Is this possible?
If not, will it be possible on first release?
Any suggestion or example on dynamic drill-down?

When I hit the Add button in the DataForm, all other buttons are disabled except the Save and Cancel.  At this point there are fields that are not valid (required for instance), but the user can still hit Save.  Validation kicks in, but I would prefer that the Save button would remain disabled until all fields are valid.

When the Edit button is hit, only the Edit button is disabled.  If the user edits the form, the record is now dirty, but the user is able to hit any of the other buttons (Add, Delete, or the Navigation buttons).  Now granted if you navigate to another record and then come back your changes are still there, but the Save and Cancel buttons are disabled until you hit edit again.  At this point Cancel does not remove any changes.  I am not using AutoCommit.

I would prefer that Edit would disable all the other commands, and Save would only become enabled when the user actually makes a change, and as with the Add button, Save would remain disabled until all fields are valid.

I assume you have valid reasons for the current implementation; however I would like to be able to override this behavior with the aboved described behavior.  Can you provide any guidance?

What I'd really like is to have control over the CanExecute method of the commands.  Is there any way to acheive this?

Thanks in advance,
Steve

Hi,

I just want to use Telerik's "RadWindow".

<Window x:Class="_3DGraph.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        Title="MainWindow" Height="600" Width="800">
    <Grid>
        <telerik:RadWindow x:Name="radWindow1" Width="300" Height="300"></telerik:RadWindow>
    </Grid>
</Window>

using Telerik.Windows.Controls;
using Telerik.Windows.Controls.Navigation;

When I just click any of three buttons(minimize, maximize, close), I got this error... (I'm sending a screenshot)
What may be the problem?

And to move any RadWindow, do I have to write any code or it perceives movement behaviours automatically?

Hello,

I styled the FilteringControl on a RadGrid to include a converter on the list of distinct values to filter by.

I am using this code in the converter,

            var filter = value as FilteringViewModel;
            if (filter != null)
            {
                foreach (DistinctValueViewModel distinctValue in filter.DistinctValues)
                {
                    
                }
                return filter.DistinctValues;
            }

            return null;

But when I put a breakpoint on the code it says that DistinctValues.Count = 0 and the loop will not trigger.

However, after the converter returns it's value, it shows the distinct values correctly.

I am wondering why I cannot access the distinct list inside the converter because I know it returns the right value.

Thank you,

Warning: wall of text to follow....

I've read through the performance section of the help for the RadGridView and see where it says not to add a RadGridView as a child to something like a StackPanel or anything else where the children could grow to infinity because it will turn virtualization off for the grid. It further states that you should only add the grid to a container with a limited number of children.

That's a fairly huge design restriction, in my opinion. For example, I want to place a grid within a dockable/pinnable/unpinnable pane and include a RadExpander above it to allow the user to modify some options for that grid. The only way I can see of successfully getting everything to size/resize appropriately when the expander is expanded/collasped is to place it in a StackPanel with the Grid. However, doing so kills the perfomance.

So, I've had to resort to placing the options for the grid and the grid itself within two separate tabs in a RadTabControl. This, to me, is simply going to be confusing and combuersome for most of my users as the user will only be able to see either the options for the grid or the grid itself, not both.

I can't even force the grid to use virtualization nor can I get it to load its data asynchronously using the DataLoadMode property.... As a result, I feel I am being forced into providing a poor UI design for my users because the RadGridView's performance seems to drop off exponentially with the number of rows...

I just can't fathom why it's not possible to specify HorizontalAlignment="Stretch" and VerticalAlignment="Stretch" to give you the same "bounds" for the grid you would have otherwise within a container control that allows only one child to preserve the virtualization capabilities. That, or why it's not possible to improve the performance of the non-virtualized grid so it doesn't "hang" an application with a few thousand or more rows....

I need to hide some adorners during the selection change animation on the RadCarousel (and unhide them after).

I tried intercepting the SelectionChanging and SelectionChanged events, and hiding the elements there, but they don't hide!

So I thought maybe the system won't update the UI while an animation is running...so I then tried creating a simple animation to hide the adorner (again on the above mentioned events).  Still the UI changes don't change until after the selection animation has completed.

Is there a way to get around this?

Many thanks!
Chris

Vertical scrolling is so slow with GridViewDataColumn.CellTemplate.
You should improve performance with GridViewDataColumn.CellTemplate.
(It's fine with DataMemberBinding :)

Hello,

Can you please attach/supply a simple example of a RadGrid having RadComboBox, RadButton on its cells/rows? Thanks!
I badly need it. Thank you!

HI, 

I have a simple RadGridView on which I want to change the color of the text in a specific row (= 3 cells). Unfortunately, this code doesn't work:


What is wrong?

Thanks in advance.

Hi,
I want to apply an effect to a  Richtextbox I've used in my form. But Don't know how.
Please put a sample XAML here.
Thanks.
