Hello,

I would like to add support to my RadDiagram for the user to perform a multi-select operation using the Shift key, in addition to the default Ctrl key.  I looked at adding to the InputBindings but there is no Command for select.  I also tried adding a handler for OnSelectionChanged that attempted to re-select the items in the SelectionChangedEventArgs.RemovedItems but my changes were apparently overridden after the handler completed and only the last clicked item would be selected.

Is there a way to implement this?

Thanks,

This is for WPF ChartView. I am trying to Sync the track ball move of one chart to show up in another chart. I am displaying two different sets of information in both charts, but since the X-Axis has the same value for both, I need to Sync the move on one chart and see the result in the other chart. I am attaching a screenshot to explain better. Any Idea, how I can accomplish this. I know I have to trigger the  CharTrackBallBehavior_TrackInfoUpdated event somehow, but as far as I can see in other threads it's not possible to trigger that event manually. Any Other ideas on how I can accomplish this?

Hi,

Could you please advise how to reference the row(s) of the SelectedCells?

For example, would like to implement a "copy down/fill handler" (as in Excel) using a ContextMenu on the gridview. For each SelectedCell, we would like to copy the cell contents of the top selected row down to each row of the SelectedCells using MVVM. Please find a sample of the XAML attached.

        <telerik:RadGridView Name="dtgMyData" 
                             ItemsSource="{Binding Path=MyData}" 
                             AutoGenerateColumns="False" 
                             RowIndicatorVisibility="Visible"
                             HorizontalAlignment="Stretch"
                             SelectionMode="Extended"
                             SelectionUnit="Mixed">

...

<telerik:RadMenuItem Header="Copy Values Down" Command="{Binding DataContext.CopyValuesDownCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:RadContextMenu}}}" CommandParameter="{Binding Path=UIElement, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=telerik:RadContextMenu}}" />
                    </telerik:RadContextMenu.Items>
                </telerik:RadContextMenu>
            </telerik:RadContextMenu.ContextMenu>

...columns...

</telerik:RadGridView>

 

Kindly advise.

Thanks

I found a strange behaviour:

  1. Open a document.
  2. Copy a text.
  3. Paste.
  4. Undo.
  5. Redo.

Redo command works but also select all document content. Why? How can I avoid it?
It happens only with paste: all other redo commands haven't this behaviour.

Thank you.

Our application uses RadMaskedTextInputs for user data input. When Enter is pressed, we perform field validation and focus the fields that need revising. If however two of these controls are focused one after the other, the application freezes. To test try the following:

Create a WPF with two RadMaskedTextInputs

    <Grid>
        <telerik:RadMaskedTextInput Width="100" Height="20" Margin="200,122,0,167" Name="txt1"></telerik:RadMaskedTextInput>
        <telerik:RadMaskedTextInput Width="100" Height="20" Margin="200,155,0,134" Name="txt2"></telerik:RadMaskedTextInput>
    </Grid>

On txt2 keyup event:

    Private Sub txt2_KeyUp(sender As Object, e As System.Windows.Input.KeyEventArgs) Handles txt2.KeyUp
        If e.Key = Key.Enter Then
            txt1.Focus()
            txt2.Focus() 
        End If
    End Sub

Run the application, type something in txt2 and press enter.

Regards

We would like to click a row and show only the DETAILS row, not the "original" row.  Please see attached files for clarity.

The main idea here is "Less is More". I don't want essentially 2 rows of information when I select a particular row.

If the user exits the DETAILS row (either by clicking another row or activates another window) then the row returns back to its normal state.

Thanks in advance!!!

Hi,
I Use a RadDataPager in Unbound Mode.
when I want to set ItemCount to a big number (for example 450000000),
it takes almost 20 second.
is any way to improve time?
Thanks.
