I have a DateTimePicker with InputMode="DatePicker" and TodayButtonVisibility="True".

If I set the SelectableDateEnd property to DateTime.Today (for a date of birth field for example), I can select today's date in the calendar but the Today button is shown disabled. It seems the time of day is taken into account because if I set SelectableDateEnd to DateTime.Now.AddMinutes(5), the Today button remains enabled until 5 minutes have elapsed. I don't know if this is intentional, but it certainly seems inconsistent. 

I have a radgridview combined with a raddatapager. The data is loaded on demand.

The problem i have now is if i have more then 1 page and i click on the column header for sorting i get a threading exception.

How can i fix/bypass the error?

Hi,

I want to set background color of mu autocompletebox as attached file correctback.png but after focusing on autocompletebox it changes background color to default one. So can you please tell me how I can stop changing background color of autocompletebox on set focus to remain same as on lost focus.

A couple of years ago I've created a custom GridViewCell Template that allowed me to set a custom border inside a cell.
All I had to do was change the BorderBrush and BorderThickness properties of the GridViewCell's style.

But since I've updated to a newer version of the control, this has stopped working. Now the left border is missing.
In the past I've had trouble with the bottom border but setting bottom margin to 1 solved that.
However changing the left margin doesn't fix the visibility of the left border.

This is the original custom GridViewCemm Template:

An example of how I used this:

My previous version of the the control was: 2016.3.1024.45 Here the cell had a perfect border of thickness 2 all-round.
Current version: 2018.1.220.45 Here the left border is missing, the other borders are working fine.

I've tried several things but simply can't get it to work any more.

hello, I m ashrul

please help me, i cant binding RadRichTextBox and RadListView in my viewmodel, i m using data TxtDataProvider,
that i want is when i type in radrichtextbox and so do RadListView items, please help me guys.

Hi, I'm attempting to use the following example to read in my XML:

https://docs.telerik.com/devtools/wpf/controls/radtreeview/populating-with-data/data-binding-to-xml

I am finding that when I convert my items to an ObservableCollection, no results are returned.

My XML is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<DocDef Filename="X">
  <DocVars Selected="yes">
    <DocVar Name="JobNumber" Value="0000" Selected="yes"/>
    <DocVar Name="ProjectID" Value="0000" Selected="yes"/>
  </DocVars>
  <DocContent Name="Requirements" Selected="False">
    <DocContent Name="Meeting" Selected="True" />
    <DocContent Name="Quality" Selected="True" />
    <DocContent Name="OHS" Selected="False">
      <DocContent Name="Another thing" Selected="False"/>
    </DocContent>
  </DocContent>
  <DocContent Name="Footer"/>
</DocDef>

And my associated XML serialization:

    public class GenericNode
    {
        [XmlAttribute("Name")]
        public String Name { get; set; }

        [XmlAttribute("Selected")]
        public String Selected { get; set; }
    }

    [XmlRoot(ElementName = "DocDef")]
    public class DocDef : GenericNode
    {
        [XmlArray("DocVars")]
        [XmlArrayItem("DocVar", Type = typeof(DocVar))]
        public List<GenericNode> DocVarItems { get; set; }

        [XmlElement("DocContent")]
        public List<DocContentValue> DocContentItems { get; set; }
    }
    
    public class DocVar : GenericNode { }

    public class DocContentValue : GenericNode
    {
        [XmlElement("DocContent")]
        public List<DocContentValue> DocContentItems { get; set; }

    }

My issue arises when attempting to extend DocDef as an ObservableCollection<GenericNode> and adding the "AddRange" function:

[XmlRoot(ElementName = "DocDef")]

public class DocDef : ObservableCollection<GenericNode>

{

    public void AddRange( IEnumerable<GenericNode> range )

     {

        foreach (GenericNode node in range)

        {

            this.Add( node );

        }

    }

    ...

If I follow through the rest of the example, AddRange does not add any elements:

public class RadTreeViewXmlDataSource : DocDef
    {
        private string source;
        public string Source
        {
            get
            {
                return this.source;
            }
            set
            {
                this.source = value;
                AddRange( RetrieveData( Application.GetResourceStream( new Uri( value, UriKind.Relative ) ).Stream ) );
            }
        }
        private DocDef RetrieveData( Stream xmlStream )
        {
            XmlSerializer serializer = new XmlSerializer( typeof( DocDef ) );
            StreamReader reader = new StreamReader( xmlStream );
            DocDef list = ( DocDef )serializer.Deserialize( reader );
            return list;
        }
    }

Any help would be very much appreciated!

Background:

I have a RadRickTextBox with the following initializiton and I have set AutoInsertHyperlinks="True" in XAML.

When I run the code google.com is not "hyperlinked". However, if I move cursor to end of hyperlink and press ENTER, hyperlink is recognized.

Question:

How can I force radRichTextBox to recognize hyperlinks when I insert a string? I have tried UpdateEditorLayout etc but no luck.

Hello,

We are evaluating Telerik controls for one of our requirements, where we need to use Tile view control. Each tile contains different controls like Datagrid / charts etc..

Our first requirement is, we want to adjust tiles in a such a way that, in the first row have one large tile, in the second row there would be 4 small tiles and in the third row would he two medium size tiles. For more details on how that should look, please refer attached screenshot.

We found a link: https://github.com/telerik/xaml-sdk/tree/master/TileView/RestoredTilesToSpanMultipleRowsAndColumns 

which can help us to arrange the tiles the way we want. Now we also want those tiles to be resizable and here I am facing difficulties to achieve this. Basically, we are trying to achieve behavior near to this: https://strml.github.io/react-grid-layout/examples/0-showcase.html

Could you please help me out to achieve this requirement. 

Looking forward to hearing you soon.

Thanks,

Parthiv

I have a LayoutControl which contains LayoutControlExpanderGroup-Controls.

The LayoutControl's vertical space is set to a certain height but the content overflows that. As a result, a scrollbar is displayed - which is the desired behavior.

The problem is that when the mouse pointer is over the content of a LayoutControlExpanderGroup control, scrolling with the mouse wheel does not work anymore.

When the mouse pointer is over the header of a LayoutControlExpanderGroup, it works though.

I guess the Scrollviewer in the LayoutControlExpanderGroup control "steals" the mouse wheel event? Is there any way to fix that behavior?
