Hello!

I have a grid, one column is for edit different data:

 <telerik:GridViewDataColumn
                                                Width="*"
                                                CellTemplateSelector="{StaticResource TypeCellTemplateSelector}"
                                                DataMemberBinding="{Binding Value}"
                                                Header="Value" />

TypeCellTemplateSelector chooses DataTemplate:

 <templateSelect:SettingCellTemplateSelector.ComboBoxTemplate>
                    <DataTemplate>
                        <telerik:RadComboBox
                            DisplayMemberPath="Description"
                            ItemsSource="{Binding Value.EnumValue, Converter={StaticResource ValueToEnumConverter}}"
                            SelectedItem="{Binding Value.Value, Mode=TwoWay}"
                            SelectedValuePath="Value" />
                    </DataTemplate>
                </templateSelect:SettingCellTemplateSelector.ComboBoxTemplate>

ValueToEnumConverter reterns collection, 

BUT when it shows RadComboBox is empty

please can You help me?

In the program code, I create a Radpane and add it to a RadPaneGroup. The user can close the RadPane and open it in the RadRibbon Menu.

How can I realize that a RadPane is only opened once?

Assuming the following view model. How do I bind the VisibleItems collection to the RadGridView? One-Way binding would be sufficient, as I would deactivate any filtering from the UI side. Performance is important.

​Cheers,

Jan

Hello,

I've written a custom selection behavior in order to support un-selecting points when clicking on an empty (non-Data Point) area of the chart. This behavior works pretty nicely. However, as soon as the chart is zoomed or panned in any direction, the click ends up selecting a point to the upper-left of where I actually clicked. The main algorithm of the click selection is below. Is there a specific pan/zoom offset that I'm supposed to take into account?

var rect = new Rect((myMouseButtonEventArgs.GetPosition(this.Chart as IInputElement), new Size(myHitTestMargin));
if(this.Chart is RadCartesianChart)
{
    var chart = this.Chart as RadCartesianChart;
    var points = chart.Series.SelectMany(s => s.HitTestDataPoints(rect)); //-- this returns the wrong set of points when zoomed or panned
    //-- Create a new arguments object with these points and invoke a custom event with those args
}

I have a couple questions regarding the use of RadPivotFieldList with a LocalDataSourceProvider:

1) When I try to add a CalculatedField to the LocalDataSourceProvider at runtime, RadPivotFieldList does not refresh unless I change the ItemsSource (by setting it to null and back to the previous items source). Is there any other way to refresh the list?

2) Is there a way to automatically expand Container Nodes in RadPivotFieldList? I tried using an implicit style targeting TreeGridRowGroupHeader but it is not working.

Thanks,

Hello ,

             I am new to telerik tool and upgrading the old asp.net application to WPF browser application which extensively uses the grid view control.

             I am trying to replicate following functionality from old application to new application and not sure what is the best approach and how to do it .

             1.Grid view is binded to database object and  based on the certain value present in particular field I need to show the edit button in each row, If that value    is not present then I need to hide the button.

             2. On click of this edit button, I need to show the update and cancel button in place of edit button as well as show the combo box with selections in different column (only this column need to be editable).

Thanks

Hi,

I'm trying to pass the window object of a window type RadWindow as command parameter to the code behind - however not RadWindow will be passed, but some helper windows classes of type WindowHostWindow.

The XML look like this:

<telerik:RadRibbonButton Text="Speichern"
                                             AllowDrop="True"
                                             LargeImage="..\Images\save.png"
                                             Size="Large"
                                             telerik:ScreenTip.Title="Speichern"
                                             telerik:ScreenTip.Description="Einen neuen Task anlegen."
                                             telerik:KeyTipService.AccessText="S"
                                             IsEnabled="{Binding CanSave}"
                                             Command="{Binding SaveCommand}"
                                             CommandParameter="{x:Reference Name=taskwindow}"
                                             IsDefault="True"/>

The Code behind(implementation of the command):

private void SaveProcess(object obj)
{

...

RadWindow wnd = (RadWindow)obj; <= this cast already fails as some helper class will be passed instaed of the expected RadWindow

Using the "normal" Window class instaed of the Telerik one, the code runs without any issues.

Looking forward to your answer.

Thanks,

Joachim
