Hi,

I was looking the chart appearance demo and I want to implement something like that, I am using a RadChart with PieSeriesDefinition, a RadRadialGauge and a RadChart with AreaSeriesDefinition, I can't find how to apply the palette, I also have a RadPolarChart and a RadCartesianChart and I have no problem assigning the palette.

I don't know if for the first 3 charts is not possible assign a palette or it works in a different way.

Thanks,

Alberto

RadWindow.Show() behaviour

Hi

I am using a RadWindow as the apps Main window. What i want to do is create a second Window using RadWindow.Show() which means IsModal = false which is what I want. However, when I click into the main window the second window stays on top. How do I get either window to be on top when clicked-in. The only way I can get the mainwindow on top is by minimizing the second window. I need these two windows to be loosely coupled.

Thanks
Rich

ScrollPositionIndicatorTemplate doesn't show all content

I have implemented this on a grid that I have, and I have noticed that even if I click and drag the scroll bar to the very bottom, it doesn't show the bottom-most record. I have also noticed this same behavior in your WPF Example for this feature. Is this a known issue?

RadButton Command in GridViewColumn doesn't Work sometimes

Dear telerik,

I have to fix a problem in our software and we are using a gridview, which contains articles as items.
Each Item has a deletebutton (only visible for the the selected one), which Command is bound on a DelegateCommand (in the ViewModel). We are using the MVVM-pattern.
This button is only for removing the selected item of the gridview and works fine but when i have more than 16 articles in the grid there is always one or two articles, which I can't delete with the button. The other ones work fine.

The routed method doesn't get called in this times and I don't know why. A Button Click Event always works even when the bound command doesn't work.

I don't know where I have to search this mistake and would like to use the command and not the buttonclick.

Did you ever hear of a problem like this? Could you please help me?

Thanks a lot.

Cheers

Frank

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

[Solved] 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

public MainWindow()

{

InitializeComponent();

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

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

{

DataHeader curentHeader = headerList[i];

GridViewBoundColumnBase column;

if (curentHeader.Name == "AMOUNT")

{

column = new CGridViewNumColumn();

}

else

{

column = new GridViewDataColumn();

}

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

{

UpdateSourceTrigger = UpdateSourceTrigger.LostFocus

};

column.Header = curentHeader.Caption;

column.UniqueName = curentHeader.Name;

GridControl.Columns.Add(column);

}

DataContext = DataService.Instance.Data;

}

internal class CGridViewNumColumn : GridViewBoundColumnBase

{

public override FrameworkElement CreateCellEditElement(GridViewCell cell, object dataItem)

{

BindingTarget = RadMaskedTextInput.ValueProperty;

var input = new RadMaskedTextInput

{

HorizontalContentAlignment = HorizontalAlignment.Right,

Culture = CultureInfo.GetCultureInfo("en-GB"),

FormatString = "n2",

Mask = "",

MinWidth = 100,

SelectionOnFocus = SelectionOnFocus.SelectAll

};

input.SetBinding(BindingTarget, CreateValueBinding());

input.LostFocus += InputOnLostFocus;

return input;

}

private void InputOnLostFocus(object sender, RoutedEventArgs routedEventArgs)

{

var input = sender as RadMaskedTextInput;

if (input == null) throw new ArgumentNullException("sender");

if (string.IsNullOrWhiteSpace(input.Value))

{

input.Value = string.Empty;

return;

}

double value;

//Format the number for frontend.

const NumberStyles style = NumberStyles.Float | NumberStyles.AllowThousands;

if (!double.TryParse(input.Value, style, input.Culture, out value))

{

input.Value = "0";

}

input.Text = value.ToString(input.FormatString, input.Culture);

//Format the number for back-end. Extra precisions will be removed.

if (!double.TryParse(input.Text, style, input.Culture, out value))

{

input.Value = "0";

}

input.Value = value.ToString(input.Culture);

}

private Binding CreateValueBinding()

{

var valueBinding = new Binding

{

Mode = BindingMode.TwoWay,

NotifyOnValidationError = true,

ValidatesOnExceptions = true,

Path = new PropertyPath(DataMemberBinding.Path.Path)

};

return valueBinding;
