Is there a way to use the datafilter control without a datasource?

I need this kind of control to create filter expressions and save them for later use. I need to provide my own columns without the control getting them from a datasource and save the completed filter expression in a database table for later retrieval.

Thanks for your help.

I purchased the Ultimate Suite yesterday and my first day using it I cannot add several 2010 Q2 Rad Controls to my WPF form. Trying to add several of the Telerik controls generate the same error.

'/Telerik.Windows.Controls;Component/themes/windows7/BusyIndicator.xaml" value cannot be assigned to property 'Source' of object 'System.Windows.ResourceDictionary'. Type reference cannot find public type named 'RadBusyIndicator'. Error at object 'System.Windows.ResourceDictionary' in markup file 'Telerik.Windows.Controls;component/Themes/GenericWindows7.xaml.'

I get this error trying to add a RadChart, RadButton, RadDropDownButton, RadRadioButton, RadSplitButton, RadToggleButton, and the list goes on and on. For $2000 I was expecting things to work out of the box. Do I need to go to an older version of your product? Please help.

Hi ,
I am new to Wpf, EntityFramework and Telerik,
but i am trying to do the following :
I have a generic gridwindow ( telerik grid ) , that doesnt know what data it will display at compile time.
The grid is set to autogenerate the columns once it get a collection of data.

The data is a observable collection of EF Entities.
In the AutoGeneratingColumn event, I intercept each column.
columns of type Collection are skipped over,
columns of type String, Datetime or primitive types are shown.

I would like to replace the single columns to other Entities by n columns for their own primitive values.
So if i have a Entity Customer with a Property Address.
My grid would show by default :
Customer fields with binding path : Name, FirstName etc.
Address fields with binding path : Address.City, Address.Zip etc. all on the same row.

the code :
the Event :

 Telerik.Windows.Controls.GridViewBoundColumnBase c = gvc as Telerik.Windows.Controls.GridViewBoundColumnBase;
     if ((!c.DataType.FullName.StartsWith("Afda.Model.TrackableCollection"))
              &&  (!c.DataType.FullName.StartsWith("Afda.Model.Obj")))
                {
                    foreach (System.Reflection.PropertyInfo pi2 in c.DataType.GetProperties())
                    {
                        if (pi2.PropertyType.BaseType.IsValueType || pi2.PropertyType.FullName.Equals("System.String") || pi2.PropertyType.FullName.Equals("System.DateTime")
                            || pi2.PropertyType.BaseType.FullName.Equals("System.ValueType"))
                        {
                            Telerik.Windows.Controls.GridViewDataColumn newColumn = new Telerik.Windows.Controls.GridViewDataColumn();
                            newColumn.Width = c.ActualWidth;
                            newColumn.DisplayIndex = c.DisplayIndex;
                            String s = c.DataMemberBinding.Path.Path + "." + pi2.Name;
                            newColumn.DataMemberBinding = new Binding(s);
                            newColumn.DataType = pi2.PropertyType;
                            newColumn.DataFormatString = c.DataFormatString;
                            newColumn.TextAlignment = c.TextAlignment;
                            newColumn.Header = s;
                            newColumn.Name = s;
                            newColumn.UniqueName = s;
                            newColumn.Footer = c.Footer;
                            newColumn.IsVisible = true;
                            colsToAdd.Add(newColumn);
                        }
                    }
                    gvc.IsVisible = false;

In the load data method :
 

  try
            {
                DataGrid.ItemsSource = data;
             }
            catch { }
 
            foreach (Telerik.Windows.Controls.GridViewDataColumn c in colsToAdd) {
                if (!DataGrid.Columns.Contains(c)) {
                    DataGrid.Columns.Add(c);
                }
            }

PS : i also tried doing the add of the new column in the event itsself, but it seemed Icky , and gave a cryptic error.

Any comments ?? it seems to be working most of the time .  ( the embedded Entity isnt always loaded, even if the linq statment is always the same )

No real problems with it atm, so forum prob not the place to post this, but it wasnt working yet, when i started writing :)

I'd like to know a bit more about the DeferRefresh method on the RadGridView. What does it do exactly and how is it used? The documentation states: "Enters a defer cycle that you can use to merge changes to the view and delay automatic refresh" So does it effectively freeze updates from the data source? Do you stop the defer cycle by disposing the object that is returned from DeferRefresh?

Thanks!

I want to draw a 2D Pie, where the first "pie element" shall start at "12 o'clock" (not at 3 o'clock as default), and the folowing elements adds in clockwise order.

I also need the selected "pie element" to "pop out" when I select it by clicking on the pie, or selecting by code. How do I code this in C#?

I have 2010 Q2

Is there a way to get the timer value used by the spring zoom animation?
I have a dependency property linked to the zoom level and would like to animation between the new zoom level and old level to have the same duration.
Regards
Frederic

Using the latest WPF RadMap version (Q2 2010), I noticed that smooth zooming has been added (looks very good).
However, there is an unfortunate side effect on panning (it "lags").
Is there a property to control the spring effect on panning (e.g. turn it off)?
The UseSpringAnimations property turns both smooth zooming *and* panning on/off.
Regards
Frederic

Hi

This is trivial stuff but I can't find an answer in all your resources.

I have a database field containing an integer code e.g. Priority with 0 for High, 1 for Medium and 2 for Low.
The codes mean nothing to the user so I need to translate the code in this column into text. Also, when sorting the column I'd like it to use the underlying code and not the text so the ordered data appears as High-Medium-Low not text sorting which would give High-Low-Medium.

If you can provide some tips on searching your resources for this easy stuff that would be appreciated! A beginners guide maybe

Thanks

Hi,

On a page, I have a gridview which shows data which come from a binding to a collection of a class A.

What I want to do is to get the currently showed items on the grid view, transform the items into new items of a class B and bind the new item collection of the class B to a pie chart.

To do that, the only solution I could see was to use a converter.
What I've done compile fine, but when I run the application, the pie chart is empty whereas the grid view contains elements.

Here is the XAML code with the mapping on ItemsSource :


And here is the converter code :


In debug mode, when I look at dataItemCollection, it's empty !
So, converter can be use is that case ?
If not, how can I do it ?

Thanks.

Hello,

At the last release i have some problems with cell edit template. If i use my own cell edit template(first code block) the "tab" and "enter" buttons does not make the cell editable. It only focuses on the cell.
But if i don't make an edit template there is no such problem.(second code block)
Also at the cell edit template i need to make double click to go in edit mode. But at default only one click.

P.S : If i use the keyboard up/down arrows to change the value there is no problem. The problem is i can not enter numbers from the keyboad
