Hi,
There is a popular samplae called DrawCli in MFC for drawing different kind of shapes using drag and drop.
Anybody have already rewritten this sample using WPF?
here is the WinForm (C#) version of this sample.

Thank you in advance.

Hi,

I want to bind a DbDataReader (System.Data.Common) to my GridView.

I tried to bind it via INotifyPropertyChanged, but this is impossible with the DbDataReader. So I tried the following code:


But there happens nothing. How can I bind the datareader to the gridview?

I'm using Visual Studio 2008, .NET 3.5 and RadControls_for_WPF35_2011_2_0920

Thank you for any suggestions!

I have a RadGridView with auto column generation on, and the data source is a DataTable whose dimensions are unknown at compile time. I would like to make all decimal fields in the grid use money format, like "$#,##0.00".  Notice that I can easily set the FontFamily for text fields.  If only I could set a simple "NumericFormat=..." value !!

When the columns are unknown I cannot write XAML to declare nor to format each column. I could use C# code-behind, but what event shall I catch, and which method sets the numeric formatting at the right time?  Thanks.

 

<telerik:RadGridView Margin="0,22,0,0" Name="radGridView1" DataLoadMode="Asynchronous" FontFamily="Century Gothic" FontSize="16" AutoExpandGroups="True" AutoGenerateColumns="True" >

 

 </telerik:RadGridView>

Hi,
I have a gridview, and I would like to scroll it down every time I add an entry.

How can I do this?

Is there any good tutorial/example to create a splash screen using WPF?

tks in advance

Is it possible to resize RadListBox items with a GridSplitter?

The following code doesn't work but shows what I want to achieve:

Dear Support!

I have been unable to find the backend (C#) code to produce a ScatterLineSeries Chart.

A small snippet of code would be very helpful.

Thanks,

Working through some sample code with GanttView, and I'm wondering if I am able to do any of the following either by some level of re-templating or via support that I haven't yet discovered with the control's OM:

1. In-line labeling of milestones or summary tasks. I believe the control will apply a label inline with a task (shows up in the interior of the task timeline graphic). Can I do something similar for milestone diamonds and summary tasks?

2. Rollup views. Is there a way that I can show, for example, milestones or tasks laid on top of/inline with a summary task? E.g, can I get the same 'task rollup' functionality that we have today in Microsoft Project?

3. In general, is there some sample XAML that demonstrates changing the appearance of tasks/milestones/summary tasks?

Thanks!
