Greetings

Currently I'm not that experienced with styles in WPF and after some research I decided to give it a shot to ask. 

I'm working with with the RadGridView and I'd like to change the Foreground of the header of a sorted column. 

Within the styles of Telerik I found there are some visual states to determine the colour of the border or for the ascending/ descending arrow. Yet there is no description to change the colour of the Foreground. 

Yet doing some research, I found some code to add to change the Foreground as well within the VisualState. 

Yet, this isn't working. This entirely breaks the VisualState of 'Ascending'/ 'Descending' and the following exception within Output can be found:

Sorry for asking perhaps a dumb question. I'm still in the learning process of Telerik styles and WPF styles in general. 

Kind regards

I have an editable RadGridView with set column widths.  When the user clicks a cell to edit its contents, the editing TextBox appears to be much more narrow than the width of its column.  How can I change this so that the TextBox stretches to the column width?

I tried using a template for the cell but this prevented the cell/row validation from working:

Then I tried setting the CellStyle property, but this had no effect:

Hi,

I'm using Isolated Storage, and save a value to both the TreeListView and it's GridViewDataColumn...but when my page comes up the saved sorting value is not being used, so I have to use a third value and read it and manually sort:

 

XAML:

            <telerik:Label x:Name="ProjectTreeViewOrdering" Content="ASC" Visibility="Collapsed" telerik:PersistenceManager.StorageId="THOR_ProjectsTreeSorting" />

 

CODE:

        string[] projectsSortingIsolatedStorage = { "THOR_ProjectsTreeSorting" };

 

        private void OnWindowLoaded(object sender, EventArgs e)
        {

                isoProvider.LoadFromStorage(projectsSortingIsolatedStorage);

                IEnumerable<TreeProjectViewModel> projects = ProjectsTreeView.ItemsSource as IEnumerable<TreeProjectViewModel>;
                if (ProjectTreeViewOrdering.Content.Equals("Ascending"))
                {
                    ProjectsTreeView.ItemsSource = projects.OrderBy(p => p.Name);
                }
                else if (ProjectTreeViewOrdering.Content.Equals("Descending"))
                {
                    ProjectsTreeView.ItemsSource = projects.OrderByDescending(p => p.Name);
                }

...which gets my TreeListView sorted, but then all the Groups collapse, which I don't want.

Using "ExpandAllGroups" had no effect.

If anyone has a better and more proper way to sort, save, and load a RadTreeListView that has a GridViewDataColumn defined within it, I sure would love to know about it. To get the list sorting to persist, I currently have a value save in the TreeListView, the GridViewDataColumn, and a "desperate" label as seen above.3 values seems like overkill to get the job done. I found without the value int he GridViewDataColumn being saved, I'd get no arrows in the TreeListView control, which was bad. Without the label value being stored, I got no sorting capability....so it's all bad at the moment.

Hi, I have a RadGridView which is setup to have:

RowVirtualization=True
ColumnVirtualization=True
SelectionMode=Extended
ClipboardCopymode=Cells,Header
AutoGenerateColumns=False

There are 6 columns in this grid all bound to strings similar to
<telerik:GridViewDataColumn Header="FirstName"  DataMemberBinding="{Binding Name}">

I have populated the grid with ~60,000 records

Pressing ctrl+A to select all takes about 3 seconds (which I am ok with I guess)
My problem is pressing Ctrl+C to copy all the rows just freezes the UI and it never finishes (I force closed the app after about 5 minutes if I walk away for about 20 it finishes eventually)

Why does copying all these rows take so long? Is there a way I can speed it up?
I made sure I populated the grid completely first so all this time taken is purely the copy method?

 

Hello,

 

I am using a RadGridView with a RadDataPager to display a collection of items.

I use a GridViewSelectColumn to enable to select some of these items and to perform actions only on those who are selected.

My issue is that when I check the GridViewSelectColumn of some items, if I change the page and that I go back to the previous one, the items are not selected anymore.

