Hi
 I would like to create a usercontrol that will allow me have a set a predefined columns within a GridView when bound to a collection of our DataContract classes.   What I would like to see is something on the order of the Data Template Selector... but instead, have that at the GridViewDataColumn level.   Here is an example

[DataContract]
public MyDataClass
{
Public SomeEnum EnumProperty {get;set;}
        Public SomeClass SomeClassProperty {get;set;}
Public int SomeIntProperty {get;set;}
}


Now  lets say I have a List<MyDataClass> and I want to bind this to a RadGridView control and have it auto generate the columns based on some defined logic. I know that I could probably do this in the Auto generate event handler in my code behind though a series of if logic or case staements.  But I would prefer it if there was a way that I can define some sort of a GridViewDataColumnSelector to have it automatically define both of the read only and editor templates. Something on the order of what we have for Data Template or Style Template selector except for the entire GridViewDataColumn.

For the example above.. I would like to auto-generate a Combobox for the Enum to provide a list of Enum possible values.  And for the SomeClass property.. I want to create a ComboBox with a list of values bound to collection of possible values. 

Hello

When setting the IsEnabled property of a RedNumericUpDown control to false, there is almost no visual change. Only the control does not change its border any more when hovering over it. But there is no gray background or anything like that.
When we experienced that, we tried to do it using a trigger and setting the Background property but the Background property does not seem to work.

Is there any simple solution to that apart from putting a whole new ControlTemplate?

Best regards

Christian

Please provide me the code to remove the gradient effect on bar charts, I understand I have to create a custom style to get rid of the default mask but every example on here is either for pie charts or I haven't been able to get them to work.

Many thanks.

I have a RadGridView that displays data from my database.  I have set up a DataTemplate for the RowDetails:

In order to speed loading of the data, I have implemented the following:

1. I have implemented a class called CustomGridViewToggleRowDetailsColumn which descends from GridViewBoundColumnBase.  This class has properties that allow me to hide the GridViewToggleButton for a row if that row does not have any row details.  It also has a Click event that is raised whenever the user clicks on the GridViewToggleButton.
2. In my class that populates the rows of the RadGridView, I have implemented INotifyPropertyChanged.
3. In the window that has the RadGridView, I retrieve my data from the database but leave the Alarms property (which is bound to the DataGrid's ItemsSource property in the DataTemplate) set to null initially.  A bool property called HasAlarms is set to true if the row has Alarms associated with it.
4. In the window that has the RadGridView, I have a Click event handler for the custom Click event I mentioned in #1.  This checks to see if the Alarms property for the row that was clicked is null.  If it is, it goes to the database and retrieves the Alarms.  Note that this event can't happen unless HasAlarms is set to true for that row.

This is all working, but the DataGrid remains empty after the RowDetails are displayed.  What am I missing to make this work?

Hi,

actually with my VS2008 I use V2011.3.1220.35 and I'm trying to upgrade to V2012.1.326.35 and I have some questions. Actually
my "C:\Program Files (x86)\Telerik\RadControls for WPF Q3 2011 SP1" folder contain the following folders:

Binaries
Demos
LicenseAgreements
Themes
VSExtensions

and the new folder ("C:\Users\agosselin\AppData\Roaming\Telerik\Updates\RadControls_for_WPF_2012_1_0326_Dev_hotfix") created by Telerik download process contain the following folders:

Binaries
Binaries.NoXaml
LicenseAgreements
Themes.Implicit

the folders structure are not the same!!! I would like to know what should I do and consider to upgrade my current version of Telerik???

PS: In our development environment, we have a specific folder containing each Telerik versions regarding the one we use with the project we work on.

Thank's

I have a reference to an object that is in the RadGridView, but it is not necessarily the currently selected object in the RadGridView, and I need to find the object that immediately precedes or follows it.  I have an ObservableCollection of objects, but the order of the objects in the ObservableCollection does not always match the order of the rows in the RadGridView, since the user can sort the RadGridView.

Is there a way I can retrieve a reference to a collection of the RadGridView's items that is in the same order as the data currently is in the RadGridView?

What is the best method to determine if a given Diagram has changed (i.e. attributes of a shape changed, new shape, etc.) when not using a diagram bound with GraphSource?

I sent a support ticket to the telerik admins asking if there were any API methods to determine if the caret is at the start and end of a line.
They responded with a solution so I thought I should share it with everyone else.

Is Caret at Line Start

Is Caret at Line End

I hope this helps you as it did myself.

Thanks,

Rob

Hi,

I'm trying to use the RadMaskedNumericInput as follows;

<telerik:RadMaskedNumericInput
                Grid.Row="6"
                Grid.Column="1"
                Value="{Binding Mileage}"
                EmptyContent="kilometer"
                FormatString="D"
                Mask="d"
                IsClearButtonVisible="False"
                VerticalAlignment="Center"
                VerticalContentAlignment="Center"
                />

...where the bound 'Mileage'-property is an Int. But when I try to input a number at runtime, I get the following exception;

"Index was outside the bounds of the array."

And the stacktrace;
