Greetings All!

Hi,

With the gridview I need to override the delete functionality...When a user hits the delete key on a row in the grid I want to set my entity to Inactive, rather than remove it from the collection.

I tried hooking up KeyDown but it never fires for the delete key, the default functionality of removing the row happens.
I tired hooking up KeyDown with CanUserDeleteRows set to false and the key down never fires for the delete key.
I can use other keys such as backspace etc. but our users want to use delete.

The only thing that seemed to work was to handle the Deleting event and do what I want and set e.Cancel to true. The problem with this event is I can't selectivly remove from the collection ie. if my record is new/unsaved and they hit delete i want it removed but if it's a saved record that they delete i want it marked on screen as inactive. The cancel seems to be an all or nothing. 

What's the best way to do the functionality that i need?

I downloaded RAD Controls for WPF set and didn't manage to find in Demos an example of master-detail representation of a GridView. For example, for OrderHeader - OrderLines view implementation. How is it possible to set detail part of a view as CardView with the possibility of editing database records?

Hi,

I use the RadGridView and I want to have 2 GridViewComboBoxColumn in there. But there are a lot of problem:
1. The Comboboxes should always be visible, but they are only visible if the user double-clicks in the cell. Therefore, I tried to put a normal Combobox in the DataTemplate of the Cell-Template but then
2. Databinding is not working any more. And
3. Databinding with Enums is not working at all. If I bind my enum to the normal GridViewComboBoxColumn the data is showing up wenn the user double clicks, but then it is not possible to select any other cell in the grid and everything stood still.
4. How can I preselect the current dataitem value in the combobox? The initial value of all comboboxes is always empty ....
Please help!

That's my code:
XAML:
<telerik:RadGridView x:Name="grid" Grid.Column="2" Grid.RowSpan="15" AutoGenerateColumns="False" ItemsSource="{Binding}">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Header="Plate Id" DataMemberBinding="{Binding Name}">            
                <telerik:GridViewComboBoxColumn Header="Dilution Factor" DataMemberBinding="{Binding DilutionFactorId, Mode = TwoWay}" ItemsSource="{Binding}" DisplayMemberPath="Name" SelectedValueMemberPath="Id" UniqueName="colDilFactor">
                    <!--<telerik:GridViewComboBoxColumn.CellTemplate>
                        <DataTemplate>
                            <StackPanel>
                                <ComboBox x:Name="internalCboFactor" ItemsSource="{Binding}" SelectedValue="{Binding DilutionFactorId}"></ComboBox>                               
                            </StackPanel>
                        </DataTemplate>
                    </telerik:GridViewComboBoxColumn.CellTemplate>-->
                </telerik:GridViewComboBoxColumn>
                <telerik:GridViewComboBoxColumn Header="State" DataMemberBinding="{Binding State}" ItemsSource="{Binding}" UniqueName="colState">
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

C#
((GridViewComboBoxColumn)grid.Columns["colState"]).ItemsSource = Enum.GetNames(typeof(PlateStateEnum));
 ((GridViewComboBoxColumn)grid.Columns["colDilFactor"]).ItemsSource =                     _handler.GetProvider().LoadDilutionFactors(typeId);

                //ComboBox cboFactor = grid.Columns["colDilFactor"].FindName("internalCboFactor") as ComboBox;
                //if(cboFactor != null)
                //    cboFactor.ItemsSource = _handler.GetProvider().LoadDilutionFactors(typeId);

            }

Thx in advance!

RadControls for WPF Q3 2009.
I have predefined GroupDescriptors in XAML on the RadGrid, to show a Particular Group at start.
However the AggregateFunctions do not show up on the Group Footers or Headers.  The Group Footers also look broken, as some grid lines are missing.
In the UI, if a user removes the prefined GroupDescriptor, and creates a new group through the UI with the same Column, the AggregateFunctions do show up.

I have also attempted to do this through C#, and get the same results.
Is there a particular way of predefining the GroupDescriptors so the Column's AggregateFunctions show up in the Group Footer?

Additional question.  Is there way of defining a Column AggregateFunction to only appear in the GroupFooter, and not the header without writing a new ControlTemplate for the GridViewGroupRow?

Dear team,

I am getting an error trying to change my column collection after it has been previously loaded.
I am using as much of an MVVM approach as I can, to work around some of the gridview properties that aren't DependencyProperties i had to get a little creative. Everything was working fine, but it seems as if something in the last release(2009.3.1208.35) is causing an error.

I have a property in my ViewModel that is a GridViewColumnCollection. A multibinding converter is used to get the Columns property of the Grid and set it into the ViewModel( which is the Datacontext for the Grid)

My Grid is declared as such:

Here's the Xaml for the column binding converter:

Here's ColumnConverter:

The LoadListToolColumns Method reads through saved column data and creates GridViewDataColumns to add to the ColumnList Object(which since the ColumnList and the GridView.Columns are the same object it will update the UI when the ColumnList is changed).

This was all working fine, and still does work fine the first time it runs, but if I call LoadListToolColumns to try to load a different set of columns( after doing a ColumnList.Clear() ). Then I get an error, it works without error using version 2009.3.1103.35. 

This error is thrown after all my code has executed successfully:

Any ideas?

Hi,

Attempt to set .Left and .Top property on RadWindow produces exception.

I’m trying to open modal RadWindow at the specific location on screen. The WindowStartupLocation is set to “Manual”.  The code runs like this :

 

windowAdjustment.Left = _rightClickPoint.X;

windowAdjustment.Top = _rightClickPoint.Y;

windowAdjustment.ShowDialog();

 

It works perfectly the first time. But setting .Left property the second time causes exception “{“Object reference not set to an instance of an object"}            System.Exception {System.NullReferenceException}”

The top of the stack trace :

 

at Telerik.Windows.Controls.RadWindowPopup.WindowPopupWindowFactory.WindowPopupWindowImpl.Move(Double left, Double top) in c:\Builds\...\Navigation\Window\WindowPopup\WindowPopupWindowImpl.cs:line 39

   at Telerik.Windows.Controls.RadWindow.Move(Double x, Double y) in c:\Builds\...\Navigation\Window\RadWindow.cs:line 2028

   at Telerik.Windows.Controls.RadWindow.OnLeftChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) in c:\Builds\...\Navigation\Window\RadWindow.cs:line 1713

 

Any ideas anyone ?
