Hello,

I have some of GridViewCheckBoxColumn and GridViewComboBoxColumn that bound to nested property which works perfectly. But when I try to use ExportToXlsx() to export into excel file, result from every columns that bound to nested property are different.

GridViewCheckBoxColumn bound to nested property yields True/False instead of TRUE/FALSE and GridViewComboBoxColumn yields selected value instead of display value which I preferred display value.

Is there anyway to make all columns regardless of nested property binding to be exported in the same format?

Here's my sample code

Thanks

Hi,

I have a huge amount of data, which I don't want to load all into the gridview.

I want to have the following scenario: The user applies filter with the default filtering control. The ViewModel get the FilterDescriptor and request the filtered Data at the DataService. The GridView shows the received data.

I don't want to use the filter for filtering the data bound to the gridview, I want to use it to request filtered data.

I've modified the AppointmentItemHorizontalControlTemplate template to include a popup like so:

The popup shows as expected, however when I try to selected something on the popup by holding down the left mouse button, a drag effect is initiated beneath it that is trying to move the appointment into another slot (e.g when using the Month View definition). Unfortunately no event is received in the popup until after the drag effect is initiated.

Is there are a way to cancel the drag effect of the schedule view when the user is interacting with a popup?

now the fluent theme use the Aero effect,the background is too clear,

the Acrylic effect is better!

there is a opensource project: https://github.com/sourcechord/FluentWPF

the principal code:

     internal enum AccentState
    {
        ACCENT_DISABLED = 0,
        ACCENT_ENABLE_GRADIENT = 1,
        ACCENT_ENABLE_TRANSPARENTGRADIENT = 2,
        ACCENT_ENABLE_BLURBEHIND = 3,
        ACCENT_ENABLE_ACRYLICBLURBEHIND = 4,
        ACCENT_INVALID_STATE = 5
    }

   accent.GradientColor = 0x00FFFFFF;

Hello,

A multi-selection RadComboBoxis integrated into a cell of a RadGridView in the project that is attached.

The problem I have when trying to add a handle to an event to customize the loading of the multiple values of the RadComboBox.

This code does not work ...

FrameworkElementFactory dateFactory = new FrameworkElementFactory (typeof (RadComboBox), "Target");
dateFactory.SetValue (RadComboBox.AllowMultipleSelectionProperty, true);
dateFactory.SetValue (RadComboBox.ItemsSourceProperty, new List <string> {"DBF", "REP"});

                 // Add handler not rule
                 RoutedEventHandler handler = new RoutedEventHandler (LoadedTarget_RadComboBox);
                 dateFactory.AddHandler (RadComboBox.LoadedEvent, handler, true);


On the other hand, if I add the handler outside of a Grid it works correctly

Thanks in advance.

[I'm attaching the test project code concerning the problem]

we are using 2 RadTreeview in of our form in WPF application.

How can I force data-grid refresh on the Outlook Template for VS2018?

At this moment, when I make a change on the cell, I need to close the group and open the group to see the changes.

I am using observablecollection and INotifyPropertyChanges.

I saw in some forum that I can force the grid to update, I want to do this with a button which calls on a command function from the command file in the template.

e.g.   DataGridName.Item.Refresh();

But it seems like I can't find the reference to the datagrid at all.

Is there a way to have the Search box selected when a window with RadGridView is initialized? I want the user to be able to search straight away, without having to first click on the search box to enter text.

Hi Telerik,

I'm working with your outlook inspired template for VS 2018 and is a bit stucked. 

For the moment, the data in the data-grid seem displays the data from the outlook section.

My problem is: I want the data in the data-grid to be displayed independently from the outlook section, which means, that by removing the outlook section, the data in the data-grid should not disappear.

What is the easiest way for me to achieve this, without breaking functionality like hasSelected unread/read?

However, the data I want to display is the exact same emails created in the SampleContentService, I just don't want to bind the data-grid to these folders in the outlook sections. 

Thanks

Hi,

How can I change ItemsSource in the outlook template?

At the moment, it seems like the e-mails shown in the data-grid is retrieved through the Outlook Section. 

How can I bind data independent of the outlook section? Because I'm thinking of removing the OutlookBar and OutlookItem (Panel of the left side), and this makes the e-mails from the data-grid disapp

        private static ObservableCollection<ContractGroup> _contractGroup;

        public static ObservableCollection<Contract> GetContracts(int size, string keyword)
        {
            var contracts = new ObservableCollection<Contract>();
            for (int i = 1; i <= size; i++)
            {
                XamlFormatProvider xamlFormatProvider = new XamlFormatProvider();

                contracts.Add(new Contract() { Symbol = test
            }

            return contracts;
        }

I want to retrieve the contracts,directly from the SampleContentService, how can I do this?
