[Solved] How to create hierarchical grids in Q3 2009?

I ported this silverlight example to WPF and it stopped working. I'm talking about the first project provided by Ross. I didn't change any code (other than the wpf/silverlight stuff) and it doesn't load any row in any of the child tables anymore.

I also took this other example, which is a WPF project already (ticketid-243249-hierarchychildtemplate.zip), switched the dll's for the Q3 release and it stopped working. Same problem, doesn't load any row.

My situation is simple, I wanna be able to create a hierarchy of .NET Objects like the following:

Clients

Offices

Contacts

I need to be able to define each column, I tried this code, which seems the most straight forward approach, but it doesn't let me define any column:

                               <telerik:RadGridView.ChildTableDefinitions>         
                            <telerik:GridViewTableDefinition AutoGenerateFieldDescriptors="False">         
                                <telerik:GridViewTableDefinition.Relation>         
                                    <data:PropertyRelation ParentPropertyName="Offices" />         
                                </telerik:GridViewTableDefinition.Relation>         
                            </telerik:GridViewTableDefinition>         
                        </telerik:RadGridView.ChildTableDefinitions>         

I've tried many other approaches and samples, so far no luck. Any ideas?

F2 Bug

Hi Guys,

I found a bug in treeview when pressing F2 to edit the name. Here is the scenario:

On my screen, left side is a treeview, right side is a textbox. Treeview is bound to an observablecollection. When selecting an item in the treeview, the tree node name is showing on the textbox of right side.

1. Select a treenode (Item1), Textbox shows Item1's name (Item1).
    press F2,
    do not change anything, press enter key.

2. click the textbox of right side, change Item1 to Item2. Since it is bound to ObservableCollection, once it is changed to Item2, treenode is changed accordingly.

3. Select treenode Item2(the same node as Item1 but now named Item2) , hit F2, the treenode displays Item1 instead of Item2

If you don't Press F2 in step1, it works fine. It looks like although the source is changed, when you hit F2, the content showing in F2 box is not refreshed. Please investigate.

Thanks,

Telerik Wpf Grid Check Box in Header of the Cell

Hi,
I am facing a problem which i am demonstrating in the following steps:

a) I take a telerik wpf grid like this:

<

gridviewcontrols:RadGridView local:RadialPanel.ZIndex="0" Name="grdPendingEncounters" AutoGenerateColumns="False"

ShowGroupPanel="False"

CanUserSortColumns="True" ShowColumnFooters="False"

ColumnsWidthMode="Fill"

AreRowDetailsFrozen="True" RowDetailsVisibilityMode="VisibleWhenSelected" RowIndicatorVisibility="Collapsed"

UseAlternateRowStyle="True" Margin="5,1,0,0" ScrollViewer.HorizontalScrollBarVisibility="Visible" ScrollViewer.VerticalScrollBarVisibility="Visible" Opacity="1">

<gridviewcontrols:RadGridView.Resources>

<local:StatusToColorConverter x:Key="MyConverter" />

</gridviewcontrols:RadGridView.Resources>

<gridviewcontrols:RadGridView.RowAppearance>

<gridviewcontrols:RowAppearanceSettings UseAlternateRowStyle="True" RowStyle="{StaticResource GridViewRowStyle}" AlternateRowStyle="{StaticResource GridViewAlternateRowStyle}" />

</gridviewcontrols:RadGridView.RowAppearance>

<gridviewcontrols:RadGridView.Columns>

<gridviewcontrols:GridViewColumn HeaderCellStyle="{StaticResource FirstHeaderCellStyle}" Width="30" IsFilterable="False">

<gridviewcontrols:GridViewColumn.CellTemplate>

</DataTemplate>

</gridviewcontrols:GridViewColumn.CellTemplate>

</gridviewcontrols:GridViewColumn>

<gridviewcontrols:GridViewDataColumn Header="{Resx ResxName=PMS.UserInterface.Resources.UIResource, Key=Date}" HeaderCellStyle="{StaticResource HeaderCellStyle}" DataMemberBinding="{Binding EncounterDate}" IsFilterable="True">

</gridviewcontrols:GridViewDataColumn>

<gridviewcontrols:GridViewDataColumn HeaderCellStyle="{StaticResource HeaderCellStyle}" Header="{Resx ResxName=PMS.UserInterface.Resources.UIResource, Key=Patient}" DataMemberBinding="{Binding Patient}" IsReadOnly="True" IsFilterable="True" />

<gridviewcontrols:GridViewDataColumn HeaderCellStyle="{StaticResource HeaderCellStyle}" Header="{Resx ResxName=PMS.UserInterface.Resources.UIResource, Key=ID}" DataMemberBinding="{Binding EncounterID}" IsReadOnly="True" IsFilterable="True" />

<gridviewcontrols:GridViewDataColumn HeaderCellStyle="{StaticResource HeaderCellStyle}" Header="{Resx ResxName=PMS.UserInterface.Resources.UIResource, Key=Type}" DataMemberBinding="{Binding EncounterType}" IsReadOnly="True" IsFilterable="True" />

