When I capture text box have value "3500" in "WPF Control Sample -> DataForm->First Look" window as "err_25-sep_1.jpg" in attach file.When code generate,this TextBox will generate is UITestControl as "err_25-sep_2.jpg" in attach file. This is wrong,because if my machine don't have this extension,this Textbox will generate is WpfEdit as "err_25-sep_3.jpg"

BusyIndicator with RadCartesianChart

Hello,

I am trying to implement a BusyIndicator when loading data into a RadCartesianChart.

I have this code:

<telerik:RadBusyIndicator Name="busyInd" HorizontalAlignment="Left" Grid.Row="1" Margin="10,10,0,0" VerticalAlignment="Top" Height="255" Width="372" IsIndeterminate="True">

<telerik:RadCartesianChart x:Name="CartesianChartDemo" Grid.Column="5" Margin="10" Grid.Row="2" Grid.ColumnSpan="3">

<telerik:RadCartesianChart.Behaviors>

<telerik:ChartPanAndZoomBehavior PanMode="Both" ZoomMode="Both"/>

</telerik:RadCartesianChart.Behaviors>

</telerik:RadCartesianChart>

</telerik:RadBusyIndicator>

I load data in the code behind file:

CartesianChartDemo.VerticalAxis = new CategoricalAxis();

CartesianChartDemo.HorizontalAxis = new LinearAxis();

CartesianChartDemo.Grid = new CartesianChartGrid() { MajorLinesVisibility = GridLineVisibility.XY };

string strQuery = "MyQuery";

//Function to get datatable

DataTable dtAlloys = DataRetriever.GetDataTable(strQuery);

BarSeries barSer = new BarSeries();

barSer.ShowLabels = true;

barSer.CombineMode = ChartSeriesCombineMode.Cluster;

BarSeries barSer2 = new BarSeries();

barSer2.ShowLabels = true;

barSer2.CombineMode = ChartSeriesCombineMode.Cluster;

foreach (DataRow drAlloy in dtAlloys.Rows)

{

barSer.DataPoints.Add(new CategoricalDataPoint() { Category = drAlloy["MATERIAL_CODE"], Label = string.Format("{0:N}", drAlloy["WT"]), Value = double.Parse(drAlloy["WT"].ToString()) });

barSer2.DataPoints.Add(new CategoricalDataPoint() { Category = drAlloy["MATERIAL_CODE"], Label = string.Format("{0:N}", drAlloy["TARG"]), Value = double.Parse(drAlloy["TARG"].ToString()) });

}

CartesianChartDemo.Series.Clear();

CartesianChartDemo.Series.Add(barSer);

CartesianChartDemo.Series.Add(barSer2);

I was thinking to add:

busyInd.IsBusy = true;

//Code to load data

busyInd.IsBusy = false;

But I'm not sure if this is the way the BusyIndicator works.

Does anyone has any pointers to accomplish that?

Regards,

Alberto

Text of RadMaskedTextInput not shown

Hi,
I'm developing with VS 2012 and Telerik control version 2013.2.724.40.
I tried to bind string values dynamically to the GridView in code.
The program first reads from a array, where it can decide the type of the column(e.g. string, double). If the data can be presented as a double value, then I create a customized GridView column with RadMaskedTextInput. I'd like to format the number by setting the Text property. The data binding works fine, however, it seems the numbers (e.g. 1000.1) are not shown as expected (e.g. 1,000.10).

I could attach all source code if needed. Thanks in advance.

Regards,
Gong

InitializeComponent();

IList<DataHeader> headerList = DataService.Instance.HeaderList;

for (int i = 0; i < headerList.Count; i++)

GridViewBoundColumnBase column;

if (curentHeader.Name == "AMOUNT")

{

column = new CGridViewNumColumn();

}

else

{

column = new GridViewDataColumn();

}

column.DataMemberBinding = new Binding("DataItemList[" + i + "]")

UpdateSourceTrigger = UpdateSourceTrigger.LostFocus

DataForm Validation

Hello everybody,

I have a dataform with some fields declared as nullable double (i.e. double?). When I start my application, it is OK I have empty fields for the nullable parameters. But if I start to fill one of these fields and then I delete what I have written, I cannot let the field empty again. The field is boxed with a red frame and a validation exception disables end edit button.

Do you have an explanation and a method to let my fields empty ? I tried to modify the validation exception but I cannot find where they are defined.

Thank you !

Regards,

Thomas

Simple way to adjust NavigationHeader's (a border) background color?

Is there a way to change simple elements that are nested inside the ScheduleView's ControlTemplate, like NavigationHeader -- for example the border's background colour--using Style Setters?

Example: I'd like to apply the Windows8 theme, and then specify a different colour for NavigationHeader.

It seems a shame to generate the ControlTemplate's 6100 some-odd lines of XAML to change some minor elements in the ScheduleView's ControlTemplate.

