RibbonView with Implicit Theme Design Exceptions

I have vs2013 and Q1 2013 using the OfficeSliver Theme creating a project with 4.5 Framework. I am getting a design error anytime a try to open any XAML file in designer. I am getting this on brand new solutions with no controls on the window.
I tried what was listed on this form http://www.telerik.com/community/forums/wpf/ribbonview/ribbonview-w-windows-8-theme-rd---blend-with-sketchflow-for-vs-2012-preview-crashing.aspx and confirmed that my theme file was indeed set the way suggested and it was but that is not changing the fact that I can not load a completely blank window.

Any suggestions on what I can do?

This is the design error that I am getting:

System.ArgumentException

Speed up RadListBox

Hello.
I need to load large data as RadListBoxItems with template like.
My code:

<telerik:RadListBox Name="testlv">

<telerik:RadListBox.ItemTemplate>

<DataTemplate>

<Border BorderBrush="Turquoise" BorderThickness="0,1,0,1" Width="{Binding Path=ActualWidth, ElementName=grdzero}">

<WrapPanel Orientation="Vertical" >

<TextBlock Foreground="Black" Text="{Binding nazwa}" FontSize="16"></TextBlock>

<WrapPanel Orientation="Horizontal">

<TextBlock Foreground="Black" Text="Cena: " FontSize="16"></TextBlock>

<TextBlock Foreground="Black" Text="{Binding cena}" FontSize="16"></TextBlock>

</WrapPanel>

<WrapPanel Orientation="Horizontal">

<TextBlock Foreground="Black" Text="Kod: " FontSize="16"></TextBlock>

<TextBlock Foreground="Black" Text="{Binding kod}" FontSize="16"></TextBlock>

</WrapPanel>

</Border>

</DataTemplate>

</telerik:RadListBox.ItemTemplate>

</telerik:RadListBox>





And code behind:


private void getProducts(string query)
      {
          prodDG.Items.Clear();
          List<SearchProd> pL = FastSellSearchClass.lista.Where(x => x.nazwa.ToLower().Contains(query.ToLower()) || x.kod.Contains(query) && x.wID == int.Parse(Application.Current.Properties["warehouseID"].ToString())).ToList();
          testlv.ItemsSource = pL;

} 



List<searchProd> represent list of product. It work's like:

client press any key in keyboard, which open new window with radListBox, insert pressed key into textBox, and going into

getProducts(string query) to filter items (where query = pressed key).

So for example when somebody press 'S', it will search for items, where name or code contains 'S'.



Problem is that, with 3000 products page is loading for like 9-10 second.

When it's loaded, it tooks less than second to find any words with 'Sa' for example.

So is there any way to speed up opening window a little bit?

Smart mindmap like autolayout

Hi,

I am looking at implementing a automatic mindmap diagram layout in order to enforce the position of the items dropped as well as update the layout whenever a branch is expanded or collapsed. The basic behavior I am looking for is similar to the one provided as a sample with the mindmap layout sample. One of the tricky part is to update the existing item's position when the user expands a node in order to avoid items overlap. Do you recommand a particular approach in this area. XMind does a pretty good job in this area and this is the kind of behavior I am trying to implement.

WPF GridView Sorting issue

Hi,
We are creating columns dynamically. There are a few datetime columns where we set the datatype as DateTime and CellEditTemplate as below.

dataColumn.DataType = (typeof(DateTime?));
dataColumn.DataFormatString = "{0:dd-MMM-yyyy}";
dataColumn.TextAlignment = TextAlignment.Right;
dataColumn.CellEditTemplate = GetDatePickerTemplate(dataColumn);
}

private static DataTemplate GetDatePickerTemplate(GridViewDataColumn column)
{
var fef = new FrameworkElementFactory(typeof(FormatedRadDatePicker));
................

The issue is when you sort the grid with this datetime column and try to edit any value in this column the application crashes with below error:

Dispatcher UnHandled Exception: System.ArgumentException: Object must be of type DateTime.
at System.DateTime.CompareTo(Object value)
at Telerik.Windows.Data.FunctionComparer.Compare(Object x, Object y)
at Telerik.Windows.Data.ListExtensions.BinarySearch[T](IList`1 items, T value, Func`3 compareFunc)
at Telerik.Windows.Data.KeyedCollection.IndexOf(Object value)
at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.FlatLayoutStrategy.RefreshAlternation(GridViewDataControl parentGrid, GridViewRow gridViewRow, Object dataItem)
at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.FlatLayoutStrategy.RealizeRows(Int32 startIndex, Int32 endIndex, Double& verticalOffset, HashSet`1& realizedRows)
at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.FlatLayoutStrategy.MeasureOverride(Size availableSize)
at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.MeasureOverride(Size availableSize)
at System.Windows.FrameworkElement.MeasureCore(Size availableSize)...........

To me it looks like after the cell edit is over grid tries to put the newly edited data to its rightful place based on sortdescriptor. Probably it fetches the data from DateTimeTextProperty as string type and is not able to compare with DateTime values of other cells....

Secondary Y-Axis for Chart

Hello,
I can add secondary y-axis to my chart.Currently the chart has secondary Y-axis equals to the number of series aligned to that axis.
But our requirement is to have only one secondary Y axis should be configured to the all the series which have aligned to that secondary Y axis.In short, I would like to have only one secondary Y-axis to right for multiple series and it should configure scale automatically on that axis according to series values. Just like we have primary vertical Y on Left axis which scales automatically for any multiple number of series.
Is it possible to assign the same primary Vertical Y on Right axis for any number of series?
I have gone through the documentation of shared vertical axis here http://www.telerik.com/help/wpf/radchartview-axes-multipleaxes.html
but we have dynamic multiple series and we are adding series to the chart dynamically.So how do i set the secondary vertical axis?.Currently I have set it to for every series and that's why multiple vertical axes are getting added.

Could you please help me to resolve this issue if it is possible to implement.
Thank You in Advance

Avoid stretching of grid column when column's content width changes

Hello.

I have a problem with columns in grid. I would like to have columns with the same width and this width should not depend on the content of the columns.

Here is my code:

    <Grid Margin="5" >
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*" />
                <ColumnDefinition Width="*" />
                <ColumnDefinition Width="*" />
                <ColumnDefinition Width="*" />
            </Grid.ColumnDefinitions>

            <telerik:RadTreeView Margin="5,0,5,0" Grid.Column="0" 
                                 ItemsSource="{Binding TreeView0}" />
            <telerik:RadTreeView Margin="5,0,5,0" Grid.Column="1" 
                                 ItemsSource="{Binding TreeView1}" />
            <telerik:RadTreeView Margin="5,0,5,0" Grid.Column="2" 
                                 ItemsSource="{Binding TreeView2}" />
            <telerik:RadTreeView Margin="5,0,5,0" Grid.Column="3" 
                                 ItemsSource="{Binding TreeView3}" />
    </Grid>

When I am expanding tree in RadTreeView the column changes it's width and other columns changes respectively. But I would like to have four columns with width = 1/4 of grid's width. RadTreeView has its own ScrollBar for horizontal scrolling.

Is there any property on RadTreeView that stops it from growing horizontally? I tried to enable horizontal scrollbar but it didn't helped.
