[Solved] Open Sub-Menus on mouse over to to reduce clicks

First off, thank you for adding the sub-items on the hamburger menu, it's a great feature.

I'm trying to reduce the number of clicks a user has to perform to get to a sub-menu in the worst-case scenario if they are already looking at an open sub-menu and want to go to another sub-menu of a different option it can take 3 clicks.

1st Click closes the sub-menu of the current item
2nd Click opens the sub-menu of the new item
3rd Click activates the sub-menu On Click event.

Is there a way to have the sub menus automatically open on mouse over to reduce this to one click?

Thanks,
Richard

Multiple areas in RadChartView

I've read in the docs that RadChart supports charts with multiple areas for its series. Is there any way to get something similar in RadChartView?

In case it helps, what I'm trying to achieve is to "stack" vertically different series (candlestick, lines, bars) sharing one common horizontal axis but each with its individual vertical axis.

Setting ITickProvider causes crash or freeze of Visual Studio 2019

Hello,

in my code I want to set the MajorTickLength.

But if I do that, the Visual Studio Designer freeze or crashed with a Out of Memory Exception.

<controls:RadScheduleView x:Name="MapScheduleView" Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2"
NavigationHeaderVisibility="Collapsed"
MinAppointmentHeight="5"
>
<controls:RadScheduleView.ActiveViewDefinition>
<controls:TimelineViewDefinition MinTimeRulerExtent="1" MaxTimeRulerExtent="Infinity" ShowTimeRuler="False"
StretchAppointments="True" StretchGroupHeaders="True">
<controls:TimelineViewDefinition.MajorTickLength>
<provider:OneYearTick/>
</controls:TimelineViewDefinition.MajorTickLength>
</controls:TimelineViewDefinition>
</controls:RadScheduleView.ActiveViewDefinition>
</controls:RadScheduleView>

The tick provider:

public class OneYearTick : ITickProvider
{
public string GetFormatString(IFormatProvider formatInfo, string formatString, DateTime currentStart)
{
return string.Empty;
}
public DateTime GetNextStart(TimeSpan pixelLength, DateTime currentStart)
{
return currentStart.AddYears(1);
}

}

Watermark Text Box additional content IsBackgroundVisible not working

I'm am trying to create a search with Watermark Text Box and have a clear button at the end. The problem is that I can't get the background of the button to be transparent.

This is the code that I am using:

<telerikControls:RadWatermarkTextBox Name="SearchBox"

Text="{Binding SearchControl.SearchText, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"

Width="250">

<telerikControls:RadWatermarkTextBox.WatermarkContent>

<StackPanel Orientation="Horizontal">

<telerikControls:RadGlyph Glyph="" Margin="0 3 0 0"/>

<TextBlock Margin="3,3,0,0" Text="Search" />

</StackPanel>

</telerikControls:RadWatermarkTextBox.WatermarkContent>

<telerikControls:RadWatermarkTextBox.AdditionalContent>

<telerikControls:RadButton Focusable="False"

IsBackgroundVisible="False"

Command="telerikControls:RadWatermarkTextBoxCommands.Clear"

CommandTarget="{Binding ElementName=SearchBox}"

ToolTip="Clear">

<telerikControls:RadGlyph Glyph=""/>

</telerikControls:RadButton>

</telerikControls:RadWatermarkTextBox.AdditionalContent>

</telerikControls:RadWatermarkTextBox>

I have also tried to use Background="Transparent" but that still doesn't work.

I have also noticed that IsBackgroundVisible aslo doesn't work on buttons outside of the Watermark Text Box.

I have attached a photo of how the search box looks.

Need Popup for DefineEnum based Enums

Hello,

I cannot get a C# enumeration property based on dynamically created DefineEnum call to show up as popup on a PropertyGrid. I've tried several things but nothing worked. Also, I am dynamically creating the PropertyDefinition items instead of statically defining anything via XAML.

Here is the basic code to load the property definitions:

private void Window_Loaded(object sender, RoutedEventArgs e)

{

PropertyDefinitionCollection properties = EditorPropertyGrid.PropertyDefinitions;

List<KeyValueBase> testList = new List<KeyValueBase>();

TestEnumKeyValue first = new TestEnumKeyValue() { Key = "Static Enum Prop", Value = TestEnum.test3 };

testList.Add(first);

properties.Add(new PropertyDefinition()

{

DisplayName = first.Key,

Binding = new Binding("Value") { Source = first }

});

DynamicEnumBuilder _enums = new DynamicEnumBuilder();

_enums.BuildDictionaries();

Type dynamicEnum = _enums.getEnum("Employee", "Status");

