Exporting items are inconsistent from RadGrid view in WPF Application

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

private List<ChildDto> GetAllChildrenInGrid(RadGridView grid)
{
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);
}
}

return children;
}

It will be great help if any one suggest on the same

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:d="http://schemas.microsoft.com/expression/blend/2008"

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

Content of RadPane no shown when setting IsHidden to false

Hi!

I have a case where setting the IsHidden property to "false" expands the hidden pane, but does not draw the content.
When I then toggle the IsHidden property to true and fals again, the content is displayed correctly!

What can be the cause of this?

Regards,
Lennart

Binding Document

I've seen a few examples - most Silverlight :-( - where you bind the RadRichTextBox to an "item"-object or data from a DataBase.
But how could this be done to a RadRichTextBox.Document.
Say I get a datarow from a table and I want to create a new document with content/text from this datarow.

GridView and Touch Scrolling

I am unable to get touch scrolling to work properly on my grid view. When I scroll using the mouse everything works perfectly, but if I use a finger the scroll always jumps to either the first or last record in the list.

Ideas/Suggestions?
