Below is a shortened (some columns/styling removed) Grid I am workingon, I am trying to have an external source set IsReadOnly on the Parent and hierarchical grid.

The binding sets "cueSheetGrid" to IsReadOnly (InEditMode is a propery from DataContext) but the child grid (EventView) remains editable, I have not found a way to bind the child to the parent grid and the ItemSource is different for the two grids.

Any ideas?

<tGrid:RadGridView

IsReadOnly="{Binding InEditMode}"

x:Name="cueSheetGrid"

HorizontalAlignment="Stretch"

RowDetailsVisibilityMode="Collapsed"

AlternationCount="0"

RowIndicatorVisibility="Collapsed"

DragElementAction="None"

AreRowDetailsFrozen="False"

CanUserFreezeColumns="True" >

<tGrid:RadGridView.ChildTableDefinitions>

<tGrid:GridViewTableDefinition>

<tGrid:GridViewTableDefinition.Relation>

<tData:PropertyRelation

ParentPropertyName="CueEvents"/>

</tGrid:GridViewTableDefinition.Relation>

</tGrid:GridViewTableDefinition>

</tGrid:RadGridView.ChildTableDefinitions>

<tGrid:RadGridView.Columns>

<tGrid:GridViewDataColumn

DataMemberBinding="{Binding CueNum}"

Header="Cue Number "/>

<tGrid:GridViewDataColumn

DataMemberBinding="{Binding Label}"

Header="Label "/>

</tGrid:RadGridView.Columns>

<tGrid:RadGridView.HierarchyChildTemplate>

<DataTemplate>

<tGrid:RadGridView

x:Name="EventView"

ItemsSource="{Binding CueEvents}"

HeaderRowStyle="{DynamicResource MyHeaderRowStyle}"

Style="{DynamicResource GridStyleDefault}"

RowStyle="{DynamicResource EventRowStyle}"

AlternateRowStyle="{DynamicResource EventAltRowStyle}"

AlternationCount="2" >

<tGrid:RadGridView.Columns>

<tGrid:GridViewDataColumn

IsReadOnly="True"

DataMemberBinding="{Binding Machine.Name}"

Header="Machine "/>

<tGrid:GridViewDataColumn

DataMemberBinding="{Binding Position}"

Header="Position "/>

<tGrid:GridViewDataColumn

DataMemberBinding="{Binding Position}"

Header="Position "/>

</tGrid:RadGridView.Columns>

</tGrid:RadGridView>

</DataTemplate>

</tGrid:RadGridView.HierarchyChildTemplate>

</tGrid:RadGridView>

problem, RadWindow does not show in XBAP

hi!

I have a XBAP project for web, and I have a Page that shows a telerik components. I have a RadWindow as a usercontrol in this way:

My problem is when I try to show this window in my main program by clicking a button, code is like this:

frmDialogoEntradaDatos frmDialogo = new frmDialogoEntradaDatos();

frmDialogo.Mensaje = resxUsuarios.titSolicitudPassword;

frmDialogo.TipoDialogo = frmDialogoEntradaDatos.Tipo.TEXTO_PASSWORD;

frmDialogo.OnClose += new CloseEventHandler(EstablecerContraseña);

frmDialogo.Show();

frmDialogo is never shown, not even using ShowDialog(). I try to test original RadWindow instance like this:

RadWindow frmDialogo = new RadWindow();

frmDialogo.Width = 300;

frmDialogo.Height = 180;

frmDialogo.ShowDialog();

but nothing happen, but when using RadWindow.Alert(new DialogParameters() ... ); Works fine!

Thanks for your help

Refresh problem when changing grouped column value

I have a GridView that is grouped on a column named Status (which in this case is a GridViewComboBoxColumn even though I've seen the same behavior for GridViewCheckBoxColumn). When I change value of the Status and press Enter, the record is correctly moved to its new group, BUT the original group still holds a "ghost" record that cannot be modified. The only way to get rid of that record is to refresh the view manually by sorting or grouping.

Why does this happen? Must I refresh the view programmatically to avoid it?

Using IPagedCollectionView

I have an implementation of IPagedCollectionView that I'm using for custom paging of SQL data. Things seem to be working almost perfectly, but I have one issue that I need help with.

When I change pages in the RadDataPager my IPagedCollectionView is called appropriately, MoveToNextPage() is called. My code responds by retrieving the next page of data and changing the current page index value. The problem is that the RadGridView does not update its display with the result being that the new page of data is not displayed in the control. In debugging this I can see that the control is not calling GetEnumerator() after the page change. My suspicion is that the grid control is assuming that the enumerator will not change, just the contents of the collection will change. In my case I am changing the collection on each page change an expecting the grid control to perform a new enumeration by first calling GetEnumerator().

Comments?

*** Actually, changing the code to use the same collection for the enumeration does not improve things. Another data point is that the data pager does not update its display to indicate that a page change has happened. The data pager control always says that it is on page #1.

Keyboard Support

Which key presses are passed through to the KeyDown event? It seems that keys like page up/down are not passed through, just alpha keys, numbers, etc.

I need to get the other keys such as page up/down, arrow keys, etc. so that I can implement keyboard support for paging.

Thanks.

HierarchicalDataTemplate - Unlimited

public class Node

{

public Node(string myText)

{

this.Text = myText;

this.Nodes = new ObservableCollection<Node>();

}

public string Text { get; set; }

public ObservableCollection<Node> Nodes { get; private set; }

}

ObservableCollection<Node> nodes = new ObservableCollection<Node>();

nodes.Add(new Node("Company"));

nodes[0].Nodes.Add(new Node("Department"));

nodes[0].Nodes[0].Nodes.Add(new Node("here are you"));

radTreeView1.ItemsSource = nodes;

<Window.Resources>

<DataTemplate x:Key="itemTemplate">

<TextBlock x:Name="child" Text="{Binding Text}"/>

</DataTemplate>

<HierarchicalDataTemplate x:Key="masterTemplate" ItemsSource="{Binding Nodes}" ItemTemplate="{StaticResource itemTemplate}">

<telerik:RadTreeViewItem Header="{Binding Text}"/>

</HierarchicalDataTemplate>

</Window.Resources>

<Grid>

<telerik:RadTreeView Name="radTreeView1" ItemTemplate="{StaticResource masterTemplate}"/>

</Grid>

Why "here are you" is not displayed? This is the idea of HierarchicalDataTemplate or not?

Kind regards,

Marinko

How to set column's type

Hello,

I just started using Telerik's controls. After I set a DataTable as the source for the GridView, how do I tell it (in code) that, for instance, the column "image" is of type "GridViewImageColumn" and not string.

Thank you
