FormView.HeaderTemplate Property

Note: This property is new in the .NET Framework version 2.0.

Gets or sets the user-defined content for the header row in a FormView control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

[TemplateContainerAttribute(typeof(FormView))] 
public virtual ITemplate HeaderTemplate { get; set; }
/** @property */
public ITemplate get_HeaderTemplate ()

/** @property */
public void set_HeaderTemplate (ITemplate value)

public function get HeaderTemplate () : ITemplate

public function set HeaderTemplate (value : ITemplate)

Property Value

A System.Web.UI.ITemplate that contains the custom content for the header row. The default value is a null reference (Nothing in Visual Basic), which indicates that this property is not set.

The header row is displayed at the top of the FormView control when the HeaderText or HeaderTemplate property is set. You can define your own custom user interface (UI) for the header row by using the HeaderTemplate property. To specify a custom template for the header row, first place <HeaderTemplate> tags between the opening and closing tags of the FormView control. You can then list the contents of the template between the opening and closing <HeaderTemplate> tags. To control the style of the header row, use the HeaderStyle property. Alternatively, you can simply display text in the header row by setting the HeaderText property instead of this property.

NoteNote

If both the HeaderText and HeaderTemplate properties are set, the HeaderTemplate property takes precedence.

The following example demonstrates how to use the HeaderTemplate property to define a custom template to render for the header row.


<%@ Page language="C#" %>

<script runat="server">

  void EmployeeFormView_ItemCreated(Object sender, EventArgs e)
  {

    // Use the HeaderRow property to retrieve the header row.
    FormViewRow header = EmployeeFormView.HeaderRow;

    // Retrieve the HeaderLabel Label control from the header row. 
    Label headerLabel = (Label)header.FindControl("HeaderLabel");

    if(headerLabel != null)
    {
      // Display the current page number.
      int currentPage = EmployeeFormView.PageIndex + 1;
      headerLabel.Text = "Page " + currentPage.ToString();
    }

  }
  
</script>