I searched the forum and tried a few things but nothing worked.

 

Thanks in advance.

Regards,
Adrien.

Hello,

when I bind the TaskSource of the RadGanttView (WPF) to a CompositeCollection I get the Exception "Object of Type System.Windows.Data.CollectionContainer cannot be converted to Type IGanttTask". With the RadTreeView it works. All Items in the Collections implements IGanttTask.

 

Hello,

I'm using RadTabControl with TabStripPlacement="Left" 

In the past the RadTabItems were shown on the left side from top to bottom. Now they are placed from bottom to top. When changing the code to TabStripPlacement="Right" they are listed from top to bottom - like I want it happen on the left side.

I think I haven't changed anything. May it be a change in one of the two last versions?

Hi all,

I am working on a WPF application using Telerik (http://www.telerik.com/) and coded in C# .NET.
My following question goes over an ASP .NET page using the model “Code behind” to implement the logic of the page.

I would like to get the position of the GanttPresenterSplitter in a <telerik:RadGanttView>.
This information would allow me to set the position of another element in another part of the same screen.
I would also know if it is possible to add an event handler on that GanttPresenterSplitter in order to get its position each time that line moves.

The ASP .NET page is split into 3 parts (please find in attachment "draft_screen.png") :
- Red square : <telerik :RadGanttView>
- Green square : <telerik :RadGridView>
- Blue square : <telerik :RadScheduleView>

As you can see, there is a dividing line between <telerik :RadGridView> and <telerik :RadScheduleView>.
I would like that line moves at the same time and same position as the GanttPresenterSplitter in the RadGanttView.

Using a more explicit picture based on an example (please find in attachment "explicit_screen.png") :
- Orange line : GanttPresenterSpliter
- Purple line : GridSplitter

My point is to coordinate the orange and the purple lines in order they have the same position all the time.

Any help will be much appreciated J

Hello!

I have started to use the RadLayoutControl and it works great. However I am wondering if it is possible to save the layout after the user has made some changes to it?

Hi all,

I am working on a WPF application using Telerik UI for Silverlight (http://demos.telerik.com/silverlight/#RichTextBox/TelerikEditor) and coded in C# .NET.
I took the code of the previous link  and set it up to fit my needs.
I am now facing to an issue : How to directly load by coding a .rtf document into a RadRichTextBox ?

I tried two ways :
RtfFormatProvider provider = new RtfFormatProvider();
RadDocument = null;
using (FileStream stream = new FileStream(FileName, FileMode.Open))
{
    document = provider.Import(stream);
}
DocumentFragment docFrag = new DocumentFragment(document);
radRichTextBox.InsertFragment(docFrag);
-> But that way causes an error because the “Import” method returns a RadFlowDocument whereas I am expecting a RadDocument.

RtfFormatProvider provider = new RtfFormatProvider();
            Telerik.Windows.Documents.Model.Section section = new Telerik.Windows.Documents.Model.Section();
            Telerik.Windows.Documents.Model.Paragraph paragraph = new Telerik.Windows.Documents.Model.Paragraph();
            string line;

            using (StreamReader stream = new StreamReader(FileName))
            {
                while ((line = stream.ReadLine()) != null)
                {
                    Telerik.Windows.Documents.Model.Span span = new Telerik.Windows.Documents.Model.Span(line);
                    try
                    {
                        paragraph.Inlines.Add(span);
                    }
                    catch(Exception e)
                    {
                        string x = e.StackTrace;
                    }
                }
            }
            section.Blocks.Add(paragraph);
            radRichTextBox.Document.Sections.Add(section);
-> There, even if there is no error, the problem is that nothing is shown in the editor.

The most strange is that, when I run the program without trying to load any document at the opening, the window opens perfectly and all the buttons react with the right behavior (see attachment “RadRichTextBoxEditor.png”) but I am not allowed to load a .rtf document whereas it is allowed on the link provided at the top of this topic. (see attachment “notSupportedRTF.png”)

Any help or tip will be much appreciated :)
