I have problem with the RadGridView, and my own ObservableDataRow. The grid throws an exception if i click on the filter symbol in a grid. This problem occures if i bind to the following object:

The error does NOT occure if i declare the collection like this:

But i also fill the list with instances of ObservableDataRow.

The exception: No generic method 'Select' for the type 'System.Linq-Quieryable' is with the provided type argument and arguments compatible. No type argument should be provided, if the method is not generic. (Translated from a german error message - may not the same as thrown in english.)

Using RadObservableCollection<DataRow> solved the problem, but there must be a bug.

Or did i some thing else wrong?

As an additional information, i have also created my own ObservableDataTable for creating instances of ObservableDataRow.

Thank you.

How can I control the size of the geometry in the RadGeometryButton. I'm using Syncfusion Metro Studio 3 for my assets and the geometries do not fit inside the circle. See attached screenshots for clarification.

I have  an extremely simple layout: A RadDocking control that contains a single RadPane. The pane will always be visible, never floated, etc. Within that are some controls, including a ScheduleView.  Like many others have asked, I want to detect when the control closed. I can see the PreviewClose event fire if I allow the pane itself to close. I also see the Close event fire if the pane is closed.

However, if I close the RadDocking control, the Close event never gets called. What am I missing? I have spent about four hours now tracking down something that should be extremely simple. If I have edited the content of my control, and click the 'x' on the RadDocking control, throw up a message warning the user of unsaved changes. If the user says 'OK', then save the form and close. If they say 'Cancel', stop the process.

For the life of me I don't see where to hook into events (OnStateChanged is the only event I see firing when the RadDocking closes, and I can delegate the event, but the RadDocking still closes).

<telerik:RadDocking HasDocumentHost="True"  HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
        <telerik:RadDocking.DocumentHost>
            <telerik:RadSplitContainer IsTabStop="True" Orientation="Vertical" x:Name="SplitContainer">
                <telerik:RadPaneGroup HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
                    <telerik:RadPane CanFloat="False" CanUserPin="False" CanUserClose="True" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" IsTabStop="True" IsDragDisabled="True"> 

 ....controls ...

                    </telerik:RadPane>
                </telerik:RadPaneGroup>
            </telerik:RadSplitContainer>
        </telerik:RadDocking.DocumentHost> 

Thoughts?

Hi there,

 I am developing a WPF application using MVVM pattern and I need to display data in a format attached below.

The first column is for time with some interval. The time and the interval can vary so accordingly the total number of rows could be more or less.

After this I need exactly 5 more columns.

 Can you please suggest an appropriate control to fulfill my requirements.

Thanks

I would like to select a specific cell by giving the column and the row index. For exemple (Image): 

I would like to select the cell where the column index is 2 and the row index is 2 (It will select the cell where "Portugal" is written).

It should be something like myGrid.SelectCell(Columns[2], Rows[2]);

Is there any way of doing this?

Thank you,
Evelyn

When I call the RadSpellChecker control to spellcheck a textbox it is slow the first time:

RadSpellChecker.Check(txtBox, SpellCheckingMode.AllAtOnce);

Sometimes the RadSpellChecker window ​appears behind the parent window. Also, if I click on the application icon on the task bar, the RadSpellChecker window goes behind the parent window.  I can deal with this, but my users can't.  Is there a setting that I'm missing to set the RadSpellChecker control to be the topmost window?

Hello,

I'm trying to add a RadGridView in my ModernUINavigationApp and I'm not capable of making it work. I have uploaded a simple proyecto to DropBox:

https://www.dropbox.com/s/7wqyisvdywcx817/ModernUINavigationApp3.zip?dl=0

 I just made a copy from telerik demos but I can't even see the RadGridView on Design.

 Could you please check it out and tell me what I'm doing wrong.

Many thanks.​
