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,

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?

Cellvalue doesn't retain while editing for dynamically added columns

Hi

I am using TreeListView.
I am adding columns dynamically at runtime

GridViewDataColumn column;

for (int icnt = 1; icnt < ts.Days; icnt++)

{

column = new GridViewDataColumn();
column.UniqueName = "key" + icnt.ToString();
column.IsReadOnly = false;
RadTreeListView1.Columns.Add(column);

}

I am populating the cell data in RadTreeListView1_RowLoaded event.

var row = e.Row as TreeListViewRow;

foreach (GridViewCell cell in row.Cells)

{

if (cell.IsLoaded)
{

DateTime dates;

if (DateTime.TryParse(cell.Column.Header.ToString(), out dates))
{

string filter = "dates = '#" + dates.ToShortDateString().ToString() + "#'";

DataRow[] dr = lobjdt.Select(filter);

if (dr != null && dr.Length > 0)

{

cell.Content = dr[0]["hours"].ToString();

}

}

But I am facing one more diffrent problem.
I want to edit cells of cloumns which I have added dynamically.
I am able to click and edit the data ... but data gets disappeares when user leave the cell and click somewhere else in the window.

Editing is working correctly in static clumns.
Am I missing anything while adding columns ?
