I'm using the RadGridView with a dynamic object binding in order to show a grid of business objects (rows), each with properties (columns). The properties are not known before the business objects are selected.

Each property has its own viewmodel and related DataTemplate.

The GridCellPropertyContainerViewModel we are using for each grid cell encapsulates the relevant PropertyContent, so its DataTemplate uses a ContentControl, like so:

In my code-behind for the following XAML fragment, I would like to do "MyTextBox.Focus()", but MyTextBox is not accessible. Is there a way I can access it?

    <Grid>
        <telerik:RadPropertyGrid Item="{Binding}"
                                 RenderMode="Flat"
                                 AutoGeneratePropertyDefinitions="False"
                                 DescriptionPanelVisibility="Collapsed"

                                 FieldIndicatorVisibility="Collapsed"
                                 Loaded="RadPropertyGrid_Loaded"
                                 LabelColumnWidth="150">
            <telerik:RadPropertyGrid.PropertyDefinitions>
                <telerik:PropertyDefinition DisplayName="Text"
                                            GroupName="Text Properties"
                                            OrderIndex="0">
                    <telerik:PropertyDefinition.EditorTemplate>
                        <DataTemplate>
                            <TextBox x:Name="MyTextBox"
                                     TextWrapping="Wrap"
                                     AcceptsReturn="True"
                                     AcceptsTab="True"
                                     Height="60"
                                     VerticalContentAlignment="Top"
                                     Text="{Binding Text, UpdateSourceTrigger=PropertyChanged}"/>
                        </DataTemplate>
                    </telerik:PropertyDefinition.EditorTemplate>
                </telerik:PropertyDefinition>
            </telerik:RadPropertyGrid.PropertyDefinitions>
        </telerik:RadPropertyGrid>

Hey,

how can I adjust position of pasted element on diagram? Currently it's exactly in the same place as the copied element and it should be better to slightly move it to the right and down, so user will see the copy-paste action actually completed.

Any ideas?

Hi, i have massive problem.

If you only run the image editor, it works fine.

However, when i load an image editor from another program, i can not see the component values. Please check attached file.

Please i need your help. 

I look forward to your feedback.

Thanks

Few of our customers sometimes experience the exception above (I assume it doesn't always happen to them), and we get the crash report through our diagnostics system.

The problem looks like coming from:

Are you aware of issues that can cause it?

Thanks.

I've got a slider bound to a double property.  The double property controls the opacity of a shape right next to my control

When I drag the center thumb with the mouse, everything works perfectly.  The opacity changes in 0.01 increments, the tooltip updates and the opacity changes.  It does all of this smoothly.

When I try to drag that same thumb via touch, it just doesn't work.  It basically seems to go from 0 to 1.  Even if I set both small and large change to 0.01 and disable SnapToTicks (it has no effect). It won't drag smoothly.  I've even tried styling the thumb to make it use a very large size (just to be sure it's not me missing it with touch).  Still doesn't work.

What property do I have to set to make the slider change smoothly with touch as it does with the mouse?

I've attached an image of me dragging the center slider with the mouse where it's working perfectly.  

Here is my XAML

Hello

I use the RadScheduleView (Version 19.2.510) and have two questions regarding the appointment-editing window.

1) Can the window for the definition of the rule of an appointment repetition be called independently of the ScheduleView (for example, if you want to call the menu item "Edit rule" in a list of appointments)?

2) Is it possible to use your own window to edit an appointment, independent of the ScheduleView and with your own ViewModel?

Thanks

Hi all,

we are using RadGridView version 2016.2.613.45 (.NET 4.5,  Visual studio 2017, C#) and are having issues with this functionality:

https://docs.telerik.com/devtools/wpf/controls/radgridview/filtering/how-to/howto-customize-the-default-field-filter-editor#filter-as-user-types

Basically, we have implemented a functionality to perform the filtering on every change(key press) in the filter bar.

However, we found a small issue(not to say a bug :) ).

When the filter mode is set to "RowFilter", and user is performing a filtering on numeric column, he is not able to type in the dot character(.).

The only way to get the dot in the filter is to type in the number and afterwards put the dot where you need it.

Example: trying to search for the number 556.32 you would need to type in the 55632 and afterwards place the dot where it needs to be.

This is only manifested when the filtering is set to trigger every time a user types. If we disable the functionality(remove the implementation), it works fine.

The implementation:

XAML:

In the code behind, we simply attach to the appropriate event:

this.radGridView.FieldFilterEditorCreated += WPFDataGrid_FieldFilterEditorCreated;

and in the "WPFDataGrid_FieldFilterEditorCreated" method we do:

Any help would be appreciated.

Regards,

Igor

Hello.

Can I access SearchPanel DataContext from another part of Template?

I have a HightLightningTextBlock Class that I want to use instead of the HighLightTextBlock used in DataColumn. I use a DataTemplate:

I asign the DataTemplate when adding a column:

I want to bind the "HighlightText" property to the "SearchText" of "PART_SearchAsYouTypeTextBox". The "Text" property works well. I use the HighlightingTextBlock because I want to change the background instead of the foreground when type in search box.

Thank you.
