Can anyone suggest an elegant way to animate a cell (i.e. flash it) when the data in it changes. I'm using GridViewDataColumn and DataMemberBinding.

The only thing I've been able to come up with is to use the grid's RowLoaded to iterate through each cell in the row and pick out the DataContext and the binding's source to create a new event handler to run an animation. Unfortunately, RowLoaded isn't the best because it's called when re-sorting etc.

RadDataPager: Sorting with OData

Hallo,

I've bound an OData service via RadDataServiceDataSource to a RadGridView and a RadDataPager.

Unfortunately the sorting does not work across pages. I've traced trace the server side an found that the orderby property is not set on the query.

The connection is very simple:

<telerik:RadDataServiceDataSource x:Name="_partnerSource" AutoLoad="True" QueryName="AllPartners" />

<telerik:RadDataPager Name="_pager"

Source="{Binding DataView, ElementName=_partnerSource}" IsEnabled="True" PageSize="10"/>

<telerik:RadGridView Name="gridPartner" AutoGenerateColumns="False" DataLoadMode="Synchronous" IsFilteringAllowed="True" ItemsSource="{Binding DataView, ElementName=_partnerSource}">

The DataServiceQuery<PartnerInfo> AllPartners is take from the Service Reference

What may be missing or wrong?

Greetings Florian

How does Sampling Work?

I've read the documentation on sampling but it's still not clear to me exactly what RadChart is doing. For example I have a Scatter chart with approximately 3000 data points. The data points are spread, fairly evenly, across approximately 6 hours of time along the X axis. In other words, data is not disproportionately bunched anywhere along the X axis. It's pretty evenly spread out. The Y axis values range from approximately 60 to 66, with no particular pattern. Can you tell me exactly how RadChart would sample this data, assuming I select a sampling value of say 300 (1/10 of the data). I have not specified the method of sampling (average, min, max etc.), because I don't really know which would be best in my case.

Thank you.

How to use the same legend for multiple charts?

Hi telerik,

I wish to abuse the chart.
Since ChartLegend is a separate object referenced by the RadChart, I thought I could re-use the legend object to obtain a single legend for several RadCharts. This way I wanted to achieve the interactivity effects of hovering over graphs / legends and seeing the highlight in the other.

My starting point was four charts, where the first three were real plots (with hidden legend) where as the last was a RadChart with hidden ChartArea. That worked well, but with no interactivity.

If I create the ChartLegend object first and reference it from the remaining three RadCharts, I do get the legend headers in the ChartLegend, but still no interactivity.

Is this even possible? Or should I just 'accept' the separation and 'manually' handle the highlighting? Can you send me in a direction where I might get lucky?

Thanks,

Anders, Denmark

How export a Grid Hierarchy to Excel with to Telerik's controls for WPF?

Telerik RadControls for WPF Q1 2011 SP1

I have a grid hierarchy, I want to Export to Exel.
I used this code, but I don't have anything of the Grid Hierarchy in Excel

SaveFileDialog dialog = new SaveFileDialog();

dialog.DefaultExt = extension;

dialog.Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", "xls", "Excel");

dialog.FilterIndex = 1;

if (dialog.ShowDialog() == true)

{

using (Stream stream = dialog.OpenFile())

{

GridViewExportOptions exportOptions = new GridViewExportOptions();

exportOptions.Format = format;

exportOptions.ShowColumnFooters = true;

exportOptions.ShowColumnHeaders = true;

exportOptions.ShowGroupFooters = true;

RadGridView1.Export(stream, exportOptions);

}

I read foros where the controls don't support this Export to Excel.
Please, really I need your help.

Issue with IsDropDownOpen property

I have a radGridView, when the radGridView SelectionChanged event fires off, I need to set a combo to IsDropDownOpen = true;

The issue is that the IsDropDownOpen property is being set but the combo will not remain dropped down when the grid selection is changed using a mouse click.

The combo will remain dropped down when the grid selection is changed using the keyboard.

Either selection method calls the same method to set the IsDropDownOpen property.

I am using the 2011 - Q3 version of the wpf controls.

Any Ideas?

Activate un-pinned pane

My terminology is probably off here but what I need to do is to be able to make a pane that is currently minimized (not pinned and thus not visible except for the tab header) active (not pinned but it's contents now visible just as though I had moused over the tab). What I have is something kind of like the output tab of visual studio where I do a build and I want the output tab to be shown - currently I'm just calling PinAllPanes() in order to make sure the pane is shown but this isn't what I want (I don't want to pin the pane and I don't want to have to pin other panes in the group. I if the RadPane.IsActive setter were public I believe that would give me what I want, but, it's not.

Any help would be appreciated.
