Hi there,

I'd like to know if you can use an ivalueconverter in a textcolumn, or if not, how you can use the filter menu of a textcolumn in a templatecolumn?
On a related note; can you also use a converter on the grouping header?

Bit of background, for further clarity:
I'm trying to create a program that displays a list of files, their names and things like their last edited dates.
As such my datasource is a list(fileinfo).
To display the filenames in a user friendly manner I'd like to trim the directorynames a bit.
I know how to do this using a templatecolumn, but then I lose the nice filtering menu that's built into the textcolumn. 

<telerikGrid:RadDataGrid x:Name="DataGrid" SelectionUnit="Row">
            <telerikGrid:RadDataGrid.Resources>
                <Style TargetType="gridPrimitives:SelectionRegionBackgroundControl">
                    <Setter Property="Background" Value="Red"/>
                    <Setter Property="BorderBrush" Value="Green"/>
                    <Setter Property="BorderThickness" Value="2"/>
                </Style>
            </telerikGrid:RadDataGrid.Resources>
        </telerikGrid:RadDataGrid>

 

this.DataGrid.ItemsSource = new List<Data>
 {
     new Data { Country = "India", Capital = "New Delhi"},
     new Data { Country = "South Africa", Capital = "Cape Town"},
     new Data { Country = "Nigeria", Capital = "Abuja" },
     new Data { Country = "Singapore", Capital = "Singapore" }
 };

 

public class Data
    {
        public string Country { get; set; }

        public string Capital { get; set; }
    }

 

When I select one row, the SelectionRegionBorder Control  doesn't work.

Hello,

In my datagrid, I use a custom DataTemplate for one of my (autogenerated) columns:

 

The above works perfectly. Both properties StatusColor and Title are used in one custom formatted cell.

My questions:

• I have been unable to use a binding converter to modify the appearance of the data to be displayed

For example like this:

Having myColorConverter well defined and accessible in myNS.Converters. I have tried to add the static resource in the DataTemplate, or in the grid resources or even in the top page xaml resources, but each time I get "resource could not be found". 

How can I use a Binding Converter in this situation ?

 

• I have been unable to attach an event to any of the template's Element. The goal is to navigate to a new frame of the application when the user taps the generated cell above.

For example like this:

My code behind would of course contain an event handler like this:

But that never gets fired. And I would expect it to fail anyway because my grid has multiple rows and thus I get multiple times the same TextBlock name ; meaning I need to attach an event handler, but how, and at which moment in the page lifecycle ?

I have also tried to use the CellTap DataGridCommand, but when I use 

the last line throws a Memory Violation Exception.

How can I register an event ? How can I navigate to a new frame ?

 

Thanks for any help

Currently, I'm implementing a DataGrid with the SelectionMode set to Multiple and I noticed that the way you select multiple rows is to just click on each one. This is not really a problem when you only need to select a few rows but when selecting 10 or 20 rows this can become time-consuming. Is there a way I can change the selection method to be closer to the traditional Windows method of multiple ? Like using ctrl to select rows individually and shift to select a large group. Thanks in advance for any help.

Hello

I just do not get any further. I have two questions.

 

1. I have the problem that I want to set after the call of "BeginEdit ()" the focus on the first texbox?.

2. How can I jump to the next textbox with Enter like the TAB key?

 

Thank you

I hope my english is sufficient

Hi there,

is it possible to avoid horizontal scroll bars and let the RadDataGrid use the available space only?

Thanks, Alexander

I have a column in a table that contains an integer which is related to the primary key integer in another collection. In the column instead of displaying the integer, I am trying to display the Name field from the related collection in the grid column. Right now it displays the integer instead of the expected value from DisplayMemberPath.  (The combobox is working as expected when in edit mode.) There are no errors in XAML designer, build process or in debug immediate window. I have tried a number of tweaks and all the docs I can find but nothing has worked. Seems strange combo is working exactly as expected during edit mode but DisplayMemberPath won't show in grid view mode.

I have a Data grid that looks like so:

 

The Time column shows the correct sort direction indicator but when the data changes (Notes is an ObservableCollection) it is not sorted automatically. Do I have to pre-sort the data I added to Notes?  This seems a bit redundant.

I want to change Accent Color of RadDataGrid which is blue, on changing SystemAccentColor datagrid's accent color is not changing. 
How to Change that color mentioned in ScreenShot, wherever blue color is used throughout all the DataGrid's operations.

 

Thank you.

Hello,

There is a RadDataGrid with couple of DataGridTemplateColumns. One of the column contains a MediaPlayerElement as a video preview.

The realized problem is when I am changing any column's size, the grid and all of the contained element's bindings are automatically read again. It causes a couple of error (and ugly behavior) on the MediaPlayerElement, the rest of the columns are working fine.

 

The Grid:

        <telerikGrid:RadDataGrid x:Name="GridVideoFiles" Grid.Row="1" UserEditMode="External" AutoGenerateColumns="false" UserFilterMode="Disabled" UserGroupMode="Disabled"
                                 ColumnResizeHandleDisplayMode="Always"
                                 DragOver="UIElement_OnDragOver" AllowDrop="True"
                                 Drop="UIElement_OnDrop"
                                 ItemsSource="{Binding VisionFiles}">

The given column:

                <telerikGrid:DataGridTemplateColumn Header="Video Player" SizeMode="Fixed" Width="300" CanUserResize="False">
                    <telerikGrid:DataGridTemplateColumn.CellContentTemplate>
                        <DataTemplate>
                            <Grid Width="300">
                                <MediaPlayerElement Width="300" Source="{Binding Media, Mode=OneTime}" AreTransportControlsEnabled="True">
                                    <MediaPlayerElement.TransportControls>
                                        <MediaTransportControls IsCompact="True"/>
                                    </MediaPlayerElement.TransportControls>
                                </MediaPlayerElement>
                            </Grid>
                        </DataTemplate>
                    </telerikGrid:DataGridTemplateColumn.CellContentTemplate>
                </telerikGrid:DataGridTemplateColumn>

 

Can you tell me any solution to prevent the binded Media property updating automatically?
