Hi,

I am binding the IsChecked property to a property in my ViewModel with the help of ItemContainerStyle.
When I click on the checkbox of a child "Item 2", I get the following result:

- Group A
   Item 1
x Item 2

So Group A is marked as indeterminate correctly.

When I set Item2.IsChecked  = true in my ViewModel, Item2 is marked as checked, but GroupA is marked as unchecked.

Am I doing something wrong? If not, is there a workaround for this?

Best Regards, Matthias

Hello,
Their if any event in raddatafilter which get fired on each time user filter the records.

I trying to implement a filter in which work like this:
If user select containg string "abc" then i want to show all record those contains "abc" as well as "cde". But i don't want to show user both option "abc" and "cde" because in my case meaning of "abc" and "cde" is same.

There is any other way to do this?

Thanks in advance.

Hi All,

I have a datagrid with one of datacolumn contains a combobox.

DataGrid contains a RowDetails template attached to it.

When i add a row into datagrid on click of button or delete a row from datagrid, selection change event of combobox gets called.

RowDetails template also contains a combobox with a selection change event.

When i am trying to click somewhere inside the rowdetailstemplate or trying to use a template scroll bar, combobox selection change event is getting fired.

Please provide the solution how we can avoid selection change event of combobox in above cases.

Please find below piece of code:

 

 

<telerik:RadGridView ItemsSource="{Binding Path=Customers}"

 

 

IsReadOnly="{Binding IsChecked, Mode=TwoWay, ElementName=IsReadOnlyCheckBox}" RowDetailsVisibilityMode="{Binding RowDetailsTemplateVisibilityMode, Mode=TwoWay}"

 

 

SelectionMode="Multiple" AutoGenerateColumns="False" VerticalAlignment="Stretch"

 

 

ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Visible" MinHeight="100" MaxHeight="350">

 

 

 

<telerik:RadGridView.Columns>

 

 

 

<telerik:GridViewToggleRowDetailsColumn Width="30"/>

 

 

 

<telerik:GridViewSelectColumn Width="30"/>

 

 

 

<telerik:GridViewDataColumn DataMemberBinding="{Binding SlNo}" Header="S.no" IsReadOnly="True" IsEnabled="False" Width="20" />

 

 

 

<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=Product}" Header="Product" IsReadOnly="True" IsEnabled="False" Width="250"/>

 

 

 

<telerik:GridViewDataColumn Header="Customer" Width="Auto">

 

 

 

<telerik:GridViewDataColumn.CellTemplate>

 

 

 

<DataTemplate>

 

 

 

<ComboBox ItemsSource="{Binding Path=Customer}" HorizontalAlignment="Left" DisplayMemberPath="RunDesc" SelectedItem="{Binding RunsSelected}" IsEnabled="{Binding IsEnabledRun}" Style="{StaticResource SmallComboBox}">

 

 

 

<i:Interaction.Triggers>

 

 

 

<i:EventTrigger EventName="SelectionChanged">

 

 

 

<cmd:EventToCommand Command="{Binding Path=LoadCustomersCommand}" PassEventArgsToCommand="False" CommandParameter="{Binding Path=DataContext,RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ComboBox}}"/>

 

 

 

</i:EventTrigger>

I have version 2011.1.419.35 and it seems sorting and filtering does not work when my ItemsSource is a List<dynamic> Is this expected? Is there a workaround or a plan to support this?

Thanks,

I have a RadGridView in my application that is crashing the application on a select few tablet pc running Windows XP tablet editiion. Because our (state) department is going the tablet way, I really need to get this fixed. Not just disable tablet input services on the pc.
I'm thinking the problem is because the grid that is causing the problem is heavily customized with Data Templates.

The crash happens when they attempt to scroll horizontally on an editable grid. It's been reported that if InsertRows and DeleteRows is disabled, then the grid behaves normally. So far this error has only been reported by users running on a tablet pc.

Also, another user reported that when he tried to activate the TabItem where this grid lives, the application crashed only when there were items bound to the grid. If the bound collection had no items, it didn't crash. His problem was resolved by disabling Tablet Input Services on his Windows 7 tablet pc.

Could someone look at my code and see if I've done something I shouldn't.
