Does anyone know of an example of how to do smooth scrolling similiar to the Xceed grid with the RadGridView.

Basically what they do is allow you to sort filter and group without paging and just with the scroll bar. Say you have 1 million records you can scroll through them without hitting the database for all the data. It just gets the 200 at a time, you can set the value as well. All you need to do is give it a Iqueryable and it does the rest.

Can you do this with the RadGridView?

How to show a text over mappolygon at runtime

Hi,
My requirement is to show the text over the map polygon at runtime.
From the xaml we can do this like:

<telerik:MapPolygon Points="56,-100 56,-108 48,-108 48,-100" Fill="Green" Stroke="Red"

StrokeThickness="4" CaptionLocation="52,-104">

<telerik:MapPolygon.CaptionTemplate>

<DataTemplate>

<Grid Background="Yellow">

<telerik:MapLayer.HotSpot="0.50.5">

<TextBlock Text="My Custom Text" />

</Grid>

</DataTemplate>

</telerik:MapPolygon.CaptionTemplate>

</telerik:MapPolygon>

But from the code behind how we can do the same thing.

MapPolygon CreatePolygon(IEnumerable<Location> points, string areaName)

{

var polygon = new MapPolygon();

polygon.Points = this.pins.Points;

polygon.ToolTip = areaName;

// also I want to set the area name over the MapPolygon

return polygon;

}

Drag-n-drop usercontrol on map

Hi,

We are developing a new application. One of the feature that we are planning is a floor plan interface with ability to place controls on the map, and we are evaluating whether the RadMap is the right module to use.

The floor plan would be a single image, I figure this is possible by implement a custom ImageProvider
The zoom-out level needs to be limited to when the image fills the window
User need to be able to add new controls to the map, which can be a custom WPF user control, or a RadGauge. The control will be fixed at a map coordinate.
User needs to be able to drag-n-drop any control to any place on the map, and also rotate the control. The new placement and angle will be remembered.
User needs to be able to remove controls from the map (maybe through context menu on the control)

And hopefully 3-5 can be achieved through data-binding.

Is the RadMap module the right tool for what we needed? or is there some other control that would suite this scenario better?

ContextMenuOpening event lost in Pane Client

I have a client control in my RadPanes that uses the ContextMenuOpening event to create dynamic menus if the user right clicks on images in the control. If the RadPane has the Right click ContexMenu with the dockable options my control does not get ContexMenuOpening events anymore.

Solution for this is to set the ContextMenuTemplate to Null, but I would prefer to have the ContexMenuOpening event in my Control even if the RadPane has a ContextMenu. If my Control does not handle the ContextMenu event the RadPane could take it. May be this can be added to the wish list.

FilteringControl Prepare firing OnCollectionChanged?

I am overriding the FilteringControl to remove IsContainedIn and IsNotContainedIn. My code looks like this:

public class StringFilteringControl : FilteringControl

{

public override void Prepare(GridViewBoundColumnBase column)

{

base

.Prepare(column);   // <-- This fires OnCollectionChanged if actions are removed

var vm = this.DataContext as FilteringViewModel;

if (vm != null)

{

vm.AvailableActions.Remove(FilterOperator.IsContainedIn);

vm.AvailableActions.Remove(FilterOperator.IsNotContainedIn);

}

The base.Prepare call is firing a collection changed event if actions are removed, and this is causing an unwanted refresh of the grid every time the filter control is opened by the user. If I have a custom filter control, but do not remove actions, then the collection changed event is not fired, so the removal of actions seems to be the reason why the event is triggered.

I do not want the collection changed event to fire, or I need a way to know that the event was fired by the Prepare. Is there a way to prevent this event from firing?

Thanks for your help.

Hiding aggregate result in group header

Hi,

I am using aggregate function to calculate sum of a certain column in my grid. However, the sum value is displayed both on the footer as well as the group header. How can I hide the value for m showing on the group header?

Also, I am doing the grouping programmatically, is there a way to hide the column that is grouping member from the showing in the grid? Currently, the group column displays its value in the group header as well as in the grid itself. I think it is sufficient to have the data on the header only. How can I achieve that?

Regards

RadDocking looses state of contained controls such as RadGridView

I have an application that uses RadDocking to host a RadGridView control. When the application initially loads the grid's databinding, sorting, filtering, grouping, etc. work fine. However, if the pane containing the RadGridView control is pinned, unpinned, or floated all user customizations to the grid such as sorting and filtering are lost. It appears that the the grid is reinstantiated when the user performs any of these actions. I have set IsContentPreserved to True in the RadPaneGroup that hosts the RadGridView, but the grid's state is still not preserved. Is there a way to preserve state in this scenario?

<telerik:RadDocking HasDocumentHost="False" Grid.Row="2" PreviewUnpin="RadDocking_PreviewUnpin">

<telerik:RadSplitContainer InitialPosition="DockedBottom">

<telerik:RadPaneGroup IsContentPreserved="True">

<telerik:RadPane

Header="Grid"

CanFloat="False"

CanUserClose="False"

ContextMenuTemplate="{x:Null}">

<Grid>

<telerik:RadGridView AutoGenerateColumns="False" SelectionMode="Multiple" RowIndicatorVisibility="Collapsed" ItemsSource="{Binding}" IsReadOnly="True" SelectionUnit="Cell">

<telerik:RadGridView.Columns>

<telerik:GridViewSelectColumn Width="20"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=InventoryDate, Mode=OneWay}" Header="Inventory Date" DataFormatString="{}{0:MM/dd/yyyy}"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=BridgeNumber, Mode=OneWay}" Header="Bridge #"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=CreatedBy, Mode=OneWay}" Header="Created By"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=CreatedDate, Mode=OneWay}" Header="Created Date" DataFormatString="{}{0:MM/dd/yyyy}"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

</telerik:RadPane>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

</telerik:RadDocking>

Thanks for any suggestions.

Could not load file or assembly 'Telerik.Windows.Controls.Docking, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies.

I have tried the latest WPF4 build 01582RadControls_for_WPF40_2011_2_1010_TRIAL_hotfix.zip and RadControls_for_WPF40_2011_2_0920_Trial_hotfix.zip. I have verified that the assemblies are in the proper place. Had no problem with Telerik.Windows.Controls.RibbonView; however when I run my program I get the following exception when trying to render the MainWindow.

Could not load file or assembly 'Telerik.Windows.Controls.Docking, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies.

Anyone else having this problem?

Thanks in advance,
Steve

P.S. The Examples app doesn't run either.
