Hello.

I think i found some bug when using RadSlider control.

When I create new RadSlider with IsSelectionRangeEnabled set to true and then move slider so that I create some range and then when I click on slider (like when i would want to move with range but i don't move it only mouse click on it) then it is somehow bugged...

After this it is not possible to move with left slider (selection start value).
Actually when I try to move left (minimum) slider, visually nothing happens but on each mousemove event SelectionStart is increased or decreased (depens wheather I move with mouse on left or on right from left slider position) until it is same as SelectionEnd or same as minimum slider value.

I hope you can understand what I mean . (it is easy to reproduce when slider is on maximum range)

I created my slider in code like this:

RadSlider testSlider = new RadSlider();
testSlider.Minimum = -20;
testSlider.Maximum = 40;
testSlider.Orientation =
Orientation.Horizontal;
testSlider.IsSnapToTickEnabled = true;
testSlider.IsSelectionRangeEnabled =
true;
testSlider.TickPlacement = Telerik.Windows.Controls.TickPlacement.None;
testSlider.TickFrequency = 1;
testSlider.SelectionStart = 0;
testSlider.SelectionEnd = 5;

testSlider.Width = 240;
Canvas.SetLeft(testSlider, 10);
Canvas.SetTop(testSlider, 10);
aMainCanvas.Children.Add(testSlider);

I'm in the middle of producing a new WPF app to replace an old Clipper application for one of my clients.  So I'm trying to develop a window framework for basic business objects.  I'm trying to build a generic user control which can facilitate the typical <First> <Prev> <Next> <Last> record navigation within a TabControl.  The first tabs are my RadGridViews which allow for sorting and searching capability.  The second tab is a details tab, which is where I would like to have this record navigation so the end user doesn't have to go back and forth between the tabs if they're just trying to move through the list.

I have the navigation working just fine but I would like to add a couple textboxes to the user control which would display the current record # and the total # of records.  I don't want to tightly couple the user control to the specific grid or page.  My user control is "bound" to the grid during the constructor method of the window.  I can easily get the current record during the click event of each of the 4 buttons but would prefer if the user control would update on any movement on the grid.  Also, I would like to have a user control property bound to the population of the grid data so the user control would know whenever a new search if performed within the grid and appropriately reset the two text boxes.  I'm just not quite sure how to do this and what event or property of the RadGridView I'd tie it to.  I'm new to WPF and C# so my guess would be some type of CommandBinding or DependencyProperty?

Any help would be greatly appreciated.

Thanks,
-Sid Meyers.

Hi, I've a problem with the SelectedItem property.
I set ItemsPerPage = 3

The databinding is OK, so I can scroll any element in the collection

But, when I try to do this:

this

 

.sampleCarousel.SelectedItem = this.sample.Items[index];

if the Item isn't in the view the Carousel doesn't update its view...

For example if the SelectedItem corresponds to item 3 in the collection and I do this

this.sampleCarousel.SelectedItem = this.sample.Items[1];

The carousel view doesn't update

Where is the problem?
Thanks in advance,
Manuel

Hi
I added three additional columns to the grid, then bound to my datasource (Nothwinds ado entities)

 Public Sub New()  
        MyBase.New()  
 
        Me.InitializeComponent()  
 
        ' Insert code required on object creation below this point.  
        
        gv1.AutoGenerateColumns = False 
        Dim detailDefinition As GridViewTableDefinition = New GridViewTableDefinition()  
        detailDefinition.Relation = New PropertyRelation("Orders")  
        gv1.TableDefinition.ChildTableDefinitions.Add(detailDefinition)  
 
        Dim gvdc As GridViewDataColumn  
 
        gvdc = New GridViewDataColumn  
        gvdc.HeaderText = "One" 
        gvdc.EditorSettings = New ComboBoxEditorSettings  
        gv1.Columns.Add(gvdc)  
 
        gvdc = New GridViewDataColumn  
        gvdc.HeaderText = "Two" 
        gvdc.EditorSettings = New CheckBoxEditorSettings  
        gv1.Columns.Add(gvdc)  
 
        gvdc = New GridViewDataColumn  
        gvdc.HeaderText = "Three" 
        gvdc.EditorSettings = New DatePickerEditorSettings  
        gv1.Columns.Add(gvdc)  
 
        CustomerList = (From c In _cx.Customers.Include("Orders")).ToList  
        Me.gv1.ItemsSource = CustomerList  
 
        _CurrentCustomer = CustomerList(0)  
    End Sub 
 

clicking on and off column "Three" (DatePickerEditor), after the grid has rendered, causes this exception

