How do I initialize the controls in an InsertItemTemplate?
- by Slauma
I have - for instance - an asp:FormView which supports Read, Insert, Update, Delete and is bound to a DataSource:
<asp:FormView ID="FormView1" runat="server"
DataSourceID="ObjectDataSource1" >
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("MyText") %>' />
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("MyText") %>' />
</EditItemTemplate>
<InsertItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("MyText") %>' />
</InsertItemTemplate>
</asp:FormView>
If I am in Read-Mode or Edit-Mode the control is initialized with the property MyText of the current object which is bound to the FormView.
But when I go to Insert-Mode I do not have a "current object" (FormView1.DataItem is indeed null) and the controls are empty.
If I want to have my TextBox control initialized with a specific value how can I do that? In which event can I hook in to set default values to the controls in the InsertItemTemplate?
Especially I have in mind using an ObjectDataSource. I was expecting that the InsertItemTemplate is initialized with a business object which underlies my ObjectDataSource and which is created by the ASP.NET framework simply by using its default constructor when the InsertItemTemplate gets activated. In the default constructor I would init the class members to the default values I'd like to have in my controls of the InsertItemTemplate. But unfortunately that's not the case: No "default" object is created and bound to the FormView. So it seems I have to initialize all controls separately or to create the default object manually and bind it to the InsertItemTemplate of the FormView. But how and where can I do that?
Thanks in advance!
