Deleting a column by drag-and-dropping

Can I override a column's behavior so that drag-and-dropping will allow not only to sort but to delete (or generate an event with delete request) them as well?

Customizing TreeListView using our own theme

Hi there,

I follow this example to customize Rad component using custom theme (Telerik support also gave me the sample code)
http://www.telerik.com/help/wpf/common-styling-apperance-themes-custom-theme-project-telerik-approach.html

However, when I tried to do the same thing with TreeListView, the TreeListView formatting is not what I expected.
I included these xaml file from InstallationRootPath\Telerik\RadControls for WPF Q3 2010\Themes\Windows7\Themes\Windows7

RadTreeListView.xaml
TreeListViewRow.xaml

And modify Telerik.Windows.Control.xaml into this:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<ResourceDictionary.MergedDictionaries>

<ResourceDictionary Source="/MyTheme;component/Themes/Slider.xaml" />

<ResourceDictionary Source="/MyTheme;component/Themes/RadTreeListView.xaml" />

<ResourceDictionary Source="/MyTheme;component/Themes/TreeListViewRow.xaml" />

</ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

But, the resulting RadTreeListView is not as I expect. Do I miss some steps to configure RadTreeListView?
Here is the link to sample code given by Telerik support from another thread.

Regards,

Arinto

Drag and Drop with windows explorer

Hi,

I know the windows explorer is not part of the WPF app. However, I need to create a WPF app that can actually drag the file from the windows explorer and drop it to a textbox control. As a result, the full path of the file appears on the textbox control. Does anyone know how to do this? do I need to create a wpf window to make a windows explorer so that I can have a full control over the drag and drop?

thanks

Selecting Linq to SQL parent using combo

Dear Telerik forum :)

I have a parent-child relation between two business objects (defined in Linq to SQL):
- Parent: TransactionAccount
- Child: Transaction

I want to show all transactions in a grid. Each transaction shall have a combobox displaying all available transactions. I also want to use the built in grouping and sorting functionality. After a bit of struggling with different options I came up with the following solution.

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding TransactionAccount.Name, Mode=OneWay}" Header="AccountName">

<telerik:GridViewDataColumn.CellEditTemplate>

<DataTemplate>

<ComboBox

DataContext="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=telerik:RadGridView}, Path=DataContext}"

DisplayMemberPath="Name"

IsEditable="False"

IsReadOnly="True"

ItemsSource="{Binding TransactionAccounts}"

SelectedItem="{Binding CurrentTransaction.TransactionAccount, Mode=TwoWay}" />

</DataTemplate>

</telerik:GridViewDataColumn.CellEditTemplate>

<telerik:GridViewDataColumn.AggregateFunctions>

<Data:CountFunction Caption="Count: " />

</telerik:GridViewDataColumn.AggregateFunctions>

</telerik:GridViewDataColumn>

This seems to work fine but in some particular cases (that I just cannot put my finger on) the parent Name is changed. So if I have two accounts Account1 and Account2, suddenly both have the same name.

ISSUE 1: So my question is: is this really the right approach? If so why does the binding update a property on my BO? I have tried every possible way to prevent that (IsEditable, IsReadOnly etc).

ISSUE 2: Another issue is that when I have the combo open on the last row and press Enter the focus goes "somewhere else" and the only way to resume navigation with the keyboard is to click on the application.

Thanks for any input!
