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 :)

Dear team,

I have a customized column that constains my own usercontrol inside. The column works perfectly but when we sort by another column, this column don't move. 

This is my column definition:

<telerik:GridViewDataColumn                                    
                                    Width="*"
                                    Header="{Binding Source={StaticResource appResx}, Path=ep_ClearOpeningRange}"
                                    HeaderTextAlignment="Center"
                                    IsReadOnly="False">
                                    <telerik:GridViewDataColumn.CellTemplate>
                                        <DataTemplate>
                                            <StackPanel>
                                                <TextBox Text="{Binding ModelOpeningSill.OpeningType.ProductAttributeValueCode}" />
                                                <my:MultiRangeSlider                                                    
                                                    Id="{Binding ApplicationRangeId}"
                                                    Maximum="3000"
                                                    Minimum="600"
                                                    PropertyChangedCommand="{Binding DataContext.ApplicationRangeChangedCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:ModelDetailView}}}"
                                                    Thumb1="{Binding CertifiedMinimumClearOpening, Mode=TwoWay}"
                                                    Thumb2="{Binding CertifiedMaximumClearOpening, Mode=TwoWay}"
                                                    Thumb3="{Binding RecommendedMinimumClearOpening, Mode=TwoWay}"
                                                    Thumb4="{Binding RecommendedMaximumClearOpening, Mode=TwoWay}"
                                                    TickFrequency="50" />
                                            </StackPanel>
                                        </DataTemplate>
                                    </telerik:GridViewDataColumn.CellTemplate>
                                </telerik:GridViewDataColumn>

 

My usercontrol is a multirange slider called: <my:MultiRangeSlider>. The textbox inside the StackPanel is sorted correctly but my usercontrol is totally static.

Attached captions maybe can help to understand my problem. In these captions the textbox inside the stackpanel was hidden (only was created for test).

Thanks in advance!

Hi,

 

My child nodes seem to have a "mystery" column in front of the actual item, and you can only see it if you click on it. If you click on it, the items itself de-selects, and the "mystery column" in front of it becomes active for that row. How do I blend/merge/remove the blank column in front of all my child node rows ?

 

Thanks,

Barry

 

Hi,

I am using many controls in my enterprise WPF application, which includes- RadGanttView, Combobox, etc.

The application runs perfectly fine when the windows text size is set at 125% or 150%.

But, when set at 100%, the text on the controls starts disappearing on mouse over. The issue is exacerbated by the fact that once the text starts disappearing, the buttons, and other actions stop working. The buttons, and RadGanttView items get clicked, but nothing happens. 

This happens on both Windows 7 and Windows 8.1 systems. PFA a snip of the issue occurring on RadGanttView.

Is this related to something in the controls? Or am i missing something here?

Please help.
Thank you!
