RadDataPager/RadGridView refresh

Trying to get a RadDataPager with a RadGridView to update the list of items when the underlying bound collection changes. I have RadDataPager.Source bound to a property in the viewmodel, and RadGridView bound to PagedSource of the pager. The collection doesn't actually implement any events for changing, so what I'm doing is replacing the value of the bound property with a new collection. I have verified it is a new instance, and that INotifyPropertyChanged is being raised. However the gridview isn't updating until I move to another page, and then move back. I'd expect the datapager to detect the underlying collection has changed, and instruct the gridview that the current page's contents have changed. It doesn't.

What might I be missing?

Permanent change in MainWindow from a child window with out creating an instance of MainWindow!

I have many windows. I want to change in the Mainwindow from a window (window3). Make a label visible in

MainWindow on a button click in window3.

I don't want to create an instance of MainWindow, because that doesn't keep changes in the parent Mainwindow.

How can I do it, kindly?

Thanks in advanced.

Deployment Problem

Hello,

I updated my project to Q3 yesterday. When I published it today (via ClickOnce) I got the following while installing:

Exception occurred loading manifest from file Telerik.Windows.Controls.Input.dll: the manifest may not be valid or the file could not be opened.

Are there any new dependencies in Q3? I just installed it and used update functionality in your VS extension.

Best Regards,
Peter Schmidt

Switch to wait cursor for slow behaviours

Hi!
there are several occasions that the controls do not behave instantly, depending also on the performance capabilities of the current machine and the complexity of the UI.

I see this for instance when expanding/collapsing rows in the RadTreeListView, or expanding/collapsing the RadExpander. Another example is when my user clicks on a grid row and the grid has to switch the display to the editing template of the corresponding column. The same when the user expands a pane in the RadDocking control.

By default these controls do not switch the cursor to the wait cursor, so if these operations take a second to complete, there is no indication that they even have started. So the user tends to click again and again, resulting in strange behavior depending on the occasion.

I'm interesting in just replacing the Arrow cursor with the WaitCursor and not something more complex like using the RadBusyIndicator.

Any solution?

AlternationCount causes columns to shrink

Hi,

It seems that the RadGridViews AlternationCount causes the columns to shrink. This only happens when the RadGridView is nested within a collapsed expander and a scrollviewer.

<ScrollViewer>

<Expander IsExpanded="False">

<telerik:RadGridView AutoGenerateColumns="False"

ColumnWidth="*"

AlternationCount="2"

ItemsSource="{Binding Products}" />

</telerik:RadGridView>

</Expander>

</ScrollViewer>

When I remove the AlternationCount property or set IsEpanded property on the expander to true - it seems to solve the issue.

I am using the latest version of WPF assemblies .net 4.0.

Regards
Eugene

LookupPropertyDefinition with data template

Hi
I have successfully displayed a single property using a LookupPropertyDefinition. The drop down is positioned to the value corresponding the the PropertyGrid value as expected and the other available values are visible when the dropdown arrow is pressed. Here's an example of the XAML:

<telerik:LookupPropertyDefinition x:Name="ccLookupDef"

DisplayName="Lookup Code" Binding="{Binding MyPropCode}"

SelectedValuePath="Code" ItemsSource="{Binding Data.MyCodes, Source={StaticResource proxy}}"

DisplayMemberPath="Description">

</telerik:LookupPropertyDefinition>

I'd would like to apply a data template to the content of the dropdown so I can display formatted content from multiple lookup properties.
I've tried using the EditorTemplate but it fixes the lookup data and no dropdown button is displayed.

Here's the code:

<telerik:LookupPropertyDefinition x:Name="ccLookupDef"

DisplayName="Lookup Code"

SelectedValuePath="Code" ItemsSource="{Binding Data.ChargeCodes, Source={StaticResource proxy}}">

<telerik:LookupPropertyDefinition.EditorTemplate>

<DataTemplate>

<Grid Margin="0 3">

<Grid.ColumnDefinitions>

<ColumnDefinition />

</Grid.ColumnDefinitions>

<Grid.RowDefinitions>

<RowDefinition />

</Grid.RowDefinitions>

<TextBlock Grid.Row="0" Text="{Binding MyPropCode}" />

<TextBlock Grid.Row="0" Grid.Column="1" Margin="26,0,0,0" Text="{Binding Description}" />

</Grid>

</DataTemplate>

</telerik:LookupPropertyDefinition.EditorTemplate>

</telerik:LookupPropertyDefinition>

Is it possible to use a data template with LookupPropertyDefinition?
What have I done wrong here?

Regards
Craig

[Solved] Need to delay the property change

Hi,
I have a project where each change to a property is triggering a complex data calculation to get some metrics in a dashboard. Right now the users like the Numeric up down but times they execute it too fast triggering the calculation a lot of times. I was wondering if there is a way to apply the value changed after a number of sequential clicks. Before going to custom fixes I was wondering if there is way to delay the update when the button is pressed quickly.
Thanks.
