Is it possible to customize the xaxis labels?

Hi,

I have two major problems - one is partial solved via setting IsLabelRotated to false.
The other is really a problem and I couldn't find anything in the documentation.

First of all -- is it possible to rotate all labels "Inside out".
Your kind of "auto rotation" is quite a bit irritateing :)

What I get - on a scale 0 - 100 with 10 is.
0, 10, 20 is "outside in" 30 to 70 is "inside out" and finally 80, 90 and 100 is again (in the oposite direction)
"outside in".
What I simply want is all inside out -- like with the radial (first) here http://www.david-black.info/bashboard/default.aspx

BUT: without rotation it is not exaxtly what I want - but at least "readable" - so not that problem.

The second thing is much more imporatant.
I display a value in the range from 0 to 255.
So it would be nice to have labels at 0, 20, 40, 60,....200, 220, 240, 255
All I found was "MajorTicks" which give me labels like 21, 43, 64... with 12 as value,
or 26, 51, 77... and so on if I keep the default of 10.

I was looking for something like "TickDistance" or "TickFrequency" -- but all I found was "MajorTicks"
which is an integer divider -- not really usefully for numbers like mine.
Of course it would work with 260 - and 13 --- but my users would be a bit irritatied if a display for an 8 bit A/D converter
shows number bigger than 255 :)

Waiting for you help

Hi,
   I am using expanded event of the WPF Treeview to populate children of the parent node when the parent node is clicked.

I am binding my treeview with the collection. Collection has 2 things
a. Name
b. Commodity

On page load:

this

.RadTreeView.Items.Add(new RadTreeViewItem()

 

{

Header = "Name"

 

});

 

this.RadTreeView.Items.Add(new RadTreeViewItem()

 

{

Header = "Commodity"

 

});

Now I want to show the children under commodity on click of commodity (parent node).

 

private

void RadTreeView_Expanded(object sender, Telerik.Windows.RadRoutedEventArgs e) { 

 

 

 

 

 

RadTreeView objRadTreeView = sender as RadTreeView;

 

 

 

RadTreeViewItem objRadItem = e.OriginalSource as RadTreeViewItem;

 

 

 

CommodityCollection objCommodityCollection = this.CommodityCollection;

 

 

 

 

for (int i = 0; i < objCommodityCollection.Count; i++) {

 

 

 

 

 

 

objRadItem.Items.Add(

objCommodityCollection[i].CommodityName);

 

 

 

    }
}

 

Now the issue is when I run the application, as currently there are no child for commodity I am not getting expand icon on the left side of commodity (when the page is loaded) because of which Expanded event is not called.

How to resolve this issue?

 

 

 

Hi,
   I have seen the demo of load on demand in your site but it uses Expanded event. There is event called LoadOnDemand in treeview, so my Question is how can we use this event to load child nodes on demand.

Also when I use Expanded event how will I know which parent node is been clicked .

 

private void RadTreeView_Expanded(object sender, Telerik.Windows.RadRoutedEventArgs e) {

 

 

    RadTreeView objRadTreeView = sender as RadTreeView;
}

 

Hi,

since we had a lot of problem with your gauge (missing documentation as first thing) we decided to use other gauges in our silverlight applications.
We choose Dave's Silverlight Dashboard. (http://www.david-black.info/Bashboard/Default.aspx)
The reason - free including sourcecode.
AND - most important - it takes only a few line of XAML to get a nice looking gauge.
These work fine - but only for silverlight.

Your controls (I guess from reading) have the same codebase for Silverlight and WPF.
So since we would need your controls primarily for WPF I ask in this forum.

The above noted controls allowe two-way data binding.
http://www.david-black.info/Bashboard/Extras/Bidirection.aspx

Do you (in the near future) also think about implementing two way binding?

I see there are descriptions in the docs/examples on how to do a programmatic initial sort. Is there a way to do a declarative initial sort?
I can't seem to get that to work.

I have a collection which contains two properties
1. ABC
2. XYZ

I want to make XYZ as the child of ABC For example:

.ABC1
    .XYZ1
    .XYZ2
.ABC2
    .XYZ3
    .XYZ4

I want to bind this in .XAML.CS page

Currently what I have done in XAML

 

<Telerik:RadTreeView x:Name="RadTreeView" DockPanel.Dock="Bottom"/>

 

 

In XAML.CS page
Collection is CommodityCollection

RadTreeViewItem

aa;

 

 

 

 

 

for (int i = 0; i < CommodityCollection.Count; i++) {

 

aa = new RadTreeViewItem();

 

 

 aa.Header = CommodityCollection[i].ABC;

 

this.RadTreeView.Items.Add(aa);

Now my problem is How to add child node in the RadTreeView?

 

 

Hi..
What event is fired when the carousel is 'moved' either by MoveBy or using the Horiz/Vertical  scrollbars?
Can the scrollbars be customized?
Thanks again.!

Hi,
I've created a simple solution to test the RadTreeview.It just initializes a new ObservableCollection of Items like this:

and in xaml created a simple HierarchicalDataTemplate:

Now, when I am trying to drag "Item 1" to, lets say, "Item 2" it works ok. But if afterwards I am trying to drag "Item 3" to "Item 1" (that is now under "Item 2") I am getting a NullReferenceException with the following stack trace:

To make things even worse, it's not constant. It happens in about 50% of the tries.
Thank you in advance,
Tal

Just installed WPF with VS2008.
Want to get GridView to work.
I installed the .dlls in the toolbox as described here: http://www.telerik.com/help/wpf/adding-radcontrols-to-vs-toolbox.html

The following is what I pieced together from the online demo:

<Page x:Class="TestGridViewAggregate.Page1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
    Title="Page1">
    <Grid>
       <telerik:RadGridView></RadGridView>
    </Grid>
</Page>

However, it gives me the error:
"The tag 'RadGridView' does not exist in XML namespace clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView'"
