Hello

I would like to know how I could fill all empty space in a RadRibbonTab with a RadRibbonGroup.

hello, i am trying to replace my radchart with a radchartview,
but i stumble on this problem  : the lines connecting my values are not drawn ( using line series)
( i am using a DateTimeCategoricalAxis because i only want ticks for dates with actual records in my itemsource,
and don't need the distance between 2 values to be an indication of the time between, the production environment wil have multiple values on some day, and none on others, but i dont think is the cause of my problem   )
( screenshot to show the resulting window)
viewmodel :
public class ViewModel
{
public ViewModel()
{
List<TestItem> items = new List<TestItem>();
for (int i = 1 ; i< 20; i++){
var r = new TestItem();

r.Datum = DateTime.Now.AddDays(-1 * i * i /** 10 / 3*/);
if (( i % 2) == 0){
r.Waarde1 = DateTime.Now.Second / i;
}
if ((i % 3) == 0)
r.Waarde2 = DateTime.Now.Millisecond / i;
if ((i % 5) == 0)
r.Waarde3 = DateTime.Now.Second;
items.Add(r);
}
Items = items;
 }
public List<TestItem> Items { get; set; }
}

public class TestItem {

public DateTime Datum { get; set; }
public decimal? Waarde1 { get; set; }
public decimal? Waarde2 { get; set; }
public decimal? Waarde3 { get; set; }

public override string ToString()
{
return string.Format(" {0:d} : {1} - {2} - {3} ", Datum,Waarde1,Waarde2, Waarde3);
}
}

Can some please help me, I cannot seem execute a delete operation when one item is inside my observable collection and binds to the RadDataForm, however when I bind 2 or more items I can  then perform delete up until one item remains then “CurrentItem” is null. why is that ???

The offending snippet takes place here.  

I am attempting to use a GridView to display the contents of a delimited file.  Initially the application reads the 1st 20 lines of the file and displays these in a single column with one row per line.  The user then selects the field delimiter to use to parse the rows into columns.

My problem is when the 1st 20 rows are displayed only the first character from each row is displayed in the single column of the GridView;


I have confirmed that "csvImport.GetLine" is returning a single line from the text file (anything from ~400 to ~1500 characters) and that these are added correctly to the ObservableCollection.

How can I get the GridView to display the entire string for each row?

Thanks in advance for any help anyone can provide.

Hello.
I have an application view that allows user to switch between several pages.
In one view there are a ListBox and a ComboBox which used for a grouping selection.
Items for a ListBox are being added using Timer every several seconds no matter which view is selected by user.
So, when user selects view with grouping ComboBox, chooses grouping value and then switches back to another view and then again switches to the view with grouping the program raises NullReferenceException (if you try to select anyting in ListBox or try to change grouping value).
I gave a link to the sample project that demonstrates the problem.
https://www.dropbox.com/s/3flf3woe5ba76d1/WpfApplication1.zip?dl=0

Is there any workaround?

P.S. If I use standard Visual Studio ListBox no exception is thrown. It gives an error only when RadListBox is used.

Thank you for the help.

Hello,
I've been working last days on a demo with RadDiagrams...and I've almost reached my goal... I just need a few help on containers....

I've created via code some different containers based on a level I had


I've set in my view the TreeLayout as TreeLeft as (http://www.telerik.com/help/silverlight/media/raddiagram-features-layout-tree-left.png)

and I have a container for each level.... I wish to have all the container aligned horizontaly but actualy it displays as the image I've attached

How do I tell the container to set the items vertically?
Ho do I align the containers horizontaly?

Thanks in advance

Hi,
 
I require a control that would accept input in the form : 2 w 3 d 5 h 6 m. User should be able to input the values before d, w, h and m ( which represents weeks, days, hours, minutes). Is it possible to use MaskedInput to achieve the same. w,d,h and m should not be editable. How can I implement that?

Thanks,
Divya

I'm not sure how to make this happen, but the treeview starts going up and down like crazy.
