How to retrieve distinct value-converted or formatted column values

Greetings,

How does one fetch the distinct values in a RadGridDataColumn as formatted via the binding's IValueConverter or StringFormat? The rdGrid.GetDistinctValues(column, true, null) method returns the raw unformatted values.

Is there a clever or easy way to get the formatted values as displayed in the grid?

Thanks

I figured it out. Here's how it can be done:

var distinctValues = uxGrid.GetDistinctValues(column, true, null);
var clip = string.Empty;
int count = 0;
Func<object, object> formatter;
if (column.DataMemberBinding.Converter != null) {
    formatter = _ => column.DataMemberBinding.Converter.Convert(_, column.DataType, null, CultureInfo.CurrentUICulture);
} else if (!string.IsNullOrEmpty(column.DataMemberBinding.StringFormat)) {
    formatter = _ => string.Format(_.ToString(), column.DataFormatString);
} else {
    formatter = _ => _;
}
foreach (var value in distinctValues) {
    clip += formatter(value) + "\n";
    count++;
}
clip = clip.TrimEnd('\n');
Clipboard.SetText(clip);

How can I close popup when click a middle level menu item?

Hi, I am using RadMenu to create a three layer menu.
It is something like :    -TopMenu
                                        -SecondLevel1 -ThirdLevel
                                        -SecondLevel2

Now, If I click "ThirdLevel" or "SecondLevel2", the menu will be closed automatically. But If I click "SecondLevel1", nothing happens. I know it is the logic you made it. But I want to close the menu when clicking "SecondLevel1". If there any way to do it?

I have to scroll to activate cell style triggers

I have an implicit style:

<telerik:RadGridView.Resources>

<Style TargetType="{x:Type telerik:GridViewCell}">

<Setter Property="Foreground" Value="Red" />

<Style.Triggers>

<MultiDataTrigger>

<MultiDataTrigger.Conditions>

<Condition Binding="{Binding IsAllowedToEdit}" Value="True"/>

<Condition Binding="{Binding Path=Column.IsReadOnly, RelativeSource={RelativeSource Self}}" Value="False"/>

</MultiDataTrigger.Conditions>

<MultiDataTrigger.Setters>

<Setter Property="Background" Value="#DBFFEC"/>

</MultiDataTrigger.Setters>

</MultiDataTrigger>

</Style.Triggers>

</Style>

</telerik:RadGridView.Resources>

But i have to scroll up and down, and one after another each row cells turns green if it is supposed to.

How can i fix this?

ToString() DataMemberBinding

I'm considering moving to Telerik grids. One of the issues I've come up against is that it doesn't look like I can perform bindings which relate to the bound objects ToString() method.

With WPF Toolkit DataGrids I could have a binding on a list view which looked like:

Binding="{Binding}"

This would mean that the ToString() method on the relivant object in the bound collection would be called and displayed.

On Telerik controls if I perform a binding such as:

DataMemberBinding="{Binding}":

Then I do not see this behaviour. Is this feature missing from your controls or do I have to approach this in another way? This is something I would really like to be able to do as it allows me to display composite data in a single field.

Thanks

TreeListView.ExpandAllHierarchyItems() problem

I'd like to expand all TreeListView nodes when the data is loaded. I tried to use DataLoaded event for it but got a problem. After calling ExpandAllHierarchyItems() in DataLoaded event handler, this event fires again and app goes into infinite loop. How can I handle with it? Note: I need expanded tree after each data update, not only once.

TreeListView ComboBoxColumn updating

I have a TreeListView and simple data binding with PropertyChanged notification. Selecting a ComboBox value causes updating of node's child elements in the tree but sometimes cells don't get updated. PropertyChanged() invoked, actual value changed but no reaction from grid. New values appear only after scrolling or shrinking\expanding tree node. I suppose this strange behaviour is due to cells virtualization but don't know how to fix it.

Configuring Metro Theme

Congrats on the forward thinking with respect to the Metro theme.

The docs are a little behind the code (we all sympathise), so I was wondering how to set the Metro theme, and select the Colors used in the theme. Purple is a bit....purple. :)

Metro Theme - Change Ellipse Color

I just downloaded the new Q2 bits (demo is impressively clean - nicely done!) and realized you're now offering a busy indicator similar to the one in Windows Phone - something I've been looking for for awhile now. The only question I have is if there is a way to change the color of the ellipses used in the control? I was looking through the them (BusyIndicator_style.xaml) and I can see where the fill is set to AccentBrush but I wasn't sure if it was possible to override this with another color. Purple doesn't really match my app very well.

Thanks in advance!

Edit: One thing that is missing from the demo is a way to change the theme on all the controls. What happened to that choice? I like the Metro one, but I would like to see some of the others too - especially for the main progress bar.