Variable size of DataForm objects

Hello everyone,

I am facing an issue using DataForm. I have an abstract class IBacktestOption and several inherited classes. Let's take only two of them : OptionCall and CallSpread. These classes share 4 arguments with IBacktestOption and have their own arguments.

Here is the IBacktestOption class :

public abstract class IBacktestOption

{

#region fields

private double mGearing;

public double Gearing { get { return mGearing; } set { mGearing = value; } }

private double? mGlobalCap;

public double? GlobalCap { get { return mGlobalCap; } set { mGlobalCap = value; } }

private double? mGlobalFloor;

public double? GlobalFloor { get { return mGlobalFloor; } set { mGlobalFloor = value; } }

public string Nom { get; set; }

#endregion

protected IBacktestOption(double aGearing, double? aGlobalCap, double? aGlobalFloor)

{

Gearing = aGearing;

GlobalCap = aGlobalCap;

GlobalFloor = aGlobalFloor;

}

public abstract Dictionary<DateTime, IResultatsBacktest> GetOptionResults(IBacktesting backtest);

public abstract bool CheckOption();

}

This is OptionCall class :

class OptionCall : IBacktestOption, IEditableObject, INotifyPropertyChanged

{

#region fields

private double mStrike;

public double Strike { get { return mStrike; } set { mStrike = value; } }

OptionCallData backupOptParamData;

private int mID;

public struct OptionCallData

{

internal int ID;

internal double Strike;

internal double? CapGlobal;

internal double? FloorGlobal;

internal double Gearing;

}

public int ID

{

get { return mID; }

}

#endregion Fields

#region constructors

public static OptionCall CreateNewOptionCall(double strike, double gearing = 1, double? cap = null, double? floor = null)

{

return new OptionCall(strike,gearing,cap,floor);

}

public OptionCall(double strike, double gearing = 1, double? cap = null, double? floor = null) : base(gearing,cap,floor)

{

Strike = strike;

Nom = "Call";

}

#endregion

public override Dictionary<DateTime, IResultatsBacktest> GetOptionResults(IBacktesting backtest)

{

/* ... */

}

public override bool CheckOption()

{

return true;

}

#region Edition

public void BeginEdit()

{

}

public void CancelEdit()

{

mStrike = this.backupOptParamData.Strike;

GlobalCap = this.backupOptParamData.CapGlobal;

GlobalFloor = this.backupOptParamData.FloorGlobal;

Gearing = this.backupOptParamData.Gearing;

}

public void EndEdit()

{

this.backupOptParamData.Strike = mStrike;

this.backupOptParamData.CapGlobal = GlobalCap;

this.backupOptParamData.FloorGlobal = GlobalFloor;

this.backupOptParamData.Gearing = Gearing;

}

#endregion Edition

#region Events

public event PropertyChangedEventHandler PropertyChanged;

private void NotifyPropertyChanged(string info)

{

if (PropertyChanged != null)

PropertyChanged(this, new PropertyChangedEventArgs(info));

}

#endregion Events

}

This is CallSpread class :

class CallSpread : IBacktestOption, IEditableObject, INotifyPropertyChanged

{

#region fields

private double mStrike1;

public double Strike1 { get { return mStrike1; } set { mStrike1 = value; } }

private double mStrike2;

public double Strike2 { get { return mStrike2; } set { mStrike2 = value; } }

OptionCallData backupOptParamData;

private int mID;

public struct OptionCallData

{

internal int ID;

internal double Strike1;

internal double Strike2;

internal double? CapGlobal;

internal double? FloorGlobal;

internal double Gearing;

}

public int ID

{

get { return mID; }

}

#endregion Fields

#region constructors

public static CallSpread CreateNewCallSpread(double strike1, double strike2, double gearing = 1, double? cap = null, double? floor = null)

{

return new CallSpread(strike1, strike2, gearing, cap, floor);

}

public CallSpread(double strike1, double strike2, double gearing = 1, double? cap = null, double? floor = null) : base(gearing,cap,floor)

{

Strike1 = Math.Min(strike1, strike2);

Strike2 = Math.Max(strike1, strike2);

Nom = "Call Spread";

}

#endregion

public override Dictionary<DateTime, IResultatsBacktest> GetOptionResults(IBacktesting backtest)

{

/* ... */

}

public override bool CheckOption()

{

return true;

}

#region Edition

public void BeginEdit()

{

}

public void CancelEdit()

{

mStrike1 = this.backupOptParamData.Strike1;

mStrike2 = this.backupOptParamData.Strike2;

GlobalCap = this.backupOptParamData.CapGlobal;

GlobalFloor = this.backupOptParamData.FloorGlobal;

Gearing = this.backupOptParamData.Gearing;

}

public void EndEdit()

