[Solved] Binding Issue (v2010.3.1314.40)

Hi,

I'm having an issue binding with the RadDatePicker. I'm using WPF, .NET 4.0 and RadControls for WPF Q3 2010 SP1. I'm trying to bind to a property on a view model that implements INotifyPropertyChanged, but it never seems to update the source.

On the xaml:

<telerik:RadDatePicker HorizontalAlignment="Left"

Margin="28,90,0,0"

Name="radDatePicker1"

VerticalAlignment="Top"

Width="223"

SelectedValue="{Binding Path=BoundDate}" />

On the view model:

/// <summary>

/// Gets the BoundDate property.

/// Changes to that property's value raise the PropertyChanged event.

/// This property's value is broadcasted by the Messenger's default instance when it changes.

/// </summary>

public DateTime BoundDate

{

get

{

return _boundDate;

}

set

{

if (_boundDate == value)

{

return;

}

var oldValue = _boundDate;

_boundDate = value;

// Update bindings and broadcast change using GalaSoft.MvvmLight.Messenging

RaisePropertyChanged(BoundDatePropertyName, oldValue, value, true);

}

Thanks in advance,
Wyatt

[Solved] Filter a second time

After applying one filter, clearing it, then applying a second filter, The results for the first filter show again.

Steps to recreate Using your demo app and the column filters:
1. Did a contains search for "get_" (See attached image getsearch.png)
2. Cleared the search.
3. Did a contains search for "set_"
4. Results that displayed were the intial "get_" results (notice results for setsearch.png are the same as getsearch.png)

I am having the same issue when adding and clearing FilterDescriptors programmatically on the TreeListView.FilterDescriptors collection.

Filters now display [null] instead of nothing

Hi -
We're upgrading our WPF application from Telerik control version 2010.2.0924 (WPF 3.5) to 2011.3.1116 (WPF 4.0).

The issue we're having is that the column filters now behave differently when there are cells that are empty. In the old version, the grid filter would display a checkbox with nothing next to it. In the new version, the checkbox has [null] or [empty] next to it ([null] for number columns, [empty] for string columns).

Please see the attached files that illustrate the behavior. We need the UI behavior to look as it did before, displaying nothing next to the checkbox.

Can this be fixed with the next service pack?

Thanks,
Sandy

Possibility to known the STorageId

Hi,

I have a generic class to persist (load/save) RadControls from/to disk and I in my class I catch different exceptions. I would like to know if it's possible to know the StorageId my class trying to persist because when I'm catching an exception, I would like to log the StorageId in my log file?

Disappearing Properties

I have discovered what I believe is a bug in PropertyGrid.

Here is a simplified explanation of the issue.

I have a MainWindow that has a PropertyGrid that has its Item property bound to a CurrentWidget. I have a ListBox that has its ItemSource bound to a Widgets collection and its SelectedItem bound to CurrentWidget (TwoWay).

I have a MainWindowViewModel that has a CurrentWidget property and a Widgets collection (Observable).

The Widget class just has four basic properties (ints, bools).

As you click through the Widgets in the ListBox (or arrow up/down), the properties of the selected widget are loaded into the PropertyGrid, but as you move through the items one less property is added to the PropertyGrid until the property count is zero and then it starts back at all of the properties and continues to work down to zero properties, etc.

We have noticed that this is only happening when we have AutoGeneratePropertyDefinitions set to true (the default).

I have created a small proof-of-concept application that isolates and illustrates the bug. Please advise on how to get this to you guys.

Thanks in advance!

Can't load RadDocking after saving the layout to IsolatedStorage

Using the DockingCustomPropertyProvider I save the docking settings. When I try to load them back up, (after I have unpinned a panel) I get the following error: The given key was not present in the dictionary.

Child table ignoring relationship

Hi,
I have a single data context and within my edmx model I have 2 tables.

Table 1 (Parent Table) (Loads grdSAPBatches)
AUFNR Primary key
BATCH_Type
ENGINE_TYPE
START_DATE
START_TIME
PROGRAMMED_QTY

Table 2 (Child Table) (Loads grdSAPComponents)

AUFNR FK1
TAG_POSITION FK2
COMPONENT
MESSAGE

I have a Grid and I have set as follows following the sample to show Table 1 data and on expand of row I would want to see filtered table 2 data with the relationship being AUFNR - but the child table seems to be ignoring the relationship I specified in xaml and just loading all the table 2 data?

I have changed self reference to False and True and it makes no difference....

The VB I am using to load the data is as follows

Dim vwSAPBatchesViewSource As System.Windows.Data.CollectionViewSource = CType(Me.FindResource("TblSAP_BatchesViewSource"), System.Windows.Data.CollectionViewSource)

vwSAPBatchesViewSource.Source = context.fnGetSapBatches

Child Table

Dim vwSAPComponentsViewSource As System.Windows.Data.CollectionViewSource = CType(Me.FindResource("TblSAP_ComponentsViewSource"), System.Windows.Data.CollectionViewSource)

vwSAPComponentsViewSource.Source = context.fnGetSapComponents

The bold items are the imports in edmx to SP's in sql server - neither fn's take parameters as I assumed the grid would filter the child data automatically once the relationship was set?

RadDocking Multiple Custom Themes?

Hello,

I am attempting to theme two different RadDocking controls, within the same solution, each with its own custom theme. I have followed the instructions/example mentioned here and have been able to get the first theme applied. Is it possible to create a second theme to be applied to another RadDocking control?

I would also like to apply each theme in XAML, as demonstrated here in the RadDockingTheming Overview.

Thanks,
Frankie
