heya,

i am porting an existing project to telerik and since i changed my window to derive from RadRibbonWindow i experience flickerings when i resize the window (no code or eventhandler is handling the resizing). additionally i specified 

ResizeMode="CanResizeWithGrip"

 on the window.

most of the time the border and title-bar is flickering, sometimes the whole window.
on my tryout with another wpf component suite just the areas flicker sometimes, where i created "new space" through resizing.

is there a way to prevent this?

thx

EDIT: this is especially nasty, because the flickering area is black :(
EDIT2: after a sleep of my notebook most of the drawing-area of the program was now black. unfortunately i didnt do a screenshot. ..  :(

Dear all,

I am in a very bad situation , 

coz , I have started a wpf project ...all is well except in the case of radgrid view in wpf ...

I am expecting all the functionality of windows radgridview in wpf. like adding rows etc.

is there any way to add the windows rad control to wpf ?.

If anybody know a solution please share it with me............

Thanks and Regards,

Firoz

Hello,

I need help (again) with the RadGridview please.

PROBLEM :
I use a RadGridView to display some informations. And one column have a Binding with an Integer attribute.
When I edit a row, and put a value which is not a number in the cell, my application crash (normal).

I tried to use GridViewMaskedTextBoxColumn with MaskType="Numeric" but it doesn't work or I does not succeed in using it.

CODE :
I have a gridview with an ObservableCollection as ItemSource :

In my RoleUtilisateur class (implements IRoleUtilisateur) I have an Integer :

XAML :
(I deleted all columns except the one with the Binding with Integer attribute)

INFOS :
Visual Studio 2008
.NET Framework 3.5 SP1
Telerik 2010.1.603

How can I do to avoid crashing please ?

If you need more informations, please tell me.
Thank you in advance for your answer.

Regards,
G.B.

Hi,
I'm trying to implement a monitoring gridview that have a column of a time counter that increments in each second. 
For now the only solution that i came up with is to do a DispatcherTimer initiating foreach that increment each object and then rebind the grid, which of course is an awful performance hit.
Any suggestions?

Hi All,

Hello telerik,

I am going to use RadTileView Control in my appliaction with XML-DataBinding.
But I have some problems:

1.) I have tried out to manage to current State of the control in the code-behind file. Here in forum I found out that I have to use following call ->
RadTileViewItem radTileItem = settingRadTileView.ItemContainerGenerator.ContainerFromItem(buissinesObject) as RadTileViewItem;

I do get a reference to each RaTileViewItem in the collection but do not get a reference to the RadFluidContentControl, if I do this call
RadFluidContentControl fluidControl = item.Content as RadFluidContentControl.
While debugging I see at quickwatch that the content of the RadTileViewItem is a XmlElement.

What should I do to get / wrap an XMLElement to RadFluidContentControl  ?

2.)  Another issue is, when I am setting the MinimizedHeight / MinimizedWidth - Property of each RadTileViewItem in the code -behind file e.g in the SizeChanged-Handler, I have always to click at the TileView - Control in order to update the current view then after loading TileViewItems allocate whole space the is available. Only after a e.g Click on TileView RadTileViewItems change height and width setted in the code-behind file.

How can achieve a refresh on TileViewControl in the code-behind file whithout cklicking / user interaction ?

3.) I am setting the MinimizedHeight / MinimizedWidth - Property of each Item in the code-behind file in SizeChanged-Handler depending on the ActualHeight of the grid, but if I am setting my desktop resolution to 800x600 pixel some minimized items disappear and I have only 7. I read that at the moment there is no scrollerView for minimized Items, does it mean that at the moment I can just show a few items ?

4.) Can just header be visible in in minimized state without any content?

5.) And at least, how can I change the size of the content e.g of the large content dynamically ? If I change the resolution of the desktop some visible area of the large content disappear, although the snaptodevicepixel is checked an the size of the border in the LargeContent is setted to auto ? Have I to change the width and heigt ot the content control itself dinamically ?

Thank you.

Here is my code:

<Grid>

<telerikNavigation:RadTileView x:Name="settingRadTileView"

MinimizedItemsPosition="Left"

ItemsSource="{Binding Source={StaticResource ModulItems}, XPath=Modul}"

private void RadTileView_SizeChanged(object sender, System.Windows.RoutedEventArgs e)

{

Grid parent = this.settingRadTileView.Parent as Grid;

int itemsCount = settingRadTileView.Items.Count - 1;  // beacause one is alwasy maximized

foreach (var item in settingRadTileView.Items)

{

if (item != null)

{

// set the height of each item in order to show all items minimzed at the left.

Hello telerikTeam,

Thank you

I am trying to add a new item to the GridView. When the user tabs past the last column of the last row I'm inserting a new row and placing it in edit mode. I do this by handling the KeyDown event like this:

        private void RadGridView_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.Key == Key.Tab)
            {
                var grid = sender as RadGridView;
                var currentItem = grid.CurrentItem as OrderDetail;
                if ((currentItem != null) && (currentItem.IsValid))
                {
                    grid.BeginInsert();
                    grid.CurrentColumn = grid.Columns[0];
                }
                else
                {
                    e.Handled = true;
                }
            }
        }

I also handle the AddingNewDataItem event to add a new object:

        private void RadGridView_AddingNewDataItem(object sender, Telerik.Windows.Controls.GridView.GridViewAddingNewEventArgs e)
        {
            e.NewObject = OrderDetail.NewOrderDetail();
        }

The problem is that I need the new object to be added to the underlying collection that is bound to the ItemsSource property of the GridView so that a number of event handlers can be hooked up to events on the OrderDetail object. (These events bubble up list / property change notifications to the parent Order object for such things as calculating the Order total, sales tax, etc.).

The new row is being added and it gets set into edit mode but when I modify data in the columns for Quantity and UnitPrice no events are being published because the OrderDetail object is not inserted into the collection (which does the job of hooking up the events).

I tried to add the object to the collection but then I get two new rows added to the GridView. What I would like to do is add the OrderDetail to the underlying collection so that event handlers get hooked up but then set the row into edit mode on the first column. Is this possible or is there some other way to approach this?

Thanks,
Dave

Hello Telerik,

I'm trying to put an TileView in a BusyIndicator but the tileview doesn't appear.

Do you have a sample code to do this ?

Thank you.
