I am trying to export filtered records from radgrid.But it was importing all the records those are in my grid.

Please let me know how can i achieve this.here is the code snippet.

 string extension = "pdf";
            rgEquipmentTracking.ElementExporting -= rgEquipmentTracking_ElementExporting;
            rgEquipmentTracking.ElementExporting += rgEquipmentTracking_ElementExporting;            
            SaveFileDialog dialog = new SaveFileDialog()
            {
                DefaultExt = extension,
                Filter = String.Format("{1} files (.{0})|*.{0}|All files (.*)|*.*", extension, "Pdf"),
                FilterIndex = 1
            };
            var grid = new RadGridView()
            {
                
                ItemsSource = rgEquipmentTracking.ItemsSource,
                RowIndicatorVisibility = Visibility.Collapsed,
                ShowGroupPanel = false,
                CanUserFreezeColumns = false,
                IsFilteringAllowed = true,
                AutoExpandGroups = true,
                AutoGenerateColumns = false,
                Margin = new Thickness(30, 30, 30, 30),
                ShowColumnFooters = true,

                EnableRowVirtualization = true
            };
            
            foreach (var column in rgEquipmentTracking.Columns.OfType<GridViewDataColumn>())
            {
                if (column.IsVisible == true && column.UniqueName != "ViewDetail")
                {
                    var newColumn = new GridViewDataColumn();
                    newColumn.DataMemberBinding = new System.Windows.Data.Binding(column.UniqueName);
                    grid.Columns.Add(newColumn);
                    if (column.UniqueName == "ItemDate")
                    {
                        newColumn.UniqueName = "Sign Out Date";
                        newColumn.Header = "Sign Out Date";
                        newColumn.DataMemberBinding.StringFormat = "{0:dd/MM/yyyy}";
                    }
                }
            }


            StyleManager.SetTheme(grid, StyleManager.GetTheme(grid));
            if (dialog.ShowDialog() == true)
            {

                using (Stream stream = dialog.OpenFile())
                {     
                    
                    grid.ExportToPdf(stream,
                        new GridViewPdfExportOptions()
                        {
                            ExportDefaultStyles = true,
                            ShowColumnFooters = true,
                            ShowColumnHeaders = true,
                            ShowGroupFooters = true,
                            AutoFitColumnsWidth = true,
                            PageOrientation = PageOrientation.Landscape
                        });
                }
            }

Hi,

it is easy to create GridView rows by button click. But is it possible to create rows for a month? I want to create
perhaps may. So i need 31 rows and in one column should be the Date from SO 01.05.2016 to  TUE 31.05.2016?

Thanks a lot
Best Regards

So I'm trying to get the ScheduleView to allow a gridview and a listbox drop appointments (ScheduleItems) on it - and I can't seem to get the ConvertDraggedData to work properly because the ListBox sends through an IEnumerable<IOccurrence> and my GridView sends the raw item through (ScheduleItem).

So I rolled my own GridViewDragDropBehaviour class (as there isn't one built in for the GridView) and on the OnDragInitialize event, I'm using IDragPayload.SetData() to set the data to be the raw (ScheduleItem) item.  The ListBox is using the built in ListBoxDragDropBehaviour class.

This is my ConvertDraggedData code:

public override IEnumerable<IOccurrence> ConvertDraggedData(object data)
{
if (DataObjectHelper.GetDataPresent(data, typeof(ScheduleItem), false))
{
    return ((IEnumerable)DataObjectHelper.GetData(data, typeof(ScheduleItem), false)).OfType<IOccurrence>();
}
return base.ConvertDraggedData(data);
}

Obviously when items are dragged from the GridView the specified cast to IEnumerable doesn't work - but it works fine from the ListBox.  How do I tweak the code so that it will work for both controls?

Hi,

I'm saving by PersistenceMaganer on my GridView but when I try to reload it missed converter and formatstring in some column.

When reloading it doesn't apply Converter called FuoriCorsoConverter and StringFormat of "Last Update" column, durthermore other column with StringFormat is correctly applyed instead.

Why?

