Custom sorting

When setting e.Cancel = true on the event args of RadGridVoew.Sorting event, the grid nevertheless modifies the SortingState of columns.
Say the column was in Descending. In the event handler I set it to Ascending, and set e.Cancel = true.

I expect the final state to be Ascending, but the grid changes it to None, according to its internal logic.

Using Reflector, I can see that UpdateColumnSortStatesOnSort() is called in GridViewDataControl.Sort(), even if sortingArgs.Cancel == true. I believe that that call should be avoided.

Problem with formatting

Hi,
I would like to display the date in the following format : "dd/MM/yyyy hh:mm:ss" instead of the default "dd/MM/yyyy hh:mm", or in other words, I want to add seconds.
I've tried the following :

CultureInfo cultureInfo = new CultureInfo("es-ES");

DateTimeFormatInfo dateInfo = new DateTimeFormatInfo();

dateInfo.ShortDatePattern = "dd/MM/yyyy hh:mm:ss";

cultureInfo.DateTimeFormat = dateInfo;

RadDateTimePicker newTime = new RadDateTimePicker();

newTime.Culture = cultureInfo;

But I encounter a strange problem. I get the following format : "dd/MM/yyyy hh:mm:ss hh:mm".
What am I doing wrong?

Thank you

RadDatePicker tooltip on validation error from viewmodel

Hi,

I'm trying to set the tooltip on the RadDatePicker when I get a validation error from my viewmodel.

<Trigger Property="Validation.HasError"Value="True">

<Setter Property="FrameworkElement.ToolTip"

Value=

"{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors).CurrentItem, Converter={StaticResource edenValidationErrorToolTipConverter}}"

TargetName="PART_DateTimeInput" />

</Trigger>

No matter what I try, I can't seem to update the tooltip.

Thanks,
Andy

Auto row update on value change

Hello,

I wish to bind the GridView to a sql server datasource and I wish that when I update the table in the database, the GridView will automatically update the rows values. I want to achieve this without reloading the datasouce of the gridview.
Now I get the values from the datasource into a datatable and then set the datatable as the source of the GridView so there is no direct connection between the database and the GridView. Is there a way to give the GridView a "SELECT statement" and it will autocheck for changes?

Thank you

SelectedDate prior to SeletectableDateStart

I have a raddatepicker with the SelectedDate bound to a date property on my model and the SelectableDateStart set to a value 30 days prior to the current date (DateTime.Now). The date that SelectedDate it is bound to can be earlier than the SelectableDateStart and that is perfectly acceptable. What I want is the control to display the bound date no matter what it is but only allow edits within the range set by SelectableDateStart and SelectableDateEnd. Is this possible?
