If collection changes will error be thrown?

Hi there,

Just a quick question regarding the PersistenceFramework. I haven't used the feature yet but I have a scenario and I would like to know how the Framework will react to it.

Suppose I have TreeView filled dynamically from a database with various nodes and child nodes, say for example categories with sub products. If I save the properties of the treeview as is, and then later reload the treeview but its nodes have changed / been updated with newer products etc, will the persistence framework throw an error when reloaded with older persistence settings?

Thanks for your time and I hope I've explained myself adequately.

Layout of childrens

The task is to change the layout of elements in the component (like iGoogle dashboard).
To do that, you need to override the TileViewPanel methods.
The field of that type is not available in the TileView instance, but can be found in the visual tree.

Is there and option of substituting the TileViewPanel instance in the TileView visual tree for a custom class:

class MyTileViewPanel: TileViewPanel
{
// my methods
}

Metro Theme has problems

There is no indication of mouse over on selected items; note the Backstage Tab, selected Backstage Items and selected gallery items. (I'm not sure if that is a "feature" of the theme or not).
The QAT displays below the Ribbon in the same MetroColors.PaletteInstance.BasicColor that is used for mouse over, negating the mouse over visual queue.

Are there Metro Theme guidelines available, and if so where can they be found?

Thanks,
Steve

Drag and Drop between RadGridViews... again

After wrestling with this for a while and doing lots of research I have not been able to find a definitive answer. I can find a myriad of examples about drag and drop between other controls and the RadGridView but little to no examples about dragging from or between these types of controls. Searching back it seems that this is a hot topic for the past two years with solutions that temporarily worked or didn't at all. I'd like to say that I've tried harder for a solution but simply don't know how at this point. I've usually had wonderful success with the RadDragAndDropManager and all has been simple and easy except in this case. I just want to be able to drag a row from one RadGridView to another using the standard RadDragAndDropManager methods.

My main issue at this point is that I can't get a row to drag at all. I've tried applying a style to my GridView's RowStyle and to my column's CellStyle that sets the telerik:RadDragAndDropManager.AllowDrag to true but nothing happens. Strangely enough if I set telerik:DragDropManager.AllowDrag equal to true I get some dragging ability but it always says I have an invalid drop target by showing the crossed out circle curser.

Below is a simple application that I think should work but doesn't. I haven't bothered to set the drop properties yet. Please give me some pointers or an example that I can study to know what to do on this that is relevant to .NET 4.0 and recent releases. I am currently using the latest internal build as of 9/12/2011.

Thanks,
Adam

RadComboBox Text Property Binding MVVM

Hi,

I am having a hard time figuring out how to make the Text property of the RadComboBox bind to a string property in my View Model. I have a combo box that is Editable so that user can search for anything that starts with the values typed on the text box. I want to get that value in the view model, use it as part of a LINQ query (sarts with), and fill a collection source to display on a view.

The problem:
------------------
The string property on my view model "SearchText" is returning null (never gets the value entered by user). Sample code is below:

private List<SupplierMaster> foundSuppliers;

public List<SupplierMaster> FoundSuppliers

{

get { return foundSuppliers; }

set { if (foundSuppliers == value) return; foundSuppliers = value; OnPropertyChanged("FoundSuppliers"); }

}

private string searchText;

public string SearchText

{

get { return searchText; }

set { if (searchText == value) return; searchText = value; OnPropertyChanged("SearchText"); }

}

private void Search()

{

FoundSuppliers = (from sm in SupplierMaster where sm.SupplierName.ToUpperInvariant().StartsWith(SearchText.ToUpperInvariant()) select sm).ToList();    //Here the SearchText property is always null **ISSUE**

FoundSuppliers = FoundSuppliers.OrderBy(n => n.SupplierName).ToList(); }

}

XAML:

<telerik:RadComboBox Height="23" Name="txtSearchBox" TabIndex="1" HorizontalAlignment="Left"

Width="246" IsEnabled="True" VerticalAlignment="Top" IsEditable="True" IsTextSearchEnabled="True"

IsTextSearchCaseSensitive="True" Text="{Binding SearchText}"

TextSearchMode="StartsWithCaseSensitive" Margin="0,3"

ItemsSource="{Binding SupplierMaster}"

DisplayMemberPath="SupplierName"

SelectedValuePath="SupplierName"

SelectedItem="{Binding SelectedSupplier}" EmptyText="Name starts with..."

>

<telerik:RadComboBox.ItemsPanel>

<ItemsPanelTemplate>

<VirtualizingStackPanel />

</ItemsPanelTemplate>

</telerik:RadComboBox.ItemsPanel>

</telerik:RadComboBox>

Please advice if this is possible or if I am missing something.

Thanks,

Gabe.

Heatmap that isn't a "Map" ?

Can any of the telerik controls make a true "heatmap" .. i.e. one that's based strictly on data and not laid over an actual geographical map.

Something like:

http://finviz.com/map.ashx?t=sec

In that case, the data set is something along the lines of:

Sector (Light Blue)
Sub-Sector (Yellow)
Symbol - label for each box
Market Cap - Size of each box
Today's return - Color of each box, scaled from -3 for red to +3 for green.

Syncfusion has this: http://www3.syncfusion.com/products/user-interface-edition/wpf/chart/heat-map

?
