Print all the columns in the same page when we do Print Preview.

Hello Team,

Here we have a Telerik gridview and around 25 no. of columns is there. The problem is when we view Print Preview the output appears but not exactly what we expected. The 1st page take few columns and the rest goes to 2nd page and rest one goes to 3rd page but if we have 4 rows in a grid along with 25 columns, then the result must appear on the same page after the first best fit columns on the same page.

Please see below the logic of Print Preview-



public

static void PrintPreview(GridViewDataControl source, bool modal)

{

var window = new Window { Title = "Print Preview" };

var dialog = new PrintDialog();

var document = source.ToPrintFriendly().ToFixedDocument(dialog);

var documentViewer = new DocumentViewer

{

Document = document

};

window.Content = documentViewer;

if (modal)

window.ShowDialog();

else

window.Show();

}

I have tried the given link in the forum and customise the logic but no luck to achieved what we expected as a output-
Here's link- http://www.telerik.com/community/code-library/wpf/gridview/radgridview-print-and-print-preview.aspx

Kindly help me out to over come this issue.

Regards,
Naren

Checking/unchecking a tree node doesn't check/uncheck its child nodes automatically?

Hi,
I am using a treeview in tri state mode. Initially the treeview is is collapsed mode. When I click and check on a collapsed parent node, its child nodes never gets checked automatically.
Once the parent node is expanded (and even if its collapsed then) and I check this node, its children are checked properly.

My requirement is to have all the nodes initially collapsed to parent level, when I check/uncheck a parent node, the node should expand and its children should get checked automatically.

Here is my markup for the treeview

<telerikNavigation:RadTreeView Grid.Column="0" Grid.Row="0" x:Name="rdTreeView" ItemsOptionListType="CheckList" DockPanel.Dock="Bottom"

IsOptionElementsEnabled="True" IsRootLinesEnabled="True" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"

IsTriStateMode="True" Telerik:StyleManager.Theme="Office_Blue"

IsLineEnabled="True" IsEditable="True" Background="White" Margin="0,0,0,0" SelectionMode="Single"

IsExpandOnSingleClickEnabled="True" IsExpandOnDblClickEnabled="False"

BringIntoViewMode="HeaderAndItems" ItemContainerStyle="{StaticResource ItemContainerStyle}"

IsLoadOnDemandEnabled="False" IsVirtualizing="True" telerikTreeView:TreeViewPanel.VirtualizationMode="Hierarchical"

Checked="rdTreeView_Checked" Unchecked="rdTreeView_Unchecked">

</telerikNavigation:RadTreeView>

Is there something I am missing? Please help.

Thanks

IsSynchronizedWithCurrentItem not supported by the TileView?

Hi,
I am having trouble getting the TileView to synchronize its maximized item with the current item from the ItemSource. I eventually got this to work by handling the appropriate event handlers but I'm wondering if there's something that I am doing wrong because it would certainly be much cleaner if I didn't have to do this. Here is how my control is defined:

<telerik:RadTileView

x:Name="PART_TileView"

ContentTemplate="{StaticResource ImageTileViewContentTemplate}"

ItemsSource="{Binding Source={x:Static localdata:Image.ImageCollectionView}}"

IsItemDraggingEnabled="False"

IsSynchronizedWithCurrentItem="True"

IsTextSearchEnabled="True"

IsVirtualizing="True"

ItemTemplate="{StaticResource ImageTileViewItemTemplate}"

MinimizedColumnWidth="140"

MinimizedItemsPosition="Right"

MinimizedRowHeight="140"

MaximizeMode="ZeroOrOne"

TileStateChangeTrigger="SingleClick"

TileStateChanged="RadTileView_TileStateChanged"

>

</telerik:RadTileView>

Thank you in advance for your excellent support.
Pete

PS: I ran into a similar problem using the GridView when I bound 'ItemSource' to a collection. For that control I got the 'IsSynchronizedWithCurrentItem' behavior (thanks to your help) by binding to a collection view but that same trick isn't working for the TileView.

Problem with validation notifications

I have a tab control that has several tabs. each tab has a user control. All of the user controls are bound to an EF entity via viewModel binding. I've implemented some custom validation to my EF entity using IDataErrorInfo.

The main control is databound to master viewModel. Each child user control (which represents the contents of a tab) has its datacontext set to a property on the master viewModel (these properties are child viewmodels). These child VM are being instantiated once the master gets the entity from EF.

When I create a new tab control (for an entity), when it initially displays on the screen all my controls that are validation aware show the red outline I've defined for all properties that are required. But if I switch to a different tab then come back, the outlines are gone even though the value still doesn't pass validation. How do I fix this?

Is it in the way I have my UI designed? I can change it if needed, just not sure how.

Using the ExportTelerikGridDataUserControl with non-US culture

I have a WPF RadGridView with an associated ExportTelerikGridDataUserControl.
Using da-DK culture the XML export shows up in Excell with no decimals on numbers. I can solve this problem by using en-US culture but that has other implications that I cannot accept.
What can I do ?