<gridviewcontrols:GridViewDataColumn HeaderCellStyle="{StaticResource HeaderCellStyle}" Header="{Resx ResxName=PMS.UserInterface.Resources.UIResource, Key=Provider}" DataMemberBinding="{Binding Provider}" IsReadOnly="True" IsFilterable="True" />

<gridviewcontrols:GridViewDataColumn HeaderCellStyle="{StaticResource HeaderCellStyle}" Header="{Resx ResxName=PMS.UserInterface.Resources.UIResource, Key=Location}" DataMemberBinding="{Binding Location}" IsReadOnly="True" IsFilterable="True" />

<gridviewcontrols:GridViewDataColumn HeaderCellStyle="{StaticResource HeaderCellStyle}" Header="{Resx ResxName=PMS.UserInterface.Resources.UIResource, Key=ClaimNo}" DataMemberBinding="{Binding ClaimNo}" IsReadOnly="True" Width="110" IsFilterable="True" />

<gridviewcontrols:GridViewDataColumn HeaderCellStyle="{StaticResource HeaderCellStyle}" Header="{Resx ResxName=PMS.UserInterface.Resources.UIResource, Key=FinalizedBy}" DataMemberBinding="{Binding FinalizedBy}" Width="130" IsReadOnly="True" IsFilterable="True" />

<gridviewcontrols:GridViewDataColumn HeaderCellStyle="{StaticResource HeaderCellStyle}" Header="{Resx ResxName=PMS.UserInterface.Resources.UIResource, Key=Status}" DataMemberBinding="{Binding Status}" IsReadOnly="True" IsFilterable="True" >

<telerik:GridViewDataColumn.CellStyle>

</Style>

</telerik:GridViewDataColumn.CellStyle>

</gridviewcontrols:GridViewDataColumn>

</gridviewcontrols:RadGridView.Columns>

</gridviewcontrols:RadGridView>

2) Then i set the item source of this grid to null and then to the collection like this:

grdPendingEncounters.ItemsSource =

null;

grdPendingEncounters.ItemsSource = GetObservableObjectData(encountersCollection);

3) Then i am adding the Checkbox in the header of the first column like this dynamically

grdPendingEncounters.Columns[0].Header =

null;

CheckBox checkBox = null;

checkBox =

new CheckBox();

checkBox.Width = (

double)15;

checkBox.Checked +=

new RoutedEventHandler(CheckBox_Checked);

checkBox.Unchecked +=

new RoutedEventHandler(CheckBox_Checked);

grdPendingEncounters.Columns[0].Header = checkBox;

4) but it runs successfully in first go and then in second go it is not showing the check box of the first header.

5) and in third go it shows an error like "Specified element is the logical child of another element .Disconnect it first"

Please Help me out.
Thanks in advance
Shreya

Display item in center of path

I have a horizontal path that my RadCarouselPanel follows. When there are only 1 or 2 items bound to my ListBox (where the RadCarouselPanel is), I want the items to appear in the center of my path instead of on the left side. Is there a way to tell an item to appear in the center of the path?

Drag/Drop Icon

Hi Guys,

I am new to Telerik TreeView control. If I try to drag a node to itself I can see the 'Stop' Icon which means it is a invalid target. What I am trying to do is to set certain nodes to be invalid targets so that when people drag nodes to these targets, they will see the Stop icon. Which event can I catch the drag movement or where else can I do this and how?

Thanks for the help in advance.

AccessKeys do not work when NumericUpDown has focus

It seems that wpf accesskeys do not work when a NumericUpDown field has focus. I was able to reproduce this in a new project with just a label and an NumericUpDown control. Can you offer a work around or bug fix? Please let me know if you need more detail.

Thanks,

Alex

Sometimes my gridview has ItemSource count = 10, but items.count = 0. Sometimes the counts are same. I remembered someone has posted some similar issue but I can't find it any more. Any answers? Also, when should I use grid.Rebind() function?

Thanks,

Redering Artifact

There is a rendering artifact when you place a menu inside a toolbar like so

    
            <t:RadToolBar DockPanel.Dock="Top" Height="25"> 
        
                        <TextBlock Text="Select Job:" Margin="2,2,5,0"/> 
        
                        <t:RadComboBox x:Name="cmbJobs" Width="200" IsTabStop="False" IsEditable="True" StaysOpenOnEdit="True" /> 
        
                        <t:RadMenu Background="Transparent"> 
        
                            <t:RadMenuItem Header="Filter"> 
        
                                <t:RadMenuItem Header="Show All Jobs" Checked="MenuItem_Checked_All" Name="mnuShowAllJobs" IsCheckable="True"/> 
        
                                <t:RadMenuItem Header="Show Unfinished" Checked="MenuItem_Checked_Unfinished" Name="mnuShowUnfinishedJobs" IsCheckable="True"/> 
        
                            </t:RadMenuItem> 
        
                        </t:RadMenu> 
        
                    </t:RadToolBar>
