[Solved] Default values for ComboBox and DateTime Columns

[gerard van der galien]

Dear Madam or Sir,

We have a comboboxcolumn like:

<grid:GridViewComboBoxColumn DisplayIndex="5" Header="Bij/Af" ItemsSource="{Binding Data, Source={StaticResource ddsRekeningmutatiesoort}}" DataMemberBinding="{Binding Rekeningmutatie_RemsID, Mode=TwoWay}" DisplayMemberPath="Omschrijving" SelectedValueMemberPath="RemsID" />

We want for every inserted row a default Rekeningmutatie_RemsID = 4 (Bij=3,Af=4). The comboBox should already be preselected (default value) set to 'Af'.
 
This cannot be done with [DefaultValue(4)] in the domainservice metadata.

Also [DefaultValue(typeof(DateTime),DateTime.Parse("1-1-2010"))] does not work for DateTime columns.

Any ideas?

Johan

Hello gerard van der galien,

For the time being we do not support the implementation of such attributes as DefaulValue. However, it is in our to-do list and we do have plans for introducing this feature in RadGridView. 
For the time being you may use either the PreparingCellForEdit or BeginningEdit events of the grid to set the desired initial values. Another possible approach may be to set the default value in the constructor of the class filling up the data of the grid.
