Closing events for multiple floating RadWindows

Hi, I've made a modal dialog using RadWindow (W1), and had another RadWindow (W2) pop up from W1.
What I want to do is when I close W2, W1 should get notified of the closing event of W2, but currently as far as I know, this is impossible.
Please help me!

Hello all,

I am facing one problem, when i am sorting a data with project ID's and tried to export that data it gives inconsistent records on excel sheet.
it will fetch till page no 4 and after that it will skip the reocrds form page no 5. and next it will take records form page 6..

Code sample

{
List<ChildDto> children = new List<ChildDto>();

for (int i = 0; i < gvPagerBottom.PageCount; i++)
{
gvPagerBottom.PageIndex = i;

foreach (var item in grid.Items) : it gives item count 0 here
{
children.Add(item as ChildDto);
}
}

Layout computation of shapes inside Container

Hello my question is simple, I would like to take advantage of your rich Layout computation feature to set the position of items inside a Container, is it possible?

After some attempts and a search on the web I couldn't find out. If it's not possible out of the box, is my only solution to nest a diagram inside the container ? (is it possible concretely?)

My need here is to have nested Shape nodes, with a Layout computation for each node.

Thanks

How to make scrollbar appear in RadPaneGroup

Hi,

I am having trouble with the RadPaneGroup. When the panegroup is filled with panes no scroll buttons appear(see image).

I have given each pane a very long name so they fill everything, see my XAML below:

<telerik:RadDocking.DocumentHost>

<telerik:RadSplitContainer >

<telerik:RadPaneGroup Name="hostPaneGroup" OverflowMode="Scroll">

<telerik:RadPane Name="instrumentsPane" Title="Settingsssssssssssssssfdddddddddddddddddddddddddddddds" telerik:RadDocking.SerializationTag="instrumentsPane" CanUserClose="False" ContextMenuTemplate="{x:Null}"/>

<telerik:RadPane Name="calibrationPane" Title="Calibrationddddddddddddddddddddd" telerik:RadDocking.SerializationTag="calibrationPane" CanUserClose="False" ContextMenuTemplate="{x:Null}"/>

<telerik:RadPane Name="commentsPane" Title="Commentffffffffffffffffffffffffffffffff" telerik:RadDocking.SerializationTag="commentsPane" CanUserClose="False" ContextMenuTemplate="{x:Null}"/>

<telerik:RadPane Name="ratesWithinPane" Title="Rates Withinffgggggggggggggggggggggggggggggg" telerik:RadDocking.SerializationTag="ratesWithinPane" CanUserClose="False" ContextMenuTemplate="{x:Null}"/>

<telerik:RadPane Name="ratesWithinBetween" Title="Rates Betweenhhhhhhhhhhhhhhhhhhhhhhhhhhh" telerik:RadDocking.SerializationTag="ratesBetweenPane" CanUserClose="False" ContextMenuTemplate="{x:Null}"/>

<telerik:RadPane Name="ratesVSConcentration" Title="Rates VS Concentrationjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj" telerik:RadDocking.SerializationTag="rateVSConcentrationPane" CanUserClose="False" ContextMenuTemplate="{x:Null}"/>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

</telerik:RadDocking.DocumentHost>

I have set the OverflowMode="Scroll" and i have also tried different scroll modes using the property ScrollMode(Item, Pixel, ViewPort).

I dont understand why the scrolling functionality doesnt show. Have i done something wrong or am i missing something? :)

Best Regards,
Jeppe

Parse xls / xlsx without RadSpreadsheet

Is there a way to parse an xls/xlsx file using Telerik.Windows.Documents.Spreadsheet in a class library without any reference to a wpf item?
I'm currently using OLEDB to convert excel to csv, but your RadSpreadsheet works better!

DragDrop between Treeview & GridView

Hello,
I need to D&D from GridView to TreeView (+ Treeview on itself).
Everything is OK, based on the examples that are in the WPF Demo (TreeViewDragDropBehavior & GridViewDragDropBehavior).
The problem is I'm not able to reproduce the standard behavior like the one in Windows explorer :
- If the node is not expanded, I need to expand it after a delay. I tried the DropExpandDelay, but without any success
- There's no effect to show I'm over a node ("over" effect).
Any advices will be welcome
Best regards

MVVM Grid Binding how to handle Parameters

Hello I've a RadGridView that is placed withing a RadWindow and wrapped within an UserControl.

The RadWindow will be initialized by an ContextMenu of a parent RadGridView (selected item) please see the code snippets below.

Code from the ContextMenu to open a new RadWindow:

var tmpItem = row.Item as ItemModel;

.....

case "ViewRelatedItems":

if ( tmpItem != null )

{

RadWindow radWindow = new RadWindow();

radWindow.Width = 510;

radWindow.Height = 350;

UserControlRelatedItemsEntries ucTmp = new UserControlRelatedItemsEntries(tmpItem.ID, tmpItem.Type);

radWindow.Content = ucTmp;

radWindow.Owner = Application.Current.MainWindow;

radWindow.WindowStartupLocation = WindowStartupLocation.CenterScreen;

radWindow.ResizeMode = ResizeMode.NoResize;

radWindow.Header = "Entries:"; //TODO

radWindow.Show();

}

break;

XAML of the UserControl:

<UserControl x:Class="TEST..UserControlViewEntries"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:sys="clr-namespace:System;assembly=mscorlib"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

xmlns:viewModel="clr-namespace:test.ViewModels;assembly=Test.ViewModels"

mc:Ignorable="d"

d:DesignHeight="300" d:DesignWidth="500">

<UserControl.DataContext>

<viewModel:MyViewModel />

</UserControl.DataContext>

<Grid>

<telerik:RadGridView x:Name="radGridEntries" Margin="0,30,0,0"

ItemsSource="{Binding Entries}"

AutoGenerateColumns="False" DataLoadMode="Asynchronous">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding UserName}" Header="User"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Date}" Header="Date"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding XDoneAsString}" Header="XDone"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Description}" Header="Description"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Type}" Header="Type"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

</UserControl>

Code of the ViewModel

public class MyViewModel : ObservableObjectBase

{

#region Properties

public int SelectedItemID { get; set; }

public int SelectedItemTypeID { get; set; }

private ObservableCollection<XModel> _items;

public ObservableCollection<XModel> Entries

{

get

{

if ( _items == null )

{

_items = new ObservableCollection<XModel>();

var tmpResults = DataService.GetItems( this.SelectedItemID, this.SelectedItemTypeID);

tmpResults.ForEach( i => _items.Add( i ) );

}

return _items;

}

#endregion

#region Methods

#endregion

#region Constructors

public MyViewModel ()

{ }

#endregion

}

I come here not further...

How can i put the two required values SelectedItemID and SelectedItemTypeID to the ViewModel, so that they can be used when the DataBinding request the the Entries?

I'll hold this 2 values inside the ContextMenu "tmpItem" (e.g. tmpItem.ID and tmpItem.Type) but i've no idea how i could put that throuth the UserControl and ViewModel.

I think I am using the wrong approach... hopefully someone could give me an idea how to solve this issue.

Any help on this would be very welcome!

Kind regards
Daniel
