Hi guys, 

I need to make StrokeThickness bigger for the relation of the selected tasks.  What I want is to make easier for the user to understand each task's dependencies.  How can I do it?

Best regards

Hi,
I need to implement a grid where the user can select a list of itemes from a TreeView. Once the items are selected, the cell must show the concatenation of selected items. Attached you can find a sample screenshot of what I need.

I tried to do that creating a custom column (https://docs.telerik.com/devtools/wpf/controls/radgridview/managing-data/how-to/howto-create-custom-editor). 
This is an extract from the code of my custom column.

public override FrameworkElement CreateCellEditElement(GridViewCell cell, object dataItem)
        {
            var treeView = new RadTreeView
            {
                IsOptionElementsEnabled = true,
                ItemsSource = TreeViewItemsSource,
                ItemContainerStyle = TreeViewItemContainerStyle,
                ItemTemplate = HierarchicalItemTemplate,
            };

            var dropDownButton = new RadDropDownButton
            {
                DropDownContent = treeView,
                DropDownMaxHeight = 250,
            };

            //this.BindingTarget = ???;

            return dropDownButton as FrameworkElement;
        }

My question is how to bind the checked items of the TreeView to the BindingTarget dependency property of the GridViewBoundColumnBase in order to update the field of the data item bound to the column, once the cell edit is committed.

Thanks in advance.

Dear,

Binding 'Header' property to DataContext in a GridVewColumnGroup doesn't work. Public property is not requested to DataContext.

    <telerik:GridViewColumnGroup Name="RangeColumn" Header="{Binding FirstDependencyName, FallbackValue=Nothing}" />

By other hand, a binding to StaticResource works property.

    <telerik:GridViewColumnGroup Name="RangeColumn" Header="{Binding Source={StaticResource appResx}, Path=btn_Create}" />

In next example, public property is requested to DataContext (value is received tested with a converter), but surprisingly it is not displayed.

    <telerik:GridViewColumnGroup Name="RangeColumn">
        <telerik:GridViewColumnGroup.Header>
            <TextBlock Text="{Binding FirstDependencyName, FallbackValue=Nothing}"/>
        </telerik:GridViewColumnGroup.Header>
    </telerik:GridViewColumnGroup>

I'm noticing that if I include a space in my search term it treats that as two search items, when I want it to just treat it as one long string.  Is it possible to have the search function this way?

For example, let's say I have the following items in my MultiColumnComboBox.

• Big Dog
• Big Cat
• Big Lemur

If I type 'Big Lemur' in the text box, it doesn't narrow down my search to just Big Lemur.  All 3 are matches.  It appears to be searching on each word in my search phrase.  I think I understand the difference between the different AutoCompleteMode settings, but none of them treat a multi-word search term as just one search value.

Having a weird issue with the calendar popup in DateTimePicker.  I previously had a bug in my date/time parsing algorithm where it was taking years in the present or near future (2018-2025) and parsing them as 1918-1925.  When you go in and attempt to fix this through the calendar control, you can't seem to correctly navigate to the 2000's.

Upon picking the 2010-2019 option in the first screenshot, it then takes you to the 1910-1919 collection.  In this case, the control's SelectedValue is being bound to a Nullable<DateTime> with the date already set before form initialization.  The property and object both implement the INotifyPropertyChanged interface/pattern.  As you can see, the calendar uses the Windows8Touch theme.

Thanks for any guidance that can be provided.

Hello,

Can anyone help by answering on question: Why using this code MapEllipse shape didn't show on RadMap InformationLayer>?

Hi all,

I am on win7 and I tried install the WPF demo by clicking the "demo" button. After downloading "stepup" on "https://demos.telerik.com/wpf/?utm_source=tcp", it returns the error "an error occurring trying to download https://demos.telerik.com/wpf/wpfdemo_application".

Any suggestion? Thanks.
