Hi,
I am new to Radgridview and I am using MVVM pattern. I updated the Group Title for the grid in the following manner.

<telerik:RadGridView.GroupDescriptors>

<telerik:GroupDescriptor Member="GroupTitle" DisplayContent="GroupTitle" >

<telerik:GroupDescriptor.AggregateFunctions>

<telerik:CountFunction ResultFormatString="{} {0} matches found"/>

</telerik:GroupDescriptor.AggregateFunctions>

</telerik:GroupDescriptor>

</telerik:RadGridView.GroupDescriptors>

There will be a set of search results in a list and i added the group title in my viewmodel. when i debugged the code, I am getting proper group title name in my list. But sometimes the group header is not visible and sometimes it is visible. I want my grouptitle value to be visible whenever it is present in the list. Any workaround for this or any alternate way to achieve this?

Thanks,
Saranya,

Terrible Performance in Q3

I just downloaded the WPF Q3 trial, to determine whether RadMap might finally be hostable inside WinForms.

Good news.. RadMap Q3 finally has the capability.

Bad news.. Simply running in WPF, the demo app that ships with the solution .. Q3 is *much* slower than either Q1 or Q2 of the 2010 release.

This is a *huge* difference. It's gone from real-time response, to a lag of 5 seconds to zoom in/out.

I've tested this on 3 different machines (all Intel i5's with 4 to 8GB RAM and NVIDIA graphics cards (1x 9800, 1x 210, 1x 240 .. all of these are 2009 or later models).

In every single test, the new Q3 version is 400% or more slower than Q2. In addition, I noticed that the CPU of the machines will not reach more than 15% (approx) while in Q1, Q2 I would regularly see the CPU hit 40% when moving rapidly around the map.

Will this be fixed in Q4, or will there be a hotfix to address the problem?

Help with ScheduleView Appointment Source

I am very new to the Telerik controls in general. We have managed to write code using RadScheduler. But we like the new features in ScheduleView. But I am completely stuck on how the AppointmentSource works? I saw the example but couldn't understand how it works. Is there a more detail ( behind the code) example?

RadChart ignores PaletteBrushes when using StyleManager.Theme

Hi,

I want to use a custom color palette for my pie charts. But it never seemed to work until I finally figured out that one tiny setting on my RadChart was causing the trouble:

<telerik:RadChart UseDefaultLayout="False"

telerik:StyleManager.Theme="Windows7"

x:Name="radChart"

Grid.Row="1">

<DockPanel>

<telerik:ChartArea DockPanel.Dock="Left"

Width="150" Height="150"

LegendName="chartLegend"

x:Name="chartArea"/>

<telerik:ChartLegend x:Name="chartLegend"/>

</DockPanel>

</telerik:RadChart>

When I remove the theme from the XAML, everything works fine.

Did I miss something conc. themes and RadChart?

Thanks,
Thorsten

PS
I can post a working example, if required. Unfortunatly I can't upload it here.

Header in RadGridView

Hi,

I have couple of things about the RadGridView in particular. I have created a Radgidview in following way:-

<UserControl x:Class="MySampleClass"

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

mc:Ignorable="d"

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

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="Auto" />

</Grid.ColumnDefinitions>

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

</Grid.RowDefinitions>

<telerik:RadGridView Grid.Column="0" Grid.Row="0"

x:Name="MainGridView"

ItemsSource="{Binding Path=MetricsData}"

AutoGenerateColumns="False" CanUserDeleteRows="False" CanUserInsertRows="False" ShowGroupPanel="False" RowIndicatorVisibility="Visible" SelectionMode="Extended" SelectionUnit="Cell"

IsFilteringAllowed="False"

SelectedCellsChanged="MainGridView_SelectedCellsChanged">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="ColA" Name="Mkt" DataMemberBinding="{Binding Path=Market, Mode=OneWay}" IsResizable="False" IsSortable="False" IsReadOnly="True" />

<telerik:GridViewDataColumn Header="ColB" Name="SiD" DataMemberBinding="{Binding Path=Sub1, Mode=OneWay}" IsResizable="False" IsSortable="False" IsReadOnly="True" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

</UserControl>

This user control resides inside a ScrollViewer(which is inside a GroupBox) in the topmost Page.

The first thing is when I access column name using GridViewCellInfo.Column.UniqueName in code-behind, it returns the string from Binding Path, I was expecting the value from the header name. Is there any way to get the header value or name element.

Other thing, when the radgridview contains many elements and scrolled down, I want the header row to be fixed and only its contained elements to be scrolled. How can I achieve this.

When a mouse rollover occurs over some particular elements of RadgidView, I want to change the visibility of them as hyperlinks(some underline bar appears and color changes to blue) to show that these elements are clickable (I am handling Selected event). Is there any property over some column that I set.

Thanks,
Mark

Displaying Window Contents when dragging SplitContainer

Hi

When I resize panes using the RadSplitContainer, is it possible for the window contents to redraw as I move the bar around? At the moment, the display remains static, and only the bar moves. It seems to me in this day and age that the window contents should be rendered live as the bars are dragged around.

Thanks

PaneStateChanged

When one of my RadPanes is hiding/closing I want to check if something should have been saved.
I cannot find an event which could tell me that the RaPane is about to close/hide.

I see that one can use the RadDocking.PaneStateChanged.
But how can I find the RadPane's RadDocking?

SaveLayout with RadPaneGroupRegionAdapter

Hi,
I'm playing around with Miroslavs RadDocking example:
http://blogs.telerik.com/blogs/posts/09-08-31/using_the_raddocking_control_with_prism.aspx

When items are added to a RadPaneGroup by using Prism and the RadPaneGroupRegionAdapter they are not added as the base type RadPane. This is only a problem when I'm trying to serialize the Docking panels. SaveLayout() will produce this xml:

(Removed some attributes)

As you can see there's an element called Pane1 which should be a RadPane in order for the LoadLayout() to parse the xml without throwning an ArgumentOutOfRangeException.

What would be the best way to get this working?

Regards
Arnstein
