Values of X Axis

Hi,
I have create a RadChart based on a datatable that has 2 columns "XValue" and "YValue".

Dim

seriesMapping2 As New SeriesMapping

seriesMapping2.SeriesDefinition =

New BarSeriesDefinition

Dim itemMapping2 As New ItemMapping

itemMapping2.DataPointMember = DataPointMember.YValue

itemMapping2.FieldName =

"YValue"

seriesMapping2.ItemMappings.Add(itemMapping2)

RadChart1.SeriesMappings.Add(seriesMapping2)

When i execute the chart, the X axis labels values are 1,2,3, .... and i would like to put here the values of "XValue" column on my datatable. How can i do it?

Also, If I try to put string values to "YValue" column in mi datatable, the chart fails, that is, only numeric values can be put as source of a serie?.

Thanks a lot.

DatePicker Styling - Exception with Expression Blend

I would like to style and edit the control template of the RadDatePicker inside Expression Blend.

When I add a copy of either the control template or the style of it, i get the following exception (german error message):

"

An Exception was thrown.

StackTrace: Empty

Inner Exception: Der öffentliche Typ mit dem Namen "RadDatePicker" kann von dem Typverweis nicht gefunden werden

XamlParseException: Der öffentliche Typ mit dem Namen "RadDatePicker kann von dem Typverweis nicht gefunden werden

Translation of the message: "The public type with the name "RadDatePicker" can't be found by the reference type"

When I open the project with Visual studio, the exception does not occur.

Thanks in advance for helping.

GridView Filtering and Grouping issue

Hi,

Please bear with me as I am a newbie to WPF and we are evaluating RadGridView as part of a new development project. I have a issue with filtering and grouping on columns.

I have another Grid with Contact information with and a related table that stores other contact information, such as address details. If I have the Grid bound to a datarecord type of Contact and want to have related columns such as Address.Line1, Address.Line2 displayed on the parent GridRow. What is the best way to acheive this? I can get the information display but my issue is that I can not use the Filter or Groups on the Address columns. I have attached some simple code behind that I am using, Name works as expected, however Address.Line1 displays data but can not use filtering or the grouping functionality

    
            private void SetupGridView()  
        
            {  
        
                myGridView.Columns.Add(new GridViewDataColumn()   
        
                {  
        
                    HeaderText = "Name",  
        
                    UniqueName = "Name",  
        
                    DataMemberBinding = new Binding("Name")   
        
                });  
        
                myGridView.Columns.Add(new GridViewDataColumn()  
        
                {  
        
                    HeaderText = "Address Line 1",  
        
                    UniqueName = "Address.Line1",  
        
                    DataMemberBinding = new Binding("Address.Line1"),  
        
                    IsFilterable = true 
        
                });  
        
            }

Any help is greatly appreciated.

Drop after/before problem

Hi,

I am trying to prevent dropping of items on level other than their own , i.e., items on a specific level cannot be moved to level above or below). For this, I am working with PreviewDragEnded and if the item is not being dropped to the same level, i prevent it by setting e.Handled to true. It works fine when DropPosition is DropPosition.Inside. However, when the DropPosition is After or Before, the TargetDropItem is null ,for some reason, and I cannot check the level to which the item is dropped. The TargetDropItem gets a value on DragEnded event but it's already too late. Is there a way to do it?
Thank you,
Tal

Data Context

Hi. I would like to know if there is a way I can disable the DataContext property of a TreeViewItem so it will not fire for changes. I am not using DataBinding and I would like to use that DataContext just for keeping the object I am displaying to the user. Or maybe there is another way I can keep an object in the treeViewItem. Thanks