EnumKeyValue second = new EnumKeyValue() { Key = "Dynamic Enum Prop", Value = Enum.Parse(dynamicEnum, "PartTime")};

testList.Add(second);

properties.Add(new PropertyDefinition()

{

DisplayName = second.Key,

Binding = new Binding("Value") { Source = second }

});

// ************************

EditorPropertyGrid.Item = testList;

}

Here are the key value pair definitions:

enum TestEnum

{

test1,

test2,

test3

}

class KeyValueBase

{

}

class TestEnumKeyValue : KeyValueBase

{

public string Key { get; set; }

public TestEnum Value { get; set; }

}

class EnumKeyValue : KeyValueBase

{

public string Key { get; set; }

public object Value { get; set; }

}

Here is the XAML:

<Grid x:Name="EditorGrid">

<telerik:RadPropertyGrid x:Name="EditorPropertyGrid" Margin="10,10,10,10" DescriptionPanelVisibility="Collapsed" SearchBoxVisibility="Collapsed" AutoGeneratePropertyDefinitions="False" NestedPropertiesVisibility="Visible" AutoGenerateBindingPaths="False" SortAndGroupButtonsVisibility="Collapsed" />

</Grid>

And here is how I generate the dynamic enum:

class DynamicEnumBuilder

{

public Dictionary<string, Dictionary<string, Type>> _enumDictionary = new Dictionary<string, Dictionary<string, Type>>();

public void BuildDictionaries()

{

Dictionary<string, Dictionary<string, List<ValuePair>>> _rawDictionary = new Dictionary<string, Dictionary<string, List<ValuePair>>>();

_rawDictionary["Employee"] = new Dictionary<string, List<ValuePair>>();

_rawDictionary["Employee"]["Status"] = new List<ValuePair>();

_rawDictionary["Employee"]["Status"].Add(new ValuePair() { Name = "FullTime", StoredValue = "1" });

_rawDictionary["Employee"]["Status"].Add(new ValuePair() { Name = "PartTime", StoredValue = "2" });

_rawDictionary["Employee"]["Status"].Add(new ValuePair() { Name = "Retired", StoredValue = "3" });

BuildValueDictionary(_rawDictionary);

}

private void BuildValueDictionary(Dictionary<string, Dictionary<string, List<ValuePair>>> _rawDictionary)

{

// Get the current application domain for the current thread.

AppDomain currentDomain = AppDomain.CurrentDomain;

//// Create a dynamic assembly in the current application domain,

//// and allow it to be executed ONLY, NOT to be saved on disk!

AssemblyName aName = new AssemblyName("TempAssembly");

AssemblyBuilder ab = currentDomain.DefineDynamicAssembly(

aName, AssemblyBuilderAccess.Run);

// Define a dynamic module in "TempAssembly" assembly. For a single-

// module assembly, the module has the same name as the assembly.

ModuleBuilder mb = ab.DefineDynamicModule(aName.Name);

foreach(var fieldEntry in _rawDictionary)

{

Dictionary<string, Type> valueTableDic = null;

if (!_enumDictionary.ContainsKey(fieldEntry.Key))

{

valueTableDic = new Dictionary<string, Type>();

_enumDictionary.Add(fieldEntry.Key, valueTableDic);

}

else

{

valueTableDic = _enumDictionary[fieldEntry.Key];

}

Dictionary<string, List<ValuePair>> rawEnumDict = fieldEntry.Value;

foreach (var fieldEnum in rawEnumDict)

{

// Define a public enumeration with the name "Elevation" and an

// underlying type of Integer.

EnumBuilder eb = mb.DefineEnum(fieldEnum.Key+"Enum", TypeAttributes.Public, typeof(int));

// build the enumerations

List<ValuePair> values = fieldEnum.Value;

foreach (var valuePair in values)

{

eb.DefineLiteral(valuePair.Name, int.Parse(valuePair.StoredValue));

}

// Create the type and save the assembly.

Type dynamicEnum = eb.CreateType();

// now put it in the value dictionary

valueTableDic[fieldEnum.Key] = dynamicEnum;

}

public Type getEnum(String tablename, String fieldname)

{

Type result = null;

if (_enumDictionary.ContainsKey(tablename))

{

Dictionary<string, Type> fieldDict = _enumDictionary[tablename];

if (fieldDict.ContainsKey(fieldname))

{

result = fieldDict[fieldname];

}

return result;

}

Basically, I want the dynamic Enum to have a popup like the static Enum, instead of PropertyGrid rendering it as a string.

Any help will be deeply appreciated!

Thanks in advance!
