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

RadCalendar Special days

Hi,

This is a bit strange, but I cannot get the radCalendar special days to work when adding them from code. The special days just doesn't show up on the calendar. What I want is for them just to be Bolded or marked like when they are added in design time, so nothing fancy.

I have tried the example project from this post: http://www.telerik.com/community/forums/winforms/calendar-and-datetimepicker/calendar-specialdays.aspx and a bunch of other stuff, but nothing seems to work. Adding them in design time makes them show up just fine though.

Any help is appreciated

Solution? dynamic use of themes

Hello,

After sticking a while how to use themes dynamicly we found a simple solution, don't imaging why the ThemeResolutionService not instances the required theme.

ThemeResolutionService provides several methods to register a theme so we ware expecting he loads also the theme and instances it if required by setting ApplicationThemeName. It doesn't do so.

Our solution is quiet simple. Take a Dictionary<string, RadThemeComponentBase> in class being alive the whole time your application runes (static class or like us in the AddIn class). If a theme is required so check your dictionary if theme is loaded otherwise create object (f.i. with Activator.CreateInstance<...>()) and add it to the dictionary. Now the theme is alive and each change on ThemeResolutionService.ApplicationThemeName uses the living theme.

private void AddinModule_OfficeColorSchemeChanged(object sender,

OfficeColorScheme theme)

{

string themeName = string.Format("Office2010{0}",

theme);

if (!this.themes.ContainsKey(themeName))

{

switch (theme)

{

case OfficeColorScheme.Black:

this.themes.Add(themeName,

Activator.CreateInstance<Office2010BlackTheme>());

break;

case OfficeColorScheme.Blue:

this.themes.Add(themeName,

Activator.CreateInstance<Office2010BlueTheme>());

break;

case OfficeColorScheme.Silver:

this.themes.Add(themeName,

Activator.CreateInstance<Office2010SilverTheme>());

break;

}

ThemeResolutionService.ApplicationThemeName = themeName;

}

Hope it helps others
