Currently, I'm trying to use Drag/Drop in my application however none of the events in relation to this are firing. Is this a known issue? If so, are there workarounds?
I've also tried to use ItemDoubleClick even which is also not getting fired.
Please do let me know.
TIA

I am going to use the footer to sum all values.
<telerik:GridViewDataColumn.AggregateFunctions> <telerik:SumFunction ResultFormatString="{}{0:C2}"/> </telerik:GridViewDataColumn.AggregateFunctions>There are many columns, one of them I want to set the foreground color as Red.(Not all columns, just one important column)
First question: How to do it?
Second question: I saw the bottom border line of the footer is gone. Why?
Thanks

Hi everyone!
I use a Version 2015.1.401.40 GridView to show entries with a bool value. I want to show only entries with the bool value 'false', but keep the possibility to look at the other entries too.
So I created a Behavior for the GridView:
private RadGridView Grid { get => AssociatedObject as RadGridView; } protected override void OnAttached() { base.OnAttached(); Grid.DistinctValuesLoading += Grid_DistinctValuesLoading; Grid.FilterOperatorsLoading += Grid_FilterOperatorsLoading; } private void Grid_DistinctValuesLoading(object sender, GridViewDistinctValuesLoadingEventArgs e) { e.ItemsSource = new List<bool>() { true, false }; } private void Grid_FilterOperatorsLoading(object sender, FilterOperatorsLoadingEventArgs e) { IColumnFilterDescriptor okFilter = Grid.Columns["IsStandinSetupOK"].ColumnFilterDescriptor; okFilter.SuspendNotifications(); okFilter.DistinctFilter.AddDistinctValue(false); okFilter.ResumeNotifications(); }
And as expected only entries with the IsStandinSetupOK value 'false' are shown. But that filter is not indicated by the Icon, and the filter menu looks like there is no filter active (see screenshot). Even clicking 'Clear Filter' does nothing, to remove the filter I have to activate either the true or false filter first, THEN click 'Clear Filter'.
The GridView is filled with entries only after the filter was applied.
Any idea what I did wrong?
Best regards,
Stefan

Hi,
I have a problem showing the right editor für the properties for items inside a collection.
For RadPropertyGrid.Item I set a collaction.
The items of the collection has some EditorAttribtes set.
But at the ProbpertyGrid the Attribute is ignored.
Is there anything I can do to get this working?
private void Grd_OnSelectedCellsChanged(object sender, GridViewSelectedCellsChangedEventArgs e) { PropGrid.Item = new List<Test> {new Test {Name = "N1", Number = 1}, new Test {Name = "N2", Number = 1}}; }public class Test{ public string Name { get; set; } [Telerik.Windows.Controls.Data.PropertyGrid.Editor(typeof(TextBlock), EditorStyle.Modal)] public int Number { get; set; }}
Hi,
Is there a way that I can configure the selection for the TileList, so that, the user can select multiple tiles but only one tile per group?
Like the behavior of a RadioButton, for example?
Thanks in advance.
Hi,
I've been dealing with this problem for days without being able to find a solution. Here is the thing, if I put a Telerik control, say RadTabControl, in a UserControl ("UserControl A"), I can edit it with the VS designer without any problem. If I put UserControl A into another UserControl ("UserControl B"), I can see and edit UserControl B as long as I keep the designer window open. If I close the designer window and open it again, the designer would not load, and throws an exception complaining that it cannot create an instance of UserControl B. The exception hierarchy looks like this:
Exception: Cannot create an instance of "UserControl B"
- TargetInvocationException: Exception has been thrown by the target of an invocation.
-- XamlParseException: 'Provide value on 'System.Windows.StaticResourceExtension' threw an exception.' Line number '19' and line position '20'.
--- Exception: Cannot find resource named 'Telerik.Windows.Controls.RadTabItem'. Resource names are case sensitive.
Please help me! Thanks in advance.

Hello
how can I set custom color to the HeaderBackground property of the RadLayoutControl (LayoutControlExpanderGroup)?
I tried similar way for setting implicit styles mechanism like setting the HeaderBackground of RadLayoutControl, but this not work:
<Style TargetType="telerik:RadLayoutControl" BasedOn="{StaticResource RadLayoutControlStyle}"> <Setter Property="HeaderBackground" Value="Yellow" /></Style>
It can not be difficult, but I do not find anything in the documentation.
Thanks for any help.

Hi, right now I'm using the WPF GridView, and have the filter row turned on. I've turned off the filtering panel and instead selected a default filter for the user to make it simple. But my problem is that if a user has their cursor in the first filtering textbox and they hit the "tab" button, it selects the next filtering cell, rather than the next filtering textbox. They're essentially having to press tab twice to move from filter textbox to filter textbox.
I saw the "TabStopMode="Skip"" but that seems to only apply to the actual cells of the gridview, not the filter row. So how do I prevent having to double tab in the filter row?

Telerik Team,
I have a customer who has assigned many items to their QuickAccessToolbar. So many so that there are more than can be displayed on the screen at one time. The remaining items get put into the overflow panel that is accessed by clicking the RadRibbonDropDownButton. This customer prefers to access these QuickAccessToolbar items with their keyboard, so they press left-alt to bring up the AccessText. I have figured out through code how to add AccessText to the drop down button, but I can't figure out how to then have the items in the overflow window display their access keys automatically when the overflow window is opened and be available for selection.
Here is how I am assigning the AccessKey to the drop down. I would prefer to do it in xaml if possible, but I couldn’t figure that out.
private void RadRibbonView_Loaded(object sender, RoutedEventArgs e){ var ribbon = sender as RadRibbonView; var qat = ribbon.QuickAccessToolBar; var dropDownButton = qat.FindChildByType<RadRibbonDropDownButton>(); if (dropDownButton != null) { KeyTipService.SetAccessText(dropDownButton, "00"); }}We are using the 2015.3.930.40 (No XAML) version of your controls.
Any help would be appreciated.
Thanks,
Paul
Hi,
I want to show the values and the pen names at the cursor location for all my lines on the RadCartesianChart.
I'm using this xaml to display my data as individual lines & I can hide & add/remove items from the bound data "PlotInfos" and it is reflected on the chart:
<telerik:RadCartesianChart.SeriesProvider> <telerik:ChartSeriesProvider Source="{Binding FilteredSeriesInfos}"> <telerik:ChartSeriesProvider.SeriesDescriptors> <telerik:CategoricalSeriesDescriptor ItemsSourcePath="PlotInfos" CategoryPath="XCat" ValuePath="YVal"> <telerik:CategoricalSeriesDescriptor.Style> <Style TargetType="telerik:LineSeries"> <Setter Property="Stroke" Value="{Binding PenBrush}"/> </Style> </telerik:CategoricalSeriesDescriptor.Style> </telerik:CategoricalSeriesDescriptor> </telerik:ChartSeriesProvider.SeriesDescriptors> </telerik:ChartSeriesProvider></telerik:RadCartesianChart.SeriesProvider>
The charted data is selectable by the user. I can't find any example of TrackBall info being displayed for SeriesProvider charts using bound data. Does anyone have an example?

Thanks in advance, Steve
