Is there a straightforward way of hiding the caption of an aggregate function in the footer while showing it in the group header? I'm looking into the footer template now to see how its put together, but was wondering if I'm missing a simple trick...

Thanks!

I have an editable data bound combobox. I need to know when the user is making a selection or editing.  On the selection changed event I use the prescribed method to capture the selected item "RadComboBoxItem selectedItem = chemical.SelectedValue as RadComboBoxItem;" . However selectedItem is always null even when chemical.SelectedValue is not. I have verified this using a line break in the code. What gives?

Hi!

I've a to display a list of  "households", I'm using a telerik component, the "RadGridView".

This is working, I've set the "Datacontext" on a parent element. I've no problem with that

<telerik:RadGridView Name="uxGridViewList" AutoGenerateColumns="False" ItemsSource="{Binding HouseHolds}" IsSynchronizedWithCurrentItem="True" >

    <telerik:RadGridView.Columns>

        <telerik:GridViewDataColumn Header="First Name" DataMemberBinding="{Binding FirstName}"/>

        <telerik:GridViewDataColumn Header="Last Name" DataMemberBinding="{Binding LastName}" />

        <telerik:GridViewDataColumn Header="City" DataMemberBinding="{Binding City}" />

        <telerik:GridViewDataColumn Header="Phone" DataMemberBinding="{Binding Phone1}"/>

    </telerik:RadGridView.Columns>

</telerik:RadGridView>

Now, I'm trying to get get information in some textbox changing to have the current selectedrow.

Changes will be made in two ways, so I've made some tries, but the textbox is still empty.

First try:

<TextBox Name="uxTextFirstName" Text="{Binding FirstName}" DataContext="{Binding ElementName=uxGridViewList, Path=CurrentItem, Mode=TwoWay}" />

Second try

<TextBox Name="uxTextFirstName" Text="{Binding ElementName=uxGridViewList, Path=SelectedItem.Firstname, Mode=TwoWay}"/>

What should I do more?

I tried to do in my code behind to check if I was having data in the correct format.
uxTextFirstName.Text = ((HouseHold)uxGridViewList.SelectedItem).FirstName;
It display correct informations, but don't change when I change lines and I really have to do this in the Xaml code, not in code behind.

EDIT: I just saw I got an error in the "Output":

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=uxGridViewList'. BindingExpression:Path=SelectedItem.Firstname; DataItem=null; target element is 'TextBox' (Name='uxTextFirstName'); target property is 'Text' (type 'String')

But I still don't understand what is wrong :(

Hello,
I'm sorry, but is it posible to make the HeaderRow always visible? We have hierarchical gridview with a lot of rows, so we need to scroll each child grid and not the whole grid, cause we don't want to loose  column headers from sight.
In general we need each child grid and parent grid have their own scrollbar.
Your article Visual Structure says: "Scroll bars - RadGridView will automatically show and hide scrollbars when needed. Choose between two types of scrolling: Real time and Deferred. Every hierarchical level has its own scrollbars. "
