How to start

This is my first experience with WPF and Telerik.

When I create an empty WPF project in VS2008, I'm given a Window1.xaml and the outer component is <Window x:Class="..." >

If I'm going to use the Rad controls throughout, should I replace that with telerik:RadWindow? If so, how? When I drag a RadWindow into my current canvas, it is nested. When I run the app, I don't see the RadWindow.

Essentially I'm looking to have a base window for my app that has a RadPanelBar on the left side as the primary menu, and a main content area that will hold multiple windows created dynamically based on menu selections.

I'm not sure what the foundation of a Telerik WPF app should start with.

Thanks,
ms

Way to hide a column?

I have a dataset that is a master/detail, displaying as hierchical data.

The 2 tables are joined on a column called "InvoiceID"

I do not want to show the "InvoiceID" column in the detail data

Without defining every column that should be displayed in xaml, is there a way to specify a column that I want to hide? Thanks

Multi room calendar issues

Hi folks -

I am trying to create a multi-ROOM calendar (think mult-day, but instead of say 7 days being displayed, 7 room schedules are displayed). That is, I would like to have several day calendars displayed side by side, where each is the schedule for a single day's worth of events in a particular room.

I have placed several one-day views adjacent to each other, but I still have some remaining issues in order to make the full deal. You can see a picture of where I am at by clicking here: http://bit.ly/13IAYs

1. I would like to remove the forward and back by day arrows and date header information ("wednesday, August 19th, 2009") - just get rid of it completely. How do I do that?

2. I would like to replace the dates in the day header (highlighted in the picture) with the room names. How do I customize those?

3. I would like to get rid of the strange anomaly where the day header is bumped over to the right (Circled in red on the picture). Any ideas what is causing this?

Many thanks
Josh

Error while updating RadNumericUpDown

Hello, I've discovered an issue, and I'd like to see if this is some sort of desired behavior or a bug. Here's the deal, I've got a bunch of RadNumericUpDown controls, each lies within a UserControl. and that UserControl is bould to an object. the RadNumericUpDown XAML looks like this.

                            <telerik:RadNumericUpDown Grid.Column="1"          
                                              x:Name="inpPMax" Style="{StaticResource InputNumbers}"         
                                              ValueFormat="Numeric" NumberFormatInfo="{Binding Path=DisplayFormat}"         
                                              IsEnabled="{Binding Path=UserEntered}"         
                                              Minimum="{Binding Path=Minimum}" Maximum="{Binding Path=Maximum}"         
                                              SmallChange=".1" LargeChange="1" GotFocus="inpPMax_GotFocus" ValueChanged="inpPMax_ValueChanged">         
                        <telerik:RadNumericUpDown.Value>         
                            <Binding Path="DisplayValue"  UpdateSourceTrigger="PropertyChanged" ValidatesOnDataErrors="True"/>         
                        </telerik:RadNumericUpDown.Value>         
                    </telerik:RadNumericUpDown>         
                     

and the syle I'm using looks like this

                                <Style x:Key="InputNumbers" TargetType="{x:Type telerik:RadNumericUpDown}">         
                            <Setter Property="Height" Value="25"/>         
                            <Setter Property="FontSize" Value="12"/>         
                            <Setter Property="Margin" Value="2"/>         
                            <Setter Property="HorizontalContentAlignment" Value="Right"/>         
                            <Style.Triggers>         
                                <Trigger Property="Validation.HasError" Value="true">         
                                    <Setter Property="ToolTip"          
                                        Value="{Binding RelativeSource={RelativeSource Self},          
                                            Path=(Validation.Errors)[0].ErrorContent}"/>         
                                </Trigger>         
                                <Trigger Property="Validation.HasError" Value="false">         
                                    <Setter Property="ToolTip" Value=""/>         
                                </Trigger>         
                            </Style.Triggers>         
                        </Style>         
                     

The behavior I'm noticing is that when I enter "1000" in the text field, the control resets it back to 0, actually it looks like it sets it back to "000.000". I thought that it might be doing this because I set the min and max values incorrectly, but when I debug into the "inpPMax_ValueChanged" method, I see that the control's max is set to double.maxvalue, and min is set to double.minvalue which means to me that it should't be failing this test. I've also tried hard coding these values to 0.0, and 10000 respectively, with the same results.

I've noticed that if I enter 1999 (which is larget then (1000), the control resets the value to "999", to me it seems that the control is only taking the first 3 degits. One other thing to note is that the binding for NumberFormatInfo looks like this.

                            public NumberFormatInfo DisplayFormat         
                    {         
                        get         
                        {         
                            var ret = (NumberFormatInfo)CultureInfo.CurrentCulture.NumberFormat.Clone();         
                            ret.NumberDecimalDigits = DecimalPlaces;         
                            return ret;         
                        }         
                    }         
                    protected virtual int DecimalPlaces { get { return 0; } }         
                     

This is because some "measurements" require 3 decimal places, while others require 0 and the control just binds to the "measurement"s DisplayFormat property.

it's going to be difficult to send any more code, but I'd greatly appreciate any help here, and I'll send whatever you ask for, if I can't get this to work I'll have to go back to a textbox, and I really don't want to do that.

Is possible to bind IQueryable data source to your grid in such way that it loads record from data source in fragment? Now when i bind collection, that implements IQueryable, grid retrievies all record (in my case it takes up to 2 minutes ).

WPF scrollbar and drag drop tooltip styling

Hi

I would like to change the WPF Treeview scrollbar colours, editing the template has yielded some minor results, I managed to change the color of the bottom right area to green (where the horizontal and vertical scrollbars would interleave if extended) but I cannot change the main scrollbar colors, I think this would be the Thumb and RepeatButtons and other such scrollbar elements. It is as if values are coerced from some higher priority property, as I can find the elements, but changes are not reflected at design or runtime. Screenshot: http://i30.tinypic.com/x21gld.png

My second request is how to make the drag and drop tooltip appear adjacent (to the right) of the mouse pointer when the operation starts. This was the behaviour I had with an earlier version of Telerik WPF but upgrading to version 2009.2.701.35 seems to have broken this. The issue is that the drag/drop tooltip is appearing about 100 pixels to the right of the mouse pointer, which looks weird.
Any ideas would be helpful. Screenshot: http://i29.tinypic.com/6t3cqt.png

Event for Spinner Click

Is there an event that indicates when the value has changed via the spinner not just that the value has changed? I have a situation where a change in the value from the spinner results in rebinding the value which triggers the ValueChanged event which rebinds... A spinner click or something equilivent would solve the issue or even better would be the ability to suppress the value change event when the cause of the change is data binding vs. the UI.
