Problem setting ItemsSource of ComboBoxColumn in RowDetails

Hello,

Currently I am trying to set the ItemsSource of a ComboBoxColumn that is in a grid in my RowDetails for a higher level Grid. I would a child table but I currently have other controls in the RowDetails I am binding to plus I don't really think that will fix my problem.

    
            <telerik:RadGridView.RowDetailsTemplate> 
        
                <DataTemplate> 
        
                    <Grid> 
        
                        <TextBlock Margin="125,8,0,0" Text="Rate" TextWrapping="Wrap" TextAlignment="Center" Height="17.001" VerticalAlignment="Top" HorizontalAlignment="Left" Width="70" /> 
        
                        <telerik:RadMaskedTextBox HorizontalContentAlignment="Right" Mask="P" MaskType="Numeric" Margin="127.007,25.001,406,0" HorizontalAlignment="Left" VerticalAlignment="Top" Height="19.96" Width="67.993" /> 
        
                        <telerik:RadGridView AutoGenerateColumns="False" ItemsSource="{Binding Path=Payments, Mode=TwoWay}" Margin="8,53,8,8" ShowGroupPanel="False" AreRowDetailsFrozen="True" > 
        
                            <telerik:RadGridView.Columns> 
        
                                <telerik:GridViewComboBoxColumn ItemsSource="{Binding Path=AllTypes}" DisplayMemberPath="Type" DataMemberBinding="{Binding
            Path=TypeOfPayment}"/> 
        
                                <telerik:GridViewDataColumn  Header="Event" DataMemberBinding="{Binding Path=TypeOfPayment.Type, Mode=TwoWay}" /> 
        
                                <telerik:GridViewDataColumn Header="Amount" TextAlignment="Right" DataMemberBinding="{Binding Path=Amount, Mode=TwoWay}" DataFormatString="{}{0:c}" /> 
        
                                <telerik:GridViewDataColumn Header="Number" TextAlignment="Right" DataMemberBinding="{Binding Path=Term, Mode=TwoWay}" /> 
        
                                <telerik:GridViewDataColumn Header="Period" TextAlignment="Right" DataMemberBinding="{Binding Path=Period, Mode=TwoWay}" /> 
        
                                <telerik:GridViewDataColumn Header="Notes" TextAlignment="Right" DataMemberBinding="{Binding Path=Notes, Mode=TwoWay}" /> 
        
                            </telerik:RadGridView.Columns> 
        
                            <Navigation:RadContextMenu.ContextMenu> 
        
                                <Navigation:RadContextMenu Opened="RadContextMenu_Opened" ItemClick="RadContextMenu_ItemClick"> 
        
                                    <Navigation:RadContextMenu.Items> 
        
                                        <Navigation:RadMenuItem Header="Add" /> 
        
                                        <Navigation:RadMenuItem Header="Delete" /> 
        
                                    </Navigation:RadContextMenu.Items> 
        
                                </Navigation:RadContextMenu> 
        
                            </Navigation:RadContextMenu.ContextMenu> 
        
                        </telerik:RadGridView> 
        
                        <Button Style="{DynamicResource RoundButton}" Click="btnClick" Foreground="{DynamicResource CalculateIcon}" Height="39" HorizontalAlignment="Right" Margin="0,8,8,0" Name="btnGenerate" VerticalAlignment="Top" Width="44">Button</Button> 
        
                    </Grid> 
        
                </DataTemplate> 
        
            </telerik:RadGridView.RowDetailsTemplate>

In the code block above, I tried binding the ItemsSource in the Xaml file to a property that returns a List<T> of what I want to bind to but the combo box shows no options to select which makes me believe that nothing was being loaded into the ItemsSource even though the debugger shows that the property is being accessed. I have also tried to find a way to access the comboboxcolumn in code but I cannot figure out how to access the controls in the RowDetails. If I did something wrong in my binding or if there is someway I could set the ItemsSource, even manually in either Xaml or code, for the ComboBoxColumn in a Grid in my RowDetails, then that would be most helpful.

Decimal problem!

Hi there,

when I insert decimal values in datagrid I get diferent results if pressed ',' or '.'

Eg. value 7,25

When I insert 7,25 with ',' the final result is 725

but

When I insert 7,25 with '.' the final result is 7,25

I want that was indiferent press ',' or '.' the final result was always the same!

I check every char insert on the grid but I Can´t assign olther value to a routed event that is already in use !

    
             void RadGridView1_KeyDown(object sender, KeyEventArgs e) 
        
                    { 
        
                        if (e.Key == Key.Decimal) 
        
                        { 
        
                            e.Handled = true; 
        
                            e.Source = "2"; // ==> error 
        
                        } 
        
                        if (e.Key == Key.OemComma) 
        
                        { 
        
                            e.Handled = true; 
        
                        } 
        
                        if (e.Key == Key.OemPeriod) 
        
                        { 
        
                            e.Handled = true; 
        
                        } 
        
                    }

it's possible when the user press ',' change the value to '.' ?

Any ideias?

Thanks,

RadDocking and DocumentHost Issues

Hello,

I am required to create an interface that has forms within side RadPanes and a WebBrowser control (another others) in the main DocumentHost window. For some reason only a few of the controls within the DocumentHost render at runtime. Also, the controls that do display are not maintaining their position correctly.

See attached image.

How do I accomplish the desired interface? OR What am I doing wrong?

    
            <telerik:RadDocking.DocumentHost> 
        
                            <telerik:RadSplitContainer>

                                                </StackPanel> 
        
                                                <WebBrowser Height="603" x:Name="webBrowser" /> 
        
                                                <StackPanel Name="stackPanel3" Orientation="Horizontal">

                                        </Grid> 
        
                                    </telerik:RadPane>

                        </telerik:RadDocking.DocumentHost>

Thank you and best regards,

GridView Insert Row focus

When using the GridView. If the first thing I click on in the grid is the left panel where the selection/insertion indicator is and hit the Insert Button it doesn't work until I click for a 2nd time. After that it works every time. Do you have a workaround for this as it is a bit clunky usabilitywise?

Selected Item is always the type of item

Hello

I am filling a the items of the RadComboBox in the code behind.

    
                        foreach (LJSDataSet.LJ_DBRow row in dbNew.LJ_DB.Rows)  
        
                        {  
        
                            StackPanel pan = new StackPanel();  
        
                            TextBlock tb1 = new TextBlock();  
        
                            TextBlock tb2 = new TextBlock();  
        
                            tb1.Width = 130;  
        
                            tb1.Text = row.DBNAME;  
        
                            tb2.Width = 90;  
        
                            tb2.Text = row.DBSERV;  
        
                            pan.Orientation = Orientation.Horizontal;  
        
                            pan.Children.Add(tb1);  
        
                            pan.Children.Add(tb2);  
        
                            this.comboDB.Items.Add(pan);  
        
                        }

When I compile the project, the combobox items are displayed as expected. But the SeletedItem always shows the type name
System.Windows.Contols.StackPanel.

How can I avoid this?

Thank you in advance.

Save and Restore all the grid settings?

I have a few grids, for which user can sort, filter, group and reorder columns. Also user can choose what are all columns he/she need to view in grid. All sort, filter, grouping and reordering are done by default, and i did visibility functionality by providing interface like add/remove columns, where user can choose hidden columns to show and visible columns to hide. After this selection i am setting IsVisible property of Grid.Columns in a loop.
Now I need to store all these settings per user basis in database and should load with the same state whenever he returns. Can I have any sample code to achieve this?
