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.

PageSize based on height

I'd like to have the pagesize for the data pager be dependent on how many items can fit in the gridview without scrolling. I'm assuming I can write code to do this, but was wondering if there might be a better way.

Sorting a grid bound to a DataTable

Hi,

I have a DataTable with numeric data that is bound to a RadGridView. When I sort a column by clicking the grid's header it is sorted by that column which is correct. The problem is that the sort applied to the column is a string sort and I would like it to sort numerically. I looked in the grid documentation under Sorting to no avail. Could you please tell me how this is done?

Best Regards,
Jose

GridViewDataColumn bound to a non primitive type raises exceptions internally

Let DoubleValue be a non primitive type wrapping a double, with a TypeConverter attached that knows how to convert it from/to a Double, and suppose a GridViewDataColumn is bound via DataMemberBinding to a property of this type. Editing the value causes an InvalidCast exception, from String to DoubleValue, in GridViewDataControl.OnKeyDown. Although the exception is captured internally, it is still visible in the Output window of VS.

Going through a ValueConverter in the DataMemberBinding does not make a difference here: the same exceptions are still raised.

The internally raised exceptions are unpleasant and can cause problems with e.g. copy/paste, which I have noted in separate post.
