Hi there,

a lot of guys are right: it seems to be neccessary to wait for the first service pack of a new Telerik version. :-(

This was the same procedure with ANY new version in the past... this is not a very good recommendation for the QA at Telerik, I guess.

You should not favor QUANTITY over QUALITY. It is very, very frustrating to find several new bugs in *existing controls* in every new release of the controls and to wait for the service pack for several weeks.

We tested the new 2012.1.0215 version in our current project (it uses several WPF controls from Telerik). And after some minutes of testing, we found 4 really severe bugs. Basic stuff, which worked totaly fine the 2011.3.1220 version...

So we had to switch back again (as allways).

Look at DevExpress (I worked with their controls for years in the past): they seem to have a much better QA than Telerik. I never had such problems with new bugs in new versions of WPF/WinForm controls at DevExpress.

Come back to QUALITY and good QA, guys! Your customers want to have stable and bugfree controls. Invest more in QA of existing functionality instead to produce more and more fancy controls for the kids in the block!

A very frustrated customer.

RadCarousel autosize to fit image

Hi,

in my WPF project, I fill dynamically images to a RadCarousel. I bind the ItemsCource to a List<Image> variable. I would like to know how I can specify to the carousel to strech all images to take maximum space available space keeping their aspec ratio.

Actually, I have a small carousel with thumbnails, when a user the click on an image, I take all related images and then, transfert it into another window with a bigger carousel. The problem is, most of the images are bigger than the height of the screen resolution. I would like thoses images to shrink into the display area to prevent loosing details on the image. I need the smaller images to grow to maximum size,

Thank's

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.

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?
