Show the datetimepicker in dropped down mode when a gridview cell is selected

I have a RadGridView in Winforms and a date time cell which when clicked will show the text edit mode and a drop down arrow to the right. On clicking the drop down arrow the nice calendar date picker shows.

I'm trying to get the calendar to show straight away but can't find a method on the calendar object. My current code is as follows;

Private Sub OrderGridView_CellEditorInitialized(sender As Object, e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles OrderGridView.CellEditorInitialized

Console.WriteLine("Editor init: {0}", e.ToString())

Dim editor = TryCast(OrderGridView.ActiveEditor, RadDateTimeEditor)

If (editor IsNot Nothing) Then

Dim calendar = DirectCast(editor.EditorElement, RadDateTimeEditorElement)

calendar.GetCurrentBehavior().DateTimePickerElement.Visibility = Telerik.WinControls.ElementVisibility.Visible

calendar.PerformClick()

calendar.Select()

End If

End Sub

Is there a way to do this? Perhaps if not possible, I'll fake a click to the drop down button.

Thanks in advance

Programmically reordering columns

I have a simple class that I am binding to a RadListView. Is there a way, after binding occurs, to programmically reorder the columns? I want my ID property field to always show first, followed by the rest of the fields.

Thanks,

Set icon/image based on node level

Morning,

I'm wondering if there is an easy way of setting the image based on a node level in a tree?

GrandParent    -|
                          |
                          Parent -|
                                        |
                                        Child
                                        Child
                                        Child

So for each level, I would be able to use the image list and assign 0 to GrandParent, 1 to Parents and 2 to child. I do not care what the values of the 3 levels are, just its placement in the tree.

Thanks

James

DateFilterDescriptor DateTime?

Hi

How can I filter radGridView (2012.1.321.40) with BindingList<IPresenceLog> on nullable DateTime field "SystemEnd" to get entries with

SystemEnd.Hasvalue=false? Neither the simple FilterDescriptor nor the DateFilterDescriptor seems to work with any of the available FilterOperators.

//public class PresenceLogModel : PresenceLog, INotifyPropertyChanged, IValidatable

//public class PresenceLog : IPresenceLog

//private BindingList<IPresenceLog> _PresenceLogList = new BindingList<IPresenceLog>();

private void BindDataSource()

{

if (radGridViewPZE.Columns.Count == 0)

{

radGridViewPZE.MasterTemplate.AutoGenerateColumns = false;

radGridViewPZE.DataSource = _PresenceLogList;

radGridViewPZE.Columns.Add(CommonFunctions.NewTextCol("ResourceNo", "Resource", 100, true));

radGridViewPZE.Columns.Add(CommonFunctions.NewTextCol("ResourceName", "Resourcen Name", 120, true));

radGridViewPZE.Columns.Add(CommonFunctions.NewDateTimeCol("SystemBegin", "Begin", 100, true));

radGridViewPZE.Columns.Add(CommonFunctions.NewDateTimeColWithNull("SystemEnd", "Ende", 100, true));

}

else

radGridViewPZE.DataSource = _PresenceLogList;

}

public static GridViewDateTimeColumn NewDateTimeCol(string fieldname, string title, int width, bool isvisible)

{

GridViewDateTimeColumn col = new GridViewDateTimeColumn(fieldname);

col.Name = fieldname;

col.HeaderText = title;

col.Width = width;

col.IsVisible = isvisible;

col.DataType = typeof(DateTime);

col.FormatString = "{0:dd.MM.yy HH:mm}"; //dd/MM/yyyy HH:mm

return col;

}

public static GridViewDateTimeColumn NewDateTimeColWithNull(string fieldname, string title, int width, bool isvisible)

{

GridViewDateTimeColumn col = new GridViewDateTimeColumn(fieldname);

col.Name = fieldname;

col.HeaderText = title;

col.Width = width;

col.IsVisible = isvisible;

col.DataType = typeof(System.Nullable<DateTime>);

col.FormatString = "{0:dd.MM.yy HH:mm}"; //dd/MM/yyyy HH:mm

return col;

}

private void cmbTBFilterOpenEntries_ToggleStateChanged(object sender, StateChangedEventArgs args)

{

if (cmbTBFilterOpenEntries.ToggleState == ToggleState.On)

{

if (resourceFilterOpenEntries == null)

{

//resourceFilterOpenEntries = new DateFilterDescriptor("SystemEnd", FilterOperator.IsEqualTo, new DateTime?(),true);

resourceFilterOpenEntries = new DateFilterDescriptor();

resourceFilterOpenEntries.PropertyName = "SystemEnd";

resourceFilterOpenEntries.Operator = FilterOperator.IsNull; //FilterOperator.IsEqualTo

resourceFilterOpenEntries.Value = null;

//resourceFilterOpenEntries.IsFilterEditor = true;

}

this.radGridViewPZE.FilterDescriptors.Add(resourceFilterOpenEntries);

if (!(radGridViewPZE.EnableFiltering))

radGridViewPZE.EnableFiltering = true;

}

else

{

this.radGridViewPZE.FilterDescriptors.Remove(resourceFilterOpenEntries);

}

Any suggestions?
Thanks Daniel
