Locating source for WPFSimulatedDragDropProvider.cs

Hi all,
I get this really nice error message "Locating source for 'c:\Builds\WPF_Scrum\Release_WPF\Sources\Development\Core\Controls\DragDrop\DragProviders\WPFSimulatedDragDropProvider.cs'"
in my test project for WPF and OpenAccess, when I drag a column header to the "Drag a column header and drop it here to group by that column" but only if the column I drag doesn't contain string data.
I'm using VS2010 and Telerik 2011 Q1 controls, columns in the RadGridview are autogenerated.

Any thoughts ?

Yours
Bjössi

[Solved] How can I bind the visibility property of a data series through code?

Hi,

The SimpleFiltering example binds the visibility of a data series to a view model via XAML, eg.:

<telerik:DataSeries

LegendLabel="EU-27">

<telerik:DataSeries.Definition>

<telerik:LineSeriesDefinition

ItemLabelFormat="0.#"

Visibility="{Binding Source={StaticResource ViewModel}, Path=SeriesEU27Visibility}" />

</telerik:DataSeries.Definition>

How can I achieve the same functionality via code (I'm coding in Visual Basic)? I'm buidling my data series dynamically through code, however I haven't able to figure out how to bind the visibility property via code.

Kind regards,
Dave.

Blend 4 & Telerik Control Styles

Dear Telerik,

I have been tasked with styling your RadExpander control using Blend 4 however when locating the Object > Edit Style... menu option in Blend I am faced with only the "Create Empty..." option, the expected "Edit A Copy" option is disabled.

Could this be something to do with referenced libraries? I used the "Convert to Telerik Project" option in Visual Studio to add all of the correct references so would expect them to be available.

Do you know of anything I could try in order to get this working?

Many Thanks

Ben

[Solved] access DataColumn's bound DataMember value within CellTemplate/CellStyle

Hi,

I have a business object which contains a fixed size collection of pattern values which I need to display within a single gridviewrow.
So the gridviewcolumn definition in xaml looks like:

<rad:GridViewDataColumn DataMemberBinding="{Binding Path=DigitPatterns[0], Mode=OneWay}" />
<rad:GridViewDataColumn DataMemberBinding="{Binding Path=DigitPatterns[1], Mode=OneWay}" />
<rad:GridViewDataColumn DataMemberBinding="{Binding Path=DigitPatterns[2], Mode=OneWay}" />

So far everything works perfectly.
The problem is that I need to specify a custom cell style which depends on a single pattern and not the whole business object.
But DataContext within a cell style or template always refers to the business object, so I'm not able to access the bound pattern anymore.

Is there any way to access the value of the DataMemberBinding from within a cell style or template ?

Thanks in advance

[Solved] Setting axis label block width

Is it possible to set the width of the y axis label block in code (C#)? I have 4 charts stacked and I want all of the x values to line up, but the labels on the y axis are different, so the plot areas of the charts are different sizes.

THanks,

RadComboBox adds extra blank item to dropdown

Hi, I have a slight problem with RadComboBox. I have 20 objects in a typed List that are bound to a combobox instance. The combobox has a DataTemplate attached to it, which displays two string properties from each object in a stack panel in each dropdown item. Unfortunately, the combobox dropdown contains 21 objects when it's opened: the 20 objects, as expected, but also one more completely blank item at the bottom. It can't be selected, and try as I might, I can't get this to stop appearing when the combobox's ItemTemplate is set to my DataTemplate. Oddly, it doesn't appear when ItemTemplate is not specified.

The nearest thing I could find which seemed related to this problem was this post from the middle of last year, the only difference being that the blank item at the bottom doesn't disappear when the combobox is reopened.

http://www.telerik.com/community/forums/aspnet-ajax/combobox/blank-item-shows-up-on-first-drop-down.aspx

Any help on this issue would be much appreciated.
