When we print any large (10-500 pages) document  using WPF PdfViewer the UI becomes unresponsive. For the document with 100 pages it might take minutes. Are there any solutions for PdfViewer that improve User Experience printing large documents? To be more specific, is there a way to:

Show the progress bar with number of pages completed and left or % done with "Cancel" printing job button

OR

any other solution that would help to implement asynchronous printing?

Hi,

While for all major UI apps my organization is using RagGridView, for a side project that crept up a few months back, we need just the RadGridView. The app in question already has metro style implemented using a third party UI framework. We need just the radgridview in this app and since the app has a metro looking UI, we want the radgridview to sport the metro look.

Can someone please point out how to use achieve this without affecting the entire application's look and feel (I mean thememanager, affects the  entire application)?

regards,

Sid

I have a cellstyleselector

public class MyStyleSelector : StyleSelector
    {
        public override Style SelectStyle(object item, DependencyObject container)
        {
            return MyStyle;
        }
        public Style MyStyle { get; set; }
    }

I have a grid called DashboardGrid where I add columns in the code behind as they are dependent on columns which the user wants to see. I do this in the following code.

foreach (var deliverable in viewModel.Profile.Deliverables)
{

                GridViewDataColumn myColumn = new GridViewDataColumn();
                myColumn.DataMemberBinding = new Binding(deliverable.Path + ".My")
                {
                    Converter = dateToWeekNumberConverter //Using a converter
                };
                myColumn.Header = "Col1";
                myColumn.UniqueName = deliverable.Path + ".My";
                Style style = new Style(typeof(GridViewCell));
                Setter setter = new Setter(GridViewCell.BackgroundProperty, new Binding(deliverable.Path + ".MyBackgroundBrush"));
                style.Setters.Add(setter);
                DeliverableStyleSelector deliverableStyle = new DeliverableStyleSelector();
                deliverableStyle.DeliverableStyle = style;
                myColumn.CellStyleSelector = deliverableStyle;
                this.DashBoardGrid.Columns.Add(myColumn);

                GridViewDataColumn myColumn2 = new GridViewDataColumn();
                myColumn2.DataMemberBinding = new Binding(deliverable.Path + ".My2")
                {
                    Converter = dateToWeekNumberConverter //Using a converter
                };
                myColumn2.Header = "Col1";
                myColumn2.UniqueName = deliverable.Path + ".My2";
                Style style = new Style(typeof(GridViewCell));
                Setter setter = new Setter(GridViewCell.BackgroundProperty, new Binding(deliverable.Path + ".MyBackgroundBrush2"));
                style.Setters.Add(setter);
                DeliverableStyleSelector deliverableStyle = new DeliverableStyleSelector();
                deliverableStyle.DeliverableStyle = style;
                myColumn2.CellStyleSelector = deliverableStyle;
                this.DashBoardGrid.Columns.Add(myColumn2);

}

When 'My' > 'My2' then the MyBackgroundBrush is changed to Brushes.GreenYellow. The code works fine until I scroll through the grid. Then the cell styles are gone. PFA the screenshots. Please help me.

Note:  I can't add the styles in the xaml as I dont know how many deliverables are going to come. It can range from 1 deliverable to 100 and their setter is dependent on the MyBackgroundBrush and binding, deliverable.Path whose values again will be different as the deliverables.

Hi! Our colleague Eugene writes periodically in your forum. We use RadTreeListView in our project. As datasource for RadTreeListView we use an ObservableCollection containing hierarchical data. This hierarchical data are displayed in RadTreeListView perfectly well. Please see "Picture.PNG" file attached. But we can't edit information in any cell in second column. When the user does doubleclick on a cell and this cell is switched in edit mode then the data in the cell disappears and the user can't print the new data there. Please see the cell image in edit mode in "Picture2.PNG" file attached. Below is XAML concerning RadTreeListView in our application:

Where 'ProfileTreeRoot.ChildProfileElements' is ObservableCollection instance. 'ProfileTreeRoot' itself is the instance of Group class where ObservableCollection is. Below is Group class definition. You can see 'ChildProfileElements' ObservableCollection definition there.

Group class reprecents group containing some registers and some other groups. As you can see the ObservableCollection in Group is defined as the follow:

Below the definition of ProfileElementType class and Register class. First 'Register' class is shown:

And here is ProfileElementType class definition:

Can we (in our case) edit cells in RadTreeListViev? After all, if their content is displayed perfectly, then why can not edit it? We really need to get a cell in RadTreeListViev edited. Please help us.

I write C# WPF MVVM Prism 6 multimodule application in MS VS 2015. In my application I use your Telerik for WPF library that was updated in May 2016. In one of Prism modules I try to change one of the views from PrismUserControl(WPF) to telerik:RadWindow (as you have written in your instruction on: http://docs.telerik.com/devtools/wpf/controls/radwindow/how-to/use-radwindow-as-user-control). But when I create RadWindow according to abovementioned instruction then the following error has place: "XamlObjectWriterException: Setting of "System.Windows.ResourceDictionary.Source" property throws an exception".

Moreover. If I add in XAML, for example, telerik:RadButton or telerik:RadTreView then (in design-time)  "Cannot locate resource 'themes\genericvista.xaml' error occurs.

Below I dusplay contents of App.XAML file from Shell project of my application solution:

What the reason of "Cannot locate resource 'themes\genericvista.xaml' error ? How to eliminate it? Please help.

Hello,

I'm having the following issue with the Serialization process in the diagram:

When I save the first time, it works great. (I can reload the layout several times and it works perfectly: my items go back to their saved positions)

However, if I saveLayout, then LoadLayout, the next time I'm going to call SaveLayout will fail because node is null in the GetNodeUniqueId override.

Any idea what could cause this? Thanks!

Hi,

I am using the richtextbox with theming having a dark background. I now would like to permanently set the textforecolor to a light color (like white, depending on the selected dark theme) so that
1.) regular text is displayed with a light forecolor
2.) pasted plain text  is inserted and displayed with a light forecolor
3.) richtext forecolor is changed to a light forecolor
4.) when using the color picker the 'automatic' color is the light forecolor that has been set recently.

what I have so for:

Until now I couldn't find a way to achieve this. How would I have to proceed to get this szenario implemented? Any example/solution?

Thanks in advance.

Hello, 

Can anyone please explain to me how to resize the row height whenever the RadGridView height is changed at runtime?

Thanks in advance.
