Aggregate functions between rows or columns

In some gridviews I need to be able to show variance between rows and/or columns as percentage or delta change.

Is there anything in Telerik controls that support anything like this. My one solution is just to calculate it outside and add new items to the collection that represent these aggregate values. Are there any simpler or better solutions available?

Editing grouped data => inconsistent row-order

Hi,

when editing grouped data the row-order changes when the gridview is not sorted at all or the sort-values are not distinct.
After editing a value the just edited row jumps to the last position of the group. Maybe it has something to do with the RowState (the gridview is bound to a strongly typed DataSet). Also the aggregates are not updating when the data changes.
Also after programmatically grouping a few times the GridViewDataColumn's SourceUpdated-events are not getting raised anymore? Is grouped-data supposed to be read-only?
Am I missing something?

Any ideas?

Best Regards
Steffen

RadPieChart series overlapping problem

Hi,
I have problem with my RadPieChart. I have added pie chart successfully but when I tries to add more series of Pie, they gets overlapped.
That's why i am not able to see my previous pie series properly.Also the labels are getting overlapped. Is there any way to avoid this problem?
I have one more question about bubble series. Is there any way to add bubble series in the RadChartView charts or any way to implement this ?
Thanks in advance.

Need to show the count of appointments

Hi,

I'm trying to show the count of appointments that are there in total and that have been filtered.

I'm trying to achieve something like - You're viewing "x" out of "y" appointments.
where,
x = count of the filtered appointments
y = count of the total appointments.

I've found on some forum posts that this is not achieveable (2011 posts) but those posted later (2012-2013) show some tricks to acheive this. I wasn't able to acheive this. Could you please help me with the same?

OpenAccess with DataForm

I'm new to Open Access, WPF and XAML.
My problem is I'm using an OpenAccess reverse-modelled table as the source for a WPF DataForm.
Everything works great as long as I 'Edit' rows but...
- can't Add (button is disabled)
- can't Delete (button is disabled)
- can't Cancel an edit (button is disable)
Committing an Edit works great. Navigation works Great.

Am I missing a setting in my Model, WPF or in XAML?

Thanks...

Is there a Command for the RadTileList

Hi,

i would like to use the RadTileList for the selection of single files from a Recently Used File list. How can I attach a command which gets executed when the users selects a tile?

I know that in the way Modern UI works there should be a separate action list with all the available actions. I just want that a single action is executed.

Right now I am using a separate button which is not intuitive especially within a touch based UI.

Regards,
Peter

Override default cell context menu with autogenerated columns

I've searched for a while but cannot seem to find a clear answer that works for the issue. I have a datagrid that is entirely auto generated. To this I added a context menu for right clicks when the cell is not in editable mode (see below). I would like to use the same menu when the cell is in edit mode i.e. I want to override the default context menu. I've tried various options including adding a CellEditTemplate in the code behind but this does not work because I need to reference the instance of the context menu in a non static (not sealed) context and templates only appear to want to work in a static/sealed context. What should I be doing?

<telerik:RadGridView x:Name="dataGridView" Margin="5,10,5,5"

AutoGenerateColumns="True"

AutoGeneratingColumn="DataGridView_AutoGeneratingColumn"

...other options....>

<telerik:RadGridView.ContextMenu>

<ContextMenu x:Name="gridContextMenu">

<MenuItem x:Name="clearCellMenuItem" Header="Clear Cell" />

<MenuItem x:Name="clearRowMenuItem" Header="Clear Row" />

<MenuItem x:Name="clearAllMenuItem" Header="Clear All" />

<Separator x:Name="separatorMenuItem" />

<MenuItem x:Name="copyMenuItem" Command="Copy" Header="_Copy" />

<MenuItem x:Name="pasteMenuItem" Command="Paste" Header="_Paste" />

</ContextMenu>

</telerik:RadGridView.ContextMenu>

</telerik:RadGridView>

Thanks

How to set DataTemplate of HierarchyChildTemplate (Code)

Hello,

I was trying to build up the DataTemplate for the HierarchyChildTemplate in my code.

As example the one from the online documentation http://www.telerik.com/help/wpf/gridview-how-to-access-child-gridview.html

</telerik:RadGridView.ChildTableDefinitions>

<telerik:RadGridView.HierarchyChildTemplate>

<DataTemplate>

<telerik:RadGridView ItemsSource="{Binding Children}" Name="childGrid" ShowGroupPanel="False" />

</DataTemplate>

</telerik:RadGridView.HierarchyChildTemplate>

</telerik:RadGridView>

I tried something like:

gridView.HierarchyChildTemplate =
