Hi everyone,
we use a collection with dynamic objects which is binded to a RadGridView.
All colums and rows are shown correctly but unfortunatly the integrated search function (ctrl + f) does not search within attributes which are added dyanmically to the objects.
It works only for attributes which are directly implemented.

Is it a common behaviour of the search function or may be a bug \ missing feature?

Thank you for your help!

[Solved] Binding to DeleteButton Visibility

Hi my appointments have a active flag and when it's false, I would like the delete button to hide. I was reading that I should edit the schedule view xaml code but my bindings aren't correct. Any ideas?

<telerik:RadButton x:Name="DeleteButton"

Style="{StaticResource DeleteButtonStyle}"

Command="{x:Static local:RadScheduleViewCommands.DeleteAppointment}"

ClickMode="Press"

CommandParameter="{Binding RelativeSource={RelativeSource TemplatedParent}}"

Visibility="{Binding Active, Converter={StaticResource BooleanToVisibilityConverter}}"

IsTabStop="False" />

Calculator Picker and decimal places

Is there a way to get the calculator picker to display 1.00 instead of just 1? I want to use it to display money values and 1.00 feels better than just 1.

Error AsyncSqlGeospatialDataReader

Hi,

I have successfully used the AsyncSqlGeospatialDataReader to read shape data stored in a geometry column in SQL. I first read the geometry objects into a local collection and then assign that collection to the reader

var readerRail = new Telerik.Windows.Controls.Map.SqlGeospatialDataReader();

readerRail.Source = RailShapes;

readerRail.ToolTipFormat = "{SegmentLabel}";

readerRail.GeospatialPropertyName = "ShapeWKT";

readerRail.PreviewReadCompleted += readerRail_PreviewReadCompleted;

However, while this has worked on three previous collections on this specific one I get a "Non-static method requires a target" error. It seems as if some of the shape data must then be an issue but I have no idea where to start looking.

PS: SQL Management studio can query the data and display it

Droping files to a RadDocking/DocumentHost

Hi, I have a wpf application which main area is RadDocking control with DocumentHost and so on. Actually it is Tab MDI application based on RadDocking. I would like to drag and drop files to this area of the application from windows explorer. For RadDocking I can handle PreviewDrop event, but Drop event is not raised. Feedback event is not raised to (for custom visual cursor). I tried to work with DragDropManager but got same behavior. Allow drop is set true for RadDocking control and qindow as well. Solutions?

Thanks,

Vladimir

Docking not culling manually created SplitContainers & RadPaneGroups

When a user wants a control added to their layout, we want it to pop up front and center.

So we do something on the order of:

void MakeNewPane(RadPane newPane)

{

RadPaneGroup radPaneGroup = new RadPaneGroup();

RadSplitContainer splitContainer = new RadSplitContainer();

// Fixed 300x400 size, centered on the main window, so it's easy to find.

Window parentWindow = Window.GetWindow(this);

splitContainer.SetValue(RadDocking.FloatingSizeProperty, new Size(400, 300));

splitContainer.SetValue(RadDocking.FloatingLocationProperty, new Point((parentWindow.ActualWidth - 400) / 2, (parentWindow.ActualHeight - 300) / 2));

splitContainer.Items.Add(radPaneGroup);

radDocking.Items.Add(splitContainer);

radPaneGroup.AddItem(newPane, DockPosition.Center)

pane.MakeFloatingDockable();

}

That works well enough.. And from the user's point of view, they can drag/drop/stick the pane wherever they want.. all good so far.

When we go to save the layout though, it looks something like this:

<RadDocking>

<SplitContainers>

<RadSplitContainer Dock="DockedLeft" Width="414" RelativeWidth="100" RelativeHeight="100" IsAutoGenerated="True">

<Items>

<RadPaneGroup RelativeWidth="100" RelativeHeight="100" IsAutoGenerated="True" SelectedIndex="0">

<Items>

<RadPane SerializationTag="PortfolioHierarchy1" IsDockable="True" Title="Hierarchy" Header="Hierarchy" CanDockInDocumentHost="False" />

</Items>

</RadPaneGroup>

</Items>

</RadSplitContainer>

<RadSplitContainer Dock="DockedTop" RelativeWidth="100" RelativeHeight="100" IsAutoGenerated="True">

<Items>

<RadPaneGroup RelativeWidth="100" RelativeHeight="100" IsAutoGenerated="True" SelectedIndex="0">

<Items>

<RadPane SerializationTag="PortfolioSummary1" IsDockable="True" Title="Summary" Header="Summary" CanDockInDocumentHost="False" />

</Items>

</RadPaneGroup>

</Items>

</RadSplitContainer>

<RadSplitContainer Dock="DockedLeft" Width="240">

<Items>

<RadPaneGroup SelectedIndex="-1">

<Items />

</RadPaneGroup>

</Items>

</RadSplitContainer>

<RadSplitContainer Dock="DockedLeft" Width="240">

<Items>

<RadPaneGroup SelectedIndex="-1">

<Items />

</RadPaneGroup>

</Items>

</RadSplitContainer>

<RadSplitContainer Dock="DockedLeft" Width="240">

<Items>

<RadPaneGroup SelectedIndex="-1">

<Items />

</RadPaneGroup>

</Items>

</RadSplitContainer>

</SplitContainers>

</RadDocking>

Note the extra RadSplitContainers and RadPaneGroups that are empty..

Looking through the code, there seems to be an internal property that I can't get to ( IsAutoGenerated=

"True")

that would allow the RadDocking to clean things up when refreshing.. basically delete the empty ones.

How can I do that through code? I can't figure out if there's an event I should use to clean things up or if I can somehow use AutoGenerated groups/containers myself.

I'd much rather just say: radDocking.AddPane(newPane, CenterParent, 300x300), and let everything else be auto from there.

Raddocking bug or strange behavior related to RadPropertyGrid

Hello,

I'm currently using the free trial TelerikDevCraftUltimateSetup_2016_4_1317_1 have found some strange behavior or a bug whilst trying to recreate an existing layout I want to replicate.

I have some RadPane's which needs to be docked as unpinned so they slide in and out when clicked. Inside the PadPane is a RadTabControl with 3 tabs.If I then put a PropertyGrid inside a RadTabItem the RadPane no longer stays open when a tab item is clicked. Is this a bug? Is there a way to stop this happening?

I've attached an example showing the problem

On the attached,

1. Click Header2 to unhide the pane (keep unpinned)

2. If you click between the 2 tabs with headers "Works Okay" you can see the expected behavior where the panel does not slide away

3. If you click on the tab with header "Not Working" and then then another tab the panel slides out of view. This tab contains a RadPropertyGrid. How can this be prevented?
