Why does the demo app(s) fail to compile? !

I have downloaded the trial version of RadControls for WPF (the latest presumably as of 2011/2/27) and it fails to compile, showing massive numbers of errors. Why?

What are these .exe files within the solution?

I'm finding errors such as "The command "Copy .." ended with code 1." and
"Metadata file ..ScheduleView.exe' could not be found."
'Telerik.Windows..Examples.ScheduleView.FirstLook.ConflictCheckingDragDropBehavior.ValidateDrag( ..: return type must be .. to match overriden member ..
etc.

Has this demo-app been checked? Or is there something simple and obvious that I neglected to do? Thus far nothing seems to work as prescribed.

I'm using Visual Studio 2010 Ultimate, under Win7 x64, with 12GB of RAM. I appreciate your time and advice,

How to skip one level in hierachy of the data bound to TreeView?

Hi,

I have an entity whose structure is like this:

List of Universities
-->List of Colleges:
-->List of Students:
-->List of Assignments

I have list of universities with me which I want to bind to the tree and my requirement is to skip the node -"Student" in the tree so that it appears like-

University
-->College
---->Assignment

Is it possible using DataTemplate/HierarchicalDataTemplate of treeview?

Enable/Disable control in NewRow template

How can I enable/disable controls that are placed inside of NewRow? I have sort of methods that return values indicating that some controls must be enabled/disabled. When I click add new row in my gridview new row template appears and what I am expecting is that some controls must be enabled/disabled depend on values returned by methods.

Is this possible?
regards

Will there be a solution to align GridView Summary Row with columns in next release?

Hi

I am working on a project which requires a WPF grid control with ability to align summary row aggregates with grid columns and support column resize and reordering. It looks like this feature is not available in Telerik WPF GridView (yet) but I am wondering if there will be a solution for this in your upcoming release? This will be a key feature that might lead my client to pick different control suite at together.

Thanks
Ron Farko

TileView Horizontal navigation?

May be a dumb question, but what template do we edit to get the TileView to have horizontal tiles rather than vertical?

All examples show tiles on the right (stacked vertically), we'd like to stack them horizontally on top.

We're interested in the RadFluidContentControl example (FirstLook), but any template I edit (for the RadTileView) in Blend, I don't seem to see how you guys are drawing out the Tiles?

See attachment for a crude example.

Thanks!

overriding the Filtering Control with a Style Manager

I'm currently trying to use the GridView control with the Expression Dark Skin. I'm styling the whole control using the style manager. This works completely fine, however I've had to override the the filtering control to set a default option using the same technique as detailed in this thread:

http://www.telerik.com/community/forums/wpf/gridview/hide-and-filtering-options.aspx

When I do this the style of the filter control reverts back to the default Office Black theme. I thought about trying to set the style from code behind when I'm overriding the filter control, but I've no idea where to begin to do this. I've attached the relevant code below. Does anyone have any idea what the solution would be?

public class CustomFilteringControl : Telerik.Windows.Controls.GridView.FilteringControl

{

public override void Prepare(GridViewBoundColumnBase column)

{

base.Prepare(column);

if (column.DataType == typeof(string)) // Set contains as default only for string data type of the gridview column

{

FilteringViewModel vm = this.DataContext as FilteringViewModel;

if (vm != null)

{

if (!vm.Filter1.IsActive)

{

vm.Filter1.Operator = FilterOperator.Contains;

}

if (!vm.Filter2.IsActive)

{

vm.Filter2.Operator = FilterOperator.Contains;

}

RadGridView row edit canceled - view not restored

Hello,

I have a RadGridView Control and I can't get it to restore a row after canceling an edit.

For example if I'm editing one cell, then editing another cell in the same row then press ESC twice

I expect both of the cells to return to their previous state because the data source, correctly, isn't changed, but only

the last edited cell is changing.

It does work well however on your sliverlight demos, for example here: http://demos.telerik.com/silverlight/#GridView/Commands

Thanks

Selecting all rows in a group

Hello,

I have a RadGridView bound to a CollectionViewSource. The items in the collection view are sorted by Group Name (e.g "Group 1", "Group 2", etc...).

What is the best way to select all the items (based on group) when a user selects a single row?

Thanks!

Cast TreeViewItem as Object

Hi - I have a functioning tree view that is displaying a folder structure based collections of products, folders, and files. When I navigate to the file item, I would like to be able to double click the file and so be able to access the file object that was created for that item. In my double click event however, I am unable to cast the tree view item as my file class: I receive the error "Object reference not set to an instance of an object." for the line that attempts to cast the item as the file. Is there an alternate way to get at my file object ?

private void radTreeView_DoubleClick(object sender, MouseButtonEventArgs e)

{

e.Handled = true;

RadTreeViewItem selectedItem = e.OriginalSource as RadTreeViewItem;

LogFile logfile = selectedItem.Item as LogFile;

if (logfile != null)

{

MessageBox.Show("selected is file ");

return;

}

return;

}
