Hi, I'm having a problem when editing a double number in the TreeListView. The comma separator for our culture is ','. When editing a cell in the grid it changes to '.'. If the new number inserted contains ',' instead of '.' the number returned in the CellEditEnded event handler contains no comma even before I try to parse it to a double.

Question: A question about Checkbox selection

Hello,

I have to click 2 times in the cell holding the checkbox before I am finally able to change the value of the checkbox on the 3rd click.

My datasource is a dataset. The last two columns of the datatable in the dataset are booleans so they appear as checkboxes on the grid.

I've come up with a partial solution, which I implement in the grids selectionchanged event. I got it down to 2 clicks:

int currCol;

string currColHeaderName;

currCol = ((Telerik.Windows.Controls.GridViewDataColumn)((Telerik.Windows.Controls.GridView.GridViewCellBase)(((Telerik.Windows.Controls.GridView.GridViewDataControl)(gridname)).CurrentCell)).Column).DisplayIndex;

currColHeaderName = ((Telerik.Windows.Controls.GridViewDataColumn)((Telerik.Windows.Controls.GridView.GridViewCellBase)(((Telerik.Windows.Controls.GridView.GridViewDataControl)(gridname)).CurrentCell)).Column).Header.ToString();

if ( currColHeaderName == "<Whatever>")

target_servers.Columns[currCol].DataControl.BeginEdit();

Note. I compare the header names because if I reorder the columns this code would not work if I were looking at the column position.

Is there a 1 click solution out there?

Thanks

Grouping problem

I have a simple GridView
One of the columns is:

<telerikGrid:GridViewDataColumn 
	Header="TDM Node" 
	UniqueName="L1Type" 
	DataMemberBinding="{Binding L1Type, Converter={StaticResource TDMNodeConverter}}"
	/>

Which is using a converter to convert from one set of strings to another

The problem or a bug:
After the data is successfully loaded into the GridView
I am trying to GroupBy this column and get an error

The Error is that the TDMNodeConverter can't convert the value.
So what is happening is the DataGrid trying to execute the TDMNodeConverter on already converted data

Is this a bug? Or am I doing something wrong?

Thanks!

RadNeedle issue

Hello telerikTeam,

I have a question about the radneedle value-property namely what is the simplest way to achieve following:

I have a radgauge for RPM my ticks are going from 1-10, it means that the 1 represent 1000 and 10 = 10000. So my problem is when I set value of the needle to 1000 needle shows something wrong.. I want the the needle stays at 1.

Have I to divide the needle by 1000, or is there a better Way to manage this issue ?

Thnx

Daniel

Strange behaviour with datetime x-axis

Hello Telerik Team,

I have a very strange thing happening with my WPF Chart where I can't find a solution for.

Please see the attached image.

The first two points of each series actually have a very different x-value, but are drawn at the same x axis reagion.

This happens with every series, regardless of scrolling, zooming, sampling.

What can I do to get around this?

best regards

Rowvalidating missing properties

Hi,

I am using a WPF radgridview and the RowValidating event:

Private Sub RadGridView1_RowValidating(ByVal sender As System.Object, ByVal e As Telerik.Windows.Controls.GridViewRowValidatingEventArgs)

e.IsValid =

False

End Sub

According to the documentation, there is a NewValues property which can be used to access the new values, as well as an OldValues property. The OldValues property is there but I don't see NewValues. Also, is there any way to provide an error message for rowvalidating like you can with cellvalidating?

Thanks
