DynamicResource #CandleStickStyle}" />
 </telerik:RadCartesianChart>

public ObservableCollectionEx<Candle> Candls = new ObservableCollectionEx<Candle>();

New candles appear immediately. Change the "Close" is not displayed in the candle when changes occur between the extreme values of the "Close". in a stream of data received and the change correctly. This can be seen on the grid.

I tried to delete data from the collection of the last candle and insert new data, not to make changes to existing ones. The result remained the same :(

How can I display all the changes in the closing candle?

RadGridView Vertical Scrolbar Thumb position, length and display data

Hi All,

i am using the radgridview control, added the custom filters to it successfully and all the default styles are working great. i have a requirement of infinite scrollbar and display row number on thumb. so i implemented the Data Virtualization but that did not match my requirement, in this the VirtualItemCount has to be set initially(when i tried to set it dynamically all rows data is empty no data is visible in the grid) more over the VirtualQueryableCollectionView maintains its own collection and its like a copy which i don't want. so with the MVVM pattern via observablecollection iam populating the data into the grid and this collection has constant size. now while scrolling when i reach to end of the scroll in the scrollchanged event iam replacing the collection with new data. all this is working but w.r.t this i also need to change the scrollbar's thumb as like inifinite scroll. i had written code to adjust the scrollbar thumb position, length nothing is working. Another issue is like displaying the record number on the thumb i had added the xaml code in style but when i apply the style the gridview is gone, it is not displayed. not sure what is the correct way of displaying the data on the thumb without losing the all default radgridview style.

Anyone please guide me.

Selection triggers multiple actions

Hi,

At the moment I have an autocomplete box which opens another tab. The autocompletebox list overlaps Tiles, when a selection is selected that overlaps a tile, it'll trigger the selection event AND the tile event. May I ask how do I set it up such that it'll only trigger selection event.

HTML data provider not triggered upon pasting

Hi,

I currently implemented an intercept, such that when the paste command is triggered, it'll create a stream of the image and upload to s3 and then delete that image and paste an inlineimage of that now resides on S3. The richtextbox is not then converted to html immediately upon paste action, if I hit any key strokes then it'll be converted. Is there any manual way of triggering the htmldataprovider, maybe call that function or do a dirty trick such as enter in key then delete key.

Cant clear filter

I have a radgridview and a Command to save changes to that view on a button next to it

<Button Content="Save" Margin="0, 0, 8, 0" Command="{Binding Path=SaveAndNewCommand}">

<Button.CommandParameter>

<Binding ElementName="Registrations" />

</Button.CommandParameter>

</Button>

When I save I want to clear any filters on this RadGridView

So in my Command I fire this in my UI thread when I am done

radGridView.FilterDescriptors.SuspendNotifications();

foreach (GridViewColumn column in radGridView.Columns)

{

column.ClearFilters();

}

radGridView.FilterDescriptors.ResumeNotifications();

I also tried

radGridView.FilterDescriptors.Clear();

but nothing seems to work, the lines aint filtered, but the filter button still shows the filtered state, and if I click on the filter icon, any settings I had before are still set.

[Solved] Title: Place holder tag in rich text document.

Is it possible to add a place holder tag to a rich text document? As for example, it might look like this
<t:section>
<t:paragraph>
</t:paragraph>
<custom:Placeholder />
<t:paragraph>
</t:paragraph>
</t:section>

And in this case, telerik will just ignore the place holder tag and load the document ignoring them. All the document operation will be performed ignoring the place holder tag.
This is kind of feature or behaviour available or possible?