{

this.backupOptParamData.Strike1 = mStrike1;

this.backupOptParamData.Strike2 = mStrike2;

this.backupOptParamData.CapGlobal = GlobalCap;

this.backupOptParamData.FloorGlobal = GlobalFloor;

this.backupOptParamData.Gearing = Gearing;

}

#endregion Edition

#region Events

public event PropertyChangedEventHandler PropertyChanged;

private void NotifyPropertyChanged(string info)

{

if (PropertyChanged != null)

PropertyChanged(this, new PropertyChangedEventArgs(info));

}

#endregion Events

}

In my view I have my DataForm declare like this :

<telerik:RadDataForm Grid.Column="1" Margin="12,0,6,21" Grid.ColumnSpan="2" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" ItemsSource="{Binding BacktestOpt}"

CommandButtonsVisibility="Cancel,Commit,Edit,Navigation" Grid.Row="1" Height="456" Grid.RowSpan="2" />

And in my view model I initialize my Collection (I use a ViList, which is a structure almost equivalent to a simple List) with an element of OptionCall type :

private ViList<IBacktestOption> mBacktestOpt;

public ViList<IBacktestOption> BacktestOpt

{

get

{

if (mBacktestOpt == null && Formule == 0)

{

ViList<IBacktestOption> newBacktestOpt = new ViList<IBacktestOption>();

newBacktestOpt.Add(Creators.CreateNewOptionCall(0));

this.mBacktestOpt = new ViList<IBacktestOption>(newBacktestOpt);

Formule = PayoffFormule.CALL;

}

return mBacktestOpt;

}

set

{

mBacktestOpt = value;

OnPropertyChanged("BacktestOpt");

}

When I start my application, everything is fine, I have what I want i.e. my DataForm with my 6 fields : "Strike", "ID", "Gearing", "GlobalCap", "GlobalFloor", "Nom".
In my page, I also have a RadComboBox which enables me to choose which formula I want to use. This combobox is binded to this field in my view model :

private PayoffFormule mFormule;

public PayoffFormule Formule

{

get { return mFormule; }

set

{

mFormule = value;

switch (mFormule)

{

case PayoffFormule.CALL :

Backtest.Option = Creators.CreateNewOptionCall(0);

break;

case PayoffFormule.PUT :

Backtest.Option = Creators.CreateNewOptionPut(0);

break;

case PayoffFormule.ASIAN_CALL:

Backtest.Option = Creators.CreateNewAsianCall(0);

break;

case PayoffFormule.ASIAN_PUT:

Backtest.Option = Creators.CreateNewAsianPut(0);

break;

case PayoffFormule.CALL_SPREAD:

Backtest.Option = Creators.CreateNewCallSpread(0,0.15);

break;

default:

break;

}

BacktestOpt.Add(Backtest.Option);

OnPropertyChanged("BacktestOpt");

OnPropertyChanged("Formule");

}

When I use the ComboBox to change the formula, a new element is added to the DataForm and here is my issue : this new element only have the fields of IBacktestOption class. And when I use Navigation buttons to go back on my first element (OptionCall), the number of fields of the element have been reduced to 4 ("Gearing", "GlobalCap", "GlobalFloor", "Nom").

I want to know if it is possible to have the fields of the inherited classes instead of the ones of IBacktestOption.

Moreover, in reality I don't need to have a list of IBacktestOption in my DataForm, I only need to have the current option (the one which is selected in the combobox). So, I have tried to empty my List when I change the option type in the combobox :

private PayoffFormule mFormule;

public PayoffFormule Formule

{

get { return mFormule; }

set

{

mFormule = value;

BacktestOpt.RemoveAt(0);

switch (mFormule)

{

case PayoffFormule.CALL :

Backtest.Option = Creators.CreateNewOptionCall(0);

break;

case PayoffFormule.PUT :

Backtest.Option = Creators.CreateNewOptionPut(0);

break;

case PayoffFormule.ASIAN_CALL:

Backtest.Option = Creators.CreateNewAsianCall(0);

break;

case PayoffFormule.ASIAN_PUT:

Backtest.Option = Creators.CreateNewAsianPut(0);

break;

case PayoffFormule.CALL_SPREAD:

Backtest.Option = Creators.CreateNewCallSpread(0,0.15);

break;

default:

break;

}

BacktestOpt.Add(Backtest.Option);

OnPropertyChanged("BacktestOpt");

OnPropertyChanged("Formule");

}

It works, I have the good number of fields for each option type. But, I need to click on the Next Item Navigation Button to reach my element. Indeed, the first one is empty. It is not really handy for a user. So, I also want to know if there is a way to click on this button automatically.

Finally, I have a last request. As, I don't really need a List for my elements, I tried to use a IBacktestOption instead of a ViList<IBacktestOption> in BactestOpt field. But I didn't manage to have fields printed in DataForm, the DataForm was empty...

Thank you very much for your help.
Regards,

Thomas
