Hi everybody,

I'm struggling for hours using the aggregate functions in my datagrid.
I'm using Telerik RadControls WPF Q2 2012 SP1.

Here is the code:

Xaml:


My collection is a set of objects defined as this:


and the VomRoomStayBreakDown contains this:



Which itself contains this:



Amount is composed of a decimal (Value) and a currency (Currency).

I am trying to Sum the decimal values from my VomAmounts (correctly displayed in the columns), but it always lead to the exception. 
"No generic method 'Sum' on type 'System.Linq.Enumerable' is compatible with the supplied type arguments and arguments. No type arguments should be provided if the method is non-generic."

Can somebody tells me what I am doing wrong over there ?

Thanks a lot !

Can the transition control be used in an MDI type scenario?

We have an application with multiple views, but each of them should only be showed inside the main view.

Is this advisable or is it a bad idea?

Thanks,
Jacques

Hello,

First I would like to say that I'm very impressed with level of customization you allow and the easy to understand and quite comprehensive online documentation.

I don't know whether to post this question under 'Chart' or 'ChartView' yet I attend to use the one that will resolve my current issue.

Platform
I'm developing for a touch environment (wpf pixelsense sdk 2).  

My goal
When a user touches anywhere on a graph (stacked area series) - show him information about the data point he touched.

In a technical aspect:
1. Use touch down/click/manipulation events to recieve a data point 
2. Alternative solution - to be able to get the item (data point) in a given position. This way I will be able to trap touch events manually.

Limitations
I cannot use any mouse events, only touch events.

What I've tried:

experiment  1
1. Add 'ChartTrackBallBehavior' to my chart
2. Register to 'TrackInfoUpdated' event
3. Use 'e.Context.ClosestDataPoint' to get data point of current position

Result
Since I'm using touch device I need this event to be triggered when touching (touchdown event) but it doesn't. 
I saw a possible workaround but it seems to be relevant only to wp8 controls and not to wpf (link)

experiment 2
1. Register to 'radChart.DefaultView.ChartArea.ItemClick' event.
2 Use the event arguments which include information on the clicked item.


Result
It works only if I uses the mouse, when using touch the event is never beng promoted (might be because the chart is hosted inside scatterviewitem) . I have tried to bypass this issue without success.

Any workaround exists on current version will be much helpful.

Sincerely,
Guy

Hi, i need to print the RadMap on a Paper with format A0 (big dimension), it's possibile ?
Actually for print the map use the code on the post:http://www.telerik.com/community/forums/wpf/map/print-copy.aspx
it's work but the dimension of the map is the dimension on the screen resolution.

Thanks

Hello, I am new with Telerik controls, but it's making my applications looks much better.
But I have a problem, My application has a RadTabControl with 4 RadTabItem, and the RadTabItems contains a grid with a RadGridView with an ItemsSource, this is the one that is wrong:


I have ser my RadGridView "gridStatus" Height, Width and ColumnWidth to Auto, but in runtime I get an extra column and the content does not fit the width of the RadGridView ( I attach a screen print)

I have tried to set Height and Width in Page1.xaml.cs but I can´t set it to Auto, because the value has to be a double.

But the weirdest thing is that I have another RadGridView that works fine, I copied the code from this to the other, and removed a column that I didn't need, and it was the same, the properties are set to Auto, but I have an "extra column".

Hope you can help me because I have no idea of what to to.
Thanks!

Hi,

I am trying to add a new row to RadGridView. I can add new row, BUT It doesn't allow me to enter more than 4letters in the new row. Could you check this and let me know what went wrong?

Attached screenshot.

Thank you,

Hi,
In application we are using the Grid where one of the column has "DateTime" data type.
I am using RadDataFilter to filter the column values, for this particular column when data filter comes up it comes with the DateTimePicker.
Inside this DateTimePicker if user types "Today" it converts the string into Today's DateTime
I want to stop this behavior so that if user types "Today" it will consider it as a string and
should not convert into corresponding DateTime value.
How can i achieve this?

Hi all,

I am following the example given in WPF demo -> Controls -> Visualization -> Chart -> Performance -> Live Data, in particular, I am looking at this line of code: 
In my data set, I am updating over 20 line series every second, and resetting the view data with this.Data = null and this.Data = this.cpuData seems to be incredibly slow. Is there a better way to update the chart with live data?

Thanks,
Jin

Hello,
I tried to use RadColorPicker ContentTemplate property (example in Telerik manuals). But I get exception:
The attachable propert 'ContentTemplate' was not found in type 'RadColorPicker'.


What happened?

version: RadControls for WPF Q1 2012 SP1

I'm exporting my radgrid to Excel, that part is working great.  What I'm having trouble with is one of the columns in the gridview is a listbox, so in my export, I want to export the list.  I do have that working correctly, I'm getting all items in the list.  Where I'm stuck is I want each item in the list to be on a different line in the Excel cell, so when it exports and I open Excel I want to see

Item A
Item B
Item C

what I currently get is Item A Item B Item C

Below is my code, is there something obvious I'm missing to accomplish this?

if

 

 

(e.Element == ExportElement.Cell)

 

{

 

 

if (e.Value is SurveyDetail)

 

{

 

 

SurveyDetail surveyDetail = (SurveyDetail)e.Value;

 

 

 

if (e.Context is Telerik.Windows.Controls.GridViewDataColumn)

 

{

Telerik.Windows.Controls.

 

GridViewDataColumn dc = (Telerik.Windows.Controls.GridViewDataColumn)e.Context;

 

 

 

if (dc.Name == "dcCPUJobCode")

 

{

 

 

StringBuilder sb = new StringBuilder();

 

 

 

foreach (CPUJobCode cpuJobCode in surveyDetail.SurveyJobCode.CPUJobCodes)

 

{

sb.Append(

 

string.Format("{0} {1} \n", cpuJobCode.JobCode, cpuJobCode.JobTitle));

 

}

e.Value = sb.ToString();

}

}

}

}
