Hi,

I've got a simple RadGridView showing an ObservableCollection<> which is bound at run-time as the user can select which type to load. On the same grid I let my users dynamically create expression columns. All works fine and as expected excepting for the Export() function which doesn't seem to include any columns of type GridViewExpressionColumn.

This is how I create the columns at run-time:

And this is how I export the grid:
Please advise on how to solve this problem.

Thanks

Hi

I want to have a textbox property in the property grid that supports multiple lines. I have overridden the EditorTemplate as follows:


When I run the code the long text does not wrap as expected.

Hi,

I have a chart with multiple series on it, representing time (x) vs speed (y) The 1st is supposed to span the entire length of the 'shift' and be drawn at 100 (%). The other series (there maybe many) will have points in between the 1st series' start and end time. However, when I do the data binding I get some strange visual results. The time line goes from e.g. 15:00:00 to 15:09:00 to 15:00:01, 15:00:02, etc.
It looks like the chart does not take into account that it's actually the same timespan for both series. I can supply the sample application if required. Any help would be appreciated.

Thanks!

Hi there.
Just started evaluating the product but am unable to quickly figure out how to make a chart dockable.  Can someone direct me to the correct implementation please.

I'm a bit confused on what my options would be for accomplishing the following:



Basically, I need 2 piecharts with 1 legend, and the additional data fields associated with the legend items you see in the pic.  The 2 charts and legend must all have the same colors for the data/series items.

I've read previous posts about specifying colors for the chart legend and series mappings by creating palettes and doing codebehind to assign colors to both series items and legend items manually.  However, I'm not sure if either of these fit with what I'm tasked to do.
 I'm not sure if I can add additional data in the legend (i've seen that there is a legend controltemplate but not a datatemplate) via templating or adding a gridview control to it. If i can't inject additional data into the legend, is there a way i can bind to the pie item colors?

Any advice would be appreciated.  Thanks.

Hello,

I have another UriImageProvider question. I have a series of images that my user can select from (via a drop down). When they select the image they want, I need my RadMap's UriImageProvider to grab the currently selected image information and display the image. Preferably, I would use the Byte Array that I have in memory to build the image on the fly and pass it to the provider. Worse case, I can write it to disk but I would rather avoid this. I can't seem to see a way to do this with Uri="{Binding...}". Any examples out there on how to dynamically change the Uri of the UriImageProvider?


Cheers,

Good afternoon.

I have some XAML that worked fine with release 2011.1.502.35, but I want to upgrade to the latest version (2011.3.11.16.0).

Unfortunately, I have a number of GridViews with GridViewDataColumn fields bound to nullable DateTime fields like this -

 

  <telerik:RadGridView.Columns>

    <telerik:GridViewDataColumn DataMemberBinding="{Binding Precedence}" Header="Precedence" IsReadOnly="True" />

    <telerik:GridViewDataColumn DataMemberBinding="{Binding Description}" Header="Description" />

            <telerik:GridViewDataColumn DataMemberBinding="{Binding OffenceFromDate}" Header="From Date"/>

            <telerik:GridViewDataColumn DataMemberBinding="{Binding OffenceToDate}" Header="To Date"/>

            <telerik:GridViewComboBoxColumn ItemsSource="{Binding RelativeSource={RelativeSource AncestorType=Page}, Path=DataContext.Queues}"

                                    SelectedValueMemberPath="OID"

                                    DataMemberBinding="{Binding AllocationQueue}"

                                    DisplayMemberPath="Name"

                                    Header="Assign To Queue"

                                    IsComboBoxEditable="True" />

  </telerik:RadGridView.Columns>           

</telerik:RadGridView>

When I load up a grid containing a row that contains a null value in either OffenceFromDate or OffenceToDate, I'm now getting the following exception -

Telerik.Windows.Controls.GridView.GridViewDataControl.MeasureOverride(System.Windows.Size)

System.NullReferenceException occurred
  Message=Object reference not set to an instance of an object.
  Source=Telerik.Windows.Data
  StackTrace:

  InnerException:

Is there any way around this? As I mentioned earlier, the older release was fine with these records.

Thanks for your time.

When the ItemsSource (ObservableCollection) is empty (Count = 0) calling BeginInsert does cause the AddingNewDataItem event to fire.  This works fine when ItemsSource has at least 1 item.

Is there a way in XAML to bind a property of a filterdescriptor for when it's active or not.  I'd like to define a filterdescriptor in XAML and bind whether or not it's active (i.e. applied to the gridview) to a MVVM property.

Hi,

Using the GridView definition below I get a Index out of bounds exception. This was working in 2011 Q2 but when I upgraded to Q3 I get this when I launch the application.
Any help would be much appreciated.

Thank you,

Vlad
