Binding converter in code behind

USAFHokie80

Hi... So I'm creating a column collection for a data grid in the code behind because I don't know the number of columns needed until run time. I need to bind the background color to a converter but i'm not sure how to do it. The background property is typed as a Brush, but of course the converter is a binding... so how do I get this working? In the code below, the "DataMemberBinding" works because that property is a binding type... So I just need to get the background working. Thanks, Sam.

Dim c = New Telerik.Windows.Controls.GridViewDataColumn With {.Header = sched.ShipName,
.IsReadOnly = True,
.IsFilterable = True,
.IsSortable = True,
.Background = New System.Windows.Data.Binding With {.Converter = New BackgroundColorConverter(),
.ConverterParameter = (s + 1).ToString},
.IsGroupable = False,
.ShowFieldFilters = True,
.ShowDistinctFilters = False,
.DataMemberBinding = New System.Windows.Data.Binding With {.Converter = New ColumnConverter(),
.ConverterParameter = (s + 1).ToString}
}
columnCollection.Add(c)

Try something like this:

Dim column As New GridViewDataColumn With
{
.Header = sched.ShipName,
.IsReadOnly = True,
.IsFilterable = True,
.IsSortable = True,
.IsGroupable = False,
.ShowFieldFilters = True,
.ShowDistinctFilters = False,
.DataMemberBinding = New Binding With
{
.Converter = New ColumnConverter(),
.ConverterParameter = (s + 1).ToString
}
}

Dim backgroundBinding As New Binding With
{
.Converter = New BackgroundColorConverter(),
.ConverterParameter = (s + 1).ToString},
}

column.SetBinding(GridViewDataColumn.BackgroundProperty, backgroundBinding)

Thanks for the reply. SetBinding doesn't exist on the GridViewDataColumn type though... I did figure it out, however:

Dim c = New Telerik.Windows.Controls.GridViewDataColumn With {.Header = sched.ShipName,
.IsReadOnly = True,
.IsFilterable = True,
.IsSortable = True,
.IsGroupable = False,
.ShowFieldFilters = True,
.ShowDistinctFilters = False,
.DataMemberBinding = New System.Windows.Data.Binding With {.Converter = New ColumnConverter(),
.ConverterParameter = (s + 1).ToString}
}
Dim backgroundBinding As New System.Windows.Data.Binding With {.Converter = New BackgroundColorConverter,
.ConverterParameter = (s + 1).ToString}

            backgroundBinding.Source = c
            System.Windows.Data.BindingOperations.SetBinding(c, Telerik.Windows.Controls.GridViewDataColumn.BackgroundProperty, backgroundBinding)

            columnCollection.Add(c)

The BindingOperations.SetBinding method is an extension method. If you import the System.Windows.Data namespace, you'll be able to call it as c.SetBinding(...).

Hi, You can use DataGrid_AutoGeneratedColumns() event and set the datagrid.ColumnHeaderStyle, can set background color ,fore-color etc,with help ColumnHeaderStyle Property. I hope that it is useful for you. Thanks Mohit Saxena
