Hi Telerik Team!!

Sorry to bother you, but one more time I have an issue :S,

I have a RadGridView and one of the columns has a datatemplate (button), i.e. if I select the row 1 and after I click the button from the row 5, the  row 1 keeps selected.

<

 

 

telerik:GridViewDataColumn Header="title" >

 

 

 

 

    <telerik:GridViewDataColumn.CellTemplate>

 

 

 

 

        <DataTemplate>

 

 

 

 

            <telerik:RadButton Content="{Binding Value}"

 

 

 

                Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}},

 

 

 

                Path=DataContext.X}"

 

 

 

                CommandParameter="{Binding Number}"/>

 

 

 

 

        </DataTemplate>

 

 

 

 

    </telerik:GridViewDataColumn.CellTemplate>

 

</telerik:GridViewDataColumn>

Thanks.

 

Hi Telerik Team.

I have a problem with the rows using the RadGridView and implicit styles, I'll explain:

I have a RadGridView and when it is loaded and I click over a columns name to sort the rows everything is ok, the problem
arise when I added a rowstyle to highlight rows which contain specific data.

 

<

 

 

telerik:RadGridView.RowStyle>

 

 

 

 

    <Style TargetType="telerik:GridViewRow" BasedOn="{StaticResource GridViewRowStyle}">

 

 

 

 

        <Style.Triggers>

 

 

 

 

            <DataTrigger Binding="{Binding Status}" Value="2">

 

 

 

 

                <Setter Property="Background" Value="Red"/>

 

 

 

 

            </DataTrigger>

 

 

 

 

        </Style.Triggers>

 

 

 

 

    </Style>

 

 

 

 

</telerik:RadGridView.RowStyle>

After add those lines when I click over the column name to sort, the rows disappear.

Please any help is really helpful. Thanks.

 

Hi,

Ever since upgrading to the latest release of the WPF libraries (Q2 2012) I am experiencing issues with the currency format in my RadGridView. My PC is set to en-GB but the application was reporting values back in en-US.

I managed to overcome the issue by setting the following code in each of my windows & pages:



However, I have just stumbled across another issues.
I have a radgridview hosted in a RadDocking pane. When the pane is docked the currency reported in my cells are as they should be, en-GB (£). When the pane becomes floating, the grid cells switch back to en-US ($).

Do you know how I can prevent the culture of my pane from switching when it becomes floating?

Thank you for your time,

Rob

Hi,

We would like to implement a spin progress bar (see the attached image) into Tabs, Toolbars etc.
Could you give us info whether you have any or similar solution to this control in WPF?

Thanks,

Is there any easy way to center a diagram? I believe I may need to use the align feature, but not 100% sure.

I've been using autofit and that centers it however when exporting to an image, even with the bounds set for the entire viewport it doesn't export in the center.

Any ideas on what I can try?

Hi,
Am having some issues with the Dropdown content in RadDropDownButton.
I get multiple instances of the dropdown content (attached screen shot).
Below is my xaml.

<telerik:RadDropDownButton AutoOpenDelay="0:0:0.0" Grid.Column="1" Grid.Row="0" FlowDirection="RightToLeft" DropDownButtonPosition="Left" 
                                                       Visibility="{TemplateBinding SearchHistoryListVisibility}" KeepOpen="False" DropDownMaxHeight="170"
                                                       IsOpen="{Binding IsSearchHistoryOpen, Mode=TwoWay}">
                                    <telerik:RadDropDownButton.DropDownContent>
                                        <Grid>
                                            <Grid.ColumnDefinitions>
                                                <ColumnDefinition Width="{Binding SearchHistoryWidth}" />
                                            </Grid.ColumnDefinitions>
                                            <ListBox Grid.Column="0" FlowDirection="LeftToRight" 
                                                     ItemContainerStyle="{StaticResource SearchHistoryItemStyle}" BorderThickness="0.25" BorderBrush="DarkGray"
                                                     ItemsSource="{Binding Path=SearchHistoryList}" 
                                                     SelectedValue="{Binding Path=SelectedSearchQuery, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" 
                                                     HorizontalAlignment="Stretch" />
                                        </Grid>
                                    </telerik:RadDropDownButton.DropDownContent>
                                </telerik:RadDropDownButton>

Am trying to close the dropdown content on click of a listbox item. Am setting  IsSearchHistoryOpen=false from SelectedSearchQuery property.