Hi

If there is an validation error on the editable cell, I set a style, in code, for that cell like so:-
 Private Sub gv1_PreviewValidate(ByVal sender As System.ObjectByVal e As Telerik.Windows.Controls.GridView.Cells.CellValidatingRoutedEventArgs)  
        If e.NewValue = String.Empty Then 
            e.ValidationResult = New Telerik.Windows.Controls.GridView.ValidationResult(FalseNothing)  
            DirectCast(DirectCast(e.OriginalSource, System.Object), Telerik.Windows.Controls.GridView.GridViewCell).Style = Me.FindResource("ContentControlStyleError")  
        Else 
            e.ValidationResult = New Telerik.Windows.Controls.GridView.ValidationResult(TrueNothing)  
            DirectCast(DirectCast(e.OriginalSource, System.Object), Telerik.Windows.Controls.GridView.GridViewCell).Style = Nothing 
        End If 

and the style is

 <Style x:Key="ContentControlStyleError" TargetType="{x:Type telerik:GridViewCell}">  
            <Setter Property="Template">  
                <Setter.Value> 
                    <ControlTemplate TargetType="{x:Type ContentControl}">  
                        <Border Width="110" Height="55" BorderThickness="2,2,2,2" CornerRadius="10,10,10,10" BorderBrush="#FF000000" RenderTransformOrigin="0.5,0.5">  
                            <Border.RenderTransform> 
                                <TransformGroup> 
                                    <ScaleTransform ScaleX="1" ScaleY="1"/>  
                                    <SkewTransform AngleX="0" AngleY="0"/>  
                                    <RotateTransform Angle="17.431"/>  
                                    <TranslateTransform X="0" Y="0"/>  
                                </TransformGroup> 
                            </Border.RenderTransform> 
                            <Border.Background> 
                                <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">  
                                    <GradientStop Color="#FF000000" Offset="0"/>  
                                    <GradientStop Color="#FFDC1D1D" Offset="1"/>  
                                </LinearGradientBrush> 
                            </Border.Background> 
                            <ContentPresenter   
                                        VerticalAlignment="Center"   
                                        HorizontalAlignment="Right"   
                                        Margin="0,0,10,0"   
                                        TextBlock.Foreground="White"  /> 
                        </Border> 
                    </ControlTemplate> 
                </Setter.Value> 
            </Setter> 
        </Style> 
now I know this style is awful, but it is the principle I am after.

When I set this style in code, the entire grid cells are no longer editable, also, if I scroll the grid so the offending cell is out of view, then scroll it back into view, the style has disappeared.

Any thoughts why this is happening?


Thanks

Hello,

Presntly we are evaluating the RadGridView for the WPF, we are planning to use it in near future. We have some queries regarding the GridView, I will be helpful if you reply the queries with yes/no.

1 Does it provide configurable keyboard
and mouse edit commands.
2
Does it provide Excel-like default keyboard and mouse edit behavior, including F2, Esc (cancel edit on a cell and restore the original value), Double-Esc (cancel edit on the entire row and restore the original values), and Enter.
3 Can the Cell editors displaye without entering edit mode, under a variety of conditions such as a mouse hover over the cell or row, the cell or row becoming current, the row being edited, or always.
4 Automatically selects the appropriate editor control depending on the field data type.
5 Manages “null” and “DbNull” values.
6 Any portion of the grid can be made read-only.
7 Custom grouping in grid and details supported or not. Supports hierarchical, multi-level grouping in all views.

8
Supports UI virtualization, preserving memory and reducing load time, even when grouping.
9 2D and 3D Card View
10 Row margin selects and resizes rows, and displays icons indicating that the row is current, is being edited, is an insertion, or has a validation error
11 Automatically changes a row’s height to fit the contents of the largest cell.
12 Supports error style when Validation throws an exception when trying to leave edit mode.Includes built-in data validation, at the cell or row level.
Wether Error display  integrated with the included views
13 Editor Controls Support:
CheckBox.
AutoSelectTextBox.
DatePicker/Calendar.
ValueRangeTextBox.
NumericTextBox.
MaskedTextBox.
DateTimeTextBox.

IPAddressMaskedTextBox.
PhoneMaskedTextBox (North American format).
Simple CurrencyMaskedTextBox.
ExponentNumericTextBox.
DateTimeTextBox (with ShortDate, ShortTime, ShortDateAndShortTime, and ShortDateAndLongTime formats). 
14 Does it support Data virtualization (sometimes called “virtual mode” or “lazy loading”) vastly improves performance and reduces memory usage, especially when working with large data sources.
15 Can it automatically obtain and synchronizes bound data from any .NET source, including jagged arrays, any object that implements IListSource or IList, and any ADO.NET DataSet, DataTable, DataView, or DataViewManager object.
16 Can it intercept, parse, and modify data being synchronized with the database from the grid
17 Excel export of grid contents, including groups, detail content, and statistical functions (formulas and values), using XMLSS or CSV.

Thanks and Regards

I would like to have a grid with a button on each row that when pressed launches another window; the handler will have to know the contents of one of the data fields on the row (the pk) in order to display the new window. Based on the outcome of this process the user may or may not check a checkbox on that row that is not bound to data. There will be a button on the window outside of the grid that when pressed will run another process on all rows that have the checkboxes checked. I would also like to have buttons external to the grid that will check or uncheck all of the checkboxes. I have searched the examples and documentation and cannot find out how to determine the PK of the row when the button is pressed nor a way to iterate through the rows and process the ones with the checkbox checked. Some sample code would be appreciated as I'm new to WPF.

Hi,

I've got a little question.

When i've got a lot of rows in my grid and i want to do scrolling using the scrollbar my cpu usage jumps to 80% or more until i stop scrolling!

Same happens with the fade effect when i hover over rows, then my cpu jumps to 60% or more until is stop hovering.

Do you have any explication or solution for this?
