I'm trying to get the RadGridView for WPF to work in our software, and I was wondering if it is possible to show the Item count of a group in the group header without using predefined GroupDescriptions and preferably a XAML-only solution.

So far, all the examples on AggregateFunctions I have found, either have predefined GroupDescriptions in XAML or set the AggregateFunction programmatically using a hardcoded GroupDescription.

Edit:

I managed to fake the desired functionality by using the GroupDescriptions.CollectionChanged event:

 

private void GroupDescriptions_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e)

{

if (recordings.GroupDescriptions.Count > 0)

{

foreach (RadGroupDescription rgd in recordings.GroupDescriptions)

{

CountFunction cf = new CountFunction(rgd.PropertyName, rgd.PropertyName, "");

rgd.AggregateFunctions.Add(cf);

}

}

}

Strangely, the e.Action is never Add when dragging a column to the GroupPanel, so I had to do it this way.

 

 

Upgraded to 2009.2.701.35 and now it does not use the value in the HeaderText field.

This displays "Data.FirstName" as the column header instead of "First Name"


This displays "Default" as the column header instead of "Default Value"

Hi, i have a problem with a GridView, Is possible add events to gridView's childs? or how do I access to Childs?, I need the event Mouse_DoubleClick for the child

Hi,

I have a Button named photo and label named Signature on the form. and one submit button. When user clicks photo button or click on the label, some operation take place. When user clicks submit, operations related to Photo button and signatures label submits to the database. But if the user doesn't click photo Button or label, no DB is updated.

I want to know is there any way , I can force user to click the button or label . These are WPF controls.

Thanks,

Veena

I'm trying to change the date format of the RadDatePicker to display only "dd/MM".  I followed the example here but it doesn't seem to work - I've put the code in the Loaded event if that's any help.

Also, if there's any way to declare this in XAML it'd be a much neater solution.

Hi.

I do not know WPF (yet) and I haven't tried the controls, but from the demos it seems that the customization options for the controls is largely about color, linestyle and gradients.

I am looking for a WPF set which gives options to customize all visuals. Some customers may want click-handling on the chart legends, some want visuals like engineering units on top of the graph, some like it under, some would like it as tooltip. Some would like the various curves to be possible to enable/disable. Some would like to highlight a set of curves. Some would like other metadata to be drawn onto the graph backdrop. Some present a jpg from mspaint and state that they want it "exactly like that".

How customizeable are the WPF radcontrols from Telerik? Are their visuals fully expressed in XAML that I can edit so that I for example easily can remove/add a stackpanel with dimmed curve legends within the graph? 

That kind of stuff.

The screen real estate is very important, so it is important that, if I choose to not use the axis, title, legends, border etc, that they collapses and do not take up space. ie, That it can be stripped down to operate pretty much "fullscreen" within another wpf control container.

i am developping a project and i used rad scheduler control from release Q3 sp1 and now i need to use Rad masked text box which is contained in the new release (2009)  
i customized the scheduler and i want it to work using the old version, so can i use both versions  ,each for the control i wish or no ??
and if possible how can i do it ??

Hi

I've done quite a lot of WinForm stuff but I'm juist getting into WPF.

I have been experimenting with the simple thermometer demonstration on your website at:
http://www.telerik.com/help/wpf/linear-gauge-create-thermometer.html

And I'm getting the following error:

"The type reference cannot find a public type named 'MajorTickProperties'."

on:

<Style x:Key="ScaleMajorTick" TargetType="{x:Type telerik:MajorTickProperties}">
                                          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I'm guessing it's a reference/namespace issue but I'm referencing Telerik.Windows.Controls and Telerik.Windows.Controls.Gauge.

And I'm including xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" in the Window declaration.

<Window x:Class="Thermometer.MainWindow"

Hi,

If I have a grid like this:

  the column headers don't show the text in HeaderText, but the UniqueName or DataMemberPath text.

I have a telerik RadGridView that I would like to bind the row selection to a ICommand object, so my viewModel can execute it's code. I obviously cannot bind the SelectionChanged Event to a command, so I was wondering if there was another way to do this currently? Thank you for any assistance.
