[Solved] Chequed property of checkbox adding a new record

[Javier]

Hi, I'm starting with the RadGrid control ...

I have a grid with several columns of type GridTemplateColumn

In this column, when i try to add a new record inplace, it returns me an error saying "The conversion of type 'DBNull' to type 'Boolean' is not valid."

<Telerik: GridTemplateColumn DataField = "Active" HeaderText = "Active" SortExpression = "Active"  UniqueName = "Active">
                 <itemtemplate>
                     <asp: CheckBox Enabled = "false" ID = "CheckboxlblActivo" runat = "server" Checked ='<%# Bind ( "Active")%> '>
                     </ asp: CheckBox>
                 </ ItemTemplate>
                 <EditItemTemplate>
                     <asp: CheckBox ID = "CheckboxActivo" runat = "server" Checked ='<%# Bind ( "Active")%> '>
                     </ asp: CheckBox>
                     </ EditItemTemplate>
</ Telerik: GridTemplateColumn>

How can I check that Bind ( "Active") is not null?  i'm adding a new record

<EditItemTemplate>
  <asp: CheckBox ID = "CheckboxActivo" runat = "server" Checked ='<%# Bind ( "Activo")%> '>
  </ asp: CheckBox>
</ EditItemTemplate>

Many thanks, any help o directions are appreciated