Codes:

XAML of columns

I am trying to default my FontSize to 8 and FontFamily to Arial, by doing:

I have an app that runs on a touchscreen and I am trying to capture the GotTouchCaptureEvent so that I can display the onscreen keyboard when the textbox is touched. It worked fine for a TextBox, but I am converting to RadMaskedTextInput controls to take advantage of the input masking and input validation. The event is fired from the TextBoxes (it works as desired if I change RadTouchTextBox to derive from TextBox), but not from the RadMaskedTextInput controls. The GotFocus and the LostKeyboardFocusEvent both work fine.

Here is the code:

ViewModel:

    public class RadTouchTextBox : RadMaskedTextInput
    {
        /// <summary>
        /// TextBox class with event handlers
        /// </summary>
        public RadTouchTextBox()
        {
                this.GotFocus += TextBox_GotFocus;
                this.GotTouchCapture += TextBox_GotTouchCapture;
                this.LostKeyboardFocus += TextBox_LostKeyboardFocusEvent;
        }

         private static void TextBox_GotFocus(object sender, RoutedEventArgs e)
        {
            (sender as TextBox)?.SelectAll();
        }

        private static void TextBox_GotTouchCapture(object sender, RoutedEventArgs e)
        {
            try
            {
                Process.Start(@"c:\Program Files\Common Files\microsoft shared\ink\tabtip.exe");
            }
            catch
            {
                // if the tabtip display fails for any reason, do nothing.
            }
        }

        private static void TextBox_LostKeyboardFocusEvent(object sender, RoutedEventArgs e)
        {
            Process[] processlist = Process.GetProcesses();

            foreach (Process process in processlist)
            {
                if (process.ProcessName == "TabTip")
                {
                    try
                    {
                        process.Kill();
                    }
                    catch
                    {
                        // if killing the process fails, ignore
                    }
                    break;
                }
            }
        }

        public string ServerPath
        {
            get { return GetProperty<string>(); }
            set { SetProperty(value); }
        }

xaml:

<DockPanel>

.

.

.

         <RadTouchTextBox Width="300" Margin="5" FontSize="24"
                 Value="{Binding ServerPath, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay, ValidatesOnExceptions=True}"
</DockPanel>

Any help is appreciated.

Hi, I have a gridview that can have configurable colums. Some of them use the default template, but others not. I have a problem with the ones that need to show icons.

Here is a sample of a datatemplate of a GridViewCell:

This works ok. The problem comes, for example, when I try to assing a tooltip:

I receive the next error when I scroll horizontally and the cell is going out of scope, the moment that I think the control will recycle the cell:

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.FrameworkElement', AncestorLevel='1''. BindingExpression:Path=Parent; DataItem=null; target element is 'StackPanel' (Name='IconFlagsCellTemplate'); target property is 'Parent' (type 'DependencyObject')

Also this produces that the horizontal scroll pauses a little bit when giving those errors, causing a notieceable visual delay.

But there is more. I need the image to be wrapped into a button, as I need to add a contextual menu to the button and some triggers, but this also produces the avobe error, no matter if there is tooltip or not. Fortunately, if instead of the button I put a ContentControl, but not tooltip, there is no problem as well.

I need, though, both tooltip and custom menu. And also there is need to keep into account that there will not be only an icon. There could be any number of icons, that will be shown or not depending on some ViewModel condition, as you can see with the bindings.

Hope anybody could help me by providing a working solution, as the client is complaining about the scrolling issue. Meanwhile I'll try to test other ways of doing things.

Thanks in advance.

David.

I am using MVVM to display a busy indicator. If I tell the indicator to show in an async on click event in code behind it shows up. However when I have my view model set the exact same property to true from a command it never shows up.

View Model Code the indicator never shows but if I remove the async call it shows up.

Hi,

this is the strange behavior:

I have a RadGridView its ItemSource setted with a VirtualQueryableCollectionView.

User set a filter and then export, I use this method:

Sometimes it exports with first row of sheet dirty, because in first row there isn't columns header, but a row that does not belong to the collection (filtered by user).

PS: Normally, the first times export correctly header row (columns label), after several times appears that showed in SequenceExport.PNG