This happens only when I specify Mode=TwoWay in IsOpen="{Binding IsSearchHistoryOpen, Mode=TwoWay}".
But if I dont specify the twoway mode, the dropdowncontent doesnt close when i click the listbox item.

Any help is much appreciated.

Thanks

I'm trying to dislpay a text informing the user that more items are loaded on the background of the tree view. I am trying to change the template. As soon as the ItemsPresenter is not a direct child of ScrollViewer the tree stops displaying the items.

Here is my template:

    <ControlTemplate x:Key="RadTreeViewWithLoadingTemplate" TargetType="{x:Type telerik:RadTreeView}">
        <Grid x:Name="RootElement">         
            <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}">
                <Grid>
                    <ScrollViewer x:Name="ScrollViewer" BorderThickness="0" Background="{x:Null}" CanContentScroll="True" HorizontalScrollBarVisibility="Auto" IsTabStop="False"
                                  Padding="{TemplateBinding Padding}" VerticalScrollBarVisibility="Auto"
                                  Style="{DynamicResource LoadingScrollViewerStyle}">
                        <Grid>
                            <Grid.RowDefinitions>
                              <RowDefinition Height="Auto" />
                              <RowDefinition Height="*" />
                            </Grid.RowDefinitions>
                            <ItemsPresenter/>
                            <TextBlock Text="Loading more items!" Height="20" VerticalAlignment="Center" HorizontalAlignment="Center" Grid.Row="1"/>                       
                    </ScrollViewer>
                    </Grid>
            </Border>
        </Grid>
    </ControlTemplate>

Thanks,

Hi

With release .Net version 4.0 of wpf diagram, we have overrided the OnPositionChanged to prevent the user to move the chart to the left and upward compared to the position (0,0).   If the coordinates of the diagram exceed the point of origin, the position is reset to the origin point.  Ex.: (10, -10) is converted into (0, -10).
 
We have updated our solution with the beta 4.5 and the behavior has changed. It is impossible to change the Position property of the diagram in the method "OnPositionChanged."

I attache a sample project. The source code is in the class "MyDiagram." Download project here

Could you restore the original behavior or offer a solution?

Sincerely,

    protected override void OnPositionChanged(Point oldPosition, Point newPosition)

    {

        base.OnPositionChanged(oldPosition, newPosition);

        Point newPoint = newPosition;

 

        if (newPosition.X > 0)

        {

            newPoint.X = 0;

        }

        if (newPosition.Y > 0)

        {

            newPoint.Y = 0;

        }

        //With the 4.0 DLL version, there is no problem to set the new position

        if (newPoint != newPosition)

        {

            this.Position = newPoint;

        }

 

        if (newPoint != newPosition)

        {

            //With the 4.5 DLL version, I need to invoke the method to get the same behaviour

            //but the diagram flikers

            Dispatcher.BeginInvoke(new Action(() =>

                                                  {

                                                      this.Position = newPoint;

                                                  }), DispatcherPriority.Render);

        }

 

        sh.SetText(((int)this.Position.X).ToString("") + "  -  " + ((int)this.Position.Y).ToString(""));

    }

}

It is not clear to me how one would go about virtualizing vertically.

For example, if one has many possible "groups" in a scroll viewer which are controlled by a single slider they would not want to materialize all of the UI elements.  Subsequently if the query could be broken up by group, they would not want to query the records for all of the groups.

Any ideas or examples out there?
