Hierarchical sub grid sharing column headers with parent

Hi,

we would like to have a simple hierarchical GridView with sub grid that is shown after expanding a row, as usual.

The catch is that we want the subgrid in row details to be sharing the same column headers (i.e. columns) with the original parent grid, since the data in the parent and child grids is of same structure. That way we save on introducing another header showing same column headers and the UI becomes cleaner and easier to understand.

Note that functionality like resizing columns should still be working, i.e. resizing both main and sub grids. We are not that concerned about grouping, but I suppose it would be nice for it to still work on the parent grid at least.

What is the best way of implementing this?

Thanks,
Stevo

DataFormDataField derivation for RadMaskedNumericInput has problems

Hello,
I derived the DataFormDataField class to return a RadMaskedNumericInput control. Three problems are readily apparent.

1. The DataMemberBinding does not propagate to the control from the DataFormDataField derivative.
2. The IsReadOnly property is not propagated to the control.
3. The Width property of the DataFormDataField class does not effect the Width of the control.

Here's the code...

/// <summary>

/// Numeric specific <c>DataFormDataField</c>.

/// </summary>

public class DataFormNumericField : DataFormDataField

{

/// <summary>

/// Returns a control to display and edit the underlying data.

/// </summary>

/// <returns><c>Control</c></returns>

protected override Control GetControl()

{

RadMaskedNumericInput ctrl = new RadMaskedNumericInput();

return ctrl;

}

You'll notice below, there is an extension to the DataFormDataField that sets the width of the label portion. Other than that, it is a standard DataFormDataField derivation.

<amUI:DataFormNumericField x:Name="BatchNumberField"

DataMemberBinding="{Binding SelectedBatch.JournalEntryBatchNumber,

ValidatesOnDataErrors=True,

ValidatesOnExceptions=True,

NotifyOnValidationError=True,

UpdateSourceTrigger=PropertyChanged}"

Label="{x:Static localProperties:Resources.Batch_Number}"

Width="163"

amUI:DataFormColumn.LabelColumnWidth="80"

IsReadOnly="True">

<amUI:DataFormNumericField.Resources>

<Style TargetType="telerik:RadMaskedNumericInput">

<Setter Property="Placeholder"

Value=" " />

<Setter Property="SelectionOnFocus"

Value="SelectAll"/>

<Setter Property="IsClearButtonVisible"

Value="False" />

<Setter Property="AllowSkipPlaceholders"

Value="False" />

<Setter Property="AutoFillNumberGroupSeparators"

Value="False" />

<Setter Property="AutoFillZeros"

Value="False" />

<Setter Property="Mask"

Value="#10" />

</Style>

</amUI:DataFormNumericField.Resources>

</amUI:DataFormNumericField>

Could you provide an example where these three issues are addressed?

Thanks in advance,
Steve

ChartTrackBallBehavior CommandParameter Issue

Hi,
first of all I'm using the MVVM pattern.

In order to get the ActualVisibleRange from my DateTimeContinuousAxis i hooked up to the LayoutUpdated event and passed the axis via the CommandParameter:

<telerik:DateTimeContinuousAxis x:Name="horizontalAxis" LabelFormat="dd.MM hh:mm" LabelFitMode="MultiLine">

<i:Interaction.Triggers>

<i:EventTrigger EventName="LayoutUpdated">

<i:InvokeCommandAction Command="{Binding LayoutUpdatedCommand}" CommandParameter="{Binding ElementName=horizontalAxis}"/>

</i:EventTrigger>

</i:Interaction.Triggers>

</telerik:DateTimeContinuousAxis>

When I apply this pattern to the ChartTrackBallBehavior to pass the Data of the Behavior i got an error:

<telerik:ChartTrackBallBehavior x:Name="trackBallBehavior" ShowTrackInfo="True">

<i:Interaction.Triggers>

<i:EventTrigger EventName="TrackInfoUpdated">

<i:InvokeCommandAction Command="{Binding TrackInfoUpdatedCommand}" CommandParameter="{Binding ElementName=trackBallBehavior}"/>

</i:EventTrigger>

</i:Interaction.Triggers>

</telerik:ChartTrackBallBehavior>

Is there an alternative way to pass the data of the ChartTrackBallBehavior to my ViewModel?

Change chart palette

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
