Custom Tick Bar

Hi,

Is there a control for just displaying the tick marks (with labels) that you would normally see attached to a slider control? I was hoping RadTickBar would do it, but the documentation doesn't seem to elaborate on whether it's possible to use it on its own or not.

Expander Header Cursor

Hi,

I'm using the RadExpander as part of the RadControls collection (RadControls for WPF Q3 2011 SP1) and I'm trying to get the cursor to change to the Hand icon whenever the user hovers the mouse over the header part of the Expander control.

I know I can simply use:

<

telerik:RadExpander IsExpanded="True" Cursor="Hand">

...but this shows the Hand icon over all of the control. What I'm after is the icon to change when the mouse is only over the Header part of the control, i.e. the part which the user can click to fire the expand/retract animation. Is this possible?

Thanks!
Mike.

[Solved] Using one datasource

Hi Everyone

Is it possible to use only one DataTable as a DataSource to create a treeview.
Basically there will be two keys in the table, the first key will be the primery key and the second key(Parent Key) will tell the column to which primery key it should link too.

Somthing like this

Prime Key    Parent Key    Item
1                  null                Car
2                  1                    Tyre
3                  1                    Fuel
4                  2                    Rims
P.S. Null, means it's not linking to anything and it will be the first item(Node) in the tree

If it's possible, can someone give me an example?

Regards

BarSeries Data is invisible?

In an effort to create a Histogram chart, I was instructed to use a BarSeries by someone on this forum, and set it's CategoricalAxis.GapLength to 0.000001 (can't set to 0 because of a known bug). After doing this, I created a BarSeries and set it's data to what I thought would correct. I can see the y axis growing at the correct rate, but there are no bars visible!

Xaml:

<telerik:RadCartesianChart x:Name="RadChart1" Palette="Metro" HorizontalAlignment="Right" VerticalAlignment="Top" Width="1000" Height="400">

<telerik:BarSeries ItemsSource="{Binding Data}" ValueBinding="Data"/>

<telerik:RadCartesianChart.HorizontalAxis>

<chartView:CategoricalAxis MajorTickInterval="250" GapLength="0.00001"/>

</telerik:RadCartesianChart.HorizontalAxis>

<telerik:RadCartesianChart.VerticalAxis>

<telerik:LinearAxis LabelFormat="0"/>

</telerik:RadCartesianChart.VerticalAxis>

<telerik:RadCartesianChart.Grid>

<telerik:CartesianChartGrid MajorLinesVisibility="Y" />

</telerik:RadCartesianChart.Grid>

</telerik:RadCartesianChart>

The data is formatted in an ObserveableCollection<ChartData> as defined here:

public class ChartData

{

public int Index { get; set; }

public int Data { get; set; }

}

(I'd previously used this format for a ScatterSeries with no issue)

The graph is growing, but it's like there is no default style applied to the BarSeries, thoughts?

Not sure when to use

I would like to persist a RadGridView for visibility and order of columns per user between sessions. The GridView is on a User Control that is added to a RadTabControl at startup via Prism's RegionManager. This UserControl/TabItem doesn't get removed from the TabControl until the application closes.

When (which events) is the best time to load and save?

Trouble with Icons

What is the recommended size for the reg and small icons for the outlookbar? I'm using 16x16 png and it looks fine except when I minimize the outlookbar. Then apparently the icon isn't big enough so a tiny bit of the text shows. I've tried using png in 24x24 size, but then they look all messed up. You can see what I mean in the attached image. I tried making the minimized width smaller so that it wouldn't show the text, but then the button at the top (for expanding) was cut off.

Can you tell me the proper image type and size?

[Solved] Ichimoku shading

Is there a built-in way or could anybody point me to the right direction to go about creating Ichimoku cloud areas in [presumably] RadChart. For clarification, there's essentially two line series, one green, one red. When the red one's higher, the area between the two is highlighted red, when the green one's higher the area between's highlighted green.

Text version follows; R = red line, r = red shading, G = green line, g = green shading

RRRRRRRR                                                               GGGGGG
rrrrrrrrrrrrrrrrrRRRRRRR                               GGGGGgggggggg
rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrRR               GGGGggggggggggggggg
rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrRGGGGgggggggggggggggggRRR
rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrGGGRggggggggggggggRRRRR
GGGGGGGGGGGGGG           RRRRRRRRRRR

Any help/pointers will be much appreciated.
