Hello,
I intend to display a duration per XCategory, so I bound the YValue DataPointMember to a TimeSpan. I got an exception then. If I do bind to double value, everything works fine.
What should I do here ? I want to have a good formating on the bar and y-axis here (e.g. 2 Minutes, 1 hour, or 00:11:00).
Thanking you in anticipation

Hello,
I'm using the Carousel-control and need to collapse items in depency of some conditions. So I've tried to bind the Visibility-property of the item to a property of the corresponding object/viewmodel:
<Style TargetType="telerik:CarouselItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="telerik:CarouselItem">
<Grid ToolTip="{Binding Name}" Visibility="{Binding Visibility}">
.......
The result is, that the item is hided but not collapsed, although I set the property to collapsed.
Is there a possibility to collapse items?
Thank you!

Hello
In a situation I set the IsSelected-Property of some RowItems to true. The property "IsSelected" of "GridViewRow" is bound to the grid over DataBinding.
Now I wanted to make sure, that when I select an item from code, which is not visible at this time, it is scrolled into view. So I connected the SelectionChanged-Event of the GridView. The Problem is, the SelectionChanged-Event is only executed, if the item that I'm selecting is already in view! If it's way at the end of the list, the Event is never triggered and so I don't see which item gets selected. As soon as I scroll down and the item jumps into view, the SelectionChanged-Event is triggered.
Any suggestions how I can accomplish this? Things are very losely coupled so I can't just tell the GridView to select the item, it has to operate as soon as one of it's Items has the "IsSelected" property set.
Thanks

Hi,
We are using Teleriks Grid as well as WPF Datagrid. I want both grids to have the same styling. We want to go with Teleriks Vista Style. Since the styles are embebbed for telerik, will you be able to provide the styles to me?
Thnx & Rgds

Hi.
I just upgraded my project with the lastest DLL's of Q1 2010 version.
I have a view with a RadGridView control displaying a custom object, with the custom columns defined.
The definition of the columns is something like this:

Any idea of what's happening?
Is version Q1 2010 not stable for this control?
Thanks in advance.

Hi,
How can i access InvalidBorder of the row in Q1 2010 release?
In older release i use to do
void DataGrid_RowLoaded(object sender, RowLoadedEventArgs e)
{
Rectangle rect = e.Row.ChildrenOfType<Rectangle>()
.Where(c => c.Name == "InvalidBorder")
.First() as Rectangle;
But in Q1 2010 release this statement gives exception
"Expression cannot contain lambda expressions"
exception message says "Sequence contains no elements"
thx

Hello, we want to provide forms, e.g., to administer master data for article (Windows Forms or better WPF).
The users should be able to arrange themselves the fields (text fields, combo, etc.) to form the surface adaptably. Do you have a proposal, how can one realise such a thing?

Hi,
I have UserControl with RadGridView. If start it from WPF application everything is OK, but if I start from VB6 then grouping in RadGridView doesn't work. In earlier versions was ok.
Is there currently a work around for this issue?
Thanks in advance,
Evald
