Support for filtering with a VirtualizedStackPanel (or workaround)

Hello,

I have a very common problem that I have seen referred to multiple times in this forum.

My RadComboBox (Q1 2011) has several thousand items in it, and opening the dropdown is very sluggish and sometimes unusable. Using the VirtualizedStackPanel allows the dropdown to run blazing-fast, but of course I lose the ability to filter (as documented and mentioned in other forum posts).

The problem is that it is absolutely crucial that I'm able to perform filtering and have the speed provided by the VirtualizedStackPanel. All forum replies are unclear as to whether you plan on supporting this in the future. In the meantime, I was hoping that you could point me to a reasonable solution.

I did find a solution deep in your documentation that went so far as to use some kind of Google search provider, but the implementation was very involved.

Is there a simple way to mimick filtering behavior with a VirtualizedStackPanel? I'm open to just about anything at this point.

Thanks for your time,
Jon

DataBinding example using WPF and customer business objects

I have a GridView that displays the data fine when in "AutoGenerateColumns" mode. Otherwise no data is present. The grid is databound to a List<> of business objects.

Here is the Markup

<telerik:RadGridView Grid.Row="1" HorizontalAlignment="Left" Margin="8,8,0,0"

x:Name="grdCustomerList" VerticalAlignment="Top" Width="Auto"

Height="159" AutoGenerateColumns="False" IsReadOnly="True" RowHeight="28">

<telerik:RadGridView.Columns>

<telerik:GridViewColumn Header="Tenant DBA" DataContext="{Binding TenantDBA}" Width="180" />

<telerik:GridViewColumn Header="Type" Width="120" DataContext="{Binding TenantContextType}" />

<telerik:GridViewColumn Header="Region" Width="120" DataContext="{Binding Region}" />

<telerik:GridViewColumn Header="Status" Width="120" DataContext="{Binding Status}" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

Here is the #CS

List<TenantCardView> tenantsConverted = TenantConverter.ConvertTenants(tenants);

grdCustomerList.ItemsSource = tenantsConverted;

Thanks,

Reid

(P.S) when you paste in formatted code you cannot bring the cursor back to the top to edit text outside the formatted code block.. I had to do this message over 3 times. The trick is to layout all your text first, then drop in the code blocks. :)

Is it possible to sort on GridViewSelectColumn?

I would like to sort my RadGridView on the GridViewSelectColumn, moving the selected rows to the top if possible. Do you have any demos to show how this is done?

Change value text for particular integer

Hello,

I'd like to use numericupdown from 0 to maxvalue. But is it possible to display "auto" instead of "0".

Because i need to refer to "0" as a special number...

Have you an idea ?

Otherwise i will use a combobox...

Thanks

Gauges takes too long to render

We have an application where we are rendering about 30 gauges in the tab control (about 10 gauges per tab) and we have a significant delay when switching between the tabs. I have created a sample application to illustrate the issue.

Note that the last page, contains a bunch of rectangles (400) with gradients, opacity, shadow/blur effects applied to them, but still they are rendered nearly twice as fast compared to the Telerik gauges.

P.S. How can attach a sample project in the forum?

Problem in "adjusting" appointment's times

Hi Telerik,

I'm experiencing a strange behavior of the ScheduleView. I set schedule to view by day and had one hour increment as shown below. The ScheduleView had SnapAppointments="True". The problem is I couldn't adjust down to one hour slot, but I could change it through appointment edit dialog. For example, I couldn't slide end time from 3AM to 2AM where start time is 1AM. Any ideas what went wrong? Thanks.
