Hi Guys!

I am fairly new into Telerik business, so please apologize if this isnt the way to report a possible bug.

My recent project is a simulation software for thermal power plants. In a canvas the user can drag&drop
various powergrid objects and connect them to each other.

The user can enter math formulas using public properties of any object on the canvas. And here comes
radExpressionEditor into the game. In this project I am using ILGenerator to dynamicaly add Properties
at runtime. Unfortunately radExpressionEditor doesnt support multiple Item objects.

So much for a little background info. Now for the bug.....

I have a object with the following signature:

    public class DynamicFields : INotifyPropertyChanged
    {

        public event PropertyChangedEventHandler PropertyChanged;

        private int _Test;
        public int Test
        {
            get { return _Test; }
            set { _Test = value; PropertyChangedHandler("Test"); }
        }

        public DynamicFields() { }

        public void PropertyChangedHandler(string propertyName)
        {
            PropertyChangedEventHandler handler = PropertyChanged;
            if (handler != null)
            {
                handler(this, new PropertyChangedEventArgs(propertyName));
            }
        }

        // BUG: RadExpressionEditor sets a Handle on this.PropertyChanged, but doesnt have any Targetdelegate.
        // Lets remove it here as a workaround!
        public void RemoveLastPropertyChangedHandler()
        {
            Delegate RemoveDelegate = this.PropertyChanged.GetInvocationList().Last();
            if (RemoveDelegate != null)
            {
                this.PropertyChanged -= (RemoveDelegate as PropertyChangedEventHandler);
            }
        }


Some other place in my code I do something like this:

            //Window with ExpressionEditor that will be shown as a dialog
            Window_ExpressionEditor ee = new Window_ExpressionEditor();

            //FormelEditor is an instance of ExpressionEditor
            ee.FormelEditor.Item = Device.dynamicFields;

            //As soon the Item Property is set to my Dynamicobject, radExpressionEditor will subscribe to
            //the PropertyChanged event but without any target method to call.
            //So then ever I change the Value of a property the PropertyChangedHandler raises an exception.

            //Workaround is to delete last entry of the GetInvocationList()
            DynamicFields df = this.Device.dynamicFields;
            df.RemoveLastPropertyChangedHandler();


This behaviour also occurs if I use a "normal" class without expanding the properties at runtime.
Right now my workaround runs fine, but would be nice to get this bug verified.

Oh and please implement radExpressionEditor.Items for multiple objects use ;-)

Thank you and my best regards, Martin

How would you implement a hotkey for the Approve RadButton in the following code snippet?

I have a combo box with multiple combobox items.  (The example is implemented using MVVM)

Each combo box item contains
1. DatePicker for StartDate
2. DatePicker for EndDate
3. OK button.
4. TextBlock

When the combo box is expanded and
1. When I click on the DatePicker control, the combo box collapses.  I was hoping that the DatePicker control would show me the calendar and I could select the date, instead of collapsing the combobox.
(Note: The above behavior is only for RadComboBox and not the default ComboBox)

2. When I click on the "OK" button, I calculate the Text that has to be displayed and I am expecting the combobox to collapse. (I have Command set up for button to handle the click event). But the combobox does not collapse

What I would like is
1.  Not let the combobox collapse when I click on the DatePicker control to select a date
2. When I click on the "OK" button, the combobox should collapse (just like when an item is selected inside combobox)

Note:  I am using MVVM, so I don't have scope to use event handlers.

Thanks.

Hello,

I'm trying to add an event handler for the RowDetailsVisibilityChangingEvent, but I get a compiler error.

Shouldn't this be possible:

Tb.AddHandler(

 

GridViewDataControl.RowDetailsVisibilityChangingEvent, new RoutedEventHandler(GridView_VisibilityChangingEvent));
The doc says it's part of the GridViewDataControl class.

Best regards
Oliver

 

Hi,

How can I add a marked zone in a programmatically way? I tried to look in the chart area object within the radchart but I couldn't find it.
I'm working with WPF.

Cheers

 

Hi,

I have a main application and when the user click on a button, I create a dialog to display some informations. When a display this dialog, I restore his persistence and whe the user close this dialog, I save his persistence. After 2 or 3 attempts of displaying this dialog, my main application throw me an exception.

In my RadChart (2011 - Q3), I have two Y axis. I would like to have a custom grid line drawn against my second Y Axis, which is named 'CdSimStdDev'. Is this possible to do in XAML. I don't see a way to specify the name of a Y axis to associate with the custom line.
Thank you.

Hi

I would like to control the visibility of the backstage component via my viewmodel through databinding, see below.


Although I get no errors, the ribbon is not responding to changes in my property value. (I am notifying the property change).

Any ideas?

Hi!

I am looking for a Telerik text box control that does validation of the data when the "Enter" key is hit.  The validation should be similar to the Telerik data grid.  On the data grid the "Enter" key forces a validation without losing focus.  Is there a telerik textbox control available that I can take advantage of?  if you can show me an example that shows how to implement this.

For example:  If the textbox is bound to a number and user enters a letter and presses "Enter" then the border of the textbox get highlighted to red without losing focus.

Thanks,

Sonia

Hello,

I try to display a list of UserControls in a RadTabControl and to use a UserControl property (name) to display tab header and dropdown items.

According to this post (http://www.telerik.com/community/forums/wpf/tabcontrol/radtabitem-headertemplate-not-responding-to-binding-to-usercontrol-object-properties.aspx), I succeded in displaying Tab Header with UserControl "Name" property.
To do this, I use a RelativeSource :

Text

 

 

="{Binding DataContext.Name, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=telerik:RadTabItem}}"

 

I have used your TabControl-Q1.zip sample project (from post above) where I have modified MainWindow.xaml.cs file to create a list of UserControls :

this

 

 

.radtabVariableControlsContainer.ItemsSource =

 

 

 

Enumerable.Range(0, 10).Select(x => new UserControl() { Name = "name" + x });

 

My RadTabControl and related template definition is this one :

It so work find for ItemTemplate to display Tabs Header, but I don't succeed in displaying UserControls names in DropDown.
The "name" property never appear in dropdown...

Many thanks for your help !
