INFO: Performing Inline Data Binding with the ObjectList Control (309496)

SUMMARY

This article illustrates how to use an ObjectList control to perform data binding within a template. The code samples in this article demonstrate how to perform data binding in the ItemDetails, Item, and AlternatingItem templates.

When you use an ObjectList control and perform inline data binding within a template, you must cast container objects to perform data binding correctly. This casting is required because the Microsoft Mobile Internet Toolkit uses the TemplateContainer class, which generates a generic template object. Because the object is generic, you must cast the template to the appropriate type when you perform data binding.

Perform Data Binding in an ItemDetails Template

Visual Basic .NET Sample

<mobile:TextBox 
   id="TextBox1" 
   runat="server" 
   Text='<%# DataBinder.Eval(Ctype(Ctype(Container.NamingContainer ,ObjectList).Selection.DataItem,DataRowView),"fieldname")  %>'>
				

<mobile:TextBox 
   id="TextBox1" 
   runat="server" 
   Text='<%# Ctype(Ctype(Container.NamingContainer,ObjectList).Selection.DataItem, DataRowView).Row("fieldname")  %>'>
</mobile:TextBox>
				

Visual C# .NET Sample

<mobile:TextBox 
   id="TextBox1" 
   runat="server" 
   Text='<%# DataBinder.Eval(((ObjectList)(Container.NamingContainer)).
Selection.DataItem, "fieldname") %>'>
</mobile:TextBox>
				

<mobile:TextBox 
   id="TextBox1" 
   runat="server" 
   Text='<%# (((DataRowView)((ObjectList)(Container.NamingContainer)).
Selection.DataItem).Row["fieldname"]) %>'>
</mobile:TextBox>
				

Perform Data Binding in an Item or AlternatingItem Template

Visual Basic .NET Sample

<mobile:TextBox 
   ID="TextBox1" 
   Runat="Server" 
   Text='<%# DataBinder.Eval(Ctype(Ctype(Container, ObjectListItem).DataItem, DataRowView), "fieldname") %>'>
</mobile:TextBox>
				

<mobile:TextBox 
   id="TextBox1" 
   runat="server" 
   Text='<%# Ctype(Container, ObjectListItem)("fieldname") %>'>
</mobile:TextBox>
				

Visual C# .NET Sample

<mobile:TextBox 
   id="TextBox1" 
   runat="server" 
   Text='<%# DataBinder.Eval(((ObjectListItem)Container).DataItem, "fieldname") %>'>
</mobile:TextBox>
				

<mobile:TextBox 
   id="TextBox1" 
   runat="server" 
   Text='<%# ((ObjectListItem)Container)["fieldname"] %>'>
</mobile:TextBox>
